In this article I’ve described:

How to develop simple Java service for the Android Devices; How to communicate with a service from the other processes and a remote PC; How to install and start the service remotely from the PC.
1. Java Service Development for the Android Devices

Services are long running background processes provided by Android. They could be used for background tasks execution. Tasks can be different: background calculations, backup procedures, internet communications, etc. Services can be started on the system requests and they can communicate with other processes using the Android IPC channels technology. The Android system can control the service lifecycle depending on the client requests, memory and CPU usage. Note that the service has lower priority than any process which is visible for the user.

Let’s develop the simple example service. It will show scheduled and requested notifications to user. Service should be managed using the service request, communicated from the simple Android Activity and from the PC.

First we need to install and prepare environment:

Download and install latest Android SDK from the official web site (http://developer.android.com); Download and install Eclipse IDE (http://www.eclipse.org/downloads/); Also we’ll need to install Android Development Tools (ADT) plug-in for Eclipse.

After the environment is prepared we can create Eclipse Android project. It will include sources, resources, generated files and the Android manifest.

1.1 Service class development

First of all we need to implement service class. It should be inherited from the android.app.Service (http://developer.android.com/reference/android/app/Service.html) base class. Each service class must have the corresponding declaration in its package’s manifest. Manifest declaration will be described later. Services, like the other application objects, run in the main thread of their hosting process. If you need to do some intensive work, you should do it in another thread.

In the service class we should implement abstract method onBind. Also we override some other methods:

onCreate(). It is called by the system when the service is created at the first time. Usually this method is used to initialize service resources. In our case the binder, task and timer objects are created. Also notification is send to the user and to the system log: public void onCreate() { super.onCreate(); Log.d(LOG_TAG, “Creating service”); showNotification(“Creating NotifyService”); binder = new NotifyServiceBinder(handler, notificator); task = new NotifyTask(handler, notificator); timer = new Timer(); }
onStart(Intent intent, int startId). It is called by the system every time a client explicitly starts the service by calling startService(Intent), providing the arguments it requires and the unique integer token representing the start request. We can launch background threads, schedule tasks and perform other startup operations. public void onStart(Intent intent, int startId) { super.onStart(intent, startId); Log.d(LOG_TAG, “Starting service”); showNotification(“Starting NotifyService”); timer.scheduleAtFixedRate(task, Calendar.getInstance().getTime(), 30000); }
onDestroy(). It is called by the system to notify a Service that it is no longer used and is being removed. Here we should perform all operations before service is stopped. In our case we will stop all scheduled timer tasks. public void onDestroy() { super.onDestroy(); Log.d(LOG_TAG, “Stopping service”); showNotification(“Stopping NotifyService”); timer.cancel(); }
onBind(Intent intent). It will return the communication channel to the service. IBinder is the special base interface for a remotable object, the core part of a lightweight remote procedure call mechanism. This mechanism is designed for the high performance of in-process and cross-process calls. This interface describes the abstract protocol for interacting with a remotable object. The IBinder implementation will be described below. public IBinder onBind(Intent intent) { Log.d(LOG_TAG, “Binding service”); return binder; }

To send system log output we can use static methods of the android.util.Log class (http://developer.android.com/reference/android/util/Log.html). To browse system logs on PC you can use ADB utility command: adb logcat.

The notification feature is implemented in our service as the special runnable object. It could be used from the other threads and processes. The service class has method showNotification, which can display message to user using the Toast.makeText call. The runnable object also uses it:

public class NotificationRunnable implements Runnable { private String message = null; public void run() { if (null != message) { showNotification(message); } } public void setMessage(String message) { this.message = message; } }

Code will be executed in the service thread. To execute runnable method we can use the special object android.os.Handler. There are two main uses for the Handler: to schedule messages and runnables to be executed as some point in the future; and to place an action to be performed on a different thread than your own. Each Handler instance is associated with a single thread and that thread’s message queue. To show notification we should set message and call post() method of the Handler’s object.

1.2 IPC Service

Each application runs in its own process. Sometimes you need to pass objects between processes and call some service methods. These operations can be performed using IPC. On the Android platform, one process can not normally access the memory of another process. So they have to decompose their objects into primitives that can be understood by the operating system , and “marshall” the object across that boundary for developer.

The AIDL IPC mechanism is used in Android devices. It is interface-based, similar to COM or Corba, but is lighter . It uses a proxy class to pass values between the client and the implementation.

AIDL (Android Interface Definition Language) is an IDL language used to generate code that enables two processes on an Android-powered device to communicate using IPC. If you have the code in one process (for example, in Activity) that needs to call methods of the object in another process (for example, Service), you can use AIDL to generate code to marshall the parameters.

Service interface example showed below supports only one sendNotification call:

interface INotifyService { void sendNotification(String message); }

The IBinder interface for a remotable object is used by clients to perform IPC. Client can communicate with the service by calling Context’s bindService(). The IBinder implementation could be retrieved from the onBind method. The INotifyService interface implementation is based on the android.os.Binder class (http://developer.android.com/reference/android/os/Binder.html):

public class NotifyServiceBinder extends Binder implements INotifyService { private Handler handler = null; private NotificationRunnable notificator = null; public NotifyServiceBinder(Handler handler, NotificationRunnable notificator) { this.handler = handler; this.notificator = notificator; } public void sendNotification(String message) { if (null != notificator) { notificator.setMessage(message); handler.post(notificator); } } public IBinder asBinder() { return this; } }

As it was described above, the notifications could be send using the Handler object’s post() method call. The NotificaionRunnable object is passed as the method’s parameter.

On the client side we can request IBinder object and work with it as with the INotifyService interface.  To connect to the service the android.content.ServiceConnection interface implementation can be used. Two methods should be defined: onServiceConnected, onServiceDisconnected:

ServiceConnection conn = null; … conn = new ServiceConnection() { public void onServiceConnected(ComponentName name, IBinder service) { Log.d(“NotifyTest”, “onServiceConnected”); INotifyService s = (INotifyService) service; try { s.sendNotification(“Hello”); } catch (RemoteException ex) { Log.d(“NotifyTest”, “Cannot send notification”, ex); } } public void onServiceDisconnected(ComponentName name) { } };

The bindService method can be called from the client Activity context to connect to the service:

Context.bindService(new Intent(this, NotifyService.class), conn, Context.BIND_AUTO_CREATE);

The unbindService method can be called from the client Activity context to disconnect from the service:

Context.unbindService(conn); 1.3 Remote service control

Broadcasts are the way applications and system components can communicate. Also we can use broadcasts to control service from the PC. The messages are sent as Intents, and the system handles dispatching them, including starting receivers.

Intents can be broadcasted to BroadcastReceivers, allowing messaging between applications. By registering a BroadcastReceiver in application’s AndroidManifest.xml (using tag) you can have your application’s receiver class started and called whenever someone sends you a broadcast. Activity Manager uses the IntentFilters, applications register to figure out which program should be used for a given broadcast.

Let’s develop the receiver that will start and stop notify service on request. The base class android.content.BroadcastReceiver should be used for these purposes (http://developer.android.com/reference/android/content/BroadcastReceiver.html):

public class ServiceBroadcastReceiver extends BroadcastReceiver { … private static String START_ACTION = “NotifyServiceStart”; private static String STOP_ACTION = “NotifyServiceStop”; … public void onReceive(Context context, Intent intent) { … String action = intent.getAction(); if (START_ACTION.equalsIgnoreCase(action)) { context.startService(new Intent(context, NotifyService.class)); } else if (STOP_ACTION.equalsIgnoreCase(action)) { context.stopService(new Intent(context, NotifyService.class)); } } }

To send broadcast from the client application we use the Context.sendBroadcast call. I will describe how to use receiver and send broadcasts from the PC in chapter 2.

1.4 Android Manifest

Every application must have an AndroidManifest.xml file in its root directory. The manifest contains essential information about the application to the Android system, the system must have this information before it can run any of the application’s code. The core components of an application (its activities, services, and broadcast receivers) are activated by intents. An intent is a bundle of information (an Intent object) describing a desired action — including the data to be acted upon, the category of component that should perform the action, and other pertinent instructions. Android locates an appropriate component to respond to the intent, starts the new instance of the component if one is needed, and passes it to the Intent object.

We should describe 2 components for our service:

NotifyService class is described in the tag. It will not start on intent. So the intent filtering is not needed. ServiceBroadcastReceived class is described in the tag. For the broadcast receiver the intent filter is used to select system events: … … 2. Java service remote installation and start 2.1 Service installation

Services like the other applications for the Android platform can be installed from the special package with the .apk extension. Android package contains all required binary files and the manifest.

Before installing the service from the PC we should enable the USB Debugging option in the device Settings-Applications-Development menu and then connect device to PC via the USB.

On the PC side we will use the ADB utility which is available in the Android SDK tools directory. The ADB utility supports several optional command-line arguments that provide powerful features, such as copying files to and from the device. The shell command-line argument lets you connect to the phone itself and issue rudimentary shell commands.

We will use several commands:

Remote shell command execution: adb shell File send operation: adb push Package installation operation: adb install .apk

I’ll describe the package installation process in details. It consists of several steps which are performed by the ADB utility install command:

First of all the .apk package file should be copied to the device. The ADB utility connects to the device and has limited “shell” user privileges. So almost all file system directories are write-protected for it. The /data/local/tmp directory is used as the temporary storage for package files. To copy package to the device use the command: adb push NotifyService.apk /data/local/tmp
Package installation. ADB utility uses special shell command to perform this operation. The “pm” (Package Manager?) utility is present on the Android devices. It supports several command line parameters which are described in the Appendix I. To install the package by yourself execute the remote shell command: adb shell pm install /data/local/tmp/NotifyService.apk
Cleanup. After the package is installed, ADB removes the temporary file stored in /data/local/tmp folder using the “rm” utility: adb shell rm /data/local/tmp/NotifyService.apk.
To uninstall package use the “pm” utility: adb shell pm uninstall 2.2 Remote service control

To be able to start and stop the NotifyService from the PC we can use the “am” (Activity Manager?) utility which is present on the Android device. The command line parameters are described in the Appendix II. The “am” utility can send system broadcast intents. Our service has the broadcast receiver which will be launched by the system request.

To start NotifyService we can execute remote shell command:

adb shell am broadcast –a NotifyServiceStart

To stop the NotifyService we can execute remote shell command:

adb shell am broadcast –a NotifyServiceStop

Note, that the NotifyServiceStart and NotifyServiceStop intents were described in the manifest file inside the … tag. Other requests will not start the receiver.

Appendix I. PM Usage (from Android console) pm [list|path|install|uninstall] pm list packages [-f] pm list permission-groups pm list permissions [-g] [-f] [-d] [-u] [GROUP] pm path PACKAGE pm install [-l] [-r] PATH pm uninstall [-k] PACKAGE The list packages command prints all packages. Use the -f option to see their associated file. The list permission-groups command prints all known permission groups. The list permissions command prints all known permissions, optionally only those in GROUP. Use the -g option to organize by group. Use the -f option to print all information. Use the -s option for a short summary. Use the -d option to only list dangerous permissions. Use the -u option to list only the permissions users will see. The path command prints the path to the .apk of a package. The install command installs a package to the system. Use the -l option to install the package with FORWARD_LOCK. Use the -r option to reinstall an exisiting app, keeping its data. The uninstall command removes a package from the system. Use the -k option to keep the data and cache directories around after the package removal. Appendix II. AM Usage (from Android console) am [start|broadcast|instrument] am start -D INTENT am broadcast INTENT am instrument [-r] [-e ] [-p ] [-w] INTENT is described with: [-a ] [-d ] [-t ] [-c ] …] [-e|--es ...] [--ez ...] [-e|--ei ...] [-n ] [-f ] [] Resources used:

Tips

What is Android?
Android is a mobile operating system initially developed by Android Inc., a firm purchased by Google in 2005. Android is an open source mobile phone platform based on the Linux operating system. As a flagship participant in the Open Handset Alliance (OHA), Android operating system can be installed by all the members from the Open Handset Alliance including Google, HTC, Dell, Intel, Motorola, Qualcomm, Texas Instruments, Samsung, LG, T-Mobile, Nvidia, and Wind River Systems and more.

Android phones
Android phones refer to phones that use Android as a mobile operating system including HTC, Samsung, Motorola, LG, Sony Ericsson, Acer Inc, Garmin, HKC, Dell, Huawei, Lenovo, Pantech and more. Usually, Android phones support H.263, H.264 (in 3GP or MP4 container), and MPEG-4 SP video format. If you want to play AVI, Xvid, DivX, MKV, WMV, RM, FLV, SWF, ASF, MPG, MOV, MPEG, MPG, HD, MTS, M2TS, TS in Android phone, you need to convert them to Android phone format like MP4, 3GP.

Why choose Android phone
Android phone includes various phone models, and different phone model has its specific features. But they also have common features which make Android phone more competitive.
Android phone can run multiple apps at the same time whether they are system apps or apps from the Android Marketplace. At this respect, Android phone is even more competitive than iPhone OS which does offer limited multitasking, but only allows native applications such as Mail, iPod and Phone to run in the background.

Managing Your Battery Life
A criticism that I hear often is that Android phones have very poor battery life. That was actually true with the earliest fashions, and it might still be true with the newer handsets. Fortunately, there are a variety of tools for managing your battery life that may assist you squeeze the most from your Android phone’s battery.

A few of the options of Android aren’t needed on a constant basis. These include Bluetooth, WiFi and GPS. These options can quickly drain the phone battery if they are working continuously. Fortunately, Android version 1.6 added some tools to make it simpler to modify this stuff off in an effort to increase battery life. There is a widget you can add to your phone’s desktop that lets you switch these options ON and OFF with a single touch. Many purposes have the flexibility to toggle these ON and OFF as properly so if an utility wants one in all these options, it can activate it.

Another frustrating side of managing your battery life on Android is that the default battery meter solely displays a coloration: inexperienced, yellow and red to point how much battery energy remains. This could make it more durable to gauge if an utility is draining your battery more quickly than normal. Battery Meter Lite is a free software that features a battery remaining notification. When this notification is enabled a battery icon with the percentage of battery remaining will seem in your notification area. This makes it a lot simpler to manage your battery life because you know precisely how much battery energy remains.

Managing Duties
Typically you need to know what duties are working and have an approach to cease a running task. This is very true when you have got an older Android telephone with a slow processor. System Panel Lite is a superb application for this. When you’ve got got ever used an Unix based mostly working system or Linux, System Panel Lite will remind you of the highest application. It gives an inventory of actively working processes and inactive however cached processes. It additionally offers you some helpful charts of the current CPU usage and reminiscence usage. Clicking on a working utility, you may see the individual application’s CPU and memory utilization and you have got the option of killing the process. By default, system processes are hidden from view but there is an possibility in settings to see the Android system processes as well.

Getting Extra from Messaging
Once I first acquired my Android cellphone, I hated the default messaging application. I shortly found Handcent SMS, a free utility that replaces the default messaging application. Handcent features a threaded interface to can assist you visually see the forwards and backwards dialog you are having through SMS. It additionally allows sending footage via MMS and saving MMS attachments. You presumably can set Handcent because the default messaging utility on Android. Handcent will even present notifications for brand new SMS messages. The notification might be personalized a bit, including what colour your cellphone LED should flash when you might have new messages. While you change to Handcent, you will have to enter the default messaging utility and switch off its notifications. Otherwise, you’re going to get two notifications each time you obtain a message.

Ditch Your iPod
Let’s face it – carrying a phone and a music player is a pain. Luckily, you can simply change your iPod along with your Android phone. The default music player that ships with Android is agreeably nothing to put in writing home about. The interface may be very simple and albeit, fairly boring. However, you may simply exchange it with the Cubed Media Participant from the Android market.

Cubed is a free media participant with a considerably unique consumer interface. Album paintings appears in a third-dimensional cube. By rotating the cube up or down, you presumably can flick thru your album paintings in a fashion similar to iPod’s cover flow. Rotating the dice to the left or proper lets you alphabetically flip by means of your collection. This will be a nice utility for turning your Android phone into a completely featured media player.

Android is an working system for smartphones, tablets, and internet books. But the precise meaning of the Android is a robot that’s developed to look and act like humans. Presently Android Operating system is essentially the most used cellular working system with over 33% of its share in the good cellphone market in 2010. These statistics explains us all the story of how vital function the Android phones are enjoying in human day-to-day life. With over 12 million lines code, android operating system is the integration of Java, XML, C, C++ languages. Being such an necessary and loopy product, Android’s have crossed the Symbian, Blackberry OS in 2010 statistics, because of this the concentration was now shifted to Android phone and tons of official as nicely as private developers had been deeply involved in creating the most effective Android apps for Android phone.

Android Software Development

Android is Google’s operating System derived from the Linux V2.6 Kernel. Android is a mobile phone operating system and gained utmost attention from the entire world due to the popularity of Google and for its quick encroachment into the Smartphone’s market. Earlier, Apple’s iOS is the only popular mobile operating system that is very much familiar with the world besides the less popular Nokia’s Symbian. Android’s entry has completely changed the mobile phones market and created ripples everywhere all over the world. Android gained significant level of success over the popular Apple’s iOS and giving it a great run to it too. Android already crossed many milestones in its tenure with various updated version operating systems. This Android operating system is a brain child of Open Handset Alliance, which is a group, led by none other than the popular Google. Google brand name also supported and helped a lot for its success and the current growth.

Many handset manufacturers also supported well this novice operating system when it was entered into the mobile phones arena. Now, Android’s success has created huge business in the form of Android Application Development and Android software development. Mobile phone market also witnessed huge improvement in their business through the kind of competition it developed with the popular Apple and its Smart phone iPhone. Smartphone market witnessed significant improvements and changes due to the Android entry. This is definitely a good sign and growth for many different frontiers in the world. Android development is currently taking place in huge volume all over the world due to the significant improvement Android based smart phones usage throughout the world. Android is definitely a greatest addition for the entire world in many ways.

Android is a complete open source stack that was created exclusively for smart phones and some other similar devices as tablets and others. This is a complete bundle of many dissimilar other open source projects. Here, Android has come up with a unique step as AOSP, which stands for Android Open source project. This AOSP is derived to enable expansion for Android and for its safety. Android based smart phones are currently having huge market all over the world and successfully overtaken the monopoly of the Apple’s iOS and its devices. Android application development is gaining great momentum due the huge volume smart phones that are running on this operating system and due its Open Source feature along with spontaneous nature. All these reasons are successfully gained lion share in the market for Android through its devices. Definitely, still Android got a long way to go keeping in mind the popularity of Apple and its iOS based devices’ popularity.

Android operating system uses programming language Java for its development needs. Android programmers India is popular with this application development. This kind of ability is created a huge space for India for the outsourcing android development successfully. Android developers are available in huge volume in India due to its compatibility with the programming language Java. Many international companies are sending all their development needs related to it successfully to India for this reason. This is a good sign for India in business point of view and to excel well in the mobile application development frontiers successfully. Android Software Development is no longer a toughest task as many seasoned programmers are already gained a greater foothold in it successfully. Many latest Android apps are significantly proving this aspect from the Google Market World. Android has been popular household name unlike earlier due to its lion share in the current smart phones’ market.

It is true that Android platform uses programming language Java for its development needs, but this operating system runs the standard Java byte code as a special virtual machine for all its development needs. This thing should be a great knowledge for all the Android developers before proceeding for the application development. Android successfully supports 3D graphics along with 2D through its OpenGL libraries. Also, it can support database storage in a SQLite database format too. Android apps developers should have a great knowledge about this aspect for their Android development. Most of the Android application development needs specifically governed through the operating system’s special features as the every latest version of Android comes up with many new additions and deletions in it. Android programmers should have a greater control over the each Android version to shape up the application well and compatible for all versions successfully.

Life cycle of the application is always dependent on its operating system due to various reasons. Here, Android is always special at this aspect and defines application life cycle for its activities through the operating system’s pre-defined methods. Many programmers find this ability as more encouraging as operating system always got a chance to destroy the application through stopping itself. Android is definitely a well designed operating system to meet every need of today successfully. Its open development platform is a greatest advantage for all Android programmers. Rich standardized applications are very much possible through this ability. Importantly, Android operating system offers application developers complete freedom to take advantage of the hardware of the device, which will result into effective application from the developers.

Currently, Android application development is a popular source of business for many Android developers India. Also, outsourcing Android application is quite rampant at this moment as there is huge volume of application development needs are prevailing all over the market due to the increased Android based Smartphone users all over the world. Android application developers in India are well qualified for these various tasks and there is a huge chance for the every application to reach the desired standards expectations successfully. Android is already earned a lion share in the market and still running successful over its contemporaries. Now, its only opponent Apple’s iOS is failing to gain upper hand over Android on some of the vital aspects such Voice over facility and some more. It is the perfect time for Android to grow further and excel well over its opponent through completely overshadowing its current monopoly.

What is Android?

Android is the world’s most popular mobile platform. Android is an operating system made by Google. It is an open source platform. Android brings in the power of Google in handheld devices and tablets. It has an amazingly fast browser. Android is developed by the Open handset Alliance led by Google.

The operating system used in Android is Linux.  Google has done further architectural changes in the Linux Kernel which are typically outside the Linux Kernel Development Cycle. The first commercially launched Android smartphone was on HTC Dream.

Features

All android handsets are adaptable to larger VGA, 2D graphics library, 3D graphics library based on OpenGL ES 2.0 specifications, and traditional smartphone layouts. The android provides connectivity through GSM/Edge, IDEN, CDMA, EV-DO, UMTS, Bluetooth,  Wi-Fi, LTE, NFC and WiMax.

Android phones are equipped with video cameras, touchscreens, GPS, accelerometers, magnetometers, dedicated gaming controls and accelerated 3D Graphics. Android phones also support multitouch.

It uses SQLite, a light weight relational database to store user’s data. Android has a fast speed web-browser based on open source WebKit layout engine. Android supports voice actions for calling, texting and navigation etc. from Android 2.2. It allows wireless tethering, enabling your phone to become a Wi-Fi hotspot.

Android supports SMS, MMS, threaded text messaging and cloud to device Messaging (C2DM). Options for multitasking are available in Android. For external storage, most android phones have a micro SD slot and can read micro SD cards formatted with FAT 32, Ext3fs or Ext4s file system. Screen capturing is also possible in Android by pressing the power buttons and volume down buttons simultaneously. All these features help hoards of developers in the development of high-end Android based games and android based applications.

Uses

Android enables its users to video chats with friends and family, find fancy restaurants. Android allows users to get directions while they are travelling with the help of GPS feature. It allows users to listen to online music and view video content.

Android has been designed primarily for smartphones and tablets. The open-source nature of android allows it to be used on laptops, netboooks, smartbooks, and eBook readers and has attracted an increase in android application development and android games development over the years. The android OS finds it use in car CD and DVD players, vehicle satnav systems, refrigerators, home automation systems among others.

Security and Privacy

The Android platform has been developing at an almost dizzying pace lately. The number of new releases in a short period of time has lead many to warn that fragmentation has become a serious danger to Android. Google’s Android team has responded saying that the Android fragmentation is a myth. Is fragmentation of Android a myth or is it something that should concern Android developers?

Fragmentation has affected Linux and other open source systems in the past. It occurs when a system has multiple versions with very different components. For example, Linux distributions have their own file system arrangements, different window managers and different packaging systems. This makes it difficult for application developers to create applications for Linux on the expectation that certain components will exist or be in the same location.

Causes of Fragmentation
Android has suffered from some of the classic causes of fragmentation. First, there are wide differences in the capabilities of the hardware devices on which Android runs. While in many systems, this could easily lead to severe fragmentation, Android has not been as affected by this. Android is, however, being very rapidly developed. Each new version of Android has added capabilities. Handsets on the market are running as many as five different versions of the Android operating system. This is where the greatest danger of fragmentation lies. Finally, different manufacturers have been dressing up Android with various add-ons and custom user interfaces. These variations in how Android looks and feels can also lead to fragmentation.

Google has responded to the many reports of Android fragmentation by calling it a “myth”. They have put in place some systems and a plan that should help address the issue of fragmentation. Google is so sure of these plans that they believe fragmentation does not exist.

Fragmentation Prevention
One approach that Google is taking to prevent fragmentation is slowing down the development of Android. The rapid development allowed Google to add new functionality to Android and reach a level of maturity that makes Android competitive with other smartphone platforms. Now that Android is fully featured, the development can slow back down.

Along with slowing down the development of Android, Google has developed a plan to make Android more modular. This will allow users of Android based systems to update individual components of the Android system even if their carrier has not moved to a newer version of Android. For example, if a new version of Gmail is released, users can decide to upgrade Gmail on their phones. This modularity is being applied to various systems including items like the keyboard.

Another approach that Google has taken to try and prevent fragmentation of Android is to adopt a series of standards that must be followed to gain access to the Android market. These standards define minimal functionality that a handset must have in order for the carrier to ship the Android market with the phone. By controlling the market, Google has ensured that these standards will be adhered to. These standards generally deal with hardware and include things like every Android handset must have a camera. By using these standards, Google can assure developers that certain functionality will always be available on an Android phone.

Intents are another type of standard that Google uses to avoid functionality. An intent is a type of interface that Android uses. For example, an application that sends email will use an intent to launch a an email composition window. By using intents, it is possible to replace the default email client with another application and still have the expected behavior from other applications that write email.

Custom User Interfaces
While these systems certainly seem to help reduce the risk of fragmentation, calling it a myth seems to be a bit bold on Google’s part. The biggest source of potential fragmentation seems to be custom user interfaces being applied to Android by various phone makers. It is not uncommon to see updates to applications in the Android market geared towards fixing a bug with a manufacturer’s custom UI. Of course, using anecdotal evidence from the Android market to determine if custom user interfaces are fragmenting Android is not a very solid approach. It seems reasonable, however, that heavy customization of how Android looks and feels will fragment the platform.

This threat goes beyond just creating problems for developers. End users will not be able to pick up any Android handset and expect it to work in the same way. Various custom Androids start to present a learning curve for the end users which may reduce the uptake of Android.

Google says that fragmentation of Android is a myth based on the systems that they have in place to combat fragmentation. However, it does appear from browsing the market that developers are struggling somewhat with supporting the various versions of Android, the different handsets and especially the many custom user interfaces. Is fragmentation really a myth? Post a comment with your thoughts, especially if you are developing for Android and have encountered compatibility issues with a custom user interface.
