Basics applications of Android: 

Basics applications of Android Android applications are composed of one or more application components (activities, services, content providers, and broadcast receivers ). Each component performs a different role in the overall application behavior, and each one can be activated individually (even by other applications)

Basics applications of Android: 

Basics applications of Android The manifest file must declare all components in the application and should also declare all application requirements, such as the minimum version of Android required and any hardware configurations required Non-code application resources (images, strings, layout files, etc.) should include alternatives for different device configurations (such as different strings for different languages)

Android Features: 

Android Features Application Framework that enables reuse and replacement of components. Optimized Graphics that is powered by customized 2D graphics library and 3D graphics based on the OpenGL ES 1.0 specification Provision of Bluetooth, EDGE, 3G and Wi-Fi . SQLite for structured data storage Open source Web Kit engine based integrated web browser .

Android Features: 

Android Features Camera, GPS, Compass, and Accelerometer (dependent on hardware support) GSM Telephony Dalvik virtual machine optimized for mobile devices. GSM Telephony Dalvik virtual machine optimized for mobile devices .

Android's Latest: 

Android's Latest Browser: It also supports popular web standards like CSS 3D, Animations . It also supports playback of HTML5 video content . Gallery: Now the gallery supports PTP (Picture Transfer Protocol) so that users can directly connect their cameras with Android device and transfer pictures with a single touch.

Android's Latest: 

Android's Latest Email: When replying or forwarding an HTML message, The Email app now sends both plain text and HTML bodies as a multi-part mime message. This ensures that the message will be formatted properly for all recipients . Enterprise support: Users can now configure an HTTP proxy for each connected Wi-Fi access point. This lets administrators work with users to set a proxy hostname, port, and any bypass sub domains .

Android Cloud to Device Messaging Framework (C2DM) : 

Android Cloud to Device Messaging Framework (C2DM) Android Cloud to Device Messaging (C2DM) is a service that helps developers send data from servers to their applications on Android devices . The service provides a simple, lightweight mechanism that servers can use to tell mobile applications to contact the server directly, to fetch updated application or user data.

Characteristics of Android Cloud to Device Messaging (C2DM) : 

Characteristics of Android Cloud to Device Messaging (C2DM ) It allows third-party application servers to send lightweight messages to their Android applications . An application on an Android device doesn’t need to be running to receive messages.

Characteristics of Android Cloud to Device Messaging (C2DM) : 

Characteristics of Android Cloud to Device Messaging (C2DM) It does not provide any built-in user interface or other handling for message data. C2DM simply passes raw message data received straight to the application. It uses an existing connection for Google services. This requires users to set up their Google account on their mobile devices.

Enabling C2DM : 

Enabling C2DM The first time the application needs to use the messaging service, it fires off a registration Intent to a C2DM server. If the registration is successful, the C2DM server broadcasts a REGISTRATION Intent which gives the application a registration ID. The application should store this ID for later use.

Enabling C2DM : 

Enabling C2DM To complete the registration, the application sends the registration ID to the application server. The application server typically stores the registration ID in a database.

Enabling C2DM The application must include the id package name is the unique identifier of our application on Android.:

Enabling C2DM Google's servers will generate a token, the registration id and return it to the application. :

Sending a Message : 

Sending a Message The application has a registration ID that allows it to receive messages for a particular device . The third-party application server has stored the registration ID . The application server sends a message to C2DM servers.

Sending a Message : 

Sending a Message Google enqueue and stores the message in case the device is inactive. When the device is online, Google sends the message to the device.

Receiving a Message : 

Receiving a Message

Receiving a Message : 

Receiving a Message The system receives the incoming message and extracts the raw key/value pairs from the message payload . The system passes the key/value pairs to the targeted Android application in a com.google.android.c2dm.intent.RECEIVE Intent as a set of extras . The Android application extracts the raw data from the RECEIVE Intent by key.
