Embedded System

Android  is a software stack for mobile devices created by the Google lead Open Handset Alliance  .It  includes an OS ( Linux ) , middleware, core  applications. It is device independent  platform  . You can develop  applications  for devices such as mobile phone, Tablet  PC, notebook, GPS device, Reader, Set Top Box, TV. Android applications  are developed  in Java. Android also uses XML to define various resources inside the application. Google provide Android software development kit  (SDK) .It is free and includes  compiler, debugger, device emulator, Java virtual machine (Dalvic virtual machine ). Android supports 2D and 3D  graphics using the OpenGL libraries. Data storage with open source database SQLite. Android allows  programmers to add any application of their  choice on an actual platform.

Introduction to Android Actually android itself is not an Operating System, Inner level OS is Linux,over the linux Android is loading. Android is devoloped by Google , so google provide core libraries. It is a java oriented platform for devoloping and excecuting mobile applications. We can write programs in java and utilise android classes and API's. Applications and libraries mainly concentrated in mobile devices. Android applications can excecute in mobile device  with Android platform.   ipod  TabletPC  PDA  Embedded System ( Dedicated special purpose System) In embedded field lot of limitations for Android devolopment. Direct access to H/W is difficult in application level. We have to write driver programs for accessing H/W ( GPIO-general purpose I/O). After modifiying the Source Code and including the driver , recompile the OS and create image.     For biginning the Android development the following packages are...
