  29. 29. Architecture – Runtime Libraries Android runtime contains the following modules: •Core Libraries – Core Android Libraries are different from JavaSE & JavaME libraries. However these libraries provide most of the functionalities defined in the Java SE libraries. •Dalvik Virtual Machine(DVM) – Optimized for low processing power and low memory environments. It runs .dex files, which provides higher efficiency in low resource environments. The Dalvik VM allows multiple instance of VM to be created simultaneously providing security, isolation, memory management and threading support.
  30. 30. Architecture – Appln Framework Application framework consists of following modules : •Activity Manager: Manages the activity life cycle of applications •Content Providers: Manage the data sharing between applications •Telephony Manager: Manages all voice calls •Location Manager: Location management, using GPS / A-GPS •Resource Manager: Manage the different types of resources we use in our applications

  33. 33. ADT – Native Development Kit(NDK) •Libraries written in C/C++ can be compiled to x86 native code and installed using the Android Native Development Kit (NDK) NDK is based on command-line tools and requires invoking them manually to build, deploy and debug the apps.oracle training in chennai •Native classes can be called from Java code running under the Dalvik VM using the System.loadLibrary() call, which is part of the standard Android Java classes •Several third-party tools allow integration of NDK with Eclipse and Visual Studio
  34. 34. Web/GUI based ADTs App Inventor for Android •A web based visual development environment for novice programmers •It is based on MIT's Open Blocks Java library •This is a drag and drop model GUI application developer for Android •This development kit can be accessed online at http://appinventor.mit.edu/ Basic4Android •Inspired by Visual Basic and Visual Studio •Commercial Android Development Product •Strong community of developers
