Android Layers Linux kernel provides drivers for the Android hardware,

networking, file system access & inter-process-communication

Libraries are mostly written in C or C++

Core Libraries are the core development kit including utility, i.o. etc

Dalvik Virtual Machine is an optimized Java VM

Application Framework is the API to developers

Applications are user facing programs

12

Android Applications

• Each application runs in its own process, gets unique identifier & runs its own instance of Dalvik VM

This way the processes are isolated & crash of one application does not bring down the whole system!
