11. 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
11

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!
