Every Android application runs in its own process, with its own instance of the Dalvik virtual machine. Dalvik has been written to the device can run multiple VMs efficiently. The virtual machine runs Dalvik Dalvik executable files (. Des) format optimized for minimum memory.
VM is register-based, and runs classes compiled by a Java compiler that has transformed him as the DEX format understood by the "DX" tool. Dalvik virtual machine depends on the Linux kernel for underlying functionality such as memory management, threading and low.
Android is based on Linux version 2.6 for basic services such as system security, stack memory management, process management, and network and the controller model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack.
For example, an Android application developer (http://www.zaptechsolutions.com/
