Dalvik Virtual Machine & DEX Bytecode

Are you interested in Dalvik virtual machine and/or DEX bytecode? As you may know, Android application is eventually compiled into DEX bytecodes running on Dalvik virtual machine. 

Here are several interesting starting points you must know particularly if you like to hack Android applications.
