I realize that this is not possible since Android doesnt have a JVM but is there a work around to this problem? I need to perform a byte code injection operation for an Android application. Any suggestions?
You can't directly inject bytecode into already loaded classes/methods. However, you can dynamically create new classes, write them to a dex file, and then dynamically load them
See this blog post for more information on dynamic loading of classes from a dex file on disk.
In order to dynamically create a new dex file, you might look at using the dexlib component that is part of the smali/baksmali codebase, which is a general purpose library for reading/writing dex files.
Or, alternatively, you could include smali in your application and generate your classes in the smali assembly format and use smali directly to assemble them into a new dex file.
