    I should also point out that Android 5.0 switched from Dalvik to the
    Android Runtime.<br>
    When an app is installed now, the Dalvik bytecode is compiled to
    native ARM, MIPS, or x86 code.<br>
    I haven't looked into this process much. PANDA has trouble with
    Android 5 because of the graphical effects rendering.<br>
    In my experience, the Android emulator has similar issues unless
    using the host GPU for OpenGL acceleration is enabled.<br>

      That's correct. The last time I looked at DroidScope, it could
      introspect on Dalvik in Android 2.3, running on a 32-bit host.<br>
      The DroidScope code we included as the linux_vmi plugin doesn't
      have Dalvik-layer introspection enabled, since it's 1) obsolete,
      and 2) requires a 32-bit executable. The process, thread, module,
      and symbol tracking are still enabled, but won't help with
      Java/Dalvik code. <br>
      <br>
      Android 2.x's interpreter had a function that was run on each
      opcode, so DroidScope's symbol-parsing was enough to bootstrap a
      Dalvik-instruction callback point. The interpreter in 4.0 was
      rewritten for performance, and doesn't have an analogous function,
      as far as I know.<br>
      <br>
      I know DroidScope has documentation about Android 4.3, but there
      doesn't seem to be any code for it. There haven't been any commits
      to it for over two years.<br>
