Development Environment or Emulator

Hi,

I have started designing a skin of my own for Kodi but in order to test anything I have to copy files over to my device and reload skin for every little thing which makes the process quite time consuming. I have tried several android emulators but Kodi either crashes at every corner or the emulator only uses android 4.4 which makes Kodi unavailable.

Is there any working emulator out there for use with this or any other trick to make testing changes a bit faster ?

Thanks..
