If anyone else has issues with Intel XDK, here is what worked for me:
Dont use the normal Android build function, only use Crosswalk
If you get an error on Android (cant install application), make sure you ticked Sign application.
No need to tick "media" to play sounds
If you are using AdMob, make sure "Admob plugin" is ticked
Only tick "device" in the left side panel, not device in the right panel
