Did you get the same error I did? The path listed was emulated/0/system/apps or something like that, so it was trying to write into system/apps and it was an invalid directory... I just figured I had the emulated storage bug and I needed to wipe it so I installed regular gapps
also, does the kb still crash on 10.1? I had to put a seperate keyboard...
Not sure I recall seeing an error just never installed. Got to do a wipe Ill check it again tonight. As for keyboard, I have used the thumb keyboard since I first got it.
