Why am i getting an Error: Error Launch Failed when I package for android

Here is the log info here. Also just to Make a note I tested the android packaging on the default blueprint 3rd person game and it worked perfectly. I sent the game to my Asus Zenpad with Nougat OS.

I am using Blueprints
Ive install visual studio 2015
Now using unreal v4.15.2

Hello,

The error message at the bottom of your log is a generic one and the actual error is elsewhere. Please refer to the Packaging and Deployment Troubleshooting guide for more information on what you may be able to do to fix your issue and what information you may need to provide.

Hey Mathew Thank after your response i went back and looked at the error closely.
Under the Preparing to make APK I figured it out. I didn’t have the correct sdk APk build loaded for my tablet. Default was android 19, I needed to install Android 21 and 23. that fixed it.
Now on to the next problem of trying to figure out why the left virtual joystick works(moves left, right, forward and back) but not the right(camera movement or rotation control)
