Unreal Engine 4 won't let me package nor launch my game on android phone?

Unreal Engine 4 is giving me a lot of difficulties. I tried to launch the game on my phone, and the editor froze. I tried to package my game, after like 5 minutes it’ll give “package failed” and when you go to the list it says unknown error. All I want to do is just play my game and test it but I can’t.

post your build log or look though it for any errors in might say unknown error but if you look though it you will most likely see the real issue
