Mobile packaging problem in ue4.9.2

Hello
I have been having a problem packaging my project to mobile in ue 4.9.2. Every time i package and i move it to my mobile or test it on genymotion it installs but never actually works and crashes on start up. So i decided to download the swing ninja project and test to see if it was a problem with my project but after successfully packaging swing ninja the same thing happened i really dont know what to do since there is deadline to submit my app and i really need help.

Can you provide any logging that might indicate what is happening?
