here my output log i m in development buildlink text
Hello ,
It looks like there are a lot of errors in this log dealing with Android and Google Play. Can you attempt packaging for Windows to see if we can isolate some of these errors? Also, can you make sure that you Android Works is up to date? After all of that, try opening a blank project and packaging it for Android to see if you get the same errors.
We haven’t heard from you in a while, . Are you still experiencing this issue? If so, please refer to my last comment for the information I need to proceed in helping you. In the meantime, I’ll be marking this issue as resolved for tracking purposes.
problem comes from apk level i tryed to package my game with google vr before days i can package my game to android 19 and play in my phone but i don’t know that change but unreal asks android 21 for google vr when i do package 21 it succesfull i will be more happy if its just package to android 19 
Android 21 is required for using the Google VR plugin, unfortunately you won’t be able to use 19 with it enabled. You can find more information setup for Google VR at this link: https://docs.unrealengine.com/latest/INT/Platforms/GoogleVR/QuickStart/2/index.html
Then how did i open in my android 19 phone before? is there any way to play vr in android 19 or this option removed?
After looking into it further, it seems that Android 19 is fine for Google VR on its own, but 21 is required if you’re using the Android N plugin. Are you using this plugin as well?
