    I can actually launch the project to my phone, but i cannot package apk file. Or if i try to package without "enable gradle instead of ant" its works but AR camera not working. Also i use "package game inside apk" because if i uncheck it i will get "No Google Play Store Key" error. I try to fix this two days but it does not work out. I try to spawn large blueprint with many static meshes, materials. If some one know the solution please wright comment.
