从Google Play下载后，应用首次启动时会崩溃（ExceptionInInitializerError）

Question

RN 0.55.4
Gradle: 2.2.3 

There is one issue on Android. We updated some node_modules and react native to version 0.55 and everything looks ok but when we release this new version into google beta and then we download it for testing the app always crash at first run. And we run it once again and everything is ok app works fine. And we have no idea whats wrong Errors what we get from fabric.io and its happen only once when we download that app from play.

and this happened too at same time

Fatal Exception: java.lang.RuntimeException: Unable to start receiver tv.dailyme.android.core.receiver.Autostart: java.lang.NullPointerException: Attempt to invoke virtual method 'android.database.sqlite.SQLiteDatabase android.content.Context.openOrCreateDatabase(java.lang.String, int, android.database.sqlite.SQLiteDatabase$CursorFactory, android.database.DatabaseErrorHandler)' on a null object reference

I think there is something wrong in our gradle settings

Fatal Exception: java.lang.RuntimeException: Unable to start receiver tv.dailyme.android.core.receiver.Autostart: java.lang. NullPointerException :

Attempt to invoke virtual method 'android.database.sqlite.SQLiteDatabase android.content.Context. openOrCreateDatabase (java.lang.String, int, android.database.sqlite.SQLiteDatabase$CursorFactory, android.database.DatabaseErrorHandler)'

on a null object reference

it appears, as if your ProGuard configuration might not suffice not to obfuscate something.

you could add a != null check into class tv.dailyme.android.core.receiver.Autostart , in order to at least not produce throw that NPE . improving the ProGuard -keep rules seems required.
