This issue occurs on low-end Android devices that kill the Activity when your app is backgrounded during the authentication process. We persist values in private instance fields so we can read/use them during the code/token exchange in our onActivityResult handler. We end up getting a null pointer exception because these values don’t exist when we go to read them. Notice the first line in the posted stack trace

java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.Boolean.booleanValue()' on a null object reference
    at com.rnappauth.RNAppAuthModule.onActivityResult(RNAppAuthModule.java:419)

I’ve talked with the other maintainers and we are going to try to get around to a fix for this. I can’t provide a timeline, but just a heads up that it’s on our radar. There are a few issues in the repo where this is the root cause.
