I'm getting this error:
E/AndroidRuntime: Error reporting crash android.os.TransactionTooLargeException
and this too:
java.lang.StackOverflowError: stack size 8MB
while running below given code:
mAuthListener = new FirebaseAuth.AuthStateListener() {

I have never seen any such error before and that's why I have no idea what's happening here.
Please let me know what is causing this error!
回答1:
After looking deeply into code at least 10-12 times, I got the problem here.
The solution was to add .toString() with user.getPhotoUrl() in this line of code: mDatabase.child("users").child(user.getUid()).child("imageUID").setValue(user.getPhotoUrl());
This answer here gave me a bit hint. Thanks qbix.
So, it has been solved now!
回答2:
You are adding a listener for node mDatabase.child("unique-usernames"). Then in the onDataChange() callback for that listener, you are modifying a child of that same node:
mDatabase.child("unique-usernames").child(ts).setValue(uniqueUserName.getText().toString());
This causes the listener callback to fire again, resulting in an endless loop.
