单击 AlertDialog 的肯定按钮获得 'E/AndroidRuntime: Error reporting crash android.os.TransactionTooLargeException'

Question

我收到此错误：

E/AndroidRuntime: Error reporting crash android.os.TransactionTooLargeException

还有这个：

java.lang.WhosebugError: stack size 8MB

而运行下面给出的代码：

    mAuthListener = new FirebaseAuth.AuthStateListener() {
                @Override
                public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                    final FirebaseUser user = firebaseAuth.getCurrentUser();
                    if (user != null) {
                        // User is signed in

                        if (isFacebookLoggedIn()) {

                                usernameWarning.setVisibility(View.INVISIBLE);

                                builder.setTitle("Choose a unique username");

                }
            };

我以前从未见过任何此类错误，这就是为什么我不知道这里发生了什么。

请告诉我是什么导致了这个错误！

Answer 1

您正在为节点 mDatabase.child("unique-usernames") 添加侦听器。然后在该侦听器的 onDataChange() 回调中，您正在修改同一节点的子节点：

mDatabase.child("unique-usernames").child(ts).setValue(uniqueUserName.getText().toString());

这会导致侦听器回调再次触发，从而导致死循环。

Answer 2

深入研究代码至少 10-12 次后，我发现了这里的问题。

解决方案是在这行代码中添加 .toString() 和 user.getPhotoUrl()：mDatabase.child("users").child(user.getUid()).child("imageUID").setValue(user.getPhotoUrl());

这个回答 gave me a bit hint. Thanks qbix。

那么，现在已经解决了！
