应用程序重新启动，同时更新Firebase数据库中的数据

标签： java android firebase firebase-realtime-database

当我尝试通过此代码在Firebase数据库中添加/更新数据时，我的应用ui会冻结，并且应用会在3-5秒后重新启动。

    FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
    String username = findViewById(R.id.editText).getText().toString();
    DatabaseReference reference = FirebaseDatabase.getInstance().getReference().child("Users").child(username);
    Map map = new HashMap();
    map.put("name",user.getDisplayName());
    map.put("userID",user.getUid());
    map.put("photoUrl",user.getPhotoUrl());
    reference.setValue(map).addOnCompleteListener(new OnCompleteListener() {
                @Override
                public void onComplete(@NonNull Task task) {
                    if(task.isSuccessful()){
                        Toast.makeText(context,"Ready to go",Toast.LENGTH_SHORT).show();
                    }else{
                        Toast.makeText(context,"Something went wrong",Toast.LENGTH_SHORT).show();
                    }
                }
            });

logcat中什么都没有，但是当我将其设置为no-filter时 这件事在logcat中不断重复，直到我从最近的apps中手动关闭了app。我能够从firebase数据库中读取，但无法写入。 firebase实时数据库规则设置为测试模式
