このコードを使用してfirebaseデータベースのデータを追加/更新しようとすると、アプリのUIがフリーズし、3〜5秒後にアプリが再起動します。
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には何もありませんでしたが、フィルターなしに設定すると、最近のアプリから手動でアプリを閉じるまで、このことがlogcatで繰り返されます.firebaseデータベースから読み取ることはできますが、書き込むことができません。firebaseリアルタイムデータベースルールがテストモードに設定されている
