一部のデバイスでAndroidアプリが動作しない

Question

firebaseの子を表示するアプリを作成しました。私の電話（ネクサス6）で働いていて、別のもの（1 + 3）で動作しますが、私がredmi note 3のような他のデバイスにそれをインストールしたとき、アプリの強制は終了します。なぜこれが起こっているのか分かりません。

Logcat：私は昨日のボタンを削除し、ImageViews

で更新していたとして、ここでは

Answer 1

は時々、問題は、彼らが割り当てられたIDとプロジェクトのニーズの混乱を作るのIDEで発生し、再構築きれいでも、キャッシュを無効にし、いくつかのケースで再起動する必要があります。この場合も同様に、コードはok、clean、re-buildのように見え、Xiaomiで再度アプリケーションを実行します。
