アプリとサーバーに GCM メッセージングを実装しましたが、すべて正常に動作しますが、すべての電話では機能しません!
主な問題は次のとおりです。
アプリを開くとGCMメッセージが表示され、想定どおりに通知が生成されますが、アプリを閉じると、(LOGCATを介して)メッセージが受信されたがキャンセルされたことがわかります->「ブロードキャストレシーバー、結果=キャンセル」。
次に、アプリ サービスをバックグラウンドで動作させることができません。「最近のアクティビティ」メニューからアプリを「閉じる」限り、バックグラウンドでも停止します（設定->アプリ->「MY_APP」->強制停止は無効になっています）。
多くの調査を行った結果、「最近のアクティビティ」タブからアプリをスワイプすると、Huawei P8 (主要なテスト デバイス) がすべてのアプリを自動的に強制終了することが原因であると考えられます。しかし、そうすると、「Facebook」や「Viber」などの他のアプリからプッシュ通知が送られてきません。

私は混乱しています！原因の根本を見つけることができません。
前もって感謝します。
