Androidでプッシュ通知を実装しています。この問題は、通知を更新したいときに発生します。私は、通知を表示する場合、私は単にそれを更新し、これを行うように通知を積み重ねたいと思います。プッシュ通知の更新Android
mNotifyBuilder.setContentText(currentText)
.setNumber(++numMessages);
しかし、通知を受け取るたびに、++ numMessagesは合計される前に0に設定されます。画面に通知があれば、それが残っていた場所から要約する必要があります。あなたはサービスがメモリを解放するOSによって殺されている可能性がありますので、あなたのフィールド値が、onMessageReceivedに複数の呼び出しにわたって持続する期待すべきではありません、一般的には
