【Android】Push通知タップ後にActivityが起動しない場合の対処法

More than 3 years have passed since last update.

概要

同じアプリ内で複数のPendingIntentを使っている(NotificationやWidgetを実装している)場合に、Push通知タップ後にActivityが起動しないときの対処法メモです。

結論

PendingIntent.getActivity()の第二引数をユニークな値にする。

以下のように第二引数を固定値にしているとActivityが起動しない場合があります。

PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

その場合は以下のようにユニークな値に変更すると解決します。

PendingIntent pendingIntent = PendingIntent.getActivity(context, uniqueId, intent, PendingIntent.FLAG_UPDATE_CURRENT);
