    text
    copied!<p>I have a Media service that uses startForeground() to show a notification when playback starts. It has pause/stop buttons when playing, play/stop buttons while paused.</p> <pre><code>NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this); // setup... Notification n = mBuilder.build(); if (state == State.Playing) { startForeground(mId, n); } else { stopForeground(false); mNotificationManager.notify(mId, n); } </code></pre> <p>The problem here is when I show/update the notification in it's paused state, you should be allowed to remove it. <code>mBuilder.setOngoing(false)</code> appears to have no effect as the previous <code>startForeground</code> overrides it.</p> <p>Calling <code>stopForeground(true);</code> with the same code works as expected, but the Notification flashes as it is destroyed and recreated. Is there a way to "update" the notification created from startForeground to allow it to be removed after calling stop?</p> <p><strong>Edit:</strong> As requested, here's the full code creating the notification. createNotification is called whenever the service is played or paused.</p> <pre><code>private void createNotification() { NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_launcher) .setContentTitle("No Agenda") .setContentText("Live stream"); if (android.os.Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.JELLY_BEAN) { if (state == State.Playing) { Intent pauseIntent = new Intent(this, MusicService.class); pauseIntent.setAction(ACTION_PAUSE); PendingIntent pausePendingIntent = PendingIntent.getService(MusicService.this, 0, pauseIntent, 0); mBuilder.addAction(R.drawable.pause, "Pause", pausePendingIntent); //mBuilder.setOngoing(true); } else if (state == State.Paused) { Intent pauseIntent = new Intent(this, MusicService.class); pauseIntent.setAction(ACTION_PAUSE); PendingIntent pausePendingIntent = PendingIntent.getService(MusicService.this, 0, pauseIntent, 0); mBuilder.addAction(R.drawable.play, "Play", pausePendingIntent); mBuilder.setOngoing(false); } Intent stopIntent = new Intent(this, MusicService.class); stopIntent.setAction(ACTION_STOP); PendingIntent stopPendingIntent = PendingIntent.getService(MusicService.this, 0, stopIntent, 0); setNotificationPendingIntent(mBuilder); mBuilder.addAction(R.drawable.stop, "Stop", stopPendingIntent); } else { Intent resultIntent = new Intent(this, MainActivity.class); PendingIntent intent = PendingIntent.getActivity(this, 0, resultIntent, 0); mBuilder.setContentIntent(intent); } Notification n = mBuilder.build(); if (state == State.Playing) { startForeground(mId, n); } else { stopForeground(true); mNotificationManager.notify(mId, n); } } @TargetApi(Build.VERSION_CODES.JELLY_BEAN) private void setNotificationPendingIntent(NotificationCompat.Builder mBuilder) { Intent resultIntent = new Intent(this, MainActivity.class); TaskStackBuilder stackBuilder = TaskStackBuilder.create(this); stackBuilder.addParentStack(MainActivity.class); stackBuilder.addNextIntent(resultIntent); PendingIntent resultPendingIntent = stackBuilder.getPendingIntent( 0, PendingIntent.FLAG_UPDATE_CURRENT ); mBuilder.setContentIntent(resultPendingIntent); } </code></pre> <p><strong>Follow-up Edit:</strong></p> <p>One of the comments below mentioned that the answer may be "fragile", and as of the release of Android 4.3, the behavior behind <code>startForeground</code> has changed. startForeground will force your application to show a notification while in the foreground, and the method should just be called with the notification to show. I haven't tested, but the accepted answer may no longer work as intended.</p> <p>In terms of stopping the flashing when calling <code>stopForeground</code>, I don't think it's worth fighting the framework for.</p> <p>There's some <a href="http://www.androidpolice.com/2013/07/29/android-engineer-explains-why-some-apps-suddenly-have-persistent-notifications-after-you-upgrade-to-android-4-3/" rel="noreferrer">additional information on the Android 4.3 notification change here</a>.</p>
