I've managed to get notifications working in older API's, but not Oreo. Creating the notification causes my app to still work fine (no messages in logcat), however SystemUI crashes and reboots in an endless cycle while the Activity is running. The is the error in logcat for the systemui process:
java.lang.IllegalArgumentException: width and height must be > 0
My code:
private void showPlayingNotification() {
NotificationCompat.Builder builder = mNotificationUtils.getAndroidChannelNotification(this, "Play", mMediaSessionCompat);
if( builder == null ) {
Log.i("Play Notification","No notification found!");
return;
}
mNotificationUtils.getManager().notify(101,builder.build());
}
I initialised mNotificationUtils in the onCreate of the MediaPlayerService I created.
public class NotificationUtils extends ContextWrapper {
private NotificationManager mManager;
public static final String AUDIO_CHANNEL_ID = "com.liftyourheads.dailyreadings.dailyReadingsAudio";
public static final String AUDIO_CHANNEL_NAME = "Daily Readings Audio Stream";
public NotificationUtils(Context base) {
super(base);
createChannels();
}
public void createChannels() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
// create android channel
NotificationChannel dailyReadingsAudioChannel = new NotificationChannel(AUDIO_CHANNEL_ID,
AUDIO_CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
getManager().createNotificationChannel(dailyReadingsAudioChannel);
}
}
public NotificationManager getManager() {
if (mManager == null) {
mManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
}
return mManager;
}
public NotificationCompat.Builder getAndroidChannelNotification(Context context, String action, MediaSessionCompat mediaSession) {
if (action.equals("Play")) {
return MediaStyleHelper.from(context, mediaSession)
.addAction(new NotificationCompat.Action(android.R.drawable.ic_media_pause, "Pause", MediaButtonReceiver.buildMediaButtonPendingIntent(this, PlaybackStateCompat.ACTION_PLAY_PAUSE)))
.setStyle(
new android.support.v4.media.app.NotificationCompat.MediaStyle()
.setShowActionsInCompactView(0)
.setMediaSession(mediaSession.getSessionToken()))
.setSmallIcon(R.mipmap.ic_launcher)
.setContentText("Content Text")
.setContentTitle("Content Title")
.setChannelId(AUDIO_CHANNEL_ID);
} else if (action.equals("Pause")) {
return MediaStyleHelper.from(context, mediaSession)
.addAction(new NotificationCompat.Action(android.R.drawable.ic_media_play, "Play", MediaButtonReceiver.buildMediaButtonPendingIntent(this, PlaybackStateCompat.ACTION_PLAY_PAUSE)))
.setStyle(
new android.support.v4.media.app.NotificationCompat.MediaStyle()
.setShowActionsInCompactView(0)
.setMediaSession(mediaSession.getSessionToken()))
.setSmallIcon(R.mipmap.ic_launcher)
.setContentText("Content Text")
.setContentTitle("Content Title")
.setChannelId(AUDIO_CHANNEL_ID);
}
return null;
} }
