Android 5.1 push notification icon is blank

Question

When using Parse for push notifications our app always displayed the application's launcher icon. In the latest Android 5.1 version, the icon appears to be blank (a white square).

I tried setting the icon in the meta data:

<meta-data android:name="com.parse.push.notification_icon" android:resource="@drawable/noti_icon"/>

Based on the question here

But nothing seems to work. Any ideas?

Answer 1

You must use a transparent and white icon under Android Lollipop 5.0 or greater. You can extend ParsePushBroadcastReceiver class and override the two methods to get your notification icon compatible with these Android APIs.

    @Override
protected int getSmallIconId(Context context, Intent intent) {
    return R.drawable.your_notifiation_icon;
}

@Override
protected Bitmap getLargeIcon(Context context, Intent intent) {
    return BitmapFactory.decodeResource(context.getResources(), R.drawable.your_notifiation_icon);
}

Remember to customize your code to support Lollipop and previous APIs.

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
        return BitmapFactory.decodeResource(context.getResources(), R.drawable.your_notifiation_icon_lollipop);
    }
    else{
        return BitmapFactory.decodeResource(context.getResources(), R.drawable.your_notifiation_icon);
    }

It is not related to Parse or push nitification, but just how Android 5.0 handles notification icons. See this releated question for details: Notification bar icon turns white in Android 5 Lollipop
