Notifications Error Android 11

"Notifications in Night Clock don't display the correct icon, instead of showing whatever icon appears in the actual notification it just shows an i in a circle icon. In the attached screenshot the notification was for Gmail which has an envelope icon."

Seems to be a problem with "Alerting notifications" (German: "Erinnerungsbenachrichtigung")
-> No Problem with Android 9

Probably we have to switch to another method to retrieve the drawables. The current code is quite old. We could use api level M yet. Nowadays almost everybody has at least M.

@RequiresApi(api = Build.VERSION_CODES.M)
private Drawable getSmallIcon(Context context, StatusBarNotification sbn) {
    Notification notification = sbn.getNotification();
    Icon icon = notification.getSmallIcon();
    return icon.loadDrawable(context);
}

We also have to find a solution for "BrowseNotificationApps":
try {
ai = pm.getApplicationInfo(app.getPackageName(), 0);
if (ai != null) {
holder.appicon.setImageDrawable(pm.getApplicationIcon(ai));
}
} catch (PackageManager.NameNotFoundException ex) {
Log.e(TAG, "Appicon not found. ", ex);
holder.appicon.setImageResource(R.mipmap.ic_launcher);
}
