I am having a strange error with notification manager.

@Override
public void onMessageReceived(String from, Bundle data)
{
     Log.i(TAG, "IP : " + (String) data.get("ip"));
     NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
     Intent acceptNextIntent = new Intent(MainActivity.BROADCAST_KEY_ACCEPT);
//        acceptNextIntent.putExtra("ip", (String) data.get("blah")); //add stuff here
     PendingIntent acceptNextPendingIntent = PendingIntent.getBroadcast(this, 0, acceptNextIntent, 0);

     Intent declineNextIntent = new Intent(MainActivity.BROADCAST_KEY_DECLINE);
     PendingIntent declineNextPendingIntent = PendingIntent.getBroadcast(this, 0, declineNextIntent, 0);

     NotificationCompat.Action acceptAction = new NotificationCompat.Action
                .Builder(R.drawable.common_signin_btn_icon_disabled_focus_light, "Grant Request", acceptNextPendingIntent).build();

     NotificationCompat.Action declineAction = new NotificationCompat.Action
                .Builder(R.drawable.common_signin_btn_icon_focus_dark, "Decline Request", declineNextPendingIntent).build();

     NotificationCompat.Builder notification = new NotificationCompat.Builder(this)
                .setContentTitle("New Password Request From " + (String) data.get("ip"))
                .addAction(acceptAction)
                .addAction(declineAction);

     notificationManager.notify(1, notification.build()); //ERROR HERE

Does this mean that the icons I am trying to access does not exist? I am not sure how to interpret this error and searching this error message does not yield anything.

You're actually not setting an icon for the push notification. Add .setSmallIcon(R.drawable.your_icon) to your notification.

 NotificationCompat.Builder notification = new NotificationCompat.Builder(this)
            .setContentTitle("New Password Request From " + (String) data.get("ip"))
            .setSmallIcon(R.drawable.your_icon)
            .addAction(acceptAction)
            .addAction(declineAction);

You have not called setSmallIcon() on the NotificationCompat.Builder. This provides the icon that will go in the status bar while the Notification is active.

According to the Android NotificationManager Source Code

if (mContext.getApplicationInfo().targetSdkVersion > Build.VERSION_CODES.LOLLIPOP_MR1) {
    if (notification.getSmallIcon() == null) {
        throw new IllegalArgumentException("Invalid notification (no valid small icon): "
                + notification);
    }
}

This error only happened when you set target API > LOLLIPOP_MR1(22) and notification do not have a small icon.

This suddenly started happening to my application. After some research, I found this change in my manifest file actually started causing it.

from:

  <uses-sdk android:minSdkVersion="21" />

to:

  <uses-sdk android:minSdkVersion="21" android:targetSdkVersion="28" />

I saw somewhere that somebody noted that it only checks for the icon if the target sdk version is set. Sure enough, in the source, there is this :

if (mContext.getApplicationInfo().targetSdkVersion > Build.VERSION_CODES.LOLLIPOP_MR1) {
    if (notification.getSmallIcon() == null) {
        throw new IllegalArgumentException("Invalid notification (no valid small icon): "
                + notification);
    }
}

Luckily, the solution was simple, just define the icon in the manifest:

  <application android:label="MyApp" android:icon="@mipmap/icon" >
