Blank Notification Issue

[ummerakbar45]

Hi

As per documentation we can track uninstall number with the help of Appsfyer by adding below line of code inside onNewToken method of firebase service class:
AppsFlyerLib.getInstance().updateServerUninstallToken(getApplicationContext(), token);

But we got issue with this code, this code created blank notification .

Here is my firebase service file
public class FirebaseService extends FirebaseMessagingService implements NetworkInterface{
private static final String TAG = "firebaseService";
private APIRequests apiRequests;

/**
 * Called if InstanceID token is updated. This may occur if the security of
 * the previous token had been compromised. Note that this is called when the InstanceID token
 * is initially generated so this is where you would retrieve the token.
 */
@Override
public void onNewToken(String token) {
    Log.d(TAG, "Refreshed token: " + token);
    AppsFlyerLib.getInstance().updateServerUninstallToken(getApplicationContext(), token);
   // sendFirebaseTokenToServer(token);

}
