Hello,
I am using odoo-rpc-v2.aar in my android App for XML rpc calls. 

Now I need to Implement  FCM (FireBase Cloud Messaging) for Push notification. 
When my App receiving a notification  it Crashes. The error I get

FATAL EXCEPTION: IntentService[ActionHandlerService] 

java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference 

And I found that the class ActionHandlerService is from XML rpc lib.

So, please let me know how I can solve this issue or

Please Guide me if the notification related classes are already in XML rpc lib How can I use them.

I would appreciate any kind of help.

Thanks
Jogendra
