[Aerogear-users] Issues unregistering from server

Hi everybody. I am making an android app using unified push server and Openshift. I am using the code in the next link to register my devices https://aerogear.org/docs/guides/aerogear-android/push/ the register works good and i can receive push notification. My problem is when i want to unregister the device, when i register the device and i never close the app and i unregister the device it works but my issue is when i register my device and close the app, after relaunch the app when i try to unregister the device the app brokes because of a null pointer exception in this line registrar.unregister(getApplicationContext(), new Callback<Void>() because the registar object is null I have made a lot of combinations to recover the registar object but anything works the server returns me a 404 code error. In this link is my code: https://stackoverflow.com/questions/31363464/unregister-devices-aerogear I will appreciate any help with this. -- -- View this message in context: http://aerogear-users.1116366.n5.nabble.com/Issues-unregistering-from-ser...
