Android Fixes

* Fixed issue where title was not settable in the last version.
* Fixed rare bug where device would not register as unsubscribed when only part of Google play services was included which was making the issue harder to debug.
* Removed logcat extra warnings from looperj that can be safely ignored, fixed error from showing in the logcat when your app is reinstalled.
