Question

Unable to start service . Line is added in onCreate of service.

<pre>ServiceManager.addService(ACTION_REMOTE_SERVICE, (IBinder) new xxxRemoteservice(this));</pre>

Changes we removed android:sharedUserId="android.uid.system" from manifest . But the application is signed with platform certificate And LOCAL_VENDOR_MODULE := true

Getting error below
