Ajay,
The LOCAL appID should work to start and stop your application. Since you did a local install, and not from DeviceHQ, your app was assigned the appId of LOCAL. Currently, the way app-manager works, it was intended to only manage one LOCAL app at a time, so if you install a second, you may not get the behavior you want.
In my example, the application was installed by downloading it from DeviceHQ.
