Permission In Calling Service From Another App

Possible Duplicates: Permission for services, Permission issue while starting a service from android, Exported service does not require permission: what does it mean?, Not allow

Solution 1:

I think you're missing the permission declaration in App manifest A.

http://developer.android.com/guide/topics/security/permissions.html See Declaring and Enforcing permissions.

Also, if both the apps are signed and authored by you (with the same signature) you can declare them in both manifests so that the order in which they are installed doesn't affect this.

Ideally the permission name should be .permission.
