iam trying to run an activity from diffrent package from my remote service: this is how i implement the service.java

You shouldn't call start activity from your service. From Android developers best practice:
Instead of spawning Activity UIs directly from the background, you should instead use the NotificationManager to set Notifications. These will appear in the status bar, and the user can then click on them at his leisure, to see what your application has to show him.
