Hello,
I've succeeded to hook method that gives me the accelerometer events.
so now all the application which use the accelerometer are generating events.

I wanted to send all those events from the hooking method to a service using intents that will aggregate them
and write them into a sqlite db (the db is not relevant for now, only the service).
The problem is that i can't start the intentService from the hook method.

Things that i tried already:
-- getting the Context from the activity on load by hooking the onStart in the Activity.class (succeeded getting the context but not starting the Service with an intent)

-- using the same context as above but start a broadcast receiver with implicit intent (define intent-filter in the manifest), and from the
broadcast to start the service (not worked either, the broadcast never got the sent message)

is there some guide or tutorial that can show me how to start a service or broadcast receiver from the hook method?
thanks ahead...
