I created a service (service B) from Activity (Activity A). And from service B, i created another service (service C). previously the service C used to be a thread not a service. Since it has problems in the long run i changed it to a service. The service C runs a while loop with 3 second Thread.sleep calls. But general condition it do not stop. The Log shows the service is running. But the UI is blocked and after few mins system ask me whether to shut down.
How to make this service non blocking call?
From the service documentation in Android
A Service is not a separate process. The Service object itself does not imply it is running in its own process; unless otherwise specified, it runs in the same process as the application it is part of.
A Service is not a thread. It is not a means itself to do work off of the main thread (to avoid Application Not Responding errors).
The best way in this case is to start a new thread and then call a service from there.
