android - Register a broadcast receiver from a service in a new thread

Question

I have a broadcastreciever which start a long operation (uploading process). In the code of a service started from the Activity class, I need to register this receiver in a new thread.

I have checked this post Are Android's BroadcastReceivers started in a new thread? but I need a more concrete example about using Context.registerReceiver(BroadcastReceiver receiver, IntentFilter filter, String broadcastPermission, Handler scheduler)

Actually I need to know how to create a new thread from a service and to register the receiver and attached to this thread.

Thank you very much. RA

Answer 1

In your service's onCreate():

private Handler handler; // Handler for the separate Thread

HandlerThread handlerThread = new HandlerThread("MyNewThread");
handlerThread.start();
// Now get the Looper from the HandlerThread so that we can create a Handler that is attached to
//  the HandlerThread
// NOTE: This call will block until the HandlerThread gets control and initializes its Looper
Looper looper = handlerThread.getLooper();
// Create a handler for the service
handler = new Handler(looper);
// Register the broadcast receiver to run on the separate Thread
registerReceiver (myReceiver, intentFilter, broadcastPermission, handler);
