You can do this in Two ways:

1) Use a LocalBroadcastManager and write a receiver for sending and receiving the Broadcasts within the application (Might be heavy and complex, so not expanding the details, but works).

2) Use Message passing using Handler (This is Simple).

• Create a Handler in Main Activity and pass its reference to Service
• Send a Empty Message using the Activity handler with respective event ID and update the UI accordingly in the Activity.
• Refer to this Example. - This user TimerTask and Runnables but for your pupose just send empty Message using the Handler and handle them in handleMessage(Message msg) call back of Handler.
