如何将其他服务（从带有通知的警报开始）发送到MainActivity？

Question

My MainActivity has Alarm . Alarm starts to repeat Service and send data to it from intent.putExtra from pendingIntent . When Service returns true, then it autocanсels itself (by new pendingIntent -> cancel) and sends data to Notification (if the user clicks on it, the app will start with new data from that Notification or the user only starts app -> it will load with new data). I need to send my putExtras from Notification to MainActivity , getExtra in MainActivity , and (if that is possible) commit it automatically.

If I'm right, i must use startActivityForResult before calling Service , but how can I do this with Alarm ?

PS already work all except for that step " Notification.putExtras() -> MainActivity.getExtras() .

I think that what you are looking for are Bound Services .

A bound service is an implementation of the Service class that allows other applications to bind to it and interact with it.

Take a look at this and let me know if it helped. Here they talk about the alternatives to communicate between service and activities: servicecommunication .
