Why there isn't a simpler way to stop an activity from another?

Question

I know there are many topics about this, and I understand (or at least I think I do) the Activity lifecycle. I know the Activity itself should handle its lifecycle, including the process of stopping the Activity.

But, in some cases, this is just not practical, for example, if you have a controller, to manage your interface, and maybe receiving I/O results.

So, wouldn't be nice just to send some Intent with an action like a ACTION_STOP_REQUEST, and let the Activity handle it?

Answer 1

So, wouldn't be nice just to send some Intent with an action like a WHATEVER, and let the Activity handle it?

AFAIK, that's what BroadcastReceivers are for.

Answer 2

As Cristian suggested, use BroadcastReceiver

You could include private BroadcastReceivers in each Activity that you would want to respond to the ACTION_STOP_REQUEST and have them call finish() in onReceive()
