Answer 1

Definitely one thing is wrong. OnReceive() is not meant to contain demanding processing that takes some time. It should be used just to notice what arrived and start corresponding actions in your Service or Activity.

Error you get is because you are trying to do something that is not possible from the BroadcastReceiver Context.

I guess you have some Activity/Service accompanied with BroadcastReceiver. So, I would recommend to move task execution to that place.
