i would like to give you idea on this, you need to listen to Broadcast Intent (type here would be 'Call ') . when you find this intent is broadcasted ( write down code which opens your app) .
I had write in manifest.xml to register broad cast receiver as
in MyReceiver class I write as
and in my MicroERS I have
but when I call on any number then it will not send message. What is wrong in my code.
