Question

I created one sample phone app just dial a entered number like ” Intent callIntent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:"[phone]);” able to call the dialed number.

I have create one service to get the phone state [Ringing or idle or offhook]. Am able to receive the proper state.

Now i need to differentiate the incoming call is dialed from device phone application or using my sample phone application. How can i achieve this ?

I tried with “intent.putExtra("CALL_KEY", "CALL_VALUE");” but am unable to receive a value :

intent.getStringExtra("CALL_KEY");
Bundle bundle = intent.getExtras();
bundle.getString("CALL_KEY");

Both returns the NULL value.

Please help me to identify in my service the phone call is made from my sample app or from default phone app ?

My Query similar to this :

Android: Can you send/receive data along a phonecall?

I find the one way to send the information to the other device , but still am finding difficulty to receive the data.

Tried with extractNetworkPortion and extractPostDialPortion , but still getting NULL at receiver end.

Help me ! How can i receive data along with a phonecall ?
