I am working on an application where i need to finish the activity from onResume if there is an incoming call. I have created a CallHelper class where i am detecting any incoming call using PhoneStateListener.

public class CallHelper {



    /**

     * Listener to detect incoming calls.

     */

    private static class CallStateListener extends PhoneStateListener {

        @Override

            public void onCallStateChanged(int state, String incomingNumber) {

            switch (state) {

                case TelephonyManager.CALL_STATE_RINGING:

                    System.out.println("RINGING");

                    OverlayActivity overlayActivity = OverlayActivity.getInstance();

                    overlayActivity.finish();

                    System.out.println("Activity has been closed!!");

                    break;

            }

        }





    }



    /**

     * Broadcast receiver to detect the outgoing calls.

     */

    public class OutgoingReceiver extends BroadcastReceiver {

        public OutgoingReceiver() {

        }



        @Override

        public void onReceive(Context context, Intent intent) {

            String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);



            Toast.makeText(ctx,

                    "Outgoing: "+number,

                    Toast.LENGTH_LONG).show();

        }



    }



    private Context ctx;

    private TelephonyManager tm;

    private CallStateListener callStateListener;



    private OutgoingReceiver outgoingReceiver;



    public CallHelper(Context ctx) {

        this.ctx = ctx;



        callStateListener = new CallStateListener();

        outgoingReceiver = new OutgoingReceiver();

    }



    /**

     * Start calls detection.

     */

    public void start() {

        tm = (TelephonyManager) ctx.getSystemService(Context.TELEPHONY_SERVICE);

        tm.listen(callStateListener, PhoneStateListener.LISTEN_CALL_STATE);



        IntentFilter intentFilter = new IntentFilter(Intent.ACTION_NEW_OUTGOING_CALL);

        ctx.registerReceiver(outgoingReceiver, intentFilter);

    }



    /**

     * Stop calls detection.

     */

    public void stop() {

        tm.listen(callStateListener, PhoneStateListener.LISTEN_NONE);

        ctx.unregisterReceiver(outgoingReceiver);

    }



}

I need to detect inside onResume, if there is any call, i need to finish the activity if not i don't need to do anything.

I haven't found the solution yet, so what i did is, i have added the code for detecting the CallStateChange inside my Activity's onResume and using that code i am executing the task which i want to execute on CallStateChange.

I am not sure if this is a correct solution or not, but would be expecting views on the same from the community.

Here's the code which i am using:

TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);



        PhoneStateListener callStateListener = new PhoneStateListener() {

            public void onCallStateChanged(int state, String incomingNumber)

            {

                if(state==TelephonyManager.CALL_STATE_RINGING){

                    // Code i wanted to execute

                }

            }

        };

        telephonyManager.listen(callStateListener,PhoneStateListener.LISTEN_CALL_STATE);
