How can I find out when on android 2.3+ a phone call starts and stops?

I need my app to find out when a phone call is taking place.

It should work on when another phone is being called and also when a call is answered. I just need my app to get notified of exactly when the connection starts and when it stops (not the dialing, ringing, etc.).

Is this somehow possible?

You can use broadcast class to achieve this as below:

public class PhoneStateBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

    TelephonyManager telephonyManager = (TelephonyManager) context
            .getSystemService(Context.TELEPHONY_SERVICE);
    telephonyManager.listen(new CustomPhoneStateListener(context),
            PhoneStateListener.LISTEN_CALL_STATE);
    }
}

class CustomPhoneStateListener extends PhoneStateListener {

    // private static final String TAG = "PhoneStateChanged";
    Context context; // Context to make Toast if required

    public CustomPhoneStateListener(Context context) {
        super();
        this.context = context;
    }

    @Override
    public void onCallStateChanged(int state, String incomingNumber) {

        super.onCallStateChanged(state, incomingNumber);
        switch (state) {

        case TelephonyManager.CALL_STATE_IDLE:
            //WHEN PHONE WILL BE IDLE       
        break;

        case TelephonyManager.CALL_STATE_OFFHOOK:
            // when Off hook i.e in call
        break;

        case TelephonyManager.CALL_STATE_RINGING:
            // when Ringing
        break;

        default:
        break;
        }
    }
}

Hope this will help you.
