Handling Incoming Calls In Android

I want to handle incoming call in Android. Actually I want to set a time duration in which if my cell phone receive any call then automatically a message send to each of them. Any

Solution 1:

Just extend your class to PhoneStateListener and override onCallStateChanged method. Sample code:

classmyCallListenerextendsPhoneStateListener{

        @OverridepublicvoidonCallStateChanged(int state, String incomingNumber) {
            // TODO Auto-generated method stubswitch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                    // your logic herebreak;

            default:
                break;
            }

            super.onCallStateChanged(state, incomingNumber);

        }
    }

Solution 2:

You need to declare PhoneStateListener in your Activity or Service:

PhoneStateListenerphoneStateListener=newPhoneStateListener() {
    @OverridepublicvoidonCallStateChanged(int state, String incomingNumber) {
        if (state == TelephonyManager.CALL_STATE_RINGING) {
            ....
        } elseif(state == TelephonyManager.CALL_STATE_IDLE) {
            ....
        } elseif(state == TelephonyManager.CALL_STATE_OFFHOOK) {
            ....
        }
        super.onCallStateChanged(state, incomingNumber);
    }
};

And add following permission to AndroidManifest.xml:

<uses-permissionandroid:name="android.permission.READ_PHONE_STATE" />

Hope this helps.
