How to get phone number from an incoming call?

Question

How do I get the phone number when there is an incoming call in Android?

Answer 1

This will definitely help you.

Here is an implementation, which will allow you to retrieve the phone number if it is an incoming phone call as incoming Number, and also when the call is FINISHED - note the Handler() code.

private class PhoneCallListener extends PhoneStateListener {

private boolean isPhoneCalling = false;

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

    if (TelephonyManager.CALL_STATE_RINGING == state) {
        // phone ringing
        Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
    }

    if (TelephonyManager.CALL_STATE_OFFHOOK == state) {
        // active
        Log.i(LOG_TAG, "OFFHOOK");

        isPhoneCalling = true;
    }

    if (TelephonyManager.CALL_STATE_IDLE == state) {
        // run when class initial and phone call ended, need detect flag
        // from CALL_STATE_OFFHOOK
        Log.i(LOG_TAG, "IDLE number");

        if (isPhoneCalling) {

            Handler handler = new Handler();

            //Put in delay because call log is not updated immediately when state changed
            // The dialler takes a little bit of time to write to it 500ms seems to be enough
            handler.postDelayed(new Runnable() {

                @Override
                public void run() {
                    // get start of cursor
                      Log.i("CallLogDetailsActivity", "Getting Log activity...");
                        String[] projection = new String[]{Calls.NUMBER};
                        Cursor cur = getContentResolver().query(Calls.CONTENT_URI, projection, null, null, Calls.DATE +" desc");
                        cur.moveToFirst();
                        String lastCallnumber = cur.getString(0);
                }
            },500);

            isPhoneCalling = false;
        }

    }
} 

And then add and initialise the listener in your onCreate or onStartCommand code:

  PhoneCallListener phoneListener = new PhoneCallListener();
TelephonyManager telephonyManager = (TelephonyManager) this
        .getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(phoneListener,
        PhoneStateListener.LISTEN_CALL_STATE);
