I am developing a Caller Screen App in which I have two buttons accept and reject the call. Button reject is working properly, but the accept button is not working in all android version
iTelephony= (ITelephony) context
                .getSystemService(Context.TELECOM_SERVICE);
        try {
            iTelephony.answerRingingCall();
        } catch (RemoteException e) {
            e.printStackTrace();
        }
