    {
        super.onCreate();
        try
        {
            StateListener phoneStateListener = new StateListener();
            TelephonyManager telephonymanager = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
            telephonymanager.listen(phoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);

                    try{
                        TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
                        Class c = Class.forName(manager.getClass().getName());
                        Method m = c.getDeclaredMethod("getITelephony");
                        m.setAccessible(true);
                        ITelephony telephony = (ITelephony)m.invoke(manager);
                        telephony.endCall();
                    }catch(Exception e){
                        Log.d("",e.getMessage());
             }

                    break;
                case TelephonyManager.CALL_STATE_OFFHOOK:
                    break;
                case TelephonyManager.CALL_STATE_IDLE:
                    break;
            }
        }
    };
    public void onDestroy()
    {

    }

}

    void answerRingingCall();

    void silenceRinger();

You can generate your own activity that handles action "ACTION_ANSWER".

Here is a blog post which suggest a possible workaround.

Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);             
  buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
  getContext().sendOrderedBroadcast(buttonUp, "android.permission.CALL_PRIVILEGED");
