为什么这个代码不适用于android 6 marshmallow Api 23？它不会抛出异常,但callStateListener中的代码不起作用.

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
PhoneStateListener callStateListener = new PhoneStateListener() {
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        //if(logAtive) Log.i(LOG_TAG,incomingNumber + " " + state);
        if(state==TelephonyManager.CALL_STATE_RINGING){
            Toast.makeText(getApplicationContext(),"Hey, receive your call. Phone is ringing.",
                    Toast.LENGTH_LONG).show();
        }
        if(state==TelephonyManager.CALL_STATE_OFFHOOK){
            Toast.makeText(getApplicationContext(),"You are in a call. ",
                    Toast.LENGTH_LONG).show();
        }
        if(state==TelephonyManager.CALL_STATE_IDLE){
            Toast.makeText(getApplicationContext(),"You are in idle state… ",
                    Toast.LENGTH_LONG).show();
        }
    }
};

telephonyManager.listen(callStateListener, PhoneStateListener.LISTEN_CALL_STATE);
