코드는 다음과 같이 작성을 하였습니다.

protected void onCreate(Bundle savedInstanceState)
{
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);

    mTask = new TimerTask() {   //(UnityPlayerActivity.java:38)
        @Override
        public void run() {
            Intent intent = getIntent();   // 인텐트로 받아오기
            String name =  intent.getStringExtra("test");
            String name1 =  intent.getStringExtra("test1");
            Log.i("test", name);
            if(name1 != null)
                Log.i("test1",name1);
            }

            ArrayList<String> ar = getIntent().getExtras().getStringArrayList("List"); (UnityPlayerActivity.java:49)
    };
    mTimer = new Timer();
    mTimer.schedule(mTask,0,2000);


    mUnityPlayer = new UnityPlayer(this);
    setContentView(mUnityPlayer);
    mUnityPlayer.requestFocus();
}

 

 

Answer 1

ArrayList<String> ar = getIntent().getExtras().getStringArrayList("List");

구문에서 getIntent().getExtras()의 리턴값이 null로 보이네요.

그리고 해당 구문은 run() 메서드 안에 들어가야 할거 같은데

괄호 처리가 의도한대로 된걸까요? ^^

run() 메서드는 검색을 통해서 한거라서 뭘 넣어 줘야할지 모르겠습니다.
