context로 다른액티비티 메소드 호출하나 하려는데 계속 에러가 뜨는데요
Caused by: java.lang.reflect.InvocationTargetException
이 에러는 어떤경우에 뜨는거예요 ???
그리고 널포인트 저부분은
호출하는부분인데 호출받을때 널포인트가 나오면 어떤경우에 에러가 뜨나요 ??
받는곳
((MainActivity)MainActivity.mContext).gameEnd(); ---> 여기서 널포인트 뜬다고 나옴
보내는곳
public static MainActivity mContext;
호출한 메소드
public void gameEnd() {
// TODO Auto-generated method stub
if (20 > 10) {
Games.Achievements.unlock(mGoogleApiClient, getString(R.string.achievement_1));
}
문제가 뭘까요 ??
