처음으로 브로드캐스트 리시버를 공부 하고있는대, 자꾸 sendReciver에서 오류가 납니다. 블로그를 보고 따라 하고 있는 거지만 왜 이런 오류가 나는지 궁금해가지고 질문 드립니다.
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent =new Intent();
intent.setAction("android.intent.action.HEADSET_PLUG");
sendBroadcast(intent);
}
}
