ユーザーが選択した特定の時刻に通知しようとしています。この通知は、別のクラスにあるAsyncTaskを呼び出します。Android：通知でAsyncTaskを呼び出す例外
new ExtendedActivity().new Parse().getHoroscope("daily", signo);
私はgetHoroscopeにLog.dを入れているが、私は得る例外は、その前にある：私は例外私はこのコードでAsyncTaskことを呼び出すたびに取得しています。
例外：

クラス拡張
public class ExtendedActivity extends BaseActivity {
//AsyncThread
public class Parse extends AsyncTask<String, Void, String> {
public String getHoroscope(String type, String option){
String description="", site;
Log.d("Extended","inside getHoroscopes");
(...)
}
