Когда я открываю приложение, его грохот перед тостом показывает. Я не знаю, как я должен использовать мой метод isOnline()ошибка приложения при отсутствии подключения к Интернету до открытия приложения
public class Url_cont extends AsyncTask<String, Object, ArrayList<Movie>> {
final String log_tag = Url_cont.class.getSimpleName();
ArrayList<Movie> resultObj = new ArrayList<>();
ICallBack myCallBack;

this.mContext = mContext;
}

return netinfo != null && netinfo.isConnectedOrConnecting();
}
@Override

progressDialog.show();
} else {
Context context = mContext;
CharSequence text = "check your internet connection!";
int duration = Toast.LENGTH_LONG;

toast.show();
}
}
private ArrayList<Movie> formatMyJson(String jsonstr) throws JSONException {

И эта ошибка показывает

поделиться файлом манифеста, и каков ваш целевой SDK? –
Возможно, ваше приложение исключено из приложений, которые по умолчанию могут пользоваться Интернетом. Например, некоторые устройства Huawei делают это .... – Opiatefuchs
или, если вы внесли изменения и забыли сделать чистый проект? Удалите приложение с устройства, очистите проект и переустановите его. – Opiatefuchs
