• Situation : So I debugged and found that the first api call im doing in which using

  HttpClient httpclient = new DefaultHttpClient();

  the next step its going to AsyncTask public AsyncTask(@Nullable Looper callbackLooper) { 's catch block and displaying above error

  but when i tried on other device with android sdk version less than 28 ie 27 its working fine with no errors

  In advance Thanks for helping
