Android Json Parser From Url (non Depecreated)

Okay I'm coming close to my wits end here. I have been following code samples and reading threads on how to hit a URL and read in the JSON object following that web request. But th

Solution 1:

From this sample project from this book, here is a thread that loads the latest Stack Overflow android questions using HttpURLConnection and parses them using Gson:

      try {
        InputStream in=c.getInputStream();
        BufferedReader reader=
            newBufferedReader(newInputStreamReader(in));
        SOQuestions questions=
            newGson().fromJson(reader, SOQuestions.class);

        reader.close();

        EventBus.getDefault().post(newQuestionsLoadedEvent(questions));
      }
      catch (IOException e) {
        Log.e(getClass().getSimpleName(), "Exception parsing JSON", e);
      }
      finally {
        c.disconnect();
      }
    }
    catch (Exception e) {
      Log.e(getClass().getSimpleName(), "Exception parsing JSON", e);
    }
  }
}

Here, SOQuestions is the Gson-annotated class for the Stack Exchange questions API, and I am using greenrobot's EventBus to get the results over to a fragment. Of course, you would replace the Stack Exchange API URL with your own and would need to parse whatever its JSON output is.

I'm not aware of many Android developers using JSONObject anymore, given much better options in Gson, Jackson, etc., but you would need to read in the InputStream into a String to pass to the appropriate JSONObject constructor.

You might also consider using higher-order approaches. For example, this sample app is a clone of the first that uses Square's Retrofit library for contacting the Stack Exchange API Web service, rather than HttpUrlConnection.
