Why doesn't this class return the JSON data from given URL?

The class that I have made does not fetch data from the given URL which I have as a String. In a static initializer I make a URL from the String, and then getResponseFromHttpUrl method should have returned the JSON data as a String. However my Log.d("jsondata") don't show anything at all and my app crashes.
package com.example.android.bakingapp;
import android.util.Log;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Scanner;
public class RecipeJson {
public static final String url = "https://d17h27t6h515a5.cloudfront.net/topher/2017/May/59121517_baking/baking.json";
public static URL urlBuilt;
public static String jsonData;
static {
try {
urlBuilt = buildUrl();
jsonData = getResponseFromHttpUrl(urlBuilt);
Log.d("jsondata", jsonData);
} catch (Exception e) {
e.printStackTrace();
}
}
public static URL buildUrl() throws java.net.MalformedURLException {
return new URL(url);
}
public static String getResponseFromHttpUrl(URL url) throws IOException {
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
try {
InputStream in = urlConnection.getInputStream();
Scanner scanner = new Scanner(in);
scanner.useDelimiter("\\A");
boolean hasInput = scanner.hasNext();
if (hasInput) {
return scanner.next();
} else {
return null;
}
} finally {
urlConnection.disconnect();
}
}
}
Here are the app logs:

What I've missing or what I'm doing wrong?

You haven't defined any view for your fragment, so it is unable to find that relevant id thus resulting in Null Pointer Exception. Override onCreateView() method in your fragment and provide a view in that and then write your findViewById code in this method like this
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.layout, container, false);
btn_name= (Button) view.findViewById(R.id.your_button_id);
return view;
}

You can't instantiate view using getActivity() in Fragment.
You have to do like below and remove instantiation from onResume():
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.your_fragment_layout, container, false);
scanBtn = (Button) view.findViewById(R.id.scan_button);
formatTxt = (TextView) view.findViewById(R.id.scan_format);
contentTxt = (TextView) view.findViewById(R.id.scan_content);
scanBtn.setOnClickListener(this);
return view;
}

Grid-view is not formed in horizontal-scrolling-pages like home screen when app is in Background or Process is died

I am developing Horizontal Scrolling pages and tabs
MY app is working well in all devices in foreground, but when it goes to background, after one hour, the logs saying that Process com.example.myapp has died. When i reopen the app , the gridview data is not appearing but when scrolling horizontally , getView() method displaying all data like images and text.
that means app has data but view is not formed when process has died. And if i press back button and re-open the app, It is working good

Actually, some data is being saved with onSavedInstaceState(). The data is not being deleted when process has been killed on LowMemory.
I fixed this with
#Override
protected void onSaveInstanceState(Bundle outState) {
//super.onSaveInstanceState(outState);
}
Just do not call super class. Just comment like above

Error await must not be called on the UI Thread in Android project

I am currently trying to read data from google drive, using a query then transferring the gson to a fragment so I can set the edit text values of said fragment to the gson being read in (Kudos if you followed that!)
Every time I move to open the fragment I am getting the following error message:

As stated in the Exception message, you shouldn't use await on the UI thread.
Setting a new thread to handle the data should fix it.
[EDIT 1]
The "onResult" function is called on the UI Thread as mentioned in https://developers.google.com/android/reference/com/google/android/gms/common/api/ResultCallback#public-method-summary
public abstract void onResult (R result)
Called when the Result is ready.
It is the responsibility of the callback to release any resources
associated with the result. Some result types may implement
Releasable, in which case release() should be used to free the
associated resources.
This method is called on the main thread, unless overridden by
setHandler(Handler).
