You should set "android:usesCleartextTraffic" flag to true in your AndroidManifest file.
Since target api 28 it defaults to false. more info here

Because of volley default retry policy your your request is processing two times, try this code to avoid it.
stringRequest.setRetryPolicy(new DefaultRetryPolicy(20 * 1000, 0, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
RequestQueue requestQueue = Volley.newRequestQueue(_context);
requestQueue.add(stringRequest);

You are fetching data from intent.getStringExtra("description") but you didn't add data into Intent which you want to pass, Try this,
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent intent=new Intent(getApplicationContext(),ArticleActivity.class);
intent.putExtra("description","whatever data you want to pass");
startActivity(intent);
}
});
And load your URL in below way,
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.loadUrl("http://www.example.com");
Load an URL in webview:
private String url="https://newsapi.org/v1/articles?source=techcrunch&apiKey=59b308aec9f242fe98b527ab9ba93199";
WebView webView=(WebView)findViewById(R.id.webView);
webView.loadurl(url);
https://developer.android.com/reference/android/webkit/WebView.html#loadUrl(java.lang.String)
How do I get the json result from onPostExecute to another activity? I was able to get the user details from the database based on the username logged in. So in my HomePageActivity there is a button to go to profile and when I clicked on btnprofile it displays the user details on textviews in the current activity(HomePageActivity) but what I wanted to do is to get the user details and then display it to a new activity, which is in the Profile Activity. I tried using Intent but when I go to Profile Activity it displays nothing. Can you please help me? :(

It is because new activity starts before async task is completed. Just call function for start new activity in onPostExecute() function.
Pass values after fetching the details. Is the settext working properly? then you can give the intent at that scope, in the onPostexecute method. Look before doing this.Look this
First I will describe the process/problem briefly in words. Afterwards, I'll attach all of the code.
I start the android application in debug mode.
Main activity gets called.
It calls Activity2 via "intent".
Then (in onCreate) I start an Async activity in order to get information from a webserver. I do that with this command "new Kontakt(info1, info2, information).execute();"
I've put a break point at the onPostExecute method in "Kontakt" to see what happens. But!! It doesn't stop there. So then I figured, "okey, the doInBackground method didn't get called for some reason"
When I continue to run the code, as a surprise, onPostExecute gets called (somewhere at the end of onClick) and stops at the break point just the way I want it but than it's too late, because I'd like to have the output already in the onCreate method where I called "new Kontakt(info1, info2, information).execute();".
So why does it call onPostExecute too late and what can I do to make the process call it properly already in onCreate at the line "new Kontakt(info1, info2, information).execute();" in Activity2?

In Activity2, when onCreate() calls new Kontakt(info1, info2, information).execute();:
an asynchronous task (Kontakt) is started in the background
the execution of onCreate() continues
so it's normal that you don't have the response immediately.
