Create News App
As usual File=>create news app project and choose Empty Activity, after creating the project open the default class of MainActivity.java file and add the following below code,
MainActivity.java
package com.dude.newsapp;
import android.content.Intent;
import android.os.AsyncTask;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {
String API_KEY = "8190df9eb51445228e397e4185311a66"; // ### YOUE NEWS API HERE ###

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listNews = findViewById(R.id.listNews);
loader = findViewById(R.id.loader);
listNews.setEmptyView(loader);
if (Function.isNetworkAvailable(getApplicationContext())) {
DownloadNews newsTask = new DownloadNews();
newsTask.execute();
} else {
Toast.makeText(getApplicationContext(), "No Internet Connection", Toast.LENGTH_LONG).show();
}
}
class DownloadNews extends AsyncTask<String, Void, String> {

protected String doInBackground(String... args) {
String xml = Function.excuteGet("https://newsapi.org/v1/articles?source=" + NEWS_SOURCE + "&sortBy=top&apiKey=" + API_KEY);
return xml;
}
@Override
protected void onPostExecute(String xml) {
if (xml.length() > 10) { // Just checking if not empty
try {
JSONObject jsonResponse = new JSONObject(xml);
JSONArray jsonArray = jsonResponse.optJSONArray("articles");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
HashMap<String, String> map = new HashMap<>();
map.put(KEY_AUTHOR, jsonObject.optString(KEY_AUTHOR));
map.put(KEY_TITLE, jsonObject.optString(KEY_TITLE));

dataList.add(map);
}
} catch (JSONException e) {

ListNewsAdapter adapter = new ListNewsAdapter(MainActivity.this, dataList);
listNews.setAdapter(adapter);
listNews.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent i = new Intent(MainActivity.this, DetailsActivity.class);
i.putExtra("url", dataList.get(+position).get(KEY_URL));
startActivity(i);
