MainActivity.java
package com.blogspot.android_er.androidinternet;

import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;
import android.widget.Toast;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

public class MainActivity extends AppCompatActivity {

TextView textResult;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textResult = (TextView)findViewById(R.id.tresult);

MyThread myThread = new MyThread("http://android-er.blogspot.com", textResult);
myThread.start();
}

class MyThread extends Thread{
String target;
TextView textviewResult;

private Handler handler = new Handler();

public MyThread(String target, TextView textviewResult) {
super();
this.target = target;
this.textviewResult = textviewResult;
}

@Override
public void run() {
String result = "";

try {
URL url = new URL(target);
URLConnection urlConnection = url.openConnection();
InputStream inputStream = urlConnection.getInputStream();
InputStreamReader inputStreamReader =
new InputStreamReader(inputStream);
BufferedReader buffReader = new BufferedReader(inputStreamReader);

String line;
while ((line = buffReader.readLine()) != null) {
result += line;
}

} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

final String finalResult = result;
handler.post(new Runnable() {
@Override
public void run() {
textviewResult.setText(finalResult);
Toast.makeText(MainActivity.this,
"finished", Toast.LENGTH_LONG).show();
}
});
}
}
}
