I create an android application that the program should connect to the internet and when i pressed Go button, the program should to open the webView page(google.com). My program can’t connect to the internet and i don’t know why? I add log.i() function to the program that when i clicked button, i see this.
Go.java
package org.example.test;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.webkit.WebView;
import android.widget.Button;
import android.view.View.OnClickListener;
public class MainActivity extends Activity{
private WebView webView;
private Button go_button;
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
Log.i(UI_MODE_SERVICE, "HELOOOOOOOOOOOOOOOOOO");
setContentView(R.layout.activity_main);
webView=(WebView) findViewById(R.id.web_view);
go_button=(Button) findViewById(R.id.go_button);
go_button.setOnClickListener(new OnClickListener(){
public void onClick(View view){
Log.i(UI_MODE_SERVICE, "STARRRRRRRRRRRRRRT");
webView.loadUrl("http://www.google.com");
Log.i(UI_MODE_SERVICE, "BYEEEEEEEEEEEEEEEEEEEEE");
}
});
}
}
MainActivity:
package org.example.test;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}

Thanks for advise.
Cheers.
1) Your stack traceback is illegible: I don’t see if there’s an error
2) Thank you for including your AndroidManifest.xml. I don’t see “internet” permissions – you need it!
