Application is not working on launching from apps

Question

i have developed a simple android application, to show a web like Google. It is working fine, when launch from eclipse, does not work when relaunch from installed apps of emulator. Here is my WebView activity code

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        WebView mWebView = (WebView) findViewById(R.id.webView);
        mWebView.loadUrl("http://www.google.com");

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

Here is my .xml file

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <WebView
        android:id="@+id/webView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

</RelativeLayout>

try this

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


}


@Override
protected void onStart() 
{
    super.onStart();
         WebView mWebView = (WebView) findViewById(R.id.webView);
         mWebView.loadUrl("http://www.google.com");
    }
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

You have to add this line:

<uses-permission android:name="android.permission.INTERNET" /> 

outside the application tag in your AndroidManifest.xml
