Convert a website to an android application [close

问题:

I built a site in asp.net C#. Visual Studio 2010.

The site scales nicely and fits on my phone and other Android divices. It database driven also. I want to make an app for the android market out of my site now. Free app.

Can i easily accomplish this? Can a app be as simple as launching a browser window? Will the android market accept an app like that?

Point me in the right direction please. Im unsure where to start.

What you describe can be easily accomplished using a WebView.

WebView (from android developers) : A View that displays web pages. This class is the basis upon which you can roll your own web browser or simply display some online content within your Activity. It uses the WebKit rendering engine to display web pages and includes methods to navigate forward and backward through a history, zoom in and out, perform text searches and more.

Here's a simple sample app:

public class WebActivity extends Activity {

    WebView mWebView;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        final Activity mActivity = this;
        super.onCreate(savedInstanceState);

        // Adds Progrss bar Support
        this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
        setContentView(R.layout.main);


        // Makes Progress bar Visible
        getWindow().setFeatureInt( Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);

        mWebView = (WebView) findViewById( R.id.webview );
        mWebView.getSettings().setJavaScriptEnabled(true);     
        mWebView.loadUrl(http://your.url.com);


        mWebView.setWebChromeClient(new WebChromeClient() 
        {
            public void onProgressChanged(WebView view, int progress)  
            {
                //Make the bar disappear after URL is loaded, and changes string to Loading...
                mActivity .setTitle("Loading...");
                mActivity .setProgress(progress * 100); //Make the bar disappear after URL is loaded

                // Return the app name after finish loading
                if(progress == 100)
                {
                    financialPortalActivity.setTitle(R.string.yourWebSiteName);
                }
            }
        });
    }
}

and a very simple layout file: main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">

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

Of course you will have to set a permission in your Manifest:

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