Can not acess url that are present in the html files from Webview in Android

I am trying to access the url using the shouldOverrideUrlLoading method. For some reason when I try to access the url that are present in the html files, I get Web page not available error.Previously I could access the url because I stored my html file in the raw folder but I needed to move it to assets folder as the code looks cleaner this way. This is my code, could anyone let me know how I can resolve this.

webview.setWebChromeClient(new WebChromeClient());
webview.setWebViewClient(new WebViewClient());
webview.loadUrl("file:///android_asset/myfile/file.html");
webview.setVerticalScrollBarEnabled(false);
webview.setWebViewClient(new WebViewClient()
{
    public boolean shouldOverrideUrlLoading(WebView view, String url) {

        if (url.equalsIgnoreCase("some text")){
            setDialog("some fancy text");
        }

Try to get the Real Path of the file first and then try as your way like this:

String YourURI="/android_asset/myfile/file.html";
YourURI = new File(getRealPathFromURI(YourURI));

//Got the Real Path Of the File

private String getRealPathFromURI(Uri contentURI) {
  Cursor cursor = getContentResolver().query(contentURI, null, null, null, null); 
  cursor.moveToFirst(); 
  int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
  return cursor.getString(idx); 
}

webview.setWebChromeClient(new WebChromeClient());
webview.setWebViewClient(new WebViewClient());
webview.loadUrl(YourURI);                      //**Used the Real Path**
webview.setVerticalScrollBarEnabled(false);
webview.setWebViewClient(new WebViewClient()
{
    public boolean shouldOverrideUrlLoading(WebView view, String url) {

        if (url.equalsIgnoreCase("some text")){
            setDialog("some fancy text");
        }
}

If the File is in the SDCARD :-

webview.setWebChromeClient(new WebChromeClient());
webview.setWebViewClient(new WebViewClient());
if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
{
  Log.d(TAG, "No SDCARD");
} 
else 
{
  webview.loadUrl("file://"+Environment.getExternalStorageDirectory()
                                   +"/android_asset/myfile/file.html");
}
webview.setVerticalScrollBarEnabled(false);
webview.setWebViewClient(new WebViewClient()
{
    public boolean shouldOverrideUrlLoading(WebView view, String url) {

        if (url.equalsIgnoreCase("some text")){
            setDialog("some fancy text");
        }
}

Final Edit:- This Code Works Perfectly for Asset Folder

public class MyActivity extends Activity {  
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);  
        WebView webview;  
        webview = (WebView) findViewById(R.id.webView1);  
        webview.loadUrl("file:///android_asset/myfile/file.html");
    }  
}

shouldOverrideUrlLoading does not work on ICS for file://, but works for fine for external urls. loadURL works fine loading from the assets folder.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    WebView web=(WebView)findViewById(R.id.webView1);

    web.setWebViewClient(new MyWebClient());
    //web.loadUrl("file:///android_asset/index.html");
    web.loadUrl("http://google.com");

.....

class MyWebClient extends WebViewClient
{
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        Log.d("MyWebClient", "url is: " + url);

        if (url.equalsIgnoreCase("google.com")){
            Log.d("MyWebClient","url is: " + url);
        }
        return false;
    }

}

You may try for this too -

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        String myURL = "file:///android_asset/index.html";
        myBrowser=(WebView)findViewById(R.id.mybrowser);

        /*By default Javascript is turned off,
         * it can be enabled by this line.
         */
        myBrowser.getSettings().setJavaScriptEnabled(true);
        myBrowser.setWebViewClient(new WebViewClient());

        myBrowser.loadUrl(myURL);

    }

and also check you have placed the file in correct folder of main project. If all this is ok, make a clean project and fix project. Then try to run it.

This would work well try it-----

"android.resource://[package]/[res type]/[res name]"

Uri path = Uri.parse("android.resource://com.androidbook.samplevideo/raw/myvideo");

There is another way that would also work for you---

webView.loadData(customHtml, "text/html", "UTF-8");

where custromHtml is the HTML line that is used to be displayed.

on the place of "custromHtml" you just pass "file://android_asset/myfile/file.html".

I think this should work.

I think you should try this ....

webview.setWebChromeClient(new WebChromeClient());
webview.setWebViewClient(new WebViewClient());
webview.loadUrl("file://android_asset/myfile/file.html");
webview.setVerticalScrollBarEnabled(false);
webview.setWebViewClient(new WebViewClient()
{
    public boolean shouldOverrideUrlLoading(WebView view, String url) {

        if (url.equalsIgnoreCase("some text")){
            setDialog("some fancy text");
        }
