I am having difficulty in loading a html file from my project assets folder into a webview. I have looked at dozens of tutorials and solutions but none seem to work for me.

In my project's assets folder I have two simple html files. index.html and faq.html (The plan is to utilise this structure for my help documentation)

My code:

    WebView wv = (WebView)findViewById(R.id.webview1);
    wv.setWebViewClient(new WebViewClient() {  
          @Override  
          public boolean shouldOverrideUrlLoading(WebView view, String url)  
          {  
            view.loadUrl(url);
            return true;
          }  
        });         
    wv.loadUrl("file:///android_asset/index.html");

The webview displays the following:

Web Page Not Available

The Web Page at file:///android_asset/index.html could not be loaded as:

The requested file was not found. index.html

From everything I have read what I have here should work, but it does not.

your usage is right, so if has this problem, you need check the index.html file existed or not carefully, also you can clean the project, and rebuild it.

  • I have done a project clean with no result. How can I test if index.html existed? Is there a way to check the contents of the apk that ha sbeen installed on the emulator? – Daniel Neilsen Jan 05 '12 at 04:27

    the project path has a bin folder, the apk will save to here, you can use the zip tool to extra the file, you can check the asset folder. – idiottiger Jan 05 '12 at 04:31
  • Try accessing some other web page...if that loads then problem lies with index.html....there does not seem any error/problem with the code you have posted. – Usama Sarwar Jan 05 '12 at 04:41
  • I have opened the apk and neither assets/index.html or assets/faq.html are in the apk. Do I have to manually include the assets folder to be included? I thought eclipse did this automatically when setting up the project. – Daniel Neilsen Jan 05 '12 at 04:47

    I think I have found the cause of the problem. My project comprises of the project and then a separate library project. I was placing the files in the /assets folder of the library project which was not working but when placed in the /assets folder of the main project it works fine. I just need to figure out how to include the /assets folder of the library project in the apk. Thanks for the Help :) – Daniel Neilsen Jan 05 '12 at 05:19

You can try this code ....

WebView myBrowser;

    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);

    }
