Open Local Html File in Webview - Android

I have a saved a file in the root folder and am trying to open it in a webview.

This is my code for saving:

    OutputStream outstream = null;
    outstream = openFileOutput(fileName ,MODE_WORLD_READABLE);

    /// if file the available for writing
    if (outstream != null) {
        /// prepare the file for writing
        OutputStreamWriter outputreader = new OutputStreamWriter(outstream);
        BufferedWriter buffwriter = new BufferedWriter(outputreader);

        /// write the result into the file
        buffwriter.write(result);
    }

    /// close the file
    outstream.close();

} catch (java.io.FileNotFoundException e) {
    System.out.println("File not found in the writing...");
} catch (IOException e) {
    System.out.println("In the writing...");
}

This is my code for recalling the file:

                    fileView.getSettings().setJavaScriptEnabled(true);
            fileView.loadUrl("file:///" + name); <---

and inside the app it gives me a file not found error.

Any insight is helpful.

Please refer to the youtube video https://youtu.be/n2KbDqoCv_Q?t=173

I've tested its solution and it works.

You can read your asset file first and then display it on webview via asd like this

        BufferedReader read = null; 
StringBuilder data = new StringBuilder(); 
try {
            read = new BufferedReader(new InputStreamReader(getAssets().open("htmlFile.html"), "UTF-8")); 
            String webData;
            while ((mLine = read.readLine()) != null) {
               data.append(mline);
            } 
    } catch (IOException e) {
             log(",e.getmessage()) } finally {
            if (reader != null) {
                 try {
                     reader.close();
                 } catch (IOException e) {
                     log(",e.getmessage())
                 }
            } 
    }

and then load this data in webview

webview.loadData(data, "text/html", "UTF-8");

For files that will be bundled with the application you can add an "asset" folder to your project by right clicking your app in the project explorer then select

New=> Folder=> Assets Folder.

Add the HTML file to your asset folder then load it by:

fileView.loadUrl("file:///android_asset/"+name);

same URL can be used in your HTML to link to other HTML or CSS files.

Actually when you open a URL using file:///...
Then it means that you should save the file under assets directory (say test.html ). Now suppose you have to access test.html file, you need to write like this

loadURL("file:///android_asset/test.html');

WebView mWebView=(WebView)findViewById(R.id.mWebView);

            mWebView.loadUrl("file:///book.html");
            mWebView.getSettings().setJavaScriptEnabled(true);
            mWebView.getSettings().setSaveFormData(true);
            mWebView.getSettings().setBuiltInZoomControls(true);
            mWebView.setWebViewClient(new MyWebViewClient());

private class MyWebViewClient extends WebViewClient 
{ 
    @Override 
    //show the web page in webview but not in web browser
    public boolean shouldOverrideUrlLoading(WebView view, String url) { 
        view.loadUrl (url); 
        return true;
    }
}

try this

The path is wrong, assuming the exceptions weren't hit.

file:/// tells the browser to look for /name

openFileOutput(fileName) tells the app to write in <application-files-directory>/fileName

Your url should be "file:///"+getFilesDir()+File.separator+fileName
