Upload text file to webview android

So far I have read how to load “regular” html web pages into a web view. so far I am passing the url containing the path to my text file, but it is not loading anything. this is my method:

@Override public void onSelected(String url) { ViewerFragment viewer = (ViewerFragment) getSupportFragmentManager() .findFragmentById(R.id.view_fragment); if (viewer == null || !viewer.isInLayout()) { Intent showContent = new Intent(getApplicationContext(), ViewerFragment.class); showContent.setData(Uri.parse(url)); startActivity(showContent); } else { viewer.updateUrl(url); } }

and the viewer fragment received the following:

  public class ViewerFragment extends Fragment{ private WebView viewer = null; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { viewer = (WebView) inflater .inflate(R.layout.details_fragment, container, false); return viewer; } public void updateUrl(String newUrl) { if (viewer != null) { viewer.loadUrl(newUrl); } } }

but keep getting this screen: webviewerror

any ideas how to do this? = / I already tried to work a little, but did not find much information about this ... in fact, almost did not find anything. Therefore any help would be appreciated.

Try reading the contents of the text file and the text prefix using <html><body> , then add </body></html> , then use the WebView method loadData(...) .

Example:

 StringBuilder sb = new StringBuilder("<html><body>"); sb.append(readTextFile()); sb.append("</body></html>"); myWebView.loadData(sb.ToString(), "text/html", "UTF-8"); public String readTextFile(String filename) { // Open and read the contents of <filename> into // a single string then return it }
