Display image from SD card with idle web browsing

I uploaded the map750.png file to the sdcard root directory, but when I try to show it in a webview with some text, only the text is displayed. Could you help me find what is wrong in the code? thanks.

setContentView(R.layout.webview); mWebView = (WebView) findViewById(R.id.webview); mWebView.getSettings().setAllowFileAccess(true); mWebView.getSettings().setJavaScriptEnabled(true); mWebView.getSettings().setBuiltInZoomControls(true); String html = "<html><head></head><body><p>hello</p><img src=\"file://mnt/sdcard/map750.png\" alt=\"alternativo\" /></body></html>"; mWebView.loadData(html, "text/html","utf-8");

I am editing a post to add the solution suggested by oneilse14, thanks !!

See loadDataWithBaseURL () in the Developer Docs

http://developer.android.com/reference/android/webkit/WebView.html

loadData () has certain limitations on what it can display. This method is able to display the files of local devices that you are trying to make.

Try it,

  final String fileName = "file:///mnt/sdcard/1.jpg"; final String mimeType = "text/html"; final String encoding = "utf-8"; final String html = "<img src=\""+fileName+"\">"; webView.loadDataWithBaseURL("", html, mimeType, encoding, "");

Please note that access using the file: // scheme may cause a crash due to security restrictions.

Another approach is to use the ContentProvider URI, which handles access to the local file. Rewrite openFile (Uri, String) in a subclass of ContentProvider for this approach.
