I have downloaded map750.png file in the root of sdcard, but when I try to show it within a webview with some text, only the text is shown. Could you help me to 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 edit the post to add the solution suggested by oneilse14, thanks!!

mWebView.loadDataWithBaseURL("", html, "text/html", "utf-8", "");
Try this,
Check out loadDataWithBaseURL() in the Developer docs
http://developer.android.com/reference/android/webkit/WebView.html
loadData() has certain restrictions on what it can display. This method is able to display local device files like you are trying to do.
Note that the access using the file:// schema can fail due security restrictions.
Another approach is to use the URI of a ContentProvider that handles the local file access. Overwrite openFile(Uri, String) in a subclass of ContentProvider for this approach.
