'Webpage not available' with WebView.loadData() ONLY in emulator

Question

I'm calling loadData on my WebView and passing it some HTML in the form of a String like so:

webView.loadData( htmlString, "text/html", "utf-8" );

It works fine on my Galaxy Tab 10.1, but the WebView displays:

Webpage not available

when running on the emulator with everything set up to match my Galaxy Tab. Setting android.permission.INTERNET in the manifest has no effect, though I shouldn't need that permission since I'm rendering in-memory HTML, and not accessing anything over the data connection.

What's going on?

Answer 1

Try with this code

webView.loadData( URLEncoder.encode(htmlString).replaceAll("\\+"," "), "text/html", "utf-8" );

insted of

webView.loadData( htmlString, "text/html", "utf-8" );

it should work, because sometimes character like '%', '\', '#' creates problem if its not properly Encoded

Answer 2

In 2.x platforms loadData() fails in some cases (it requires the html to be escaped), use loadDataWithBaseURL() instead and pass null for baseUrl and historyUrl:

webView.loadDataWithBaseURL(null, htmlString, "text/html", "utf-8", null);
