How to display some HTML text in a web viewer ?


For the example, I uploaded a html page as asset into App Inventor.
There is one of special thing to consider for HTML documents uploaded as assets into App Inventor: During development, you have to use the development path to the embedded HTML document.
"file:///mnt/sdcard/AppInventor/assets/webviewstring.html"

Before building the app, use the production path.
"file:///android_asset/webviewstring.html"

" <!DOCTYPE html>
<html>
<head>
 <meta name="author" content="puravidaapps.com">
 <meta charset="utf-8">
 <meta name="viewport" content="width=device-width, initial-scale=1">
 <title>Label</title>
 <script src="jquery-1.8.0.min.js"></script>
 <script>
 // urldecode function, which also handles the case of spaces being encoded as +
 // http://stackoverflow.com/a/4458580/1545993
 function urldecode(str) {
 return decodeURIComponent((str+'').replace(/\+/g, '%20'));
 }
 </script>
</head>

<body>
 <script>
 // get the text to display from the webviewstring, urldecoded
 var strLabel = urldecode(window.AppInventor.getWebViewString());


 // append the text to the body of the html document
 $("<div>" + strLabel + "</div>").appendTo("body");
 </script>
</body>
</html> "

Note: To use this example, you have to upload the library jquery-1.8.0.min.js into the assets of your project.

How to Reduce Lazy Load Resources in Website Reduce Lazy Load Resources: Utilize lazy loading for resources such as images, scripts, and stylesheets.
