The easiest way to do this is with a webview. The only problem with a webview is that its a pain to change the font. Well not anymore

?View Code JAVA
String head = "<head><style>@font-face {font-family: 'myface';src: url('fonts/Roboto-Light.ttf');}body {font-family: 'myface';} img { max-width: " + width + "px; }</style></head>";
String htmlData = "<html>" + head + "<body>" + strHTML + "</body></html>";
WebView wv = ((WebView) findViewById(R.id.wvReview));
wv.loadDataWithBaseURL("file:///android_asset/", htmlData, "text/html", "UTF-8", null);

The above snippet also makes sure all your images fit on your display

This code will prevent that

?View Code JAVA
pw = new PopupWindow(layoutInflater.inflate(R.layout.firstrundisclaimer, null, false), dipToPx(280), dipToPx(390), true);
findViewById(R.id.content).postDelayed(new Runnable() {
	public void run() {
		try {
			pw.showAtLocation(findViewById(R.id.content), Gravity.CENTER, 0, 0);
		} catch (Exception e) {
		}
	}
}, 500);

However, I’ve noticed that ISPS tend to cache these files so the software app isnt always getting the latest file.

step 1 – create a php function to download a file

?View Code PHP
<?php
 
$filename = $_GET['filename'];
$path = $_SERVER['DOCUMENT_ROOT'] . "/$filename";
if ($fd = fopen($path, "r")) 
{
    $fsize = filesize($path);
    header("Cache-Control: no-cache, must-revalidate"); 
    header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); 
    header("Content-type: application/octet-stream");
    header("Content-Disposition: filename=\"" . $filename . "\"");
    header("Content-length: $fsize");
    header("Cache-control: private"); //use this to open files directly
    while (!feof($fd)) 
    {
        $buffer = fread($fd, 2048);
        echo $buffer;
    }
}
fclose($fd);
?>

step 2 – rewrite urls so that when requesting /some_file.rar, it redirects to the php app as defined

?View Code HTML
Options +FollowSymlinks
RewriteEngine on
RewriteRule ^(.+)\.rar$ ./getfile.php?filename=$1.rar [NC]
