// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
//     ie === undefined
// If you're in IE (>=5) then you can determine which version:
//     ie === 7; // IE7
// Thus, to detect IE:
//     if (ie) {}

   typeof +'12s';   // number

At seajs/src/util-path.js, double slash has not been replaced!

  var DOT_RE = /\/\.\//g

    path = path.replace(DOT_RE, '/')

If you use add file add some files in your project. You can access them like this:

    NSError *error;
    NSString *filepath = [[NSBundle mainBundle] pathForResource:@"hello" ofType:@"txt"];  // I add __hello.txt__ into my project.
    NSString *filecontent = [NSString stringWithContentsOfFile:filepath encoding:NSUTF8StringEncoding error:&error];
    NSLog(@" content: %@", filecontent);

WebView Lifecycle

We ran into a problem when leaving the activity. WebView will display the following message in logcat:

EventHub.removeMessages(int what = 107) is not supported before WebViewCore is set up

To prevent this message from showing up use WebView stopLoading() method:

  // !!! This method is wrong!
  // !!! Do not solve problem
  @Override
 public void onStop() {

At Activity:

  //...
  webView.getSettings().setUserAgentString("CUSTOM_USE_AGENT");
  //...
