Please suggest any alternatives also.
You might want to look into StageWebView. Note that this won't be possible on iOS.
Thanks. I using StageWebView to display a local HTML file(file://). But while I tried adding ExternalInterface addCallBack code and tested in the emulator - got the following error
|Main Thread (Suspended: Error: Error #2067: The ExternalInterface is not available in this container. ExternalInterface requires Internet Explorer ActiveX, Firefox, Mozilla 1.7.5 and greater, or other browsers that support NPRuntime.)|
Does it mean ExternalInterface cannot be used in a Mobile project using StageWebView?
Do you get this same RTE if you run on device?
