Hi Subash, First step is to generate an api-report so we can see what Flex and third-party features your app used. See instructions here: https://github.com/apache/royale-asjs/wiki/Generating-an-API-Report
The next step is to replace all of your MX and Spark namespaces URIs in your MXML files: Replace: xmlns:mx="library://ns.adobe.com/flex/mx" With: xmlns:mx="library://ns.apache.org/royale/mx" And Replace: xmlns:s="library://ns.adobe.com/flex/spark" With: xmlns:s="library://ns.apache.org/royale/spark" Then try using the Royale compilers in the js/bin folder to compile your app. You will get a bunch of errors if emulations don't exist and either need to be created or in cases of using low-level Flash APIs, you may need to replace that code with something else. Once the errors are all resolved, you can try running the app. Currently only parts of a few emulation components work. We are seeking volunteers to help make more of the components work.

Yes Andrew, a document on this would help me a lot as I'm very new for Royale. ----- Regards, Subash Kunjupillai -- Sent from: https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fapache-royale-users.20374.n8.nabble.com%2F&data=02%7C01%7Caharui%40adobe.com%7C99a50ea1c70947fd24d908d5eb9725ff%7Cfa7b1b5a7b34438794aed2c178decee1%7C0%7C1%7C636673956766979408&sdata=da7JI4uxoEiwHNSWph8MuH1MzPLsEZu6h8gv8xKDCQ8%3D&reserved=0
