    The update of the Launcher 2.1 was pushed out to me phone. It is totally broken. Demo’s don’t work, my zip’s don’t work. Everything just shows the spinning spiral of death until I kill the app.

    How do I downgrade – this puts me dead in the water.

        This happens to me too, i need to change the .zip file’s name from “Game Name (1).zip” to “” and it fixes the problem.

    The message “Cordova support is now always available for all platforms and environments in CocoonJS” is very cryptic… Does this mean I can upload a cordova project when compiling with canvas+? or does this mean I can use cocoonjs API using cordova application?

    Hello, everyone, I’m trying to build my games in hours Ludei, but it gives the following error:

    “Something went wrong during the compilation of your project
    Plugin(s) found in your project
    – org.apache.cordova.inappbrowser
    The command ‘build’ failed.”

    I exported using the option Cordova, send the .zip file to the Ludei site.

    In project information: marked the Cordova option, and filled out the standard fields.

    In compile project: marked Android.
    Run using = System WebView
    Compiler version = 3.5 and 3.6

    No works, does anyone know what’s wrong?
