    Great release! The new Custom Launcher will help a lot!

    But I found a bug… When I use the app to test my project, it works fine, but when I compile and try to test, the sound stops in the beginning and then, the sound doesn’t work anymore

    I hope you understand… English is not my native language…

    Glad there is an update…..

    no Ouya yet? uggg sigh πŸ™ very sad. You have Tizen and other very new platforms. yet Ouya is running on a base android. It has 2 custom Api’s to support. Controller and In App Purchases. yet no support.

    very very sad.

    Great Stuff, but…

    I gave tried the code from the documentation

    And my Android launcher’s debug says:
    Cannot open the javascript file ‘js/CocoonJSExtensions/CocoonJS_App_ForCocoonJS.js’: The server responded with status 404 (NOT_FOUND)

    Cannot open the javascript file ‘js/CocoonJSExtensions/CocoonJS_App.js’: The server responded with status 404 (NOT_FOUND)

    and so on…

    and the same with jQuery.js, pixi,js or any js file.

    Hi! I’m a construct 2 user and I have a problem with sounds(music) – they are stops in the beginning…

  11. avatarDani

    This version does not work. Before I was perfect, but now is no more than the home screen. First off the sound and then to the full game. How I can install the previous version? Thank you.

    I have been getting random game crash/hang with the updated CJS launcher on Android.

    Tested extensively on PC browser (via Construct2) with no problem.

    When on mobile launcher after exporting via CJS from Construct2, my sound effects seem to have high pitch and delay when transitioning to another layout.

  13. avatarUrtzi Jaureguibeitia

    @Ivan @Hydar

    We’re having problems with the sound but We are working on it. Please send us more info to devsupport email address, thanks!


    No, itΒ΄s not possible. We are working hard to fix it ASAP.
    Thank you for your patience.

    How about the splash screen. When can we do away with that. I want to use cocoonjs but I won’t till I can use my own splash screen.
