It does not seem to work with Canvas+.
It only works with Webview and Webview+.
Not even a simple project (a single sprite on the layout) worked. I tried using all the settings you've recommended and adding the "|| this.isCocoonJS" line on the right place..
Are you using the latest C2 version? And what do you have set the Cocoon version, the latest one?
Should I export the game as a CocoonJS project, a Cordova project or a HTML5 project (then zip it)?
edit: could you try out this apk? It's just a blue background and a purple sprite over it. In here, the screen keeps flashing non stop and the purple sprite only shows on the bottom left (in the code, the purpe square should be over most of the screen).
I'm using Canvas+ on my own and it's always working fine.
You find many free examples here
can you try one of them? I'm not quite sure why this is happening on your end but I assume it's just a setting issue.
You also find a guide for Construct 2 and CocoonIO here
I also made a capx template with the settings I use. You can download it for free here.

Just scroll down to the end of the post.
I'm sorry I only have an iPhone at the moment. So I can't test your apk file.
