Also, Construct 2 doesn't export native Android apk. It just let you export in a special format that make you be able to use third party services like Appmobi or CocoonJS...That is just embeded Html 5. Performances are nos the same.
CocoonJS is working with games exported by GD excepted that sadly texts are not rendered properly (it seems they does not support the way Pixi.js, the underlying JS library used by GD for rendering, handles texts), at least the last time have tested.
Intel XDK is pretty easy to use and an option should be added to the next version allowing to export a game packaged for it. For now, you can already use it! Just be sure to activate fullscreen at the launching of the game using the appropriate action. Export the game, then create a new Intel XDK project and finally put all files exported by GD in the Intel XDK folder.
You can then test it using their emulator and/or build an APK for Android (choose Crosswalk for better performance) or a iOS app.
