Hi Andreas,
Congratulations! I think an APK is just a .ZIP file with another extension, so you can probably rename it to a .ZIP file, unzip the contents, add the xxhdpi icon and add it’s name to some list (do a search for another icon name to find the right place) and then re-ZIP the hole package and rename to .APK again.
Completely untested, but seems feasible in my mind 
Hi Andreas,
Does it not work if you simply include the an Icon-xxhdpi.png file in your project directory?
No, Joshua Quick already posted about this:
Corona Simulator builds do not currently support xxhdpi icons. Corona only supports the icons documented here…
http://docs.coronalabs.com/daily/guide/distribution/buildSettings/index.html#android
I think this won’t work, you’ll have to do all the codesingning stuff. Had to do this a long time ago when I used Adobe AIR and packaged the runtime into the APK, it was quite an effort.
So the best solution would be for Corona Labs to support the xxhdpi icons, because at some point in time they have to support it, so now would be best because it is a blocker. Please? 
Best,
Andreas
Andreas,
xxhdpi icon support will be available in daily build #1204. That build has had all of its sample projects updated to use our new “Icon-xxhdpi.png” icon file, which is 144x144 pixels. This is the same size as an iPad retina app icon. We’ve tested our xxhdpi icon support on a New Nexus 7 and Sony Xperia Z… and it works great! Sorry to keep you (and others) waiting for this feature. (So much to do, so little time.)
Hi Joshua,
this was fast - thanks a lot! And keep it up - it’s great that you’re always implementing new stuff and still are prepared to act fast if something comes up!
Best,
Andreas
Happy to help! We definitely try our best!
It looks like our daily build system ran into some problems and didn’t publish the daily build. Sorry about that. I was hoping to make this change available to you last weekend. We’re having our IT guy look into this issue now.
Andreas, the daily build supporting xxhdpi app icons is available now.
Hi Joshua,
thanks a lot, just downloaded the new daily build.
And no problem with the weekend, Google sent me a big list with things to change/optimize, they even demand that I change my “Freeze!” icon because they don’t like the rounded corners (I used the same icon for iOS and Android, and now they want me to change the icon and use rounded corners with a maximum radius of 10% of the icon radius).
But whatever, Android 4.3 looks great and if they promote my game for free it’s the least I can do.
Best,
Andreas
Well, I guess this justifies my reason for making a separate 144x144 pixel “Icon-xxhdpi.png”, because the iPad “Icon-72@2.png” is 144x144 pixels too. I was briefly thinking maybe I should support using the iPad retina app icon as an xxhdpi icon, but thought maybe developers would like the option to make a separate set of Android icons. Or perhaps icons that more closely resemble the themes on iOS and Android.
Yes, definitely a good call. I think they started this app icon micromanagement with the release of Android 4.3, and who knows what they will come up with next, like every icon needs a red bandana or the icon can only be half size for free apps.
