I have everything set up correctly I think, When I run the layout in C2 clay.io logs in and post high score everything works correctly, but once I publish it on google play play store it dont work. I have sandbox disabled. I'm using CocconJS.

Once you create your game on Google Play Store using CocoonJS, you can't upload a .apk file from cross walk? I keep getting a error.

Upload failed
You uploaded an APK that is signed with a different certificate to your previous APKs. You must use the same certificate. Your existing APKs are signed with the certificate(s) with fingerprint(s):
[ SHA1: DE:C5:65:47:3C:31:22:AD:1D:38:FE:E2:B4:AC:E8:AD:9D:8E:F2:60 ]
and the certificate(s) used to sign the APK you uploaded have fingerprint(s):

Don't get Nokia Lumia 520 the first time the screen cracks your phone is useless have to have the touch screen replaced. Nokia Lumia 520 put the touch screen on the outside of the phone so its the first piece to break so stupid really, cause one small crack and its toast. Went through 2 Nokia Lumia 520 in a month cause there real cheap, but not worth it unless your just testing your games on it just don't drop it.

Every time I try to use the CoCoonJS Launcher on my phone I get a black screen, so I quit using it

I too have been wanting and needing this option to be available on C2, I have had 200+ downloads on my game on Google play store, but over half have deleted it cause they can't post there score or get there achievements. I will not use clay.io cause its wants every person to sign up for there services which made no one happy so I have disbanded that Idea, I can't ask everyone to sign up for a service they have never heard of. I really need Google Game Services there's just no doubt about it.

gfigueroa did you get it to work, I have not figured it out yet.

Well I dunno I just kinda added everyones idea and I just opened and closed my ap like 30 times and it worked everytime

Ok, the Refresh every 30 seconds does seem to work. I have however noticed that if you hit the Start button as soon as the game loads it won't preload the banner, and it take 30 seconds before the banner shows up on the game.

Edit: I just saw — post, I will try to implement a load screen for the banners. before the Main menu screen

Colludium No I don't, I just have preload banner at the start of layout and show banner ad bottom on the next layout. But I will add that to the events and see if it works any better. Thank you.

So is that from a Mopub or Admob comminucation error? When I download other apps they always have ads, Seems almost no point in having a paid version ad free, if my free games are ad free half the time lol

I have to actually open my app several times before I see the ad, and ideas?

This is what mine says

"Remember that this file can't be larger than 200 MB"

You export your game using the cocoonjs export option, it will create a zip file in the folder you exported it to. Just upload that file on the website. But you need to make sure your uploading the correct zip file.
