EDIT: SOLUTION IN THE ANSWER
I just uploaded an application made in libgdx on itunes connect , and my problem is that I get this email :
Dear developer,
We have discovered one or more issues with your recent delivery for "Surf Survivor". Your delivery was successful, but you may wish to correct the following issues in your next delivery:
Missing recommended icon file - The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format for iOS versions >= 7.0.
Missing recommended icon file - The bundle does not contain an app icon for iPad of exactly '76x76' pixels, in .png format for iOS versions >= 7.0.
Missing recommended icon file - The bundle does not contain an app icon for iPad of exactly '152x152' pixels, in .png format for iOS versions >= 7.0.
After you’ve corrected the issues, you can use Xcode or Application Loader to upload a new binary to iTunes Connect.
