Hope you are well. I want to add iMessage Stickers to my app. My app created in Android Studio using LibGDX/RoboVM. So, I can't add Stickers extension directly to my project. I have signed .ipa as output from Android Studio after building with RoboVM. I have created a single standalone project in Xcode with my app's bundle id, added the Stickers extension, then have done the following.
In the terminal
- Unzipped the .ipa using "unzip MyApp.ipa".
- Removed the _CodeSignature folder using "rm -rf Payload/MyApp.app/_CodeSignature/"
- Copied and Pasted the Stickers extension to the "Payload/MyApp.app/"
- Copied and Pasted the provisioning profile using "cp MyDistributionProfile.mobileprovision Payload/MyApp.app/embedded.mobileprovision"
- Signed again using "codesign -f -s "iPhone Distribution: MyCompany INC" --entitlements Entitlements.plist Payload/MyApp.app"
- Zipped using "zip -qr MyResignedApp.ipa Payload/".
After this, I tried to upload the MyResignedApp.ipa via ApplcationLoader from XCode and did not get any error during upload.
The problem is that I received the rejection email, where they said the following,
This bundle is invalid - The Info.plist file for /Payload/MyApp.app/Sticker Pack.stickerpack is missing or could not be read.
The Info.plist exists and here is it.

Any suggestions what I'm doing wrong? Many Many thanks.
You `Copied and Pasted the Stickers extension to the "Payload/MyApp.app/" but extension has to be located in "Payload/MyApp.app/PlugIns".
MobiVM natively supports packing and signing extension out of the box. And it is not required to manual repacking/signing.
But you have to build app extension in Xcode within standalone project, then reference extension in robovm.xml like bellow:
<appExtensions>
<extension profile="3AED05A9-5F1F-4120-9276-11980B9C88EE">OneSignalNotificationServiceExtension</extension>
</appExtensions>
To build it in Xcode easies way is to add extension target to empty project. Then build it separately from command line using xcode-build:
xcodebuild -project onesignal.xcodeproj -target OneSignalNotificationServiceExtension -configuration release -sdk iphoneos -arch arm64 -arch armv7 -arch armv7s BUILD_DIR=build BUILD_ROOT=build
xcodebuild -project onesignal.xcodeproj -target OneSignalNotificationServiceExtension -configuration release -sdk iphonesimulator -arch i386 -arch x86_64 BUILD_DIR=build BUILD_ROOT=build
and pack into fat binary using lipo.
lipo -create -output "OneSignalNotificationServiceExtension.appex/OneSignalNotificationServiceExtension" \
"build/release-iphoneos/OneSignalNotificationServiceExtension.appex/OneSignalNotificationServiceExtension" \
"build/release-iphonesimulator/OneSignalNotificationServiceExtension.appex/OneSignalNotificationServiceExtension"
Also in case of stickers extension RoboVM copies following to IPA:
Which might be missing when you do repacking manually.
There is a tutorial for MobiVM how to use app extension which provide more details about each step.
