Add the Extension
The simplest way to install and manage your AIR native extensions and libraries is to use the AIR Package Manager (apm
). We highly recommend using apm
, as it will handle downloading all required dependencies and manage your application descriptor (Android manifest additions, iOS info additions etc).
However you can choose to install it manually, as you would have done in the past.
This ANE currently requires at least AIR 33+. This is required in order to support versions of Android > 9.0 (API 28). We always recommend using the most recent build with AIR especially for mobile development where the OS changes rapidly.
Install
- APM
- Manual
Note: All of the commands below should be run in a terminal / command prompt in the root directory of your application, generally the level above your source directory.
If you don't have an APM project setup, expand the guide below to setup an APM project before installing the extension.
Setup APM
Install APM
If you haven't installed apm
follow the install guide on airsdk.dev.
Setup an APM project
You will need an APM project for your application.
There are many ways to do this and for more options see the APM documentation. Here we will just initialise a new empty project:
apm init
Check your github token
We use github to secure our extensions so you must have created a github personal access token and configured apm
to use it.
To do this create a token using this guide from github and then set it in your apm config using:
apm config set github_token ghp_XXXXXXXXXXXXXXXXXXXXXXXXXXXX
If you don't do this correctly you may find the install will fail.
Install the extension
Install the extension by running:
apm install com.distriqt.GameServices
This will download and install the extension, required assets, and all dependencies.
Once complete apm
will have created something like the following file structure:
.
|____ ane
| |____ com.distriqt.GameServices.ane # GameServices extension
| |____ [dependencies]
|____ apm_packages # cache directory - ignore
|____ project.apm # apm project file
- Add the
ane
directory to your IDE. See the tutorials located here on adding an extension to your IDE.
We suggest you use the locations directly in your builds rather than copying the files elsewhere. The reason for this is if you ever go to update the extensions using apm
that these updates will be pulled into your build automatically.
- You will need to set some configuration items such as the Google Play Games application identifier. Call the following to step through the configuration values for this extension:
apm project config set com.distriqt.GameServices
The following guide is used to manually install the extension, download dependencies and update the application descriptor. We highly recommend installing extensions using apm
. Using apm
will automate the installation and automatically handle updates and dependencies along with greatly simplifying the application descriptor generation.
First step is always to add the extension to your development environment. Download the extension from the repository and then follow the tutorial located here to add the extension to your development environment.
Dependencies
Many of our extensions use some common libraries, for example, the Android Support libraries.
We have to separate these libraries into separate extensions in order to avoid multiple versions of the libraries being included in your application and causing packaging conflicts. This means that you need to include some additional extensions in your application along with the main extension file.
You will add these extensions as you do with any other extension, and you need to ensure it is packaged with your application.
Core
The Core extension is required by this extension. You must include this extension in your application.
This extension requires you call the init()
function at some point early in your application, generally at the same time as the initialisation of this extension. If you are using other extensions that also require the Core extension, you only need to initialise it once, before initialising the other extensions.
Core.init();
The Core extension doesn't provide any functionality in itself but provides support libraries and frameworks used by our extensions. It also includes some centralised code for some common actions that can cause issues if they are implemented in each individual extension.
You can access this extension here: https://github.com/distriqt/ANE-Core.
Application Descriptor
- APM
- Manual
Updating your application descriptor will insert the required extensionID
's and generate the manifest and info additions for your application.
You update your application descriptor by running:
apm generate app-descriptor src/MyApp-app.xml
Change the path (src/MyApp-app.xml
) to point to your application descriptor.
This will modify your application descriptor replacing the manifest additions and info additions with the ones generated from apm
.
You should backup your application descriptor before running this command to ensure you don't lose any information.
If you need to insert custom data into these sections see the guides for Android and iOS
iOS
If you are supporting saved games on Game Center then you must add the additional configuration for iCloud. You should do this before generating your application descriptor.
Firstly add a custom iOS configuration file by running:
apm generate config ios
This should produce config/ios/InfoAdditions.xml
and config/ios/Entitlements.xml
files alongside your project.
Edit the config/ios/Entitlements.xml
file to resemble the following:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<!-- GAME CENTER SAVED GAMES ADDITIONS -->
<!-- You only need the following lines if you are going to support GameCenter Saves -->
<key>com.apple.developer.ubiquity-container-identifiers</key>
<array>
<string>${iosContainerIdentifier}</string>
</array>
<key>com.apple.developer.ubiquity-kvstore-identifier</key>
<string>${iosKvstoreIdentifier}</string>
</dict>
</plist>
Then set the configuration values in your project by running:
apm project config set iosContainerIdentifier CONTAINER_IDENTIFIER
apm project config set iosKvstoreIdentifier KVSTORE_IDENTIFIER
The container identifier should be the container you created in Setup Game Center and the kvstore identifier should be your iOS team id followed by your application (bundle) id.
For example:
apm project config set iosContainerIdentifier iCloud.com.distriqt.test.testcontainer
apm project config set iosKvstoreIdentifier XXXXXXYYY.com.distriqt.test
Once you have added this configuration run the steps above to update / generate your application descriptor.
Note: Saved games are not supported on Apple tvOS. If you are supporting this platform you should not add the container to your application descriptor. If you are supporting both platforms and utilising saved games on iOS you will need to create separate projects for each and only add the above to the iOS application build.
Extension IDs
The following should be added to your extensions
node in your application descriptor to identify all the required ANEs in your application:
<extensions>
<extensionID>com.distriqt.GameServices</extensionID>
<extensionID>com.distriqt.Core</extensionID>
</extensions>
iOS
If you are supporting saved games on Game Center then you must add the additional
iCloud configuration lines, replacing the CONTAINER_IDENTIFIER
and YOUR_APPLICATION_IDENTIFIER
with your container identifier you created earlier.

If you are supporting both platforms and utilising saved games on iOS you will need to create separate application descriptors for each and only add the above to the iOS application build.
More information on creating your iCloud container can be found here: Setup GameCenter
Checking for Support
You can use the isSupported
flag to determine if this extension is supported on the current platform and device.
This allows you to react to whether the functionality is available on the device and provide an alternative solution if not.
if (GameServices.isSupported)
{
// Functionality here
}
