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.
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.
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:
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.Image
This will download and install the extension, required assets, and all dependencies.
apm will have created something like the following file structure:
| |____ com.distriqt.Image.ane # IDFA extension
| |____ [dependencies]
|____ apm_packages # cache directory - ignore
|____ project.apm # apm project file
- Add the
anedirectory 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.
- For iOS you will need to set the usage description for the authorisation dialog to allow you to save to the user's camera roll. You can leave them as the defaults if you wish. Call the following to step through the configuration values for this extension:
apm project config set com.distriqt.Image
The following guide is used to manually install the extension, download dependencies and update the application descriptor. We highly recommend installing extensions 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.
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.
The Core ANE is required by this ANE. You must include and package this extension in your application.
The Core ANE 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.
The Android Support libraries encompass the Android Support, Android X and common Google libraries.
These libraries are specific to Android. There are no issues including these on all platforms, they are just required for Android.
This extension requires the following extensions:
You can access these extensions here: https://github.com/distriqt/ANE-AndroidSupport.
Note: if you have been using the older
com.distriqt.androidsupport.*(Android Support) extensions you should remove these extensions and replace it with the
androidxextensions listed above. This is the new version of the android support libraries and moving forward all our extensions will require AndroidX.
Note: The Google Play Services and Android Support ANEs are only required on Android devices. There are no issues packaging these extensions with all platforms as there are default implementations available which will allow your code to package without errors however if you are only building an iOS application feel free to remove the Google Play Services and Android Support ANEs from your application.
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
You should backup your application descriptor before running this command to ensure you don't lose any information.
The following should be added to your
extensions node in your application descriptor to identify all the required ANEs in your application:
In order for the extension to request permissions to save images to the camera roll you must add the following to your manifest additions:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<activity android:name="com.distriqt.core.auth.AuthorisationActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar" android:exported="false" />
The following additions are for the
InfoAdditions node of the iPhone section in your application descriptor:
If you are using iOS 10+ you now need to add some strings to display messages to the user when certain permissions are requested. If you are sharing images then there is a chance the user may select to save to their camera roll in which case the following is displayed the first time your user attempts to access the camera roll.
There are 2 keys required here that control the text in this dialog:
<string>Access to photo library is required to save images.</string>
<string>Access to photo library is required to save images.</string>
The second key was added in iOS 11.2. You should add both keys to your info additions.
Checking for Support
You should check whether the extension is supported before making calls with the
This allows you to react to whether the functionality is available on the device.
We always implement this function to allow you to dynamically switch functionality and fallback to other methods if the extension is not supported on the current platform and version.
