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.
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 io.branch.nativeExtensions.Branch
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
| |____ io.branch.nativeExtensions.Branch.ane # Branch 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 the usage description strings for use in the authorisation dialogs. Call the following to step through the configuration values for this extension:
apm project config set com.distriqt.BluetoothLE
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 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.
Android Support
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 theandroidx
extensions listed above. This is the new version of the android support libraries and moving forward all our extensions will require AndroidX.
Google Play Services
This ANE requires can use of certain aspects of the Google Play Services if supplied, mainly around using the advertising identifier to attribute links correctly.
The client library is available as a series of ANEs that you add into your applications packaging options. Each separate ANE provides a component from the Play Services client library and are used by different ANEs. These client libraries aren't packaged with this ANE as they are used by multiple ANEs and separating them will avoid conflicts, allowing you to use multiple ANEs in the one application.
If you wish to use the expanded functionality add the following Google Play Services:
You can access the Google Play Services client library extensions here: https://github.com/distriqt/ANE-GooglePlayServices.
Note: The Google Play Services and Android Support ANEs are only required on Android devices. There is no problem packaging these ANEs 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 ANEs from your application.
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
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>io.branch.nativeExtensions.Branch</extensionID>
<extensionID>com.distriqt.Core</extensionID>
<extensionID>androidx.core</extensionID>
<extensionID>androidx.appcompat</extensionID>
<extensionID>androidx.browser</extensionID>
<extensionID>com.android.installreferrer</extensionID>
<extensionID>com.distriqt.playservices.Base</extensionID>
<extensionID>com.distriqt.playservices.AdsIdentifier</extensionID>
</extensions>
Android
Manifest Additions
There are several additions to the manifest required for the Branch extension. In order to correctly gather install referrer information you need to add the com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE
permission :
<uses-permission android:name="com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE" />
<application>
</application>
Keys
Most importantly you need to add the Branch keys for your application as meta data tags to the application
node in your manifest:
<meta-data android:name="io.branch.sdk.TestMode" android:value="false" />
<meta-data android:name="io.branch.sdk.BranchKey" android:value="key_live_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" />
<meta-data android:name="io.branch.sdk.BranchKey.test" android:value="key_test_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" />
The io.branch.sdk.TestMode
flag can be used to set your application into test mode from the manifest. You can override this in your AS3 code however this option is here if you wish to use this method.
Deep link scheme
If you are adding a deep link / custom url scheme to be able to launch your application from a url such as myapp://
then you need to add the scheme to the main activity for your application:
<activity android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<!-- Branch URI scheme -->
<intent-filter>
<data android:scheme="myapp" android:host="open" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>
Example
<android>
<manifestAdditions><![CDATA[
<manifest android:installLocation="auto">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE" />
<application>
<activity android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<!-- Branch URI scheme -->
<intent-filter>
<data android:scheme="myapp" android:host="open" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>
<meta-data android:name="io.branch.sdk.TestMode" android:value="true" />
<meta-data android:name="io.branch.sdk.BranchKey" android:value="key_live_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" />
<meta-data android:name="io.branch.sdk.BranchKey.test" android:value="key_test_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" />
</application>
</manifest>
]]></manifestAdditions>
</android>
iOS
The Branch SDK requires a few additions to the Info plist and Entitlements section of your application to correctly configure your application. These are listed in the sections below.
Note: As of version 3.1 the extension now packages the Branch iOS framework code internal to the application. You no longer need to add the Framework.
Keys
Most importantly you need to add the Branch keys for your application to the InfoAdditions node:
<key>branch_key</key>
<dict>
<key>live</key>
<string>key_live_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</string>
<key>test</key>
<string>key_test_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</string>
</dict>
You should replace the entries above with the values from the Branch dashboard for your application.
Configure associated domains
Add your link domains from your Branch dashboard, these should be added to the Entitlements node, for example:
<key>com.apple.developer.associated-domains</key>
<array>
<string>applinks:ap8q.test-app.link</string>
<string>applinks:ap8q-alternate.test-app.link</string>
</array>
Deep link scheme
If you are adding a deep link / custom url scheme to be able to launch your application from a url such as myapp://
then you need to add the scheme to the info additions as below:
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>myapp</string>
</array>
</dict>
</array>
Example
<iPhone>
<InfoAdditions><![CDATA[
<key>UIDeviceFamily</key>
<array>
<string>1</string>
<string>2</string>
</array>
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>myapp</string>
</array>
</dict>S
</array>
<key>branch_key</key>
<dict>
<key>live</key>
<string>key_live_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</string>
<key>test</key>
<string>key_test_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</string>
</dict>
]]></InfoAdditions>
<requestedDisplayResolution>high</requestedDisplayResolution>
<Entitlements><![CDATA[
<key>com.apple.developer.associated-domains</key>
<array>
<string>applinks:ap8q.test-app.link</string>
<string>applinks:ap8q-alternate.test-app.link</string>
</array>
]]></Entitlements>
</iPhone>
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 (BluetoothLE.isSupported)
{
// Functionality here
}
