iOS

If your app is for iOS, you must also include the following code in build.settings to ensure that the native Facebook app functions properly:

settings = {

    iphone =
    {
        plist =
        {
            MinimumOSVersion = "7.0",
            UIApplicationExitsOnSuspend = false,
            FacebookAppID = "XXXXXXXXXX",  -- Replace XXXXXXXXXX with your Facebook App ID
            CFBundleURLTypes =
            {
                { CFBundleURLSchemes = { "fbXXXXXXXXXX", } }  -- Replace XXXXXXXXXX with your Facebook App ID
            },
            -- Whitelist Facebook apps
            LSApplicationQueriesSchemes =
            {
                "fb",  -- Needed for the facebook-v4.isFacebookAppEnabled() API
                "fbapi",
                "fbauth2",
                "fb-messenger-api",
                "fbshareextension"
            },
        }
    }
}

Notice that there are several critical parts which must be specified:

• MinimumOSVersion — Prevents your Facebook-enabled app from being installed on incompatible Apple devices.

• UIApplicationExitsOnSuspend — To ensure that Facebook can resume your app properly, you must include UIApplicationExitsOnSuspend = false. If you've set this parameter to true for some other reason, you must revert it to false (default).

• FacebookAppID — Set this key to FacebookAppID = "XXXXXXXXXX" and replace XXXXXXXXXX with your unique Facebook App ID.

• CFBundleURLTypes — The CFBundleURLTypes table must be declared exactly as shown and it must include a table named CFBundleURLSchemes. Inside this, include your Facebook App ID and prefix it with fb. Thus, if your App ID is 1234567890, you should specify: "fb1234567890".

• LSApplicationQueriesSchemes — This table of whitelisted URL schemes ensures that your app and the Facebook SDK run properly together.

Android

If your app is for Android, you must also include a Facebook App ID in build.settings:

settings = 
{
    android =
    {
        facebookAppId = "XXXXXXXXXX",  -- Replace XXXXXXXXXX with your Facebook App ID
    },
}

iOS

If you're using Corona Enterprise for iOS, you should ensure that the following static libraries are linked:

• libBolts.a

• libFBSDKCoreKit.a

• libFBSDKLoginKit.a

• libFBSDKShareKit.a

• libfacebook.a

In addition, you'll need to add several properties to your Info.plist. Open the file in an external text editor and add the following XML code into it:

<key>UIApplicationExitsOnSuspend</key>
<false/>
<key>FacebookAppID</key>
<!-- Replace XXXXXXXXXX with your Facebook App ID -->
<string>XXXXXXXXXX</string>
<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <!-- Replace XXXXXXXXXX with your Facebook App ID -->
            <string>fbXXXXXXXXXX</string>
        </array>
    </dict>
</array>
<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fb</string>
    <string>fbapi</string>
    <string>fbauth2</string>
    <string>fb-messenger-api</string>
    <string>fbshareextension</string>
</array>
<key>CoronaDelegates</key>
<array>
    <string>CoronaFacebookDelegate</string>
</array>

This has all of the same critical pieces as the build.settings additions for non-Enterprise implementation, plus the addition of the CoronaDelegates key with CoronaFacebookDelegate in its array. This allows Facebook login to work as well as suspending/resuming your app while Facebook is active.

Android

If you're using Corona Enterprise for Android, there are several configuration changes you'll need to make to your Android Studio project. Be sure to follow this procedure carefully as even minor mistakes can result in debugging headaches.

1. Locate the plugin binaries package that accommodates your build of Corona Enterprise, titled something like CoronaEnterprisePlugins.2016.2932.tgz, and copy only the "plugin.facebook.v4.jar" file into your project's "libs" directory.

2. Add the following permission to your AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET"/>

3. In the application element of your AndroidManifest.xml, add a meta-data tag containing your Facebook App ID.

<!-- Replace XXXXXXXXXX with your Facebook App ID -->
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="\ XXXXXXXXXX"/>

4. Similarly, add a meta-data tag containing the Display Name as posted in the Facebook Developer Portal. This can be found under Settings → Basic → Display Name.

<!-- Replace XXXXXXXXXX with your Facebook Display Name from the Facebook Developer Portal -->
<meta-data android:name="com.facebook.sdk.ApplicationName" android:value="XXXXXXXXXX"/>

5. Next, add the following activities to your AndroidManifest.xml:

<activity android:name="com.facebook.FacebookActivity"
        android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
        android:theme="@android:style/Theme.Translucent.NoTitleBar" />
<activity android:name="plugin.facebook.v4.FacebookFragmentActivity"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen" 
        android:configChanges="keyboardHidden|screenSize|orientation"/>

6. Download Corona's fork of the Facebook SDK for Android available here.

7. Link in the source code for the Facebook SDK via File → New → Import Module in Android Studio. Once you're at the New Module screen, select the [...] button next to the Source Directory field and browse to the downloaded Facebook SDK noted in the step above.

8. Find the facebook directory in the downloaded Facebook SDK. Confirm selection of that Gradle project and then click Finish on the New Module screen to import the Facebook SDK as a module for your Enterprise project.

9. In the downloaded Facebook SDK, locate the gradle.properties file in the root directory and copy its contents to your Android Studio project's gradle.properties file.

10. Back in Android Studio, open the build.gradle (Module: app) file and add this line to the bottom of the dependencies block:

compile project(':facebook')
