Users may see the domain of passwords stored with the Password AutoFill feature as airbridge.io or abr.ge.

After setting up deep links for the Airbridge SDK, if you utilize the Password AutoFill feature, the domain is saved as the applinks domain of the Airbridge deep link, which is airbridge.io or abr.ge.

The problem can be solved by setting up the webcredentials domain used in the Password AutoFill.

1. Prepare the domain that will store the password.

2. Host the JSON below at https://YOUR_DOMAIN/.well-known/apple-app-site-association with Content-Type: application/json. Your prepared domain should be entered instead of YOUR_DOMAIN.

You can find the App ID Prefix and Bundle ID in the [Identifiers]>[YOUR_APP] menu of the Apple Developer Portal.

3. Navigate to [YOUR_PROJECT]>[Signing & Capabilities] in Xcode.

4. Click + Capability to add Associated Domains. Enter webcredentials:YOUR_DOMAIN in Associated Domains.

Upon uploading the app to the App Store, Xcode displays a warning message that a dSYM for the Airbridge framework was not included.

The Airbridge iOS SDK does not support dSYM.

The dSYM will be supported in the coming update. You may ignore this warning.

A coroutine dependency error occurs during the build process with the following message.

If the kotlinx-coroutines-core library version is 1.3.5 or later, the kotlin-stdlib library version must be at a certain level or later.

Check whether the kotlin-stdlib library version is v.1.3.70 or later with the gradlew dependencies command. If the version is earlier than v.1.3.70, you need to update it.

Deeplink Open events that occur through the push notifications generated by the Braze SDK are not collected by Airbridge. Instead, the App Open event is collected.

The Airbridge Android SDK uses the dataString in the action and intent of the Activity to distinguish between Deeplink Open events and App Open events.

When a user opens the app through a push notification using the Braze SDK, the app goes through NotificationTrampolineActivity. This activity handles push notifications, but the dataString is not included in its action and intent, preventing the SDK from determining if it's a Deeplink Open event or an App Open event.

Add a custom Application class (CustomApplication.java) file as shown below.

Add a custom application class to the Android Manifest file using Unreal Plugin Language (UPL), as shown below.

The "Manifest merger failed" error occurrs during the build process.

The Airbridge SDK's AndroidManifest.xml includes rules to opt-out of backing up the Shared Preferences data. The purpose of this rule is to avoid retaining the same Airbridge settings during the reinstallation of the app so that new installs or reinstalls can be detected accurately.

Merging Airbridge SDK backup rules with your app backup rules can cause conflicts.

Below are the opt-out rules defined in the Airbridge SDK.

Adding android:fullBackupContent="string" to the AndroidManifest.xml may cause an error like the following.

To fix this error,

• add xmlns:tools="http://schemas.android.com/tools" in the Platforms > Android > Extra Tags for <manifest> node to the Unreal Editor Project Settings window.

• add tools:replace="android:fullBackupContent" in the Platforms > Android > Extra Tags for <application> node to the Unreal Editor Project Settings window.

Adding android:dataExtractionRules="string resource" to the AndroidManifest.xml may cause an error like the following.

To fix this error,

• add xmlns:tools="http://schemas.android.com/tools" to the Platforms > Android > Extra Tags for <manifest> node in the Unreal Editor Project Settings window.

• add tools:replace="android:dataExtractionRules" to the Platforms > Android > Extra Tags for <application> node in the Unreal Editor Project Settings window.

If you add android:allowBackup="false" in the AndroidManifest.xml, you might get the following error:

To fix this error,

• add xmlns:tools="http://schemas.android.com/tools" to the Platforms > Android > Extra Tags for <manifest> node in the Unreal Editor Project Settings window.

• add tools:replace="android:allowBackup" to the Platforms > Android > Extra Tags for <application> node in the Unreal Editor Project Settings window.

The android:dataExtractionRules has been added in API Level 31. Therefore, if the compileSdkVersion is lower than 31, an error like the following may occur.

To fix this error,

• add xmlns:tools="http://schemas.android.com/tools" to the Platforms > Android > Extra Tags for <manifest> node in the Unreal Editor Project Settings window.

• add tools:remove="android:dataExtractionRules" to the Platforms > Android > Extra Tags for <application> node in the Unreal Editor Project Settings window.

If an Airbridge SDK backup rule and a backup rule for a different third-party SDK (e.g., AppsFlyer SDK) overlap, you will see the build error below.

Overlapping of the Airbridge SDK backup rules and third-party SDK backup rules can cause build errors.

1. Create a file (e.g., custom_backup_rules.xml) within the module directory.

2. Add the data backup rules defined by the Airbridge SDK as follows.

   <?xml version="1.0" encoding="utf-8"?><full-backup-content> <!-- Airbridge Backup Rules --> <exclude domain="sharedpref" path="airbridge-internal" /> <exclude domain="sharedpref" path="airbridge-install" /> <exclude domain="sharedpref" path="airbridge-user-info" /> <exclude domain="sharedpref" path="airbridge-user-alias" /> <exclude domain="sharedpref" path="airbridge-user-attributes" /> <exclude domain="sharedpref" path="airbridge-device-alias" /> <exclude domain="database" path="airbridge.db" /> <!-- Appsflyer Backup Rules --> <exclude domain="sharedpref" path="appsflyer-data"/> <!-- Your Custom Backup Rules --></full-backup-content>

3. Using the Unreal Plugin Language (UPL), copy the file into your res/xml folder as follows.

   <?xml version="1.0" encoding="utf-8"?><root xmlns:android="http://schemas.android.com/apk/res/android"> ... <resourceCopies> <copyFile src="{YOUR_XML_BACKUP_RULES_PATH}" dst="$S(BuildDir)/res/xml/custom_backup_rules.xml" /> ... </resourceCopies> ...</root>

1. Create a file (e.g., custom_data_extraction_rules.xml) within the module directory.

2. Add the data backup rules defined by the Airbridge SDK as follows.

   <?xml version="1.0" encoding="utf-8"?><data-extraction-rules> <cloud-backup> <!-- Airbridge Backup Rules --> <exclude domain="sharedpref" path="airbridge-internal" /> <exclude domain="sharedpref" path="airbridge-install" /> <exclude domain="sharedpref" path="airbridge-user-info" /> <exclude domain="sharedpref" path="airbridge-user-alias" /> <exclude domain="sharedpref" path="airbridge-user-attributes" /> <exclude domain="sharedpref" path="airbridge-device-alias" /> <exclude domain="database" path="airbridge.db" />  <!-- Appsflyer Backup Rules --> <exclude domain="sharedpref" path="appsflyer-data"/>  <!-- Your Custom Backup Rules --> </cloud-backup> <device-transfer> <!-- Airbridge Backup Rules --> <exclude domain="sharedpref" path="airbridge-internal" /> <exclude domain="sharedpref" path="airbridge-install" /> <exclude domain="sharedpref" path="airbridge-user-info" /> <exclude domain="sharedpref" path="airbridge-user-alias" /> <exclude domain="sharedpref" path="airbridge-user-attributes" /> <exclude domain="sharedpref" path="airbridge-device-alias" /> <exclude domain="database" path="airbridge.db" />  <!-- Appsflyer Backup Rules --> <exclude domain="sharedpref" path="appsflyer-data"/>  <!-- Your Custom Backup Rules --> </device-transfer></data-extraction-rules>

3. Using the Unreal Plugin Language (UPL), copy the file into your res/xml folder as follows.

   <?xml version="1.0" encoding="utf-8"?><root xmlns:android="http://schemas.android.com/apk/res/android"> ... <resourceCopies> <copyFile src="{YOUR_XML_BACKUP_RULES_PATH}" dst="$S(BuildDir)/res/xml/custom_data_extraction_rule.xml" /> ... </resourceCopies> ...</root>

In the Unreal Editor Project Settings window, add the following element to the Platforms - Android > Advanced APK Packaging > Extra Tags for <manifest> node.

• xmlns:tools="http://schemas.android.com/tools"

In the Unreal Editor Project Settings window, add the following elements to the Platforms - Android > Advanced APK Packaging > Extra Tags for <application> node.

• android:allowBackup="true"

• android:fullBackupContent="@xml/custom_backup_rules"

• android:dataExtractionRules="@xml/custom_data_extraction_rules"

• tools:replace="android:fullBackupContent, android:dataExtractionRules"

When uploading your app to Google Play Console, you may receive the following warning or rejection messages:

• "Your app doesn't support 16 KB page size"

• "16 KB page size compatibility required"

• App upload is rejected or displayed in a warning state

This is due to Google Play policy requirements that apps targeting Android 15 (API level 35) or higher must support 16KB page size.

Airbridge SDK supports 16KB page size from the following versions:

However, SDK support alone is not sufficient. The entire app (APK/AAB) must be packaged with 16KB zipalign to pass Google Play policy.

If APK/AAB is not built with 16KB zipalign:

• You will receive warning or rejection messages when uploading to Google Play Console

• Uploads will be completely blocked after November 1, 2025

• The app may not work properly on 16KB page size devices in the future

Step 1: Check Airbridge SDK Version

First, verify that your Airbridge SDK version supports 16KB. If you are using an older version, you must update to the latest version.

Step 2: Check and Configure Android Gradle Plugin (AGP) Version

Check your project's current AGP version.

If using AGP 8.5.1 or higher:

• 16KB zipalign is automatically applied without any additional configuration.

• Proceed directly to Step 3.

If using AGP 8.5.0 or lower:

• Option A: Upgrade AGP to 8.5.1 or higher

• Option B: Keep current AGP version + Add configuration

  android { ... packagingOptions { jniLibs { useLegacyPackaging true } }}

Step 3: Rebuild and Verify the App

After changing the configuration, perform a clean build of your app.

Step 4: Verify 16KB zipalign Application

Verify that the built APK/AAB is properly 16KB zipaligned.
