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.

{
    "webcredentials": {
        "apps": ["YOUR_APP_ID_PREFIX.YOUR_BUNDLE_ID"]
    }
}

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

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

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

java.lang.NoClassDefFoundError: kotlin/coroutines/AbstractCoroutineContextKey
    at java.base/java.lang.ClassLoader.defineClass1(Native Method)
    at java.base/java.lang.ClassLoader.defineClass(ClassLoader.java:1016)
  ...

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.

package com.company.product;

import android.app.Activity;
import android.app.Application;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;

import co.ab180.airbridge.AirbridgeLifecycleIntegration;
import co.ab180.airbridge.unity.AirbridgeUnity;

public class CustomApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        AirbridgeUnity.setLifecycleIntegration(new AirbridgeLifecycleIntegration() {

            @Nullable
            @Override
            public String getDataString(@NonNull Activity activity) {
                if (activity.getClass().getName().equals("com.braze.push.NotificationTrampolineActivity")
                        && activity.getIntent() != null
                        && activity.getIntent().getExtras() != null
                ) {
                    return activity.getIntent().getExtras().getString("uri");
                }
                return null;
            }
        });
    }
}

Add the custom Application class to the Custom Main Manifest (Assets/Plugins/Android/AndroidManifest.xml) file as shown below.

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
  
  <application android:name="com.company.product.CustomApplication"
    android:theme="@style/UnityThemeSelector"
    android:icon="@mipmap/app_icon"
    android:label="@string/app_name">

    ...

  </application>
</manifest>

The "Manifest merger failed" error occurs 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.

<?xml version="1.0" encoding="utf-8"?>
<data-extraction-rules>
    <cloud-backup>
        <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" />
    </cloud-backup>
    <device-transfer>
        <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" />
    </device-transfer>
</data-extraction-rules>

<?xml version="1.0" encoding="utf-8"?>
<full-backup-content>
    <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" />
</full-backup-content>

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

Manifest merger failed : Attribute application@fullBackupContent value=(string) from AndroidManifest.xml

To fix this error,

• add xmlns:tools="http://schemas.android.com/tools" to the <manifest> tag

• add tools:replace="android:fullBackupContent" to the <application> tag

in the Custom Main Manifest(Assets/Plugins/Android/AndroidManifest.xml) file.

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

Manifest merger failed : Attribute application@dataExtractionRules value=(string resource) from AndroidManifest.xml

To fix this error,

• add xmlns:tools="http://schemas.android.com/tools" to the <manifest> tag

• add tools:replace="android:dataExtractionRules" to the <application> tag

in the Custom Main Manifest(Assets/Plugins/Android/AndroidManifest.xml) file.

Adding android:allowBackup="false" to the AndroidManifest.xml file may cause an error like the following.

Manifest merger failed : Attribute application@allowBackup value=(false) from AndroidManifest.xml:32:9-36
	is also present at [:airbridge] AndroidManifest.xml:27:9-35 value=(true).
	Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:30:5-250:19 to override.

To fix this error,

• add xmlns:tools="http://schemas.android.com/tools" to the <manifest> tag

• add tools:replace="android:allowBackup" to the <application> tag

in the Custom Main Manifest(Assets/Plugins/Android/AndroidManifest.xml) file.

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.

AndroidManifest.xml: AAPT: error: attribute android:dataExtractionRules not found.

To fix this error,

• add xmlns:tools="http://schemas.android.com/tools" to the <manifest> tag

• add tools:remove="android:dataExtractionRules" to the <application> tag

in the Custom Main Manifest(Assets/Plugins/Android/AndroidManifest.xml) file.

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.

Attribute application@fullBackupContent value=(@xml/appsflyer_backup_rules) from [com.appsflyer:af-android-sdk:6.6.1] AndroidManifest.xml:14:18-73
is also present at [io.airbridge:sdk-android:2.14.0] AndroidManifest.xml:27:18-78 value=(@xml/airbridge_auto_backup_rules).
Suggestion: add 'tools:replace="android:fullBackupContent"' to <application> element at AndroidManifest.xml:7:5-13:19 to override.

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

1. Create an Android Library project (Assets/Plugins/Android/res.androidlib) to store your resource files.

2. Add an AndroidManifest.xml file in the created Android Library Project as follows.

   123456

   <?xml version="1.0" encoding="utf-8"?>
   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
             package="custom.android.res"
             android:versionCode="1"
             android:versionName="1.0">
   </manifest>

3. Create a res/xml folder inside the created Android Library Project.

4. Create a file (e.g., custom_backup_rules.xml) within the new xml folder.

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

   12345678910111213141516

   <?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>

1. Create a file (e.g., custom_data_extraction_rules.xml) within the new xml folder.

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

   123456789101112131415161718192021222324252627282930313233

   <?xml version="1.0" encoding="utf-8"?>

           <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" />

   	    <!-- Your Custom Backup Rules -->
       </device-transfer>
   </data-extraction-rules>

Apply the data backup rules to the Android App Manifest file (Assets/Plugins/Android/AndroidManifest.xml) as follows.

<manifest
    ...
    xmlns:tools="http://schemas.android.com/tools">

    <application
        ...
		android:allowBackup="true"
		android:fullBackupContent="@xml/custom_backup_rules"
        android:dataExtractionRules="@xml/custom_data_extraction_rules"
		tools:replace="android:fullBackupContent, android:dataExtractionRules">
