This explains how to solve build errors caused by overlapping of the Airbridge SDK backup rules and third-party SDK backup rules.
e.g. If you have an Airbridge SDK backup rule and an Appsflyer SDK backup rule that overlap.
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.Create a src/main/res/xml folder.
Within the created xml folder, create a file (e.g. custom_backup_rules.xml).
Add the data backup rules defined in 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" />
