ANR triggered by `com.tiktok.util.SystemInfoUtil` >>> `com.android.installreferrer` due to slow binder transactions.

[nightism]

Bug Description

We’re seeing a high number of ANRs caused by the TikTok Business SDK calling InstallReferrerClient.getInstallReferrer() (or similar synchronous methods) on the main thread. These methods make Binder calls to Google Play Services, which can block the thread and trigger ANRs.

A similar issue has been reported in the Facebook SDK: facebook/facebook-android-sdk#1039

Configuration

We have configured the TikTok Business SDK by following the official documentation: https://business-api.tiktok.com/portal/docs?id=1739585434183746
