Multiple strict mode violations when initializing Zoom Video SDK

mlewandowski · July 2, 2024, 1:10pm

Description
Zoom Video SDK initialization violates strict mode policies by performing multiple disk reads on the main thread. This results in app startup time and performance negatively affected.

Which Android Video SDK version?
1.12.0

To Reproduce(If applicable)
Steps to reproduce the behavior:

In your Application class, in onCreate() add following code:

StrictMode.setThreadPolicy(StrictMode.ThreadPolicy.Builder().detectAll().penaltyLog().build())

Run the app. Following logs appear in Logcat:
