Facebook Audience 6.2.0 /apex/com.android.art/lib64/libart.so (art::OatHeader::IsDebuggable() const+124) on Android 11

Question

After updating to Facebook Audience 6.2.0 from 5.11.0 on an Android app with target SDK 29 I'm seeing a considerable amount of crash reports on a small percentage of Android 11 devices. According to a user that is having this crash and has reinstalled the app several times to test, the crash occurs a few seconds after startup being able to see a loading screen the first time and then immediately after that first time.

This is different from the /apex/com.android.runtime/lib64/bionic/libc.so (abort+160) issue (/apex/com.android.runtime/lib64/bionic/libc.so (abort+160), abort crash in Android 10 devices) which still rarely occurs on 6.2.0.

Answer 1

According to the change log, version 6.2.1 (published on 03Feb2021) of the Android Facebook Audience Network SDK fixes this bug.
