Code samples & details

Facing the same issue. I have only recently used the latest sdk to integrate login. Would downgrading to an old version fix this?

same question when I update AGP to 8.10.0, can receive this bug in firebase

[SzGajdzica]

I Added this code to manifest, will give you feedback if that helps after app update is released <meta-data android:name="com.facebook.sdk.AutoLogAppEventsEnabled" android:value="false"/>

@SzGajdzica did it fix the crash?

[SzGajdzica]

No, but i found another solution that completly fixes this issue! Just add this to the proguard -keepclassmembernames class com.facebook.appevents.ondeviceprocessing.** { java.util.concurrent.CountDownLatch *; }

[kk-atom]

Dont close issue. SDK should be fixed.

[SzGajdzica]
