coroutine crash: java.lang.NoSuchFieldException:_decision

[boyan01]

I'm using Kotlin coroutine 1.3.4, and my app is obfuscated. some user's device got a crash:

java.lang.NoSuchFieldException:_decision
at java.lang.Class.getDeclaredField(Class.java:929)
at java.util.concurrent.atomic.AtomicIntegerFieldUpdater$AtomicIntegerFieldUpdaterImpl.<init>(AtomicIntegerFieldUpdater.java:251)

at v.a.q2.b.a(CoroutineScheduler.kt:39)
at v.a.q2.b$a.run(CoroutineScheduler.kt:12)

According to the mapping file. the real call stack is

 java.lang.NoSuchFieldException:_decision

it is necessary to keep _decision field of DispatchedCoroutine?
build

• classpath 'com.android.tools.build:gradle:3.5.3'

Yes, it is, please check your proguard rules.
If your rules are in order, but some users still see the crash, it's likely to be an Android-specific issue and it's worth reporting to Google issue tracker
