ConstraintLayout version: 2.0.0 beta 6

Couple of issues with customBoolean:

It's called way too many times, in my example 17 times, while boolean only can be in 2 states: true or false. It should have been called only 2 times when transition starts and when transition ends.
Right before last change it changes back to false then back to true:

I/System.out: CustomLayout.setEnabled=false
I/System.out: CustomLayout.setEnabled=false
I/System.out: CustomLayout.setEnabled=false
I/System.out: CustomLayout.setEnabled=false
I/System.out: CustomLayout.setEnabled=false
I/System.out: CustomLayout.setEnabled=false
I/System.out: CustomLayout.setEnabled=false
I/System.out: CustomLayout.setEnabled=false
I/System.out: CustomLayout.setEnabled=false
I/System.out: CustomLayout.setEnabled=false
I/System.out: CustomLayout.setEnabled=true
I/System.out: CustomLayout.setEnabled=true
I/System.out: CustomLayout.setEnabled=true
I/System.out: CustomLayout.setEnabled=true
I/System.out: CustomLayout.setEnabled=true
I/System.out: CustomLayout.setEnabled=true
I/System.out: CustomLayout.setEnabled=false   <--- why?
I/System.out: CustomLayout.setEnabled=true

This is likely due to an incorrect service loader specified somewhere.

If you are unable to fix the server loader spec, you can add a -dontwarn rule for the class to silence the error using:

-dontwarn com.google.protobuf.java_com_google_android_gmscore_sdk_target_granule__proguard_group_gtm_N1281923064GeneratedExtensionRegistryLite$Loader

Could you see which service file the class is declared in? You will need to look for the class referenced META-INF/services/<somefile>.

Alternatively you can create a compiler input dump and attach in public here or privately with zerny@google.com and/or mkroghj@google.com and we can find the service info in that.
