AAPT: error: resource attr/flow_horizontalSeparator not found

[ehaahe]

When i migrate android.support to androidx,it is not working with this error,how can i resolve it? the version of ConstrainLayout is 2.0.0-beta2

[zskamljic]

Getting the same issue on a project that was on androidx since the beginning

[banshee]

Did you update to gradle 3.6 alpha? Try changing back - do classpath 'com.android.tools.build:gradle:3.5.0-beta05' That fixed it for me.

This is the relevant issue in the Google tracker https://issuetracker.google.com/issues/136103084

The recommendation for now is to either:

• Downgrade Android Studio (3.6 alpha 2 works fine for me, alpha 3 creates this issue with ConstraintLayout 2 or any other library that uses attrs the old way)
• Add the attrs that are missing to your project. When another version of ConstraintLayout library is released with the attrs included you'll have to remove them from your project.

I get the same issue. I hope fixed as soon as possible, I use android studio 3.6 Canary 4 , gradle:3.6.0-alpha04, ConstrainLayout is 2.0.0-beta2

How do i Downgrade Android Studio? Is there a function in it?

The same thing happened to me with android studio 3.6 canary 5 and what I did was to make a clean installation and it worked well

Still encountering this issue

[Bill1550]

Still encountering this issue with ConstraintLayout 2.0.0-beta1 and build tools 3.6.0-rc02

[mrv96]

I solved the issue using the automatic migration tool to AndroidX. After the automatic refactor, the project works fine with gradle plugin 3.6.0. No manual code modification was required.
