How to solve this error: Render problem Path.op() not supported

I tried to force refresh layout, restart, update Android Studio, stop antivirus for a while, but the problem is still there.

Surprisingly I am able to compile and run the app, but how to get rid of this error?

I am using:

• Android Studio 3.5.3
• Android SDK Tools 29.0.2
• Android SDK Platform Android 10.0 (Q) Android SDK Platform 29
• Default OpenJDK Platform binary

to reproduce the error:

• Create new Android project with empty activity

• replace the layout with the following layout:

  <?xml version="1.0" encoding="utf-8"?>    <androidx.coordinatorlayout.widget.CoordinatorLayout

回答1:

I was facing the same problem. The thing is, the newsty version of material components are with this bug. What i did to solve was replacing the version in Build Gradle, at the app level, to the version that supports Path.op().

So, the only thing you have to do is replace the implementation of material in your gradle for this one:

implementation 'com.google.android.material:material:1.2.0-alpha02'

回答2:

problem solved by changing

com.google.android.material:material:1.2.0-alpha05

to

com.google.android.material:material:1.2.0-alpha02

回答3:

I faced the same problem. The problem improved when I run the application. I think the problem will be improved when you clear and rebuild your project.

回答4:

I bumped into the same problem yesterday. Mine got to do with the

com.google.android.material.appbar.AppBarLayout

component. I do not know exactly why, but adding android:background="..." solves it.

回答5:
