how to solve render problem Path.op() not supported?

Question

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:

Answer 1

I was facing the same problem. The reason is, that the new versions of Material Components are bundled with this bug. So, I tried replacing the version in the Gradle build script with the version that supports Path.op().

So, the only thing you have to do is replace the dependency in your Gradle build script with this one:

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

Answer 2

Problem solved by replacing the material component implementation in Gradle Build ( at App level )

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

to

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

Answer 3

Use the Experimental Rendering Engine, which solved the problem for me. First Suggested by Carlos.

Here is how to do it in android studio.

Go to File > Settings

Now the settings window will show up.
Go to the Experimental tab and check/tick Use new Layout Rendering Engine

That's it!

Answer 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.

Answer 5

A little late but

implementation 'com.google.android.material:material:1.2.0-alpha06'

works correctly, so no need to downgrade to alpha02 anymore.

Answer 6

Using the new Layout Rendering Engine helped fixing my problem. Go to Settings -> Experimental -> Use new Layout Rendering Engine
