I can't repro this. Are you using a custom style?

Could you share a sample app reproing this issue

[fllaryora]

Hi @ymarian
My styles.xml is `

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

`

And I am using a FAB like :
<com.google.android.material.floatingactionbutton.FloatingActionButton android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" app:backgroundTint="@android:color/white" app:layout_anchor="@+id/card_view" android:tint="@color/colorPrimary" android:src="@drawable/ic_arrow_right" app:rippleColor="@color/colorCard" app:layout_anchorGravity="right|end|center_vertical" />

materialVersion = '1.2.0-alpha05'

[ProDev2]

I'm getting the same error in Android Studio's layout editor window, when using 'materialVersion=1.2.0-alpha05' like @fllaryora mentioned before me. But no crash when running.

[wcshi]

Just to clarify, is this a problem that only happens in Android Studio's layout editor preview? And not in an actual app?

[Spazzze]

Same for me. Unfortunately with latest build (alpha06) problem is still here.
Yes, it is only with layout editor preview, and reproduces with any fab no matter what else in xml, I tried with 'com.google.android.material:material:1.2.0-alpha05' and 'com.google.android.material:material:1.2.0-alpha06' - problem exists. With 'com.google.android.material:material:1.2.0-alpha02' - no problem.
My AS info

Android Studio 3.6.2
Build #AI-192.7142.36.36.6308749, built on March 18, 2020
Runtime version: 1.8.0_212-release-1586-b04 amd64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o

At editor there is 2 issues, one is described by issue starter, second is

Path.op() not supported Tip: Try to refresh the layout.

And fab looks like crap:

Could you please check whether the issue is still reproducible in Android Studio 4.x? If yes, please file a bug with the Studio team using this public issue tracker:

no I cant because AS 3.6.2 is latest stable build and I wont install version from canary channel it can affect my work.

@wcshi I can confirm it works perfectly with Android Studio 4.0 beta 4. It was not working on AS 3.6

[Fauzdar1]

Facing same issue with TextInputLayout in alpha-06. Only one TextInputLayout is visible in the layout editor at a time and if I change any value in other invisible ones, that becomes visible and others go invisible, works like a visibility toggle. Very strange issue. In device, it seems perfect though, but I've to render the app in my device every time to see the theme changes. Also, any other material element like buttons do the same behaviour, if they're constrained with any invisible one, they go invisible too.
Mine shows three errors:Path.op() not supported, Layout fidelity warning and missing initial moveTo in path definition

[Fauzdar1]

I resolved my problem of invisible TextInputLayout, though. Setting BoxStrokeWidth as 0dp to hide the activation indicator is the issue but I'll go with this as as I want to hide it in the Filled mode. But, the errors remain intact.

I'm facing this issue also with Android studio 3.6.3, is there any solution to this issue ?

[androidloverbe]

Hello,

I can confirm the issue is there on latest stable build 3.6.3 Path.op() not supported also when you try to use a FloatingActionButton there is an exception in the preview here is the stack trace

Hello,

I can also confirm all issues disappear on android studio preview version release candidate so this must be a bug which is fixed in the "soon to be stable" version .

[ymarian]

Thanks I was able to verified it's fixed.
