Here is my v31/values-v31

While I'm trying to build this project . I'm frequently getting this error(

ERROR:C:\Users\Dell.gradle\caches\transforms-2\files-2.1\66e9dd10963e7a2704a4a2116f19e6fb\material-1.5.0-alpha03\res\values-v31\values-v31.xml:3:5-94: AAPT: error: resource android:color/system_neutral1_1000 not found.)

Solutions I tried Rebuild project, clean project, Invalidate cache and restart, enter code hereand also delete and newly create that emulator but nothing worked for me

Answer 1

As described in the release notes:

The version 1.5.0-alpha03 introduces the new Material 3 themes and

Make sure to update your app's compileSdkVersion to 31 when using this version of the library.

Answer 2

Short answer:

To fix the compilation error, make sure to update your app’s compileSdkVersion to 31 when using fresh versions of the Material Components library.

Or you can downgrade the Material Components library to 1.4.0 or 1.5.0-alpha02.

Explanations:

Starting from version 1.5.0-alpha03, Material Components library requires compile SDK version 31 (was raised at commit 40509dc).
See release notes on GitHub.

It is required because of the new Material 3 themes with dynamic colors support.
Starting from Android S (API 31), the framework provides the ability to support dynamic colors in your UI based on the user’s wallpaper or color choice on the device.
