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

The problem is in the following line:

implementation 'com.google.android.material:material:1.5.0-alpha03'

I used this and got the same error. Replacing it with the following line fixed the problem:

implementation 'com.google.android.material:material:1.5.0-alpha02')

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.

Answer 3

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 4

I've meet this error, and it's solved. Change or downgrade your dependencies should solve this issue. If you meet this error from this link, I suggest you should change this both, from :

implementation 'androidx.appcompat:appcompat:1.4.0'
implementation 'com.google.android.material:material:1.5.0'

to :

implementation 'androidx.appcompat:appcompat:1.3.0'
implementation 'com.google.android.material:material:1.4.0'

then, run your app again. I think this method works. This usually happen if you create your new project, but you didn't notice this error, when you trying to run your app.

Answer 5

I ran into this error as well, when trying to target API 30 in a Java project. I had tried to downgrade the appcompat dependency only and got these errors. Turns out you need to downgrade the material dependency as well.

To target API 30, you need to downgrade both androidx.appcompat:appcompat and com.google.android.material:material to older versions.

Change the versions from:

implementation 'androidx.appcompat:appcompat:1.4.1'
implementation 'com.google.android.material:material:1.5.0'

To:

implementation 'androidx.appcompat:appcompat:1.3.1'
implementation 'com.google.android.material:material:1.4.0'

Answer 6

Not quite sure if this is the solution (it worked for me) but updating the compileSdk and targerSdk to 31 alongside with updating these libraries solved the error in my case:

implementation 'androidx.core:core-ktx:1.7.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.3'
implementation 'com.google.android.material:material:1.5.0'

Answer 7

Follow these Steps

In build.gradle ( Module )

        apply plugin: 'com.android.application'
        apply plugin: 'com.google.gms.google-services'
        
        
        android {
            compileSdkVersion 30
            buildToolsVersion '30.0.2'
        
            defaultConfig {
                applicationId "your package name"
                minSdkVersion 21
                targetSdkVersion 30
                versionCode 1
                versionName "1.0"
        
                testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
            }
        
            buildTypes {
                release {
                    minifyEnabled false
                    proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
                }
            }
            compileOptions {
                sourceCompatibility JavaVersion.VERSION_1_8
                targetCompatibility JavaVersion.VERSION_1_8
            }
        
        }
        
        dependencies {
        
            implementation fileTree(dir: 'libs', include: ['*.jar'])
            implementation 'androidx.appcompat:appcompat:1.3.0'
            implementation 'com.google.android.material:material:1.4.0'
            implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
            testImplementation 'junit:junit:4.12'
            androidTestImplementation 'androidx.test.ext:junit:1.1.1'
            androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
        }
    
    

In build.gradle (project) enter code here

    // Top-level build file where you can add configuration options common to all sub-projects/modules.
    buildscript {
        repositories {
            google()
            jcenter()
        }
        dependencies {
            classpath "com.android.tools.build:gradle:4.0.1"
