无法解决:com.google.android.material:material:1.0.0-alpha1

Question

所以我按照官方文档将Material Components库添加到我的项目https://github.com/material-components/material-components-android/blob/master/docs/getting-started.md

但它引发了以下错误"无法解决:com.google.android.material:material:1.0.0-alpha1"

我已经尝试安装Android Studio建议无效的存储库和同步项目.

我的项目配置

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.2'


    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    classpath 'com.google.gms:google-services:3.2.1'
}
}

allprojects {
repositories {
    google()
    jcenter()
    maven {
        url "https://maven.google.com"
    }
}


task clean(type: Delete) {
delete rootProject.buildDir
}

和应用程序配置

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
defaultConfig {
    applicationId "mlluell.eftremp"
    minSdkVersion 21
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

}

Answer 1

代替：

implementation 'com.google.android.material:material:1.1.0'

使用：

   implementation group: 'com.google.android.material', name: 'material', version: '1.1.0-alpha05'

而且有效。

Answer 2

我以为我已经开始分享为我解决的问题.

我和你的初始设置大致相同.为了让它工作,我不得不改变以下内容:

• compileSdkVersion to 'android-P'
• 支持图书馆 '28.0.0-alpha1'
• 包含api 'com.android.support:design:28.0.0-alpha1'在依赖项块中.
• SDK平台更新 - Android P预览版(最新)
• targetSdkVersion 'P'

然后我做了仪式'无效缓存/重新启动'并重建项目以获得良好的衡量标准.

Answer 3

对于安卓用户。
您可以按如下方式实现...

AndroidX
实现 'com.google.android.material:material:1.0.0-alpha3'

旧构建工件用户可以使用以下实现
实现 'com.android.support:design:[Enter Design library version here]'

*使用没有方括号的那个版本。
您可以通过此链接找到设计库版本：https : //mvnrepository.com/artifact/com.android.support/design/28.0.0-alpha1

Answer 4

implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'com.google.android.material:material:1.0.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
androidTestImplementation 'androidx.test:runner:1.2.0'`
