I've been struggling all day with this issue too. Finally I managed to compile and run the project successfully.

我也一直在为这个问题苦苦挣扎一整天。最后我成功地编译并运行了该项目。

First of all, get rid of this:

首先，摆脱这个：

implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support:design:28.0.0-alpha1'
implementation 'com.android.support:support-v4:28.0.0-alpha1'

Add the following in your gradle.properties file:

在 gradle.properties 文件中添加以下内容：

android.useAndroidX = true
android.enableJetifier = false

And finally, sync the project and then compile.

最后，同步项目然后编译。

If it doesn't work, clean the project and then rebuild.

如果它不起作用，请清理项目，然后重建。

PS: I can't get targetSdkVersion 'p' to work. My build.gradle file end up as follows:

PS：我无法让 targetSdkVersion 'p' 工作。我的 build.gradle 文件最终如下：

apply plugin: 'com.android.application'

android {

        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.google.android.material:material:1.0.0-alpha1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'

    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

}

Hope it works for you too.

I started getting this error after upgrading the ButterKnife to the version 8.8.1.

将 ButterKnife 升级到 8.8.1 版后，我开始收到此错误。

So, I run the command gradle -q dependenciesto generate a dependency report, after that you should see where D8 is coming from. In my case from the "ButterKnife" library:

因此，我运行该命令gradle -q dependencies以生成依赖关系报告，之后您应该会看到 D8 的来源。在我的例子中来自“ButterKnife”库：

+--- com.jakewharton:butterknife:8.8.1
|    |    \--- com.android.support:support-compat:d8

Also you can see your android dependencies by going to your Android Studio Gradle view (In Android Studio tool bar navigate to "View/Tool Windows/Gradle"), and selecting the target "androidDependencies" under "My-Project-Name/Tasks/android" (Double click to run or Right click and run).

您还可以通过转到 Android Studio Gradle 视图（在 Android Studio 工具栏中导航到“View/Tool Windows/Gradle”），然后在“My-Project-Name/Tasks/”下选择目标“androidDependencies”来查看您的 android 依赖项android”（双击运行或右键单击运行）。

To solve this problem I added this piece of code exclude module: 'support-compat'to my "app/build.gradle" as below:

为了解决这个问题，我将这段代码添加exclude module: 'support-compat'到我的“app/build.gradle”中，如下所示：

implementation ('com.jakewharton:butterknife:8.8.1') { 
     exclude module: 'support-compat' 
} 
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'

Hope it works for someone else :] Cheers!

Android Studio v3.2+ resolves this issue. It also adds a "Migrate to AndroidX" item under the Refactor menu. No work-around or rollback required.

Android Studio v3.2+ 解决了这个问题。它还在 Refactor 菜单下添加了“Migrate to AndroidX”项。无需解决方法或回滚。

Update Android Studio from the beta channel to use 3.2+ or wait until a stable version is released.

从 beta 通道更新 Android Studio 以使用 3.2+ 或等待稳定版本发布。

EDIT: Android Studio v3.2 is now in the stable channel. It is important you no longer use the support libraries and migrate to AndroidX libraries because support for the old support libraries has ended.

编辑：Android Studio v3.2 现在处于稳定通道。重要的是您不再使用支持库并迁移到 AndroidX 库，因为对旧支持库的支持已经结束。

回答by Victor Rendina

If you are including a library that has a transitive dependency on the Android support library you also have to use the jetifierfeature that is part of the Android Gradle plugin version 3.2.0-alpha14 or higher. You can determine if you have a library that depends on the support library by running your Gradle dependenciestask.

如果您包含的库对 Android 支持库具有传递依赖关系，您还必须使用jetifierAndroid Gradle 插件版本 3.2.0-alpha14 或更高版本中的功能。您可以通过运行 Gradledependencies任务来确定您是否有依赖于支持库的库。

From the Android Developer's blog post (https://android-developers.googleblog.com/2018/05/hello-world-androidx.html):

来自 Android 开发者的博文（https://android-developers.googleblog.com/2018/05/hello-world-androidx.html）：

If you depend on a library that references the older Support Library, Android Studio will update that library to reference androidx instead via dependency translation. Dependency translation is automatically applied by the Android Gradle Plugin 3.2.0-alpha14, which rewrites bytecode and resources of JAR and AAR dependencies (and transitive dependencies) to reference the new androidx-packaged classes and artifacts. We will also provide a standalone translation tool as a JAR.

如果您依赖引用旧支持库的库，Android Studio 将更新该库以通过依赖关系转换来引用 androidx。Android Gradle Plugin 3.2.0-alpha14 会自动应用依赖关系转换，它会重写 JAR 和 AAR 依赖项（以及传递依赖项）的字节码和资源以引用新的 androidx 打包类和工件。我们还将提供一个独立的翻译工具作为 JAR。

In your gradle.propertiesfile make sure that you have:

在您的gradle.properties文件中，请确保您有：

android.enableJetifier=true android.useAndroidX=true

I wasted 2 days looking for a solution. Anyone who's still looking for a solution can follow the steps below:

我浪费了 2 天寻找解决方案。任何仍在寻找解决方案的人都可以按照以下步骤操作：

Update your Android Studio to the latest version.

Update your compileSdkVersion and targetSdkVersion to 28.

android {

    compileSdkVersion 28

    defaultConfig {
        applicationId "com.your.appid"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 50
        versionName "1.50"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
        setProperty("archivesBaseName", "your-app-$versionName")
        resConfigs "en"
     }
}

Go to your project structure and change your gradle version to 4.10.

Add this dependency first:

implementation 'com.google.android.material:material:1.0.0'

Now remove all the support library dependencies:

implementation "com.android.support:design:$SUPPORT_LIBRARY_VERSION"
implementation "com.android.support:support-v4:$SUPPORT_LIBRARY_VERSION"
implementation "com.android.support:appcompat-v7:$SUPPORT_LIBRARY_VERSION"
implementation "com.android.support:recyclerview-v7:$SUPPORT_LIBRARY_VERSION"
implementation "com.android.support:cardview-v7:$SUPPORT_LIBRARY_VERSION"
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:multidex:1.0.3'
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
androidTestImplementation('com.android.support.test.espresso:espresso- 
   core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
exclude group: 'com.google.code.findbugs', module: 'jsr305'
})

Now paste the following into your gradle.propertiesfile:

android.useAndroidX = true
android.enableJetifier = true

In your project level build.gradlefile:

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.0'
    classpath 'com.google.gms:google-services:4.1.0'
};

将您的 Android Studio 更新到最新版本。

将 compileSdkVersion 和 targetSdkVersion 更新为 28。

android {

    compileSdkVersion 28

    defaultConfig {
        applicationId "com.your.appid"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode 50
        versionName "1.50"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
        setProperty("archivesBaseName", "your-app-$versionName")
        resConfigs "en"
     }
}

转到您的项目结构并将您的 gradle 版本更改为4.10。

首先添加此依赖项：

implementation 'com.google.android.material:material:1.0.0'

现在删除所有支持库依赖项：

implementation "com.android.support:design:$SUPPORT_LIBRARY_VERSION"
implementation "com.android.support:support-v4:$SUPPORT_LIBRARY_VERSION"
implementation "com.android.support:appcompat-v7:$SUPPORT_LIBRARY_VERSION"
implementation "com.android.support:recyclerview-v7:$SUPPORT_LIBRARY_VERSION"
implementation "com.android.support:cardview-v7:$SUPPORT_LIBRARY_VERSION"
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:multidex:1.0.3'
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
androidTestImplementation('com.android.support.test.espresso:espresso- 
   core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
exclude group: 'com.google.code.findbugs', module: 'jsr305'
})

现在将以下内容粘贴到您的gradle.properties文件中：
```
android.useAndroidX = true
android.enableJetifier = true
```

在您的项目级build.gradle文件中：

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.0'
    classpath 'com.google.gms:google-services:4.1.0'
};

For those who are using Butterknifeadd below lines in your project level build.gradle file:

对于那些使用Butterknife 的人，在你的项目级 build.gradle 文件中添加以下几行：

allprojects {
    repositories {
    google()
    jcenter()
    maven { url "https://jitpack.io" }
    maven { url "https://dl.bintray.com/drummer-aidan/maven/" }
    maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
  }
}

And in your module build.gradlefile add below dependencies:

并在您的模块build.gradle文件中添加以下依赖项：

 implementation "com.jakewharton:butterknife:9.0.0-SNAPSHOT"
 annotationProcessor "com.jakewharton:butterknife-compiler:9.0.0-SNAPSHOT"

Now Goto Build > Rebuild Projectthen you might be getting a lot of errors.

现在转到Build > Rebuild Project那么你可能会遇到很多错误。

Now refer thislink.

It has the list of all the old(android.support) vs new(androidx.*) dependencies.

Replace all your old importswith the newones
(Use replaceAll feature of android studio [ctrl + shift + R] which will save you some time).

现在参考这个链接。

它包含所有旧(android.support) 和新(androidx.*) 依赖项的列表。

替换所有的旧进口与新的人
（机器人工作室[Ctrl + Shift + R]这将节省您的时间使用的replaceAll功能）。

Finally After refactoring all the old libraries with the new ones:
Rebuild the project again and hopefully it should work.

最后在用新库重构所有旧库之后：
再次重建项目，希望它可以工作。

Note: You can also use Refactor > Migrate to androidxin android studio but it didn't work for me.

注意：您也可以在 android studio 中使用Refactor > Migrate to androidx但它对我不起作用。
