android - 添加 Material 依赖项时合并 list 错误

Question

添加时

implementation 'com.google.android.material:material:1.1.0-alpha10'

在 gradle 文件和构建中错误是:

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
    is also present at [androidx.core:core:1.1.0-rc03] AndroidManifest.xml:24:18-86 value=(androidx.core.app.CoreComponentFactory).
    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:10:5-36:19 to override.

当在 list 文件中添加 tools:replace="android:appComponentFactory" 时，我遇到了另一个错误 新的错误消息是: list 合并失败并出现多个错误，请参阅日志

我的gedle文件:

android {
compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {
    applicationId "com.saat.ali.hozorghiab"
    minSdkVersion 21
    targetSdkVersion 28

检查official doc Material 组件库:

If your app currently depends on the original Design Support Library, you can make use of the Refactor to AndroidX… option provided by Android Studio. Doing so will update your app's dependencies and code to use the newly packaged androidx and com.google.android.material libraries.

If you don't want to switch over to the new androidx and com.google.android.material packages yet, you can use Material Components via the com.android.support:design:28.0.0 dependency.

Note: You should not use the com.android.support and com.google.android.material dependencies in your app at the same time.

您必须使用 AndroidX 库。
