我正在重构一个应用程序以使用 androidx。我一直在努力摆脱所有不支持它的库。我以为我已经删除了所有使用支持库的库,但看起来仍然有一些东西正在导入它。我现在得到错误:

我有非常相似的问题,在我的情况下,解决方案是在gradle.properties这两行中添加:

android.useAndroidX=true
android.enableJetifier=true

我希望它会有所帮助。

您可以使用./gradlew tasks --all来找出您有哪些任务。其中会有类似的东西yourproject:dependencies,你可以运行它来获得这样的依赖树:

./gradlew yourproject:dependencies

我在添加时遇到了同样的问题,

dataBinding {
    enabled = true
}

在 app.gradle 模块中。我的gradle依赖是:

implementation 'androidx.appcompat:appcompat:1.0.0-alpha3'
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
implementation 'com.google.android.material:material:1.0.0-alpha3'

当我改为,

implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'

我可以在运行项目时摆脱错误。

只是对 AndroidX 库的依赖。

示例:app/build.gradle:

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

至:

implementation 'androidx.appcompat:appcompat:1.0.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'

比再次重建,显示许多错误。只需注释掉这些旧库。重新导入 android x 库包。下面的例子: 在此处输入图像描述

在此处输入图像描述

在此处输入图像描述

在此处输入图像描述

Marge AndroidX:https ://developer.android.com/jetpack/androidx/migrate

我希望能解决你的问题。

我认为这个问题是由于相互依赖的冲突造成的。就我而言,当我删除 androidx 依赖项时,问题就消失了。

从:

dependencies { implementation "androidx.work:work-runtime:2.1.0" }

至: dependencies { implementation "android.arch.work:work-runtime:1.0.1" }

如果您过于依赖 androidx,这可能是不可能的。
