此外，我的Android Studio已下载了以下组件：
我是java / android的新手，所以不知道如何处理。
有人可以帮忙吗？
答案 0 :(得分：1)
您似乎已在使用AndroidX组件而未添加其依赖项。禁用AndroidX支持并使用较早的Android支持组件从XML文件中删除AndroidX组件，或者将以下依赖项添加到您现有的应用级build.gradle文件中：
dependencies {
//...
implementation "androidx.appcompat:appcompat:1.0.0"
implementation "androidx.exifinterface:exifinterface:1.0.0"
implementation "androidx.legacy:legacy-support-core-ui:1.0.0"
implementation "androidx.legacy:legacy-support-core-utils:1.0.0"
}
如果使用AndroidX，请重新检查gradle.properties文件中是否包含这两行：
android.useAndroidX=true
android.enableJetifier=true
将这两个gradle插件标志设置为true意味着Android Plugin将使用适当的AndroidX库而不是支持Library并重写其二进制文件。要了解更多如何将整个项目迁移到AndroidX的信息，请点击以下链接： https://developer.android.com/jetpack/androidx/migrate
