Android ActivityResult API依赖项冲突

我正在使用文档中推荐的ActivityResult API的此依赖项：

    implementation "androidx.activity:activity-ktx:1.2.0-alpha02"
implementation "androidx.fragment:fragment:1.3.0-alpha02"

但它给了我以下错误：

            In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[1.2.0
        -rc02]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

        Dependency failing: androidx.fragment:fragment-ktx:1.2.0-rc02 -> androidx.fragment:fragment@[1.2.0-rc02], but fragment v
        ersion was 1.3.0-alpha02.

        The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
        ifact with the issue.

        For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep
        endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https://
        github.com/google/play-services-plugins and disable by adding "googleServices { disableVersionCheck = false }" to your b
        uild.gradle file.

谁知道如何拯救它
