Android studio 错误：“Android 资源链接失败。 错误：链接引用失败”与谷歌服务 API

Question

您好，我正在尝试将此 google play 服务：com.google.android.gms:play-services-vision:18.0.0 添加到我的应用程序中，但它给了我这个错误：

Android resource linking failed
Output:  /home/user/java/Project/android-storage-permissions-master/app/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:460: error: resource android:attr/fontVariationSettings not found.

这些是我的 build.gradle(Module.App) 依赖项：

dependencies {
    implementation "com.android.support:appcompat-v7:$rootProject.ext.supportLibraryVersion"
    implementation "com.android.support.constraint:constraint-layout:$rootProject.ext.constraintLayoutVersion"
    implementation "com.android.support:design:$rootProject.ext.supportLibraryVersion"
    implementation "com.android.support:recyclerview-v7:$rootProject.ext.supportLibraryVersion"
    implementation "com.android.support:support-core-utils:$rootProject.ext.supportLibraryVersion"
    implementation "com.google.android.gms:play-services-vision:18.0.0"
    implementation "pub.devrel:easypermissions:$rootProject.ext.easypermissionsVersion"

    androidTestImplementation("com.android.support.test.espresso:espresso-core:$rootProject.ext.espressoVersion", {
        exclude group: "com.android.support", module: "support-annotations"
    })

    // Dependencies for local unit tests
    testImplementation "junit:junit:$rootProject.ext.junitVersion"
    testImplementation "org.mockito:mockito-all:$rootProject.ext.mockitoVersion"
    testImplementation "org.hamcrest:hamcrest-all:$rootProject.ext.hamcrestVersion"
    testImplementation "org.powermock:powermock-module-junit4:$rootProject.ext.powerMockito"
    testImplementation "org.powermock:powermock-api-mockito:$rootProject.ext.powerMockito"
    testImplementation "junit:junit:$rootProject.ext.junitVersion"

}

在顶级 gradle 文件中，我使用的是 supportLibraryVersion = '27.1.1'。 我尝试将编译 sdk 版本更改为 v28，但它给了我其他错误，因为我的代码的许多其他部分是为 v27 编写的。 现在我使用 com.google.android.gms:play-services-vision:17.0.2 解决了它。 我想知道是否有其他方法可以解决此错误，请继续使用更新版本的 API。

Answer 1

这是因为该库中使用的属性仅在 API 28 中添加。获取 fontVariationSettings 和 ttcIndex 的唯一方法是将您的编译 SDK 版本升级到 28。另一个选择是降级该库的版本。
