Android studio play-services-ads:12.0.1 与 appcompat-v7:27.1.0 冲突

Question

我正在使用 google ADS sdk 构建一个应用程序，它工作正常，直到今天我收到更新 Android studio 的通知，同时我还提示我更新 Gradle 到 4.4 和所有支持库版本到 27.1.0.

implementation 'com.android.support:appcompat-v7:27.1.0'
implementation 'com.google.android.gms:play-services-ads:12.0.1'

然后我收到 Gradle 错误，指出 Android 依赖项 'com.android.support:support-v4' 具有不同的编译版本 (26.1.0) 和运行时 (27.1.0) 类路径。您应该通过 DependencyResolution

手动设置相同的版本

我搜索了我的代码，没有一个词可以匹配“26.1.0”。我也尝试删除所有 build/gradle 缓存，但仍然无法解决这个问题。所以我使用 gradlew.bat -q dependencies 发现 ADS 库似乎有错误的依赖关系。

这两行很可疑：

+--- com.android.support:support-v4:26.1.0
+--- com.android.support:support-media-compat:26.1.0

与其他依赖项设置相比

有人知道如何摆脱这个吗？ ADS 12.0.1 目前已经是最新版本。

Answer 1

在您的应用级别 build.gradle：

android {
    configurations.all {
        resolutionStrategy.force 'com.android.support:support-v4:27.1.1'
    }
}

这将告诉您的 gradle 配置强制选择并应用 support-v4:27.1.1 它导入的任何地方！

希望对您有所帮助！

Answer 2

我可以通过在我的依赖项中添加这个来解决这个问题

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

或

在您的应用中添加此代码gradle

android {
    configurations.all {
        resolutionStrategy.force 'com.android.support:support-v4:28.0.0'
    }
}
