Question

我正在使用谷歌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工作室的通知，同时我还提示将Gradle更新到4.4并将所有支持库版本更新到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，说 Android依赖'com.android.support:support-v4'对于编译（26.1.0）和运行时（27.1.0）类路径有不同的版本。您应该通过DependencyResolution

手动设置相同的版本

我搜索了我的代码，并没有一个词可以匹配“26.1.0”。我也试图删除所有的构建/ gradle缓存，但仍然无法摆脱这个问题。所以我使用 gradlew.bat -q依赖来发现ADS库似乎有错误的依赖。

这两行非常可疑：

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

与其他依赖设置相比

有人如何摆脱这个？ ADS 12.0.1目前已经是最新版本。

Answer 1

在您的应用级build.gradle：

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

这将告诉您的gradle配置在其导入的任何地方强行挑选并应用support-v4:27.1.1！

希望这有帮助！

Answer 2

我可以通过将其添加到我的行为中来解决此问题

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

OR

将此代码添加到您的应用程序gradle中

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

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