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

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'

然后我得到了Gradle错误,说Android依赖项'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,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依赖关系来发现它似乎ADS库有错误的依赖.

这两行非常可疑:

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

与其他依赖项设置相比

有没有人如何摆脱这个？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!

希望这可以帮助!
