我想创建一个Unity应用程序，显示Admob的横幅广告。所以，在this之后，我添加了Admob Unity插件。但是，构建时会发生以下错误。
这是控制台：
CommandInvokationFailure: Gradle build failed.
/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/bin/java -classpath "/Applications/Unity/PlaybackEngines/AndroidPlayer/Tools/gradle/lib/gradle-launcher-4.0.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx2048m" "assembleRelease"
stderr[

上面的日志说add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:23:9-25:38 to override.，所以我添加以下代码。
资产/插件/安卓/ AndroidManifest.xml中：
<manifest>
<application>
...
<meta-data
tools:replace="android:value"
android:name="android.support.VERSION"
android:value="26.0.2" />
</application>
</manifest>
然后上面的错误已经解决。但是，会发生以下错误。
这是控制台：
CommandInvokationFailure: Gradle build failed.
/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/bin/java -classpath "/Applications/Unity/PlaybackEngines/AndroidPlayer/Tools/gradle/lib/gradle-launcher-4.2.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx2048m" "assembleRelease"

请告诉我如何解决此错误。提前致谢。
注意：Unity版本：版本2018.2.6f1个人
检查Android studio中的外部库，并添加此代码的build.gradle设置
implementation fileTree(include: ['*.jar'], dir: 'libs', exclude: ['classes.jar'])
compileOnly files('libs/classes.jar')
（classes.jar是文件名包括com / google / android / gms / common / api / zzd）
最后我自己解决了这个错误。就我而言，以下解决方案有效。
这是build.gradle（app level）
// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

jcenter()
google()

classpath 'com.android.tools.build:gradle:3.0.1'

从团结论坛找到适合我的解决方案。将构建系统从Gradle更改为Internal
从sRn开始“嘿，我希望这是Unity的错误，并且会在某些时候得到解决，因为我在将项目更新到2018.2.1f1 Unity版本后开始出现此错误。要解决此问题，您可以尝试启用Multidex，但之后我这样做了，我又遇到了另一个问题，所以我不再烦恼了，回到了2018.1.x - 这对我来说很好。你也可以把Build System从Gradle改为Internal（在File-> Build Settings中 - > Build System），对我来说也很有用，但我想和Gradle保持更多的控制权，所以回到2018.1更有意义。“
我通过以下方式解决了错误：服务 - >广告 - >高级 - >取消选中：启用内置广告扩展程序。
