升级Yandex广告SDK后遇Kotlin版本不兼容问题，求解决方案

我在Android应用的build.gradle中，将Yandex广告SDK依赖从：

implementation 'com.yandex.android:mobileads:5.10.0'
implementation 'com.yandex.ads.mediation:mobileads-admob:22.1.0.0'

升级为：

implementation 'com.yandex.android:mobileads:6.2.0'
implementation 'com.yandex.ads.mediation:mobileads-google:22.4.0.0'

后，出现了如下编译错误：

请问这是否意味着我需要升级Java版本？当前我的项目配置如下：

• 项目build.gradle中的编译选项：

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

• 实际构建使用的Java路径为C:\Program Files\Android\Android Studio\jbr\bin，版本信息：

javac --version
javac 17.0.6

这个错误和Java版本无关，是Kotlin版本不兼容导致的：新升级的Yandex SDK依赖了Kotlin 1.8编译的库，但你的项目当前使用的Kotlin插件版本是1.6，两者元数据版本不匹配，所以编译报错。

解决步骤如下：

1. 打开项目根目录下的Project级build.gradle文件，找到Kotlin插件的版本配置，示例如下：

plugins {
    id 'com.android.application' version 'x.x.x' apply false
    id 'org.jetbrains.kotlin.android' version '1.6.x' apply false
}

2. 将Kotlin插件版本升级到1.8.22或更高兼容版本（和报错中出现的Kotlin stdlib版本一致即可），修改后示例：

plugins {
    id 'com.android.application' version 'x.x.x' apply false
    id 'org.jetbrains.kotlin.android' version '1.8.22' apply false
}

3. 点击Android Studio右上角的"Sync Project with Gradle Files"按钮同步项目，之后重新编译即可。

另外，你的Java版本17符合要求，无需调整；项目中配置的sourceCompatibility和targetCompatibility为1.8也没问题，Android Studio会自动处理Java版本的兼容编译。
