与其他 Google Play 服务不同，Google Play 服务 APK 中的标准 Google 移动广告 SDK 实现也包含在 Google Play 服务客户端库中。这就使得没有 Google Play 服务 APK 的设备也能支持该 SDK。在运行时，该 SDK 会比较客户端库和 Google Play 服务 APK 的版本，并使用较新的版本。
精简版 SDK 从客户端库中剥离了 Google 移动广告 SDK 实现，仅保留了 Google Play 服务 APK 的接口。精简版 SDK 依赖于 APK 的实现。如果您在 Google Play 商店之外部署应用，则无法保证用户设备上安装了 Google Play 服务 APK。
在安装了最新版 Google Play 服务的设备上，精简版 SDK 的行为与标准版 SDK 的行为完全相同。不过，在 Google Play 服务过时或不存在的设备上，精简版 SDK 可能会引用 Google Play 服务 APK 中不可用或已更改的 API。这会导致系统执行空操作并记录错误，从而可能导致广告无法投放到这些设备。

The Google Mobile Ads Lite SDK is a lightweight version\nof Google Mobile Ads SDK built to reduce that impact. It is a fraction of\nthe size of the regular SDK.\n\nAlongside reduced size, using the Lite SDK decreases the total number of\nmethods referenced in an app. This is especially useful when deploying to older\nversions of Android, where developers can run into the [64K reference\nlimit](//developer.android.com/studio/build/multidex).\n\nHere's how to configure gradle to incorporate the Lite SDK into your app: \n\n dependencies {\n implementation 'com.google.android.gms:play-services-ads-lite:24.3.0'\n }\n\nLimitations of the Lite SDK\n\nThe Lite SDK should only be used in apps distributed through the\nGoogle Play store.\n\nUnlike other [Google Play services](/android/guides/overview), the standard\nGoogle Mobile Ads SDK implementation in the Google Play services APK is also\nincluded in the Google Play services client library. This allows for support on\ndevices without the Google Play services APK. At runtime, the SDK will compare\nthe versions of the client library and the Google Play services APK and use the\nnewer version.\n\nThe Lite SDK strips Google Mobile Ads SDK implementation from the client\nlibrary, leaving only an interface to the Google Play services APK. The Lite\nSDK relies on the implementation of the APK. If you deploy your app outside of\nthe Google Play store, it is not guaranteed that your user's devices will have\nthe Google Play services APK installed.\n\nOn devices with an up-to-date version of Google Play services, the Lite SDK's\nbehavior is identical to that of the standard SDK. However, on devices where\nGoogle Play services is outdated or not present, the Lite SDK may reference\nAPIs that are unavailable or have been changed from those in the Google Play\nservices APK. This will result in a no-op and an error being logged, which may\ncause ads not to serve to those devices.\n\nLite SDK release cadence\n\nStarting with version 24.1.0, the `play-services-ads-lite`\nartifact stops releasing at the same cadence as `play-services-ads`. This\nchange allows for a more gradual and stable rollout of the SDK implementation.\nThe Lite SDK releases approximately every third SDK release.\n\nProjects that depend on both `play-services-ads-lite` version 24.0.0 or lower\nand `play-services-ads` version 24.1.0 or higher encounter a `Duplicate class`\nerror during app compilation. Resolve this error by using only one of the\n`play-services-ads` or `play-services-ads-lite` artifacts."]]
