推荐答案

更新:这不再是错误或解决方法，如果您的应用面向 API 级别 28 (Android 9.0) 或以上并使用适用于 Android 16.0.0 或以下版本的 Google Maps SDK(或者如果您的应用程序使用 Apache HTTP Legacy 库).它现在包含在官方文档中.公开问题已按照预期行为关闭.

Update: This is no longer a bug or a workaround, it is required if your app targets API Level 28 (Android 9.0) or above and uses the Google Maps SDK for Android 16.0.0 or below (or if your app uses the Apache HTTP Legacy library). It is now included in the official docs. The public issue has been closed as intended behavior.

这是 Google Play 服务方面的错误，在修复之前，您应该能够通过将其添加到 <application> 标签内的 AndroidManifest.xml 来解决:

This is a bug on the Google Play Services side, until it's fixed, you should be able to workaround by adding this to your AndroidManifest.xml inside the <application> tag:

<uses-library android:name="org.apache.http.legacy" android:required="false" />
