当我在 Android P 设备中运行我的应用时，我收到一些错误：

我应该如何在 Android P 中使用库org.apache.http.legacy？

Answer 1

我看了Android P behavior changes，收到了一些消息：

Apache HTTP客户端弃用   在Android 6.0中，我们删除了对Apache HTTP客户端的支持。   从Android P开始，该库将从中删除   bootclasspath，默认情况下不适用于应用程序。

要继续使用Apache HTTP客户端，   针对Android P及更高版本的应用必须将以下内容添加到其AndroidManifest.xml中：

＆lt; uses-library android：name =“org.apache.http.legacy”android：required =“false”/＆gt;

注意：最低SDK为23或更低的应用程序需要android：required =“false”属性，因为在API级别低于24的设备上，org.apache.http.legacy库不可用。（在这些设备上，Apache HTTP类在bootclasspath上可用。）
