Android Studio 中api>9 之后无法找到 org.apache.http 包的问题

本来在ecplices中运行项目正常，但把项目运行到AS中报错提示



直接引用把： http://developer.android.com/about/versions/marshmallow/android-6.0-changes.html#behavior-apache-http-client
Android 6.0 release removes support for the Apache HTTP client. If your app is using this client and targets Android 2.3 (API level 9) or higher, use the HttpURLConnection class instead. This API is more efficient because it reduces
network use through transparent compression and response caching, and minimizes power consumption. To continue using the Apache HTTP APIs, you must first declare the following compile-time dependency in your build.gradle file:

android {

    useLibrary 'org.apache.http.legacy'

}

大概意思就是，Android 6.0不再支持 Apache HTTP client。 请使用 HttpURLConnection 代替。想要继续使用 Apache HTTP client 的，请添加如上代码。
