這么重要的問題竟然事先說明，太過分了。

今天更新了 Android 6.0 的 SDK 后發(fā)現(xiàn)項目一片紅，嚇尿了。

直接引用把：http://developer./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 theHttpURLConnection 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。 請使用HttpURLConnection 代替。想要繼續(xù)使用 Apache HTTP client 的，請?zhí)砑尤缟洗a。
