The type org.apache.http.HttpResponse cannot be resolved. It is indirectly referenced from required

在Android 6.0（API 23）中，Google已经移除了移除了Apache HttpClient相关的类、HttpResponse类。缺失jar包使用HttpResponse等会报错：

The type org.apache.http.HttpResponse cannot be resolved. It is indirectly referenced from required

推荐使用HttpUrlConnection，如果要继续使用需要Apache HttpClient，需要在eclipse下libs里添加org.apache.http.legacy.jar。添加方法如下：

1>、Eclipse中 在错误原因上点击ctrl+1，选择Configure build path，或者Project->Properties->Java Build Path->Libraries->Add Ecternal JARS->你的SDK目录的

\platforms\android-23\optional\org.apache.http.legacy.jar->ok

2>、android studio里在相应的module下的build.gradle中加入：

android {

useLibrary 'org.apache.http.legacy'

}
