我得到以下错误：

    Information:Gradle tasks [:app:assembleDebug]
    Warning:Dependency org.apache.httpcomponents:httpclient:4.0.1 is ignored for debug as it may be conflicting with the internal version provided by Android.
             In case of problem, please repackage it with jarjar to change the class packages

我知道libs2中的文件会导致错误，因为我会根据此人的建议逐个添加它们，看看哪些会导致问题。

我正在遵循一个教程，该教程需要所有这些.jar文件，所以我不明白为什么我会收到这些错误，因为它们是必要的。
