Warning:Dependency org.apache.httpcomponents:httpclient:4.0.1 is ignored

Question

When I try adding any of the the .jar files that are in my libs2 folder to my libs folder

I get the following error:

    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

    :app:preBuild UP-TO-DATE
   .....
    :app:compileDebugNdk UP-TO-DATE
    :app:compileDebugSources
    :app:transformClassesWithDexForDebug

I know for a fact that the files in libs2 cause the error since I would add them one by one and see which ones would cause a problem or not, based on this persons suggestion .

I am following a tutorial which requires all of those .jar files, so I do not understand why I am getting those errors since they are necessary.

Answer 1

with Gradle no need to downgrade or to find another jar - since one can filter per group/module:

compile ('com.google.http-client:google-http-client-jackson2:1.21.0') {
    exclude group: 'org.apache.httpcomponents', module: 'httpclient'
}

在5.0及以上版本（api 23+）中，http客户端已被删除，甚至不存在降级您的maxsdk或使用url连接的情况，您应该找到与api23 +兼容的最新jar文件。
