Include Http-4.2.1 with Android App

I wish to include the latest version of Http with my Android App, which is 4.2.1. Now wish to download the library from Apache website and include it in the libs folder and then to the build path of my app.

On including Http - 4.2.1, I got the following output in the logcat

08-28 02:42:40.917: D/dalvikvm(25641): DexOpt: 'Lorg/apache/http/client/ResponseHandler;' has an earlier definition; blocking out

08-28 02:42:42.857: D/dalvikvm(25641): DexOpt: not verifying 'Lorg/apache/http/HttpRequestFactory;': multiple definitions

My question is can I do this? Will this create some conflict with already included version of Http library along with the SDK?

Unfortunately this problem does not have an elegant and clean solution. The only option you have is to move all HttpClient classes to a custom namespace ('org.apache.http' -> 'my.http') using maven shade plugin or using a prepackaged fork of the library available here

EDIT

As of today one can also use the official port of Apache HttpClient 4.3 to Google Android.
