Google Android 1.0 was released with a pre-BETA snapshot of Apache HttpClient. To coincide with 
the first Android release Apache HttpClient 4.0 APIs had to be frozen prematurely, while many of 
interfaces and internal structures were still not fully worked out. As Apache HttpClient 4.0 was 
maturing the project was expecting Google to incorporate the latest code improvements into their 
code tree. Unfortunately it did not happen. Version of Apache HttpClient shipped with Android has 
effectively become a fork. Eventually Google decided to discontinue further development of their 
fork while refusing to upgrade to the stock version of Apache HttpClient citing compatibility 
concerns as a reason for such decision. As a result those Android developers who would like to 
continue using Apache HttpClient APIs on Android cannot take advantage of newer features, 
performance improvements and bug fixes.

Apache HttpClient 4.3 port for Android was intended to remedy the situation by providing official 
releases compatible with Google Android.

Given that as of Android API 23 Google's fork of HttpClient has been removed this project has been 
discontinued.
