HTTP Patch request from Android

Question

I\'m trying to do an HTTP Patch request from an Android application and haven\'t been able to figure it out. It looks like PATCH isn\'t supported by HTTPUrlConnection. HttpPat

If the Patch method is absolutely necessary you will have to import the Apache HttpClient as a jar dependency. This will increase the size of your app somewhat but it should not be a huge problem.

As a workaround you could try to just include this java code in your app:

/**

 * The HTTP PATCH method is defined in RF5789: 
 The PATCH

 * method in the way the server processes the enclosed entity to modify the
 * resource identified by the Request-URI. In a PUT request, the enclosed entity
 * origin server, and the client is requesting that the stored version be
 * replaced. With PATCH, however, the enclosed entity contains a set of
 * instructions describing how a resource currently residing on the origin
 * server should be modified to produce a new version.
