Use xdelta to create a differential File

Xdelta is a good tool for making binary file difference. Sometimes, our APK installation package is very large. In release, if a large package is uploaded every time, the efficiency is definitely not good. I recommend a tool here, to generate binary differential files, that is, xdelta.

In ubuntu:

1. Install

$ Sudo apt-Get install xdelta

2. Create a differential File

$ Xdelta delta (sorce file) (destination file) test. xdelta

3. Merge differential files

$ Xdelta patch test. xdelta (source file) (destination file)
