Question

I use eclipse sometimes to build my android project(Using ADT 19). If i have modified only 1 files then the build happens very quickly from Eclipse (Using Ctr+B). But if i use the ant script (I use “ant debug”) command to build it takes longer. I believe this is because, it is building all the files again.

Basically ant build takes the same time as that of a clean build. Is there some way to speed up the ant build ?

Here is the output of ant script…

Fixed it myself. My IDE was set to clean the project and build it every time. It had ant clean debug. Removed “clean” and it works…
