Android custom build using Ant

Question

These 4 files (build.xml, local.properties, projects.properties, proguard.cfg) are auto-generated when running:

android update project --name TestApp --t

Answer 1

The build.xml as generated by the android tool (at least when using Android SDK r20) contains this piece of code:

So what I do to create additional targets or customize existing targets is to create a custom_rules.xml file with these new targets. Note that in my tests the targets needed to be nested in a tag, so simply copy the first two lines of your generated build.xml to custom_rules.xml, and don't forget about the closing tag in the end. As custom_rules.xml will not be overwritten by android update your changes will be persistent and can be checked into your SCM tool of choice.
