How do I build two android app versiosn with different API endpoints without editing code every time?

I have a staging server and prod server at work. I want to build a staging app version and prod app version by changing a build target choice in Eclipse or similar.

How do people do that? Ive searched and learned that it is not part of Eclipse like it is for XCode.

Solution

I use Gradle & Android studio. You can define Debug & release level constants in the gradle file, which then get turned into java source files, which are then compiled are required. Very nifty.

 buildTypes {
        debug {
            buildConfig "public final static String URL = "http://www.test.com;"
        }
        release {
            buildConfig "public final static String URL = "http://www.live.com;"
        }
    }

probably not exactly what you were hoping for but maybe this can help convince you or your lead or your boss,etc to switch :)
