Android Flavors : Multiple java and src directorie

问题:

Can anyone explain to me how I can use for each of my flavors more then just the main and the flavor specific java/src directories ? My goal is to have directories which are used by more than one flavor but not all of them.

For example I have 3 flavors : A1, A2 and B.

• All favors use main/src (default main src directory)
• A1 uses A1/src (default flavor src directory)
• A2 uses A2/src (default flavor src directory)
• B uses B/src (default flavor src directory)
• A1 and A2 use A/src ("special" shared directory)

Is this possible ? If so, what should I put in my build.gradle file ?

And as a bonus question, can I chose in which order gradle goes looking for files in my different directories ?

For example if I have a.png declared in both A/src and A1/src, can I tell gradle to first look for this file in A/src, and only if nothing is found look for it in A1/src ?

As described here

As mentioned above, each sourceSet can define multiple resource folders.

You can define multiple resource folder. For example something like this:

android {
     ...
     sourceSets {
            main {
                //....
                res.srcDirs = ['/src/main/res']

            }
            flavorA1 {
                 res.srcDirs = ['/src/flavor1/res', '/src/commonA/res']
            }
            flavorA2 {
                 res.srcDirs = ['/src/flavor2/res', '/src/commonA/res']
            }     
            //.....other flavors   
     }
}

I've found a slightly different format is required for setting java source files

sourceSets {
    favorA1 {
        java {
            srcDirs('src/favorA1/java/src', 'src/commonA/java/src')
        }
    }
    favorA2 {
        java {
            srcDirs('src/favorA2/java/src', 'src/commonA/java/src')
        }
    }
}
