We publish our APK files to our local Nexus repository using gradle. This is what I've come up with. This example demonstrated using a "googlePlay" build flavor.

// make sure the release builds are made before we try to upload them.    
uploadArchives.dependsOn(getTasksByName("assembleRelease", true))

// create an archive class that known how to handle apk files.
// apk files are just renamed jars.
class Apk extends Jar {
    def String getExtension() {
        return 'apk'
    }
}

// create a task that uses our apk task class.
task googlePlayApk(type: Apk) {
    classifier = 'googlePlay'
    from file("${project.buildDir}/outputs/apk/myApp-googlePlay-release.apk")
}

// add the item to the artifacts
artifacts {
    archives googlePlay
}
