  |     build.gradle
  +- module2/
  |     build.gradle
  +- build.gradle
  +- gradle.properties

global setting for all submodules in gradle.properties

# used for manifest
# todo increment for every release
appVersionCode=19
appVersionName=0.5.2.160726

# android tools settings
appCompileSdkVersion=23
appBuildToolsVersion=23.0.2

usage in a submodule

apply plugin: 'com.android.application'
android {
    // appXXX are defined in gradle.properties
    compileSdkVersion = Integer.valueOf(appCompileSdkVersion)
    buildToolsVersion = appBuildToolsVersion

    defaultConfig {
        // appXXX are defined in gradle.properties
        versionCode = Long.valueOf(appVersionCode)
        versionName = appVersionName
    }
}

dependencies {
    ...
}

Note: If you want to publish your app in the F-Droid app store you have to use magic numbers in the gradle file because else f-droid robot cannot read current versionnumner to detect/verify version changes.
