| To begin with the process takes advantage of Gradle environment variables. Four variables are used, versionMajor, versionMinor, versionHotfix and buildNum. The first three are currently manually set and represent the application version number. 2.4.1 for example. The buildNum variable is retrieved from a Jenkins environment variable or hardcoded to 9999 for desktop builds. The Jenkins build number is always unique for the build being created. The following code block is inserted in the build.gradle file for the Application being built. | To begin with the process takes advantage of Gradle environment variables.

| + | The code above creates two Gradle environment variables "versionCode" and "versionName". The versionCode variable is used to create a build number which is substituted into the AndroidManifest.xml for each build. This is the number that must role forward for every APK created. It take the major, minor and build number to create a unique build number. The key is the use of the Jenkins build number which is always moving forward for any given release build. The versionName is just the normal human readable version name such as 2.4.1. It is also used in the AndroidManifest.xml file and is grabbed by the About page in each app. | ||
