AndroidAutoVersion

This is a Gradle plugin, for Android developers, that automates app versioning.

AndroidAutoVersion tasks
------------------------
bumpMajor - Increases major version by 1, zeroes out minor and patch version
bumpMinor - Increases minor version by 1 and zeroes out patch version
bumpPatch - Increases patch version by 1
versionMajor - Executes bumpMajor and commits the changes to git
versionMinor - Executes bumpMinor and commits the changes to git
versionPatch - Executes bumpPatch and commits the changes to git

Features

• Update app version from CLI
• Automatically commit version update to git
• Automatically creates git tag

Requirements

• Android Gradle Plugin 3.0+
• Gradle 4.0+
• Git

Installation

Step 1

Include the following in your top-level build.gradle file:

buildscript {
  repositories {
    maven { url 'https://jitpack.io' }
  }
  dependencies {
    classpath 'com.github.alexfu:androidautoversion:$latest_version'
  }
}

Change $latest_version to the latest release version found here.

Step 2

Include the following in your app-level build.gradle file:

apply plugin: 'com.github.alexfu.androidautoversion'

Step 3

Replace versionCode and versionName:

  defaultConfig {
    versionName androidAutoVersion.versionName
    versionCode androidAutoVersion.versionCode
  }

Usage

When building your project for the first time with this plugin, you should notice a new file added to your project: [module name]/version. This is called a version file. You should check this file into version control (i.e. git) since this file will contain the current version information.

If you're adding AndroidAutoVersion to an already existing project you need to populate the version file's major, minor, patch, and buildNumber fields with what was in the versionName and versionCode fields.

For example, a project with the following app/build.gradle file:

  defaultConfig {
    versionName "2.0.5"
    versionCode 9
  }

Should update the version file to look like so:

{"major":2,"minor":0,"patch":5,"buildNumber":9}

Every time you want to make a release, decide if it's a major, minor, or a patch. If you're not sure, check out the rules outlined here to make your decision. Then, once you've decided, run one of the following gradle tasks:

• ./gradlew bumpPatch
• ./gradlew bumpMinor
• ./gradlew bumpMajor

Running one of these will update the version, but it will be up to you to commit any changes to version control.

If you use git (which you should), the plugin also has tasks that will execute the corresponding bump task, commit the version update, and create the necessary version tag.

• ./gradlew versionPatch
• ./gradlew versionMinor
• ./gradlew versionMajor

Tips

Alpha/Beta

If you have alpha/beta versions of your app and want to signify that in your version, i.e. 1.2.3.alpha, then you can use the versionNameSuffix property in your alpha/beta product flavors. For example:

android {
    productFlavors {
        alpha {
            versionNameSuffix ".alpha"
        }

        beta {
            versionNameSuffix ".beta"
        }
    }
}

Automate release workflow

Because this plugin allows you to update your app version from the command line, you can completely automate your entire release workflow with a simple script.

$ ./gradlew clean versionPatch assembleRelease
