Autoincrement VersionCode with gradle extra proper

Question

I'm building an Android app with gradle. Until now I used the Manifest file to increase the versionCode, but I would like to read the versionCode from an external file and depending if it is the release flavor or the debug flavor increase the versionCode. I tried the extra properties, but you can't save them, which means that next time I build it I'm getting the same versionCode. Any help would be very much appreciated!

project.ext{
    devVersionCode = 13
    releaseVersionCode = 1
}

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}

apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    compile project(':Cropper')
    compile "com.android.support:appcompat-v7:18.0.+"
    compile "com.android.support:support-v4:18.0.+"
    compile fileTree(dir: 'libs', include: '*.jar')
}

def getReleaseVersionCode() {
    def version = project.releaseVersionCode + 1
    project.releaseVersionCode = version
    println sprintf("Returning version %d", version)
    return version
}

def getDevVersionCode() {
    def version = project.devVersionCode + 1
    project.devVersionCode = version
    println sprintf("Returning version %d", version)
    return version
}


def getLastVersioName(versionCode) {
    return "0.0." + versionCode
}

So I mashed all their ideas together and came up with this. This is the drag and drop solution to exactly what the first post asked.

It will automatically update the versionCode and versionName according to release status. Of course you can move the variables around to suite your needs.

def _versionCode=0
def versionPropsFile = file('version.properties')
def Properties versionProps = new Properties()
if(versionPropsFile.exists())
    versionProps.load(new FileInputStream(versionPropsFile))
    def _patch = (versionProps['PATCH'] ?: "0").toInteger() + 1
    def _major = (versionProps['MAJOR'] ?: "0").toInteger()
    def _minor = (versionProps['MINOR'] ?: "0").toInteger()
    List<String> runTasks = gradle.startParameter.getTaskNames();
    def value = 0
    for (String item : runTasks)
        if ( item.contains("assembleRelease")) {
            value = 1;
        }
    _versionCode = (versionProps['VERSION_CODE'] ?: "0").toInteger() + value
    if(_patch==99)
    {
        _patch=0
        _minor=_minor+1
    }
    if(_major==99){
        _major=0
        _major=_major+1
    }

versionProps['MAJOR']=_major.toString()
versionProps['MINOR']=_minor.toString()
versionProps['PATCH']=_patch.toString()
versionProps['VERSION_CODE']=_versionCode.toString()
versionProps.store(versionPropsFile.newWriter(), null)
def _versionName = "${_major}.${_versionCode}.${_minor}.${_patch}"

compileSdkVersion 24
buildToolsVersion "24.0.0"

defaultConfig {
    applicationId "com.yourhost.yourapp"
    minSdkVersion 16
    targetSdkVersion 24
    versionCode _versionCode
    versionName _versionName
}

Recently I was working on a gradle plugin for Android that makes generating versionCode and versionName automatically. there are lots of customization. here you can find more info about it https://github.com/moallemi/gradle-advanced-build-version

Answer 3

Create file version.properties

MAJOR=1
MINOR=3
PATCH=6
VERSION_CODE=1

Change build.gradle :

android {
def _versionCode=0
def _major=0
def _minor=0
def _patch=0

def _applicationId = "com.example.test"

def versionPropsFile = file('version.properties')

if (versionPropsFile.canRead()) {
    def Properties versionProps = new Properties()

    versionProps.load(new FileInputStream(versionPropsFile))

    _patch = versionProps['PATCH'].toInteger() + 1
    _major = versionProps['MAJOR'].toInteger()
    _minor = versionProps['MINOR'].toInteger() 
    _versionCode= versionProps['VERSION_CODE'].toInteger()+1
    if(_patch==99)
    {
        _patch=0
        _minor=_minor+1
    }
    if(_major==99){
        _major=0
        _major=_major+1
    }

    versionProps['MAJOR']=_major.toString()
    versionProps['MINOR']=_minor.toString()
    versionProps['PATCH']=_patch.toString()
    versionProps['VERSION_CODE']=_versionCode.toString()
    versionProps.store(versionPropsFile.newWriter(), null)
}
else {
    throw new GradleException("Could not read version.properties!")
}
def _versionName = "${_major}.${_versionCode}.${_minor}.${_patch}"


compileSdkVersion 23
buildToolsVersion "23.0.3"

defaultConfig {
    applicationId _applicationId
    minSdkVersion 11
    targetSdkVersion 23
    versionCode _versionCode
    versionName _versionName
}

}

Output : 1.1.3.6

Answer 4

Here comes a modernization of my previous answer which can be seen below. This one is running with Gradle 4.4 and Android Studio 3.1.1.

What this script does:

• Creates a version.properties file if none exists (up vote Paul Cantrell's answer below, which is where I got the idea from if you like this answer)
• For each build, debug release or any time you press the run button in Android Studio the VERSION_BUILD number increases.
• Every time you assemble a release your Android versionCode for the play store increases and your patch number increases.
• Bonus: After the build is done copies your apk to projectDir/apk to make it more accessible.

This script will create a version number which looks like v1.3.4 (123) and build an apk file like AppName-v1.3.4.apk.

Major version ⌄       ⌄ Build version
             v1.3.4 (123)
  Minor version ⌃|⌃ Patch version

Major version: Has to be changed manually for bigger changes.

Minor version: Has to be changed manually for slightly less big changes.

Patch version: Increases when running gradle assembleRelease

Build version: Increases every build

Version Number: Same as Patch version, this is for the version code which Play Store needs to have increased for each new apk upload.

Just change the content in the comments labeled 1 - 3 below and the script should do the rest. :)

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.3'

    def versionPropsFile = file('version.properties')
    def value = 0
    Properties versionProps = new Properties()
    if (!versionPropsFile.exists()) {
        versionProps['VERSION_PATCH'] = "0"
        versionProps['VERSION_NUMBER'] = "0"
        versionProps['VERSION_BUILD'] = "-1" // I set it to minus one so the first build is 0 which isn't super important. 
        versionProps.store(versionPropsFile.newWriter(), null)
    }

    def runTasks = gradle.startParameter.taskNames
    if ('assembleRelease' in runTasks) {
        value = 1
    }

    def mVersionName = ""
    def mFileName = ""

    if (versionPropsFile.canRead()) {
        versionProps.load(new FileInputStream(versionPropsFile))

        versionProps['VERSION_PATCH'] = (versionProps['VERSION_PATCH'].toInteger() + value).toString()
        versionProps['VERSION_NUMBER'] = (versionProps['VERSION_NUMBER'].toInteger() + value).toString()
        versionProps['VERSION_BUILD'] = (versionProps['VERSION_BUILD'].toInteger() + 1).toString()

        versionProps.store(versionPropsFile.newWriter(), null)

        // 1: change major and minor version here
        mVersionName = "v1.0.${versionProps['VERSION_PATCH']}"
        // 2: change AppName for your app name
        mFileName = "AppName-${mVersionName}.apk"

        defaultConfig {
            minSdkVersion 21
            targetSdkVersion 27
            applicationId "com.example.appname" // 3: change to your package name
            versionCode versionProps['VERSION_NUMBER'].toInteger()
            versionName "${mVersionName} Build: ${versionProps['VERSION_BUILD']}"
        }

    } else {
        throw new FileNotFoundException("Could not read version.properties!")
    }

    if ('assembleRelease' in runTasks) {
        applicationVariants.all { variant ->
            variant.outputs.all { output ->
                if (output.outputFile != null && output.outputFile.name.endsWith('.apk')) {
                    outputFileName = mFileName
                }
            }
        }
    }

    task copyApkFiles(type: Copy){
        from 'build/outputs/apk/release'
        into '../apk'
        include mFileName
    }

    afterEvaluate {
        assembleRelease.doLast {
            tasks.copyApkFiles.execute()
        }
    }

    signingConfigs {
        ...
    }

    buildTypes {
        ...
    }
}

====================================================

INITIAL ANSWER:

I want the versionName to increase automatically as well. So this is just an addition to the answer by CommonsWare which worked perfectly for me. This is what works for me

defaultConfig {
    versionCode code
    versionName "1.1." + code
    minSdkVersion 14
    targetSdkVersion 18
}

EDIT:

As I am a bit lazy I want my versioning to work as automatically as possible. What I want is to have a Build Version that increases with each build, while the Version Number and Version Name only increases when I make a release build.

This is what I have been using for the past year, the basics are from CommonsWare's answer and my previous answer, plus some more. This results in the following versioning:

Version Name: 1.0.5 (123) --> Major.Minor.Patch (Build), Major and Minor are changed manually.

In build.gradle:

...
android {
    compileSdkVersion 23
    buildToolsVersion '23.0.1'
    def versionPropsFile = file('version.properties')
    if (versionPropsFile.canRead()) {
        def Properties versionProps = new Properties()

        versionProps.load(new FileInputStream(versionPropsFile))

        def value = 0

        def runTasks = gradle.startParameter.taskNames
        if ('assemble' in runTasks || 'assembleRelease' in runTasks || 'aR' in runTasks) {
            value = 1;
        }

        def versionMajor = 1
        def versionMinor = 0
        def versionPatch = versionProps['VERSION_PATCH'].toInteger() + value
        def versionBuild = versionProps['VERSION_BUILD'].toInteger() + 1
        def versionNumber = versionProps['VERSION_NUMBER'].toInteger() + value

        versionProps['VERSION_PATCH'] = versionPatch.toString()
        versionProps['VERSION_BUILD'] = versionBuild.toString()
        versionProps['VERSION_NUMBER'] = versionNumber.toString()

        versionProps.store(versionPropsFile.newWriter(), null)

        defaultConfig {
            versionCode versionNumber
            versionName "${versionMajor}.${versionMinor}.${versionPatch} (${versionBuild}) Release"
            minSdkVersion 14
            targetSdkVersion 23
        }

        applicationVariants.all { variant ->
            variant.outputs.each { output ->
                def fileNaming = "apk/RELEASES"
                variant.outputs.each { output ->
                    def outputFile = output.outputFile
                    if (outputFile != null && outputFile.name.endsWith('.apk')) {
                        output.outputFile = new File(getProject().getRootDir(), "${fileNaming}-${versionMajor}.${versionMinor}.${versionPatch}-${outputFile.name}")
                    }
                }
            }
        }

    } else {
        throw new GradleException("Could not read version.properties!")
    }

    ...
}

...

Patch and versionCode is increased if you assemble your project through the terminal with 'assemble', 'assembleRelease' or 'aR' which creates a new folder in your project root called apk/RELEASE so you don't have to look through build/outputs/more/more/more to find your apk.

Your version properties would need to look like this:

VERSION_NUMBER=1
VERSION_BUILD=645
VERSION_PATCH=1

Obviously start with 0. :)

Answer 5

Another way of getting a versionCode automatically is setting versionCode to the number of commits in the checked out git branch. It accomplishes following objectives:

1. versionCode is generated automatically and consistently on any machine (including a Continuous Integration and/or Continuous Deployment server).
2. App with this versionCode is submittable to GooglePlay.
3. Doesn't rely on any files outside of repo.
4. Doesn't push anything to the repo
5. Can be manually overridden, if needed

Using gradle-git library to accomplish the above objectives. Add code below to your build.gradle file the /app directory:

import org.ajoberstar.grgit.Grgit

repositories {
    mavenCentral()
}

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'org.ajoberstar:grgit:1.5.0'
    }
}

android {
/*
    if you need a build with a custom version, just add it here, but don't commit to repo,
    unless you'd like to disable versionCode to be the number of commits in the current branch.

    ex. project.ext.set("versionCodeManualOverride", 123)
*/
    project.ext.set("versionCodeManualOverride", null)

    defaultConfig {
        versionCode getCustomVersionCode()
    }
}

def getCustomVersionCode() {

    if (project.versionCodeManualOverride != null) {
        return project.versionCodeManualOverride
    }

    // current dir is <your proj>/app, so it's likely that all your git repo files are in the dir
    // above.
    ext.repo = Grgit.open(project.file('..'))

    // should result in the same value as running
    // git rev-list <checked out branch name> | wc -l
    def numOfCommits = ext.repo.log().size()
    return numOfCommits
}

NOTE: For this method to work, it's best to only deploy to Google Play Store from the same branch (ex. master).

Answer 6

Another option, for incrementing the versionCode and the versionName, is using a timestamp.

defaultConfig {
   versionName "${getVersionNameTimestamp()}"
   versionCode getVersionCodeTimestamp()
}


def getVersionNameTimestamp() {
    return new Date().format('yy.MM.ddHHmm')
}

def getVersionCodeTimestamp() {
    def date = new Date()
    def formattedDate = date.format('yyMMddHHmm')
    def code = formattedDate.toInteger()
    println sprintf("VersionCode: %d", code)
    return code
}

Starting on January,1 2022 formattedDate = date.format('yyMMddHHmm') exceeds the capacity of Integers
