Autoincrement VersionCode with gradle extra properties

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    android       compileSdkVersion 19     buildToolsVersion  19 0 0       defaultConfig           minSdkVersion 9         targetSdkVersion 19            sourceSets           main               manifest srcFile  AndroidManifest xml              java srcDirs     src               resources srcDirs     src               aidl srcDirs     src               renderscript srcDirs     src               res srcDirs     res               assets srcDirs     assets                        buildTypes           release               runProguard true             proguardFile getDefaultProguardFile  proguard-android-optimize txt               proguardFile  proguard cfg              debuggable false             signingConfig null             zipAlign false                   debug               versionNameSuffix  -DEBUG                      productFlavors           dev               packageName    com swisscom docsafe debug              versionCode getDevVersionCode               versionName getLastVersioName project devVersionCode                    prod               packageName    com swisscom docsafe              versionCode getReleaseVersionCode               versionName getLastVersioName project releaseVersionCode                     task wrapper type  Wrapper        gradleVersion    1 8

Using Gradle Task Graph we can check switch build type   The basic idea is to increment the versionCode on each build  On Each build a counter stored in the version properties file  It will be keep updated on every new APK build and replace versionCode string in the build gradle file with this incremented counter value   apply plugin   com android application   android   compileSdkVersion 25 buildToolsVersion  25 0 2   def versionPropsFile   file  version properties   def versionBuild    Setting default value for versionBuild which is the last incremented value stored in the file    if  versionPropsFile canRead          def Properties versionProps   new Properties       versionProps load new FileInputStream versionPropsFile       versionBuild   versionProps  VERSION BUILD   toInteger     else       throw new FileNotFoundException  Could not read version properties          Wrapping inside a method avoids auto incrementing on every gradle task run  Now it runs only when we build apk   ext autoIncrementBuildNumber          if  versionPropsFile canRead              def Properties versionProps   new Properties           versionProps load new FileInputStream versionPropsFile           versionBuild   versionProps  VERSION BUILD   toInteger     1         versionProps  VERSION BUILD     versionBuild toString           versionProps store versionPropsFile nminSdkVersion 14         targetSdkVersion 21         versionCode 1ewWriter    null        else           throw new FileNotFoundException  Could not read version properties              defaultConfig       minSdkVersion 16     targetSdkVersion 21     versionCode 1     versionName  1 0 0     versionBuild    buildTypes       release           minifyEnabled false         proguardFiles getDefaultProguardFile  proguard-android txt     proguard-rules pro              Hook to check if the release debug task is among the tasks to be executed    Let s make use of it gradle taskGraph whenReady  taskGraph - gt      if  taskGraph hasTask assembleDebug         when run debug task            autoIncrementBuildNumber         else if  taskGraph hasTask assembleRelease        when run release task            autoIncrementBuildNumber                dependencies     compile fileTree dir   libs   include      jar      compile  com android support appcompat-v7 25 3 1      Place the above script inside your build gradle file of main module   Reference Website  http   devdeeds com auto-increment-build-number-using-gradle-in-android   Thanks  amp  Regards

The First Commented code will increment the number while each  Rebuild Project  and save the the value in the  Version Property  file       The Second Commented code will generate new version name of APK file while  Build APKs     android       compileSdkVersion 28     buildToolsVersion  29 0 0                                  START                                       def Properties versionProps   new Properties       def versionPropsFile   file  version properties       if versionPropsFile exists            versionProps load new FileInputStream versionPropsFile       def code    versionProps  VERSION CODE       0   toInteger     1     versionProps  VERSION CODE     code toString       versionProps store versionPropsFile newWriter    null                                   END                                        defaultConfig           applicationId  com example myapp          minSdkVersion 15         targetSdkVersion 28         versionCode 1         versionName  0 19          testInstrumentationRunner  android support test runner AndroidJUnitRunner            buildTypes           release               minifyEnabled false             proguardFiles getDefaultProguardFile  proguard-android-optimize txt     proguard-rules pro                                                       START                                                            android applicationVariants all   variant - gt                  variant outputs all                       def appName    MyAppSampleName                      outputFileName   appName   v  variant versionName    versionProps  VERSION CODE    apk                                                                                       END

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

There are two solutions I really like  The first depends on the Play Store and the other depends on Git   Using the Play Store  you can increment the version code by looking at the highest available uploaded version code  The benefit of this solution is that an APK upload will never fail since your version code is always one higher than whatever is on the Play Store  The downside is that distributing your APK outside of the Play Store becomes more difficult  You can set this up using Gradle Play Publisher by following the quickstart guide and telling the plugin to resolve version codes automatically   plugins       id  com android application      id  com github triplet play  version  x x x     android              play       serviceAccountCredentials   file  your-credentials json       resolutionStrategy    auto      Using Git  you can increment the version code based on how many commits and tags your repository has  The benefit here is that your output is reproducible and doesn t depend on anything outside your repo  The downside is that you have to make a new commit or tag to bump your version code  You can set this up by adding the Version Master Gradle plugin   plugins       id  com android application      id  com supercilex gradle versions  version  x x x     android

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 -

I would like to read the versionCode from an external file   I am sure that there are any number of possible solutions  here is one   android       compileSdkVersion 18     buildToolsVersion  18 1 0       def versionPropsFile   file  version properties        if  versionPropsFile canRead              def Properties versionProps   new Properties            versionProps load new FileInputStream versionPropsFile            def code   versionProps  VERSION CODE   toInteger     1          versionProps  VERSION CODE   code toString           versionProps store versionPropsFile newWriter    null           defaultConfig               versionCode code             versionName  1 1              minSdkVersion 14             targetSdkVersion 18                     else           throw new GradleException  Could not read version properties                  rest of android block goes here     This code expects an existing version properties file  which you would create by hand before the first build to have VERSION CODE 8   This code simply bumps the version code on each build -- you would need to extend the technique to handle your per-flavor version code   You can see the Versioning sample project that demonstrates this code

I looked at a few options to do this  and ultimately decided it was simpler to just use the current time for the versionCode instead of trying to automatically increment the versionCode and check it into my revision control system   Add the following to your build gradle          Use the number of seconds 10 since Jan 1 2016 as the versionCode     This lets us upload a new build at most every 10 seconds for the    next 680 years      def vcode    int    new Date   getTime   1000  - 1451606400    10   android       defaultConfig                       versionCode vcode           However  if you expect to upload builds beyond year 2696  you may want to use a different solution

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    versionCode is generated automatically and consistently on any machine  including a Continuous Integration and or Continuous Deployment server   App with this versionCode is submittable to GooglePlay  Doesn t rely on any files outside of repo  Doesn t push anything to the repo 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  lt your proj gt  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  lt checked out branch name gt    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

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

To increment versionCode only in release version do it   android       compileSdkVersion 21     buildToolsVersion  21 1 2       def versionPropsFile   file  version properties       def code   1      if  versionPropsFile canRead              def Properties versionProps   new Properties            versionProps load new FileInputStream versionPropsFile           List lt String gt  runTasks   gradle startParameter getTaskNames            def value   0         for  String item   runTasks          if   item contains  assembleRelease                  value   1                    code   Integer parseInt versionProps  VERSION CODE    intValue     value         versionProps  VERSION CODE   code toString           versionProps store versionPropsFile newWriter    null            else           throw new GradleException  Could not read version properties               defaultConfig           applicationId  com pack          minSdkVersion 14         targetSdkVersion 21         versionName  1 0    code         versionCode code         expects an existing c   YourProject app version properties file  which you would create by hand before the first build to have VERSION CODE 8  File  version properties   VERSION CODE 8
