AppVersionGradleScript

Gradle Script for Automate app version.

Gradle script is implmented in demo project which is given below.

Steps for Creating Gradle Build Script

1. Create new Resource Bundle file (name : version)

   app > New > Resource Bundle

2. Open version.properties in app module and write below lines in file.

   VERSION_NUMBER=1
   VERSION_MINOR=0
   VERSION_BUILD=0
   VERSION_PATCH=0
   VERSION_MAJOR=0
   

3. Open build.gradle (Module: app) and gradle script lines as shown below.

/**
    * Auto Increment Build Version Script
    */
def versionPropsFile = file('version.properties')

/*Setting default value for versionBuild which is the last incremented value stored in the file */
if (versionPropsFile.canRead()) {
        Properties versionProps = new Properties()
        versionProps.load(new FileInputStream(versionPropsFile))
        def value = 0
        try {
            def releaseBuildTask = getTasks().findByName('assemble').name
            if ('assemble' in releaseBuildTask) {
                value = 1
            }
        } catch(Exception exception) {
            println "Unable to found Release build Running Tasks"
        }
        //Getting Strings from version.properties
        def versionMajor = versionProps['VERSION_MAJOR'].toInteger()
        def versionMinor = versionProps['VERSION_MINOR'].toInteger()
        def versionPatch = versionProps['VERSION_PATCH'].toInteger() + value
        def versionBuild = versionProps['VERSION_BUILD'].toInteger() + 1
        def versionNumber = versionProps['VERSION_NUMBER'].toInteger() + value

        //Saving modified values in version.properties
        versionProps['VERSION_PATCH'] = versionPatch.toString()
        versionProps['VERSION_BUILD'] = versionBuild.toString()
        versionProps['VERSION_NUMBER'] = versionNumber.toString()

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

        defaultConfig {
            applicationId ""
            minSdkVersion 16
            targetSdkVersion 29
            versionCode versionNumber
            versionName "${versionMajor}.${versionMinor}.${versionPatch}.${versionBuild}"
            testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
            multiDexEnabled true
            archivesBaseName = "${applicationId}_v${versionName}"
        }
    } else {
        throw new FileNotFoundException("Could not find version.properties")
    }
