how append date build to versionNameSuffix on gradle

Question

I am using Android Studio and I need to append a suffix to the versionNameSuffix on my Android build.gradle file. I have three different buildTypes and I only need to append the datetime to my "beta" release, my actual file is:

defaultConfig {
    versionCode 14
    versionName "0.7.5"
    minSdkVersion 9
    targetSdkVersion 18
}
buildTypes {
    beta {
        packageNameSuffix ".beta"
        versionNameSuffix "-beta"
        signingConfig signingConfigs.debug
    }
    ....
}

for testing and automatic deploy, I need to get a final versionName like: 0.7.5-beta-build20131004, 0.7.5-beta-build1380855996 or something like that. Any ideas?

Answer 1

beta {
    packageNameSuffix ".beta"
    versionNameSuffix "-beta" + "-build" + getDate()
    signingConfig signingConfigs.debug
}

def getDate() {
    def date = new Date()
    def formattedDate = date.format('yyyyMMddHHmmss')
    return formattedDate
}

Condensed:

def getDate() {
    return new Date().format('yyyyMMddHHmmss')
}

You can define in your build.gradle custom functions and variables.

def versionMajor = 3

def buildTime() {
    def df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm'Z'") // you can change it
    df.setTimeZone(TimeZone.getTimeZone("UTC"))
    return df.format(new Date())
}

Then you can use it:

android {
    defaultConfig {
       versionName "${versionMajor}-beta-build-${buildTime()}"
    }
}

or if you want to add it in you versionNameSuffix

beta {
    versionNameSuffix "-beta-build-${buildTime()}"      
}

Also, do not forget to add import as Gradle first line:

import java.text.SimpleDateFormat;
...

Answer 4

for simple one row solution define this property above android section 

final BUILD_DATE = new Date().format('yyyy_MM_dd_HHmm')

and then 

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion

    defaultConfig {
        applicationId APPLICATION_ID
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.compileSdkVersion
        versionName GIT_TAG_NAME
        versionCode GIT_COMMIT_COUNT
        setProperty("archivesBaseName",`enter code here` "com-appname-$BUILD_DATE-$versionName")
    }
}

Answer 5

I'm not familiar with Android Studio, but I'll assume Gradle behaves as it normally does. Adding something like this to your build project configuration should do the trick:

allProjects {
    gradle.taskGraph.whenReady { taskGraph ->
        versionNameSuffix += '-build' + // Java/Groovy code to produce the timestamp formatted the way you want
    }
}

You can test

task timenow {
    println(new Date().getTime())
}

Run gradle: gradle timenow

See details. Place it on the top-level build

ext {
    configuration = [
            appName          : "vBulletin",
            applicationId    : "com.vbulletin",
            minSdkVersion    : 14,
            targetSdkVersion : 19,
            compileSdkVersion: 19,
            versionCode      : 6,
            versionName      : "1.3.6",
            buildToolsVersion: "25.0.0",
    ]

}

task createBrand {
    appConfig.applicationId = appConfig.applicationId + ".${brand}"
    appConfig.versionCode = new Date().getTime()
    appConfig.versionName = version
}
