Use different VersionCode for Debug/Release android gradle build

Me too, but I think defaultConfig.versionCode was set when build.gradle be compiling. It's global static variable, and assigned at compiletime, not runtime.

I think we can intercept gradle task execution, and modify defaultConfig.versionCode at runtime.

After goooooooogle, I found this one works for me: https://gist.github.com/keyboardsurfer/a6a5bcf2b62f9aa41ae2

Here's an updated version:

android {
  defaultConfig { ... }

  applicationVariants.all { variant ->
    if (variant.name == 'debug') {
      variant.outputs.each { output ->
        output.versionCodeOverride = 1
      }
    }
  }
}

To use with Flavors:

applicationVariants.all { variant ->
    def flavor = variant.mergedFlavor
    def name = flavor.getVersionName()
    def code = flavor.getVersionCode()

    if (variant.buildType.isDebuggable()) {
        name += '-d'
        code = 1
    }

    variant.outputs.each { output ->
        output.versionNameOverride = name
        output.versionCodeOverride = code
    }
}

Late on the party...

The entire gradle file evaluated before any task execution, so you are basically changing the default versionCode while declaring debug configs. There is no direct way to reset versionCode from buildType, but the link on the other answer do the trick by declaring a task on build variants.

android {
    ...
    defaultConfig {
         ...
    }
    buildTypes {
         ...
    }
    applicationVariants.all { variant ->
        def flavor = variant.mergedFlavor
        def versionCode = flavor.versionCode
        if (variant.buildType.isDebuggable()) {
            versionCode += 1
        }
        flavor.versionCode = versionCode
    }
}
