Question

I want the .apk to be built with the following name format (with timestamp).

How can I set it?

format : {app_name}{yyyymmddhis}.apk

Answer 1

in the build.gradle file, you should change/add buildTypes like this:

buildTypes {
      release {
        signingConfig signingConfigs.release
        applicationVariants.all { variant ->
            def file = variant.outputFile
            def date = new Date();
            def formattedDate = date.format('yyyyMMddHHmmss')
            variant.outputFile = new File(
                                    file.parent, 
                                    file.name.replace("-release", "-" + formattedDate)
                                    )
        }
    }       
}

====== EDIT with Android Studio 1.0 ======

If you are using Android Studio 1.0, you will get an error like this:

Error:(78, 0) Could not find property 'outputFile' on com.android.build.gradle.internal.api.ApplicationVariantImpl_Decorated@67e7625f.

You should change the build.Types part to this:

buildTypes {
        release {
            signingConfig signingConfigs.releaseConfig
            applicationVariants.all { variant ->
                variant.outputs.each { output ->
                    def date = new Date();
                    def formattedDate = date.format('yyyyMMddHHmmss')
                    output.outputFile = new File(output.outputFile.parent, 
                                            output.outputFile.name.replace("-release", "-" + formattedDate)
                                            )
                }
            }
        }
    }
