Android: add date/time to gradle output apk filename

How to add date/time stamp to Gradle Android output file name?

Should be like project_v0.5.0_201503110212_public.apk

Already looked at

I'm assuming that you want it in the format you specified, so here's one possible solution.

In your gradle file you can define a new function to get the date time string like you desire:

import java.text.DateFormat
import java.text.SimpleDateFormat

def getDateTime() {
    DateFormat df = new SimpleDateFormat("yyyyMMddHHmm");

    return df.format(new Date());
}

Then for all variants you can simply run this:

android {
    //...
  buildTypes {
    //...
    android.applicationVariants.all { variant ->
        variant.outputs.each { output ->
            def file = output.outputFile
            output.outputFile = new File(file.parent, file.name.replace(".apk", "-" + getDateTime() + ".apk"))
        }
    }
  }
}

Note that this doesn't really output the apk name like you posted, but I guess it's enough to help you out.
