Gradle: applicationVariants.all skips one variant

Question

I'm using Gradle to compile my Android project:

buildTypes {
    release {
        signingConfig signingConfigs.release 
        applicationVariants.all { variant ->
            def file = variant.outputFile
            def fileName = file.name
            fileName = fileName.replace(".apk", "-renamed.apk")
            variant.outputFile = new File(file.parent, fileName)
        }
    }
}

Not all output files are renamed, it always skips 1 file. Why?

myapp-debug-unaligned-renamed.apk    <-renamed, OK!
myapp-release.apk                    <-NOT renamed, WRONG!
myapp-release-unaligned-renamed.apk  <-renamed, OK!

I solved using this code:

buildTypes {
    release {
        signingConfig signingConfigs.release 
    }

    applicationVariants.all { variant ->
        def apk = variant.packageApplication.outputFile;
        def newName = apk.name.replace(".apk", "-renamed.apk");
        variant.packageApplication.outputFile = new File(apk.parentFile, newName);
        if (variant.zipAlign) {
            variant.zipAlign.outputFile = new File(apk.parentFile, newName.replace("-unaligned", ""));
        }
    }
}

The block applicationVariants.all {...} is now outside the release {...} block.

I think variant.zipAlign.outputFile makes the difference.

The syntax has changed with the 1.0.0 version of the gradle plugin. See updated solution here: http://stackoverflow.com/questions/23693309/renaming-apk-in-gradle/27369185#27369185 — Nebu, Dec 09 '14 at 00:02

There should be 3 output APK files when using your build.gradle configuration: debug unsigned unaligned, release signed aligned and release signed unaligned. There are two variables for applicationVariant to deal with output files: outputFile and packageApplication.outputFile, the former is used for zipalign and the later is used in general case.

So the proper way to rename all the files will be like this:

android.applicationVariants.all { variant ->
    if (variant.zipAlign) {
        def oldFile = variant.outputFile;
        def newFile = oldFile.name.replace(".apk", "-renamed.apk")
        variant.outputFile = new File(oldFile.parent, newFile)
    }

    def oldFile = variant.packageApplication.outputFile;
    def newFile = oldFile.name.replace(".apk", "-renamed.apk")
    variant.packageApplication.outputFile = new File(oldFile.parent, newFile)
}

I simplified it by removing one of your lines but essentially you need to change it like so:

android {

    buildTypes {
    ...
    }

    applicationVariants.all { variant ->
        def file = variant.outputFile
        def fileName = file.name.replace(".apk", "-renamed".apk")
        variant.outputFile = new File(file.parent, fileName)
    }
}

bringing out the code from the buildTypes {} block does not solve the problem. – Seraphim's Sep 05 '13 at 12:12
variants have outputFiles (plural) now. – Joe Bowbeer Oct 16 '15 at 03:31
