Gradle: applicationVariants.all skips one variant

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.

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)
}
