Is app-release.apk zipaligned apk?

Question

I am using Android Studio 1.0.2. When I click assembleRelease in gradle tasks, two files are generated, app-release-unaligned.apk and app-release.apk. I know app-release-unaligned.apk is unaligned but what is app-release.apk? Is it aligned apk? My build.gradle is like below.

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
        signingConfig signingConfigs.config
        zipAlignEnabled true // Is this necessary or not in Android Studio 1.0.2?
    }
}

Even if I didn't put zipAlignEnabled true, app-release.apk is generated. Is it still necessary in Android Studio 1.0.2? All information I get about zipalign is before Android Studio 1.0 comes out.

Answer 1

You don't need to set that flag.

The possible properties and their default values are:

Answer 2

It is both aligned and signed. Ready for publication.

AFAIK zipAlignEnabled is true by default for release builds.
