[android] How to create a release signed apk file using Gradle?

I would like to have my Gradle build to create a release signed apk file using Gradle.

I'm not sure if the code is correct or if I'm missing a parameter when doing gradle build?

This is some of the code in my gradle file:

android {
    signingConfigs {
          release {
              storeFile file("release.keystore")
              storePassword "******"
              keyAlias "******"
              keyPassword "******"

The gradle build finishes SUCCESSFUL, and in my build/apk folder I only see the ...-release-unsigned.apk and ...-debug-unaligned.apk files.

Any suggestions on how to solve this?

The answer is

Easier way than previous answers:

Put this into ~/.gradle/gradle.properties

RELEASE_STORE_FILE={path to your keystore}

Modify your app/build.gradle, and add this inside the android { code block:

signingConfigs {

   release {
       storeFile file(RELEASE_STORE_FILE)
       storePassword RELEASE_STORE_PASSWORD
       keyAlias RELEASE_KEY_ALIAS
       keyPassword RELEASE_KEY_PASSWORD

       // Optional, specify signing versions used
       v1SigningEnabled true
       v2SigningEnabled true

buildTypes {
        release {
            signingConfig signingConfigs.release

Then you can run gradle assembleRelease
