Question

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

If you want to avoid hardcoding your keystore & password in build.gradle, you can use a properties file as explained here: HANDLING SIGNING CONFIGS WITH GRADLE

Basically:

1) create a myproject.properties file at /home/[username]/.signing with such contents:

keystore=[path to]\release.keystore
keystore.password=*********
keyAlias=***********
keyPassword=********

2) create a gradle.properties file (perhaps at the root of your project directory) with the contents:

MyProject.properties=/home/[username]/.signing/myproject.properties

3) refer to it in your build.gradle like this:

    if(project.hasProperty("MyProject.properties")
        && new File(project.property("MyProject.properties")).exists()) {

    Properties props = new Properties()
    props.load(new FileInputStream(file(project.property("MyProject.properties"))))

    signingConfigs {
        release {
            storeFile file(props['keystore'])
            storePassword props['keystore.password']
            keyAlias props['keyAlias']
            keyPassword props['keyPassword']
        }
    }
}
