Android Gradle - load signing config from external file

Question

In Gradle for Android it seems to be commons practice to define your signing config for release build like this:

android {
    signingConfigs {
        debu         


        

Answer 1

For Kotlin Script (build.gradle.kts)

Put a file signing.properties where the module specific build.gradle.kts is found. Don't forget to add it to your .gitignore file!

signing.properties

storeFilePath=/home/willi/example.keystore
storePassword=secret
keyPassword=secret
keyAlias=myReleaseSigningKey

build.gradle.kts

android {
    // ...
    signingConfigs {
        create("release") {
            val properties = Properties().apply {
                load(File("signing.properties").reader())
            }
            storeFile = File(properties.getProperty("storeFilePath"))
            storePassword = properties.getProperty("storePassword")
            keyPassword = properties.getProperty("keyPassword")
            keyAlias = "release"
        }
    }

    buildTypes {
        getByName("release") {
            signingConfig = signingConfigs.getByName("release")
            // ...
        }
    }
}
