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

Answer 1

Extending the answer by David Vavra,create a file ~/.gradle/gradle.properties and add

RELEASE_STORE_FILE=/path/to/.keystore
RELEASE_KEY_ALIAS=XXXXX
RELEASE_STORE_PASSWORD=XXXXXXXXX
RELEASE_KEY_PASSWORD=XXXXXXXXX

Then in build.gradle

  signingConfigs {
    release {
    }
  }

  buildTypes {
    release {
      minifyEnabled true
      shrinkResources true

    }
  }

  // make this optional
  if ( project.hasProperty("RELEASE_KEY_ALIAS") ) {
    signingConfigs {
      release {
        storeFile file(RELEASE_STORE_FILE)
        storePassword RELEASE_STORE_PASSWORD
        keyAlias RELEASE_KEY_ALIAS
        keyPassword RELEASE_KEY_PASSWORD
      }
    }
    buildTypes {
      release {
        signingConfig signingConfigs.release
      }
    }
  }
