How to create a release signed apk file using Gradle?

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

In newer Android Studio, there is a GUI way which is very easy and it populates Gradle file as well.

1. File -> Project Structure

2. Module -> Choose the main module ('app' or other custom name)

3. Signing tab -> Plus image to add new configuration

4. Fill data on the right side

5. OK and Gradle file is automatically created

6. You will manually have to add a line signingConfig signingConfigs.NameOfYourConfig inside builtTypes{release{}}

Two important(!) notes:

(EDIT 12/15)

1. To create signed APK, you'd have to open Terminal tab of Android Studio (the bottom of the main interface) and issue a command ./gradlew assembleRelease

2. If you forgot keyAlias (what happens often to me), you will have to initiate Build -> Generate Signed APK to start the process and see the name of the Alias key.
