You can define the signing configuration to sign the apk in the build.gradle file using these properties:

In many case you may need to avoid this kind of info in the build.gradle file.

Method A: Configure release signing using a file

It’s possible to configure your app’s build.gradle so that it will read your signing configuration information from a properties file like

Setting up signing like this is beneficial because:

First, create a file called in the root of your project with content like this (replacing the values with your own):


Now, in your app’s build.gradle file, set up the signingConfigs block as follows:
