android tutorial - Configure the build gradle with signing configuration in android | Developer android - android app development - android studio - android app developement

You can define the signing configuration to sign the apk in the build.gradle file. You can define

storeFile

: the keystore file

storePassword

: the keystore password

keyAlias

a key alias name

keyPassword

: A key alias password

You have to define the signingConfigs block to create a signing configuration:

android {
    signingConfigs {

        myConfig {
            storeFile file("myFile.keystore")
            storePassword "myPasswork"
            keyAlias "aKeyAlias"
            keyPassword "myAliasPassword"
        }
    }
    //....
}

Then you can assign it to one or more build types.

android {

    buildTypes {
        release {
            signingConfig signingConfigs.myConfig
        }
    }
}
