So build file would be looks like below.KeyPassword nsole().readLIne(' Key password: ') StorePassword nsole().readLine(' Keystore password: ') You can get the passwords from nsole().To solve the security issue, you can specify the build process prompt you for these passwords(If you are building from command line) In above signing config I have defined all key-store and key passwords in my gradle file, it is not a good security practice It will generate release apk - Score/senz/build/apk/senz-release.apk Now execute following command from command line.Then define key-store details in adle file(it need to add under android section in build file).First copy release key-store in to senz app.I have senz app under Score project, I'm define signing configs in adle file in senz app(since it is my main app).Rest of this article gives you detailed information about specifying release signing config In debug version you don't need to specify any of these details, it automatically takes debug certificate detailsīut build system does not sign the release version unless you explicitly define a signing configuration for the build, so in release type you have to specify above details in gradle build file

In gradle based android projects, the signing configuration should be specified in the gradle build scriptsįollowing are the details that need to be specify in gradle build script More information about signing android application In release mode you sign the app with your own certificate (actually you have to generate your own key store) This certificate locates on $HOME/.android/debug.keystore

This certificate has a private key with a known password In debug mode, you sign your app with a debug certificate generated by the Android SDK tools. There are two types of signing modes debug mode and release mode This certificate need not to be signed by certificate authority(you can use self signed certificate) Android apps required to digitally signed with a certificate before installingĪndroid identifies author of the app using this certificate,
