How to generate a custom Android package

What you need before starting​​

• ​Android Studio installed (Download link : https://developer.android.com/studio)

1: Generate Certificate (.keystore)

Generate a .keystore file to sign your application: Sign your app or Visual Studio

• If you possess a .jks file, it is necessary to convert it into a .keystore file. Below is the command to execute within a terminal. Prior to that, make sure you have keytool or Android Studio installed.
  

  • keytool -importkeystore -srckeystore <alias>.jks -destkeystore <alias>.keystore -srcstorepass <password> -deststorepass <password>

• /!\ If this is not done, rename the file to the name of the alias: "alias.keystore".
• /!\ Avoid including special characters in your password.
