Step by Step Instructions 

1. Open terminal on your computer 

2. Copy the following command: keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000

3. Replace the "my-release-key" with the name of the app and the same as the "alias_name" --> Example: keytool -genkey -v -keystore applicaster.keystore -alias applicaster -keyalg RSA -keysize 2048 -validity 10000

4. After you have edited the command accordingly, copy the command and past it in terminal directly after "user$" 

5. After you press enter the next command will prompt you to enter a keystore password. *As you enter the password the terminal will not show any indication you are typing but the password is being entered.

9. Your keystore file will then be generated

10. Search your computer for the file and save it in a place you can access it again: 

11. Upload the keystore file to your android release build and enter the alias and password you created in the steps above (the store password is the password for the Google Play Console)                                                                                                    

OPTION 2:

Pre-requisites:

For a Release Build on Android we need:

• Keystore File

• Keystore Password

• Key Alias

• Key Password

We can create all of those with a line of code in the Terminal:

keytool -genkey -v -keystore NameOfFile.keystore -storepass KeyStorePassword -alias KeyStoreAlias -keypass KeyPassword -keyalg RSA -keysize 2048 -validity 10000

Change words marked in blue, passwords and names to fit your app.
Copy to the terminal.
Once you copied it to the terminal you will need to answer some questions. 
Answer truthfully.
Once completed the Key Store File will be on your computer.

When running your release build you just need to enter the credentials with which you created the file.
