I decided to write this tutorial because I spent a lot of time figuring out how to create a functional keystore because of the lack of tutorials on this subject.
The keystore is for you to sign your app before you publish it on google play, it ensures that only you can upload updates to your app.
To generate a keystore you need to download the JDK java, JRE java and an application that will make your life much easier for the android apk signing tool, all of these programs can be downloaded from the site: shatter-box.com / Knowledgebase / android-apk-signing-tool-apk-signer /
After installing the programs and the apk signing tool, you execute the apk tool as administrator and a screen will appear.
The most important data you should keep is the password, alias password and the own alias, if you have memory problems put the name of your key the same as the alias, and the passwords all the same.
Quando voce for compilar um app usando o cocoon.io, na tela:
In the Title field: Enter the name for you to identify on the cocoon io site.
In the alias field: Put the same alias you used to create the key in the apk tool.
In the fields certificate password and alias passwords: Enter the passwords that you used to create the key in the apk tool.
That's all, thanks to everyone who has read this tutorial.
