Android Tutorial Signing your application before uploading to Google Play

Thank you, Erel
That topic is solved with your help, but I find that Google asks a lot of things to publish the app. I will try to solve them.
Greetings.

 

Here's a summary:

- the private key stands more for the creator (you) of the app. So it is created once for all of your future apps.
- so you can only update using the same key and a different (higher) version (so loosing the key = no updates anymore = new app)
- if you create several apps, you will use the same private key for all apps
- each app must have a unique package name as it competes with all other apps
- example: us.petersmith.app1, us.petersmith.app2, us.petersmith.app3 (all with the same private key to identify you as the creator)

When I start a new app, I change the package name at once to a unique one (de.xxxxx.mynewapp). The folder where I save the code and the sourcecode has the same name. Very easy. No confusion.

Important: Save the private sign key twice! If it get's lost, you are in trouble (at least you can't update a previous version. It is handled as a new version).

 

Thanks i take note

 

Well, starting this year, I had to upload a new App, Created, compliled, uploaded, no problem.
Two monts ago, I updated an old app, Google play console said it has the wrong signature, go to tools, private sign key, and discover It was configured the debug key.
Today had to update this year's app and again had the same error on Google play console, go to tools, private sign key, and wass correct.

Yeap, an B4A update broken the key config at the beginning of the year and I uploaded an App signed with the Debug key. Had to use debug key to update the app today.

So, Is there a way to change the key without deleting the app from google play?

 

As far as i know, no.

 

Hello,

Until now, I uploaded my apps to my usual google account.

But I have created a company with a friend, to make an app, I will upload it to the google account of the company. Should I create a new private sign key for this app?

Thanks
