Preparing Your Apps for Release
Before publishing an app on Google Play, you must make sure that it is signed with a release key and that it has the correct version information. Otherwise, you won't be able to publish a new app or an update to an already-published app.
Let's start with adding versions to your app.
Versioning Apps
The version of your app is important for the following reasons:
- Users can see the version they have downloaded. They can use this when checking whether there's an update or whether there are known issues when reporting bugs/problems with the app.
- The device and Google Play use the version value to determine whether an app can or should be updated.
- Developers can also use this value to add feature support in specific versions. They can also warn or force users to upgrade to the latest version to get important fixes on bugs or security issues.
