[^1]: **Important:** Once you publish your app, you should never change the Package Name. If you change the Package Name, Google Play Store treats the upload as a completely different app. If you want to upload a new version of your app, you must use the same  Package Name and [signing certificate](https://developer.android.com/studio/publish/app-signing) as when originally published.

[^2]: <mark style="background-color:red;">**This is just an example.**</mark>

    Package names are case sensitive and must meet the following requirements:

    * It must have at least two segments (one or more dots).
    * Each segment must start with a letter.
    * All characters must be alphanumeric or an underscore \[a-zA-Z0-9\_].
