What Is The Package In Android?

I have uploaded my first application to google playstore as you see in this image in manifest in package it says auc.visorimagenes.ssssss in the left part you could see my structur

Solution 1:

Contains information about a Java package. This includes implementation and specification versions. Typically this information is retrieved from the manifest.

Packages are managed by class loaders. All classes loaded by the same loader from the same package share a Package instance.

Hope this helps!

Solution 2:

Could you try and change the android:name attribute of your application entry in the manifest as follows and see if it helps?

<application....android:name=".App"  (orandroid:name=".Application.App")
 />

This will ensure that the app uses the same package name as the one declared in the manifest.

Solution 3:

The package in android is the name of the application that makes it unique from any other android apps, therefore allow the production of multiple apps with the same product name.
