Package name is the reversed domain name, it is a unique name for each application on Playstore. You can't upload two apps with the same package name. You can check package name of the app from playstore url

https://play.google.com/store/apps/details?id=package_name

so you can easily check on playstore that this package name is in used by some other app or not before uploading it.

As you stated  package names are usually in the form of  com organizationName appName  - all lowercase and no spaces   It sounds like the package name that you entered when uploading the app was different from the one declared in the AndroidManifest

Visit https   developers google com mobile add and try to fill  Android package name   In some cases it can write error   Invalid Android package name    In https   developer android com studio build application-id html it is written      And although the application ID looks like a traditional Java package   name  the naming rules for the application ID are a bit more   restrictive          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         So   0com example app  and  com 1example app  are errors

As stated here   Package names are written in all lower case to avoid conflict with the names of classes or interfaces   Companies use their reversed Internet domain name to begin their package names   for example  com example mypackage for a package named mypackage created by a programmer at example com   Name collisions that occur within a single company need to be handled by convention within that company  perhaps by including the region or the project name after the company name  for example  com example region mypackage    Packages in the Java language itself begin with java  or javax   In some cases  the internet domain name may not be a valid package name  This can occur if the domain name contains a hyphen or other special character  if the package name begins with a digit or other character that is illegal to use as the beginning of a Java name  or if the package name contains a reserved Java keyword  such as  int   In this event  the suggested convention is to add an underscore  For example

Android follows the same naming conventions like Java   Naming Conventions  Package names are written in all lower case to avoid conflict with the names of classes or interfaces   Companies use their reversed Internet domain name to begin their package names   for example  com example mypackage for a package named mypackage created by a programmer at example com   Name collisions that occur within a single company need to be handled by convention within that company  perhaps by including the region or the project name after the company name  for example  com example region mypackage    Packages in the Java language itself begin with java  or javax   In some cases  the internet domain name may not be a valid package name  This can occur if the domain name contains a hyphen or other special character  if the package name begins with a digit or other character that is illegal to use as the beginning of a Java name  or if the package name contains a reserved Java keyword  such as  int   In this event  the suggested convention is to add an underscore  For example   Legalizing Package Names          Domain Name                            Package Name Prefix  hyphenated-name example org             org example hyphenated name example int                             int  example 123name example com                     com example  123name
