Package Identifier

Package Identifier is almost like an ID and it is unique. It is used to identify apps on your device and on Google Play Store.

Creating Package Identifier

In order to create package identifier, you must follow this naming rules:

  • 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_].

These are the examples of a valid package identifier:

com.stackideas.easysocial

hello.world.cool

isketam.bo.la

Check For Availibility

Package Identifier should be unique. If two applications have the same Package Identifier, you won't be able to upload the APK file in Google Play Store. Kindly follow the steps below to check for availibility.

  1. Copy this URL and paste on your browser's address bar: https://play.google.com/store/apps/details?id=com.example.myapp.
  2. Replace com.example.myapp with your own package identifier.
  3. Hit Enter. If you see another app page, means your package identifier is already being used and it is not available.
