Don't use the manifest to store user specific identifiers, or other other data that might be customized. Note: Since the WebAPK is regenerated each time an updated manifest is detected, we recommend changing it only when necessary. When an update to the manifest is detected, Chrome will need to generate a new APK. To generate the WebAPK, Chrome looks at the web app manifest and other metadata. Being installed via an APK makes it possible for your app to show up in the app launcher, in Android's app settings and to register a set of intent filters. Chrome automatically generates and installs a special APK of your app.

Installing a PWA on Android does more than just add the Progressive Web App to the user's Home Screen.
