This is what happend to my Android app.

It works well when I install and test on my Lenovo IdeaPad Tablet (it could be any other device).

But after I upload the APK to Google Play Store, I could not find the app using the tablet!

After researching, I realized it is to do with the features and permissions declared in the manifest file. Google Play has filtering.

The documentation that you must read is on the uses-feature element.

Key takeaway:

• If you don’t use a feature, you must EXPLICITLY say that required=false!

• Permissions imply Features

Android has grown complex.
