Question

What does it mean and need whether we are uploading our app into the market? Please Explain or give me a related links.

Answer 1

Starting with Google Play 4.9, the app info display has been changed and the promo graphic is displayed at the top.

The promo graphic will be required soon.

The promo text has turned into a short description and is now shown on the main info page, before the user presses it to view the full description.
