What do I need for a Google Play store listing?
A complete listing needs an app title (max 30 characters), a short description (max 80), a full description (max 4,000), a 512 x 512 px icon, a 1024 x 500 px feature graphic, at least 2 phone screenshots (up to 8 per device type), a category, contact details and a privacy-policy URL. You must also complete the content rating questionnaire, the Data safety form and the target-audience declaration before you can publish.
