Before submitting the application, we need to make sure that we have:

• Set the name of the application
• Set the proper bundle identifier
• Set the app icons

The name and the bundle identifier of the application can be changed using the react-native-rename npm package

To generate the app icons, we can use a service like AppIcon (not sponsored).

Prepare for Play Store

• Application name
• Language
• Privacy policy (app.privacypolicies.com)
• App category
• Short description (80 characters at most, this will be displayed on the top of the description box)
• Full description (Up to 4000 characters, this will be displayed after expanding the description section. Pretty important to have a good one)
• App icon (Transparent PNG or JPEG, up to 1MB, 512px by 512px). We can use the free version of canva.com to create it
• Feature graphic (PNG or JPEG, up to 1MB, 1024px by 500px) - I used free version of canva.com to create it
• Phone screenshots (At least 2 screenshots but up to 8, PNG or JPEG, up to 8MB, 16:9 or 9:16 aspect ratio, each side between 320px and 3840px) - simply take screenshots from the emulator. It is recommended to have at least 4 screenshots because then our app will be eligible for promotion.
• 7-inch tablet screenshots (Up to 8 screenshots, PNG or JPEG, up to 8MB each, 16:9 or 9:16 aspect ratio, each side between 320px and 3840px ) - as well just take screenshots from the emulator.
• 10-inch tablet screenshots (Up to 8 screenshots, PNG or JPEG, up to 8MB each, 16:9 or 9:16 aspect ratio, each side between 320px and 3840px ) - again just take screenshots from the emulator.
• When releasing new versions:
  • Release name (Only visible to us)
  • Release notes (What changed)
  • And the app bundle
