Uploading an app logo for iOS in React Native follows the exact same process as for the apps developed in Swift. There’s an existing default AppIcon image in the asset catalog already created for you in the Image.xcassets folder. Open your ejected React Native app (the iOS version) in Xcode and locate the aforementioned Image.xcassets folder. Then drag and drop your app logo over the AppIcon image.Īs you can see, there are about 20 different image sizes that you need to specify.

There is ic_launcher.png and ic_launcher_round.png. The round version of the launcher icon was brought in for Android 7.0 (Nougat). ANDROID STUDIO APP ICON GENERATOR FOR ANDROID New Android devices can implement the rounded launcher icon feature. (These are the default file names and they can be changed.)

Reminder of Screen Densitiesīefore covering the size of Android launcher icons a summary on screen densities. Over the many years that Android has been around the pixel density of the screens that are supported has increased. The original baseline density was a screen with 160 dots per inch (dpi). Generally one dot on a device screen is known as a pixel (px), so 160 px per inch. Any screens around 160 dpi are referred to as medium density screens, a.k.a. There are high density screens at around 240 dpi, or hdpi, and extra high density screens around 320 dpi, xhdpi. Then it gets a bit crazy with extra extra high density screens around 480 dpi, xxhdpi, and above that extra extra extra high density screens around 640 dpi, xxxhdpi. Icon Sizes for Different Screen Densities Older versions of Android supported a low density screen around 120 dpi, ldpi.
