![]() ![]() Incidentally, the Material Design Color Palette page seems to agree with me, using dark title text on the Lime color I’ve chosen, but using white on almost all other colors. I want to use a light color for the toolbar background even while using the dark theme. So I’ll need to make the text and icons on my toolbar dark instead of the default white from the light theme. My main theme derives from Theme.AppCompat (not ), which is the dark Material theme for older devices, because I want most of the UI to be Update: I originally used Theme.AppCompat, manually setting windowActionBar to false, before learning of here, but I don’t notice any difference)īut that dark theme gives me light text and icons on the my light background of the App Bar: It took me ages to figure out how to do this, so hopefully the following explanation saves someone some time. So now I finally have dark text and icons on my light background in the dark theme: It seems normal to provide a whole new overflow icon for your app, replacing the standard one, just to get the right color.Īndroid’s new Toolbar, which replaces ActionBar (with some awkward code), makes it easier to change the title text color and the color of the menu overflow icon (and the Up/Back icon). It’s fairly easy to change the ActionBar‘s text color, but changing the color of its overflow icon is harder. Arguably this might be unwise design anyway, but there’s nothing in the Material design guidelines advising against it. If you want to use the light theme but want your App Bar to have a dark background, or use a dark theme and want your toolbar to have a light background, things get awkward. This is true of both the Holo themes and the new Material themes. The dark theme expects your App Bar to have a dark background color, so it gives you a white title and white overflow menu icon: The light theme expects your App Bar 1 (Toolbar or ActionBar) to have a light background color, so it gives you a dark title and dark overflow menu icon (the three vertical dots): Let me know in the comments if I’ve missed anything.Android’s has normal (dark) and light themes, though it’s actually the light themes which are normally show in examples of the new Material design. ![]() I haven’t tried it myself though, but in theory, it should work just fine. If you like to automate the process of adding an app icon to your React Native app more and feel adventurous, you can try and use an open-source npm package that will do all these steps for you (e.g. Also, make sure your initial image is 512x512px since this size is required when you upload the.

Protip: Use a free app icon generator that you can find online to generate all the different image sizes for you. Not all of them are mandatory, but Apple highly recommends you to add everything. 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. Open your ejected React Native app (the iOS version) in Xcode and locate the aforementioned Image.xcassets folder. There’s an existing default AppIcon image in the asset catalog already created for you in the Image.xcassets folder. Uploading an app logo for iOS in React Native follows the exact same process as for the apps developed in Swift. How to Add a React Native App Icon to iOS We’re doing this very frequently, with every app template that we release, so I decided to document the process, to help out React Native developers who are still ramping up with app development. Anyone who is building a React Native app will eventually need to solve the issue of adding a React Native app icon to their mobile apps, prior to publishing them to the app stores.Īt Instamobile, we add beautiful app icons to all of our React Native templates, across both platforms: iOS and Android.
