I am making a React Native app. I would like to customize the app icon (meaning the icon that you click on to start the app). I have Googled this, but I keep finding different types of icons that refer to different things. How do I add these types of icons to the app?
This question is related to
icons
react-native
This is helpful for people struggling to find better site to generate icons and splashscreen
You'll need different sized icons for iOS and Android, like Rockvic said. In addition, I recommend this site for generating different sized icons if anybody is interested. You don't need to download anything and it works perfectly.
Hope it helps.
I was able to add an app icon to my react-native android project by following this guy's advice and using Android Asset Studio
Here it is, transcribed in case the link goes dead:
How to upload an Application Icon in React-Native Android
1) Upload your image to Android Asset Studio. Pick whatever effects you’d like to apply. The tool generates a zip file for you. Click Download .Zip.
2) Unzip the file on your machine. Then drag over the images you want to your /android/app/src/main/res/
folder. Make sure to put each image in the right subfolder mipmap-{hdpi, mdpi, xhdpi, xxhdpi, xxxhdpi}.
3) Do not (as I originally did) naively drag and drop the whole folder over your res folder. As you may be removing your /res/values/{strings,styles}.xml
files altogether.
I wrote a generator to automatically generate icons for your react native app from a single icon file. It generates your assets and it also adds them correctly to your ios and android project:
We revamped our generator to be up to date with the ecosystem standards. You can now use @bam.tech/react-native-make.
You can install it using: yarn add @bam.tech/react-native-make
in the react-native project
To use it react-native set-icon --path <path_to_png> --background <icon_background_color> --platform <android|ios>
And... that's it! Hope it can be useful for others :)
Recommendations:
Here are some improvements over the previous tool:
I would use a service to scale the icon correctly. http://makeappicon.com/ seems good. Use a image on the larger size as scaling up a smaller image can lead to the larger icons being pixelated. That site will give you sizes for both iOS and Android.
From there its just a matter of setting the icon like you would a regular native app.
Someone made a very easy to use tool just for this task: https://www.npmjs.com/package/app-icon
This simple tool allows you to create a single icon in your react-native project, then create icons of all required sizes from it. It currently works for iOS and Android.
I've used it. Made a 512x512 png and then ran that tool and boom, done. Super easy.
I would like to suggest to use react-native-vector-icons to import icons to your project. As you use vector icons, you don't need to worry much on icon scaling side. While using the package you are able to use all popular icon set such as fontawesome, ionicons etc..
Besides these iconsets you can also bring your own icons too to your react-native project by packing your icons as a ttf file and you can import that ttf directly to both android and ios project. You can utilise the same react-native-vector-icons library to manage those icons
Here is a detailed procedure to setup custom icons
https://medium.com/bam-tech/add-custom-icons-to-your-react-native-application-f039c244386c
You can import react-native-elements and use the font-awesome icons to your react native app
Install
npm install --save react-native-elements
then import that where you want to use icons
import { Icon } from 'react-native-elements'
Use it like
render() {
return(
<Icon
reverse
name='ios-american-football'
type='ionicon'
color='#517fa4'
/>
);
}
If you're using expo just place an 1024 x 1024 png file in your project and add an icon property to your app.json i.e. "icon": "./src/assets/icon.png"
