react-native-nchange-appicon v1.0.1

• Just upload your images from earlier, and checkmark both iPhone and Android.
• This will give you a .zip file with the files needed.

• You need to rename and sort these files slightly differently for both iOS and Android.

Android 🤖 1. Simply just rename them to something appropriate - typically this follows the naming convention ic_launcher_<type>.png e.g. ic_launcher_dark.png

• Make sure to keep them within the folder structure they are in mipmap-hdpi... etc.

2. Create a single android directory with all the mipmap-* directories inside. Inside them place all your generated icons.

iOS 🍏 1. You will need the generated folder called AppIcon.appiconset as this contains your icons. 2. Rename this folder a bit like above for Android using a naming convention such as <type>.appiconset e.g. Dark.appiconset 3. You will also need to edit the Contents.json to change and references from Assets.xcassets/AppIcon.appiconset to what you have renamed the file now e.g. Images.xcassets/AppIcon.appiconset

Android 🤖 1. Drag all of the mipmap folders into android/app/src/main/res/

iOS 🍏 1. Drag all of the .appiconset folders into ios/<app-name>/Images.xcassets

Android 🤖 1. Add an alias for each of your new icons within the AndroidManifest.xml (within <application>).

• Make sure these have the properties as shown below.
• Create an alias for .MainActivityDefault as well but for this, set android:enabled="true".
• For the name prefix it .MainActivity... followed by the name you will use to reference your icon. e.g. for our light icon we will use .MainActivityLight

2. You'll have to remove the LAUNCHER intent filter from the main <activity> as we have added the launcher in .MainActivityDefault.

<activity-alias 
	android:name=".MainActivityLight"
	android:enabled="false"
	android:exported="true"
	android:icon="@mipmap/ic_launcher_light"
	android:targetActivity=".MainActivity">
	<intent-filter>
		<action android:name="android.intent.action.MAIN" />
		<category android:name="android.intent.category.LAUNCHER" />
	</intent-filter>
	</activity-alias>

iOS 🍏 1. At the bottom of your Info.plist insert a key for CFBundleIcons

• Note: For iPad, you need to add the key CFBundleIcons~ipad

2. Within this dictionary add another key for CFBundleAlternateIcons
3. Finally then within this dictionary you can add in the keys for you new icons
   • The key is the name you will reference from within code.
   • Set the first array item to the name of the .appiconset we created earlier.
4. In XCode, in your app's General settings, under App Icons and Launch Screen, set "App Icon" to Default and check the "Include all app icon assets" checkbox below.

<key>Dark</key>
<dict>
	<key>CFBundleIconFiles</key>
	<array>
		<string>Dark</string>
	</array>
	<key>UIPrerenderedIcon</key>
	<false/>
</dict>

import { changeIcon, getIcon, resetIcon } from 'react-native-change-appicon';

// Pass the name of icon to be enabled
changeIcon('Dark');
changeIcon('Light');

// Get the icon currently enabled
getIcon();

// Reset the Icon to the default
resetIcon();

All functions are typed and return a promise that either resolves successfully, or will reject with the error that has occurred.

react-native-push-notification

When using react-native-push-notification, notifications won't work as we are using activity-alias.

To fix this, you need to create a Java file for each of the activity-alias in your AndroidManifest.xml.

The file should be placed alongside you MainActivity.java. Example:

android/app/src/main/java/com/myapp/MainActivity<KEY>.java

The content of this file should be:

package com.myapp;
public class MainActivity<KEY> extends MainActivity {}

Replace <KEY> with the icon name used in the manifest. Replace com.myapp with your android app structure.
