Before Starting

This plugin only changes the main app icon on the device homescreen. The icon in springboard and in other areas will not change and continue to show the original. (iOS)

Changing the app icon is only allowed when the app is in the foreground (iOS).

Android support is currently in beta. See the android-support branch for more info.

Installation

npm install @capacitor-community/app-icon
npx cap sync

Configuration

The alternate icons need to be included within the app bundle and referenced in the project prior to using this plugin. It is not possible to switch to any icon on the fly without adding it to the project first. Below are the configurations steps for each platform.

Android Configuration

Add Alternate Icons

Add the alternate icons directly to your android project in app/src/main/res.

Setup ApplicationManifest.xml

Each alternate icon is represented by an <activity-alias>. Add all the alternative icons to the ApplicationManifest.xml as child elements under <application>. The name attribute on <activity-alias> must be prefixed with dot . See ApplicationManifest.xml for full example.

<application>
    <!-- ... -->
    <activity
        android:name=".MainActivity"
        android:exported="true"
        android:launchMode="singleTask"
        android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|smallestScreenSize|screenLayout|uiMode"
        android:label="@string/title_activity_main"
        android:theme="@style/AppTheme.NoActionBarLaunch">

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <!-- <category android:name="android.intent.category.LAUNCHER" /> -->
        </intent-filter>

    </activity>
    <activity-alias
        android:label="Stencil"
        android:icon="@drawable/stencil"
        android:roundIcon="@drawable/stencil"
        android:name=".stencil"
        android:enabled="true"
        android:exported="true"
        android:targetActivity=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity-alias>
  
  <!-- additional <activity-alias> -->

Create the alternate icons in assets catalog

In XCode go to Assets and create the App Icons.
Then fill with images 1024x1024px

The name of the asset should correspond to the name used in the code

Change build settings

1. Visit Build Settings
2. Search For App icon,
3. Select "yes" for Include All App Icon Assets
4. Include a list (in Alternate App Icon Sets) with precise names of the app icons in the Assets Catalogue.

Usage

import { AppIcon } from '@capacitor-community/app-icon';

const changeIcon = async (iconName) => {
  await AppIcon.change({name: iconName, suppressNotification: true});
}

const getName = async () => {
  const { value } = await AppIcon.getName();
  console.log(value);
}

const resetIcon = async () => {
  const disable: string[] = ['stencil']; // all added aliaces names 
  await AppIcon.reset({ suppressNotification: true, disable });
}
