Android Oreo - how do I set Adaptive Icons in Cordova?

Question

Just wondering if anyone been able to set adaptive icons on Cordova for Android Oreo? I'm using the android 6.4.0 and my square icon shrinks to fit the circle. I just want it to not shrink. I don't care if the corners are clipped off from the rounding.

I created the icons as described in https://developer.android.com/studio/write/image-asset-studio.html#create-adaptive, copied them to res/android and use the following configuration:

config.xml:

<widget ... xmlns:android="http://schemas.android.com/apk/res/android">     <platform name="android">         <edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application">             <application android:icon="@mipmap/ic_launcher" android:roundIcon="@mipmap/ic_launcher_round" />         </edit-config>         <resource-file src="res/android/drawable/ic_launcher_background.xml" target="app/src/main/res/drawable/ic_launcher_background.xml" />         <resource-file src="res/android/drawable/ic_launcher_foreground.xml" target="app/src/main/res/drawable/ic_launcher_foreground.xml" />         <resource-file src="res/android/mipmap-anydpi-v26/ic_launcher.xml" target="app/src/main/res/mipmap-anydpi-v26/ic_launcher.xml" />         <resource-file src="res/android/mipmap-anydpi-v26/ic_launcher_round.xml" target="app/src/main/res/mipmap-anydpi-v26/ic_launcher_round.xml" />         <resource-file src="res/android/mipmap-hdpi/ic_launcher.png" target="app/src/main/res/mipmap-hdpi/ic_launcher.png" />         <resource-file src="res/android/mipmap-hdpi/ic_launcher_round.png" target="app/src/main/res/mipmap-hdpi/ic_launcher_round.png" />         <resource-file src="res/android/mipmap-mdpi/ic_launcher.png" target="app/src/main/res/mipmap-mdpi/ic_launcher.png" />         <resource-file src="res/android/mipmap-mdpi/ic_launcher_round.png" target="app/src/main/res/mipmap-mdpi/ic_launcher_round.png" />         <resource-file src="res/android/mipmap-xhdpi/ic_launcher.png" target="app/src/main/res/mipmap-xhdpi/ic_launcher.png" />         <resource-file src="res/android/mipmap-xhdpi/ic_launcher_round.png" target="app/src/main/res/mipmap-xhdpi/ic_launcher_round.png" />         <resource-file src="res/android/mipmap-xxhdpi/ic_launcher.png" target="app/src/main/res/mipmap-xxhdpi/ic_launcher.png" />         <resource-file src="res/android/mipmap-xxhdpi/ic_launcher_round.png" target="app/src/main/res/mipmap-xxhdpi/ic_launcher_round.png" />         <resource-file src="res/android/mipmap-xxxhdpi/ic_launcher.png" target="app/src/main/res/mipmap-xxxhdpi/ic_launcher.png" />         <resource-file src="res/android/mipmap-xxxhdpi/ic_launcher_round.png" target="app/src/main/res/mipmap-xxxhdpi/ic_launcher_round.png" />     </platform>     </widget>

So while the above answers helped me get to an answer, they are either dated or incomplete. So, to help anyone moving forward, this is a complete answer with all the ins and outs I could think of.

Step 1: Create the icons

You'll want to do this using the Image Asset Studio (https://developer.android.com/studio/write/image-asset-studio). There a number of guides on doing this.

Step 2: Move the icons to your ionic/cordova project

Copy the entire res folder into your project. The below example is for ionic v1.

cp -a AndroidStudioProjects/MyApplication4/app/src/main/res MyIonicProject/myapp/resources/android/adaptiveicon 

Step 3: Edit config.xml

First, to use the icons (this is missing from other answers), you need to alter the top widget line. You'll want to add xmlns:android="schemas.android.com/apk/res/android" to it, so it looks like the below. This allows the system to change the AndroidMenifest.xml file.

<widget id="io.ionic.starter" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:android="schemas.android.com/apk/res/android" xmlns:cdv="http://cordova.apache.org/ns/1.0"> 

Next, you'll need to adjust the platform section of your config.xml.

First remove any instances of <icon density= ... /> from the <platform name="android"> section.

Then, Add in the alteration to the Android Manifest file:

<edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application">     <application android:icon="@mipmap/ic_launcher" android:roundIcon="@mipmap/ic_launcher_round" /> </edit-config> 

And lastly, for every file in the new resources/android/adaptiveicon folder, you will need to add a line like this:

<resource-file src="resources/android/adaptiveicon/<folder>/<file>" target="app/src/main/res/<folder>/<file>" /> 

Make sure every file is represented! Your final platform section will probably look like this (this example is for when a PNG is used for both foreground and background):

<platform name="android">     <allow-intent href="market:*" />     <splash density="land-ldpi" src="resources/android/splash/drawable-land-ldpi-screen.png" />     <splash density="land-mdpi" src="resources/android/splash/drawable-land-mdpi-screen.png" />     <splash density="land-hdpi" src="resources/android/splash/drawable-land-hdpi-screen.png" />     <splash density="land-xhdpi" src="resources/android/splash/drawable-land-xhdpi-screen.png" />     <splash density="land-xxhdpi" src="resources/android/splash/drawable-land-xxhdpi-screen.png" />     <splash density="land-xxxhdpi" src="resources/android/splash/drawable-land-xxxhdpi-screen.png" />     <splash density="port-ldpi" src="resources/android/splash/drawable-port-ldpi-screen.png" />     <splash density="port-mdpi" src="resources/android/splash/drawable-port-mdpi-screen.png" />     <splash density="port-hdpi" src="resources/android/splash/drawable-port-hdpi-screen.png" />     <splash density="port-xhdpi" src="resources/android/splash/drawable-port-xhdpi-screen.png" />     <splash density="port-xxhdpi" src="resources/android/splash/drawable-port-xxhdpi-screen.png" />     <splash density="port-xxxhdpi" src="resources/android/splash/drawable-port-xxxhdpi-screen.png" />     <edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application">         <application android:icon="@mipmap/ic_launcher" android:roundIcon="@mipmap/ic_launcher_round" />     </edit-config>     <resource-file src="resources/android/adaptiveicon/drawable/ic_launcher_background.xml" target="app/src/main/res/drawable/ic_launcher_background.xml" />     <resource-file src="resources/android/adaptiveicon/drawable-v24/ic_launcher_foreground.xml"

src="resources/android/adaptiveicon/mipmap-xxxhdpi/ic_launcher_round.png" target="app/src/main/res/mipmap-xxxhdpi/ic_launcher_round.png" /> </platform> 

Step 4: Play it safe, clean the Android platform

Run the following commands to clean the platform.

cd myapp rm -rf platforms/android ionic cordova prepare 

For good measure, fix the bugs with the Android emulator start-up in ionic:

wget https://raw.githubusercontent.com/gegenokitaro/cordova-android/8d497784ac4a40a9689e616cd486c4ed07d3e063/bin/templates/cordova/lib/emulator.js -O platforms/android/cordova/lib/emulator.js 

Step 5: Build!

Build:

ionic cordova build android 

Or Emulate:

ionic cordova emulate android --consolelogs --serverlogs --target "Android8"
