In the next image you can see the resources of an Android project (using Xamarin under Visual Studio 2017):

The idea is to generate an icon for each folder, from the smallest one (mipmap-mdpi) to the biggest (mipmap-xxxhdpi). Doing this you will be sure to have the best icon for each screen resolution, consuming the minimum amount of memory.
For iOS there are even more icon resolution to create, 25 to be precise!!! In the next image you can see the Asset Catalog of an iOS project (using Xamarin under Visual Studio 2017):

In total, given your original icon, you should resize and generate 30 icons to consider all the resolutions on Android and iOS.
At this point you have 2 options:
- 😭 Spend 1 hour to manually resize your icons 😭
- 😊 Use AppIconHero that automatically will create your icons in just 1 or few seconds (I'm surely there are no app faster than AppIconHero) 😊
Drag your icon over the grey box with the text: “Drag and drop your icon here”. You will see a preview of your icon. Select if you want to generate the icons for Android and/or iOS (by default the tools will generate the icons for Android and iOS). Now press the GENERATE button to download your icons. In just an instant your icons will be ready to be downloaded inside a zip file.
Inside the zip file, the icons are already their correct folders, so you just need to copy these folders inside your Android and iOS projects.
For iOS together with the icons, is also present the file Contents.json. This file is used by iOS to define the Asset Catalog content. It means that if you copy the icons and this file inside your Asset Catalog folder, your project will automatically recognize all the icons.
I hope you enjoy this free tool and if you like I'd appreciate if you could buy me a coffee 😍
