When we go to export our projects on intel xdk, where we can change the icon of the game?
Open your project in Intel XDK. Click on "Projects" in top-left corner. Under "Cordova hybrid mobile app settings" click on "Launch icons and Splash screens", then select tab "Android-Crosswalk" (if you are building with Crosswalk).
May I need to upload all icon fields? or just choose one?
What is a splash screen?
Develop games in your browser. Powerful, performant & highly capable.
It is recommended to upload all icon fields, so the icon will show on all devices.
Splash screen is an image (a screen) that shows when you open the app.
