I'm developing Ionic 4 app with angular. But, I have stuck in how to change the default App Icon and Splash Screen. I've already go through the Ionic 4 documentation (https://ionicframework.com/docs/native/splash-screen#usage) but din't find any suitable solution yet. In StakOverflow I've found Lottie Splash Screen which is one kind of solution but not similar how Ionic default Splash screen works. So, do you have any suggestion how to overcome this issue.
I use ionic 3 and I think ionic 4 its the same , in your project folder , you have a resources directory, go in.
To change the default icon , just change the icon.png
by your image, if I remember you need to resize your image (1024*1024).
To change the default splashscreen, its the same (2732*2732).
Don't forget to rename your image (icon.png and splash.png)
And after change, just update your project :
ionic cordova resources
