• After generating all required images, place them in appropriate directories in Android/app/src/main/res/drawable.
• we need to modify the Android/app/src/main/res/drawable/launch_background.xml file. This file will represent the look of our splash screen. If you also have a drawable-v21 directory present, which in my case, was generated together with the whole project, you can remove the mentioned directory or place there the same launch_background.xml file as in the drawable directory.
