So, I want to make an app that usses only some portion of screen, while the rest portion can be used by user. For example, if a user open app through Home Screen Shortcut, app may cover 25% of height while rest 75% will be covered by home screen such that user can use both apps and home screen. Same applies to other scenarios. I am actually trying to create a custom notification panel, hence want my panel to hide the original one. If there is any other way to do this, plz tell me.
