Depends on what you are referring to. If Linux Mobile, Android apps can be run on Waydroid and there is a compatibility layer like Wine available. However, for Linux Mobile, you'll open up Gnome and KDE apps. In Plasma, you have kirigami which enables convergent apps (that work on desktop, mobile and tablet). As it matures, more apps will be developed that supports it.
The world and ecosystem now doesn't define the ecosystems of the future.
