TIER 3 --- Large screen ready
| **Objective:** Make your app [large screen ready](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality#large_screen_ready) by meeting the [LS-M1](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality#LS-M1) multi-window mode and [LS-M2](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality#LS-M2) multi-resume requirements of the [Large screen
| app quality](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality) guidelines.

Multi-window mode enables your app to share the same screen simultaneously with
other apps for an enhanced, multitasking user experience. Apps share the screen
in split-screen mode, picture-in-picture mode, or free-form windowing mode.

Multi-resume maintains all activities in the [`RESUMED`](https://developer.android.com/reference/kotlin/androidx/lifecycle/Lifecycle.State#RESUMED) state when the device
is in multi-window mode, even when activities aren't focused. Multi-resume
enables activities to continue processes such as video playback while the user
interacts with other activities.
