The Android Emulator runs inside Android Studio by default. This
lets you use screen space efficiently, navigate quickly between the
emulator and the editor window using hotkeys, and organize your IDE and
emulator workflow in a single application window.
However, some emulator features are only available when you run it in a
separate window. To launch the emulator in a separate window, go to
File > Settings > Tools > Emulator
(
Android Studio > Preferences > Tools > Emulator
on macOS) and deselect
Launch in a tool window
.
