My AVD created by Android Studio Device Manager is shown up like this:
I want to make it full-screen (no title bar), or shown like a normal Windows maximized app: no anything outside of the Android display area; but all of these are not working:
The only way i found is changing to resolution larger and larger until it is kinda matching the size of the physical display but it's hilarious.
adb shell settings put global policy_control immersive.full=*
This forces the entire system UI (status bar + navigation bar) to hide, making the emulator behave like a fullscreen app.
adb shell settings put global policy_control null
