8. Android
Virtual
Devices
• To
run
the
emulator,
you
must
configure
android
virtual
device
• To
open
AVD,
use
command
android avd
• Click
new
to
create
new
AVD

10. Star+ng
the
Emulator
• In
avd,
click
start
Or
• use
emulator –avd
youravd
command
in
command
line

11. Installing
App

compiled
and
packaged
applica+on
can
