How to start emulator through command promt

Starting the emulator

---

Use the emulator command to start the emulator, as an alternative to running your project or starting it through the AVD Manager.

Here's the basic command-line syntax for starting a virtual device from a terminal prompt:

emulator -avd avd_name [ {-option [value]} … ]

Or

emulator @avd_name [ {-option [value]} … ]

For example, if you launch the emulator from within Android Studio running on a Mac, the default command line will be similar to the following:

$ /Users/janedoe/Library/Android/sdk/tools/emulator -avd Nexus_5X_API_23 -netdelay none -netspeed full

You can specify startup options when you start the emulator, but not later on.

For a list of AVD names, enter the following command:

emulator -list-avds
