Duplicating an existing AVD and modifying it by need

If you need a hardware profile based on an existing one, follow these instructions:

1. Select an existing hardware profile and click on Clone Device.
2. Update the hardware profile properties by your needs. To complete the wizard, click on Finish.
3. Your profile appears in the hardware profile list.

Let's go back to the AVD list. Here, you can perform the following operations on any existing AVD:

• Edit it by clicking on Edit
• Delete by right-clicking and choosing Delete
• Access the .ini and .img files on the disk by right-clicking on an AVD instance and choosing Show on Disk
• To view the AVD configuration details, right-click on an AVD instance and choose View Details

Since we covered this, let's go back to the hardware profile list. Here, we can do the following:

• Edit a hardware profile by selecting it and choosing Edit Device
• Delete a hardware profile by right-clicking on it and choosing Delete

Then, we can run or stop an emulator or clear its data as follows:

• To run an emulator that uses an AVD, double-click on the AVD or just choose Launch
• To stop it, right-click on it and choose Stop
• To clear the data for an emulator, and return it to the same state as when it was first defined, right-click on an AVD and choose Wipe Data

We will continue our emulators' journey with the explanation of command-line features that you can use with *-.

To start an emulator, use the emulator command. We will show you some basic command-line syntax to start a virtual device from a terminal:

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

Another command-line syntax is as follows:

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

Let's take a look at the following example:

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

You can specify startup options when you start the emulator; later, you can't set these options.

If you need a list of available AVDs, use this command:

emulator -list-avds

The result is a list of AVD names from the Android home directory. You can override the default home directory by setting the ANDROID_SDK_HOME environment variable.

Stopping an emulator is simple--just close its window.
