Question or issue on macOS: I’m using Apple Mac OS X El Capitan and while trying to install Android Studio 2.0, I encounter following error: Unfortunately while Android Studio Setup tried to Creating Android virtual device, it failed and without ability to retry( How do I complete failed step outside of that Android Studio Setup. What is your Android Virtual Device (AVD) currently, I'm using Pixel 5 from Android Studio for developing android app (on Mac) but the device is so laggy and often runs into issues such as UI not responding.I tried some other virtual devices from Android Studio but they're quite the same.
Android is a very powerful OS that gives a complete set for a smartphone and the options of in-depth access to your cell phone. Android Emulators is an Android Virtual Device that is made to signify any particular Android device. Emulators have become trendy. We can run the Android ecosystem on the Mac Pc and the Windows with emulators for free. Jul 28, 2021 Tip: If you want to launch your app into an emulator, instead run your app from Android Studio and then in the Select Deployment Target dialog that appears, click Create New Virtual Device. To create a new AVD: Open the AVD Manager by clicking Tools AVD Manager. Click Create Virtual Device, at the bottom of the AVD Manager dialog.
- You need to create an AVD to run any app in the Android emulator
- Each AVD is a completely independent virtual device, with its own hardware options, system image, and data storage.
- You create AVD configurations to model different device environments in the Android emulator.
- You can launch a graphical Android AVD Manager either through Eclipse orthrough the
androidtool. Theandroidtool also offersa command-line interface for creating and managing AVDs.

Android Virtual Devices (AVDs) are configurations of emulator options that letyou better model an actual device.
Each AVD is made up of:
- A hardware profile. You can set options to define the hardwarefeatures of the virtual device. For example, you can define whether the devicehas a camera, whether it uses a physical QWERTY keyboard or a dialing pad, howmuch memory it has, and so on.
- A mapping to a system image. You can define what version of theAndroid platform will run on the virtual device. You can choose a version of thestandard Android platform or the system image packaged with an SDK add-on.
- Other options. You can specify the emulator skin you want to usewith the AVD, which lets you control the screen dimensions, appearance, and soon. You can also specify the emulated SD card to use with the AVD.
- A dedicated storage area on your development machine, in which is stored thedevice's user data (installed applications, settings, and so on) and emulated SDcard.
You can create as many AVDs as you need, based on the types of devices youwant to model and the Android platforms and external libraries you want to runyour application on.
In addition to the options in an AVD configuration, you can alsospecify emulator command-line options at launch or by using the emulatorconsole to change behaviors or characteristics at run time. For a completereference of emulator options, please see the Emulatordocumentation.
The easiest way to create an AVD is to use the graphical AVD Manager, whichyou can launch from Eclipse or from the command line using theandroid tool. The android tool is provided in thetools/ directory of the Android SDK. Dragon ball xenoverse 2 ppsspp download for android. When you run theandroid tool without options, it launches the graphical AVDManager.
For more information about how to work with AVDs from inside your developmentenvironment, see Developing in Eclipse withADT or Developing inOther IDEs, as appropriate for your environment.
Creating an AVD
The Android SDK does not include any preconfigured AVDs, soyou need to create an AVD before you can run any application in the emulator(even the Hello World application).
The easiest way to create an AVD is to use the graphical AVD Manager, but theandroid tool also offers a command line option.
To create an AVD:
- In Eclipse, choose Window > Android SDK and AVD Manager.
- Select Virtual Devices in the left panel.
- Click New.
- Type the name of the AVD, such as 'my_avd'.
- Choose a target.
- Optionally specify any additional settings:
- SD Card
- The path to the SD card image to use with thisAVD, or the size of a new SD card image to create for this AVD.
- Skin
- The skin to use for this AVD, identified by name or dimensions.
- Hardware
- The hardware emulation options for the device. For a list of the options, see Setting hardware emulation options.
- Click Create AVD.
Alternatively, you can launch the graphical AVD Manager by running theandroid tool with no options.
The Create New AVD dialog appears.
The target is the system image that you want to run on the emulator,from the set of platforms that are installed in your SDK environment. You canchoose a version of the standard Android platform or an SDK add-on. For moreinformation about how to add platforms to your SDK, see Adding SDK Components.
Setting hardware emulation options
When you create a new AVD that uses a standard Android system image ('Type:platform'), the AVD Manager lets you set hardware emulationoptions for your virtual device. The table below lists the options available and thedefault values, as well as the names of properties that store the emulatedhardware options in the AVD's configuration file (the config.ini file in theAVD's local directory).
| Characteristic | Description | Property |
|---|---|---|
| Device ram size | The amount of physical RAM on the device, in megabytes. Default value is '96'. | hw.ramSize |
| Touch-screen support | Whether there is a touch screen or not on the device. Default value is 'yes'. | hw.touchScreen |
| Trackball support | Whether there is a trackball on the device. Default value is 'yes'. | hw.trackBall |

| Cache partition size | Default value is '66MB'. | disk.cachePartition.size |
| Abstracted LCD density | Sets the generalized density characteristic used by the AVD's screen. Mostskins come with a value (which you can modify), but if a skin doesn't provideits own value, the default is 160. | hw.lcd.density |
| Max VM application heap size | The maximum heap size a Dalvik application might allocate before beingkilled by the system. Value is in megabytes. Most skins come with a value (whichyou can modify), but if a skin doesn't provide its own value, the default is16. | vm.heapSize |
Default location of the AVD files
When you create an AVD, the AVD Manager creates a dedicated directory for iton your development computer. The directory contains the AVD configuration file,the user data image and SD card image (if available), and any other filesassociated with the device. Note that the directory does not contain a systemimage — instead, the AVD configuration file contains a mapping to thesystem image, which it loads when the AVD is launched.
The AVD Manager also creates a <AVD name>.ini file for theAVD at the root of the .android/avd directory on your computer. The filespecifies the location of the AVD directory and always remains at the root the.android directory.
By default, the AVD Manager creates the AVD directory inside~/.android/avd/ (on Linux/Mac), C:Documents andSettings<user>.android on Windows XP, and C:Users<user>.android on Windows Vista. Patricia wilbarger brushing program. If you want to use a custom location for the AVD directory, you can do so by using the -p <path> option when you create the AVD (command line tool only):
If the .android directory is hosted on a network drive, we recommend usingthe -p option to place the AVD directory in another location. The AVD's .ini file remains in the .android directory on the networkdrive, regardless of the location of the AVD directory.
Managing AVDs
The sections below provide more information about how to manage AVDs once you've created them.
Moving an AVD
If you want to move or rename an AVD, you can do so using this command:
The options for this command are listed in Command-lineoptions for AVDs at the bottom of this page.
Android Studio Create Virtual Device
Updating an AVD
If you rename or move the root directory of a platform (or add-on), an AVD configured to use that platform will no longer be able to load the system image properly. To fix the AVD, use the Repair.. button in the AVD Manager. From the command line, you can also use the android update avd command to recompute the path to the system images.
Deleting an AVD
You can delete an AVD in the AVD Manager by selecting the AVD and clicking Delete.
Alternatively, you can use the android tool to delete an AVD. Here is the command usage:
When you issue the command, the android tool looks for an AVD matching the specified name deletes the AVD's directory and files.
Command-line options
You can use the android tool to create and manage AVDs.
Android Virtual Device Mac Os
The command line for creating an AVD has the following syntax:
Here's an example that creates an AVD with the name 'my_android2.2' and target ID '3':
The table below lists the command-line options you can use with the android tool.
| Action | Option | Description | Comments |
|---|---|---|---|
list avds | List all known AVDs, with name, path, target, and skin. | ||
create avd | -n <name> or | The name for the AVD. | Required |
-t <targetID> | Target ID of the system image to use with the new AVD. | Required. To obtain a list of available targets, use android list targets. | |
-c <path> or -c <size>[K|M] | The path to the SD card image to use with this AVD or the size of a new SD card image to create for this AVD. | Examples: -c path/to/sdcard or -c 1000M | |
-f | Force creation of the AVD | By default, if the name of the AVD being created matches that of an existing AVD, the android tool will not create the new AVD or overwrite the existing AVD. If you specify the -f option, however, the android tool will automatically overwrite any existing AVD that has the same name as the new AVD. The files and data of the existing AVD are deleted. | |
-p <path> | Path to the location at which to create the directory for this AVD'sfiles. | ||
-s <name> or -s <width>-<height> | The skin to use for this AVD, identified by name or dimensions. | The android tool scans for a matching skin by name or dimension in theskins/ directory of the target referenced in the -t<targetID> argument. Example: -s HVGA-L | |
delete avd | -n <name> | Delete the specified AVD. | Required |
move avd | -n <name> | The name of the AVD to move. | Required |
-p <path> | The path to the new location for the AVD. | ||
-r <new-name> | Rename the AVD. | ||
