I think francis-bacon solution is right I don't see why you would install the emulator in a system image folder as faizann-gagan wrote but it is partial: you may have noticed that many components of the SDK has a package.
Platforms, docs, tools Without this file, the SDK manager will show the component as missing as long as it is not present. Problem is, when you unzip the emulator package, you won't find a package. I guess it is added by the SDK manager upon installation completion. I could get a copy of this file from a backup and modified the version number to match the one in source. Failed packages: - Android Emulator emulator. So I faced almost similar error today but it was about updating the emulator itself.
Cause was the folder Android tried to download the file needed root permissions to access it. So here is what I did:. So, one need to have at least 3. I stress this only, because I did a distro upgrade after that I have also had the same error of the emulator failing to install from android studio. I tried downloading the zip and extract it in the SDK as per the top solutions It also didnt work. I just fixed it by allowing android studio through windows firewall and controlled folder access now it downloaded successfully in android studio.
I'm on Android Studio 3. After emulator update Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow.

What are the issues you have experienced with Android Studio, exactly? What steps did you attempt? What documentation did you read and follow? I was trying to add an emulator to the studio and it would always give errors and it was displaying the link from which it was downloading the files So I took the link and manually downloaded the zip file..
But now how to make it work with the studio Ok thanks very much I solved it myself Only the downloaded files need to be put in the sdk folder and then we create the emulator, it detects the dowloaded image — Faizaan Gagan. You may post an answer to your question and mark it as accepted so that others would know that such a question has a working solution. Otherwise you may delete your question if you think that it does not provide any benefit to general audience that way you will remove the downvotes as well, if I am not mistaken.
The method given by Faizan worked for me to the T. I have used a download manager to get the zip file and extracted it in the correct folder. When creating the virtual device just make sure you refresh the list of where system images are listed in the create new device window. Don't click on download again. Add a comment. Android 11 and higher supports the following additional Android Emulator camera capabilities:. You can use the virtual scene camera in a virtual environment to experiment with augmented reality AR apps made with ARCore.
For information on using the virtual scene camera in the emulator, see Run AR apps in Android Emulator. This feature can be used to import custom images such as QR codes for use with any camera-based app. For more information, see Add Augmented Images to the scene. You can greatly reduce the time it takes to test common AR actions by using the preset macros in the emulator. For example, you can use a macro to reset all the device's sensors to their default state. Before using macros, follow the steps in Run AR apps in Android Emulator to set up the virtual scene camera for your app, run your app on the emulator, and update ARCore.
Then, follow these steps to use emulator macros:. Use the extended controls to send data, change device properties, control apps, and more. To open the Extended controls window, click More in the emulator panel. You can use keyboard shortcuts to perform many of these tasks. The emulator lets you simulate "my location" information: the location where the emulated device is currently located. For example, if you click My Location in Google Maps and then send a location, the map shows it.
Controls for the device's location information are organized under two tabs: Single points and Routes. In the Single points tab, you can use the Google Maps webview to search for points of interest, just as you would when using Google Maps on a phone or in a browser. When you search for or click on a location in the map, you can save the location by selecting Save point near the bottom of the map.
All of your saved locations are listed on the right side of the Extended controls window. To set the emulators location to the location you have selected on the map, click the Set location button near the bottom right of the Extended controls window.
Similar to the Single points tab, the Routes tab provides a Google Maps webview that you can use to create a route between two or more locations. To create and save a route, do the following:. To simulate the emulator following the route you saved, select the route from the list of Saved routes and click Play route near the bottom right of the Extended controls window.
To stop the simulation, click Stop route. To continuously simulate the emulator following the specified route, enable the switch next to Repeat playback. To change how quickly the emulator follows the specified route, select an option from the Playback speed dropdown. The speed defaults to the Delay value Speed 1X. You can increase the speed by double Speed 2X , triple Speed 3X , and so on.
The emulator allows you to deploy your app to multiple displays, which support customizable dimensions and can help you test apps that support multi- window and multi- display. While a virtual device is running, you can add up to two additional displays as follows:. The emulator lets you simulate various network conditions. You can approximate the network speed for different network protocols, or you can specify Full , which transfers data as quickly as your computer allows.
Specifying a network protocol is always slower than Full. You can also specify the voice and data network status, such as roaming. The defaults are set in the AVD. You can simulate the battery properties of a device to see how your app performs under different conditions.
To select a Charge level , use the slider control. If the AVD has the directional pad enabled in the hardware profile, you can use the directional pad controls with the emulator. However, not all devices can support the directional pad; for example, an Android watch.
The buttons simulate the following actions:. This control can simulate 10 different fingerprint scans. You can use it to test fingerprint integration in your app. This feature is disabled for Android 5. This control lets you test your app against changes in device position, orientation, or both. For example, you can simulate gestures such as tilt and rotation. The accelerometer doesn't track the absolute position of the device: it just detects when a change is occurring.
The control simulates the way accelerometer and magnetometer sensors would respond when you move or rotate a real device. You must enable the accelerometer sensor in your AVD to use this control. These values include gravity. For example, if the device is suspended in outer space, it would experience zero acceleration all of x, y, and z will be 0. When the device is on Earth and laying screen-up on top of a table, the acceleration is 0, 0, and 9.
To rotate the device around the x, y, and z axes, select Rotate and do one of the following:. See Computing the device's orientation for more information about how yaw, pitch, and roll are calculated. To move the device horizontally x or vertically y , select Move and do one of the following:. As you adjust the device, the Resulting values fields change accordingly. These are the values that an app can access.
For more information about these sensors, see Sensors overview , Motion sensors , and Position sensors. The emulator can simulate various position and environment sensors. It lets you adjust the following sensors so you can test them with your app:.
For more information about these sensors, see Sensors overview , Position sensors , and Environment sensors. For more information, see Using the emulator with a proxy. This is equivalant to the -gpu command line option. Autodetect based on host : Let the emulator choose hardware or software graphics acceleration based on your computer setup. SwiftShader : Use SwiftShader to render graphics in software. This option is typically the fastest. However, some drivers have issues with rendering OpenGL graphics, so it might not be a reliable option.
For the shortcuts to work, the Send keyboard shortcuts option in the General settings pane must be set to Emulator controls default. To file a bug against the emulator, click Send feedback.
For more information, see how to report emulator bugs. Compare the latest available emulator version with your version to determine if you have the latest software installed. You can disable Wi-Fi in the emulator by running the emulator with the command-line parameter -feature -Wifi.

Requirements and recommendations The Android Emulator has additional requirements beyond the basic system requirements for Android Studio , which are described below: SDK Tools Android virtual devices Each instance of the Android Emulator uses an Android virtual device AVD to specify the Android version and hardware characteristics of the simulated device.
Run an app on the Android Emulator You can run an app from an Android Studio project, or you can run an app that's been installed on the Android Emulator as you would run any app on a device. Double-click an AVD, or click Run. The Android Emulator loads. Run the Android Emulator directly in Android Studio Run the Android Emulator directly in Android Studio to conserve screen real estate, to navigate quickly between the emulator and the editor window using hotkeys, and to organize your IDE and emulator workflow in a single application window.
Start your virtual device using the AVD Manager or by targeting it when running your app. Limitations Currently, you can't use the emulator's extended controls when it's running in a tool window.
Snapshots A snapshot is a stored image of an AVD Android Virtual Device that preserves the entire state of the device at the time that it was saved — including OS settings, application state, and user data. Save Quick Boot snapshots When you close an AVD, you can specify whether the emulator automatically saves a snapshot when you close. To control this behavior, proceed as follows: Open the emulator's Extended controls window.
In the Snapshots category of controls, navigate to the Settings tab. Use the Auto-save current state to Quickboot drop-down menu to select one of the following options: Yes : Always save an AVD snapshot when you close the emulator. No : Don't save an AVD snapshot when you close the emulator. Delete a snapshot To manually delete a snapshot, open the emulator's Extended controls window, select the Snapshots category, select the snapshot, and click the delete button at the bottom of the window.
Load a snapshot To load a snapshot at any time, open the emulator's Extended controls window, select the Snapshots category, choose a snapshot, and click the load button at the bottom of the window. Select Cold boot. Snapshot requirements and troubleshooting Snapshots do not work with Android 4. Snapshots do not work with ARM system images for Android 8. Snapshots are not reliable when software rendering is enabled. Loading or saving a snapshot is a memory-intensive operation. If you do not have enough RAM free when a load or save operation begins, the operating system may swap the contents of RAM to the hard disk, which can greatly slow the operation.
If you experience very slow snapshot loads or saves, you may be able to speed these operations by freeing RAM. Closing applications that are not essential for your work is a good way to free RAM.
