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. Navigate the emulator screen Use your computer mouse pointer to mimic your finger on the touchscreen; select menu items and input fields; and click buttons and controls. Table 1. Gestures for navigating the emulator Feature Description Swipe the screen Point to the screen, press and hold the primary mouse button, swipe across the screen, and then release.

Drag an item Point to an item on the screen, press and hold the primary mouse button, move the item, and then release. Tap touch. Pressing Control Command on Mac brings up a pinch gesture multi-touch interface. The mouse acts as the first finger, and across the anchor point is the second finger. Drag the cursor to move the first point.

Clicking the left mouse button acts like touching down both points, and releasing acts like picking both up. Point to the screen, press and hold the primary mouse button, swipe across the screen, and then release. Point to an item on the screen, press and hold the primary mouse button, move the item, and then release. Point to the screen, press the primary mouse button, and then release. For example, you could click a text field to start typing in it, select an app, or press a button.

The x86 emulator boots and runs at nearly the speed of a physical device, making debugging a breeze on graphics-intensive, processor-hungry apps. Also, with Hyper-V compatibility you can run the emulator side-by-side with the Windows Phone Emulator and other Hyper-V VMs, cutting the time you spend switching between platforms.

The range of sensors, including accelerometer, screen orientation, SD card, battery, multi-touch, GPS, camera, audio, and keyboard help you cut the time and expense of debugging functionality on physical devices. Devices in the market have a diverse set of Android versions, screen sizes, and other hardware properties, making app testing an expensive headache. Our curated set of device profiles represent the most popular hardware in the market, including devices from Samsung, Motorola, Sony, LG, and more.

Run against the latest Android versions, including KitKat and Lollipop. The Visual Studio Emulator for Android fits nicely into your existing Android development environment, with APK and file installation that is as simple as dragging and dropping items on the emulator screen.

Debugging to the emulator is as simple as selecting one of our device profiles from the debug target dropdown and hitting the play button. You even receive updates to the emulator alongside other Visual Studio extensions in the Notification Hub. Take a screenshot of your app for marketing or bug filing. Play back app audio through your computer speakers. Zoom the display to any size. The Android Emulator can be run in a variety of configurations to simulate different devices.

Each configuration is called a virtual device. When you deploy and test your app on the emulator, you select a pre-configured or custom virtual device that simulates a physical Android device such as a Nexus or Pixel phone.

The sections listed below describe how to accelerate the Android emulator for maximum performance, how to use the Android Device Manager to create and customize virtual devices, and how to customize the profile properties of a virtual device.

In addition, a troubleshooting section explains common emulator problems and workarounds. Because the Android Emulator can be prohibitively slow without hardware acceleration, we recommend that you enable hardware acceleration on your computer before you use the emulator.
