Are you tired of trying to capture that perfect screenshot on your Android emulator, only to end up with a blurry or distorted image? Look no further! In this comprehensive guide, we’ll show you how to take a screenshot of your virtual display on an Android emulator using the power of ADB (Android Debug Bridge).
Why Use ADB for Screenshots?
ADB is a powerful command-line tool that allows you to communicate with your Android device or emulator from your computer. By using ADB, you can take screenshots of your virtual display on the emulator without having to physically interact with the device. This method is especially useful when you’re testing apps or debugging issues on multiple devices at once.
Benefits of Using ADB for Screenshots:
- Quick and easy way to capture screenshots of your virtual display
- No need to physically interact with the emulator or device
- Great for testing apps, debugging issues, or demonstrating features
- Works on both Windows and macOS operating systems
Prerequisites:
Before we dive into the instructions, make sure you have the following requirements met:
- An Android emulator set up on your computer
- ADB installed on your computer (comes with Android Studio or can be downloaded separately)
- A basic understanding of command-line interfaces and ADB commands
Step 1: Enable ADB on Your Android Emulator
To take a screenshot using ADB, you need to enable ADB on your Android emulator. Here’s how:
Open the Android Studio and click on the “AVD Manager” button in the top-right corner of the screen.
In the “AVD Manager” window, select the emulator you want to use and click on the “Pencil” icon next to it.
In the “Edit Android Virtual Device” window, click on the “Advanced” tab and select the “Enable ADB integration” checkbox.
Click “OK” to save the changes.
Step 2: Connect to the Emulator using ADB
Now that ADB is enabled on your emulator, let’s connect to it using the command-line interface:
adb connect
Replace with the actual name of your emulator, which can be found in the AVD Manager window.
Step 3: Take a Screenshot of Your Virtual Display
Once connected to the emulator, you can take a screenshot of your virtual display using the following command:
adb shell screencap /sdcard/screenshot.png
This command captures the screenshot and saves it as “screenshot.png” in the SD card directory of the emulator.
Tips and Variations:
- To take a screenshot of a specific window or activity, use the following command:
adb shell screencap -w /sdcard/screenshot.png
Replace with the actual window ID or activity name.
- To take a screenshot of the entire screen, including the navigation bar and status bar, use the following command:
adb shell screencap -d /sdcard/screenshot.png
- To take a screenshot in a different format, such as JPEG or GIF, specify the format in the command:
adb shell screencap /sdcard/screenshot.jpeg
Step 4: Retrieve the Screenshot from the Emulator
Now that the screenshot is captured and saved on the emulator, let’s retrieve it using ADB:
adb pull /sdcard/screenshot.png
This command pulls the screenshot from the emulator and saves it in the current directory on your computer.
Common Issues and Troubleshooting:
Error: Unable to Connect to Emulator
If you encounter an issue connecting to the emulator using ADB, try the following:
- Check that ADB is enabled on the emulator
- Verify that the emulator is running and has a valid IP address
- Try reconnecting to the emulator using the `adb connect` command
Error: Screenshot Not Saved on Emulator
If the screenshot is not saved on the emulator, try the following:
- Verify that the SD card is enabled and has enough storage space
- Check the permissions and access rights for the SD card directory
- Try taking a screenshot again using a different command or options
Conclusion:
Taking a screenshot of your virtual display on an Android emulator using ADB is a quick and easy process. With these steps, you can capture high-quality screenshots for testing, debugging, or demonstrating features. Remember to enable ADB on your emulator, connect to it using the command-line interface, take the screenshot, and retrieve it from the emulator. Happy screenshotting!

How do I enable the Android emulator to take screenshots?
To enable the Android emulator to take screenshots, you need to launch the emulator from the command line using the `-screen_capture_enabled` option. For example, `emulator -avd -screen_capture_enabled`. Replace `` with the name of your AVD (Android Virtual Device).
What is the ADB command to take a screenshot of the virtual display?
The ADB command to take a screenshot of the virtual display is `adb shell screencap /sdcard/screenshot.png`. This command captures the current screen and saves it as a PNG image file named `screenshot.png` on the emulator’s SD card.

This command retrieves the screenshot from the emulator’s SD card and saves it to your computer.
Can I take a screenshot of a specific screen or activity?
Unfortunately, the ADB command `screencap` captures the entire screen, including the navigation bar and status bar. However, you can use an Android app like `screenshotER` or `Screenshot Ultimate` to capture screenshots of specific screens or activities within the emulator.
Is there a way to automate taking screenshots of the virtual display?
Yes, you can automate taking screenshots of the virtual display using scripts. For example, you can use a batch script to execute the ADB commands in sequence, or use a programming language like Python to write a script that takes screenshots at regular intervals. Get creative and automate away!
