Scanning code on Android can be a useful skill to have, especially if you are a developer or someone who frequently works with QR codes or barcodes. In this tutorial, we will explore different methods to scan code on Android devices.

Using the Camera App

If you have a modern Android device, chances are it comes with a built-in camera app that supports code scanning. Here’s how you can use it:

  1. Open the Camera App: Locate and open the camera app on your Android device. The icon usually resembles a camera or can be found in the applications menu.
  2. Access the Code Scanner: Once the camera app is open, look for an option that allows you to scan codes. This option may vary depending on your device and camera app version. It may be labeled as “Scan QR Code” or “Scan Barcode.

  3. Aim at the Code: Point your Android device’s camera at the code you want to scan. Make sure the entire code is within the frame of your camera viewfinder.
  4. Wait for Recognition: The camera app will automatically recognize and decode the code. It may take a few seconds for it to process and display the information contained in the code.


In some cases, you might need to tap on the screen to focus before scanning. Additionally, if there are multiple codes in view, make sure to align your device’s camera with only one code at a time for accurate scanning.

Using Third-Party Apps

If your Android device’s default camera app does not support scanning codes or if you prefer more advanced features, there are several third-party apps available on the Google Play Store. Here’s how you can use one of these apps:

  1. Open the Google Play Store: Locate and open the Google Play Store app on your Android device. The icon usually resembles a shopping bag with a colorful triangle.
  2. Search for Code Scanner Apps: In the search bar at the top of the screen, type in “code scanner” or “QR code scanner” to browse through the available options. Popular choices include “Barcode Scanner” and “QR & Barcode Scanner. “
  3. Select and Install an App: Choose an app that suits your needs and preferences, then tap on it to view more details.

    Once you have made your decision, click on the “Install” button to download and install the app onto your device.

  4. Open the Code Scanner App: Locate and open the code scanner app you installed from the Google Play Store. The app’s icon will now appear in your device’s applications menu or home screen.
  5. Scan a Code: Follow the instructions provided by the code scanner app to scan codes using its interface. This might involve aiming your camera at a code, tapping a button to initiate scanning, or adjusting settings according to your preferences.

Troubleshooting Tips

If you encounter any issues while scanning codes on Android, here are some troubleshooting tips that might help:

  • Check Camera Permissions: Ensure that you have granted camera permissions to both your default camera app and any third-party code scanner apps you are using. You can do this by going to Settings > Apps > [App Name] > Permissions.
  • Update Your Apps: Make sure your camera app and any third-party code scanner apps are up to date.

    Developers often release updates to improve performance and fix bugs.

  • Clean the Camera Lens: Sometimes, a dirty camera lens can interfere with scanning. Use a microfiber cloth or lens cleaning solution to clean your device’s camera lens.
  • Troubleshoot Network Issues: If you are scanning codes that require an internet connection, ensure that your device is connected to a stable network.


Scanning code on Android devices is a straightforward process that can be done using the built-in camera app or third-party apps available on the Google Play Store. Whether you are scanning QR codes for website links or barcodes for product information, having this skill can save you time and effort. Just remember to follow the instructions provided by the app you choose and make sure your device’s camera is in focus for accurate scanning.
