Are you looking to streamline your app development process? Look no further! With remote debugging capabilities, you can effortlessly inspect and debug live content on your Android device from the comfort of your Windows, Mac, or Linux computer. In this tutorial, we'll guide you through setting up your Android device for remote debugging and show you how to:

  • Discover your Android device
  • Inspect and debug live content on your Android device
  • Screencast content from your Android device onto a DevTools instance on your development machine

Step 1: Discover Your Android Device

To start, follow these steps:

  • Open the Developer Options screen on your Android device.
  • Select Enable USB Debugging.
  • On your development machine, open Chrome and navigate to chrome://inspect#devices. Make sure Discover USB devices is enabled.
  • Connect your Android device directly to your development machine using a USB cable.

If this is your first time connecting your device, it will show up as "Offline" and pending authentication. Simply accept the debugging session prompt on your device's screen. If you see the model name of your Android device, DevTools has successfully established the connection to your device. Proceed to Step 2!

Troubleshooting: DevTools is not Detecting Your Android Device

If you're experiencing issues with detection, try these troubleshooting steps:

  • Ensure your hardware setup is correct:

+ If using a USB hub, try connecting your Android device directly to your development machine instead.

+ Try unplugging the USB cable and then plugging it back in while both screens are unlocked.

  • Verify your software setup:

+ If running Windows, manually install the USB drivers for your Android device. See Install OEM USB Drivers.

+ Some combinations of Windows and Android devices (especially Samsung) require extra set up. Check out Chrome DevTools Devices does not detect device when plugged in.

Step 2: Debug Content on Your Android Device from Your Development Machine

Now that you've connected your device, follow these steps:

  • Open Chrome on your Android device.
  • In chrome://inspect#devices on your development machine, you'll see your Android device's model name followed by its serial number. Below that, you can see the version of Chrome running on the device (in parentheses).
  • Enter a URL in the Open tab with url text box and click Open. The page opens in a new tab on your Android device.
  • Interact with the remote Chrome tab from this section. If there are any apps using WebView, you'll see sections for each app.

Inspect Elements

To inspect elements, follow these steps:

  • Go to the Elements panel of your DevTools instance and hover over an element to highlight it in the viewport of your Android device.
  • You can also tap an element on your Android device screen to select it in the Elements panel. Click Select Element on your DevTools instance and then tap the element on your Android device screen.

Screencast Your Android Screen

To screencast your Android screen, follow these steps:

  • Click Toggle Screencast to view the content of your Android device in your DevTools instance.
  • You can interact with the screencast in multiple ways:

+ Clicks are translated into taps, firing proper touch events on the device.

+ Keystrokes on your computer are sent to the device.

+ To simulate a pinch gesture, hold Shift while dragging.

+ To scroll, use your trackpad or mouse wheel, or fling with your mouse pointer.

Debug Manually through Android Debug Bridge (adb)

In some rare cases, an alternative method of remote debugging may be useful. For example, you may want to connect directly to the Chrome DevTools Protocol (CDP) of your Chrome on Android.

To do this, follow these steps:
