How to use Chrome to debug Android webviews

Jul 30, 2025 am 12:23 AM

The core method of debugging WebView in Android development is to enable debug mode and remotely debug with Chrome DevTools. The specific steps are as follows: 1. Enable WebView debugging mode in the code, require Android 4.4 and above and add WebView.setWebContentsDebuggingEnabled(true); 2. Connect the device using USB and make sure that the developer options and USB debugging mode are enabled, and load the target WebView page; 3. Open the Chrome browser to visit chrome://inspect/#devices, click "inspect" to start DevTools; 4. Use the Elements, Console, Network and Sources panels of DevTools for debugging. If necessary, you can further control the debugging process through the adb tool. The entire configuration only needs to be set once, and the device can be automatically identified in the future, but be sure to ensure that debugging permissions are enabled in the code.

How to use Chrome to debug Android webviews

Debugging WebView is a common requirement in Android development. Fortunately, Google Chrome provides powerful remote debugging capabilities, allowing you to view and manipulate WebView content in Android applications like debugging a normal web page. With a little configuration, it can be easily achieved.

How to use Chrome to debug Android webviews

Enable WebView debugging mode

Android 4.4 (API 19) and above natively support WebView debugging function, but is turned off by default. You need to actively enable it in the application code:

  • Add the following statement to your Java or Kotlin code:
     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
      WebView.setWebContentsDebuggingEnabled(true);
    }

    Once this line of code takes effect, all the app's WebViews will be exposed to Chrome DevTools.

Note: This setting is global, and once enabled, it will affect all WebViews in the application.

Connect the device and open the target page

Make sure you have completed the following steps:

How to use Chrome to debug Android webviews
  • Connect an Android device to a computer using USB
  • Enable developer options and USB debugging mode on the device
  • Open your app and load the WebView page you want to debug

Then, open the Chrome browser on the desktop and visit chrome://inspect/#devices . You will see all debuggable WebViews running on the currently connected device.

In this page, you can see the URL or page title for each WebView. Click "inspect" to open DevTools and start debugging.

Debug WebView with Chrome DevTools

After opening the debugging interface, you will find that it is almost exactly the same as normal front-end debugging:

  • Elements panel : View and modify the DOM structure and preview style changes in real time
  • Console panel : view log output, execute JavaScript commands
  • Network panel : Monitor resource loading, including request header, response body, loading time, etc.
  • Sources panel : Set breakpoints and debug JS execution process

If your application uses multiple WebViews or has multiple pages loaded with WebViews, you can switch different contexts through the top menu.

In addition, debugging behavior can be controlled more flexibly through command-line methods, such as forwarding debug ports using adb tools or starting specific pages.


Basically that's it. Although the whole process seems to have many steps, as long as it is configured once, it will be automatically identified online. The key is to remember to enable debugging permissions in the code, otherwise you won’t even see the device list.
