I'm unable to inspect Webview with the Android SDK

Sometimes when you're Android app is running and you want to inspect the webview for debugging/reproduction purposes, you don't see the inspect button that is usually there.

It does however detect the device and it's webview, as seen below.

no inspect button

Solution

This is likely a problem caused by the Android version being quite old (4.4.4 and older).

Where you would normally write WebView.setWebContentsDebuggingEnabled(true); to enable webview inspecting, older versions require you to add the following snippet:

...
import org.xwalk.core.XWalkCookieManager;
import org.xwalk.core.XWalkPreferences;
import org.xwalk.core.XWalkResourceClient;
import org.xwalk.core.XWalkSettings;
import org.xwalk.core.XWalkUIClient;
import org.xwalk.core.XWalkView;
import org.xwalk.core.XWalkWebResourceRequest;
import org.xwalk.core.XWalkWebResourceResponse;
 
public class MainActivity extends AppCompatActivity {
 
...
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        // This line is used for newer Android versions instead of the XWalk bits
        // WebView.setWebContentsDebuggingEnabled(true);
 
        XWalkPreferences.setValue(XWalkPreferences.REMOTE_DEBUGGING, true);
        ...
 
...

The lines including "XWalk" are the ones that need to be added for older Android versions (< 5.0.0).

Your webview should now be inspectable through Chrome developer tools.
