Debugging
Debug your application using either the extension or attaching to the web view. You can alternatively use Remote Logging to perform console.log
style debugging.
Debug in VS Code
Click the Debug
item to launch a web browser or attach to a running Android web view for debugging.
Click Debug
> Web
to launch a debuggable web browser such as Chrome or MS Edge. This will build your app then put VS Code into debugging mode allowing you to set breakpoints, inspect variables etc.
You can choose which browser to debug from Settings
> Advanced
> Browser
.
Attach to Web View
You can debug a running real or emulated Android Device by first running for Android by either clicking Run
> Android
or running the app in Android Studio.
Click the Debug
item and all running Android web views will appear, click one to start a debugging session for that view.
You can also attach to Web View using Chrome or Safari and use their built in debugging and inspection tools.
Use Chrome Inspect
When you have run your app from Run
> Android
or Android Studio:
- Open Google Chrome and enter into the url bar:
chrome://inspect
and press enter. - Any running web views will appear as remote targets which you can open
- Use Chrome's debugging and inspection tools.
Use Edge Inspect
When you have run your app from Run
> Android
or Android Studio:
- Open Microsoft Edge and enter into the url bar:
edge://inspect
and press enter. - Any running web views will appear as remote targets which you can open
- Use Edge's debugging and inspection tools.
Use Safari
When you have run your app from Run
> iOS
or XCode:
- Open Safari and select the iOS Device from the
Develop
menu - Use Safari's debugging and inspection tools.
You will need to turn on the development mode for Safari by going to the Safari
menu > Settings
, Advanced
and check the box Show Develop menu in menu bar
.
You'll also need to ensure your mobile device has been enabled for debugging.
Remote Logging
The remote logging feature will send all calls to console.log
(and console.error
etc) to the VS Code output
window. This makes debugging your app when it is running on a device easier as you do not have to attach to its web view.
Click Settings
> Remote Logging
to turn on the feature.
Remote logging will install a dependency @ionic/remote-log
and alter your main.ts
or index.tsx
file to start remote logging. Be sure to uncheck Remote Logging
after testing to remove this code.
