How can I get console.log output from my mobile ON the mobile device?

Question

I do a lot of my dev work from mobile devices. Is there a way to get js access to console.log output from within a mobile browser?

Answer 1

For Android - I found this works:

1. Open Android Studio IDE
2. Connecting the device in debug mode
3. Open logcat
4. Run the browser UI on android device - to see the console log output

Here's a few console.log() lines from logcat:

[INFO:CONSOLE(18)] "100 - checking FUNC PARAM ... ", source: https://somewhere/util/message_util.js (18)

[INFO:CONSOLE(18)] "101 - > ENTER: AppAuth.onHasAuthFunc", source: https://somewhere/util/message_util.js (18)

Idea to try this approach, thanks to @Marcus's answer , suggesting:

" 'hook into' the native console "

Also, saw other posts suggesting to type: about:debug

.. into the address bar of device browser. Not sure if that had anything to do with getting the connection to work
