Cap run android starts web version

After adding native code, my app can no longer run in the browser.

(which is not a bad thing. I mean, running the native code in the browser simply isn’t possible.
And debugging with chrome inspector works like a charm :slight_smile: )

But starting the IDE with:

ionic cap run android -l --external

always opens both Android Studio AND the web browser.
It says:

react-scripts start
[INFO] Browser window opened to http://localhost:8100!
capacitor open android

Can I prevent this somehow?
The browser preview is useless without the custom code. I would prefer if cap run android really only started android.
