Ionic VScode extension Gradle build fails

When Starting a new project and following the tutorial steps for the VScode extension:
Ionic>New Vue Project>tabs(as an example)>my-app
then
Ionic>Recommendations>Add Ionic CLI
Ionic>Recommendations>Add Android Project

at this point i’d wish to run my app on an emulator to see what I have…
I’ve been doing
Ionic>Capacitator>build
Ionic>Capacitator>Sync

Then
Ionic>Run>Android
I choose the emulator (Pixel 2 API 28)

and I get this error

which is resolved by running $ ionic cap build
waiting for android studio to build the gradle, then I can close android studio and
Ionic>Run>Android
by just clicking on it

is this a necessary step and you have to open Android Studio everytime you want to build the gradle?
is my execution order not right ?

Thanks

Unfortunately, programmatically building the native project is not yet supported.
