I encountered the same issue and haven't found the root cause yet. My guess is that Quasar might not have successfully created the service in Capacitor mode. However, you can achieve the desired functionality indirectly using the following steps:

1.Start the app service with a specified port(same port as the second command)
quasar dev -p 9000 -m capacitor -T android
2.Start another service
In a new command line window, run the default development service (default port 9000):
quasar dev
This way, the app in Android Studio will be able to run and support hot reload.

Cannot reproduce.
Can you guys share more info on your setup? What OS are you using (and version). Also, what Android Studio are you on etc etc.

Hello,
I got the same problem with a real android device. The dev server starts on spa but not with capacitor-android.
I was able to make it work again by downgrading to V0.15 launching quasar dev then re-upgrading to current version.
The commands are:
npm i -g [email protected]
quasar dev -m capacitor -T android
npm i -g quasar-cli

I have no explanation why it stopped working, then why it started working again :(

My config:

• Android studio 2024.2.1
• @quasar/app-vite 2.0.5 (@quasar/cli 2.4.1)
• quasar-cli 0.17.26
• Linux ubuntu 22.04.5 LTS

EDIT 01/07 In fact, this does not work. The dev server does not start

I've run into the same issue:

It appears to me as if the dev server doesn't start. The first output is the result of running curl on my machines local ip address after I started up quasar dev. The second and third are while quasar dev -m capacitor -T android is running.

EDIT: What I want to show with the last picture: The server is up and running after calling quasar dev, but appears to not be up and running after calling quasar dev -m capacitor -T android.

npx quasar --version gives me @quasar/app-vite 2.0.5. Please tell me any further information I can provide to help fixing this issue.

I have the same problem after upgrading to @quasar/app-vite@2.

• quasar dev command works fine
• quasar dev -m capacitor -T android doesn't throw any errors or warnings, appears to set up the android project fine but the dev server can't be connected to (ERR_CONNECTION_REFUSED). This includes manually going to the generated dev server url so doesn't appear to be anything to do with android studio or the android project directly.

EDIT: This comment originally had information about reproducing the error with a brand new quasar app but after rebooting my machine the dev server for the new quasar app now works correctly. Unfortunately my app is still broken with the same error.
