1947512 - `./mach run --debug` doesn't work if Android Studio is running

Status: NEW

(Firefox Build System :: Android Studio and Gradle Integration, defect)

Description

[Ted Campbell [:tcampbell]]

I don't have a good fix here yet, but I wanted to document this footgun.

STR

• Start Android Studio for device screen mirroring
• Run ./mach run --debug

Expected

• App starts and debugger attaches

Actual

• App hangs waiting for a debugger

The issue is that when Android Studio is running, they have a background adb track-jdwp process which monitors for JDWP debug sessions on the device and captures them inside Android Studio. The result is that the "jdb ping" logic of ./mach run --debug hangs forever trying to connect to the app.

The simple work-around is to close Android Studio, but it might be nice at the very least for ./mach run --debug to detect Android Studio is running in background and give a warning..
