Error during briefcase run android, emulator failing to start.

I was following tutorial 5 and when it finished download I got the following error after running briefcase run android

I cannot manually start the emulator either. emulator-crash-service.exe tells me I am missing the following dll files: qt5coreandroidemu, qt5widgetsandroidemu, qt5guiandroidemu, which I cannot file online. Please help!

Update: It turns out this was because the Android device was set to “No data transfer”, I changed it to “File transfer / Android Auto” and it worked perfectly!

Aaargh! Sorry - that’s my fault: I copied and pasted something and didn’t check it fully. Try this instead:

import subprocess
print(subprocess.check_output(
    ["c:\users\amogh\.briefcase\tools\android_sdk\platform-tools\adb", "devices", "-l"],
    universal_newlines=True,
    stderr=subprocess.STDOUT,
).strip().split('\n'))
