Cavy test just launches the app

[elichai]

Hi, I'm trying to use Cavy, I followed the guide, and also tried the sample(after upgrading the gradle version there) The app launches but nothing else is happening and cavy terminates with no response after 2 minutes:

BUILD SUCCESSFUL in 23s

info Connecting to the development server...
info Starting the app on "R3CR40GSSAM"...

cavy: react-native exited with code 0.
cavy: Running Android/Sdk/platform-tools/adb reverse tcp:8082 tcp:8082
cavy: Listening on port 8082 for test results...
No response from Cavy within 2 minutes.
Terminating processes.

Tried both an emulator and a real device
