Trigger program on host with Espresso

[Jochen Weiss]

Hello,

I don't know if this is the correct forum for my question, but I did not find another one.

I'm writing some tests using Googles Espresso framework. Here I need to test some speech recognition.

To do so, I need to start an audio file at certain point on the host PC and check if the target device recognize the command correct (simply connected host audio out --> target audio in).

Is there a way to trigger an execution on the host during an Espresso test (which runs on the target)?

If not Espresso support this, maybe adb does ????

Thanks for any idea how to handle this.
