Failed to install apk when running the sample flow

[LordRaydenMK]

I was trying to run the sample maestro Flow and I got this error when executing:

maestro test android-flow.yaml

turns out, the previous step adb install sample.apk was the issue. This starts the ADB server and block DADB from connecting to the emulator.

Running adb kill-server before running the flow fixes the issue. Might be worth mentioning in the documentation.
