Constant rpctimeout errors after upgrading to Unity 2019

[fabioramos8]

Describe the bug "RpcTimeoutError" and "socket connection broken" were errors that happened from time to time but since it was very occasionally, I didn't search for a fix. However, after upgrading my project to Unity 2019, these became a lot more frequent to the point where I am unable to run a 10min test without it breaking due to a "RpcTimeoutError."

Example below:

Ran 1 test in 589.428s

FAILED (errors=1)

python version: python2.7.15 (but I tried with different ones)

poco version: 1.0.76

Smartphone:

• Device: pocophone f1, motog6 plus, oneplus6
• OS: Android 9, Android 8, Android 9

Additional context I reckon these connectivity issues might have been introduced by the new Unity but I still took the liberty to submit an issue here in hopes that someone has insight about this kind of errors. Overall, Airtest and the poco integration work really well, you guys did a great job -- it's only these connectivity issues that are disabling me to use your software in its full capacity.

hi @fabioramos8 what's the log in logcat when the RpcTimeoutError occurs?

[fabioramos8]

unfortunately, there are no relevant logs on logcat regardless of the filtering that I set -- the script simply dies silently

ret, err = cb.wait(timeout=30)

It seems that the issue is that if the hierarchy is not visible in 30 seconds, it raises the exception of Rcptimeouterror

method can be found in "/usr/local/lib/python3.6/dist-packages/poco/utils/simplerpc/utils.py"

This can be a common issue if you have huge hierarchy node that takes very long time to refresh/appear, or at the beginning of the application when trying to load it first time, which might be because you are trying to use poco too soon
