Error while starting instrumentation with Obfuscated apk (with proguard)

Details
Espresso server has gson as dependancy. In many cases gson is a dependancy of the app under test as well. When the app is obfuscated, Its complains NoSuchMethodError for obfuscated methods as below:

[dpgraham]

So the app gets obfuscated but espresso-server doesn't, and that still happens?

[rajdeepv]

Yes, App under test is obfuscated but Espresso server is not.
If I build unobfuscated app, I do not get above error.

[dpgraham]

I'm going to look at this.... @mykola-mokhnach do you have any ideas, off the top of your head, why this would be happening?

[rajdeepv]

@dpgraham I have found a way to avoid this. In the application code, we need to make sure that we don't obfuscate com.google.gson

Thanks!

[dpgraham]

Okay good to know @rajdeepv! We'll still keep it open though. For other users who have this same problem we'll need to either come up with a solution or list it as a "Known Issue" and provide a recommended workaround.

Maybe, this is also a similar issue. I would leave the log here.
