Logging & performance

[RohovDmytro]

By inspection logs I've observed a bit of logging in Android:

Does it hurt the performance in production? Should we have an option to disable it during production during animation?

Thanks for bringing this @RohovDmytro

Yeah, I've been thinking on disabling these logs by default (I added them, but I didn't receive issues where such logging would be helpful).

It shouldn't have a big impact on performance (in my case it was nanoseconds per frame, so it doesn't really matter), but spamming logcat with those logs also not a good approach.

I think the ideal solution here would be to add a custom Logger-class that disabled by default, but if you need to capture logs (for debugging purposes) then you can enable it.

What is the industry standart for such things? 👀

Aaaawesome! I will use this as an opportunity to send a huge respect for this library. It's awesome and it saved me from a nasty, nasty keyboard-management situation. Appreciate!

Speaking about perf impact I did not made any measurements, my thinking was that during animations specifically logging might have some impact.

my thinking was that during animations specifically logging might have some impact.

That also was made my assumption when I added those logs, but when measured performance then I discovered that it doesn't really affect the performance.

However I don't really like to spam logcat console and reveal details about the app (like which library it does use underhood etc.) so I think the better solution here would be to disable logger in release builds by default (and people always can enable it if needed to capture some data).

I disabled logging in release in #577

So release version should be super fast (but debug version also should be pretty fast)!
