Welcome - Texas, and behar
I made today on this apk 500 km - and for my taste, except that operates in ART mode - there is no change.
And as for the fact that the apk has a different size ...... - God knows why, because declarations of ART until such a large change should not give (perhaps a way of packaging - I have no clue - it's important that it works).
Maybe he knows something Tichij colleague - and will want to answer?
