I figured out the reason. You're using Arrays.setAll and passing in a lambda, but Arrays.setAll requires Android SDK level 24, but my app's minimum SDK version is 16.

I'm going to need you to revert your use of lambdas in the StripedKeyLockManager back to a for loop.

Actually, I notice that version 2.0.0 introduced use of Java 8 - is that change the only difference between version 1.2.0 and version 2.1.0? If so, you can probably ignore this.
