Call requires API level 19 (current min is 16): java.util.Objects#requireNonNull

[vanniktech]

After updating from 'me.tatarka:gradle-retrolambda:3.2.5' to 'me.tatarka:gradle-retrolambda:3.4.0' lint complains:

Call requires API level 19 (current min is 16): java.util.Objects#requireNonNull

Still happening with 3.6.0.

Hello, I'm having the same issue on 3.6.0 version also, lint is failing because of it.

@vanniktech Are you still using 3.2.5 or have found any workaround? I receive the same lint error after including error-prone into project.

[vanniktech]

Moved on to Kotlin and the projects that are still having Lambdas are now all minSdk 19.

I don't have this problem. minSdk = 15, gradle-retrolambda 3.6.0, Android Studio 2.3.3
Solution is waiting release of Android Studio 3.0, there are build-in support of Java 8 features in it

[MyDogTom]

I've found that in my case issue is not related to Retrolambda. java.util.Objects#requireNonNull is added automatically by ErrorProne compiler. In order to change this behavior, just add -XDallowBetterNullChecks=false
More details here: google/error-prone#375

Oh that might be the case since I'm using error prone. Guess this can be closed then.
