@matteinn You can use 4.2.1-SNAPSHOT now or wait for the next patch release which should be coming out soon. This is the safeMode API.

From what I see in https://github.com/airbnb/lottie-android/pull/1939 it looks like no changes will be required on consumer apps, besides upgrading to the next SDK version which will contain that PR
