@joaopiopedreira, @marc.weeber,
This thread helped me out: Android Standalone build failed - #18 by rmaniar
I updated the lottie dependency from 2.5.+ to 2.5.5 in android/app/build.gradle and also updated its version references in the following:
android/maven/host/exp/exponent/expoview/28.0.0/expoview-28.0.0.pom
android/maven/host/exp/exponent/expoview/28.0.0/ivy-28.0.0.xml
Those updates along with a rebuild got the project running again, good luck!
