+# Retrofit consumer rules are not sufficient for R8 full mode.
+# Since Retrofit is delivered with mapbox-java and mapbox-java is not an Android library,
+# therefore it can't include consumer proguard rules, we include them here, as this module uses mapbox-java as a transitive dependency
+# and this is the base module for all other modules in the NavSDK.
+# Rules are copied from https://github.com/square/retrofit/blob/trunk/retrofit/src/main/resources/META-INF/proguard/retrofit2.pro.
