Vungle Android SDK supports the 64-bit requirement. Vungle Android SDK doesn't use any native code like c,c++ and is written entirely in non-native code. So we are supporting 64 bit already.
64-bit CPUs deliver faster, richer experiences for your users. Adding a 64-bit version of your app provides performance improvements, makes way for future innovation, and sets you up for devices with 64-bit only hardware. Starting August 1, 2019, all the apps that use native code must provide a 64-bit version on GooglePlay. Here is the link where you can find more details about 64-bit requirement and expectations from Google.
