How to build 64-bit Xamarin Android Application

Google announced all Android app should support 64-bit architectures from Aug 1, 2019. 64-bit CPUs deliver faster, richer experiences for your users. Google Play will continue to support 32-bit apps for now, but as of August 1, 2019 all new apps and updates that include native code must have 64-bit versions as well as 32-bit versions when publishing to Google Play. This ruling applies to apps written in native, Xamarin or apps with links to third-party native libraries.


Android application supports four ABIs that can be selected when building mobile app. You can Select which ABIs your application supports in the project android options properties, if no ABI is specified, “armeabi-v71” is used in release build and As of Xamarin.Android 9.2, armeabi is no longer supported.


  1. armeabi-v7a – ARM-based CPUs with hardware floating-point operations and multiple CPU (SMP) devices.
  2. arm64-v8a – CPUs based on the 64-bit ARMv8 architecture.
  3. x86 – CPUs that support the x86 (or IA-32) instruction set.
  4. x86_64 – CPUs that support the 64-bit x86 .
