Unity Android - Cant Build for x86_64 architecture

Question

I am trying to get a 64-bit build to comply with google play but whenever I "Analyse" my apk in android studio "x86_64"never seems to show up as a dependency under the "lib" folder.

Some details / things I've tried:

• Unity 2018.4.2f1 with gradle 3.2.0
• I am using "IL2CPP" as the scripting backend with ARM64 selected
• In the "defaultConfig" of my maintemplate.gradle I have manually specified the different archetectures with ndk { abiFilters "armeabi-v7a", "arm64-v8a", "x86", "x86_64" }

Answer 1

According to the x64 integration docs,

If you see armeabi-v7a or x86, then you have 32-bit libraries. If you do not have any arm64-v8a or x86_64 libraries, you'll need to update your build process https://developer.android.com/distribute/best-practices/develop/64-bit

Unity3d Blog:

While we added support for Android ARM 64-bit, we also reviewed the usage of Android x86. Limited x86 Android devices were introduced to the market which has resulted in minimal adoption of Unity’s x86 Android support. Android x86 support will be deprecated in 2019.2 and removed entirely in Unity 2019.3. Support for Android x86 will continue in Unity 2018 and 2018 LTS for the remainder of their life cycle. https://blogs.unity3d.com/ru/2019/03/05/android-support-update-64-bit-and-app-bundles-backported-to-2017-4-lts/
