The Android SDK supports the following architectures:
ARMv7, ARMv8, x86, x86_64
In other words, both the 32 and 64 bits versions of ARM and x86 are supported.
To target one or more architectures when building an App, include the following in the App's build.gradle file:
// Some other code here.
// Include one of more architectures to build for below,
// or leave out the line entirely to build for all available architectures.
// Indicate whether to build a universal APK, which targets all available architectures.
