React native has been released the new version of the react native on 12 march. In this new version react native support the 64 bit systems. You can read more detail about this on below link. http://facebook.github.io/react-native/blog/2019/03/12/releasing-react-native-059

Answer 2

react-native new versions support 64 bit automatically. just update react-native version to 0.59.0 or after and rebuild your application, just run:

react-native upgrade 0.59.1

Answer 4

If you are using react native version less than 0.59 then you must upgrade your apps to react native 0.59 or higher. React native supports 64 bit only from 0.59 version.

Also, make sure your app has following lines in your MyProject/Android/App/Build.gradle file.

splits {
        abi {
            reset()
            enable enableSeparateBuildPerCPUArchitecture
            universalApk true  // If true, also generate a universal APK
            include "armeabi-v7a", "x86", "arm64-v8a", "x86_64"
        }
    }

Facebook seems to be dragging their feet on supporting 64 bit builds.

You can check the intermediates in the build folder to see what abis you are supporting.

https://developer.android.com/ndk/guides/abis.html

Android takes the lowest common denominator of build abi. This is going to become an issue if Facebook doesn't address it soon.

Answer 6

All of the native code for an app is stored in the libs/ directory in the root of the apk. eg for compiled ARM or x86 code, you can find it in libs/architecture_type/lib_name.so.

An APK is essentially just a zip file so you can extract it with any zip tool.

The list of architectures (ABIs) is here. If you don't have directories for arm64-v8a or have x86 but don't have x86_64 then you are missing the 64 bit native code.
