React native expection java.lang.UnsatisfiedLinkError: dlopen failed: "/data/data/{package}/lib-main/libgnustl_shared.so" is 32-bit instead of 64-bit

Question

I am trying to integrate React Native with my existing Android App. I am getting the following exception, when initilizing React Native Screen:

java.lang.UnsatisfiedLinkError: dlopen failed: "/data/data/com.snapdeal.main/lib-main/libgnustl_shared.so" is 32-bit instead of 64-bit

The App is only crashing on 64-bit devices.

As per my learning so far, I've found this issue reported on React Native Repo, but the solution suggested in this thread is not helpful as I am not using any external SO library in existing App.

Apart from above, I've realized another difference in library structure on the device where my App is installed. I am comparing structure of my App vs react native demo app.

React demo App

root@generic_x86_64:**/data/data/com.react.demo/lib** # ls
libfb.so
libfolly_json.so
libglog.so
libglog_init.so
libgnustl_shared.so
libicu_common.so
libimagepipeline.so
libjsc.so
libreactnativejni.so
libreactnativejnifb.so

root@generic_x86_64:/data/data/**com.react.demo**/lib-main # ls
dso_deps
dso_lock
dso_manifest
dso_state

My App

root@generic_x86_64:/data/data/**com.my.app**/lib-main # ls
dso_deps
dso_lock
dso_manifest
dso_state
libfb.so
libfolly_json.so
libglog.so
libglog_init.so
libgnustl_shared.so
libicu_common.so
libimagepipeline.so
libjsc.so
libreactnativejni.so
libreactnativejnifb.so

Any clue is appreciated.

PS: I know react-native does support 64-bit binaries and I am not using any external library.

Add the following into app/gradle file

defaultConfig {
....

    ndk {
        abiFilters "armeabi-v7a", "x86", 'armeabi', 'arm64-v8a'
    }

    packagingOptions {
        exclude "lib/arm64-v8a/libgnustl_shared.so"
    }
}

also make sure you working with the same port.
