React Native version: 0.37.
Platform: Android
Operating System: Android M +
          
When I run app (using 'react-native run-android' command) at 64-bit smartphone it worked fine, but release version apk crashed instantly, while same apk also working fine at 32-bit smartphone
RcaHandler: Build: Sony/E5603/E5603:6.0/30.2.A.0.100/167960284:user/release-keys

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

RcaHandler: 	at java.lang.Runtime.load(Runtime.java:332)

RcaHandler: 	at java.lang.System.load(System.java:1069)
Running RN 0.43.3. Worked fine on my Nexus 6, doesn't work on my Pixel. Both are on Android 7.1.2.
I can run the app if I add this to my build.gradle file, but then other things seem to break in my React views.
packagingOptions {
    exclude '/lib/mips64/**'
    exclude '/lib/arm64-v8a/**'
    exclude '/lib/x86_64/**'

+1, same error on API 23 device when using 0.44.2 with existing app integration.

After adding following seems working:
locating the gradle.properties file in the root project, and add Android.useDeprecatedNdk=true.
in the build.gradle of the app:
android {  
    defaultConfig {  
        ndk {  
            abiFilters "armeabi-v7a", "x86"  
        packagingOptions {  
            exclude "lib/arm64-v8a/librealm-jni.so"  
In this way, using 32bit so instead of 64 bit, still, hope there's an official solution.
  guess, yogieputra8, bdbergeron, BALUSANGEM, ggsrivas, JeffMcKnight, hiddentao, Rowandjj, mistarA, matoso, and smbteam1 reacted with thumbs up emoji
  with0out, hiddentao, and chug2k reacted with hooray emoji
      All reactions
          
@BALUSANGEM the reason why should config certain ndk abiFilters is that this is configured in the mk  file—— check out  your react native project directory\node_modules\react-native\ReactAndroid\src\main\jni\Application.mk：
As for the impact, some 3rd party libraries may only provide armeabi instead of "armeabi-v7a", "x86". So in my opinion, there is a risk of app crash.
          
I have the same problem，I must add   'armeabi', 'arm64-v8a'   to  ndk，

ndk {

abiFilters "armeabi-v7a", "x86", 'armeabi', 'arm64-v8a'

How to solve it?
and it doesn't work but If I use those:
        exclude 'lib/armeabi-v7a/libgnustl_shared.so'
        exclude 'lib/x86/libgnustl_shared.so'
I'm able to build application and run. But I get explicitly error:
 java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[........] couldn't find "libgnustl_shared.so"
 at java.lang.Runtime.loadLibrary0(Runtime.java:984)
 at java.lang.System.loadLibrary(System.java:1530)
[Edit]
That helps me:
