App build has warning issues "Unable to strip the following libraries"

[leonidlewis]

Description

When I build the simple app only shows "Hello world", I've got the following warning, and the size of my app reaches 32MB. I used the build command ./gradlew assembleRelease and also used Android Studio. I got the same warning in both cases. Android Studio has installed the NDK(side by side) to strip these packages. How can I fix this issue?

> Task :app:stripDebugDebugSymbols
Unable to strip the following libraries, packaging them as 
they are: libbetter.so, libc++_shared.so, libevent-2.1.so,

Version

Steps to reproduce

I created the app with this command. npx react-native init sample I installed react-native-geolocation-service. I build the app with ./gradlew assembleRelease But I've got a warning.

Hi, I have that warning too, and I am uncertain if I should be worried or not. I gives that warning on a the initial app with nothing else in it - just:

npx react-native init Test cd Test npx react-native run-android

Works fast and opens the app but gives that warning:

If you are using Gradle build tools version 4 or higher, adding android:extractNativeLibs="true" to application as per android documentation, may solve the issue.

@thejadasari This will not resolve the "Unable to strip the libraries error". This will help to reduce the build apk size.

I'm on an existing app and I have the same issue when I migrated from react-native 0.64 to 0.67.3.

Unable to strip the following libraries, packaging them as they are: libbetter.so, libc++_shared.so, libconceal.so, libevent-2.1.so, libevent_core-2.1.so, libevent_extra-2.1.so, libfabricjni.so, libfb.so, libfbjni.so, libflipper.so, libfolly_futures.so, libfolly_json.so, libglog.so, libglog_init.so, libhermes-executor-common-debug.so, libhermes-executor-debug.so, libhermes-inspector.so, libhermes.so, libimagepipeline.so, libjsi.so, libjsijniprofiler.so, libjsinspector.so, liblogger.so, libmapbufferjni.so, libnative-filters.so, libnative-imagetranscoder.so, libreact_codegen_rncore.so, libreact_debug.so, libreact_nativemodule_core.so, libreact_render_animations.so, libreact_render_attributedstring.so, libreact_render_componentregistry.so, libreact_render_core.so, libreact_render_debug.so, libreact_render_graphics.so, libreact_render_imagemanager.so, libreact_render_leakchecker.so, libreact_render_mapbuffer.so, libreact_render_mounting.so, libreact_render_runtimescheduler.so, libreact_render_scheduler.so, libreact_render_telemetry.so, libreact_render_templateprocessor.so, libreact_render_textlayoutmanager.so, libreact_render_uimanager.so, libreact_utils.so, libreactconfig.so, libreactnativeblob.so, libreactnativejni.so, libreactnativeutilsjni.so, libreactperfloggerjni.so, libreanimated.so, librrc_image.so, librrc_modal.so, librrc_progressbar.so, librrc_root.so, librrc_scrollview.so, librrc_slider.so, librrc_switch.so, librrc_text.so, librrc_textinput.so, librrc_unimplementedview.so, librrc_view.so, libturbomodulejsijni.so, libyoga.so.

In addition, I'm trying to migrate to hermes engine (following: https://reactnative.dev/docs/hermes) and the const isHermes = () => !!global.HermesInternal return false.

I guess it's related to libhermes-executor-common-debug.so, libhermes-executor-debug.so, libhermes-inspector.so, libhermes.so.

Same predicament, been struggling mightily with this for a week. Our libs would not be stripped and caused an oversized base.zip file in our build files (800 mb!), which causes node to choke.

What has mostly helped is adding the ndk.dir property to local.properties and pointing it to ndk-bundle directory. Although you will see deprecation (of ndk.dir) warnings, that resolved this mostly; we still have one library that isn't stripped (libconceal.so).

[clytras]

The NDK version set by ndkVersion inside android/build.gradle must be installed using Android Studio SDK Tools.

1. Check the ndkVersion inside android/build.gradle

   buildscript {
   ext {
       buildToolsVersion = "31.0.0"
       minSdkVersion = 21
       compileSdkVersion = 31
       targetSdkVersion = 31
   
       if (System.properties['os.arch'] == "aarch64") {
           // For M1 Users we need to use the NDK 24 which added support for aarch64
           ndkVersion = "24.0.8215888"
       } else {
           // Otherwise we default to the side-by-side NDK version from AGP.
           ndkVersion = "21.4.7075529"
       }
   }
   }

2. Open Android Studio 🡪 Settings 🡪 Android SDK 🡪 SDK Tools, check the "Show Package Details" at bottom right and then under NDK (Side by side) check the exact version to match the one inside android/build.gradle and then hit the Apply button.

Wait to finish installing and then clean the app with something like cd android && ./gradlew clean && cd .. and then rebuild it.

This fixed this issue for me and there are no "Unable to strip the following libraries" errors any more after clean builds.

I'm still getting this issue after after following the NDK steps I'm using M1 device do I have to add any NDK path or any thing else ?

[chirag-codealchemy]

libbetter.so, libc++_shared.so, libconceal.so, libevent-2.1.so, libevent_core-2.1.so, libevent_extra-2.1.so, libfabricjni.so, libfb.so, libfbjni.so, libflipper.so, libfolly_futures.so, libfolly_json.so, libglog.so, libglog_init.so, libhermes-executor-common-debug

add this to your app build gradle

android {
    packagingOptions {
        pickFirst 'lib/*/*.so'
    }
}

[shakibhasan09]

Same issue here

[iTheDaybreak]

用命令--info 查看原因，一般是ndkVersion 不匹配，strip tools找不到 bash gradlew assembleRelease --info

Closing as extremely old issue. The NDK integration of RN has been completely rewritten as of 0.71 so this issue is definitely not relevant anymore

@cortinico As you can see, closing an issue saying that it's old and now not relevant does not magically solve the problem. Please consider reopening this issue.

Like people don't have anything better to do and they just come back to issues and recreate them. No, I will not create an issue that was existing not resolved and closed blindly. If you don't care why should I.

I have met this issue, but found the Android Emulator API was not correct. Then changed the version, it could be fine. Maybe this can help someone.
