FvpPlugin: static initializer: loadLibrary fvp_plugin error: java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "_ZNSt6__ndk122__libcpp_verbose_abortEPKcz"

Describe the bug

使用 flutter create -t module my_flutter指令创建一个flutter module，添加了fvp插件，开发完成后，使用
dependencies {
debugImplementation
'com.example.flutter_module:flutter_debug:1.0'
profileImplementation
'com.example.flutter_module:flutter_profile:1.0'
releaseImplementation
'com.example.flutter_module:flutter_release:1.0'
}
添加到现有的原生Android项目中，项目能正常运行，但是打开播放器时，提示：
W FvpPlugin: static initializer: loadLibrary fvp_plugin error: java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "_ZNSt6__ndk122__libcpp_verbose_abortEPKcz" referenced by "/data/app/~~TRCjrQeEUfjy8xmfDeH5yA==/com.tech.module-_Pjup2dJiB5DKjFCDDNj9w==/lib/arm64/libfvp_plugin.so"...
播放失败，这是什么原因；

Expected behavior

项目能正常运行，正常播放视频

Log

Add

import 'package:fvp/fvp.dart' as fvp;

add the following lines before registerWith()

 fvp.registerWith(
    options: {
      'platforms': ['ios', 'android'],
      'video.decoders': ['FFmpeg'], // FFmpeg、AMediaCodec、MediaCodec
      'lowLatency':
          1, // 减少延时，这里有说明：https://github.com/wang-bin/mdk-sdk/issues/347
    },

因为编译libfvp_plugin.so的libc++版本高，打包的libc++版本低于17。一个办法是打包用到的最新的libc++或者统一版本，另一个办法是引入兼容代码 https://github.com/wang-bin/cppcompat/blob/master/src/libcxx_verbose_abort.cpp

[Koenger]

libc++ 版本相同了，但是提示了Unhandled Exception: Invalid argument(s): Failed to load dynamic library 'libfvp_plugin.so': dlopen failed: cannot locate symbol "_ZNSt6__ndk122__libcpp_verbose_abortEPKcz" referenced by "/data/app/~~7_69Ba6JxMnRAGtmH9-z1w==/com.tech.module-u4MBB0uoa5F-R79ELC5jww==/lib/arm64/libfvp_plugin.so"...

Issue Explanation

Error: libfvp_plugin.so fails to load because it references __libcpp_verbose_abort, a symbol that doesn't exist in the libc++ runtime bundled in the APK.

Root Cause — C++ ABI mismatch across NDK versions

The symbol _ZNSt6__ndk122__libcpp_verbose_abortEPKcz (demangled: std::__ndk1::__libcpp_verbose_abort(char const*, ...)) was introduced in NDK r26+'s libc++. The fvp plugin compiles against this newer libc++ (the prebuilt mdk-sdk-android.7z is built with it), but the consuming Android app ships an older version of libc++_shared.so — likely from an older NDK or a dependency that bundles a stale copy.

Since the project uses c++_shared STL (android/build.gradle:63), all native libraries share a single libc++_shared.so. If any library in the APK drags in an older copy, the linker resolves to that older copy, and __libcpp_verbose_abort is missing → dlopen fails.

The Maintainer's Recommended Fixes

1. Unify libc++ version — ensure every native library in the APK uses the same NDK version and that the newest libc++_shared.so wins. In the consumer app's build.gradle:

   android {
       packagingOptions {
           pickFirst '**/libc++_shared.so'
       }
   }

2. Add a compatibility shim — compile libcxx_verbose_abort.cpp into libfvp_plugin.so as a stub. This provides a no-op definition of the symbol so the linker doesn't need it from libc++. This is the lower-friction fix for end users who can't control all native dependencies in their app.
