华为手机输出的错误log：

小米手机输出的错误log：

最初使用的是小米手机进行调试的，一直显示需要依赖 libnativeloader.so，google了一圈 未找到有用信息，被小米的log误导了，以为是androidX 的兼容问题，修改了targetSdkVersion等都无效，换到华为手机后明显提示libmp3lame.so的so库加载不到，在 library 的 build.gradle 的 android {} 声明了如下两个加载so的目录后仍然无效：

sourceSets{
    main {
       jniLibs.srcDirs = ['libs']
    }
}

repositories{
        flatDir {
            dirs 'libs'
        }
}

重新梳理了一遍代码 才想起来我只编译生成了 armeabi-v7a 下的so文件，因为该架构下的so库足以兼容市面上的大部分手机，到这里基本就猜测的到，新建的demo工程没有指定apk支持的so abiFilters，添加abiFilters编译通过

ndk {
    //设置支持的SO库架构
    abiFilters 'armeabi', 'armeabi-v7a'//, 'arm64-v8a'//, 'x86_64',
}
