介绍一下，在下面的环境中，解决这个问题使用的解决方法。

测试环境：

Galaxy Note3 Android 5.0 
Android studio 2.2.2 
gradle-2.14.1-all 
NDK版本如下图： 

项目的build.gradle如下：

android {    compileSdkVersion 24    buildToolsVersion "24.0.3"    defaultConfig {        applicationId "com.firs.facedetecttosvr"        minSdkVersion 19        targetSdkVersion 21        ndk {            moduleName "libface_identify"            abiFilters 'armeabi', 'armeabi-v7a'        }    }   ...（部分省略）    externalNativeBuild {        ndkBuild {            path 'src/main/jni/Android.mk'        }    }}

解决方法：

第一种：

这个方法解决了我的问题，将NDK的版本换为：android-ndk-r10

ndk.dir=D\:\\Android\\ndk\\android-ndk-r10

第二种：

这个方法针对我上面的问题，没有效果，但是很多地方说到这个方法，列出以供参考：

在你报错的库libxxx.so的编译脚本Android.mk请加上：LOCAL_LDFLAGS += -fuse-ld=bfd

参考：

Issue 109071: [gold] ndk-10d defaul linker produces corrupt binaries, cannot locate symbol “__exidx_end”

NDK编译库运行时报dlopen failed: cannot locate symbol “__exidx_end” 解决办法
