1、在做一个人脸识别的项目，使用的是讯飞的api，编辑器为AS2.0，运行时报如下错误：

 FATAL EXCEPTION: main
                  Process: com.admin.smartcam, PID: 13821
                  java.lang.UnsatisfiedLinkError: Native method not found: com.faceplusplus.api.Native.setMinFaceSize:(II)I

                      at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:602)
                      at dalvik.system.NativeStart.main(Native Method)

2、分析【可能是因为系统找不到我的.so文件】

工程目录如下：

3、解决办法：

打开build.gradle文件添加如下代码：

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

至此就ok了！

android 使用讯飞人脸识别api报错：java.lang.UnsatisfiedLinkError
