java.lang.UnsatisfiedLinkError: Couldn't load TestJni from loader dalvik.system.PathClassLoader[DexPathLi

解压apk后，发现确实libs中没有这个so库。

于是在build.gradle里面加上后解决问题：

android{   sourceSets {        main {            // Fixed Issue : "android studio java.lang.unsatisfiedlinkerror: couldn't load find library returned null"            // Cause : For android studio : The JNI files should be placed in the /src/main/jniLibs folder.            // Fix : Mapping the jniLibs 's source Directories with Lib's folder            jniLibs.srcDirs = ['libs']        }    }}
