ava.lang.UnsatisfiedLinkError: Couldn't load XXXfrom loader dalvik.system.PathClassLoader[DexPathLis

android studio导入so包异常：java.lang.UnsatisfiedLinkError: Couldn’t load sm2 from loader dalvik.system.PathClassLoader[DexPathList[[zip file”data/app/com.libCom.androidsm2-.apk”],nativeLibraryDirectories=[/data/app-lib/com.libCom.androidsm2-2, /vendor/lib, /system/lib]]]:
findLibrary returned null 

原因：android studio导入so文件没有编译到apk里面去，所以导致UnsatisfiedLinkError异常

解决办法: 

1、AS工程（module）目录下直接新建一个lib文件夹，lib文件夹跟Eclipse类似的加入armeabi文件夹，所有的so文件放入此文件夹下 

2、打开build.gradle，在android的标签下加入如下代码：

<code class="hljs bash has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">  <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">source</span>Sets {
main {
//jni库的调用会到资源文件夹下libs里面找so文件
jniLibs.srcDirs = [<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'libs'</span>]
}
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>

代码很简单，加入之后直接编译就OK啦
