出错的代码为：

JPushInterface.setDebugMode(true);
<span style="color:#ff0000;"> JPushInterface.init(this);</span>

后来搜素了极光帮助文档Java.lang.UnsatisfiedLinkError后，发现问题在于libs/armeabi/
.so文件，一看原代码果然没有添加。
于是便下载了最新版jpush-sdk-release1.6.1的sdk，拷贝libjpush.so放入，重刷之后还是报错，我就纳闷了。

紧接着上了极光问答的社区，搜索了这个问题，发现解决方法还是一样，问题是 .so文件不一样了，libsys.so文件也有，libpushp**.so之类的文件也有，这才意识到版本不同，对应的.so文件也不一样。

最后，拷贝了新的jpush-sdk-release1.6.1.jar替代了原来的jpush-sdk-release1.5.5.jar，再刷一次，程序终于不报错了

所以结论就是，原因是.so不在正确的位置(libs–>armeabi–>.so)，且要jar包和.so文件要对应，只要拷贝好正确的文件和位置，就没问题了
