so库报错：
java.lang.UnsatisfiedLinkError: No implementation found for long jssc.SerialNativeInterface.openPort(java.lang.String, boolean) (tried Java_jssc_SerialNativeInterface_openPort and Java_jssc_SerialNativeInterface_openPort__Ljava_lang_String_2Z)

解决：1、查找app安装内lib已存在该so库
2、发现原来没有把so库load进来
System.loadLibrary("jssc");
