代码中使用了签名验证，所以使用前请将 native-security.cpp 里的static const char *SIGN改为自己打包用的签名，签名的获取代码如下：
PackageManager pm = getPackageManager();
PackageInfo pi = pm.getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);
Signature[] signatures = pi.signatures;
Signature signature0 = signatures[0];
return signature0.toCharsString();
或是直接把 native-security.cpp 里的jint JNI_OnLoad(JavaVM *vm, void *reserved)这个方法注释掉即可。
