JNI将无符号字符*转换为jbyteArray，并将jbyteArray返回到java

我使用c获得了一个无符号的char*数据，该数据由AES递减，我想将该数据转换为jbytearyay并返回到java： 代码如下：

{
   unsigned char* token = get_token();//get token from AES decrypt method

   LOGV("token is:%s",token);//it shows me that string like:"jghgillldjdmdejkgmmjdkf"

   /**
    * when i try this line:unsigned char* token = "jghgillldjdmdejkgmmjdkf";i works.
    */

   jclass strClass = (*env)->FindClass(env,"java/lang/String");
   jmethodID ctorID = (*env)->GetMethodID(env,strClass,"<init>", "([BLjava/lang/String;)V");
   jbyteArray bytes = (*env)->NewByteArray(env,strlen(token));
   (*env)->SetByteArrayRegion(env,bytes,0,strlen(token),(jbyte*)token);
   return bytes;
}

但是android设备崩溃了，错误日志是：

如果打印

strlen（令牌）

会得到什么？什么是“无”-空字节数组还是空字节数组？有没有可能strlen（token）==0？另外，发布所有代码。鉴于您对

FindClass（）

和

GetMethodID（）

的调用，您可能遗漏了一些失败的地方。注释：我得到strlen（token）的值总是23，它是从用于AES解密的get_token（）方法生成的。我从java得到一个空值。我在上面更新了一些错误日志信息。
