jni文件传递方法参数

使用jni从java传递多个参数到c++时，如果是多个参数，当是string类型时，参数之间用;分割 

void sendToAndoridAdmobId(const char* id)
{
    JniMethodInfo methodInfo;


    if (!JniHelper::getStaticMethodInfo(methodInfo, JavaTool_ClassName, "setDomobUnitId", "(Ljava/lang/String;)V"))
    {
        return;
    }
    jstring l_stringUrl = methodInfo.env->NewStringUTF(id);
    methodInfo.env->CallStaticVoidMethod(methodInfo.classID, methodInfo.methodID, l_stringUrl);
    methodInfo.env->DeleteLocalRef(methodInfo.classID);

}

对应的java代码 

public static void  setDomobUnitId(String id)
{
 JavaTool.DOMOB_UNIT_ID = id;
}

但是如果是int类型，就直接挨在一起写了 

void sendToAndoridWidthHeight(int width ,int height)
{
    JniMethodInfo methodInfo;


    if (! JniHelper::getStaticMethodInfo(methodInfo, JavaTool_ClassName, "sendToAndroidWidthHeight", "(II)V"))
    {
        return;
    }


    methodInfo.env->CallStaticVoidMethod(methodInfo.classID, methodInfo.methodID, width,height);
    methodInfo.env->DeleteLocalRef(methodInfo.classID);
}

对应的java代码 

public static void  sendToAndroidWidthHeight(int width , int height)
{
 JavaTool.width = width;
 JavaTool.height = height;
}

可以用javap   -s   -p   yourclassname 这个命令得到内部类型签名
