JNI类型不正确的错误。

http://blog.csdn.net/xiongmc/article/details/8970036

情境如下：当你在C#中调用JNI的方法时，会存在Invalid indirect reference 0x5a02d6e0 in decodeIndirectRef错误。例如：testdemo.cpp文件中的类型为char* requestId ，在调用CallStaticVoidMethod方法时，就存在了这种错误。为什么？问题是requestId传递的是数字型的字符串，你需要NewStringUTF转换string类型。否则编译时会将你的字符串的数字型看成是引用类型，事实上，不是作为引用类型，它是简单的数字。

test.cpp

void FlyfotMembership_createFriendshipRequest(char* requestId,char* Yodo1SetCallbackGameObj,char* Yodo1SetCallbackMethodName,char* Yodo1SetCallbackContextParams){
LOGI("createFriendshipRequest");
jclass cls = getUnitySupportMms();
if(cls != NULL){
jmethodID id = jni_env->GetStaticMethodID(cls,cn_UnitySupportMms_createFriendshipRequest,cn_UnitySupportSns_createFriendshipRequest_params);
if(id!=NULL){
LOGI("createFriendshipRequest methodID=%d",id);
jni_env->CallStaticVoidMethod(cls,id,
requestId,
jni_env->NewStringUTF(Yodo1SetCallbackGameObj),
jni_env->NewStringUTF(Yodo1SetCallbackMethodName),
jni_env->NewStringUTF(Yodo1SetCallbackContextParams));
}
}


  }

错误log如下：

java层实现：

public static void createFriendshipRequest(String requestId, String callbackGameObj,
String callbackMethodName, String callbackContextParams) {
//todo.....
};

解决方案为：

void FlyfotMembership_createFriendshipRequest(char* requestId,char* Yodo1SetCallbackGameObj,char* Yodo1SetCallbackMethodName,char* Yodo1SetCallbackContextParams){
LOGI("createFriendshipRequest");
jclass cls = getUnitySupportMms();
if(cls != NULL){
jmethodID id = jni_env->GetStaticMethodID(cls,cn_UnitySupportMms_createFriendshipRequest,cn_UnitySupportSns_createFriendshipRequest_params);
if(id!=NULL){
LOGI("createFriendshipRequest methodID=%d",id);
jni_env->CallStaticVoidMethod(cls,id,
jni_env->NewStringUTF(requestId),
jni_env->NewStringUTF(Yodo1SetCallbackGameObj),
jni_env->NewStringUTF(Yodo1SetCallbackMethodName),
jni_env->NewStringUTF(Yodo1SetCallbackContextParams));
}
}
