내 C++ JNI에서 충돌을 일으키는 원인은 무엇입니까?

Question

내 C++ 클래스에서 페이스 북 로그인을 구현하려고합니다. 자바에서 나는 사용자의 페이스 북 정보를 얻으려고 노력하고있다. 모든 것이 Java에서 C++로 올바르게 전달됩니다. 이 코드 조각이 주석 때

그러나, (여기에 다른 유사한 답변에 따라 메모리 문제) 신호 (11) 내 응용 프로그램 충돌이 개 라인 아래

JNIEXPORT void JNICALL Java_com_humit_android_HumIt_javaCallJNI(JNIEnv* env, jobject obj, 
             jstring javaString1, jstring javaString2, jstring javaString3) 
{ 
    //Get the native string from javaString 
    const char *nativeString1 = env->GetStringUTFChars(javaString1, 0); 
    const char *nativeString2 = env->GetStringUTFChars(javaString2, 0); 
    const char *nativeString3 = env->GetStringUTFChars(javaString3, 0); 

// 오류를주고있다. .. 만약 코멘트, 아무 문제 ...!

LoginScreen * loginScreen = new LoginScreen(); 
    loginScreen->facebookProfileInfoFetch("hi", "hii", "hii"); 




    env->ReleaseStringUTFChars(javaString1, nativeString1); 
    env->ReleaseStringUTFChars(javaString2, nativeString2); 
    env->ReleaseStringUTFChars(javaString3, nativeString3); 

} 

facebookProfileInfoFetch은 다음과 같습니다

void LoginScreen::facebookProfileInfoFetch(const char * value1, const char * value2, const char * value3) { 
LOGD(" ----------------- facebookProfileInfoFetch ------------- %s ------------ ", value1); 
LOGD(" ----------------- facebookProfileInfoFetch ------------- %s ------------ ", value2); 
LOGD(" ----------------- facebookProfileInfoFetch ------------- %s ------------ ", value3); 

facebookUserName = value1; 
facebookUserId = value2; 
facebookUserGender = value3; 

this->loginHumServer(); 

} 

loginHumServer()가 호출 될 때 충돌되는 :

loginhumserver는()입니다 :

void LoginScreen::loginHumServer() 
{ 
LOGD(" ----------------- loginHumServer ------------------------- "); 
facebookDataRetrievedCount++; 

if(facebookDataRetrievedCount<2) 
    return; 


CCHttpRequest* request = new CCHttpRequest(); 
LOGD(" ----------------- constructing url ------------------------- "); 
std::string url="http://humsrer.co.in/user/sign_in?"; 
url=url+"name"+"="+facebookNoSpaceUserName+"&"; 
url=url+"facebook_thumbnail"+"="+facebookUserPictureUrl+"&"; 
url=url+"facebook_id"+"="+facebookUserId+"&"; 
url=url+"gender"+"="+facebookUserGender+"&"; 
url=url+"ios_push_id"+"="+"12346"; 

CCLog("UUUUUUUUUUUUUUUUUUU %s ",url.c_str()); 
request->setUrl(url.c_str()); 
request->setRequestType(CCHttpRequest::kHttpGet); 
request->setResponseCallback(this, callfuncND_selector(LoginScreen::onHttpRequestCompleted)); 
// optional fields 
request->setTag("GET test2"); 
LOGD(" ----------------- loginHumServer getInstance ------------------------- "); 
CCHttpClient::getInstance()->send(request); 

// don't forget to release it, pair to new 
request->release(); 
LOGD(" ----------------- loginHumServer request->release ------------------------- "); 
loginLabel->setString("Loging to hum server.."); 
} 

이는 로그 캣입니다 앱 충돌시 발생하는 오류 :

Answer 1

당신은 잘못된 위치를 가리키는 곳의 포인터를 가지고 :

편집 나는 onHttpRequestCompleted 방법을 추가했습니다. 이것이 세분화 오류의 원인입니다. 크래시가 LoginScreen::onHttpRequestCompleted에서 시작되는 것 같습니다. 게시 할 수 있습니까?

Answer 2

assert()가 실행 중입니다. 당신은 매우 구체적인 주소에 실패하고 있습니다 :

INFO/DEBUG(5637): signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr deadbaad 

0xdeadbaad는 생체 공학 중단() 함수에 의해 사용됩니다. (모든 사람이 좋아 - http://code.google.com/p/android/issues/detail?id=16672를 참조하십시오.) 당신이 실패하는 경우

스택 추적을 설명 : 정의

INFO/DEBUG(5637):   #00 pc 000179d8 /system/lib/libc.so 
INFO/DEBUG(5637):   #01 pc 0001ef44 /system/lib/libc.so (__assert2) 
INFO/DEBUG(5637):   #02 pc 000fb552 /data/data/com.humit/lib/libgame.so (_ZN11LoginScreen22onHttpRequestCompletedEPN7cocos2d6CCNodeEPv) 
INFO/DEBUG(5637):   #03 pc 001c3e32 /data/data/com.humit/lib/libgame.so (_ZN7cocos2d9extension12CCHttpClient25dispatchResponseCallbacksEf) 

주 __assert2, 생체 공학의 < > assert.h를.

LoginScreen::onHttpRequestCompleted(cocos2d::CCNode*, void*)에서 호출됩니다. 라이브러리의 심볼과 함께 주소 - 행 도구를 사용하여 특정 행 번호로 변환 할 수 있지만 실패한 주장 자체는 네이티브 충돌 바로 위에있는 logcat에 표시되는 것이 이상적입니다.
