Question

나는 갑자기 충돌되는 앱 문제가 될 수도 어떻게 생각하십니까,

는 다음과 같은 코드가 지속적으로 호출 다음 충돌 데. 나는 그것이 원활하고 지속적으로 실행되기를 바랍니다.

SPropRecord* propRec = parseSPropParameterSets(fSubsession.fmtp_spropparametersets(), propNum); 
    __android_log_print(ANDROID_LOG_VERBOSE, "RTSP", "Frame: %c", propRec->sPropBytes); 
    jmethodID mid; 
    jclass handlerClass = env9->FindClass("ob/android/Stream"); 
    if (handlerClass == NULL) { 
     __android_log_print(ANDROID_LOG_VERBOSE, "RTSP-Error", "Class"); 
    } 
    mid = env9->GetStaticMethodID(handlerClass, "onResponse", "([B)V"); 
    if (mid == NULL) { 
     __android_log_print(ANDROID_LOG_VERBOSE, "RTSP-Error", "Method"); 
    } 

    jbyteArray jbArray = env9->NewByteArray((int)propRec->sPropLength); 
    env9->SetByteArrayRegion(jbArray, 0, (int)propRec->sPropLength, (jbyte*)propRec->sPropBytes); 

    //jobject theClass = env9->FindClass("ob/android/Stream"); 

    env9->CallStaticVoidMethod(handlerClass, mid, jbArray); 
    env9->DeleteLocalRef(jbArray); 

jbArray 참조를 릴리스합니다. 릴리스해야 할 것이 있습니까?

Answer 1

handlerClass를 해제해야합니다. 실제로 GetClockClass, "onResponse", "([B) V"]를 호출하고 이후 반복에서 메소드 ID를 재사용하기에 충분하므로 FindClass를 매번 호출 할 필요가 없습니다.
