Question

我试图用Android中的JNI调用C源代码中的函数，但它崩溃了。

Android项目如下图所示。

enter image description here

JAVA中的代码如下：

public static native void startRTSPserver();
    static {
        Log.i(TAG, "Load Libraries...");
        System.loadLibrary("live555");
    }

当我在 startRTSPserver();

上调用功能 (SoftAP.java:302) 时，Android崩溃了

C源代码中的 live555MediaServer.cpp 代码如下：

#include <BasicUsageEnvironment.hh>
#include "DynamicRTSPServer.hh"
#include "version.hh"

JNIEXPORT void JNICALL Java_com_softap_SoftAP_startRTSPserver(JNIEnv *env , jobject thiz){
//int main(int argc, char** argv) {
        __android_log_print(ANDROID_LOG_INFO, "JNIMsg", "RTSP Start---live555MediaServer");
        // Begin by setting up our usage environment:
          TaskScheduler* scheduler = BasicTaskScheduler::createNew();
          UsageEnvironment* env = BasicUsageEnvironment::createNew(*scheduler);

          UserAuthenticationDatabase* authDB = NULL;
                                    .
                                    .
                                    .
}

错误日志如下所示：

有人知道它崩溃的原因吗？我错过了什么吗？

在C源代码中调用函数时出现“UnsatisfiedLinkError：未找到本机方法”
