Android : App crashes with Signal 11 when OpenCV is added to the app

My basic application is I get the data and process in gpu to display on the screen. Before I added in OpenCV code into the app in the native c++, it works fine and can display the images on the screen. After I added in the following api into the native code, the app crashes with signal 11 error. How can I fix that error? My log error is shown in the bottom.

JNIEXPORT jlong JNICALL Java_UsbCamera_nativeCreateObject
(JNIEnv * jenv, jclass, jstring jFileName, jint faceSize)
{
    LOGD("Java_org_opencv_samples_facedetect_DetectionBasedTracker_nativeCreateObject enter");
    const char* jnamestr = jenv->GetStringUTFChars(jFileName, NULL);
    string stdFileName(jnamestr);
    jlong result = 0;
    LOGD(jnamestr);
    try
    {
        DetectionBasedTracker::Parameters DetectorParams;
        if (faceSize > 0)
            DetectorParams.minObjectSize = faceSize;

        result = (jlong)new DetectionBasedTracker(stdFileName, DetectorParams);
    }
    catch(cv::Exception& e)
    {
        LOGD("nativeCreateObject caught cv::Exception: %s", e.what());
        jclass je = jenv->FindClass("org/opencv/core/CvException");
        if(!je)
            je = jenv->FindClass("java/lang/Exception");
        jenv->ThrowNew(je, e.what());
    }
    catch (...)
    {
        LOGD("nativeCreateObject caught unknown exception");
        jclass je = jenv->FindClass("java/lang/Exception");
        jenv->ThrowNew(je, "Unknown exception in JNI code of DetectionBasedTracker.nativeCreateObject()");
        return 0;
    }

    LOGD("Java_org_opencv_samples_facedetect_DetectionBasedTracker_nativeCreateObject exit");
    return result;
}
