Question

我一直在调试此错误3天。在我的Android项目中，我试图从Native Code中抛出异常。我创建了自己的异常类，它扩展了标准Java异常类。以下是我从Native Code中抛出Exception的方法。

extern "C" JNIEXPORT void JNICALL Java_com_company_MyClass_nativeCall(JNIEnv *env, jclass type)
{
    // Other code stuffs
    jclass clazz = env->FindClass("com/company/MyExceptionClass"); 
    env->ThrowNew(clazz, "Error");
}

但是当执行ThrowNew（）时，它会跟随

崩溃

我也尝试过使用throwable Object的env-＆gt; Throw（）。但行为是一样的。我认为它可能是平板电脑设备（索尼Z2）的动态libc支持问题所以我使用静态libc ++编译与Follow gradle文件。但它没有任何效果。我仍然得到了崩溃。

我真的很感激任何帮助。
