Android NDK：无法调用C++构造函数

我正在尝试使用NDK将一个C++桌面程序移植到Android上。当我重新启动时，我发现在初始化类Windows时没有调用类Constants的构造函数，而是将width_和height_保留为0，并且调用跟踪很奇怪。

联系方式：
https://github.com/speedyHKjournalist/OpenMapleClient/blob/main/app/src/main/cpp/src/IO/Window.cpp#L34
从跟踪看，似乎没有调用Error Game：：init（android_app *pApp）？
跟踪：

正如@user17732522正确指出的那样，您无法保证初始化顺序。
因此，我将Singleton类更改为：

template<class T>
class Singleton {
public:
    virtual ~Singleton() = default;

    static T &get() { 
        static T instance_;
        return instance_;
    }

private:
    T &operator=(const T &) = delete;
};

// No need for the code above
// template<class T>
// T Singleton<T>::instance_;
