你好，可以从native侧的生命周期等回调中获取native window句柄

回复 kuaile: 你好，我在native侧的回调获取native Window句柄的时候，遇到这个问题： OHNativeWindowBuffer *buffer = nullptr;
int fenceFd;
// 通过 OH_NativeWindow_NativeWindowRequestBuffer 获取 OHNativeWindowBuffer 实例
ret = OH_NativeWindow_NativeWindowRequestBuffer(nativeWindow, &buffer, &fenceFd);
这个操作会报错 OH_NativeWindow_NativeWindowRequestBuffer ret = 40601000。

这是具体的日志

回复 kuaile: 具体可能是什么原因造成的勒？我最开始设置的是320*240，用api接口获取size也是正常的
