Android 未调用APP_CMD_WINDOW_RESIZED，但已调整本机窗口的大小

我有一个本机应用程序，它被配置为不破坏设备方向更改时的活动

<activity android:name="android.app.NativeActivity"
    ...
    android:configChanges="orientation|screenSize"
    ...
    >

在命令处理程序中，我可以看到使用

ANativeWindow\u getHeight

函数更改了窗口大小

（我知道

ANativeWindow\u getHeight

函数不是在配置更改处理程序中使用以获取窗口大小的最佳方法，我只需要检查窗口是否已调整大小。）

如果调整了本机窗口的大小，我想应该触发以下本机命令

/**
 * Command from main thread: the current ANativeWindow has been resized.
 * Please redraw with its new size.
 */
APP_CMD_WINDOW_RESIZED

---

为什么它被阻止了？

我自己找到了原因

android原生应用程序glue没有用于触发

app\u CMD\u WINDOW\u RESIZED

命令的代码。但只有它的定义

原因是，没有注册本机回调

onNativeWindowResized

void ANativeActivity_onCreate(ANativeActivity* activity, 
                             void* savedState, size_t savedStateSize) {
    LOGV("Creating: %p\n", activity);
    activity->callbacks->onDestroy = onDestroy;
    activity->callbacks->onStart = onStart;
    activity->callbacks->onResume = onResume;
    activity->callbacks->onSaveInstanceState = onSaveInstanceState;
    activity->callbacks->onPause = onPause;
    activity->callbacks->onStop = onStop;
    activity->callbacks->onConfigurationChanged = onConfigurationChanged;
    activity->callbacks->onLowMemory = onLowMemory;
    activity->callbacks->onWindowFocusChanged = onWindowFocusChanged;
    activity->callbacks->onNativeWindowCreated = onNativeWindowCreated;
    activity->callbacks->onNativeWindowDestroyed = onNativeWindowDestroyed;
    activity->callbacks->onInputQueueCreated = onInputQueueCreated;
    activity->callbacks->onInputQueueDestroyed = onInputQueueDestroyed;
    activity->instance = android_app_create(activity, savedState, savedStateSize); 
}

最后，它没有注册的原因是一个android错误

本机回调的文档是

我无法证明这一点，但我怀疑bug报告有点不准确，而且在应用程序启动时，surfaceChanged不会被多次调用。见：

void ANativeActivity_onCreate(ANativeActivity* activity, 
                             void* savedState, size_t savedStateSize) {
    LOGV("Creating: %p\n", activity);
    activity->callbacks->onDestroy = onDestroy;
    activity->callbacks->onStart = onStart;
    activity->callbacks->onResume = onResume;
    activity->callbacks->onSaveInstanceState = onSaveInstanceState;
    activity->callbacks->onPause = onPause;
    activity->callbacks->onStop = onStop;
    activity->callbacks->onConfigurationChanged = onConfigurationChanged;
    activity->callbacks->onLowMemory = onLowMemory;
    activity->callbacks->onWindowFocusChanged = onWindowFocusChanged;
    activity->callbacks->onNativeWindowCreated = onNativeWindowCreated;
    activity->callbacks->onNativeWindowDestroyed = onNativeWindowDestroyed;
    activity->callbacks->onInputQueueCreated = onInputQueueCreated;
    activity->callbacks->onInputQueueDestroyed = onInputQueueDestroyed;
    activity->instance = android_app_create(activity, savedState, savedStateSize); 
}
