Question

我正在编写自己的具有某些功能的相机应用程序。我想在我的应用中使用android相机的标准场景模式。因为我要求通过以下所有支持的场景模式

Camera.Parameters.getSupportedSceneModes()

对于我的手机（荣誉8c），我拥有所有可用的场景模式，包括hdr。设置任何场景模式后，一切都OK，可以拍照了。但是在致电

之后

Camera.Parameters parameters = mCamera.getParameters();
parameters.setSceneMode(scene_mode);
mCamera.setParameters(parameters);

然后过一段时间

mCamera.takePicture(shutterCallback, rawCallback, postviewCallback, mPicture);

我看到只有两个回调（快门和原始）有效，其他回调根本没有被调用。

调用takePicture方法后，我在Logcat中拥有的所有内容是：

D/MyApp: shutterCallback: works
D/MyApp: rawCallback: works
E/Camera: Error 1

我可以看到已拍摄照片并且相机的预览停止了，但是什么也没发生。

摄像机是否可能确实不支持hdr模式，但是getSupportedSceneModes会在支持的模式列表中返回hdr？如果是真的，那么如果该列表中有列表，该如何避免使用不受支持的场景模式？
也许在打开hdr模式时应该在快门或原始回调中做一些事情吗？

这是从调用setSceneMode方法开始的完整日志（Verbose和更高级别）：

这是调用takePicture方法后的日志：

仅此而已。然后，如果我隐藏我的应用并将其显示回去，则会看到以下日志：

现在，在重新启动相机之前，我无法在其应用中使用相机。没有例外，日志中只有错误消息。
