使用相机时，如果取消拍摄，OnResultCallbackListener没有调用onCancel方法。

Start by reproducing camera cancellation with version 2.5.0 and trace the camera result handling around OnResultCallbackListener. The work is done when cancelling a camera capture invokes the listener's onCancel method; no specific source file or test is identified in the issue.
