释放相机会终止任务中的所有活动

Question

我有一个视频录制应用程序，在其中使用 Camera 对象设置相机参数。录制完成后，在 onPause 中，我使用方法

camera.unlock();
释放相机 相机.release();
当我的相机被释放时，我得到以下日志

正如您在日志底部看到的那样，发生了一些胜利死亡事件，这基本上杀死了我之前所有未完成的活动。这给我带来了很多问题，因为它阻碍了我的申请流程。

有什么想法可能是什么问题吗？

Answer 1

在 camera.unlock() 之前尝试 camera.setPreviewCallback(null);
相机.release();
