使用的是zbar，截止到现在的最新版
从主界面进入扫描界面返回再进入反复几次后 ，会出现这个报错(代码回调的报错没有任何回调，只有这点日志报错)，摄像头预览画面卡死(有预览画面，一般是点进去1~5s才预览卡死，也有很多情况是扫描过程中才出现预览画面卡死)，可以手动调用stopcamera和startcamera恢复，但是没有代码里没有可以监听异常的地方就特别难受
开始以为是相机对象回收的问题，但是我这边也是 oncreate里zbarview.setDelegate(this); onstart里 zbarview.startSpotAndShowRect(); onStop里zbarview.stopCamera(); onDestroy里zbarview.onDestroy();
试过把onstart和onStop里的换到 onResume和onPause，也看过网上的什么延时0.1~0.5s打开相机(startCamera)，但是都无效...
出现有一定的随机性，手上几台测试机，小米8出现的频率比较低，试个几十次才会出现一次，oppo(K1)的就异常高，大概4~5次就会出现
另外还会出现黑屏情况，但是这个是可以捕捉到的，设置个延时stop再start问题其实也不大 看起来像是回收的问题，最后都会出现Camera: Error 2
