④现象 由于二维码内容较多，识别耗时相对较长，偶现OOM闪退，Profiler观察到扫描二维码时内存有飙升，不扫描时app占用100MB内存左右，扫描时内存占用迅速上升，如果长时间没扫描出结果，到占用300多MB内存的时候，会抛出OOM闪退。部分机型复现概率稍低，多次重复扫描成功后，重新打开扫描Activity扫描这个操作，也容易复现。
出现这种OOM的情况一般有如下两种解决方案：
- 可以在清单文件Manifest的application中添加如下配置：
android:largeHeap="true" - 根据需求场景，可以适当的调整下分析图像的质量；即：CameraConfig 相关配置。
