复现步骤： **蒙版显示状态下，放到后台后因系统资源限制销毁了Activity（可以打开不保留活动快速复现），再次打开蒙版Activity即可复现。** 原因： `重新打开已经被销毁的Activity时，系统会对Activity的状态进行恢复，包括Fragment的状态，此时V4ListenerFragment/ListenerFragment实例是由系统创建的，不会调用setFragmentLifecycle方法，所以mFragmentLifecycle为null，到onStart生命周期后就会抛出空指针异常。` 解决方案： ```kotlin override fun onActivityCreated(savedInstanceState: Bundle?) { super.onActivityCreated(savedInstanceState) // 手动移除监听Fragment val listenerFragment = childFragmentManager.findFragmentByTag("listener_fragment") as? V4ListenerFragment if (listenerFragment != null) { // 临时设置非空回调 listenerFragment.setFragmentLifecycle(object : FragmentLifecycleAdapter()...

Zoom value needs to be calculated according to maxZoom, **but there is no external api**. You can only get it using the Android Api `camera.getParameters().getMaxZoom()` You can refer [CodeScannerKtx.kt](https://gitlab.com/hushenghao/BarcodeScanner/-/blob/7f281a8c747b5f1972734aa4a00a3c3d28688541/app/src/main/java/com/atharok/barcodescanner/presentation/views/utils/CodeScannerKtx.kt) to...
