DCVCameraView will get stuck after multiple times of render

[ysuobunnings]

Hi Dynamsoft Team,

 We are currently experiencing App stuck while using "dynamsoft-capture-vision-react-native": "^1.1.11", upgrade to 1.1.12 will not resolve the issue.

Environment for our App:

React-native: 0.73.6 or 0.72.9(another project that also have same issue) Node: 18.19.1

Issue description:

  Our project is react-native based and uses DCVCameraView in our component. The stuck issue will appear when you have rendered the DCVCameraView around 15 Times. If you repeat the process of opening the scanner then scanning a barcode, navigating to another screen, returning to the home page, and restarting the scanner component which contains the DCVCameraView component, you may see stuck by chance. Sometimes happens when you open on your second try, and sometimes after 20 times attempts.   To lock the cause of the stuck, we tried to trim the hooks that caused re-rendering but still happened. I checked DCVBarcodeReader initialise process, and everything follows the instructions and DCVBarcodeReader.initLicense has only been called for 1 time. To get rid of all the other possible reasons that cause the stuck, we set a button in our scanner screen and only render a pure DCVCameraView with a simple style. we wait for all hooks and re-render to be finished and also for the reader to be initialised and only then click the button and render DCVCameraView, App will still get stuck. so we think it’s time to raise an issue and see if the Dynamsoft team can help us dig and investigate the root cause of it.   Here is the recording, looks like it get stuck when the camera is about to turn on.

another project also has the same issue, the scanner page will get stuck after multiple times of render. @ysuobunnings @siyang-bunnings

Hi @ysuobunnings We might need some further information to solve this issue: 1) Is the issue on Android or iOS or both? 2) If you received any error message, please send us. 3) Can you provide us with your sample code or a simplified project to reproduce the issue? Or at least send us a screen record to help us to reproduce the stuck.

Hi Henry, thanks for providing the new version, but when we try to test it, we have build issue for android in both local and pipeline. here are the error message: `Task :dynamsoft-capture-vision-react-native:compileDebugJavaWithJavac /bitrise/src/node_modules/dynamsoft-capture-vision-react-native/android/src/main/java/com/dynamsoft/reactlibrary/RNDCECameraView.java:82: error: cannot find symbol View btnTorch = findViewById(R.id.btn_torch); ^ symbol: variable id location: class R Note: Some input files use or override a deprecated API.

• What went wrong: Execution failed for task ':dynamsoft-capture-vision-react-native:compileDebugJavaWithJavac'.`

did you team test the new version for android, or maybe the new version is not work for RN 0.73?
