App Crashes: FATAL EXCEPTION: pool-109-thread-1 (java.lang.IllegalArgumentException: Each request must have at least one Surface target)

Hello @khoren93,

I have an issue encountering recently in this package when uploading the images from the ReaderWidget. When I continuously uploads the images from the gallery consequently 10~15 times, the app is being crashed and throwing the errors as shown below:

E/AndroidRuntime(13388): FATAL EXCEPTION: pool-109-thread-1

There was some information about this error in the CameraDeviceImp code, here is the link to it.

// Make sure that there all requests have at least 1 surface; all surfaces are non-null;
for (CaptureRequest request : requestList) {
   if (request.getTargets().isEmpty()) {
     throw new IllegalArgumentException(
     "Each request must have at least one Surface target");
   }
  
   for (Surface surface : request.getTargets()) {
     if (surface == null) {
         throw new IllegalArgumentException("Null Surface targets are not allowed");
     }
   }   
}
 

@khoren93 Could you please help me in resolving this issue ? or any suggestions to avoid this issue also appreciated.

Thanks
