Hi
I get the FileNotFoundException while I try to access the selected file (via UIImagePickerController) using the following code :

   imagePickerController.setDelegate(new UIImagePickerControllerDelegate() {
            @Override
            public void imagePickerControllerDidFinishPickingMediaWithInfo(UIImagePickerController picker, NSDictionary<String, ?> info) {
                /*
                for(String key : info.keySet()){
                    Foundation.NSLog("key= " + key + "|| value= " + info.valueForKey(key).toString()  );
                }
                */
                String filePath = info.valueForKey("UIImagePickerControllerImageURL").toString();
                //UIImagePickerControllerReferenceURL
                //UIImagePickerControllerImageURL
                File file = new File(filePath);
                Foundation.NSLog("selected file path = '" + filePath + "' size =" + file.length());
                try{
                    FileInputStream fos = new FileInputStream(file);
                    byte[] data = new byte[(int)file.length()];
                    fos.read(data);
                    fos.close();
                }catch (FileNotFoundException ex){
                    ex.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }

                picker.dismissViewControllerAnimatedCompletion(true,null);
            }

plist :

<key>NSPhotoLibraryUsageDescription</key>
<string>You can select photos to attach to reports.</string>

output:

Hi,

The java file api works with paths, and you are passing a file:// URL. You need to convert it to a path eg. by stripping the file: from the beginning.

I removed “file:///” and it works
