Decoding qr code from image stored on the phone with Zxing (on Android phone)

Question

Hi! I have an app that receives qr code from the server. I want to decode it (not with intent and camera) and display the text it contains in my app. I have alredy done this in Java SE with jars from zxing with this code:

 private class QRCodeDecoder {
         public String decode(File imageFile) {
         BufferedImage image;
         try {
         image = ImageIO.read(imageFile);
         } catch (IOException e1) {
         return "io outch";
         }

         // creating luminance source
         LuminanceSource lumSource = new BufferedImageLuminanceSource(image);
         BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(lumSource));

         // barcode decoding
         QRCodeReader reader = new QRCodeReader();

         Result result = null;
         try {
         result = reader.decode(bitmap);
         } catch (ReaderException e) {
         return "reader error";
         }

         return result.getText();

         }
        }

But on Android, BufferedImage is not found. Has anyone decoded qr code on android from image stored on the phone? Tnx.
