Display a picture taken with my android in my webapp

I’m trying to retrieve a photo taken in my android application and display it in my webview project; my web pages are local file:///android_asset/

with this function snapet i can launch the camera

   @JavascriptInterface 
    public void prendreUnePhoto() {
                        
                  Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                  pickMedia.launch(intent);
            }

// the callbak

  ActivityResultLauncher<Intent> pickMedia =
                    registerForActivityResult(new ActivityResultContracts.StartActivityForResult(), result-> {
                       
                        if (result.getResultCode() == RESULT_OK && result.getData() !=null) {
                            Log.d("PhotoPicker", "Selected URI: " + result.getData().getExtras());
                            Bundle bundle = result.getData().getExtras();
                            Bitmap bitmap = (Bitmap) bundle.get("data");
                            b= (Bitmap) bundle.get("data");
                           
                        } else {
                            Log.d("PhotoPicker", "No media selected");
                        }
                    });

Here i convert the photo taken in Base64

@JavascriptInterface
        public String getPhoto() {
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.PNG, 10, stream);
            byte[] bytesArray = stream.toByteArray();
            String str = Base64.encodeToString(bytesArray, Base64.DEFAULT);


            return str;
        }

then from the webapp side (webview client) i can launch the camera (JAVASCRIPT SNIPPET)

 but.addEventListener("click", () => {
         
          v = Android.prendreUnePhoto();
          Android.getPhoto();
         
        });

I would like to know how i can display the photo taken by the camera directly on a div on my client (webview)

I’m oblige to create another button then I can call the function getPhoto() and by this way i can display the photo taken

 verifier.addEventListener("click", () => {
          var b = Android.getPhoto();
          var src = "data:image/jpeg;base64," + b;
          $("#img").append(`<img src="${src}"/>`);
          console.log(src);
          //alert(typeof b);
        });
