Problem uploading a photo to a web server

Question

Hi! I’m having a problem uploading a photo taken from an android app to a web server. On the local server it usually sends the photo, already on the web server, it sends only one photo and only sends another if it clears the application cache on android. Below is the code responsible for taking the photo and sending to the server. Thanks to those who can help.

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            getFileUri();
            i.putExtra(MediaStore.EXTRA_OUTPUT, file_uri);
            startActivityForResult(i, 10);
        }
    });
}

private void getFileUri() {

    image_name = "teste123.jpeg";
    file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
            + File.separator + image_name
    );

    file_uri = Uri.fromFile(file);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == 10 && resultCode == RESULT_OK) {
        new Encode_image().execute();
    }
}

private class Encode_image extends AsyncTask<Void, Void, Void> {
    @Override
    protected Void doInBackground(Void... voids) {

        bitmap = BitmapFactory.decodeFile(file_uri.getPath());
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
        bitmap.recycle();

        byte[] array = stream.toByteArray();
        encoded_string = Base64.encodeToString(array, 0);
        return null;
    }

    @Override
    protected void onPostExecute(Void aVoid) {
        makeRequest();
    }
}

private void makeRequest() {
    RequestQueue requestQueue = Volley.newRequestQueue(this);

            StringRequest request = new StringRequest(Request.Method.POST, "http://teste.com.br/servidor/package/photo/connection.php",

            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {

                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    }) {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            HashMap<String,String> map = new HashMap<>();
            map.put("encoded_string",encoded_string);
            map.put("image_name",image_name);

            return map;
        }
    };
    requestQueue.add(request);
    Toast.makeText(CarActivity.this, "Foto enviada com sucesso.", Toast.LENGTH_SHORT).show();
}
