Android: Remove specific part of string that is inside a jsonObject, inside an arraylist

I have a class called GamesData that has strings and getters and setters for this strings.

I download strings from a json. One of these strings is an URL with an image. I download the images but on a small size, because of their URL. I need to download it on a bigger size. For this, I need to remove this "small" string from the URL:

"home_team_logo": "https:\/\/URL\/images\/teams\/small\/olympique-marseille-890.png"

I have more than one URL coming from a big json object, all inside a json array, formated like the one above.

This is what I do to get the json.

arrayList.add(new GamesData(
                                gamesDataObject.getString(TAG_DATE),
                                gamesDataObject.getString(TAG_COMPETITION),
                                gamesDataObject.getString(TAG_HOME_TEAM),
                                gamesDataObject.getString(TAG_AWAY_TEAM),
                                gamesDataObject.getString(TAG_ID)
                        ));

I need to remove from TAG_HOME_TEAM

    public static final String TAG_HOME_TEAM= "home_team_logo";

, which is that URL above, only the "small" part, so the image downloaded will be the full size one.

In fact I will need this for all 3 tags: TAG_COMPETITION, TAG_HOME_TEAM, TAG_AWAY_TEAM.

How on earth do I do this? xD

I'm thinking something like this might work:

gamesDataObject.getString(TAG_HOME_TEAM).replaceAll("\/small\/","/");

This uses a regular expression to match all occurrences of the patern. A simplepr less error prone approach may be to use 

gamesDataObject.getString(TAG_HOME_TEAM).replace("\/small\/","/");

Which should only replace the first occurrence.

You can use replace , use /small/ with / as replacement to avoid matching something like /othersmallteamname/

       String s = "https:/URL/images/teams/small/olympique-marseille-890.png";
       System.out.println(s.replace("/small/", "/"));

Output :

https:/URL/images/teams/olympique-marseille-890.png
