ANDROID split variable string

Question

I have a parsed a YouTube GDATA JSON-C file, and as such it is JSON the duration of each video does not have the : in between (it is parsed as 23 or 432 instead of 0:23 or 4:32) how would i split a string before the last 2 characters without knowing the length as it can be anywhere from 2 - 6 strings

public class Uploads  extends Activity {

static final String KEY_VIDEOITEM = "item"; 
static final String KEY_VIDEOID = "id";
static final String KEY_VIDEOTITLE = "title";
static final String KEY_VIDEODESCRIPTION = "description";
static final String KEY_VIDEOCOUNT = "viewCount";
static final String KEY_VIDEODURATION = "duration";
static final String KEY_VIDEODURATIONFORMATTED = "duration";
static final String KEY_VIDEOTHUMB_URL = "thumb_url";
static final String KEY_VIDEOURL = "videourl";
static String Duration = "duration";

ListView list;
org.scouts.android.videos.LazyAdapter adapter;

/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.video_lsitview);
    TextView lblTitle = (TextView) findViewById(R.id.actionbar);
    lblTitle.setText("Uploads");



    ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();

    //Get the data (see above)
    //JSONObject json = getJSON.getJSONfromURL("http://gdata.youtube.com/feeds/api/users/worldscouting/playlists?alt=jsonc");

    HttpClient client = new DefaultHttpClient();
    // Perform a GET request to YouTube for a JSON list of all the videos by a specific user
    HttpUriRequest request = new HttpGet("http://gdata.youtube.com/feeds/api/users/worldscouting/uploads?v=2&alt=jsonc");
    // Get the response that YouTube sends back
    HttpResponse response = null;
    try {
        response = client.execute(request);
    } catch (ClientProtocolException e1) {

        e1.printStackTrace();
    } catch (IOException e1) {

        e1.printStackTrace();
    }
    // Convert this response into a readable string
    String jsonString = null;
    try {
        jsonString = StreamUtils.convertToString(response.getEntity().getContent());

        json = new JSONObject(jsonString);
    } catch (JSONException e1) {

           try{



               //JSONArray  earthquakes = json.getJSONObject("data").getJSONArray("items");
               JSONArray jsonArray = json.getJSONObject("data").getJSONArray("items");
                //Loop the Array
        for(int i=0;i < jsonArray.length();i++){                        

            HashMap<String, String> map = new HashMap<String, String>();
            JSONObject jsonObject = jsonArray.getJSONObject(i);
            //JSONObject uploads = earthquakes.getJSONObject(i);

            map.put("id",  String.valueOf(i));
            map.put("videoid", jsonObject.getString("id"));

            map.put(KEY_VIDEOTITLE, jsonObject.getString(KEY_VIDEOTITLE));

            mylist.add(map);




        }

           list.setOnItemClickListener(new OnItemClickListener() {

                String videourl = ((TextView) view.findViewById(R.id.video_id)).getText().toString();

                Uri uri = Uri.parse(videourl);
                startActivity( new Intent( Intent.ACTION_VIEW, uri ) );

public class string { public static void main(String[] args) {

String str= "45";
String op=addToString(str, ":");
System.out.println(op);
}
static String addToString(String str,  String ins) {
    if(str.length()<=2)
    {
        str="00"+str;
    }
    int i = str.length()-(str.length()-2);
    return str.substring(0, i) + ins + str.substring(i);
}

}
