You should likely store the result on a server and then have the device query your server for the result in JSON and then use that collection of images in the JSON data and handle it that way. Because this result can change you should do it each time your application is started (of course you'd have to tweak this to whatever your extent).

Create file using coma(,)

1) Get data from server uploaded file and get response in res

2) call method String filecontentString = readContentFromResponse(res);

public String readContentFromResponse(String res) {
    BufferedReader reader = null;
    StringBuilder sb = new StringBuilder();
    try {
      reader = new BufferedReader(new InputStreamReader(new FileInputStream(new File(res))));
      String line = null;
      while ((line = reader.readLine()) != null) {
        sb.append(line);
      }
    } catch (IOException e) {
      Log.e("TAG",e);
    } finally {
      if (reader != null) {
        try {
          reader.close();
        } catch (IOException e) {
          Log.e("TAG",e);
        }
      }
    }
    return sb.toString();
  }

3) Then create empty String array

String[] IMAGES ={};

IMAGES = filecontentString.split(",");

see my updated code in my question and tell me how to Read this file content and store in String object, sample code please — android overflow, Aug 18 '14 at 11:39
