Getting list of subfolders name and files name in android source package

I'm developing an android application that store sql files to update the sqlite database. And that sql script will run when user push certain button. This is where i put my sql files

So far i've been using this solution to run my script: First, mapping my update to resource as update.xml

<resources>    

    <string name="update_list">
        v2_9_11
    </string>

    <string-array name="v2_9_11">
        <item>1_AlterTable_wapactivity</item>
    </string-array>

</resources>

And get the sql script inside the file with this method :

private void runScript(String version_name){
        try{
            String[] sql_list = mGap.getResources().getStringArray(getArrayIdentifier(mGap, version_name));
            for (String sql : sql_list) {
                InputStream in =  getClass().getResourceAsStream("/com/ods/scm/script/update/"+version_name+"/"+sql+".sql");
                Reader fr = new InputStreamReader(in, "utf-8");
                BufferedReader br = new BufferedReader(fr);
                String s="";
                String baris;
                while((baris=br.readLine())!=null){
                    s+=baris;
                 }
                mDbHelper.executeStatement(s);
            }
            insertUpdate(version_name);
        }
        catch(Exception e){
            System.out.println(e.getMessage());
        }
    }

I get the String version_name and String[ ] sql_list file name from update.xml. The problem is, i want to get version_name ( in this case v2_9_11 as subfolder name from folder update ) and sql file name ( in this case 1_AlterTable_wapactivity.sql ) without mapping it in update.xml. Can ayone help me?

EDIT
Or can anyone direct me how to automatically mapping it to update.xml when build the application?

I suggest you put the .sql file in assets folder. By doing that, you are free to manipulate your file with File IO API.

Sorry all, i just now put it in bounty but i'm able to resolve it by myself by the short time after i put it in bounty. Anyway, my solution is to open the apk file that inside the android device (data/app/....apk) as a zip stream. Then list all the file that start with com/ods/scm/script/update. Here my method to get all file that start with it :

public ArrayList openApk(String filePath){
  ArrayList<String> list = new ArrayList<String>();
  FileInputStream fis = null;
  ZipInputStream zipIs = null;
  ZipEntry zEntry = null;
  try {
      fis = new FileInputStream(filePath);
      zipIs = new ZipInputStream(new BufferedInputStream(fis));
      while((zEntry = zipIs.getNextEntry()) != null){
        if(zEntry.getName().startsWith("com/ods/scm/script/update/"))
          list.add(zEntry.getName());
      }
      zipIs.close();
  } catch (FileNotFoundException e) {
      e.printStackTrace();
  } catch (IOException e) {
      e.printStackTrace();
  }
  return list;
}
