return sout;
}

this not work, its freezes, my xml file is about 300 kb.

how i can handle this?

Try using a StringBuffer like this, the way you are doing it is very slow

public static String openAssetFile(Context ctx) {
    BufferedReader br=new BufferedReader(new InputStreamReader(
          ctx.getResources().openRawResource(R.raw.hung)));
    String readLine;
    StringBuffer sout= new StringBuffer();

    try {
        while ((readLine = br.readLine()) != null) {
            sout.append(readLine);
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
   return sout.toString();
}

Tried putting it in "/xml" and calling Resources.getXML(), or putting it in "/assets"?
