Read file As String

Question

I need to load an xml file as String in android so I can load it to TBXML xml parser library and parse it. The implementation I have now to read the file as String takes around 2seconds even for a very small xml file of some KBs. Is there any known fast method that can read a file as string in Java/Android?

This is the code I have now:

public static String readFileAsString(String filePath) {     String result = "";     File file = new File(filePath);     if ( file.exists() ) {         //byte[] buffer = new byte[(int) new File(filePath).length()];         FileInputStream fis = null;         try {             //f = new BufferedInputStream(new FileInputStream(filePath));             //f.read(buffer);              fis = new FileInputStream(file);             char current;             while (fis.available() > 0) {                 current = (char) fis.read();                 result = result + String.valueOf(current);             }         } catch (Exception e) {             Log.d("TourGuide", e.toString());         } finally {             if (fis != null)                 try {                     fis.close();                 } catch (IOException ignored) {             }         }         //result = new String(buffer);     }     return result; }

The code finally used is the following from:

http://www.java2s.com/Code/Java/File-Input-Output/ConvertInputStreamtoString.htm  public static String convertStreamToString(InputStream is) throws Exception {     BufferedReader reader = new BufferedReader(new InputStreamReader(is));     StringBuilder sb = new StringBuilder();     String line = null;     while ((line = reader.readLine()) != null) {       sb.append(line).append("\n");     }     reader.close();     return sb.toString(); }  public static String getStringFromFile (String filePath) throws Exception {     File fl = new File(filePath);     FileInputStream fin = new FileInputStream(fl);     String ret = convertStreamToString(fin);     //Make sure you close all streams.     fin.close();             return ret; }
