        TextView helpText =(TextView) findViewById(R.id.TextView_HelpText);
        String strFile = inputStreamToString(iFile);

    }

    private String inputStreamToString(InputStream iFile) {
        // TODO Auto-generated method stub
        return null;
    }

    private void openRawResource() {
        // TODO Auto-generated method stub

    }
}

```

Answer: 
Well... for one, you are returning `null` from `inputStreamToString(...)`. You need to implement it correctly before you can expect it to return anything.
change

```
private String inputStreamToString(InputStream iFile) {
    // TODO Auto-generated method stub
    return null;
}

```

with

```
private String inputStreamToString(InputStream iFile) 
{               
    Writer writer = new StringWriter();
    if(iFile!=null)
    {
        char[] buffer = new char[1024];
        try{
            Reader reader = new BufferedReader(
                    new InputStreamReader(iFile, "UTF-8"));
            int n;
            while ((n = reader.read(buffer)) != -1) {
                writer.write(buffer, 0, n);
            }
        } catch (UnsupportedEncodingException e) {
            return e.toString();
        } catch (IOException e) {
            return e.toString();
        }finally
        {
            try {
                iFile.close();
            } catch (IOException e) {
                return e.toString();
            }
        }
    }
   String result = writer.toString();
   return result;
}

```
