Question

I get this error while accessing a php script:

W/System.err: Error reading from ./org/apache/harmony/awt/www/content/text/html.class

The offending code snippet is as follows:

URL url = "http://server.com/path/to/script"
is = (InputStream) url.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
    sb.append(line + "\n");
}
is.close();

The error is thrown on the second line. A Google search on the error turned up 0 results. This warning doesn’t affect the flow of my application and its more an annoyance rather than a problem. it also only occurs on a API 11 device (works fine on API 8 & 9 devices)

If you’re querying a PHP script, I’m pretty sure declaring a URL and then trying to get an InputStream off it isn’t the right way to do it…

Try something like:

HttpClient httpclient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://someurl.com");

try {
// Execute HTTP Get Request
HttpResponse response = httpclient.execute(httpGet);

HttpEntity entity = response.getEntity();

if (entity != null) {

    InputStream instream = entity.getContent();
    String result = convertStreamToString(instream);

            // Do whatever with the data here


            // Close the stream when you're done
    instream.close();

    }
}
catch(Exception e) { }

And for easily converting the stream to a string, just call this method:

private static String convertStreamToString(InputStream is) {

    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();

    String line = null;
    try {
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return sb.toString();
}
