Question

Edit: “hello” has been deleted. So, hello.

By reaching an URL, I should get a string as response. So I borrowed a part of code on this website and adapted in a method to get my string into a variable. Unfortunatelly, the “Try” block is skipped and the returned string is “*“. What do I have misunderstood something about this script ?

Is the variable “response” what I should get as a response, or something else ?

Thanks in advance.

    private String getMessages() {
    String response = "***";
    try {
        HttpClient client = new DefaultHttpClient();  
        String getURL = "http://***.com/message/";
        HttpGet get = new HttpGet(getURL);
        HttpResponse responseGet = client.execute(get);  
        HttpEntity resEntityGet = responseGet.getEntity();  
        if (resEntityGet != null) {  
            // do something with the response
            response = EntityUtils.toString(resEntityGet);
            Log.i("GET RESPONSE", response);
        }
    } catch (Exception e) {
        e.printStackTrace();

    }

    return response;
}

I don’t know if this works correctly but this is the basic idea what you must do

StringBuilder builder = new StringBuilder();
InputStream content = entity.getContent();
                    BufferedReader reader = new BufferedReader(new InputStreamReader(content));
                    String line;
                    while ((line = reader.readLine()) != null) {
                        builder.append(line);
                    }
String response = builder.toString();

UPDATE:

This is a short snipped of my code, which is working without problems:

int statusCode = mResponse.getStatusLine().getStatusCode();
                    InputStream is = null;
                    StringBuilder stringBuilder = new StringBuilder();
                    if (statusCode == HttpStatus.SC_OK) {
                        HttpEntity entity = mResponse.getEntity();
                        if (entity != null) {
                            try {
                                is = entity.getContent();
                            } catch (IllegalStateException e) {
                                e.printStackTrace();
                            } catch (IOException e) {
                                e.printStackTrace();
                            }
                            byte[] buffer = new byte[1024];
                            int length;
                            try {
                                while ((length = is.read(buffer)) > 0) {
                                    stringBuilder.append(new String(buffer, 0, length));
                                }
                            } catch (IOException e) {
                                e.printStackTrace();
                            }
                        }
                    }

by the way the buffered reading is the best solution you can choose, but I dont really think thats your problem, as I have noticed before the HTTPEntity must not be null, so I assume there is something wrong with the HTTPRequest, maybe try to check the request-results using fiddler.
