HTTP Get Android with Basic Auth
I am new to REST services and I have been looking for a few hours on the internet ...
I have a REST service url that returns JSON data to me . Login (username and password) basic auth . I'm looking for a simple library / code snippet that allows me to inject uri, username and password and return a JSON string.
Any help would be appreciated!

Maybe you can try something like this:
StringBuilder builder = new StringBuilder();
HttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("YOUR WEBSITE HERE");
// Add authorization header
httpGet.addHeader(BasicScheme.authenticate( new UsernamePasswordCredentials("user", "password"), "UTF-8", false));
// Set up the header types needed to properly transfer JSON
httpGet.setHeader("Content-Type", "application/json");
try {
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(content));
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
} else {
Log.e(ParseJSON.class.toString(), "Failed to download file");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
As for writing JSONObject, check out this code snippet:
public void writeJSON() {
JSONObject object = new JSONObject();
try {
object.put("name", "Jack Hack");
object.put("score", new Integer(200));
object.put("current", new Double(152.32));
object.put("nickname", "Hacker");
} catch (JSONException e) {
e.printStackTrace();
}
System.out.println(object);
}

I am using the following library ...
http://loopj.com/android-async-http/ (No binding)
This allows the following syntax to be used to set up basic authentication and run a GET request to the server ...
AsyncHttpClient client = new AsyncHttpClient();
client.setBasicAuth("username", "password");
client.get("http://myurl.com", null, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] bytes) {
String json = new String(bytes); // This is the json.
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] bytes, Throwable throwable) {
}
});
It's dead easy and the library has a lot of mainstream support from some of the big apps on Google Play like Pintrest / Instagram, etc.

Note for @erad's answer ( fooobar.com/questions/2168326 / ... )
The BasicScheme.authenticate method has been deprecated.
Instead of this:
httpGet.addHeader(BasicScheme.authenticate( new UsernamePasswordCredentials("user", "password"), "UTF-8", false));
you have to use this:
String userName = "bla bla";
String password = "top secret";
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(userName, password);
Header basicAuthHeader = new BasicScheme(Charset.forName("UTF-8")).authenticate(credentials, httpGet, null);
httpGet.addHeader(basicAuthHeader);
