    if (statusCode == 200) { // Status OK
    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("Log", "Failed to download result..");
    }
    } catch (ClientProtocolException e) {
    e.printStackTrace();
    } catch (IOException e) {
    e.printStackTrace();
    }
    return builder.toString(); }}

You can directly passed username and password into string like: String url = "http://www.internet.com/api?UserName=YourUsername&Password=yourpassword" or another way is pass username and password into Headers like: request.addHeader("UserName", username); request.addHeader("Password", password); — M D

Assuming your target API requires Basic Authentication, you need to add the credentials to the request as follows:

String user = "username";
String pwd = "password";
httpGet.addHeader("Authorization", "Basic " + Base64.encodeToString((user + ":" + pwd).getBytes(), Base64.NO_WRAP));

I have a basic sandman REST API set up in front of my MySQL db, and doing curl http://user:[email protected] would work in terminal, but not in my Android app. This answer helped me. Thanks!

You need to import => import org.apache.commons.codec.binary.Base64

Just a tip, use AsyncTask instead of deactivating StrictMode.

Try passing your credentials to the HTTP client setting your credential provider, specifying you want to use them just for that server:

String url = "http://flightxml.flightaware.com/json/FlightXML2/";
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
StrictMode.ThreadPolicy policy = new StrictMode.
ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy); 

TextView txt1 = (TextView)findViewById(R.id.textView1);

String result  = HttpGet(url);
txt1.setText(result);
               }

// Connect Http Get //
public String HttpGet(String url) {
StringBuilder builder = new StringBuilder();
HttpClient client = new DefaultHttpClient();

// Set up the credential provider for that server and port
CredentialsProvider credentials = new BasicCredentialsProvider();
credProvider.setCredentials(new AuthScope("flightxml.flightaware.com", 80),
    new UsernamePasswordCredentials("username", "password"));

// and tell your client to use it
client.setCredentialsProvider(credentials);

// then fetch your data
HttpGet httpGet = new HttpGet(url);

try {
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) { // Status OK
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("Log", "Failed to download result..");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return builder.toString(); }}
