I am trying to connect to a mongodb through mongolabs REST interface in the android app I’m developing, but it is not connecting, and instead it is throwing an exception (or at least i think it is). I am not familiar with backends, so if I am making a fatal rookie’s mistake, please forgive me. This is the logcat

01-10 16:28:50.377: W/System.err(630): javax.net.ssl.SSLException: hostname in certificate didn’t match: != OR OR >01-10 16:28:50.377: W/System.err(630): at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:185) 01-10 >16:28:50.388: W/System.err(630): at org.apache.http.conn.ssl.BrowserCompatHostnameVerifier.verify(BrowserCompatHostnameVerifier.java:54)

Below is the part of MongoLabHelper class i wrote to access the database and get items like names

HttpClient client;
JSONObject db;

MongoLabHelper() throws ClientProtocolException, IOException, JSONException{
    client = new DefaultHttpClient();
    HttpGet request = new HttpGet("https://api.mongolab.com/api/1/databases/breadcrumbs/collections/crumbs?apiKey=xxxxxxxxxxxxx");
    HttpResponse response = client.execute(request);
    HttpEntity entity = response.getEntity();
    InputStream in = entity.getContent();
    String json = in.toString();
    db = new JSONObject(json); 
}

public String getName(String name) throws JSONException {
    JSONObject doc = db.getJSONObject(name);
    return doc.getString("name");               
}

and here is part the class it is used in

   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    String name = "Crumb Not Available";

    MongoLabHelper help;
    try {
        help = new MongoLabHelper();
        name = help.getName("Chipotle");
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }




    setContentView(R.layout.breadcrumb);
    TextView crumbName = (TextView) findViewById(R.id.crumb_name);
    crumbName.setText(name);

    You actually need to explicitly setup the HttpClient to handle SSL. I believe this stackoverflow thread has the information you need:

    Secure HTTP Post in Android

    I’ll copy the relevant bit of code from the thread for convenience:

    private HttpClient createHttpClient()
{
    HttpParams params = new BasicHttpParams();
    HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
    HttpProtocolParams.setContentCharset(params, HTTP.DEFAULT_CONTENT_CHARSET);
    HttpProtocolParams.setUseExpectContinue(params, true);

    SchemeRegistry schReg = new SchemeRegistry();
    schReg.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    schReg.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));
    ClientConnectionManager conMgr = new ThreadSafeClientConnManager(params, schReg);

    return new DefaultHttpClient(conMgr, params);
}
