parsing xml ... ithink the prob. is about encoding

Question

I'm making an android app. It has an XML parser. The XML is type of my api's response This is The Way I downloaded it to InputStream :

private InputStream downloadUrl(String urlString) throws IOException {
            URL url = new URL(urlString);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            String encoded;
            encoded = "Basic " + Base64.encodeToString("user:pass".getBytes(), 0);
            conn.setRequestProperty("Authorization", encoded);
            conn.setReadTimeout(10000 /* milliseconds */);
            conn.setConnectTimeout(15000 /* milliseconds */);
            conn.setRequestMethod("GET");
            conn.setDoInput(true);
            conn.connect();
            InputStream stream = conn.getInputStream();
            return stream;
        }

The XML's output if the user and pass are correct is :

<status>true</status>

if it's not :

<status>false</status>

and parser class is :

private static final String ns = null;

    public Boolean parse(InputStream in) throws XmlPullParserException, IOException {
        try {
            XmlPullParser parser = Xml.newPullParser();
            parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
            parser.setInput(in, null);
            parser.nextTag();
            return readFeed(parser);
        } finally {
            in.close();
        }
    }
    private Boolean readFeed(XmlPullParser parser) throws XmlPullParserException, IOException {

        parser.require(XmlPullParser.START_TAG, ns, "verify_account");
        while (parser.next() != XmlPullParser.END_TAG) {
            if (parser.getEventType() != XmlPullParser.START_TAG) {
                continue;
            }
            String name = parser.getName();
            if (name.equals("status")) {
                return readSta(parser);
            } else {
                skip(parser);
            }
        }
        return false;
    }
    private Boolean readSta(XmlPullParser parser) throws IOException, XmlPullParserException {
        parser.require(XmlPullParser.START_TAG, ns, "stats");
        String name = readText(parser);
        parser.require(XmlPullParser.END_TAG, ns, "stats");
        if (name == "true"){
            return true;
        }
        else {
            return false;
        }
    }
    private String readText(XmlPullParser parser) throws IOException, XmlPullParserException {
        String result = "";
        if (parser.next() == XmlPullParser.TEXT) {
            result = parser.getText();
            parser.nextTag();
        }
        return result;
    }

the problem is that the class PareXml always returns false :| but I printed the tag's value and it was "true" i tried adding spaces before and after the "true" in readSta function line 4 but it's not working :| . it seems to be an encoding problem

I tried many things but it's still not working :|

Answer 1

In your readSta method, instead of using :

if (name == "true"){
            return true;
        }

use:

if (name.equals("true")){
            return true;
        }

Try this once.
