How to call HTTPS webservices in android

For Example :

==> First call following method.

public static void trustAllHosts() {

        X509TrustManager easyTrustManager = new X509TrustManager() {

            public void checkClientTrusted(X509Certificate[] chain,
                    String authType) throws CertificateException {
                // Oh, I am easy!
            }

            public void checkServerTrusted(X509Certificate[] chain,
                    String authType) throws CertificateException {
                // Oh, I am easy!
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }

        };

        // Create a trust manager that does not validate certificate chains
        TrustManager[] trustAllCerts = new TrustManager[] { easyTrustManager };

        // Install the all-trusting trust manager
        try {
            SSLContext sc = SSLContext.getInstance("TLS");

            sc.init(null, trustAllCerts, new java.security.SecureRandom());

            HttpsURLConnection
                    .setDefaultSSLSocketFactory(sc.getSocketFactory());

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

====> After this


For calling HTTPS webservices you need to create Custom HttpClient instead of using DefaultHttpClient.


HttpClient _httpclient = Utils.getNewHttpClient();

Following is getNewHttpClient() method :

public static HttpClient getNewHttpClient() {

try {

KeyStore trustStore = KeyStore.getInstance(KeyStore

.getDefaultType());

trustStore.load(null, null);

SSLSocketFactory sf = new MySSLSocketFactory(trustStore);

sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

HttpParams params = new BasicHttpParams();

HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);

HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

SchemeRegistry registry = new SchemeRegistry();

registry.register(new Scheme("http", PlainSocketFactory

.getSocketFactory(), 80));

registry.register(new Scheme("https", sf, 443));

ClientConnectionManager ccm = new ThreadSafeClientConnManager(

params, registry);

return new DefaultHttpClient(ccm, params);

} catch (Exception e) {

return new DefaultHttpClient();

}

}

Here we have use custom MySSLSocketFactory class, which is following.

Create new class MySSLSocketFactory.java copy following code and paste.

public class MySSLSocketFactory extends SSLSocketFactory {

SSLContext sslContext = SSLContext.getInstance("TLS");

public MySSLSocketFactory(KeyStore truststore)

throws NoSuchAlgorithmException, KeyManagementException,

KeyStoreException, UnrecoverableKeyException {

super(truststore);

TrustManager tm = new X509TrustManager() {

public void checkClientTrusted(X509Certificate[] chain,

String authType) throws CertificateException {

}

public void checkServerTrusted(X509Certificate[] chain,

String authType) throws CertificateException {

}

public X509Certificate[] getAcceptedIssuers() {

return null;

}

};

sslContext.init(null, new TrustManager[] { tm }, null);

}

@Override

public Socket createSocket(Socket socket, String host, int port,

boolean autoClose) throws IOException, UnknownHostException {

return sslContext.getSocketFactory().createSocket(socket, host, port,

autoClose);

}

@Override

public Socket createSocket() throws IOException {

return sslContext.getSocketFactory().createSocket();

}

}

Now done :) You can parse your xml now. 

Using multiple text colors in Android's textview

I had faced on issue in my past project. How to set multiple colors in single textview ? For that I have solve it using following way.

    productprice.setText(Html.fromHtml("Price" + ": "
                    + "<font color=\"#990000\">"

                    + cartList.get(position).ProductPrice + " " + "</font>"));


productprice is TextView, set   android:textColor as default color for Textview.


Hope it helps you also.

What does “xmlns” in Android XML mean?

Generally we write following line in android xml file.

xmlns:android="http://schemas.android.com/apk/res/android"

 It defines XML Namespace.

The Namespace Prefix is "android" and the Namespace URI is "http://schemas.android.com/apk/res/android"

Basically, every element (or attribute) in xml belongs to a namespace, a way of "qualifying" the name of the element.

Example :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Select + copy text in a TextView?

 Generally we can copy / paste the value from EditText by long click. It is in-build functionality of Android. Now lets say you have requirement same thing in TextView. Then you have to use registerForContextMenu.


 Like  registerForContextMenu(yourtextview);

 and your TextView will be registered for receiving context menu events.

Then You have to override onCreateContextMenu() method. Following is entire code.


 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        txtcopytext = (TextView) findViewById(R.id.txtcopytext);
        registerForContextMenu(txtcopytext);

    }

    @Override
    public void onCreateContextMenu(ContextMenu menu, View v,
            ContextMenuInfo menuInfo) {
        // user has long pressed your TextView
        menu.add(0, v.getId(), 0,
                "Copy");

        // cast the received View to TextView so that you can get its text
        TextView yourTextView = (TextView) v;

        // place your TextView's text in clipboard
        ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
        clipboard.setText(yourTextView.getText());
    }
