如果不需要验证服务器端证书，直接照这里做。

    public class Demo extends Activity {         /** Called when the activity is first created. */             private TextView text;         @Override         public void onCreate(Bundle savedInstanceState) {             super.onCreate(savedInstanceState);             setContentView(R.layout.main);             text = (TextView)findViewById(R.id.text);             GetHttps();         }                  private void GetHttps(){                 String https = " https://800wen.com/";                 try{                         SSLContext sc = SSLContext.getInstance("TLS");                         sc.init(null, new TrustManager[]{new MyTrustManager()}, new SecureRandom());                         HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());                         HttpsURLConnection.setDefaultHostnameVerifier(new MyHostnameVerifier());                        HttpsURLConnection conn = (HttpsURLConnection)new URL(https).openConnection(); 
                        conn.setDoOutput(true);                         conn.setDoInput(true);                        conn.connect();                                                  BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));                  StringBuffer sb = new StringBuffer();                  String line;                  while ((line = br.readLine()) != null)                          sb.append(line);                                                  text.setText(sb.toString());                                         }catch(Exception e){                         Log.e(this.getClass().getName(), e.getMessage());                 }                        }                  private class MyHostnameVerifier implements HostnameVerifier{                     @Override                     public boolean verify(String hostname, SSLSession session) {                            // TODO Auto-generated method stub                             return true;                     }         }             private class MyTrustManager implements X509TrustManager{                     @Override                     public void checkClientTrusted(X509Certificate[] chain, String authType)                                     throws CertificateException {                             // TODO Auto-generated method stub                                                 }                    @Override                     public void checkServerTrusted(X509Certificate[] chain, String authType)                                     throws CertificateException {                            // TODO Auto-generated method stub                                                }                    @Override                     public X509Certificate[] getAcceptedIssuers() {                             // TODO Auto-generated method stub                             return null;                    }                }       }

如果需要验证服务器端证书（这样能够防钓鱼），我是这样做的，还有些问题问大牛：
a. 导出公钥。在浏览器上用https访问tomcat，查看其证书，并另存为一个文件(存成了X.509格式：xxxx.cer)
b. 导入公钥。把xxxx.cer放在Android的assets文件夹中，以方便在运行时通过代码读取此证书，留了两个问题给大牛：

    AssetManager am = context.getAssets();     InputStream ins = am.open("robusoft.cer");     try {             //读取证书             CertificateFactory cerFactory = CertificateFactory.getInstance("X.509");  //问1             Certificate cer = cerFactory.generateCertificate(ins);             //创建一个证书库，并将证书导入证书库             KeyStore keyStore = KeyStore.getInstance("PKCS12", "BC");   //问2             keyStore.load(null, null);             keyStore.setCertificateEntry("trust", cer);             return keyStore;     } finally {             ins.close();     }     //把咱的证书库作为信任证书库     SSLSocketFactory socketFactory = new SSLSocketFactory(keystore);     Scheme sch = new Scheme("https", socketFactory, 443);     //完工     HttpClient mHttpClient = new DefaultHttpClient();     mHttpClient.getConnectionManager().getSchemeRegistry().register(sch);

问1：这里用"PKCS12"不行
答1：PKCS12和JKS是keystore的type，不是Certificate的type，所以X.509不能用PKCS12代替

问2：这里用"JKS"不行。

答2：android平台上支持的keystore type好像只有PKCS12，不支持JKS，所以不能用JKS代替在PKCS12，不过在windows平台上是可以代替的
