android:在設備旋轉後,不要再執行create

請在到AndroidManifest.xml中,找到那個Activity的定義
加上這個參數:
            android:configChanges="orientation|screenSize" 

(如果是在tab host中的activity,則請在tabhost所在的activity加上這參數)

For Extjs4,如果是各別欄位設定初值的話 ,如何正確重設dirty flag ?

步驟1.在你的form panle中設定「trackResetOnLoad:true」之,
 

步驟2.
form.ffindField(....).setValue(.....);
...
...
...
...

form.setValues(form.getValues());
form.reset();   <--這時dirty flag就完成重設了

for android ,accept ssl (any host)

1.u need a trust manager

}
====================================================
2nd,u need a  SSL socket factory:
================code=====================================
import android.net.SSLCertificateSocketFactory;
import android.net.SSLSessionCache;
import android.os.Build;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.params.HttpParams;

        super(truststore);
        TrustManager tm=new _FakeX509TrustManager();
        sslContext.init(null, new TrustManager[] { tm }, null);
    }

    public NeoTechSSLSocketFactory(SSLContext context) throws KeyManagementException, NoSuchAlgorithmException, KeyStoreException, UnrecoverableKeyException {
       super(null);
       sslContext = context;
    }

    @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();
    }
}
=======================================
 3nd, u need create httpClient from the SSLSocketFacotry
======function  create HttpClient=======================
 private static HttpClient sslClient(HttpClient client) {
   try {
       X509TrustManager tm = new X509TrustManager() {
           public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
           }

           public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
           }

           public X509Certificate[] getAcceptedIssuers() {
               return null;
           }
       };
       SSLContext ctx = SSLContext.getInstance("TLS");
       ctx.init(null, new TrustManager[]{tm}, null);
       SSLSocketFactory ssf = new NeoTechSSLSocketFactory(ctx);
       ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
       ClientConnectionManager ccm = client.getConnectionManager();
       SchemeRegistry sr = ccm.getSchemeRegistry();
       sr.register(new Scheme("https", ssf, 443));
       return new DefaultHttpClient(ccm, client.getParams());
   } catch (Exception ex) {
       return null;
   }
}

====================================================

4th,now u can use it

=====================caller example==========================

     _FakeX509TrustManager.allowAllSSL();
HttpClient httpclient =  sslClient(new DefaultHttpClient());
   HttpPost httppost = new HttpPost("https://"+SERVER_ADDRESS+destPath);
                            ....其他照舊....
