Android - API 请求

我开发了一个应用程序，它也在 iPhone 上。问题出在 api 请求上。 我为所有请求设置了超时。有时会出现 30 - 60 秒的中断。 看起来这个应用程序执行了几个请求，然后就中断了，一直超时，大约 45 秒后一切正常。

不知道是服务器问题还是安卓问题。

此问题在 iOS 5 的 iPhone 上不会出现，但在 iOS 4 上也会出现。

所有请求都是 SSL，并且由于证书不受信任，我使用此类：

public class HttpSupport 
{
//********************************************
// Two methods to remove the "certificate" issue.
//********************************************

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();
    }
}

public SSLSocketFactory getSSLSocketFactory()
{
    try 
    {
        KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
        trustStore.load(null, null);

        SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
        sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        return sf;
    } 
    catch (Exception e) 
    {
        return null;
    }
}

public DefaultHttpClient 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);

        int timeoutConnection = 3000;
        HttpConnectionParams.setConnectionTimeout(params, timeoutConnection);
        // Set the default socket timeout (SO_TIMEOUT) 
        // in milliseconds which is the timeout for waiting for data.
        int timeoutSocket = 5000;
        HttpConnectionParams.setSoTimeout(params, timeoutSocket);

        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();
    }
}
