问题
I have been using using org.apache.http.client.HttpClient
to download some data from a HTTP server for past 2 years and its been working fine.
Recently we switched to HTTPS for some security reasons.This is also working fine with WiFi and High speed mobile data(3G).But most often with slow data connection(2G) My download interrupted with following stack trace.
javax.net.ssl.SSLException: Read error: ssl=0x56e63588: I/O error during system call, Connection reset by peer
at com.android.org.conscrypt.NativeCrypto.SSL_read(Native Method)
at com.android.org.conscrypt.OpenSSLSocketImpl$SSLInputStream.read(OpenSSLSocketImpl.java:690)
at org.apache.http.impl.io.AbstractSessionInputBuffer.fillBuffer(AbstractSessionInputBuffer.java:103)

at org.apache.http.conn.EofSensorInputStream.read(EofSensorInputStream.java:140)
at java.io.FilterInputStream.read(FilterInputStream.java:114)
This is how my Code Looks like :
HttpPost httpPost = new HttpPost(url);
UrlEncodedFormEntity p_entity = new UrlEncodedFormEntity(
params, HTTP.UTF_8);
httpPost.setEntity(p_entity);
response = httpClient.execute(httpPost);
DataInputStream in = new DataInputStream(response.getEntity().getContent());
String st = "";
result = new Vector<String>();
while ((st = readLine(in)) != null) {
result.addElement(st);
}

Try this:
package com.telpoo.frame.net;

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 {

}
};
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 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();
}
}
}
and use it:
URL myUrl = new URL(url);
HttpClient client = MySSLSocketFactory.getNewHttpClient(); // myHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), connectTimeout);
HttpPost post = new HttpPost(myUrl.toURI());
