In my Android app I am sharing one httpclient for all activities/threads. All requests are made by callling getHttpClient().execute(httpget) or getHttpClient().execute(httppost).
Is this implementation complete/correct and safe for multiple threads? Is there anything else missing i.e. Do I have to worry about releasing connections at all?
private static HttpClient httpclient ;
public static HttpClient getHttpClient() {
if(httpclient == null){
return getHttpClientNew();
}
else{
return httpclient;
}
}
public static synchronized HttpClient getHttpClientNew() {
HttpParams params = new BasicHttpParams();
ConnManagerParams.setMaxTotalConnections(params, 100);
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, "UTF_8");
HttpProtocolParams.setUseExpectContinue(params, false);
HttpConnectionParams.setConnectionTimeout(params, 10000);
HttpConnectionParams.setSoTimeout(params, 10000);
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
ClientConnectionManager cm = new ThreadSafeClientConnManager(params, schemeRegistry);
httpclient = new DefaultHttpClient(cm, params);
return httpclient;
}
This is an example of how the httpclient is used:
private void update() {
HttpGet httpget = new HttpGet(URL);
httpget.setHeader(USER_AGENT, userAgent);
httpget.setHeader(CONTENT_TYPE, MGUtils.APP_XML);
HttpResponse response;
try {
response = getHttpClient().execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null) {
// parse stuff
}
}
catch (Exception e) {
}
}
