How to add parameters to a HTTP GET request in Android?
I use a List of NameValuePair and URLEncodedUtils to create the url string I want.
protected String addLocationToUrl(String url){
if(!url.endsWith("?"))
url += "?";
List<NameValuePair> params = new LinkedList<NameValuePair>();
if (lat != 0.0 && lon != 0.0){
params.add(new BasicNameValuePair("lat", String.valueOf(lat)));
params.add(new BasicNameValuePair("lon", String.valueOf(lon)));
}
if (address != null && address.getPostalCode() != null)
params.add(new BasicNameValuePair("postalCode", address.getPostalCode()));
if (address != null && address.getCountryCode() != null)
params.add(new BasicNameValuePair("country",address.getCountryCode()));
params.add(new BasicNameValuePair("user", agent.uniqueId));
String paramString = URLEncodedUtils.format(params, "utf-8");
url += paramString;
return url;
}
To build uri with get parameters, Uri.Builder provides a more effective way.
Uri uri = new Uri.Builder()
.scheme("http")
.authority("foo.com")
.path("someservlet")
.appendQueryParameter("param1", foo)
.appendQueryParameter("param2", bar)
.build();
