encoding - decode string encoded in utf-8 format in android -

i have string comes via xml , , text in german. characters german specific encoded via utf-8 format. before display string need decode it.

i have tried following:

try {     bufferedreader in = new bufferedreader(             new inputstreamreader(                     new bytearrayinputstream(nodevalue.getbytes()), "utf8"));     event.attributes.put("title", in.readline()); } catch (unsupportedencodingexception e) {     // todo auto-generated catch block     e.printstacktrace(); } catch (ioexception e) {     // todo auto-generated catch block     e.printstacktrace(); } 

i have tried this:

try {     event.attributes.put("title", urldecoder.decode(nodevalue, "utf-8")); } catch (unsupportedencodingexception e) {     // todo auto-generated catch block     e.printstacktrace(); } 

none of them working. how decode german string

thank in advance.

udpdate:

@override public void characters(char[] ch, int start, int length)         throws saxexception {     // todo auto-generated method stub     super.characters(ch, start, length);     if (nodename != null) {         string nodevalue = string.copyvalueof(ch, 0, length);         if (nodename.equals("startdat")) {             if (event.attributes.get("eventid").equals("187")) {             }         }         if (nodename.equals("startscreen")) {             imageaddress = nodevalue;         }         else {             if (nodename.equals("title")) {                 // try {                 // bufferedreader in = new bufferedreader(                 // new inputstreamreader(                 // new bytearrayinputstream(nodevalue.getbytes()), "utf8"));                 // event.attributes.put("title", in.readline());                 // } catch (unsupportedencodingexception e) {                 // // todo auto-generated catch block                 // e.printstacktrace();                 // } catch (ioexception e) {                 // // todo auto-generated catch block                 // e.printstacktrace();                 // }                 // try {                 // event.attributes.put("title",                 // urldecoder.decode(nodevalue, "utf-8"));                 // } catch (unsupportedencodingexception e) {                 // // todo auto-generated catch block                 // e.printstacktrace();                 // }                 event.attributes.put("title", stringescapeutils                         .unescapehtml(new string(ch, start, length).trim()));             } else                 event.attributes.put(nodename, nodevalue);         }     } } 

you use string constructor charset parameter:

try {     final string s = new string(nodevalue.getbytes(), "utf-8"); } catch (unsupportedencodingexception e) {     log.e("utf8", "conversion", e); } 

also, since data xml document, , assume encoded utf-8, problem in parsing it.

you should use inputstream/inputsource instead of xmlreader implementation, because comes encoding. if you're getting data http response, either use both inputstream , inputsource

try {     httpentity entity = response.getentity();     final inputstream in = entity.getcontent();     final saxparser parser = saxparserfactory.newinstance().newsaxparser();     final xmlhandler handler = new xmlhandler();     reader reader = new inputstreamreader(in, "utf-8");     inputsource = new inputsource(reader);     is.setencoding("utf-8");     parser.parse(is, handler);     //todo: data handler } catch (final exception e) {     log.e("parseerror", "error parsing xml", e); } 

or inputstream:

try {     httpentity entity = response.getentity();     final inputstream in = entity.getcontent();     final saxparser parser = saxparserfactory.newinstance().newsaxparser();     final xmlhandler handler = new xmlhandler();     parser.parse(in, handler);     //todo: data handler } catch (final exception e) {     log.e("parseerror", "error parsing xml", e); }

here sample of complete request , response handling:

try {     final defaulthttpclient client = new defaulthttpclient();     final httppost httppost = new httppost("http://example.location.com/myxml");     final httpresponse response = client.execute(httppost);     final httpentity entity = response.getentity();      final inputstream in = entity.getcontent();     final saxparser parser = saxparserfactory.newinstance().newsaxparser();     final xmlhandler handler = new xmlhandler();     parser.parse(in, handler);     //todo: data handler } catch (final exception e) {     log.e("parseerror", "error parsing xml", e); } 

update 2

as problem not encoding source xml being escaped html entities, best solution (besides correcting php not escape response), use apache.commons.lang library's handy static stringescapeutils class.

after importing library, in xml handler's characters method put following:

@override public void characters(final char[] ch, final int start, final int length)      throws saxexception {     // variable hold correct unescaped value     final string elementvalue = stringescapeutils.         unescapehtml(new string(ch, start, length).trim());     [...] } 

update 3

in last code problem initialization of nodevalue variable. should be:

string nodevalue = stringescapeutils.unescapehtml(     new string(ch, start, length).trim());
