android - How to send an image to Chromecast using NanoHTTPD -
i want serve file, image example, chromecast. used nanohttpd can reach content via url , here code use url:
private class webserver extends nanohttpd { public webserver() { super(8080); } @override public response serve(string uri, method method, map<string, string> header, map<string, string> parameters, map<string, string> files) { file rootdir = environment.getexternalstoragedirectory(); file[] fileslist = null; string filepath = ""; if (uri.trim().isempty()) { fileslist = rootdir.listfiles(); } else { filepath = uri.trim(); } fileslist = new file(filepath).listfiles(); string answer = "<html><head><meta http-equiv=\"content-type\" content=\"text/html; charset=utf-8\"><title>sdcard0 - tecno p5 - wifi file transfer pro</title>"; if (new file(filepath).isdirectory()) { (file detailsoffiles : fileslist) { answer += "<a href=\"" + detailsoffiles.getabsolutepath() + "\" alt = \"\">" + detailsoffiles.getabsolutepath() + "</a><br>"; } } else { } answer += "</head></html>" + "uri: " + uri + " \nfiles " + files + " \nparameters " + parameters + " \nheader "; return new nanohttpd.response(answer); } } this way can url "192.168.x.xx:8080/image.gif". create regular mediainfo url:
private void startvideo() { mediametadata mediametadata = new mediametadata( mediametadata.media_type_photo ); mediametadata.putstring( mediametadata.key_title, getstring( r.string.titulo_video ) ); mediainfo mediainfo = new mediainfo.builder( getstring( r.string.video_url ) ) .setcontenttype( getstring( r.string.content_type_gif ) ) .setstreamtype( mediainfo.stream_type_buffered ) .setmetadata( mediametadata ) .build(); try { mremotemediaplayer.load( apiclient, mediainfo, true ) .setresultcallback( new resultcallback<remotemediaplayer.mediachannelresult>() { @override public void onresult( remotemediaplayer.mediachannelresult mediachannelresult ) { if( mediachannelresult.getstatus().issuccess() ) { mvideoisloaded = true; mbutton.settext( getstring( r.string.pause_video ) ); } } } ); } catch( exception e ) { } } where <string name="video_url">http://192.168.1.38:8080/sdcard/logo_etsiit.gif</string> url got before, nothing happens when try cast image.
is possible serve file directly mediainfo without having copy , paste url web browser?
tell me if more code needed.

public class webserver extends nanohttpd { fileinputstream fileinputstream; public webserver(){ super(8080); } @override public response serve(string uri, method method, map<string, string> header,map<string, string> parameters, map<string, string> files) { string mediasend=getextension(chosenfile); fileinputstream fis = null; try { fis = new fileinputstream(environment.getexternalstoragedirectory() + "/" + chosenfile); } catch (filenotfoundexception e) { e.printstacktrace(); } return new nanohttpd.response(etsiit.etsiitcast_def.nanohttpd.response.status.ok,mediasend,fis); } } i added code oncreate:
//get ip of device running nanohttpd server wifimanager wifimanager = (wifimanager) getsystemservice(wifi_service); wifiinfo wifiinfo = wifimanager.getconnectioninfo(); int ipaddress = wifiinfo.getipaddress(); ipdevice=string.format("http://%d.%d.%d.%d:8080",(ipaddress & 0xff),(ipaddress >> 8 & 0xff),(ipaddress >> 16 & 0xff),(ipaddress >> 24 & 0xff)); // start webserver mediaserver = new webserver(); try { mediaserver.start(); } catch(ioexception ioe) { log.d("httpd", "the server not start."); }
i found solution problem: had change mediainfo mediainfo = new mediainfo.builder( getstring( r.string.video_url ) )to mediainfo mediainfo = new mediainfo.builder(ipdevice) ipdevice phone ip address (e.g. http://192.168.1.40:8080).
