I want to serve a file, an image for example, to Chromecast. I used nanoHTTPD so I can reach the content via url and here is the code I use to get the 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()) {
for (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 I can get the url like "192.168.X.XX:8080/image.gif". Then I create a regular MediaInfo for this 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> is the url I got before, but nothing happens when I try to cast the image.
Is it possible to serve the file directly to the MediaInfo without having to copy and paste the url from a web browser?
Tell me if some more code is needed.

When I select the image from my web browser all I can see is:
uri: /sdcard/logo_etsiit.gif files {} parameters {} header
EDIT: I solved the problem with the WebServer class, now I can see the image or PDF selected in my web browser
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 also added this code to onCreate:
//Get the ip of the 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 the webserver
mediaserver = new webserver();
try {
mediaserver.start();
} catch(IOException ioe) {
Log.d("Httpd", "The server could not start.");
}
I found the solution to my problem: I just had to change MediaInfo mediaInfo = new MediaInfo.Builder( getString( R.string.video_url ) )to MediaInfo mediaInfo = new MediaInfo.Builder(ipdevice) where ipdevice is my phone ip address (e.g. http://192.168.1.40:8080).
