Hi all,
I'm currently developing an audio streaming software application. It works by first authenticating with the audio website's authentication API. Then after receiving the session information I can request for each individual audio files. Now the trick is that the url to each of the audio file is to be only requested/accessed once only, after the first access, the ticket is expired immediatelly, and then one can only access other files within the same session.
What I'm trying to do here is to first download and buffer each of the audio file, given the valid urls. I am using tcp connection here because the audio files can be quite large(3-5 megs). (by including ";deviceside=true" in url) The problem comes when I change the connection from ready state to open state by either opening the input stream or getting the response code. The piece of code I used is:
String location = url+";deviceside=true";
HttpConnection s = (HttpConnection) Connector.open(location);
System.out.println("Response Code: "+s.getResponseCode());
System.out.println("Response Message: "+s.getResponseMessage());
long length = s.getLength();
InputStream in = s.openInputStream(); //open stream
byte[] data = new byte[256];
DataBuffer db = new DataBuffer();
int chunk = 0;
while (-1 != (chunk = in.read(data))) {
db.write(data, 0, chunk);
}
in.close();
s.close();
data = db.getArray();
// data is always empty for some reason
The response code I get is always 302 "Found", but when i open the input stream, the stream is empty. I have tried copying the individual url's for each audio file and then paste into my firefox, the files can be downloaded without a problem. The audio file would also stream fine from File>openURL in Windows Media Player. The url of the individual audio file is of the format "http://play.audiowebsite.com/user/df98sdfdf98sdfdf98sdfdf98sdf1234.mp3". One thing I've observed is that when I try to open the url in firefox, it asks me if I want to download from http://s14.audiowebsite.com/, which to me means that it has redirected me to one of its servers.
How can I download these files from my application in BlackBerry. I have been trying to solve this problem for the past 5 days, and have made very little progress. I've searched every corner of this forum. This is my last resort. All helps are appreciated.
I'm using JDE4.7 and 8820 simulator
