Trying to use JSR 75 to access media saved under the '/home/video/' directory on the device. Using Blackbery JDK 4.6.1. Single line of code throws a 'FileSystem IO Error
' Exception. Which is, as usual, unhelpful in the extreme.
fconn = (FileConnection)Connector.open("file:///home/user/videos/"+name, Connector.READ);
Has anyone tried to do this? I can open files within my jar, but can't seem to access the media folder. I have the javax.microedition.io.Connector.file.read
permission set and my appplication is signed.
There are two kind of filesystems on BlackBerry - SDCard and store. You have to use one of them, defining it in the path. Standard directory on SDCard where video, music etc stored is "file:///SDCard/BlackBerry".
String standardPath = "file:///SDCard/BlackBerry";
String videoDir = System.getProperty("fileconn.dir.videos.name");
String fileName = "video.txt";
String path = standardPath+"/"+videoDir+"/"+fileName;
String content = "";
FileConnection fconn = null;
DataInputStream is = null;
ByteVector bytes = new ByteVector();
try {
fconn = (FileConnection) Connector.open(path, Connector.READ);
is = fconn.openDataInputStream();
int c = is.read();
while(-1 != c)
{
bytes.addElement((byte) (c));
c = is.read();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
content = new String(bytes.toArray());
add(new RichTextField(content));
