Problem with Nokia6300 (S40)

[manojkumar.m]

Hi friends,

I have written an application which reads media file from specific drive.

I have placed the cutegirl.3gp in E:

here is the code:
fc = (FileConnection)Connector.open("file:///E:/Data/Sounds/cutegirl.3gp");
InputStream is = fc.openInputStream();

Player player = Manager.createPlayer(is,"video/3gpp");
player.prefetch();
player.realize();
player.start();

Its working fine on E61i which is S60.

when I tried to run the same code on Nokia 6300 which is S40,
it could not able to play the media file and an alert comes saying "media exception".

what could be the problem?

Please help me.

Thanks,
Manoj.

Hi Manoj,

you're getting that Exception since that path is not correct when working on S40 devices. Generally speaking, when accessing predefined folders (e.g.: photos, videos..) you should use System properties that give you their exact path, instead of using hard-coded paths like in your code.

Check this page for a full listing of related System properties:

In your case, using "fileconn.dir.tones" or "fileconn.dir.music" properties should work.

Hi jappit,

Thanks for your reply. I solved that one.

my mobile model is Nokia 6300.

But I am getting new exception,
java.lang.OutOfMemory,
javax.microedition.media.MediaException: OutOfMemoryError at Realizing

I am creating player by creating input stream and passing argument to Manager.createPlayer();

Can you please tell me why I am getting?

Thanks,
Manoj.

Hi Manoj,

from OutOfMemoryError JavaDocs:

Thrown when the Java Virtual Machine cannot allocate an object because it is out of memory, and no more memory could be made available by the garbage collector.

So, your 3gp file is probably too big to be handled by Java heap memory available on your test device.

Hi jappit,

actually, my device has free memory of 50MB.
Still it gives the exception.

if I play the song directly by taking the url of the media file,
then it is playing.
ex:
url = "file:///E:/Data/sounds/cutegirl.3gp";
Player p = Manager.createPlayer(url);

but when I use inputstream I am getting exception for only 6300.
But not on E61i.
ex:
fc = (FileConnection)Connector.open(url);
InputStream is = fc.opneInputStream();
Player p = Manager.createPlayer(is,"video/3gpp");
player.start();--->getting exception on Nokia 6300.

Thanks,
Manoj.

Hi Manoj,

Java heap memory is not the same as memory available on the device. You should refer to device specifications to spot out the Java heap memory for each of them.

As for Nokia 6300, as you can see on its specifications page:

http://www.forum.nokia.com/devices/6300

it has an Heap size of 2MB, while instead Nokia E61i has an unlimited heap size.

As for your memory problem, it is a known issue on S40 2nd and 3rd edition devices:
