How can the platformRequest method defined in MIDP 2.1 JSR be used to open

  • 0

How can the platformRequest method defined in MIDP 2.1 JSR be used to open a video on a Nokia 6212 Classic?

The Forum Nokia Library states:

In Series 40, native applications are
launched with platformRequest(localapp
method. The following opens the Photos
folder in Gallery.

platformRequest(“localapp://gallery/show?folder=C:/predefgallery/predefphotos”);

Currently I have tried the following (and more):

I did make sure the resource as availble at the location given as the folder argument.

platformRequest("localapp://gallery/show?folder=C:/Gallery/Video Clips/Material.mp4");
platformRequest("localapp://gallery/show?folder=C:/gallery/video clips/material.mp4");
platformRequest("localapp://gallery/show?folder=C:/Material.mp4");
...

For testing purposes to open an image I tried,

platformRequest("localapp://gallery/show?folder=C:/Gallery/Images/Image001.jpg"); //Gallery.

platformRequest("localapp://gallery/show?folder=C:/predefgallery/predefphotos") //Failed as well :-(
...

All fail with the following error message.

ConnectionNotFoundException: Invalid URL.

It is obivious what the problem is but I cannot determine the correct way to tell the phone where a file is and what to open it with using the URL.

(I have asked the question on the Nokia Forum but to no avail. )

    Is your application signed for the Manufacturer or Operator domain? Quote from the Forum Nokia Library:

    Start local application. In Series 40,
    only allowed for manufacturer and
    operator MIDlets. In Symbian Java all
    domains work but only some
    applications are supported.

    The 6212 is a Series 40 device. Although I wouldn’t expect a ConnectionNotFoundException (rather a SecurityException), this won’t work unless you have you midlet Manufacturer/Operator signed.
