Launch Native Image Viewer for S60

[papelboner]

I'm trying to display an image from a j2me application. Unfortunately the image is larger than can be handled by the j2me heap - so I was hoping to just call some native application to show it (e.g. what happens when I select an image from File Manager). Is there any way to do this from a j2me environment?

Where is the image? (JAR, file system, website, etc.)?

How big is it (file size, pixel dimensions, format, etc.)?

[papelboner]

Image is on the file system and is say ~1MB (large enough that using the FileConnection API's and creating an Image throws OutOfMemoryException)

Strictly, there is no provision for doing this.

You could try MIDlet.platformRequest(), using a "file:" url. platformRequest() is the main way to hand control from a MIDlet to the underlying platform. There is no guarantee that "file:" urls will be supported.

(I should add that platformRequest() is available only on MIDP-2.0 devices, and that it does not work properly on early firmware Nokia 6600s.)

That worked! Thanks for the help

[grahamhughes]

Really?? Wow!! What a guess!

lol...
this is very handy to know though, so graham, try some other guesses and place them here, maybe after all we can get a nokia to make us some coffee

MIDlet.platformRequest("Coffee");

[grahamhughes]

I've tried:

"coffee:espresso"

"coffee:capuccino"

even:

"tea:earlgrey/hot"

But no luck yet...

Hi Graham,

One last hiccup. So like I said this works great. Only problem is every time I do it I get a "allow application ... to use network to send or receive data?" My app is signed and has permissions to always allow http, file i/o, etc. Do you want to take another guess as to what permission I could apply to get this message to go away?

thanks!

I can't find any documentation that shows Nokia devices as supporting this, but I think if anything it should be:

MIDlet-Permissions: javax.microedition.midlet.PlatformRequest.url

You should keep the other permissions (like http, etc), as some Series 60 devices are not happy about platformRequest() in a signed application without these permissions set.
