Camera API stopped working on N95 after MIDlet was signed

[sanjk0604]

My unsigned MIDlet used to work fine on N95 with Camera APIs:

mPlayer = Manager.createPlayer("capture://video");
mPlayer.realize();
mVideoControl.getSnapshot("encoding=jpeg&width=320&height=240");

It prompted me to allow the use of camera but it started the camera and I was able to capture the photo in my J2ME application.

After java verified certified my application, it stopped working. Now when I try to start the camera using the above code, it does not start on N95.

Thanks

Hello sanjk0604,

After java verified certified my application, it stopped working. Now when I try to start the camera using the above code, it does not start on N95.

Please elaborate more: do you mean that when you try to launch your MIDlet, it doesn't start at all? If so, please view the following Known Issue article on Forum Nokia Wiki:

MIDlet starts. All the other functionality works fine....except when I try to start the Camera using CreatePlayer nothing happens.

Thanks

I think I figured out the problem....

When I added MIDlet-Permissions: javax.microedition.media.control.VideoControl.getSnapshot

it started working. However it still prompts me before starting camera even though my .jad file has a valid Java Verified signature. Could it be because my manifest file has MicroEdition-Configuration: CLDC-1.0?

Thanks

You need to manually change the API access settings for multimedia to always allowed

Here are the N95 access settings

and here are the instructions for changing the settings (they are a little hidden on S60 3rd Edition FP1 phones

Thanks. That worked. However it is too complicated for the end user. Is there a way to make these changes during app installation?

Also, it is still prompting me when I do a platform call to start the default browser. Do I need operator signature to supress that prompt?

Thanks

"Is there a way to make these changes during app installation?"

Unfortunately not.

"Also, it is still prompting me when I do a platform call to start the default browser. Do I need operator signature to supress that prompt?"

Hmmm... Have you tried changing the network settings to always allowed too?

>>>Yes - Network setting is "Always allowed". When I open HTTP connection using J2ME connection object I don't get any prompt. But when I open a phone browser using PlatformRequest I still get prompted.

Thanks
