Initiating a phone call

[rolloderwikinger]

Hi, Is there any chance to initiate a phone call from within a Java MIDLet?
Thanks Roland

Hi!

Using MIDP2.0 you could use the platformRequest method with a url like "tel:<NUMBER>"

Hope this helps.

This is not available on some firmware versions eg 6600 3.42.???

Can anybody tell me which devices really support it??

thanks in advance

Hi!

Yes on the 6600 with old firmware calling platformRequest doesn't work. With 4.09 and above it work's like a charm.

platformRequest should work on any MIDP2.0 enabled device. On some devices the midlet has to terminate to actually initiate a phone call or open an url.

Thanks for the tip. Will have to check the app out on real devices to be sure.

Please tell me whats wrong in the below code...

String url = "tel:919444317263";
try{
graphics.drawString(url.toString(),5,20,Graphics.TOP|Graphics.LEFT);

midlet.platformRequest(url);

}catch(Exception e){

graphics.drawString(e.toString(),15,40,Graphics.TOP|Graphics.LEFT);
}


When the above code is seen in emulator it gives java.nullpointer.excep..

Else kindly provide me the code to initiate a call from MIDLET.

in the code above, npe can come from either graphics or midlet
and if it s thrown without being catched, it is probably the graphics.
make sure these have valid values
that's all i can with info you give

last thing, you should print the messages to system.out while running on emulator, it rediuce possibilities of mistake
