Writing a multi-times ringing alarm clock for Xpressmusic 5130

[lucky7456969]

Hello,
I want to establish a thread to poll the time on the phone. One the time is up, it goes to ring.
But as usual, my concern is the power consumption. Is this phone smart enough to manage power for me?

I run this JAD file, I get

Xdescriptor: JAD file doesn't exist.

Using Nokia IDE for Java ME (Eclipse) v1

Thanks
Jack

If you run code to poll, the phone will let you run code that polls, and there is no such intelligence in the phone where it'd know that those instructions would somehow be special and no be run to save power.

So, you shouldn't poll (or at least not frequently). A timer with a callback function is better.

Thank you petrib. What about the issue of "Xdescriptor: JAD file doesn't exist."?

What's in your .jad file? What's in the manifest file inside your .jar file? When you say "I run this JAD file", what exactly do you mean (the steps you do in order to "run" it)?

Here is where I am stuck



=> I also ran the emulator from the SDK, it says Invalid application. Delete?
=> BTW, what is a manifest?

Xdescriptor: JAD file doesn't exist.
