Java/ J2ME mobile orbiter

[sambuca]

Hi

Just a quick update. I've implemented a new datagrid/list for the JavaMO. This is the same datagrid that the original PlutoMO uses. Since I've never used the PlutoMO, I can't know for sure if is 100% identical, but I think it should be at least close. I trust you to give me feedback  Anyway, its much better than the previous device-specific list...

Additionally, I've started to add some support for the VMC stuff. No much yet, but more will come. Most obvious is the startup screen. It's what I think is the first screen on the PlutoMO (keep in mind, I've only studied the code, not used it). From here you can currently view the about, the log and exit the application. In the future you will see a list of the VMC items on the phone, and be able to delete them and start them.

After a few seconds the MO should receive a connection from the bluetooth dongle, and it will display the orbiter as before.

The new JavaMO.jar can be downloaded from the same location as before.

best regard,
sambuca

guy you rock! I already lost confidence that we will find a skilled person to continue this work!! If you ever come to Berlin, send me a PM, we'll have some nice drinks :-)

sambuca, if you'd like, i can work with you on the vmc bits.

I have a copy of VIPDesign for windows that you can run to see what's possible.

hari:Thanks for the offer, I'll keep that in mind. :-)

tschak909: It is quite possible that I might need some help when I really start to dig into the vmc. For the datagrid, it was quite easy to write the code using the original as a template. But I am sure that the vmc stuff is more complicated.
  I haven't made a plan for what to do next, but I think I still have some coding to do before starting to touch the vmc itself. Still need to make saving and loading of VMC files on the phone work, and there is also more BD commands to implement.

Anyway, I'll just have to see what the holidays bring this year, time to work on the MO or family stuff

Another update;

I've made another small improvement to the JavaMO. The image quality and signal strength screens are now working. The MO still starts with a default quality of 30, but I'm thinking about a better way. Maybe we should detect if the MO supports JPG and if not, we must use quality 100 (PNG), but if it does, we can start with the 70 setting, which seems to be default for all MOs.

On a side note, it is possible to compress PNGs also isn't it? If the BD Orbiter could send us PNG images instead, we could allow all phones to use the quality setting...

Key press handling has also been improved, it should now correctly detect and send keys in the "repeated key" list. For instance volume up and down keys in most media screens. It might need some sort of control on how many commands is sent, though, now it sends a bunch of commands, and from the logs on the MD I can see it still receiving them long after the key was released.
How does the PlutoMO fare in this regard?

Probably missed some things in this short summary. Anyone interested should check the svn 

The latest version is available at http://hob.dyndns.org/javamo/. I would appreciate some test reports :-)

Hi,

I am into testing some things before i setup a linuxmce in my new house. And right now I am trying to get my HTC Diamond into talking to linuxmce. But unfortunatly the JavaMO from hari (vt100.at/javamo) tells me java.lang.NoClassDefFoundError when I am starting it. And the newer version from Sambuca tells med that the application is not developed to work with this phone.

It runs Window Mobile 6.1 with Esmertec's Jbed Java VM. If that helps.

Thanks for spending your time working on LinuxMCE

Viking,

I've seen reports around the Internet that this phone don't support bluetooth access from Java (jsr-82). Maybe thats the problem with hari's version. Don't know about my version though. I think I kept the application within the MIDP 2.0 spec, so you should make sure that the phone supports that. But it might just be that it's the bluetooth support that triggers the error, although it should have displayed the same message as hari's version.

best regards,
sambuca

you need j2me midp2.0/cldc1.1 and jsr082 for both versions of the javamo. Is your Java VM a real J2ME VM with all those features?

Hey guys,

tried to install the new version on N80, but it shouts: "Program not compatible with phone"

However I was able to install one of the former versions last time. What could that reason be?

thanks

Hi IF,

Please try again, it should work now.

Seems I didn't fix a problem with a typo in the JavaMO.jad file properly the last time. 

br,
sambuca

[_if_]

thanks alot! I tried it, but now it says: "unvalid jar data" ...even if I open the .jad file it throws the same error message.

the updated file is in the same link as above, right?

thanks for any help

I had to edit the manifest in the either the jar or jad to match each other to get it to work with my phone. If i remember properly, the cldc in one of them was incorrect and one other thing. Bottom line they need to match;)

[sambuca]

ok, not my day, apparently.

I used a new jad file when I fixed the previous problem (wrong CLDC version, as socabomb mentions), and the new file has different JAR file size than the published one... I'll try to get it right the first time around next time

[hari]

that whole manifest/jad is crap. I'd prefer a single package with a single manifest in it :-)

br Hari

ps: sambuca: keep up the great work!

Hallo Hari and Sambuca,

I now tried the new version from sambuca and it now said the same as hari's version.
I actually remeber searching the internet befor getting the phone and it was mentioned in the sprecs that it would support jsr-82. But if it doesn't that would be shitty I will have to look if there are solutions for this ...

Thanks for now and keep up the good work both of you
