  • What can Java inside cell phone do?

    hello,
    i would like to know what can Java inside my cell phone do? can it:
    1) run in a background
    2) initiate a phone call
    3) send an sms or receive an sms
    4) can it control bluetooth and to what extend
    what are things that java cannot do?
    thank you very much!

    Hi,
    J2ME apps run in sandbox mode. Things can be done using various APIs. To
    answer your specific questions:
    1) depends on the host device implementation, this is not defined by JCP
    2) AFAIK not (due to security). There might be an API however that allows you to
    do this on certain devices.
    3) Yeah, no problem. See http://java.sun.com/products/wma/
    4) Depends on APIs provided by device manufacturer. JCP defined http://www.jcp.org/en/jsr/detail?id=82.
    The things J2ME can not do are mostly features like accessing your phone
    book, use built-in camera (unless APIs are provided), floating point math
    operations, ...
    Reading J2ME related JSRs from http://www.jcp.org/ will give you the overview
    of what's defined and can be expected from all compliant phones. Other
    features may or may not be implemented.
    Hope this helps,
    Peter

  • Java micro cell phones?

    This may not be the right place to ask, but you can make something in java micro and put it on a cellphone right?

  • Minor prob - with Java on Cell phone

    I'm sorry if I'm posting this in the wrong area, please let me know. I purchased an LG8100 phone, and a SanDisk 1 gb memory card. I then downloaded songs to the memory card. On my phone, I selected the option of scanning the headset for any new songs, and usually the new songs will be picked up. However, last night when I added more songs, I got this message after the scan: java.lang.NullPointerException Code 932-B. I don't suppose someone could help me understand this? Please.

    I had the same problem and then my phone wouldn't turn on at all (got the white telus screen and thats it) so they sent it out, considered it a DOA and gave me a new phone but now the music player won't read the music files i have on my miniSD even though they worked just fine on my old phone yet it will read and transfer pix no problem....it gives me an error everytime i try to play music of: java.lang.NullPointerException Code 932-B
    i took it back to telus and they said it's my card but then why did it work in my old phone and why will it work for pix?
    can anyone help me? it's great having an mp3 phone that won't play....i miss my music at the gym
    Posted by: harmony1019
    okay so i finally decided to sit down with my phone and figure out what was going on with it and i'm sorta glad to say that after taking all 150 songs off my SDcard then putting them back on 4 at a time....i dunno where i get my patience from.....i found out that it had "issues" with 2 songs grrrr! but ya it still does the restarting thing....i guess it's a quirk that has to be lived with.
    Good luck!

  • How can you get a java program working on a cell phone?

    I was thinking of making some stuff for cell phones so i was wondering how you get a normal java program to work on cells.

    its all j2me - midlet package....Huh? The jsr-118 MID profile alone has 11 packages, one of which is javax.microedition.midlet. Notj2me - midlet.
    works best on nokia phones.Sez who? You seem to be confusing Java ME with Symbian C.
    you can use net beans midlet packge add-on.Only it's called the NetBeans Mobiliity Pack.
    Its easy to use and has lots of tutorials.Ditto for the Wireless toolkit for CLDC.
    just search on google.Yes, but with which keywords?
    @OP:
    NetBeans mobility pack comes with a short tutorial and several samples, you also need to download the latest WTK as the ver. 2.2 which comes bundled with NetBeans is just too buggy to work with. Then there are the manufacturer-specific SDKs from Nokia, Motorola, Sony Ericsson and (maybe) others.
    If and when you get started in Java ME aka j2me, it will be appropriate to post any questions you might have on the mobility forums, not here.
    Google "j2me tutorial" for many good hits.
    luck, db

  • JAVA: calling a cell phone

    How can I call a cell phone using java?
    I need it to make a call to a certain number and play a certain voice message, (and also send a text message).
    LP

    It depends which hardware you want to use, you can send sms messages via a cellphone which you have connected to your pc. Then you can use AT-commands which you have to send to the port where you have connected your phone (or gsm modul). To do this from within an application you can use javax.comm to communicate with your serial port!
    Hope it helps a little bit.

  • Java Mcro Edition and Cell Phone Applications

    Hi all, I have made a web based application and I need to add a mobile application in it.
    I use a little JME and made I simple application using it.
    I want to make a cell phone appl. which connects servlets and transfer data for both sided.
    Is JME supprots for all cell phones? or Which of cell phones brands?
    For instance;
    if I make I JME application, can I use it an apple iphone or all of cell phones?
    Can You give me some information and the way I need to follow?
    Thanks.

    It depends on how advanced the midlet will be. If standard components are used, the app should work everywhere, otherwise it need to be tested (it need to be tested always). If You need to write a midlet with Location API You first need to find a device that has this api implemented to test your application and the start writing. One importatnt thing, if a device in it's specification has written that it support Location API it doesn't have to mean that it's supported fully, some functions may not be implemented. As You can see here for instance. If You are not familiar with midlets start with a tutorial for beginners and after finishing try using more advanced APIs.

  • Java animation on a PDA, or cell phone.

    From what I have read (not recently) double buffering on cell phones
    is not possible, hence offscreen rendering (Double Buffering) is not possible. Is this still true?
    Do PDA's support double buffering?

    no its not.
    i think you have been looking at midp 1.0 specs.
    in the latest, (midp 2.0) using the javax.microedition.lcdui.game package, all this is possible, and more. it is really helpful and a lot of fun too. for example in the GameCanvas class, it renders all graphcis in an offscreen buffer till you call flushGraphics()
    i've already used it to create a minesweeper game for j2me devices. its amazing how simple life becomes with midp 2.0
    pda's are actually decades ahead of cell phones, so if mobiles support them, pda's sure do.
    (P.S. it may take a while to get midp 2.0 on all cell phones. its relatively new)

  • J2ME on cell phones questions

    Hi,
    I'm in the process of picking a project and wanted to see how doable it is. The project involves a cell phone and a Java program to use Bluetooth. This is real unknown territory for me so my questions are very simple. First does J2ME have packages/classes that allow for bluetooth communication (name)? Or is that a separate package I need to find?
    Second, can you save to files/permanent memory from an application running on a cell phone (to save some program settings etc). On the cheapest cell phone usually how little memroy is available? Also can you name some classes that allow for this in J2ME (other libraries).
    Finally how standard is all this? What's the probability that the program will run on all of the new cell phones? On all new cell phones from same manufacturer?
    Thanks.

    Hi,
    J2ME has JSR 82, that specifies BlueTooth stack. It's bundled with latest WTK releases (and netBeans 4.0 Mobility Pack as well). If it's available on device depends on HW equipment of the device of course.
    For your second Q: RMS storage is defined by MIDP 1.0 itself so yes, you can store some records. Not sure about the size I guess you can count on 8kb. The storage will be more , least I know of is 30kb on Nokia 6310, usual sizes are 1-5 Mb, smartphones use MMC cards, so the size can grow to hundreds of megs.

  • Oracle Lite on Cell phones??

    Hi,
    I have a question, the documentation and metalink said that Oracle Lite is only supported for Laptops, tablet PC, Pocket PC and Palms. However, many people is interested in using on cell phones.
    Someone knows if certain devices like Black Berry has the capability of supported it.

    The Datbase Lite client RDBMS is ported to CE, Mobile 5 and Symbian OS 7 and 8. Telephone handsets using these OS environments, Nokia, Sony Ericsson, Motorola, HTC, Samsung and others, can and do use Datbase Lite.
    Blackberry is a Java only enviroment and it is not possible to port the client database since it is written in C/C++ and RIM want allow anything but Java on their devices. We would have to re-write the client database in Java and that development effort is extreme.
    TNX,

  • Collab Subscription Emails: How to detect HTML enabled cell phone?

    We have found tremendous adoption success with using the "Subscribe Others" feature in collab. Naturally this concept rubs many folks the wrong way because often the end users don't know why they are getting these emails or what they are expected to do with them.
    To combat this problem I have been working on our email templates to include some brief FAQs at the bottom of the email that answer some of the basics: Why am I getting this email? How do I unsubscribe? etc
    There is still one issue that I am trying to resolve: Within the HTML template, is it possible to identify HTML enabled email readers?
    For example, I use a Blackberry 7250 which displays email in plaintext - when I get Collab emails they are LOADED with links to images and to the collab projects, and its frustrating to have to scroll through everything to find the meaningful stuff.
    My goal is to hide all "ugly link content" to those users that don't have HTML enabled phones - but I DO want to show it to those folks with the latest and greatest phones that can support it - such as the Blackberry Storm.
    Isolating browsers seems like it could be the way to go, but rather than coding on a per browser basis I was hoping to just be able to do some type of "if HTML enabled" check.
    Any suggestions?
    Also, if anyone is curious about how to adjust these templates feel free to ask here or email me at [email protected] and I can forward my basic manipulations.

    It turns out that there is a content type called "multipart/alternative" which can be used in cases like this.
    The content type allows you to essentially split up the content into a section for HTML and another for plain text.
    In looking at the notification templates, there are 2 for each "event". One for HTML and the other for plain text but I assume this is dependent upon the user Account Setting HTML/Plain Text and not fed into a higher level template which is set for multipart/alternative, although I have a help desk ticket setup for clarification on this issue.
    I played around with these content types and each time I crashed my notification service with a java.lang.NullPointerException.
    I'm closer to giving up on this after reading the following paragraph:
    "If email programs can recognize multipart/alternative content, they can probably also recognize HTML content.
    If they can't read HTML, they probably can't read multipart content either, which means you're going to run into the same problems with sending HTML to folks with email programs who can't understand it.
    For recipients who can read the HTML, you're sending along an extra large message with the text included for no reason." http://www.wilsonweb.com/wmt5/html-email-multi.htm
    Joel Collins wrote:
    1) you know users can select html or plain text notifications right? Its under my account.Right, but we want the email to determine it dynamically since our company uses Outlook we'd want them to get HTML when they are a desk, and plain text when they are on their cell phones.
    Joel Collins wrote:
    2) Would an easy solution be to just put the content of the email at the top and the links at the bottom?Definitely! I've already removed all of the images and some of the redundant links, and am trying to design a layout to add the remaining links either in a column right aligned or at the bottom.

  • Applet can access or not cell phone browser??

    Hi,
    I developed a applet, that is working fine for all browsers. But i tried to access that applet in my cell phone that is show exception. Should i have to install jre one cell phone or in cell phone we cant access applet. My phone is java enabled.
    Thanks and regards,
    Amit.

    But i tried to access that applet in my cell phone that is show exception. >Should i have to install jre one cell phone or in cell phone we cant access There is no phone JRE that I know of.
    applet. My phone is java enabled.I have not seen a phone that ran Applets verbatim.
    The java API that runs on all phones I have seen is usually MDIP/CLDC.
    http://java.sun.com/javame/reference/apis.jsp#api
    As such unless there is something that I don't know about,
    Applets simply won't work on your phone.
