    Thumbs down Why are the icons for Java apps so small?

    And is there a way to make them larger?

    By the way, this is on my E61, but I am guessing it's the same on all S60 3rd Edition phones.

    TIA!

    Java apps icons are included in the Java app itself, including the display size. Most Java phones have tiny icons beside a list of the application names. So it's common for the icons to be shown as tiny on a phone that shows bigger icons. I don't think it's possible to change it without changing the actual Java source files, although even if it was the icon would just be stretched and pixelized.

    Yea, I have noticed this on all my s60v3 phones. I don't think that you can make the icon any larger. If someone knows how chime in.

    AFAIK you cant change the icon normally. You'd have to find the icon file with y-browser and replace it with something bigger. I never tried so I dont know if its a file format we can create.

    Anyhow, what I hope someone makes (which wasnt made for s60v2 anyhow) is a auto-resize app running in the background when you open java apps.

    Let me explain from a technical point of view (done mobile java app development for years):

    Traditionally phones allowed 12x12 pixel icon. Most Java apps that work across phone platforms will use a 12x12 pixel icon in their JAR file. S60 however use a much larger icon. Java apps written specifically for S60 platform will most like include such a large icon. But since a JAR file only can have one icon file, java apps normally will only come with the 12x12 pixel icon because of the limitations of non-S60 phones.

    Hope that helps....

    Edit: If you want to change it (as long as you're not breaking copyright rules):

    1. Open the JAD file in Notepad
    2. Find the filename for the icon file (normally on the first line "MIDlet-1: xxxx, ICON FILENAME, xxxx)
    3. Open the JAR file in WinZip or something and find that file.
    4. Open the icon file in a image software and resize it.
    5. Save it back into the JAR file
    6. Find the EXACT byte size of the JAR file (right click and select properties on Windows Explorer) and update the "MIDlet-Jar-Size" line inside the JAD file.
    7. Upload to your S60 phone....and voila.

    You can skip step 6 if you just upload the JAR without the JAD.

    tried this with jonnychat and didn't work, i am getting the default S60 icon in its place. Is there a specific icon size to resize too?

    Can you send me the JAD/JAR? I'll give it a shoot.

    Icon sizes (found on web):

    BlackBerry: 45x45
    Motorola Ax: 32x32
    Motorola Vx: 15x15
    Nokia Series 40: 18x18 or (more recently, since about the 6101) 29x29
    Nokia S60 (though apparently not perfect for 3rd edition): 42x29
    Sagem: 18x18
    Samsung: Many don't accept icons, but some like Z105 seem to like 29x29
    Sanyo: 24x24
    Sharp: 27x27
    Siemens: 18x18
    Sony Ericsson Px: 32x32
    Other Sony Ericssons: No icons
    Looks like a little more development since the 12x12 days

    Edit: That said....you can still have bigger or smaller icon. Too big will normally just get cropped and too small will just show up as too small.

    Check your e-mail...

    Did you save it back as a PNG file after resizing?

    thanks for your help, also i found that 75x75 looks real nice.
