Can someone tell me whats the best size of an app icon that should work across different blackberry devices with different resolutions.

Hi,

I think it is best to tailor your app icon per device model as per these guidelines based on os 7.0 devices

hi suhelskype,

Thanks for the reply . But how can you have appicon of multiple resolutions for the same build.. 

[Shraddha]

I am not sure if this helps you- Include images of multiple resolutions in your build and pick up the correct images programmatically based on the resolution you want..

[SandeepKumar]

we can set the app icon programatically when the app start but what about when the app is not running.... Used this concept for the images used inside the application..

If it is essential for you to have the perfect icon all the time, create an autostart alternate entry that sets the icon.

My experience is (might be that RIM is killing me for this statement) that when you create an AppIcon that have a size of 128px by 128px that this will be rendered on all devices more or less acceptable.

Of course all the devices needs to resize the actual image so that it will fit on the home screen - but the home screen implementation of RIM does a great job on this. Yes of course it does not come with build in photo shop like abilities - but the scaling of my AppIcons is really at a very acceptable level.

So when you do not have device dependant CODs (build) and want to use one build for all devices (from OS7 to OS4.x) - then honestly try a 128 x 128 image.

Does 128x128 look good on a device?

All my apps use 92x92 as per OS7.0 guideline. It still looks good on OS 5 devices

Yes - 128 by 128 px [without any borders/padding] - just use the full image width...
