java me - Is there a standard icon size and color depth for J2ME? -

There are many phones, each of which has its own icon size (for example, Nokia has 19 different sizes).

I would like to use only one icon (even if it is shown poorly).

Is there any depth of the icon size and color that is displayed in all phones?

There is no standard size, and some phones will not even show the icon if this is the exact width specified for the device And there is no height. Some phones may try to scale your icon up or down, depending on its requirement. However, you can not trust it. Another fun part of the highly fragmented mobile location :)
