Android: 50dip is different size on different devices?
<p>My understanding of the density independent pixel, is that it will render as the same size regardless of the screen dpi and dimensions.  I created an image button of with and height of 50dip.  On my medium dpi Samsung Galaxy Tab, this button measures about 10mm x 10mm (measured with a ruler.  On my large, hdpi Acer Iconia Tab, the button measures about 7mm x 7mm.  I would have expected the two buttons to have the same actual size.  Am I doing something wrong, or is my understanding incorrect?</p>
