不同设备上具有相同分辨率和dpi的不同图标大小

Question

I'm testing my app on 2 devices - a Samsung Galaxy S3 and a Samsung Galaxy Note 2. Both have the same screen resolution and apparently both use the same xhdpi density even though the Note 2 has a considerably lower physical dpi.

My icons on the action bar look smaller on the S3 than on the Note 2. Why is this so, and how can I fix it so that it looks consistent?

Answer 1

It turns out that even though the resolutions I was using for the individual pixel densities were correct, the actual icon area within the image file had an incorrect size. I followed this guide at iconhandbook.co.uk/reference/chart/android/ and now things look consistent.
