Android app icon dimensions [Not launcher icons]

Which icon size will be preferable to support different screen sizes in Android? The dimensions provided:

• ldpi-36*36 px
• mdpi-48*48 px
• hdpi-72*72 px
• xhdpi-96*96 px

worked fine for launcher icon but not for icons inside the app like ImageButtons. Can anybody help me to find out correct dimensions for ImageButtons? Thanks in advance..

You should use dp instead of px. The density-independent pixel is equivalent to one physical pixel on a 160 dpi screen, which is the baseline density assumed by the system for a "medium" density screen.

Conversion: px= dp * (dpi / 160)

For example, on a 240 dpi screen, 1 dp equals 1.5 physical pixels.

ldpi: 24*24 px NORMAL*0.75

mdpi: 32*32 px NORMAL

hdpi: 48*48 px NORMAL*1.5

xhdpi: 64*64 px NORMAL*2

manually you can calculate your sizes using the conversion from above
