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..
