I created following chart using Iconhandbook reference.
+----------+-----------+--------------+
| Launcher | Actionbar | Notification |
|----------|-----------|--------------|
| 48 | 24 | 22 |
| 72 | 36 | 33 |
| 96 | 48 | 44 |
| 144 | 72 | 66 |
| 196 | 96 | 88 |
+----------+-----------+--------------+
Also I found that when changing dp from 24dp to 36dp and 36dp to 48dp. Icon size increase in size + 6px.
24dp => 36dp
[12 + 6]
24px [12] 36px [18]
36px [12] 54px [18]
48px [12] 72px [18]
72px [24] 108px [36]
96px [24] 144px [36]
How these sizes change according to dp (18dp, 24dp ...). Specially notification icons?
