Android app shows default android icon in some devices

Question

I upload an app in play store.Now i got a comment that it shows default android icon in some devices (galaxy s4,nexus 5 )instead of app icon.I placed app icon in drawable-ldpi,drawable-mdpi,drawable-hdpi,drawable-xhpdi and drawable-tvdpi. Default android icon is present outside resource folder as ic_launcher-web. While testing it showed the app icon itself in galaxy s4.But when it downloaded from play store it is showing default app icon.What I should do to correct this problem?

Answer 1

Since app icon has very little impact on the system performance, I recommend that you to put a 256*256 icon in the default /res/drawable/ resource folder.
