Solution

Your Icon must feel the google requirements. Google has rules for App Icons. Look below-

Final size: 512px x 512px
Format: 32-bit PNG
Color space: sRGB
Max file size: 1024KB
Shape: Full square – Google Play dynamically handles masking. Radius will be equivalent to 20% of icon size.
Shadow: None – Google Play dynamically handles shadows.

Check the official docs for more info: Google Play icon design specifications

Edit: You have to add PNG file to all mipmap folder with name ic_launcher.png. That will create the launcher icon for your app.
