I have followed the following steps as suggested by tutorials and other stack overflow questions:
- android:icon="@mipmap/ic_launcher" in the manifest where the app icon is named ic_launcher and all the mipmaps have been appropriately replaced on basis of resolution
- replaced all mipmap images with the the images generated from Android Asset Studio
- I have selected the appropriate files in the image asset by right clicking on res.
- I have uninstalled the old app. Rebuilt the app the ans then run
- I have invalidated cache and restarted Android Studio too
- Restarted the mobile
- Added a 512 * 512 pixel image in image asset too.
The problem I suspect is that when I launch the image asset, the default is on clipart and not on image. So everytime the app is run it may be picking up the default clipart icon.
I have also kept the app icon in the toolbar. This changes sometimes. If the app is run again it changes back to the default green android icon.
I have the new android studio 2.1. So is there some problem with it in this regards?
Rename icon file to any other name in all folders & change it in menifest.xml as well.
If it was ic_launcher, change it to any other name say app_icon in folders & menifest.xml as well.
Uninstall app & install it again.
Hope will help.
In the manifest:
android:icon="@drawable/ic_launcher"
android:logo="@drawable/ic_launcher"
In the drawable folder, I added my logo named ic_launcher having size 192*192 pixels.
This solution set me on the right track.
Have you changed in manifest file?
android:icon="@mipmap/ic_launcher" to
android:icon="@mipmap/your_app_logo_name"
