How to Solve Android App Icon Showing Default in Oreo (API 26) and above

Problem: Android App Icon is not using your generated PNG images in Oreo, Pie and above

Explanation:

Using Android Studio, the IDE by default generated the use of adaptive icons in a new project. However, adaptive icons will only work for API 26 and above. So your app may be showing your generated icons blissfully until you tested on Oreo or Pie, where it seems to be defaulted back to the standard icon.

To solve the problem, you just have to delete the adaptive icons from the folder mipmap-anydpi-v26 and mipmap-anydpi by deleting the two folders.

This is because if a resource is found in mipmap-anydpi-v26, it will always take precedence if API level is 26 or more (Oreo). The next precedence is mipmap-anydpi.

So if you are not using adaptive icons, just do the above and your generated PNG icon images will be showing in Oreo onward.

Simple Steps to Use

1. Start the app to start scanning for Bluetooth devices around you. You can save specific device by clicking on the list of discovered devices, and you can change the name of the device to something you can remember.

2. Subsequently you can scan for only those you saved in your saved list. This helps to identify known devices you recorded previously.

3. The app also has another function called history. This will just record all the known devices every time you press record history. Every similar device will get their count incremented. This helps to identify devices that are always around you.

4. This app only runs in your device and does not communicate with our servers. There is no information transfer from your device out to anywhere from our app.
