Android Studio 3.3 disallows adaptive icons for SDK version less than 26
Just upgraded from Android Studio 3.2.1 to 3.3. Previously my project - targeting SDK v28 - built without problems, now I get this build error:
- What went wrong: Execution failed for task ':app:processDebugResources'.
Android resource linking failed C:\app\src\main\res\mipmap-anydpi-v25\ic_launcher_round.xml: error: <adaptive-icon> elements require a sdk version of at least 26.
error: failed linking file resources.
Obviously, I have an <adaptive-icon> resource in the mipmap-anydpi-v25 folder.
So, which AS version handles this correctly; 3.2.1 or 3.3? Should I remove my v25 icon? I thought Lollipop had support for this type of icons...

Presumably 3.3, since adaptive icons were added in Android 8.0 (API Level 26).
Should I remove my v25 icon?
Change the directory to mipmap-anydpi-v26/, and you can still use that icon for Android 8.0+. If your minSdkVersion is below that (and I assume that it is), you will need an alternative implementation of the icon for the older devices.

Lollipop is Android 5.x, API Level 21-22. Your -v25 directory would not be used for those API levels.
