Android studio doesn't warning newapi. Why?

Issue

My Android Studio version:

• version: 4.2.2
• Settings->Inspections-> Calling new methods on older versions: DID CHECK (severity: error)

My project:

• compileSdkVersion 30
• minSdkVersion 21
• targetSdkVersion 30

My snippet code:

myActivity.getWindowManager().getCurrentWindowMetrics();

Method getCurrentWindowMetrics() of class WindowManager is ONLY available on Android 11 (see here: https://developer.android.com/reference/android/view/WindowManager#getCurrentWindowMetrics())

My question:

why don't Android Studio warn me about using new method:getCurrentWindowMetrics on older OS?

Solution

This bug happens when using navigation-fragment-ktx library version 2.4.x. It's fixed in recent versions, see a bug report.
