Show error when using method with older Api

Question

I'm trying to make a library in which I want a method to be used only if it is above a certain API level.

I want the type of error shown here under putStringSet() method

I have used @TargetApi annotation but no success. Developer is still able to use that method without error.

Can you also tell what this type of error is called (in putStringSet() method)

Are you asking for android lint tools. https://android.jlelse.eu/writing-custom-lint-rules-and-integrating-them-with-android-studio-inspections-or-carefulnow-c54d72f00d30 — mudit_sen, Mar 09 '18 at 05:07
Read the link above and https://developer.android.com/studio/write/lint.html this one too to create custom lint rules for your project. :) — mudit_sen, Mar 09 '18 at 05:08

I believe you're looking for:

@RequiresApi(Build.VERSION_CODES.LOLLIPOP)

This means that only apps with min sdk of 5.0 (21?) and higher can call this. Others won't be able this method (due to a compile error), so creating and storing an error for that (specially in preferences, of all places) will be pointless.
