Is @TargetApi annotation just for one Api level or above?

Question

I am using @TargetApi(23) in my app.

@TargetApi(23)     @Override     public void onAttach(Context context) {         super.onAttach(context);         onAttachToContext(context);     }       @SuppressWarnings("deprecation")     @Override     public void onAttach(Activity activity) {         super.onAttach(activity);         if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {             onAttachToContext(activity);         }     }      protected void onAttachToContext(Context context) {      } 

But i can not understand something: @TargetApi(23) annotation's mean "just for Api level 23" or "for Api level 23 and above" ? For example if Api level of device 24, is onAttach(Context context) method called?

Answer 1

TargetApi annotation is just for lint tool purposes and has no outcome in runtime. If you use any API methods just available on 23 within your method and don't declare the TargetApi, you will just get some warnings indicating you're using API's not available in your minimum SDK version. It's your responsibility to call this method with coherence being aware of the API level it will be called from.
