If you are using android:src in xml during runtime this will show up on the app, whereas if you use tools:src in xml it will show only on the preview of Android studio and not on the runtime of the app.
 
    
    If you start to use support library (vectorDrawables.useSupportLibrary = true), change tools:src to tools:srcCompat
