C:\Users\Suresh\Desktop\niskri 1.0\app\src\main\res\layout\[login to view URL]: Error: The id "search" is not defined anywhere. [UnknownId] android:layout_below="@id/search" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Explanation for issues of type "UnknownId": The @+id/ syntax refers to an existing id, or creates a new one if it has not already been defined elsewhere. However, this means that if you have a typo in your reference, or if the referred view no longer exists, you do not get a warning since the id will be created on demand. This check catches errors where you have renamed an id without updating all of the references to it.
