Im making a quiz app, and want this bulb image to be present throughout.

I tried adding an ImageView in the layouts, got it to show on the preview, 
But when I run the app, image is not shown.

I tried changing the XML code from 
`app:srcCompat="@drawable/bulb"` to `android:src="@drawable/bulb"`
(crashed my app) 

```
