Question

Difference(s): android:src and tools:src?

If any, when is it considered proper to use tools:src over android:src?

Answer 1

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.
