Question: If I run this query:

```
FOR i IN [
    my_collection[*].my_prop,
    my_other_collection[*].my_prop,
    ]
RETURN i

```

I get this error:

> 
> Query: AQL: collection not found: my\_other\_collection (while parsing)
> 
> 
> 

It's true that 'my\_other\_collection' may not exist, but I still want the result from 'my\_collection'.
How can I make this error non-blocking ?

Answer: 
You should use `app:layout_constraintBottom_toBottomOf` only in `ConstraintLayout`. You can try to use inside of `FrameLayout`
then `android:gravity = "bottom"` in your LinearLayout.
Wrap you FrameLayout in a ConstraintLayout or change the FrameLayout to ConstraintLayout
