Hi Raveesh,

I selected the android:layout_centerHorizontal property and set that to true. That passed the challenge. When I tried passing the first task using layout_centerInParent the error gave the hint to use the first property.

I hope that helps.

Steve.

Yes, even I passed the challenge, but instead of writing two lines for centerHorizontal and centerVertical, wouldn't it be wiser to use centerInParent? Are there any known tradeoffs? Thanks a lot for your guidance!

I think that the challenge is just reiterating the topics covered in the previous videos to assist learning, rather than trying to introduce new things, perhaps. The challenge is looking for a property being set that aligns horizontally. It doesn't expressly exclude also being aligned vertically, but that's a reasonable inference. I don't know what the tests behind the scenes are looking for but it seems that the expected output is for vertical alignment not to be altered within task 1.
