 STOP! It looks like you want to suppress some lint errors:
 - Have you tried identifing the offending patch?
   Ask the author for a fix and/or revert the patch.
 - It is preferred to add suppressions in the code instead of
   sweeping it under the rug here. See:

Are you sure the suppression is needed? It seems downloads_big.xml is not in the
list while it is also a vector drawable.

Maybe I'm missing something but downloads_big.xml is right above these new
items.
