android backgroundTintMode  Blending mode used to apply the background tint   android backgroundTint  Tint to apply to the background  Must be a color value  in the form of  rgb   argb   rrggbb  or  aarrggbb  This may also be a reference to a resource  in the form  quot   package  type name quot   or theme attribute  in the form  quot   package   type  name quot   containing a value of this type

The backgroundTint attribute will help you to add a tint shade  to the background  You can provide a color value for the same in the form of -   rgb     argb     rrggbb   or   aarrggbb    The backgroundTintMode on the other hand will help you to apply the background tint  It must have constant values like src over  src in  src atop  etc   Refer this to get a clear idea of the the constant values that can be used  Search for the backgroundTint attribute and the description along with various attributes will be available

I won t stress much on the difference as it is already covered  but notice the below    android backgroundTint android backgroundTintMode are only available at API 21 If you have a widget that has a png vector drawable background set by android background  and you want to change its default color  then you can use android backgroundTint to add a shade to it    example   lt Button     android layout width  50dp      android layout height  wrap content      android background   android drawable ic dialog email    gt       lt Button     android layout width  50dp      android layout height  wrap content      android background   android drawable ic dialog email      android backgroundTint   color colorAccent    gt      Another example   If you try to change the accent color of the FloatingActionButton using android background you won t notice a change  that is because it s already utilizes app srcCompat  so in order to do that you can use android backgroundTint instead
