getHintAmbientBigPicture
Deprecated
This feature is no longer supported.
Get a hint that this notification's BigPictureStyle (if present) should be converted to low-bit and displayed in ambient mode, especially useful for barcodes and qr codes, as well as other simple black-and-white tickets.
Return
true if it should be displayed in ambient, false otherwise otherwise. The default value is false if this was never set.
