In this Firebase App Indexing sample code for stickers and sticker packs there seem to be two different methods to associate a "Sticker" with a "StickerPack".
In method 1, you create a StickerPack and then associate the stickers with it by calling put using a key named "hasSticker":
Method #1
new Indexable.Builder("StickerPack")
.setName("Snoopy Pack")
.setImage("content://sticker/pack/canonical/image")
// see: Support links to your app content section
.setUrl("http://sticker/pack/canonical/url/snoopy")
// Set the accessibility label for the sticker pack.
.setDescription("A sticker pack of Snoopy")
.put("hasSticker",
new Indexable.Builder("Sticker")
.setName("Hey")
.setImage("http://link/to/the/image/hey")
.setDescription("A Snoopy hey sticker.")
.build(),
new Indexable.Builder("Sticker")
.setName("Bye")
.setImage("http://link/to/the/image/bye")
.setDescription("A Snoopy bye sticker.")
.build())
.build());
In method 2, you create a Sticker and then associate the StickerPack with it by calling put using a key named "isPartOf":
Method #2
new Indexable.Builder("Sticker")
.setName("Hey")
.setImage("http://www.snoopysticker.com?id=1234")
// see: Support links to your app content section
.setUrl("http://sticker/canonical/image/hey")
// Set the accessibility label for the sticker.
.setDescription("A sticker for hi")
// Add search keywords.
.put("keywords", "hey", "snoopy", "hi", "hello")
.put("isPartOf",
new Indexable.Builder("StickerPack")
.setName("Snoopy Pack"))
.build())
.build()),
To muddy the waters, in this official google firebase quickstart for app-indexing on github they go to some trouble use both the hasSticker and isPartOf methods. And to make it more interesting, "isPartOf" has changed its name to just "partOf":
indexableStickerBuilder.put("keywords", "tag1_" + i, "tag2_" + i)
// StickerPack object that the sticker is part of.
.put("partOf", new Indexable.Builder("StickerPack")
.setName(CONTENT_PROVIDER_STICKER_PACK_NAME)
.build());
Is there any benefit to using both "hasSticker" and "isPartOf" when defining a Sticker and its relationship to a StickerPack -- or is just one of them good enough?
And which is correct: "partOf" or "isPartOf" -- or are both correct?
