Detect Buzzio

Use this to swap “Add to Buzzio” for “Added” after the user confirms.

Android — is Buzzio installed?

val installed = try {
    packageManager.getPackageInfo("com.ve.ghost", 0)
    true
} catch (_: PackageManager.NameNotFoundException) {
    false
}

Also catch ActivityNotFoundException when starting ENABLE_STICKER_PACK.

Android — is this pack added?

content://com.ve.ghost.provider.sticker_whitelist_check/is_whitelisted
    ?authority={your_authority}
    &identifier={pack_id}

Column result: 1 added, 0 not added, null invalid or Buzzio too old. You can only query packs your app provides.

iOS — can open?

UIApplication.shared.canOpenURL(URL(string: "buzzio://stickerPack")!)

Requires LSApplicationQueriesSchemes → buzzio.

Website — is this pack added?

A browser cannot query Buzzio’s whitelist provider. Always show Add to Buzzio. If the pack is already on the phone, Buzzio shows that when the user confirms.
