How to use the Nearby Sharing slice

SharingSlice.kt

val sliceUri = Uri.parse("content://com.google.android.gms.nearby.sharing/scan")
val sliceManager = SliceViewManager.getInstance(context)
sliceManager.registerSliceCallback(sliceUri, slice -> {
    for (targetItem in slice.items.reversed()) {
      // Each row containing a target has the hints LIST_ITEM and ACTIVITY.
      if (!(targetItem.format == SLICE && targetItem.hints.containsAll(listOf(LIST_ITEM, ACTIVITY)))) {
        continue
      }
      val targetSlice = targetItem.slice
      var deviceName: String? = null
      var action: PendingIntent? = null
      var profileIcon: IconCompat? = null

      for (item in targetSlice.items) {
        // The slice item of the target's device name contains the TITLE hint.
        if (item.format == TEXT && item.hints.contains(TITLE)) {
          deviceName = item.text.toString()
        }
        // The slice item of the target action contains the SHORTCUT and TITLE hints.
        if (item.format == ACTION && item.hints.containsAll(listOf(SHORTCUT, TITLE))) {
          action = item.action

          val iconSlice: Slice? = item.slice
          if (iconSlice != null) {
            for (iconitem in iconSlice.items) {
              // The target's icon is indicated by the IMAGE slice item format and the NO_TINT hint.
              if (iconitem.format == IMAGE && iconitem.hints.contains(NO_TINT)) {
                profileIcon = iconitem.icon
              }
            }
          }
        }
      }
      // Returns null if the data parsed from the slice is incomplete.
      if (deviceName == null || action == null || profileIcon == null) {
        continue
      }
    }
})
