Answer 1

When you get the byte[] scanRecord from BluetoothAdapter.LeScanCallback, it will include the Bluetooth LE headers, which can be variable length depending on the type of iBeacon.

Because of the variable length headers the four bytes that indicate an iBeacon advertisement (4c 00 02 15) may begin anywhere from the third byte (scanRecord[2]) up to the sixth byte (scanRecord[5]). In the latest code, the Android iBeacon Library finds the index position of the 4c 00 02 15 within the scanRecord and calls it the startByte. Everything else is at a fixed position relative to that startByte.
