How to create UUID from string in android

Question

In my app, I scan low energy Bluetooth for specific service uuid 2415. To convert the string 2415 into uuid I am using UUID serviceUUID = UUID.fromString(

Answer 1

I have a feeling that your String "2415" might just have been straight-up converted from a long, because, as the others point out, "2415" is not close to resembling a UUID. If that is the case, then you should use the UUID constructor which takes two longs:

uuid = new UUID(long mostSignificant, long leastSignificant)

where you can retrieve those long values via

uuid.getMostSignificantBits() uuid.getLeastSignificantBits()

So in your case, you might do something like uuid = new UUID(2415,2415)
