UUID.fromString causing "invalid long"

I'm working on a bluetooth application in eclipse and use an UUID to create a Rfcomm socket. However the UUID cause an error, claiming my UUID is an invalid long.

To create my UUID:

final UUID APP_ID = UUID.fromString("BEBCC5EO-0519-11E1-8AF7-EA9ECB6F1004");

....but that line gives this error:

java.lang.NumberFormatException: Invalid long: "BEBCC5EO"

Also tried this with the same result:

public String identifier = "BEBCC5EO-0519-11E1-8AF7-EA9ECB6F1004";
final UUID APP_ID = UUID.fromString(identifier);

Why does eclipse believe my string is a long? Please help me solve this error. Would be most greatful!

UUID.fromString actually splits the input string at - tokens. Then decode those a separated parts as Long values.

In your case you used BEBCC5EO. instead of BEBCC5E0. Which can't be parsed as long.

Letter O in BEBCC5EO is not a valid hexadecimal number. Hexa numbers are: 

0 1 2 3 4 5 6 7 8 9 A B C D E F

"BEBCC5EO" should be "BEBCC5E0"

You had the letter "O" instead of the digit zero.
