Duplicate string literal found - Android Studio (Java)

Question

I got a problem on my Java code on Android Studio: I got this warning " Duplicate string literal found in   'com.example.xyz.MainActivity' " on my code on ConnectThread (private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb");) and on MainActivity ( UUID applicationUUID = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb"); ) subprograms. Both of them should be used for a bluetooth connection on a phone apk connection to other device. What should I do and what you recommend to me? Thanks for help!

Answer 1

This means that you have given same name to 2 variables. Variable names can not be repeated. Please look in your file if you have a duplicate variable.

Answer 2

it says that you have duplicated variable:

"00001101-0000-1000-8000-00805f9b34fb"

To avoid this warning you should extract it to the constant:

private static final String HASH = "00001101-0000-1000-8000-00805f9b34fb"

and then use HASH variable instead a literal:

UUID MY_UUID = UUID.fromString(HASH);

UUID applicationUUID = UUID.fromString(HASH);
