I want to treat a value of type Long as unsigned long. I have read that in Java 8 they added methods to do things like that. 
But when I try to use the new methods like:

```
long values = Long.parseUnsignedLong("18446744073709551615");

```

Android Studio gives me an error message like this: 

> 
> cannot resolve method parseUnsignedLong(java.lang.string)
> 
> 
> 

Can I not use the Java 8 methods on an Android system?

What would be an alternative solution?
