Android: java.util.logging.Logger vs android.util.Log

Question

Why Android

does it support 2 different log classes that seem to support the same things?

I'm talking about:

For what I've seen over the years, every official Android documentation points to Log

, not Logger.

Even certain loggers like TimingLogger use Log

.

So why are these 2 supported?

Is there any function that can be used through Logger

that I cannot achieve through Log

?

Are there specific use cases for both?

The crossover function looks like this:

It seems that "android.util.Log" will have:

It looks like "JUL" will have:

Buffering records with java.util.logging.MemoryHandler . It is useful to tell when an error occurs SEVERE

, you can include the last 1000 records, which may be at a lower level.
Filtering records using java.util.logging.Filter . Filters without box are included in the package, but it gives more details on how to implement this behavior in android.util.Printer
XML socket support .
Socket support Sockets .
Third party support java.util.logging.Handler implementation .
