Android- remove URL percent symbols from string

Question

I have a URL that looks like this:

Liberty%21%20ft.%20Whiskey%20Pete%20-%20Thunderfist%20%28Original%20Mix%29.mp3

I'm trying to extract just the words from it. Right now, I'm using string.replace("%21", "!") for each and every %20, %29, etc. because each segment represent different characters or spaces. Is there a way to just covert those symbols and numbers to what they actually mean?

Thanks.

Answer 1

Those symbols are URLEncoded representations of characters that can't legally exist in a URL. (%20 = a single space, etc)

You need to UrlDecode those strings:
