@SUPERCILEX I rememeber last time you touched this code you had a reason to keep this list separate from the map in PhoneNumberUtils. Is it not exactly inverted?

@lsirac btw holding my approval on this discussion.

Ok I went through and actually just printed out the map in each case. And there is no diff in the map information:

I think if you want this to be the default you should do this in the constructor and then let every other method in the class assume that the whitelist and blacklist are setup properly.

Might also want to throw an IllegalStateException in the constructor if they're both non-null.

I'm not sure if I agree with adding an IllegalStateException. I moved that bit to the constructor though.

Add some comments here, as the assumptions took me a minute to wrap my head around (I think you're saying that at this point you know only one of whitelist or blacklist will be non-null so you're just handling the two cases for whitelist and assuming the opposite about blacklist)

I think these two variables are not used?

Removed them in my last commit.

What's the default for getStringArrayList, is it null?

Yes, it returns null if the key isn't present.

@lsirac as we talked about in chat, let's use |

I just took a look and, amazingly, it doesn't look like this will create any conflicts with #1253 |

@lsirac would it mess you up if this work was moved to doInBackground? I think originally there was a concern that the construction of this map was expensive enough to be done in the background (motivates the whole existence of this class).
If you can move it to there, then I am confident this is a safe change.

Looking around, I think that just means you will want to lazy-initialize the big static members of PhoneNumberUtils and expose getters for them.
