Answer 1

One more thing I wanted to add that wasn't clear for me first time I used UriMatcher.

Is that if you want to parse an HTTP url then as an AUTHORITY parameter in the addURI you need to pass the target domain name. For example:

Uri mUri = Uri.parse("http://example.com/foo");
UriMatcher sURIMatcher = new UriMatcher(UriMatcher.NO_MATCH);

// if not "example.com" below the match will always return -1 result
sURIMatcher.addURI("example.com", "/foo", 123);

int match = sURIMatcher.match(mUri);

UriMatcher Documentation doesn't cover this case and it's not clear what's this authority parameter for. Gosh if I knew that it would save me some time!
