This is a URL ending in a question mark: https://example.com/path?

Text <https://example.com/path?>
Text (https://example.com/path?)
Text (https://example.com/path?).

This is a URL ending in a period: https://example.com/path.

Text <https://example.com/path.>
Text (https://example.com/path.)
Text (https://example.com/path.).

This is a URL containing unmatched parentheses: https://example.com/(path))

Text <https://example.com/(path))>
Text (https://example.com/(path)))
Text (https://example.com/(path))).

This is a URL containing parentheses: https://example.com/(path)

Text <https://example.com/(path)>
Text (https://example.com/(path))
Text (https://example.com/(path)).

This is a boring URL: https://example.com/path

Text <https://example.com/path>
Text (https://example.com/path)
Text (https://example.com/path).

Detecting URLs in text is great fun.

When should characters that are allowed in URLs not be considered part of it? Cases I've dealt with today: dot/period, question mark, closing parenthesis. Examples…

Irregular reminder that "@"@domain.example is a syntactically valid email address. Don't use split("@") to get the local part and/or domain.

And @k9mail is available again on Google Play.

This isn't the first time. And I'm sure the app will be available again soon.
Still, it's very annoying. You'd think a track record of 10+ years of non-malicious behavior would buy you at least another set of eyes before the app is removed.

Google removed @k9mail from the Play Store without prior notice because they objected to the following text in the app description (that has been the same for more than a year):

(People sometimes call K-9: K9, K9 Mail, K-9 Email, K9 Email, K9 E-Mail, k9mail or k9email.)

I am happy to report that my changes to the #Kotlin IDEA plugin have been merged. In the future the parameter info popup will be much more useful when using named arguments 🥳

I wrote a short blog post that explains why you might want to avoid the common 'Intent.resolveActivity() then startActivity()' pattern when targeting Android 11.

Yesterday I read through 161 comments on a feature request of another project to find out what design considerations went into their implementation. Took me almost an hour. About a third of the comments didn't add any value and could have been skipped 😞

I wrote a short blog post on why as an open source maintainer I sometimes hide GitHub issue comments.

"A Warm Welcome to ASN.1 and DER" is a really nice introduction to the topic. It also gives a good idea of why writing a DER parser is so error-prone.

I just published an update to my library SafeContentResolver. After 4 years of nobody complaining about the API I went from version 0.9.0 to 1.0.0 🐌

I wrote a blog post about bugs in an Android class that you probably don't know and probably don't need to know: android.net.MailTo.
