I'm trying to use a text with an HTML <b>-Tag for a compose Text(). The HTML-text is converted to a Spannable via HtmlCompat.fromHtml() and then to an AnnotatedString which applies a bold SpanStyle. See the example project: https://github.com/hardysim/htmlbtest.

This works fine in the actual app as well as in the compose preview in "Android Studio Dolphin | 2021.3.1 Patch 1" using AGP 7.3.1. But it stops working when using "Android Studio Electric Eel | 2022.1.1 RC 1". I get the following error for the preview:

This is also a problem when using paparazzi to generate snapshot images. The newer paparazzi 1.2 (snapshot version, 1.2.0-20221214.164218-18 to be exact) seems to bring AGP 7.4.0-rc01 with it and with AGP maybe a new layoutlib version?. As soon as I use the new paparazzi version, it overrides my locally defined AGP version and the snapshot-generation fails with the same error I get for the preview in Android Studio.

Other tags like <i> or <u> are still working fine. Maybe it's related to Html.handleEndTag() which adds a fontWeightAdjustment to the SpanStyle for <b>- and <strong>-Tags but that's as far as I got investigating.

I don't think the average developer understands the distinction between method references and method definitions in this context (inside a DEX file). I know I don't.

@jvg, can you elaborate?

Reassigned to jg...@google.com.

people who are looking at the bytecode in the dex to optimize their app through shrinking hopefully will learn the difference as string tables for method references between various dex files can account for quite a bit of disk space. but more importantly a definition is something you can analyze its code for where a reference you can't so the UI can be confusing without seeing the difference

Marked as fixed.

How about something like this?

I think having defined members be directly under the class node while references are nested in a group makes more sense.

Also note that the method refs have a slightly different icon. There is no existing equivalent for field refs that I could find.
