Preview render presentation in Studio Studio after upgrade

Question

I'm so confused. It worked great before the most recent upgrade to Android Studio 3.0.

All my xml files have the same rendering problem. I can not see anything.

It says:

"Failed to initialize android.graphics.Typeface class

Rendering exception: Failed to initialize android.graphics.Typeface class

Tip. Try updating the layout. "

No matter how many times I try to update this thing, it just won't work. I restarted Android Studio, but it still won't work.

I do not know where to start with this problem, because I had never seen such a problem before. I googled it, but I could not find anything useful.

I need help. Please save me!

C:\Program Files\Android\Android Studio\plugins\android\lib\layoutlib\data\fonts

fonts.xml

<?xml version="1.0" encoding="utf-8"?>
<!--
    WARNING: Parsing of this file by third-party apps is not supported. The
    file, and the font files it refers to, will be renamed and/or moved out
    from their respective location in the next Android release, and/or the
    format or syntax of the file may change significantly. You must not
    parse this file for information about system fonts. Instead, you must
    call android.text.FontManager#getSystemFonts(). For example, it can be
    called as context.getSystemService(FontManager.class).getSystemFonts().
    Note that the returned FontConfig includes data on all the defined font
    families and all the details about weight, style, etc. It also provides
    an open file descriptor to each font file. Note that callers of the API
    should ensure they close the given file descriptors once they are done
    using them.

    In this file, all fonts without names are added to the default list.
    Fonts are chosen based on a match: full BCP-47 language tag including
    script, then just language, and finally order (the first font containing
    the glyph).

    Order of appearance is also the tiebreaker for weight matching. This is
    the reason why the 900 weights of Roboto precede the 700 weights - we
    prefer the former when an 800 weight is requested. Since bold spans
    effectively add 300 to the weight, this ensures that 900 is the bold
    paired with the 500 weight, ensuring adequate contrast.

Answer 4

, fonts.xml .

In my case, I have a font; NotoSansCJKkr-Regular, which is used on my computer in the Windows fonts folder, I modified the fonts.xml file to fit this font. Since the source file fonts.xml does not have a font name. So I needed to add a font.
