HeliBoard 4.0-alpha2

[Helium314]

Changes since 4.0-alpha1:

• fixes to background gesture data gathering
• fix crashes related to clipboard history
• spellechecker: don't report mostly-non-letter words as typo
• minor improvements

---

This discussion was created from the release HeliBoard 4.0-alpha2.

When I click on the link to alpha2

[Helium314]

For whatever reason Github decided to keep it a draft...

[Mjohansson77]

Did you see what I wrote about the icon?
In the 4.0-alpha1 the clipboard icon not colormatch #2554

[Azzipp]

Minor, but custom font doesn't apply to the autofill pills even though it applies everywhere else on the keyboard.

[Azzipp]

I switched from 3.9, which didn't have custom font applying anywhere except main keyboard keys, but I think it should apply to inline autofill pill because it's applied to clipboard pill:

[maruuk]

Does it apply to clipboard suggestions for you in 4.0? Mine stopped after updating.

[Azzipp]

Yeah, 4.0-alpha2

[Helium314]

Inline Autofill might be different because HeliBoard just forwards the data.
A style is provided, but TextViewStyle doesn't support a custom typeface.

Clipboard suggestionn also showing custom font for me

[maruuk]

Oh, it's not a problem with the custom font. It's applied correctly; I've checked several. Something's wrong with the default one. The clipboard suggestion has a different font now.

3.9

4.0

[Azzipp]

I get this crash after saving passive gestures by clicking the button once.

[Helium314]

Not sure how this can happen, but at least should not crash any more

[Azzipp]

Cleared data and restored backup, works fine now without crashing.

I did however notice that after disabling incognito mode to enable passive gathering, the circle shifted my keyboard up. Have noticed it on other occasions maybe four times, but it's not permanent and drops down correctly after I type or gesture something else, I think.

spellechecker: don't report mostly-non-letter words as typo

Thanks for this. It seems that emojis and single letters are no longer treated as typos, but numbers, symbols and links are still underlined. Can this also be improved?

[Helium314]

It surely can, but with spell checker things I'm mostly waiting for contributors because for whatever reason both my test phones stop the spell checker for a long time when I launch a debug build, and that's absolutely horrible for development.

[maruuk]

I'd be happy to test it if you could send me the APK files. Changing the spellchecker seems to work quickly on my phone.
