I cant use findviewById in java...
this library is just for kotlin?
help me plaese I am java develooper .
thanks.

I am using the component TextViewJustify class. to this class i am setting the text "A motorist traveling to thiruvananthapuram at 10m/s can bring his car to rest in a distance of 10 m."
I am using android:justificationMode="inter_word"

actual:
"A motorist traveling to thiruvananthapuram at 10m/
s can bring his car to rest in a distance of 10 m."

expectation is:
"A motorist traveling to thiruvananthapuram at 10m/s
can bring his car to rest in a distance of 10 m."

I was wondering if adding support for the various \big, \Big, \bigg, and \Bigg commands is on the roadmap?

mathview = findviewbyid.............
mathview.latex = "x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}"
"latex" showing red ... seems no latex attribute there. how to solv this?

Is it possible to get the bounding box of the actual rendered content, meaning the height and the width from the canvas?

Is there a way to change the font?

I got some rendering issue on some devices. It is not rendering at all on some devices when I install a debug APK. (Image A) When I create a release APK, it renders overlapped. It's unreadable (Image B). But some devices same project working properly. (Image C)

I tried it on more than 10 devices (deferent OS, deferent model) manually and on half of them not working properly. Also I observed that same device (model) has working and not-working issue.

Any help ?

Thanks !
Hashan.

Image A - DEBUG MODE PREVIEW (not rendering) :

Image B - RELEASE MODE PREVIEW (overlapped) :

Image C - WORKING PROPERLY :

(Image A and B on same device (Samsung Galaxy A01) C on Samsung Galaxy A50)

Getting target exception in the XML mentioning library <com.agog.mathdisplay.MTMathView when compileSdkVersion and targetSdkVersion increasing to 30 and 31 may be in jcenter and maven { url "https://jitpack.io" } is deprecated in api level 30 and 31. Dependency is not working increasing api level please take it as a priority and fix the issue.

This library is pretty good for now, just a little bit issue, and I'm happy to do some fixes and adaptation.

I tried to find the cdep library from the original author and google's repo, but it seems like the project cdep is terminated.

Specifically, this jar file can not be found.

Any help?

'\text{Slope of line }\mathrm{AB}=\frac{\Delta{C}}{\Delta{F}}

\\=\frac{100-0}{212-32}=\frac{100}{180}=\frac{5}{9}
'

if we added the extra space after the Delta{F}} its working fine. Please refer the below letax. our expectation should work with above formula.. Please refer below screenshot. which is highlighted because u can understand the whitespace.
  '\text{Slope of line }\mathrm{AB}=\frac{\Delta{C}}{\Delta{F}} 

\\=\frac{100-0}{212-32}=\frac{100}{180}=\frac{5}{9}
'

Trying to use padding on the view make it invisible !
Thanks.

There is an error when trying to render this command (cfrac):

\cfrac{a}{1 + b}

There is no such issue for frac.

When building this library in modern AndroidX environment, there are dependency resolution errors, as such:

There is a way to fix it by enabling jettifier. It would be much better if these issues were fixed at the library level. @gregcockroft, please consider adapting your very helpful library to AndroidX.
