Text not displaying on some devices

Solar2D General Questions/Discussion
#1

Hi there,

Weird one this. I have tested my app on 8 different devices (Android and iOS) and it works perfectly. I’ve had no customer complaints about this issue except one person, who owns two of the same kind of tablet (a Versus Android tablet of some kind).

She’s sent me screen grabs from both devices which show that no text is being displayed at all. That includes any text that is part of a button. The text I’m trying to display is meant to be rendered in different fonts depending on where it is (buttons are one font, standard text is another) but neither is displaying.

Has anyone else experienced this?

I really don’t know what I can do. She doesn’t seem to be getting any errors - you can navigate the app fine, it’s just that there’s no text anywhere.

Thanks,

Ian

P.S - I’m using graphics 2.0.

Hi @keystagefun,

May I ask, does the app use extensive masking or nested masks, including tableViews or scrollViews? Does it use any fonts which may, for some bizarre reason, be incompatible with just that one tablet make/model?

Hi Brent,

Thanks for getting back to me.

No tableViews but we do have a few scrollViews. No nested scrollViews or anything though, and the text is missing on all screens, even ones that don’t feature scrollViews.

I use two fonts, both of which are included in the package correctly and both of which work on every other device I’ve ever tested on. No other customer has ever complained about this in two years of using Corona but we did only just upload the new version with graphics 2.0 a couple of weeks ago so if that is part of the issue then this may be affecting more people and we just don’t know it yet.

It’s weird - everything else is displaying fine and the app isn’t crashing - just not displaying the text.

Thanks,

Ian

It could be some type of hardware incompatibility for that device / OS version combo (with corona SDK thrown in)…

For past compatibility issues, sometimes changing android settings (use hardware acceleration, etc), would help to isolate the issue. However, the types of hardware settings available are dependent on the OS version/hardware combo (which there are thousands of course).

So some questions might be:

What android version is it?

Are there Settings that can be tweaked that show changes in text or other (possibly) related graphics? (Such as black rectangles appearing over the text, which becomes visible when changing settings)?

Anyways, just a thought…

Thanks for the reply. I’ll look into these points.

One thing worth noting is another of our apps (which is very similar but is still using graphics 1.0) works absolutely fine on these devices. It also uses the same fonts so those definitely aren’t the issue.

I have this same issue.  I have two text displays.  One always works fine and the other one only works on some devices.  Not sure how to debug this one.  

The one text display always works.  It’s very short.  

The other one fails on some devices. It has a lot of text.  I’ve actually seen this one work on all devices and then later stop working.

I reduced the length of the string and now it’s working.
