Game won't run on any tablet devices [Solved]

Hello.

I've made a game using C3 and published it for Android.

It's now available on the Play Store and works on every phone.

The problem is this: it doesn't run on any tablet. The loading bar runs, and then the app just closes. No message.

I know there could be many reasons for that, but what could possible be the cause for preventing it to specifically run on ANY tablet, while running on every phone? How can I pinpoint the cause?

I'm totally lost...

I searched the forum, but I couldn't find another case like this.

Thanks in advance for any help.

does it run on a tablet if you do a remote preview? or an HTML export?

are you using any plugins that require a feature only found on phones?

No, it has the exact same behaviour as when I run the installed app...

I don´t think so. I'm using just the most basic and standard plugins (audio, sprite, touch,...).

Any clue what it could be? :(

Thank you for your time.

Additional information:

In an attempt to find the problem, I created a backup of my project and have been experimenting with it.

This is what I tested:

-Deleted all the event sheets from the project - still didn't run on tablet

-Deleted all layouts from the project (except starting layout) - still didn't run on tablet

-Deleted all images/object types from the project (except the image at the starting layout) - RAN ON TABLET

What does this mean??

Are the images the problem?

Is there one image in there that's breaking the game?

Are there too many images (there are 415) ?

You might be running out of memory if it'S an old tablet

I see... You're probably right...

The weird thing is that, so far, no tablet (that I know of) has been able to run it.

Anyway, could the huge ammount of images in the project be the cause of the excess memory usage? (I was hoping the "deduplicate" feature would save me from that problem, since there are many cloned objects in the project. Looks like I was wrong)

400 doesn't sound unreasonable. Do you have some large sprite(s)? Maybe something over a couple thousand pixels wide and tall?

Hey,

here some tips: In the "Project bar" go right click on the project name, then "tools" -> "view project statistics". There check this sentence: "Estimated peak memory usage is..." For mobile games you should try to keep it around 150 MB or less. I don't recommend to go above that because then you will have especially older / cheaper phones / tablets which can't handle the memory usage.

If that's not the point in your case, here is another problem with images I had: Please check if you have any tiled-backgrounds which are very small (1x1px) and scaled up to fit the whole background or anything like that. This will let the game crash on specific phones / tablets (this has nothing to do with how good the phones are, but this error appeared only on some phones and there every time...).

Also check if you have any tiled-backgrounds which are completly transparent (so no image is shown, it's just a transparent file). This will also cause these crashes.

Wow, that's a lot of helpful tips there!

Thanks, Kyatric and CGamez. I'll be sure to check all that today!

Don't think so. I get a warning message whenever I try to export a project containing a large sprite, so I don't think that's the case. But I'll be sure to check it manually, just in case.

Thank you guys for your help. Now I have plenty of clues to follow! Till now, I've been trying alone for weeks, with no idea where to start.

Hopefully I'll get around this issue! I'll let you know when I do :)

I just did that. It's 594 mb!! Daaaaamn!!

Well, I guess at least I found the problem.

Now, time to restructure the whole game, I guess -_- AHAH!

Although, modern devices should be able to handle 1G worth of vram use. But 600 is still quite a bit unless your project is massive, so I'm sure there are ways you can optimize memory use.

Yes, I have been resizing images for the past hours. Hope it works.

700 to 140? Wow! What do you mean by "spliting" images?
