Works in android emulation and gideros player, not on device (2.3)

rc3

Finishing game and the menus work fine, but the minute we choose "New Game" the screen goes white and it's gone with no returning. I can exit to home and then go back into app, but can't actually get to the new game screen. Help. iOS version is ready and submitted to Apple, but need to clear up Android issues. Thanks so much.

Hi,

white screen means there is a Lua error. Which version are you using? If your version is older than beta8, can you upgrade to beta8 and try again?

88.198.22.6/downloads/beta

MikeHart

Maybe a sound format issue. That is all I could say without seeing your code.

rc3

2011.9 beta 8 - I checked that first. Thanks for the quick response. Paolo said you guys were good at that

atilim

btw, I'm really curios about the details of your game. :-?

rc3

Maybe a sound format issue. That is all I could say without seeing your code.

All .wav, so that should be ok.

MikeHart

Are you writing into files? If yes, how (code please) ?

atilim

Also on Android, Lua errors can be viewed from LogCat. If you can catch the error (plug your phone, open eclipse and open LogCat view) that will be very informative.

rc3

I export the project, then import into Eclipse. I've mostly been on the iOS side, but I do have some apps in the Android Market as well. It's been a while since I've used Eclipse, so part of it might just be a "relearning" curve.

atilim

Than you can easily find the LogCat view.

rc3

After importing, the initial error is : Android requires compiler compliance level 5.0 or 6.0. Found '1.4' instead. Please use Android Tools > Fix Project Properties.

Which I did.

atilim

Ok. The better way is right click project name, select Properties > Java Compiler > Enable project specific settings > JDK Compliance > 1.6

Then run your project.

rc3

Same result and I'm not seeing any errors in LogCat

Maybe a stupid question, but if it's a Lua error, shouldn't it appear in Gideros Studio?

atilim

If run within player yes, if exported as an application no

rc3

It works well from player.

rc3

Thanks to Atilim, we altered two small lines of code and "viola".... it works. What a wonderful developer community with a great product.

Thanks again to all.

ar2rsawseen

was it a common mistake? maybe you could share error with others, if it's not private of course.

rc3

We used a "require" command and because all Lua files are executed automatically it was not... for any better word... required.
(Any require calls should be deleted)

atilim

You're right The mistake was using of require command. We removed it and made a local table global then problem solved.

Hi atilim, do you know a game template on this forum: http://giderosmobile.com/forum/discussion/480/gideros-game-template ? I found that template use "require" command, and play "mp3" file, but it's built ok on Android (eclipse). So I think "require" command maybe not the main problem.
I've been stuck in building my app on Android and try to find the reason. Will we have other reasons about this?

Thank you.

I have the same problem.
My project works on Gideros Player Android, on Gideros player windows. I imported the project to eclipse and generate my own apk file. On real android device this apk file only runs the Gideros Splash screen, after that, a white screen is showed for 1 second and finally the execution program finish.

I remove the "require" command but still the problem persist. I use the tntCollision library, maybe there is a problem with this library.

Any help how I can compile my program?

ar2rsawseen

@tuanleanh I think require command in template is only used for box2d, because it can't be loaded other way.
Using require for lua files may consume twice as much memory, because scripts are loaded two times, which may also break your code.


Thus require may be used for external libraries, not for files included in the project.
For android your best bet is to launch app in debug mode in eclipse and look for errors in LogCat?

Most common Android mistake is the case sensitivity of files. Make sure your file names and extensions are in same case that you use in the code.

@MysiaGames tntCollision is an external library, that probably should also be included in eclipse project.

MysiaGames

Yes, I included the tntCollision files on Eclipse. I got the next log after Gideros splashscreen:

---------------------------------------------

Update: forgot my problem. Now it's working fine. I rename my lua project all in lowercase and problem finished.
