NullPointerException in my game

albert988

My game has a bug which is nullpointer exception

the line is "GiderosApplication.getInstance().onDrawFrame();"

Is it that the GiderosApplication.getInstance() is null ? Why would that happened?

Hello @albert988,
is there anything more in error message, can you copy paste the full stack trace/log you have?
Any other info you have, error repeat scenario, video, etc

Most probably there is an error in Lua or somewhere before leading to the error on DrawFrame

@ar2rsawseen

that's all I got in flurry

may be it's in Lua but I don't implement flurry in Lua

ar2rsawseen

You mean report is in Flurry right?
But your app is Gideros, thus it has lua code also, doesn't it?

@ar2rsawseen: I have had the same type of report from Flurry. Unfortunately, Flurry only gives the 3 lines of stack trace and no other information. These errors are intermittent and I have never seen them occur myself, only in the Flurry error reports.

As you can see these are not very informative (or for that matter very helpful other than letting you know there is some kind of problem).

ar2rsawseen

Well if the percentage of errors is quite low, I guess thats nothing to worry about, but well yes, with the provided information, there is nothing to determine more or at least have a guess on what went wrong.

albert988

Just exactly like @Scouser said

hope Gideros can add Flurry in Lua code and supported Android

ar2rsawseen

@albert yes it is already done and most probably will be available with the next version. Still I think error is not flurry related, flurry just gets the report.

Scouser

I'm 100% confident as @ar2rsawseen it's not Flurry that's causing the errors. I think that it would be more helpful to have known what version of Android were running when the errors happened.

Maybe we should use something like android-remote-stacktrace. Or as @atilim suggested in January Please integrate Crittercism (or any other alternative)

@ar2rsawseen

I found another error for Gideros, it's a Runtime Error this time, please check it out.

And this one

an audio error

fxone

hello @albert988 I have some problem after first touch at the beginning of game (Lite version 1.0.1). "Lost! Tap to play again!" occurs again and over again. It's looped. The game boy even has not moved.. Tested on Froyo, arvmv-6, alcatel ot-908 (t-mobile move)

@fxone
I knew this bug and fixed it now, thanks

But I think the null pointer error is not relative to this bug.
