Crash in android with dev build

[J-L MG]

Hello I tried making an android build for a very simple game but it crashes, here is what I can find in debug log:

I'm using:

- flixel-dev 

- lime 2.6.8

- openfl 3.3.8

Command used is default flashdevelop : "haxelib run lime run "Project.xml" android -debug"

Is this a mistake from my code? Since we have "Null Object Reference" but I don't know where to look..

Thanks in advance for your help

Edit: Doesn't crash with flash.

* It's your code.
* Where? probably in your tweens. Something isn't initialized to begin with or being destroyed prematurely.
* Since it's a simple game, you can always try commenting out some blocks.
* You can try HxScout.
* You can try building your game with the standalone debug Flash player for more info.

The flash debug version didn't have any crash, that's my problem. But after checking the tweens I didn't destroy one properly which I think made the game crash on android I'm not 100% sure since the crash were inconsistent but we'll see, thanks for the quick answer!

Also if there is any way to have better debugging for android I'd be happy to learn about it because for large projects it must be quite painful!

HxScout: http://hxscout.com/

SruloArt thanks for that link it seems very useful and would avoid a lot of stupid questions from me but I have troubles getting it to work:

using the test haxeflixel project from the repo: https://github.com/jcward/hxtelemetry/tree/master/test/HelloFlixel

I get this error "source/Main.hx:24: characters 4-10 : Unknown identifier : openfl"

for this line: "openfl.Telemetry.config.app_name = "HaxeFlixel";"

I read from the userguide that openfl versions 3.1.1 or newer have telemetry and I'm using the 3.3.8 version of openfl, I also updated hxcpp and followed that userguide so I'm really confused.

What am I doing wrong? Command used is "run lime build "Project.xml" windows -debug -Dfdb -Dtelemetry"

Thanks a lot for the help! (should I make a new question regarding hxscout so it's easier for other people to find the answers?)

Hi -

Sorry, the HelloFlixel example was out of date. I fixed it. It looks like you have the proper libarries installed - all you should need to do to profile any HaxeFlixel project is add -Dtelemetry to your openfl command, which it looks like you've done that as well.

Let me know if this doesn't work.

However, I might add that hxScout may not help you debug a crash... It's a profiler, more for debugging lag, where code spends the most time, etc.

Best,

-Jeff

I confirm the issue is fixed for me both on test project and my own project, thanks a lot Jeff Ward you made a very good tool I am new to open-source but I hope to become a good developer like you to contribute like this, big thanks. Sorry for my stupid questions and bothering.

Thank you, glad you got it working!
