(Godot 3.1) app release version crashes when opening, debug version works fine

I'm about to release my first godot game (in Godot 3.1 stable) in the Google play store and after some succesful closed alpha testing, the app suddenly stopped working in release mode. ('App keeps stopping;) when launching.

I haven't made changes to the game, even backup projects (that used to work fine in release mode) and other simple test projects are now crashing in release mode. Again, all work fine on my device (Pixel 2xl) when in debug mode. It seems like I just overlook something here.

When exporting I just do the usual by selecting the release keystore and pw in the export settings and sign + align the apk afterwards.

Also tried updating the export templates for 3.1 but no result.
Any ideas or potential solutions are more then welcome.

Thanks!

Did you try uninstalling the app first? (Before installing the release version)

You can request some debug dump file in android. (From the debug settings in android)
This is basically a big zipped concatenated log file. Maybe you find some hints about the problem in there. (No root required, just enabled debug settings in android.)

Thanks for the reply,

Yes I did uninstall the previous version of the app first before installing the release version.

The apk is called 'rocketspacer' and several crashes are reported in the log. But I'm not sure where to look at for any solutions for this. I'll keep investigating but any help is appreciated :)

For your convenience, here's the part I think where the crash occurs:

Hi Rikkantio,

It might be a good idea to remove the downloadlink for this logfile again because they sometimes contain personal information.

Your project: Is the renderer GLES3 or GLES2? (Just asking)

I see this line in the log:
org.godotengine.godot.GodotLib.audio [DEDUPED]+94

This may mean nothing. But I'd try to test your release project without sound (at least in the startup scene).

Basically I'd go step by step. So at first I'd set up a new and simple GLES2 demo project. Maybe start with a 2D GUI button. And sign it with your release key.

Then try to incorporate parts of your initial project scene step by step until it fails (or not).

About Android settings:
Do you include "Arm 64 v8a" ? If so, did you try to build with "Arm..7a" only?

I just read about log output here: (probably not your issue)
https://github.com/godotengine/godot/issues/26924

Perhaps enabling "verbose stdout" also works in the release version. They use "adb logcat" to get logs.

Thanks for the reply, appreciate it :).

I agree on the logfile, I deleted it.
My project is a fairly simple 2d game with gles2.
I do connect with internet to submit and receive highscores.
But I tested this already and with both release and debug
It worked perfectly.

Yeah I think that's a good way to go, I'll try exporting the
Game without sound first, just to test that. And then
Like you suggested, troubleshoot it with a simple demo project.

My build is arm7a only.
I'll keep you posted on any updates in the next days.

Thanks a lot for taking the time to look in to it :)

So I did manage to find the problem here.

I've implemented the admob module and I'm using admob export templates from a YouTube video: https://youtu.be/0JdOXZKOwI0
It seems like it has to do with the release export template.
When exporting with the debug template, it makes a proper size apk and runs perfectly on Android.
However when exporting the release apk, the size has shrunk down to less then half size.

I guess I have to recompile the admob export templates myself since for Godot3.1 they are nowhere to be found.

Ok! Glad that you found it!
