Question

I am unable to run my game in android without including my source code in the assets folder. The documentation says I should use --main-pack <pck_or_zip_filepath_relative_to_assets_dir> but after exporting my game to the assets folder as game.pck and setting the commandline to --main-pack game.pck I get the following error:

1: USER ERROR: Cannot open resource pack ‘game.pck’.
2: at: _setup (core/config/project_settings.cpp:534)
3: Error: Couldn’t load project data at path “.”. Is the .pck file missing?
4: If you’ve renamed the executable, the associated .pck file should also be renamed to match the executable’s name (without the extension).
5: Unable to setup the Godot engine! Aborting…

At this point I thought maybe the .zip will work but when doing that I get the following error:

1: USER ERROR: Condition “f.is_null()” is true. Returning: nullptr
2: at: godot_open (core/io/file_access_zip.cpp:51)
3: USER ERROR: Parameter “zfile” is null.
4: at: try_open_pack (core/io/file_access_zip.cpp:171)
5: USER ERROR: Cannot open resource pack ‘project.zip’.
6: at: _setup (core/config/project_settings.cpp:534)
7: Error: Couldn’t load project data at path “.”. Is the .pck file missing?
8: If you’ve renamed the executable, the associated .pck file should also be renamed to match the executable’s name (without the extension).
9: Unable to setup the Godot engine! Aborting…

Including all my game files in the assets dir without using --main-pack works but I would prefer not contain all my game code there.

Hey! I hope this is still relevant :slight_smile:
I’ve been able to work around this by doing the following:

  1. Export your game as a .zip as you’re doing now
  2. Extrack this zip into the assets folder of your android project (src/main/assets by default)
  3. Remove --main-pack argument from command line

I follow you steps but found the same error :sob:
this is my code below,

@Override
    public List<String> getCommandLine() {
        return List.of("game.zip");
    }

and I put the game.zip in the src/main/assets.
So is some steps I did were not correct?
Thanks in advance

Hm, I don’t think you need to override getCommandLine function all together. Have you tried without it?

I export my godot project in windows platform and excute
“Godot_Demo.console.exe Godot_Demo.pck” , it works .
But in android platform , I don’t know how to embed the .pck or .zip if I do not override the getCommandLine() function. If you don’t mind, could you show me your sample code?
Thank you so much

This Godot Android library — Godot Engine (stable) documentation in English is the approach that I’ve been using. And here is the sample mentioned there: Godot-Android-Samples/apps/gltf_viewer at master · m4gr3d/Godot-Android-Samples · GitHub

My approach is the same and they also don’t override getCommandLine function

The sample app provided by official is that put all godot code and art assets in src/main/assets, but actually I don’t want to expose my godot code.I followed the document and found that it is possible to create the Godot project in a separate directory and export it as a .pck file. Then put the .pck file exported into src/main/assets.

However, after my continuous attampts , I finailly succeeded. :grinning: My code is as follows:
@Override
public List getCommandLine() {
return List.of(“–main-pack”,“res://game.pck”);
}

Indeed
What I’m saying is that if you extract that .pck into the assets folder then you wouldn’t need getCommandLine at all.

Anyway, I’m glad that worked out for you! :slight_smile:

There is a commandline/extra_args option in Android Export Preset. It is more convenient to set main pack option there.

BTW, how do you run the gradle build after repalcing the assets files? I tried to run gradle from command line, but it requires a lot of options. All the options are generated by Godot Android Export.
