On the Android platform, this issue occurs not only in Chaquopy but also in using C API calls.

CPython versions tested on:

3.13

Operating systems tested on:

Android

[mhsmith]

I can't reproduce this with the Chaquopy 16.1.0 demo app:

Python 3.13.0 (main, May  7 2025, 15:54:55) [Clang 18.0.2 (https://android.googlesource.com/toolchain/llvm-project d8003a456 on android
The current application context is available in the variable 'context'.
>>> import platform
>>> platform.platform()
'Android-15-aarch64-64bit-ELF'

Please post the following information:

• The stack trace mentions libpython3.14, but Chaquopy doesn't support Python 3.14 yet. Where did you get the Python build, and how did you integrate it into your app? If possible, link to a GitHub repository containing the app's source code.
• Which device are you testing on, including its Android version?
• Are there any Python versions or devices where the problem does NOT occur?

[ririv]

I successfully retrieved this information Android-15-aarch64-64bit-ELF with C-API and Chaquopy, and the two programs did not crash. However, their Logcat in Android Studio displayed the error log above.

C API with Python 3.14(python.org)

The log above is from running the Android embedded package 3.14 downloaded from python.org using the C API.

I've done some preliminary testing: with Python >= 3.10, the error log appears consistently, while it works fine in 3.8 and 3.9.

Device testing on: macos 26.0 Android simulator
Android ABI: arm64-v8a
Android SDK: 36

[ririv]

And this is Chaquopy repo: https://github.com/ririv/Chaquopy-Android-Test

[mhsmith]

The second log is not actually an error; I think Android just logs a stack trace when changing the signal status for some reason.

The first one certainly looks like a crash to me, so I'm not sure why you're saying it didn't crash. But it appears to be connected to your custom memory allocator, so I suggest you try removing that before blaming Python itself.

[ririv]

Sorry, the first program did crash. I forgot to delete the APK and rerun the new code, causing my emulator to still run the old code.

It used platform.system() to retrieve system information, and in this scenario, the program did not crash.
I modified the code and deleted the emulator's APK before attempting to rerun it using platform.platform(). This did indeed cause a crash.

Regarding the error log in chaquopy, even if it's not actually an error as you mentioned, I can't understand why the error log doesn't appear in Python 3.8 and 3.9. This log confuses me greatly.

I initially thought it was an issue with third-party libraries running on Android, because I discovered this problem when using OpenAI module, which calls platform.platform() to check if the system is Android.

[ririv]

Regarding the custom memory allocator, I'll delete it immediately and try again.

[ririv]

I made two attempts. First, I removed the custom memory allocator.

I found that when calling platform.system(), the program ran normally without crashing and successfully obtained Android in the emulator.
However, after calling platform.platform(), the program logged an error stating it couldn't find the _struct module.

Of course, this is an issue with my C code, so I modified the python_bridge.c file by adding the following code to fix the detection of the C extension module:

    char python_lib_dynload[256];
    strcpy(python_lib_dynload, python_home);
    strcat(python_lib_dynload, “/lib-dynload”);
    wchar_t *python_lib_dynload_w = Py_DecodeLocale(python_lib_dynload, NULL);
    if (python_lib_dynload_w == NULL) {
        LOGD(“initPython: Py_DecodeLocale for lib-dynload failed”);
        goto exception;
    }
    status = PyWideStringList_Append(&config.module_search_paths, python_lib_dynload_w);
    if (PyStatus_Exception(status)) {
        LOGD(“initPython: PyWideStringList_Append for lib-dynload failed”);
        goto exception;
    }

Now, the program reproduces the previous error.

The program did not crash, and Android-16-aarch64-64bit was successfully obtained and displayed in the emulator, but the error log persists.

This the lasted log:

And this the lasted code for the first program, you can know what I modified through the commit.

As you said,

The second log is not actually an error; I think Android just logs a stack trace when changing the signal status for some reason.

I think that this log information is not an error, it just appears as an Error to notify developers.

[ririv]

I've closed the issue for now. We can continue discussing this, and you can also verify whether this error log is actually an error. After all, such error information is confusing.

Additionally, what I don't understand is why calling platform.platform() on Chaquopy with Python 3.8 and Python 3.9 doesn't produce this kind of information.

[mhsmith]

even if it's not actually an error as you mentioned, I can't understand why the error log doesn't appear in Python 3.8 and 3.9. This log confuses me greatly.

Yes, I was confused as well the first time I saw it, but I think it's harmless. If it doesn't appear on different versions of Python, it's probably because they interact with signals in a different way.
