# Beeware crash loading `pydantic_core` on Android
The purpose of this repo is to provide a reproducible sample project for a bug in an Android app created using [Beeware briefcase](https://github.com/beeware/briefcase).
## Summary
The application, it if worked, would fetch data from a graphql endpoint and display it on the screen. It uses the [pydantic](https://pypi.org/project/pydantic/) library when doing graphql queries.
The `briefcase build android` command doesn't seem to package the [pydantic_core](https://pypi.org/project/pydantic-core/) library inside the app, which causes app crashes at runtime, on app startup.
## Environment
* Build machine: MacOS Sonoma 14.1, Intel chip.
* Python 3.11.6
* Android devices tested:
- Genymotion Cloud emulator, Android 11, x86_64.
- Google Android emulator: Pixel 3, Android 11, x86_64.
- Samsung Galaxy S10+, Android 13.
## Steps to reproduce the issue
* Install requirements: `pip install -r requirements.txt`
* Go into the `helloworld` subdirectory: `cd helloworld`
* Run the app on your local computer: `briefcase dev`
* Click on the "Fetch!" button
- Verify that the screen displays "A New Hope was released in 1977-05-25"
* Run the app on an Android device/emulator:
- `briefcase create android`
- `briefcase build android`
- Start and Android emulator, or connect an Android device to your computer.
- `adb install -r build/helloworld/android/gradle/app/build/outputs/apk/debug/app-debug.apk`
- Start to capture android logs: `adb lolcat -v threadtime > /tmp/logcat.txt 2>&1 &`
- Launch the app.
- Expected behavior: the app ui appears:
- Actual behavior: the app crashes. The following appears in `/tmp/logcat.txt`:

## Analysis
The `briefcase build android` command shows that the `whl` file for `pyndantic_core` which is being pulled in is the macosx build:
```

```
I guess the correct behavior would be to download or build the whl appropriate for the Android platform.
