Missing cookie: {cls.anon_cookie_name}

Error message

Missing cookie: {cls.anon_cookie_name}

What it means

buildAndroidRunner expects the C runner source at <binDir>/pyandroid_runner.c before invoking clang. That file is supposed to be written from the androidRunnerC constant embedded in the Go binary; its absence means the write step was skipped, failed, or the file was deleted between setup stages.

Solutions

1. Re-run the full setup so the step that writes pyandroid_runner.c (from the embedded androidRunnerC constant) executes before the build
2. Check binDir is writable: touch <binDir>/test && rm <binDir>/test; fix storage permissions or move binDir to app-internal storage
3. Verify the caller order in the setup flow: source write must precede buildAndroidRunner — add the write call if a refactor dropped it
4. As a workaround, copy the runner source manually into <binDir>/pyandroid_runner.c and retry

Example fix

// before — build invoked directly
if err := buildAndroidRunner(binDir); err != nil { ... }

// after — ensure source is written first
if err := os.WriteFile(filepath.Join(binDir, "pyandroid_runner.c"), []byte(androidRunnerC), 0o644); err != nil {
    return fmt.Errorf("write runner source: %w", err)
}
if err := buildAndroidRunner(binDir); err != nil { ... }

src := filepath.Join(binDir, "pyandroid_runner.c")
if _, err := os.Stat(src); err != nil {
    if err := os.WriteFile(src, []byte(androidRunnerC), 0o644); err != nil {
        return fmt.Errorf("write runner source: %w", err)
    }
}

When it happens

Trigger: Code path invoking buildAndroidRunner without first writing androidRunnerC to disk; a prior os.WriteFile of the source failing (read-only binDir) and the error being ignored; manual cleanup of binDir removing the .c file but leaving python-home.

Common situations: Partial setup state after a failed earlier run; binDir on external storage mounted read-only at the time; a code change calling buildAndroidRunner from a new path that skips the source-write step.
