# Fonts

> Configure system and custom fonts in the Userpilot Android SDK

Configure system and custom fonts used in Userpilot experiences, including resolution order, weights, and multi-module support.

The Userpilot Android SDK supports system and custom fonts for rendering experiences, ensuring visual consistency across your app with dynamic fonts, weight mapping, and text scaling.

## Overview

When building an experience, you can specify the font family name. The SDK will search and apply the font automatically so the selected font renders consistently across your app.

## Font Sources and Resolution Order

The SDK resolves fonts by checking the following sources in order:

1. **System Fonts**: Standard Android typefaces such as `default`, `serif`, and `monospaced`.
2. **Resources**: Fonts defined in the `res/font` folder of the SDK or client apps.
3. **Assets**: Fonts stored in the `assets/fonts/` directory.
4. **System Font Directory**: Custom fonts located in `/system/fonts`.

## Font Weight Handling

The SDK converts weight strings (for example, `bold`, `light`) to a `Typeface` style or integer value using the `FontWeight` enum.

## Multi-Module Apps or Custom App IDs

If your app supports multiple modules and you want to use a font from one of them, provide the module's package name so the SDK can locate the font.

```kotlin theme={null}
userpilot = Userpilot(context, "<APP_TOKEN>") {
    packageNames = listOf("com.example.features")
}
```

## Error Logging

If a requested font cannot be found, an error message is logged to help debug issues during SDK development or integration:

```plaintext theme={null}
Font "fontName" not found!
```
