# @nitra/geolocation

The Geolocation API provides simple methods for getting and tracking the current position of the device using GPS, along with altitude, heading, and speed information if available.

## Install

```bash
npm install @nitra/geolocation
npx cap sync
```

## iOS

Apple requires privacy descriptions to be specified in `Info.plist` for location information:

- `NSLocationAlwaysAndWhenInUseUsageDescription` (`Privacy - Location Always and When In Use Usage Description`)
- `NSLocationWhenInUseUsageDescription` (`Privacy - Location When In Use Usage Description`)

Read about [Configuring `Info.plist`](https://capacitorjs.com/docs/ios/configuration#configuring-infoplist) in the [iOS Guide](https://capacitorjs.com/docs/ios) for more information on setting iOS permissions in Xcode

## Android

This plugin requires the following permissions be added to your `AndroidManifest.xml`:

```xml
<!-- Geolocation Plugin -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-feature android:name="android.hardware.location.gps" />
```

The first two permissions ask for location data, both fine and coarse, and the last line is optional but necessary if your app _requires_ GPS to function. You may leave it out, though keep in mind that this may mean your app is installed on devices lacking GPS hardware.

Read about [Setting Permissions](https://capacitorjs.com/docs/android/configuration#setting-permissions) in the [Android Guide](https://capacitorjs.com/docs/android) for more information on setting Android permissions.

| **`coarseLocation`** | <code><a href="#permissionstate">PermissionState</a></code> | Permission state for coarseLocation alias. On Android it requests/checks ACCESS_COARSE_LOCATION. On Android 12+, users can choose between Approximate location (ACCESS_COARSE_LOCATION) or Precise location (ACCESS_FINE_LOCATION), so this alias can be used if the app doesn't need high accuracy. On iOS and web it will have the same value as location alias. | 1.2.0 |
