## GetApplicationIdentifier(BuildTargetGroup)

Gets the application identifier for a platform.

> **Warning:**
>
> **Deprecated.** Use GetApplicationIdentifier(NamedBuildTarget buildTarget) instead

```csharp
public static string GetApplicationIdentifier(BuildTargetGroup targetGroup)
```

### Parameters

**** (\[BuildTargetGroup]\(/engine/6000.6/script-reference/unityeditor/buildtargetgroup)): The build target group used to specify the platform configuration targeted, allowing the application identifier to be retrieved for platforms like iOS, Android, or other defined build targets.

### Returns

| Type                                                           | Description                                                                                                                               |
| -------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- |
| [string](https://learn.microsoft.com/dotnet/api/system.string) | Returns the application identifier associated with a [BuildTargetGroup](/engine/6000.6/script-reference/unityeditor/buildtargetgroup.md). |

### Remarks

An application identifier is a unique string that distinguishes an app from others on a given platform. This identifier ensures correct app installation, updates, and access to platform-specific services, making it essential for the app's identity and operation within app stores and devices.

The location that the application identifier is stored in depends on the platform build target. For iOS, tvOS, and macOS platforms, the identifier is written to the `CFBundleIdentifier` field within the /info.plist/ file, which is generated and included in the build output folder when the Unity project is built. Specifically for macOS, the bundle identifier also appears in the /info.plist/ file within the final .app file after the Xcode build process is completed. On Android, the identifier is saved in the `package` field of the /AndroidManifest.xml/ file.

## GetApplicationIdentifier(NamedBuildTarget)

Get the application identifier for the specified platform.

```csharp
public static string GetApplicationIdentifier(NamedBuildTarget buildTarget)
```

### Parameters

**** (\[NamedBuildTarget]\(/engine/6000.6/script-reference/unityeditor/build/namedbuildtarget)): The named build target that specifies the platform configuration targeted, allowing the application identifier to be retrieved for platforms like iOS, Android, or other defined build targets.

### Returns

| Type                                                           | Description                                                                                                                                     |

| [string](https://learn.microsoft.com/dotnet/api/system.string) | Returns the application identifier associated with a [NamedBuildTarget](/engine/6000.6/script-reference/unityeditor/build/namedbuildtarget.md). |
