# sdkRootPath

> Path to the Android Software Development Kit (SDK) used for building Android applications.

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor.Android](/engine/6000.6/script-reference/unityeditor/android.md)
* **Assembly:** UnityEditor.Android.Extensions

```csharp
public static string sdkRootPath { get; set; }
```

### Remarks

* If you provide an empty string or a null, Unity enables the **Installed with Unity (recommended)** option in the Android section of the **External Tools** window.
* If you provide a valid, non-empty path, Unity disables the **Installed with Unity (recommended)** option and uses the SDK at the specified path.
* If you provide an invalid, non-empty path, Unity throws an exception.

### Examples

```csharp
using UnityEngine;
using UnityEditor;
using UnityEditor.Android;

public class SdkPathManager
{
    [MenuItem("Build/Set Custom SDK Path")]
    public static void SetSdkPath()
    {
        // Set a custom path for the Software Development Kit (SDK)
        string customSdkPath = "/path/to/your/sdk";

        AndroidExternalToolsSettings.sdkRootPath = customSdkPath;
        Debug.Log($"SDK Path set to: {AndroidExternalToolsSettings.sdkRootPath}");
    }

    [MenuItem("Build/Reset SDK Path To Default")]
    public static void ResetSdkPath()
    {
        // Reset SDK path to Unity's default
        AndroidExternalToolsSettings.sdkRootPath = string.Empty;
        Debug.Log("SDK Path reset to 'Installed with Unity (recommended)' path.");
    }

    [MenuItem("Build/Get Current SDK Path")]
    public static void GetSdkPath()
    {
        // Retrieve the currently configured SDK path
        string currentSdkPath = AndroidExternalToolsSettings.sdkRootPath;

        Debug.Log($"Current SDK Path: {currentSdkPath}");

    }
}
```
