How to open the Android settings through Unity?

I need to open the notifications setting on Android for my app. Does anyone know how to do this? Thanks

 

You need to write a tiny iOS plugin for that, here is more information about it: http://docs.unity3d.com/Manual/PluginsForIOS.html

And here is your solution, ask if something should be unclear.

Script/Example.cs

using UnityEngine;

public class Example
{
public void OpenSettings()
{
#if UNITY_IPHONE
string url = MyNativeBindings.GetSettingsURL();
Debug.Log("the settings url is:" + url);
Application.OpenURL(url);
#endif
}
}
Plugins/MyNativeBindings.cs

public class MyNativeBindings
{
#if UNITY_IPHONE
[DllImport ("__Internal")]
public static extern string GetSettingsURL();

[DllImport ("__Internal")]
public static extern void OpenSettings();
#endif
}
Plugins/iOS/MyNativeBindings.mm

extern "C" {
// Helper method to create C string copy
char* MakeStringCopy (NSString* nsstring)
{
if (nsstring == NULL) {
return NULL;
}
// convert from NSString to char with utf8 encoding
const char* string = [nsstring cStringUsingEncoding:NSUTF8StringEncoding];
if (string == NULL) {
return NULL;
}

// create char copy with malloc and strcpy
char* res = (char*)malloc(strlen(string) + 1);
strcpy(res, string);
return res;
}

const char* GetSettingsURL () {
NSURL * url = [NSURL URLWithString: UIApplicationOpenSettingsURLString];
return MakeStringCopy(url.absoluteString);
}

void OpenSettings () {
NSURL * url = [NSURL URLWithString: UIApplicationOpenSettingsURLString];
[[UIApplication sharedApplication] openURL: url];
}
}
