How to get property from Settings.System

Hello,

I need to check if the Airplane mode is currently active, so I found this thread:
http://stackoverflow.com/questions/4319212/how-can-one-detect-airplane-mode-on-android

I want to implement it in Unity so I tried the following:

Code (CSharp):

1.  
2.  
3. public void CheckAirPlaneMethodNew()
4.     {
5.         AndroidJavaClass systemGlobal = new AndroidJavaClass("android.provider.Settings.Global");
6.         var airplaneMode = systemGlobal.Get<int>("AIRPLANE_MODE_ON");
7.         Debug.Log("Airplane Mode is Now = " + airplaneMode);
8.     }
9.  
10. public void CheckAirPlaneMethodOld()
11.     {
12.         AndroidJavaClass systemGlobal = new AndroidJavaClass("android.provider.Settings.System");
13.         var airplaneMode = systemGlobal.Get<int>("AIRPLANE_MODE_ON");
14.         Debug.Log("Airplane Mode is Now = " + airplaneMode);
15.     }

The difference between the two is the class name: android.provider.Settings.Global in newer sdk
and android.provider.Settings.System in the older ones

But in both cases I am getting the following error:
AndroidJavaException: java.lang.ClassNotFoundException: android.provider.Settings.Global
and
AndroidJavaException: java.lang.ClassNotFoundException: android.provider.Settings.System

So I don't know if my code is wrong or if these classes are not included when building APK from Unity

Any help is welcomed!

 

Anyone?

 

You should look at the docs here: https://developer.android.com/reference/android/provider/Settings.Global.html#AIRPLANE_MODE_ON

There are a few issues with your code that you should check out:

1. The string value of the property to check for is 'airplane_mode_on'.
2. Also, the Settings.Global class was added only in api level 17.
3. Lastly, Both classes are nested classes (e.g: an inner class inside the Settings class), so the syntax for retrieving them may be different.

You can try with this code (i wrote it in a text editor, not sure that it'll work):

Code (CSharp):

1. public void CheckAirPlaneMethodNew()
2. {
3.     // Get context
4.     using (var actClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
5.     {
6.         var context = actClass.GetStatic<AndroidJavaObject>("currentActivity");
7.         AndroidJavaClass systemGlobal = new AndroidJavaClass("android.provider.Settings$Global");
8.  
9.         var airplaneMode = systemGlobal.CallStatic<int>("getInt", context.Call<AndroidJavaObject>("getContentResolver"), "airplane_mode_on");
10.        
11.         Debug.Log("Airplane Mode is Now = " + airplaneMode);
12.     }
13. }
14.  
15. public void CheckAirPlaneMethodOld()
16. {
17.     // Get context
18.     using (var actClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
19.     {
20.         var context = actClass.GetStatic<AndroidJavaObject>("currentActivity");
21.         AndroidJavaClass systemGlobal = new AndroidJavaClass("android.provider.Settings$System");
22.        
23.         var airplaneMode = systemGlobal.CallStatic<int>("getInt", context.Call<AndroidJavaObject>("getContentResolver"), "airplane_mode_on");
24.        
25.         Debug.Log("Airplane Mode is Now = " + airplaneMode);
26.     }
27. }

Let me know if this helped

 

@liortal Thank you very much, it works like a charm!
