How to resize view when touchscreen keyboard is visible on Android with Unity?

Question

In Unity I can't control the touchscreen keyboard. TouchScreenKeyboard class has only one parameters for Android.

if(TouchScreenKeyboard.visible)
{ float keyboardHeight = TouchScreenKeyboard.area.height;
  // will resize the view here! But this return zero!
}

Is there any other way to know the height of the keyboard on Android ?

This should do the trick (found here):

    public int GetKeyboardSize()
    {
        using(AndroidJavaClass UnityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
        {
            AndroidJavaObject View = UnityClass.GetStatic<AndroidJavaObject>("currentActivity").Get<AndroidJavaObject>("mUnityPlayer").Call<AndroidJavaObject>("getView");

            using(AndroidJavaObject Rct = new AndroidJavaObject("android.graphics.Rect"))
            {
                View.Call("getWindowVisibleDisplayFrame", Rct);

                return Screen.height - Rct.Call<int>("height");
            }
        }
    }
