The call from my app

LocalNotification.SendNotification(1, miliSeconds, StaticStrings.notificationTitle, StaticStrings.notificationMessage,"soundName", new Color32(0xff, 0x44, 0x44, 255), true, true, true, "app_icon");

and the call from the LocalNotification class

public static int SendNotification(int id, long delayMs, string title, string message,String soundName, Color32 bgColor, bool sound = true, bool vibrate = true, bool lights = true, string bigIcon = "")
    {
		
#if UNITY_ANDROID //&& !UNITY_EDITOR
        AndroidJavaClass pluginClass = new AndroidJavaClass(fullClassName);
        if (pluginClass != null)
        {
		Debug.Log(" pluginclass not nulll");
            pluginClass.CallStatic("SetNotification", id, delayMs, title, message, message, 
		sound ? 1 : 0,soundName, vibrate ? 1 : 0, lights ? 1 : 0, bigIcon, "notify_icon_small", 
        bgColor.r * 65536 + bgColor.g * 256 + bgColor.b, "bundle", "channel", Application.identifier);
        }
		Debug.Log(" pluginclass  nulll : id : " + id);
        return id;

How do i fix this and what wrong am i doing ?

if use progaurd in your project add this line to your progaurd-user.txt file to prevent exeption:

#----------------dont obfuse class name (local notification plugin) : because call them with name in C# unity
-keep class net.agasper.unitynotification.** { *; }
