AndroidPlugin.cs

using UnityEngine;

public class AndroidPlugin : MonoBehaviour
{

    public void ToastMakeText(string message)
    {

        var javaUnityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");

        var currentActivity = javaUnityPlayer.GetStatic<AndroidJavaObject>("currentActivity");

        var androidPlugin =
            new AndroidJavaObject("com.scottdoxey.toast.AndroidPlugin", currentActivity);

        androidPlugin.Call("ToastMakeText", message);

    }
