Description

This class can be used to implement any java interface. Any java vm method invocation matching the interface on the proxy object will automatically be passed to the c# implementation.

Note: this API can be used from custom thread, but requires that thread to be attached to JVM first, see AndroidJNI.AttachCurrentThread.

// Opens an android date picker dialog and grabs the result using a callback.
using UnityEngine;
using System;

class ExampleClass : MonoBehaviour { private static DateTime selectedDate = DateTime.Now;

class DateCallback : AndroidJavaProxy { public DateCallback() : base("android.app.DatePickerDialog$OnDateSetListener") {} void onDateSet(AndroidJavaObject view, int year, int monthOfYear, int dayOfMonth) { selectedDate = new DateTime(year, monthOfYear + 1, dayOfMonth); } }

void OnGUI() { if (GUI.Button(new Rect(15, 15, 450, 75), string.Format("{0:yyyy-MM-dd}", selectedDate))) { AndroidJavaClass activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaClass>("currentActivity"); activity.Call("runOnUiThread", new AndroidJavaRunnable(() => { new AndroidJavaObject("android.app.DatePickerDialog", activity, new DateCallback(), selectedDate.Year, selectedDate.Month - 1, selectedDate.Day).Call("show"); })); } } }
