Unity与Android交互
作者：互联网
Unity调用 Android代码
Unity版本：2019.4.30
1.将unity class.jar文件放入libs文件夹中
2.UnityPlayerActivity.java
3.UnityPlayerActivity.java里引入两个包
import com.unity3d.player.IUnityPlayerLifecycleEvents;
import com.unity3d.player.UnityPlayer;
4.AndroidManifest.xml 文件加入以下代码
<meta-data
android:name="unityplayer.UnityActivity"
android:value="true" />
package包名要与unity包名一致
5.gradle配置
因为要打包成aar包， 需要做以下修改
6.MainActivity中编写代码
package com.xingame.unitycallandroid;
import android.os.Bundle;
import android.widget.Toast;
import com.unity3d.player.UnityPlayer;
public class MainActivity extends UnityPlayerActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main);
}
//unity调用Android
public void UnityCallAndroid () {
Toast.makeText(this,"unity调用android成功", Toast.LENGTH_LONG).show();
AndroidCallUnity();
}
//android调用unity
public void AndroidCallUnity () {
//第1个参数为Unity场景中用于接收android消息的对象名称
//第2个参数为对象上的脚本的一个成员方法名称（脚本名称不限制）
//第3个参数为unity方法的参数
UnityPlayer.UnitySendMessage("receiveObj", "UnityMethod", "This is args.");
}
}
7.buid后将文件复制到unity对应文件中（这里不细说了了）
8.unity添加脚本，调用android（创建unity UI省略）
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class SDKTest : MonoBehaviour
{
private AndroidJavaClass jc;
private AndroidJavaObject jo;
private Button btn;
private static Text text;
private void Awake()
{
btn = transform.Find("Button").GetComponent<Button>();
text = transform.Find("Text").GetComponent<Text>();
btn.onClick.AddListener(OnBtnClickHandler);
}
private void OnBtnClickHandler()
{
using (jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer")){
using (jo = jc.GetStatic<AndroidJavaObject>("currentActivity")){
jo.Call("UnityCallAndroid");
}
}
}
/// <summary>
/// 被Android中AndroidCallUnity调用
/// </summary>
/// <param name="str"></param>
public void UnityMethod(string str)
{
Debug.Log("UnityMethod被调用，参数：" + str);
text.text = str;
}
}
Unity的AndroidJavaProxy的使用
android代码:
接口：
package com.xingame.unitycallandroid;
public interface TestInterface {
void func_1();
}
package com.xingame.unitycallandroid;
public class MainActivity2{
public static MainActivity2 instance;
private int numb = 0;
private TestInterface mTestInterface;
public void SetTestInterface(TestInterface testInterface){
mTestInterface = testInterface;
mTestInterface.func_1();
}
public static MainActivity2 GetInstance(){
if (instance==null){
return new MainActivity2();
}
return instance;
}
public int UnityCallAndroid2 () {
return numb;
}
}
unity代码：
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class SDKTest : MonoBehaviour
{
private AndroidJavaClass jc;
private AndroidJavaObject jo;
private Button btn;
private static Text text;
private static DateTime selectedTime = DateTime.Now;
public static Text info;
public class OnDateSetListener : AndroidJavaProxy
{
public OnDateSetListener() : base("android.app.DatePickerDialog$OnDateSetListener") { }
void onDateSet(AndroidJavaObject view, int year, int month, int dayOfMonth)
{
text.text = year + "/" + (month + 1) + "/" + dayOfMonth;
}
}
public class TestInterface : AndroidJavaProxy
{
public TestInterface() : base("com.xingame.unitycallandroid.TestInterface") { }
public void func_1()
{
info.text = "8888";
}
}
private void Awake()
{
btn = transform.Find("Button").GetComponent<Button>();
text = transform.Find("Text").GetComponent<Text>();
info = transform.Find("Info").GetComponent<Text>();
btn.onClick.AddListener(OnBtnClickHandler);
}
void Start()
{
AndroidJavaObject currentActivity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic<AndroidJavaObject>("currentActivity");
currentActivity.Call("runOnUiThread", new AndroidJavaRunnable(() =>
{
new AndroidJavaObject("android.app.DatePickerDialog", currentActivity, new OnDateSetListener(), selectedTime.Year, selectedTime.Month - 1, selectedTime.Day).Call("show");
}));
}
public void OnBtnClickHandler2()
{
//通过对象调用方法
/*using (jo = new AndroidJavaObject("com.xingame.unitycallandroid.MainActivity2")) {
text.text = jo.Call<int>("UnityCallAndroid2").ToString();
}*/
using (jc = new AndroidJavaClass("com.xingame.unitycallandroid.MainActivity2")) {
jo = jc.CallStatic<AndroidJavaObject>("GetInstance"); //通过类调用静态方法
jo.Call("SetTestInterface", new TestInterface());
}
}
}
unity调用Android 震动
android代码
public void UnityCallVibrate(int time){
Vibrate(this,time);
}
public static void Vibrate(final Activity activity, long milliseconds) {
Vibrator vib = (Vibrator) activity.getSystemService(Service.VIBRATOR_SERVICE);
vib.vibrate(milliseconds);
}
unity代码
#if UNITY_ANDROID&& !UNITY_EDITOR
AndroidJavaClass jc;
AndroidJavaObject jo;
#endif
private void Start()
{
#if UNITY_ANDROID && !UNITY_EDITOR
jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
#endif
}
private void Vibrate(int time)
{
#if UNITY_ANDROID && !UNITY_EDITOR
jo.Call("UnityCallVibrate", time);
#endif
}
unity调用Android Toast
unity代码
public void ToaskMakeTest(string str)
{
#if UNITY_ANDROID && !UNITY_EDITOR
AndroidJavaObject context = jo.Call<AndroidJavaObject>("getApplicationContext");
AndroidJavaClass toast = new AndroidJavaClass("android.widget.Toast");
jo.Call("runOnUiThread", new AndroidJavaRunnable(() =>
{
toast.CallStatic<AndroidJavaObject>("makeText", context, str, toast.GetStatic<int>("LENGTH_LONG")).Call("show");
}));
#endif
}
检测是否连接网络
android代码
public boolean IsHaveNetwork()
{
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = cm.getActiveNetworkInfo();
if (networkInfo == null || !networkInfo.isAvailable()) {
//没有联网
return false;
} else {
//有网络
return true;
}
}
unity代码
private bool currntNet = false;
#if UNITY_ANDROID && !UNITY_EDITOR
jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
#endif
public bool DetectionNetwork()
{
#if UNITY_ANDROID && !UNITY_EDITOR
//网络从无到有
if (currntNet != jo.Call<bool>("IsHaveNetwork") && currntNet == false)
{
currntNet = jo.Call<bool>("IsHaveNetwork");
}
return currntNet;
#else
return true;
#endif
}
