Unity调用Android封装的声网sdk

文章目录

unity3调用Android 封装的声网SDK

1、环境版本

unity3D 编辑器 2020

Android Studio 4.2

2、创建Android library 工程

3、unity3D 依赖包添加到工程libs下

依赖包的位置（unity 安装目录下）：E:\Unity_install\2020.3.28f1c1\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Release\Classes

4、UnityPlayerActivity 添加到项目中

5、自定义Activity 继承 UnityPlayerActivity

注销掉设置布局方法

6、清单文件设置

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.xyx.astounity">
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
    <application>
        <activity android:name="com.xyx.astounity.MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
         
            <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
        </activity>

    </application>

</manifest>

7、build.gradle 添加 jar 脚本

//----------------这是一组将module导出为jar的gradle命令-------------------
task deleteOldJar(type: Delete) {
    
    
    delete 'release/AndroidPlugin.jar'
}

//task to export contents as jar
task exportJar(type: Copy) {
    
    
    from('build/intermediates/aar_main_jar/release/')
    into('release/')
    include('classes.jar')
    ///Rename the jar
    rename('classes.jar', 'AndroidPlugin.jar')
}

exportJar.dependsOn(deleteOldJar, build)

8、集成声网sdk

8.1 so库添加到项目中

$[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-8H9jrOVH-1646983827613)(C:\Users\Administrator\AppData\Roaming\Typora\typora-user-images\image-20220225102511333.png)]$

8.2 声网jar 添加 libs 目录下

         * There are two reasons for users to become offline:
         *
         *     Leave the channel: When the user/host leaves the channel, the user/host sends a goodbye message. When this message is received, the SDK determines that the user/host leaves the channel.
         *     Drop offline: When no data packet of the user or host is received for a certain period of time (20 seconds for the communication profile, and more for the live broadcast profile), the SDK assumes that the user/host drops offline. A poor network connection may lead to false detections, so we recommend using the Agora RTM SDK for reliable offline detection.

         * @param uid ID of the user or host who
         * leaves
         * the channel or goes offline.

         *
         *     USER_OFFLINE_QUIT(0): The user left the current channel.
         *     USER_OFFLINE_DROPPED(1): The SDK timed out and the user dropped offline because no data packet was received within a certain period of time. If a user quits the call and the message is not passed to the SDK (due to an unreliable channel), the SDK assumes the user dropped offline.
         *     USER_OFFLINE_BECOME_AUDIENCE(2): (Live broadcast only.) The client role switched from the host to the audience.

        @Override

                        try {
    
    
                            isSpeak = true;

8.5 MainActivity中提供方法给 unity 调用

 public boolean  isIsSpeak(){
    
    
        if (voiceUtils==null){
    
    
            Toast.makeText(this,"对象没有初始化",Toast.LENGTH_SHORT).show();
            return false;
        }
        return voiceUtils.isIsSpeak();
    }


    public void initializeAgoraEngine(){
    
    
        voiceUtils.initializeAgoraEngine(this);
    }


    public void joinChannel(){
    
    
        if (voiceUtils==null){
    
    
            Toast.makeText(this,"对象没有初始化",Toast.LENGTH_SHORT).show();
            return;
        }

        voiceUtils.joinChannel();

    }

9、jar 生成

11、 unity 脚本中调用 android 提供的方法

unity的包名和Android的版本设置的和jar包的一样

初始化声网sdk的脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
#if(UNITY_2018_3_OR_NEWER)
using UnityEngine.Android;
#endif




public class CallAndroid : MonoBehaviour
{
    
    
    // Start is called before the first frame update
    void Start()
    {
    
    

        Permission.RequestUserPermission("android.permission.RECORD_AUDIO");

#if (UNITY_2018_3_OR_NEWER)
        if (Permission.HasUserAuthorizedPermission(Permission.Microphone))
        {
    
    
                
        }
        else
        {
    
    
            Permission.RequestUserPermission(Permission.Microphone);
        }
#endif

    }

    // Update is called once per frame
    void Update()
    {
    
    
        
    }

    private AndroidJavaClass jc;
    private AndroidJavaObject jo;


    private void OnGUI()
    {
    
    

        if (GUILayout.Button("Call Android",GUILayout.Width(200), GUILayout.Height(100)))
       
        {
    
    
            //这两行是固定写法
            jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            jo = jc.GetStatic<AndroidJavaObject>("currentActivity");

            int result =jo.Call<int>("add",1,2);
            jo.Call("UnityCallAndroid");



           // bool isSpeek = jo.Call<bool>("isIsSpeak");

             


        }


        if (GUILayout.Button("init", GUILayout.Width(200), GUILayout.Height(100)))

        {
    
    
            //这两行是固定写法
            jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            jo = jc.GetStatic<AndroidJavaObject>("currentActivity");

            jo.Call("initializeAgoraEngine");


        }


        if (GUILayout.Button("join", GUILayout.Width(200), GUILayout.Height(100)))

        {
    
    
            //这两行是固定写法
            jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
            jo = jc.GetStatic<AndroidJavaObject>("currentActivity");

            jo.Call("joinChannel");


        }

    }

    public void UnityMethod(string str)
    {
    
    
        Debug.Log("UnityMethod被调用，参数：" + str);
      
    }
}

判断声网sdk VAD 脚本

using System.Collections;
using System.Collections.Generic;
using System.Threading;
using UnityEngine;

public class Switch : MonoBehaviour
{
    
    
    // Start is called before the first frame update


    private AndroidJavaClass jc;
    private AndroidJavaObject jo;

    long currentTime=0;
    GameObject a;
    GameObject b;
    void Start()
    {
    
    
        a = GameObject.Find("a_demo");
        b = GameObject.Find("b");

    }


    bool flag=false;

    // Update is called once per frame
    [System.Obsolete]
    void Update()
    {
    
    



        //这两行是固定写法
        jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        jo = jc.GetStatic<AndroidJavaObject>("currentActivity");


        bool isSpeek = jo.Call<bool>("isIsSpeak");

        Debug.Log("isSpeek：：：：====" + isSpeek);
        Thread.Sleep(300);
        if (isSpeek)
        {
    
    
            //Thread.Sleep(200);

            a.SetActive(flag);
            b.SetActive(!flag);
            flag = !flag;
           
            Debug.Log("-----" + flag);
            // a.SetActive(true);
            // b.SetActive(false);
        }
        else {
    
    

            if (b.active)
            {
    
    
                b.SetActive(false);
                a.SetActive(true);
                flag = !flag;
            }

        }
      
        
    }
}
