unity_oaid: A C# repository from nbachenxiao

最近一个项目要对接一个sdk, 里面要求传入imei, 没有imei的传入oaid。看了一下oaid的官网，无论下载还是看文档都要注册等审核，等不了。直接从别的地方下载了oaid的sdk开始弄。可惜网上没有太多的可以参考的东西，有一篇写的很详细的在unity中使用oaid的文章，但是操作方法太复杂了，因为用的是unity5所以对java的调用极其繁琐。用了小半天时间弄好了，现在记录一下方法。

1、下载oaid sdk, 解压，里面有用的是一个aar文件，一个json文件

2 、在unity Assets中创建Plugins\Android目录，把aar文件拷贝到这个目录。再在Plugins\Android目录下创建一个assets目录，把json文件拷贝进去。

3、在Plugins\Android目录下创建一个java文件，我的文件如下：

package com.unity.androidplugin;

import android.content.Context; import android.util.Log;

import com.bun.miitmdid.core.MdidSdkHelper; import com.bun.miitmdid.interfaces.IIdentifierListener; import com.bun.miitmdid.interfaces.IdSupplier; import com.unity3d.player.UnityPlayer;

public class OAIDHelper implements IIdentifierListener {

String cbGameObject = "";
String cbFunc = "";

public static OAIDHelper _inst = null;

public OAIDHelper(){
    _inst = this;
}

public static OAIDHelper inst(){
    if (_inst == null){
        _inst = new OAIDHelper();
    }
    return _inst;
}

public int GetDeviceID(Context cxt, String gameObject, String cbFunc){
    cbGameObject = gameObject;
    this.cbFunc = cbFunc;

    int r = MdidSdkHelper.InitSdk(cxt, true, this);

    Log.i("GetDeviceID", "obj: " + cbGameObject + " cb:" + cbFunc + " init:" + r);

    return r;
}

/** 获取id回调 */
@Override
public void OnSupport(boolean b, IdSupplier idSupplier) {
    if(idSupplier != null) {
        String oaid = idSupplier.getOAID();
        if(!cbGameObject.isEmpty() && !cbFunc.isEmpty()){
            UnityPlayer.UnitySendMessage(cbGameObject, cbFunc, oaid == null ? "" : oaid);
        }
        Log.i("GetDeviceID", "OnSupport: " + b + " id: " + (oaid == null ? "" : oaid));
    } else {
        Log.i("GetDeviceID", "OnSupport IdSupplier null");
        if(!cbGameObject.isEmpty() && !cbFunc.isEmpty()){
            UnityPlayer.UnitySendMessage(cbGameObject, cbFunc, "");
        }
    }
}

} 其中要注意两点，包名是package com.unity.androidplugin，类必须继承自IIdentifierListener。使用时直接调用MdidSdkHelper.InitSdk，看返回结果，目前只有结果为ErrorCode.INIT_ERROR_RESULT_DELAY才是执行成功了，此时等待OnSupport调用，用idSupplier取出oaid。

4、C#部分代码如下：

using System; using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.Android;

public class DeviceIDHelperObject : MonoBehaviour { Action cbFunc = null; float timer = 0; bool waiting = false;

Func<bool> condition = null;
Action<bool> runFunc = null;
float tiemrWaitFor = 0;

public void setCbFunc(Action<string> cbFunc)
{
    this.cbFunc = cbFunc;
}

public void waitResult(float timeout = 5)
{
    timer = timeout;
    waiting = true;
}

public void onOAIDRecv(string oaid)
{
    if (cbFunc != null && waiting)
    {
        cbFunc(oaid);
        waiting = false;
        timer = 0;
    }
}

public void waitFor(Func<bool> c, Action<bool> f, float timeout = 30)
{
    condition = c;
    runFunc = f;
    tiemrWaitFor = timeout;
}

private void Update()
{
    if (timer > 0)
    {
        timer -= Time.deltaTime;
        if (timer <= 0)
        {
            waiting = false;
            timer = 0;
            if (cbFunc != null)
            {
                cbFunc("");
            }
        }
    }

    if ( condition != null && runFunc != null)
    {
        if (condition())
        {
            runFunc(true);
            condition = null;
            runFunc = null;
            tiemrWaitFor = 0;
        }
        if (tiemrWaitFor > 0)
        {
            tiemrWaitFor -= Time.deltaTime;
            if (tiemrWaitFor <= 0)
            {
                runFunc(false);
                condition = null;
                runFunc = null;
                tiemrWaitFor = 0;
            }
        }
    }
}

}

        cbFunc(err, new string[] { SystemInfo.deviceUniqueIdentifier });

}

使用方法：

    logdb.text = "";
    DeviceIDHelper.inst.getDeviceID((err, res) =>
    {
        if (err != null)
        {
            logdb.text = err.Message + "\r\n";
        }

        foreach(var v in res)
        {
            logdb.text += "id: " + v + "\r\n";
        }
    });

正常情况可以取出imei， android10以上会尝试取出oaid，出错时返回SystemInfo.deviceUniqueIdentifier的值。
