Unity 第三方SDK框架接入 (Android Studio）

第三方SDK框架接入 (Android Studio）一 Android

Android 與 Unity 交互：

 UnityPlayer.UnitySendMessage("string","string", var2); 

UnitySendMessage（“string”，“string”， ***），這是方法，我們至少需要傳入兩個參數，第一個參數爲unity中的一個gameobject名稱，第二個參數爲這個gameobject身上捆綁的腳本中的一個方法，而第三參數事實上是這個對應方法上的參數，有沒有參數就看你自己的需求了

Unity 與 Android

 	private AndroidJavaObject GetAndroidJavaObject()
    {
        AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        return jc.GetStatic<AndroidJavaObject>("currentActivity");
    }

    private AndroidJavaObject sdk
    {
        get { return _sdk ?? (_sdk = GetAndroidJavaObject()); }
    }

    private AndroidJavaObject _sdk;
    
    public void ShowToolBar()
    {
        sdk.Call("requestShowToolBar");
    }

Call 方法和 UnitySendMessage 方法都是固定的形式，只是參數不一樣而已。想了解更深的東西自行百度吧。

新建一個Library

我們採用Android Studio 打包成jar給Unity項目。怎麼操作，百度一大堆，這裏就不描述了。
1.新建一個Library


這裏說明一下，我們需要把unity的classes.jar文件添加到我們的libs引用中去，因爲我們的Activity需求繼承於UnityPlayerActivity才能實現和Android 和 unity 之間的交互。

新建MyActivity類

package com.example.unitylibrary;

import com.unity3d.player.UnityPlayerActivity;

MyActivity 類 提供底層的所有接口。功能不在這個類實現。他只是負責接口的調度。我們新建一個實現接口的APL類。

API類的理解：

API主要是實現MyActivity的接口，接入第三方SDK的相關代碼都在這裏完成，如： 初始化，登錄，支付 ，信息上傳等等，
接SDK的時候，幾乎都是抄代碼，你只需要寫好一個模板。根據第三方的文檔對着抄就可以了。

導出jar

雙擊exportJar等待生產的AndroidPlugin.jar文件，將他拷貝到unity的Plugins/Android目錄下。
