Teach you high-speed and efficient access to the Sdk--unity Unified Access Channel SDK (Android)

U8SDK's design was designed to support games developed by a variety of game engines, not just Android's native platform. At the moment more than half hand tour, are adopted with Unity3d and COCOS2DX development, then here, we first step to show you, with unity development game, how to through the U8SDK to complete the multi-channel SDK access.

Unity Research and development of the hand tour, only need to call U8SDK abstraction layer can be completed multiple channels SDK access. Instead of coupling the various channel SDKs in unity, the logic layer of the game layer is simple, and the SDK section is absolutely reusable. Below, let's look at the main tasks required to call U8SDK in unity: 1. Establish a androidproject, as the intermediate coordination Project2 of U8SDK and Unity platform communication, and define a consistent communication data type, we use JSON format 3, In unity, a unified set of SDK invocation interfaces is completed through C #. Called to the logical layer. At the same time, multiple platforms (ANDROID,IOS,PC, etc.) interface completely the same.

This article. We're going to finish the first and second steps. 1, create a new Androidproject, and set Islibrary to True. Use this project as a library project so that when you compile, a jar package is generated under the Bin folder. Instead of a APK2, set dependent project for the U8SDK2 Abstraction Layer project, the same time the Unity3d provided by the Android jar package, copied to the project's Libs folder under 3, and then build two classes, One for U8unitycontext, this class inherits Unityplayeractivity. It is also the start activity of the game.

4, there is a Iu8sdklistener implementation class, the main implementation of some of the SDK callback methods we first look at the implementation of these two classes. And then we'll explain some of the key things:

This interface is mainly used for stand-alone games. As a single-machine payment result callback interface @overridepublic void Onpayresult (payresult result) {//todo}private void tip (Final String tip) { U8sdk.getinstance (). Runonmainthread (New Runnable () {@Overridepublic void run () {Toast.maketext (context, Tip, Toast.length_short). Show ();}});}}

In U8unitycontext, we define a series of interfaces. These interfaces are called in unity.

For example, Login,switchlogin,logout. The methods themselves, however, do a simple package for the method provided by the U8SDK abstraction layer. By, U8sdk.getinstance (). Runonmainthread () to have all of the interfaces complete in the UI main thread.

There are two parts to the initialization of U8SDK. The first part is the initialization of the U8SDK itself, including the reading and parsing of the parameters, which requires the android:name of the application interface in the Androidmanifest.xml to be set to "Com.u8.sdk.U8Application". Note that this must be set, otherwise u8sdk cannot be initialized. Assume that the game has its own certain business needs to be completed in application, can be completed by implementing the Iapplicationlistener interface provided by U8SDK. The second part needs to be completed in the activity's OnCreate (depending on the game, it is also possible to invoke the initialization interface in the appropriate place in unity), include, set the U8SDK callback listener, initialize the load plug-in, and invoke the OnCreate callback. The following three steps are performed: U8sdk. getinstance(). Setsdklistener ( NewUnityu8sdklistener ( This)); U8sdk. getinstance(). Init ( This); U8sdk. getinstance(). OnCreate (); Unityu8sdklistener is the implementation class for U8SDK's callback simplified interface. All SDK-related callbacks are completed through these interfaces.

ONLOGINRESULT:SDK Login Successful callback ONSWITCHACCOUNT:SDK switch account callback ONLOGOUT:SDK logout callback Onauthresult:u8server login authentication callback on Result: All SDK operation succeeded or failed status callback when we receive a partial callback, we need to notify unity before it is included. The interfaces we write, such as pay and submitextradata, are all of the parameters. Here's how to solve the data structure problems of communication in unity and Android. Although Unity and Android communication can also use complex structures, I recommend using a simple, unified data protocol. Here we choose JSON. Simple and efficient. Just to be sure. The key on both sides of the data will be consistent. Unity calls the Android interface, for example, pay and Submitextradata are passed through a JSON string, which is then parsed here.

For Android, it is also necessary to notify unity in the same way, using a JSON-formatted string and then passing Unityplayer. Unitysendmessage(Gameobject, MethodName, Jsonparams) interface to complete the communication. All right, over this, part of Android, it's over. Again, do not forget to configure Androidmanifest.xml Oh, here is attached androidmanifest.xml file:

<manifest xmlns:android= "http://schemas.android.com/apk/res/android" package= "COM.U8.SDK" android:versioncode= "1" android:versionname= "1.0" > <uses-sdk android:minsdkversion= "8" android:targetsdkversion= "21 "/> <application android:allowbackup=" true "android:icon=" @drawable/ic_launcher "Android:la                Bel= "@string/app_name" android:theme= "@style/apptheme" android:name= "Com.u8.sdk.U8Application" >             <activity android:name= "Com.u8.sdk.U8UnityContext" android:label= "@string/app_name" android:screenorientation= "Landscape" android:launchmode= "Singletask" android:configchanges= "O Rientation|keyboardhidden|screensize "> <intent-filter> <action android:n            Ame= "Android.intent.action.MAIN"/> <category android:name= "Android.intent.category.LAUNCHER"/> </intent-filteR> </activity> </application></manifest> 

Next. We need to be in unity to complete the next work, to be able to see the visit here: Unity Hand Tour access Channel SDK (Unity article)
