1.Overview

HUAWEI Game Kit provides APIs to help you quickly implement the interaction between the game app and the system, by sending game data to the system and obtaining device status information from the system.

2.Application Scenarios

HUAWEI Game Kit optimizes gameplay experience, by letting your app interact with the system to apply different resource allocation strategies based on the game scene and system running status.

3.Instructions

3.1 Process Overview

3.2 Development Procedure

3.2.1 Obtaining Objects

private GameManager mGameKit = GameManager.getGameManager();

3.2.2 Registering an App with a Device

Register your app with the device in either of the following ways.

If you need to listen to device information changes through callback:

private GameCallBack gameSdkCallBack = new GameCallBack() { 
     @Override 
     public void onPhoneInfoUpdated(String info) { 
         Log.i(TAG, "onPhoneInfoUpdated: " + info); 
     } 
 }; 
boolean isSuccess = mGameKit.registerGame(packageName, gameSdkCallBack);

If you do not need to listen to device information changes through callback:

boolean isSuccess = mGameKit.registerGame(packageName, null);

3.2.3 Sending Messages to the Device

JSONObject jsonObject = new JSONObject(); 
try { 
     jsonObject.put("MessageType", 3); 
     jsonObject.put("SceneID", 1); 
     jsonObject.put("Description", "Game Start"); 
     jsonObject.put("ImportantLevel", 2); 
     jsonObject.put("Status", 1); 
     jsonObject.put("RecommendFps", 60); 
     jsonObject.put("KeyThread", "net|6001"); 
     String message = jsonObject.toString(); 
     mGameKit.updateGameAppInfo(message); 
     } catch (JSONException e) { 
     // Process exception 
}

3.2.4 Obtaining Device Information

String phoneInfo = mGameKit.getPhoneInfo();

3.2.5 Listening to Device Information Changes Through Callback

To listen to device information changes through callback, please refer to section 3.2.2.

To change the callback API, call registerGame(). After the callback API is changed, the previously registered listener does not take effect.

4.App Release

Self-check the app before release.

Run the automatic check by referring to Self-check Before Release, and modify your app based on the check report.

Read the release guidelines.

Before releasing your app, read the following for the guidelines and FAQs you may need to know:
