cocos2d-x获取设备信息-优快云博客

本文介绍了一种使用C++在Android和iOS平台上获取设备信息的方法，包括设备型号、操作系统版本、电话号码等。对于Android平台，通过JNI调用Java代码实现；对于iOS平台，则直接使用Objective-C和Swift进行获取。

DeviceUtils.java

Android端的具体实现

package com.easygo.games.utils;

import android.content.Context;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.os.Build;
import android.telephony.TelephonyManager;

/**
 * Device Utils
 * Created by song on 14-8-20.
 */
public class DeviceUtils {

    public static Context context;

    public static String getModel() {
        return Build.MODEL;
    }

    public static String getPhoneNumber() {
        TelephonyManager phoneMgr = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
        return phoneMgr.getLine1Number();
    }

    public static int getSdkVersion() {
        return Build.VERSION.SDK_INT;
    }

    public static String getOsVersion() {
        return Build.VERSION.RELEASE;
    }

    public static String getPackageVersionName() {
        try {
            PackageInfo packageInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0);
            if (null != packageInfo) {
                return packageInfo.versionName;
            }
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
        return "";
    }
}

Android获取本机号码，需要在AndroidManifest.xml中添加权限：

<uses-permission android:name=”android.permission.READ_PHONE_STATE” />
