android cocoscreator 检测模拟器还是真机

具体原理看原博主文章，这里只讲cocoscreator3.6的安卓工程怎么使用

1.新建一个com.lahm.library包，和com.cocos.game同目录，如图示

那四个文件的代码如下：

复制代码

EmulatorCheckUtil类，检测模拟器和真机的工具类，是入口：

关键是 readSysProperty这个方法，返回false就不是模拟器是真机，true是模拟器

此包内的四个文件如下：

    public static final int RESULT_MAYBE_EMULATOR = 0;//可能是模拟器
    public static final int RESULT_EMULATOR = 1;//模拟器
    public static final int RESULT_UNKNOWN = 2;//可能是真机

    public int result;
    public String value;

    public CheckResult(int result, String value) {
        this.result = result;
        this.value = value;
    }
}

EmulatorCheckCallback接口

java 复制代码

package com.lahm.library;

/**
 * Project Name:EasyProtector
 * Package Name:com.lahm.library
 * Created by lahm on 2018/7/25 15:19 .
 */
public interface EmulatorCheckCallback {
    void findEmulator(String emulatorInfo);
}

在cocos.game.AppActivity这个类里，先声明一个静态变量：

public static boolean isEnumator = false;

在onCreate(Bundle savedInstanceState)方法里这样调用：

this.isEnumator = EmulatorCheckUtil.getSingleInstance().readSysProperty(this, null);

这样就能检测出模拟器还是真机了，为true就是模拟器，false为真机。

再写个方法给typescript层调用：

java 复制代码

public static boolean isRunningOnEmulator() {
        return isEnumator;
    }

typescript层这样调用即可：

java 复制代码

getEmulator() { //检查是否是模拟器
        if(native.reflection) {
            global.bEmulator =  native.reflection.callStaticMethod("com/cocos/game/AppActivity", "isRunningOnEmulator","()Z");
        }
        else
            global.bEmulator = false;
    }

大功告成，实测夜神模拟器，蓝叠模拟器能检测出来。
