cocos creater 没有带获取手机IEMI和设备id的接口，只能自己获取,需要修改原生的安卓代码才能获取。

可以参考官方文档：https://docs.cocos.com/creator/manual/zh/advanced-topics/java-reflection.html

获取IEMI需要开启权限获取设备id无需权限，所以建议获取设备id

首先构建项目，构建出安卓代码。

找到安卓代码里面的位置，我的文件地址是（\项目地址\build\jsb-link\frameworks\runtime-src\proj.android-studio\app\src\org\cocos2dx\javascript）

我这里是获取设备id的，无需开启权限，

获取设备id

修改AppActivity.java代码：

    @Override

        SDKWrapper.getInstance().onStart();
        super.onStart();

}

然后在cocos creater代码里面直接调用：

 //rtn 就是设备id，传参自己按照官方文档修改就行，，可以自己加标识
 var rtn = jsb.reflection.callStaticMethod("org/cocos2dx/javascript/AppActivity", "getIMEI2", "(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;", "title", "message");

如果需要获取IMEI

首先，添加安卓权限，我的项目地址：\项目地址\build\jsb-link\frameworks\runtime-src\proj.android-studio\app

找到AndroidManifest.xml 文件，添加权限

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

然后把获取imei函数注释修改一下，

    /**
     *
     * @param context
     * @return
     */
    public static String getIMEI(Context context) {
        // return  Settings.Secure.getString(context.getApplicationContext().getContentResolver(), Settings.Secure.ANDROID_ID);
        TelephonyManager manager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
//        TelephonyManager manager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
       try {
           Method method = manager.getClass().getMethod("getImei", int.class);
           String imei1 = (String) method.invoke(manager, 0);
           String imei2 = (String) method.invoke(manager, 1);
           if(TextUtils.isEmpty(imei2)){
               return imei1;
           }
           if(!TextUtils.isEmpty(imei1)){
               //因为手机卡插在不同位置，获取到的imei1和imei2值会交换，所以取它们的最小值,保证拿到的imei都是同一个
               String imei = "";
               if(imei1.compareTo(imei2) <= 0){
                   imei = imei1;
               }else{
                   imei = imei2;
               }
               return imei;
           }
       } catch (Exception e) {
//            e.printStackTrace();
           try {
               if (manager.getDeviceId() != null) {
                   return manager.getDeviceId().toString();
               } else {
                   return Settings.Secure.getString(context.getApplicationContext().getContentResolver(), Settings.Secure.ANDROID_ID);
               }
           } catch (Exception e2) {
               return Settings.Secure.getString(context.getApplicationContext().getContentResolver(), Settings.Secure.ANDROID_ID);
           }
       }
       return "";
    }

注意：为了防止没有授权app闪退，所以没授权 就获取设备id，所以一开始没有授权后面授权了，获取的id就会不一样
