java翻译到mono C#实现系列(3) 获取手机设备信息(残缺,)

            TelephonyManager telphoneMgr = (TelephonyManager)GetSystemService(Context.TelephonyService);
            string Imei = telphoneMgr.DeviceId;//IMEI号.需要READ_PHONE_STATE权限
              string PhoneType = telphoneMgr.PhoneType.ToString();//手机网络制式,例如GSM
            string str0 = telphoneMgr.NetworkType.ToString();//网络模式 "Hspa"
            string PhoneNum = telphoneMgr.Line1Number;//手机号
              string SdkVersion = telphoneMgr.DeviceSoftwareVersion;//IMEI SV
            string ReleaseVersion = telphoneMgr.NeighboringCellInfo.ToString();//未知,安卓是获取周围基站的信息　getNeighboringCellInfo
                                                                                //需要ACCESS_COARSE_LOCATION权限
              string str1 = telphoneMgr.CallState.ToString();//电话状态:CALL_STATE_IDLE=0无活动,CALL_STATE_RINGING=1响铃24,CALL_STATE_OFFHOOK=2摘机
              CellLocation str2 = telphoneMgr.CellLocation;//电话定位
              DataActivity str3 = telphoneMgr.DataActivity;
            TextView txtimei = FindViewById<TextView>(Resource.Id.imei);
            txtimei.Text = Imei; 
            //button.Click += delegate { button.Text = string.Format("{0} clicks!", count++); };
        }
    }
}

调试android程序出现异常：

java.lang.SecurityException:requires READ_PHONE_STATE

根据异常提示，发现是手机的设备号获取失败

异常原因：AndroidMinifest.xml中没有添加READ_PHONE_STATE权限

解决法案：修改AndroidMinifest.xml，在<application/>之后添加权限设置

Androidmainfest.xml代码

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

总结：Security 英文翻译“安全，安全的”，顾名思义SecurityException就是指安全异常，容易联想到是权限限

制导致的异常，手机软件对权限的限制是很多的，后面requires READ_PHONE_STATE一目了然就是要求READ_PHONE_STATE

这个权限

另外在虚拟机如果获取不到部分信息,请到真实机子调试.
