Unity获取当前手机网络状态与网络时间解析

获取网络状态的本来打算用unity网络属性Application.internetReachability,但是看到有一篇文章说在Android上在运行过程中不能获取准确的状态,只能在APP运行开始时才能获取,IOS倒是可以,所以笔者放弃了这种方法,转用Android原生的广播方法实现,如果不清楚unity与Android交互请看这里

（1）在AndroidManifest.xml配置文件中声明

<receiver android:name=".NetworkConnectChangedReceiver" >
            <intent-filter>
                <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
                <action android:name="android.net.wifi.WIFI_STATE_CHANGED" />
                <action android:name="android.net.wifi.STATE_CHANGE" />
            </intent-filter>
        </receiver>

（2）在代码中注册

IntentFilter filter = new IntentFilter();
        filter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
        filter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
        filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
        registerReceiver(new NetworkConnectChangedReceiver(), filter);

接下来创建实时监听网络连接与断开状态变化的BroadcastReceiver对象，我们需要继承android.content.BroadcastReceiver，并实现其onReceive方法，下面我们就创建一个名为NetworkConnectChangedReceiver广播接收者，看一下具体的实现代码

package ylcx.com.blue;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.net.wifi.WifiManager;
import android.os.Parcelable;
import android.util.Log;

public class NetworkConnectChangedReceiver extends BroadcastReceiver {
    private void ConnectNet(int type) {
        String connType = "";
        if (type == ConnectivityManager.TYPE_MOBILE) {
            connType = "3G网络数据";
        } else if (type == ConnectivityManager.TYPE_WIFI) {
            connType = "WIFI网络";
        }
        Log.d("TAG", connType + "连接");
    }
    private void DisconnectNet(int type)
    {
        String connType = "";
        if (type == ConnectivityManager.TYPE_MOBILE) {
            connType = "3G网络数据";
        } else if (type == ConnectivityManager.TYPE_WIFI) {
            connType = "WIFI网络";
        }
        Log.d("TAG", connType + "断开");
    }
    @Override
    public void onReceive(Context context, Intent intent) {
        if (WifiManager.WIFI_STATE_CHANGED_ACTION.equals(intent.getAction())) {// 监听wifi的打开与关闭，与wifi的连接无关
            int wifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, 0);
            switch (wifiState) {
                case WifiManager.WIFI_STATE_DISABLED:
                    break;
                case WifiManager.WIFI_STATE_DISABLING:
                    break;
            }
        }
        //监听wifi的连接状态即是否连上了一个有效无线路由
        if (WifiManager.NETWORK_STATE_CHANGED_ACTION.equals(intent.getAction())) {
            Parcelable parcelableExtra = intent
                    .getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
            if (null != parcelableExtra) {
                // 获取联网状态的NetWorkInfo对象
                NetworkInfo networkInfo = (NetworkInfo) parcelableExtra;
                //获取的State对象则代表着连接成功与否等状态
                NetworkInfo.State state = networkInfo.getState();
                //判断网络是否已经连接
                boolean isConnected = state == NetworkInfo.State.CONNECTED;
                if (isConnected) {
                } else {

                }
            }
        }
        // 监听网络连接，包括wifi和移动数据的打开和关闭,以及连接上可用的连接都会接到监听
        if (ConnectivityManager.CONNECTIVITY_ACTION.equals(intent.getAction())) {
            //获取联网状态的NetworkInfo对象
            NetworkInfo info = intent
                    .getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);
            if (info != null) {
                //如果当前的网络连接成功并且网络连接可用
                if (NetworkInfo.State.CONNECTED == info.getState() && info.isAvailable()) {
                    if (info.getType() == ConnectivityManager.TYPE_WIFI
                            || info.getType() == ConnectivityManager.TYPE_MOBILE) {
                        ConnectNet(info.getType());
                    }
                } else {
                   DisconnectNet(info.getType());
                }
            }
        }
    }
}

网络时间请看参考文章,很详细了
