我已经用Wifi广播接收器开发了一个应用程序。我的要求是在Wifi通过获取IP地址连接到路由器时获得功能调用，以及当Wifi与先前连接的路由器断开连接时调用另一个函数。

--我在Manifest中使用了这个

<action android:name="android.net.wifi.STATE_CHANGE" />

用于注册广播接收器。

在OnReceive中的广播接收类中：

NetworkInfo networkInfo = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
NetworkInfo.State state = networkInfo.getState(); 

if (state == NetworkInfo.State.CONNECTED) {

    WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    WifiInfo wi = wifiManager.getConnectionInfo();

    Log.e("++++WiFi Conected","++++WiFi Conected");

    Flags.wifiState = true;
    updateWifiSyncTrue(context);

    if (wi.getIpAddress() != 0) {
        intent = new Intent(context, ConnectionService.class);
        intent.putExtra("intentValue", "signalOn");
        intent.putExtra("bssId", wi.getBSSID());
        context.startService(intent);
    }
}

if (state == NetworkInfo.State.DISCONNECTED) {
    Log.e("++++WiFi DisConected","++++WiFi DisConnected");
    Flags.wifiState = false;
    updateWifiSyncFalse(context);
    updateRouterSyncFalse(context);

    intent = new Intent(context, ConnectionService.class);
    intent.putExtra("intentValue", "signalOff");
    context.startService(intent);
}

每样东西都能工作到KitKat为止，但是当我用棒棒糖版本进行测试时，收到了很多次请求。

当我把我的WiFi打开其结果的为状态时:空闲--连接有时也会断线。

同时关闭。连接--断开--断开

NetworkInfo 的调试结果如下所示：
