android on connect to network listener后台

在版本（7.0）之后，最好的方法是什么 我使用“BroadcastReceiver”进行此操作，但在版本（7.0）之后，问题开始出现 我尝试使用“GcmTaskService”和“JobScheduler” 但是我没有找到正确的路。 有人能帮我吗？

RxAndroid（）为响应异步进程提供了非常有用的工具

特别是关于网络连接，您可以使用内置的android NetworkManager和Wific配置开始连接，并使用RxAndroid反应网络静态方法观察连接

WifiConfiguration wifiConfig = new WifiConfiguration();
conf.ssid = "\"SecureNetwork\"" //Note that quote characters are required in the SSID
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);

WifiManager wifiManger = (WifiManager) appContext.getSystemService(Context.WIFI_SERVICE);
if (wifiManager == null) {
    //error handling - make sure you have permissions etc
}

int connectionId = wifiManager.addNetwork(conf);
if (connectionId == -1) {
    //Network is already configured - find configuration using wifiManger.getConfiguredNetworks();
}

wifiManager.enableNetwork(connectionId, true); //Attempt to connect to network

//Now use RxAndroid ReactiveNetwork to observe connectivity

ReactiveNetwork.observeNetworkConnectivity(context)
    .filter(ConnectivityPredicate.hasState(NetworkInfo.State.CONNECTED))
    .filter(ConnectivityPredicate.hasType(ConnectivityManager.TYPE_WIFI))
    .flatMap(connectivity -> {
        int currentNetId = wifiManager.getConnectionInfo().getNetworkId();
        if (currentNetId == connectionNetId) {
             return Observable.just(true);
        } else {
             return Observable.error("Not connected to new network")
        }
    .doOnNext(mBoolean -> //Do whatever you want to now that you are connect)
    .doOnError(mError ->> //Handle error)
    .suscribe();
