android-WifiManager.getConfiguredNetworks始终返回空列表

我正在尝试连接到开放的wifi网络.当我打开我的应用程序时,应打开wifi并连接到如下定义的网络.问题是WifiManager.getConfiguredNetworks总是向我返回一个空列表.我也尝试过使用锁,但没有成功.

WifiConfiguration conf = new WifiConfiguration();
conf.SSID = "\"" + networkSSID + "\"";
conf.status = WifiConfiguration.Status.ENABLED;        
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
conf.priority = Integer.MAX_VALUE;

WifiManager wifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE); 
wifiManager.setWifiEnabled(true);   
wifiManager.addNetwork(conf);


List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
if(list.isEmpty()) 
{
    Log.e("Connection Setup","Empty list returned");
}

for( WifiConfiguration i : list ) {
    if(i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) {
    Log.e("Connection Setup",i.SSID+" connrction attempted");
    wifiManager.disconnect();
    wifiManager.enableNetwork(i.networkId, true);
    wifiManager.reconnect();               
    break;
 }           
}

我一直在尝试更多的事情-如果让该线程休眠约10秒钟-一切正常,但是还有更好的选择吗？

解决方法:

您无法继续

CMD wifiManager.getConfiguredNetworks()

直到完全启用WiFi状态.要启用WiFi,需要一些时间.因此,您需要延迟一些时间.
