我正在工作的Wifi项目,有一个模块,使用户可以编程加入WiFi.
在kitkat和以下它正在成功工作,但在Lollipop它不工作.
这是代码：
WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wifiConfiguration = new WifiConfiguration();
wifiConfiguration.SSID = "\"testSSID\"";
wifiConfiguration.hiddenSSID = true;
wifiConfiguration.status = WifiConfiguration.Status.ENABLED;
wifiConfiguration.allowedKeyManagement
.set(WifiConfiguration.KeyMgmt.NONE);
netId = wifiManager.addNetwork(wifiConfiguration);
Log.d("WifiPreference","add Network returned " + netId);
boolean checkEnableWifi = wifiManager.enableNetwork(netId,true);
Log.d("WifiPreference","enableNetwork returned " + checkEnableWifi);
我的测试设备是nexus 5 build number LRX21O,在我的代码或Lollipop上的错误中有什么问题吗？
解决方法
面对类似的棒棒糖问题.
手动禁用其他网络,然后重新连接的WiFi管理器解决了这个问题.
boolean enableNework(String ssid,Context cxt) {
boolean state = false;
WifiManager wm = (WifiManager) cxt.getSystemService(Context.WIFI_SERVICE);
if (wm.setWifiEnabled(true)) {
List<WifiConfiguration> networks = wm.getConfiguredNetworks();
Iterator<WifiConfiguration> iterator = networks.iterator();
while (iterator.hasNext()) {
WifiConfiguration wifiConfig = iterator.next();
if (wifiConfig.SSID.equals(ssid))
state = wm.enableNetwork(wifiConfig.networkId,true);
else
wm.disableNetwork(wifiConfig.networkId);
}
wm.reconnect();
}
return state;
}
