Android, automatically connecting to wifi networks

问题:

I'm calling the function WifiManager.addNetwork(WifiConfiguration) to try and add an adhoc wifi network to the device's wifi configurations. But on Android M this function returns -1, I'm assuming because it doesn't have internet access. It works fine on most other devices. Below is code snippet I'm using.

WifiConfiguration wifiConfiguration = new WifiConfiguration(); wifiConfiguration.SSID = '\"' + ssid + '\"'; wifiConfiguration.hiddenSSID = false; wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); wifiManager.addNetwork(wifiConfiguration);

Any way to get around the internet connectivity check and force the network to be added?

You need to enable the network after that :

List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
for( WifiConfiguration i : list ) {
    if(i.SSID != null && i.SSID.equals("\"" + ssid + "\"")) {
         wifiManager.disconnect();
         wifiManager.enableNetwork(i.networkId, true);
         wifiManager.reconnect();               
    enter code here
         break;
    }           
 }
