    <p>I am trying to write some code that will disconnect current wifi network (if any) and reconnect to a specific wifi network with known SSID.</p> <p>I have been following the code used here; <a href="https://stackoverflow.com/questions/8818290/how-to-connect-to-a-specific-wifi-network-in-android-programmatically">How do I connect to a specific Wi-Fi network in Android programmatically?</a></p> <p>which works but the connection takes several seconds, upto about 10 seconds.</p> <p>Specifically, I use the code as follows;</p> <pre><code>WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE); WifiConfiguration config; </code></pre> <p>I obtain the config, whether by creating a new one and setting the SSID and KeyMgmt to NONE and then adding it;</p> <pre><code>wifiManager.add(config); </code></pre> <p>or by getting a config that already exists;</p> <pre><code>List&lt;WifiConfiguration&gt; list = wifiManager.getConfiguredNetworks(); for( WifiConfiguration i : list ) { if(i.SSID != null &amp;&amp; i.SSID.equals("\"" + networkSSID + "\"")) { config = i; break; } } </code></pre> <p>Then I call;</p> <pre><code>wifiManager.disconnect(); wifiManager.enableNetwork(i.networkId, true); wifiManager.reconnect(); </code></pre> <p>I have a broadcast received checking the wifi state and when i get a connected for my correct SSID i can continue, however, this process takes upto 10 seconds, how can i set up the config or wifimanager to connect to this much quicker?</p> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
