    <p>I've written an application to easily connect Android devices to our company's various wireless networks. It is intended to be run once, when the device is unboxed and set up with the rest of our application suite.</p> <p>The problem is that sometimes, the device will forget the networks without being told to do so. I have not been able to reproduce this, unfortunately. I'm hoping that I've missed some API call that the Android gurus here can help me find.</p> <p>The code that follows is from my run-once wireless initialization app, with the network names and keys changed. Can anyone see something I'm doing incorrectly here?</p> <p>Edit: The device that I have observed this behavior on is the LG Ally. I'm hoping it's a bug with my own code, so that's where I'm starting.</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { WifiConfiguration n1Config = new WifiConfiguration(); n1Config.SSID = "\"networkOne\""; n1Config.preSharedKey = "\"...\""; n1Config.status = WifiConfiguration.Status.ENABLED; WifiConfiguration n2Config = new WifiConfiguration(); n2Config.SSID = "\"networkTwo\""; n2Config.hiddenSSID = true; n2Config.wepKeys[0] = "..."; n2Config.wepTxKeyIndex = 0; n2Config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); n2Config.allowedProtocols.set(WifiConfiguration.Protocol.RSN); n2Config.allowedProtocols.set(WifiConfiguration.Protocol.WPA); n2Config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN); n2Config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED); n2Config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP); n2Config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP); n2Config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40); n2Config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104); n2Config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); n2Config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); n2Config.status = WifiConfiguration.Status.ENABLED; WifiManager wifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE); int n1ID = wifiManager.addNetwork(n1Config); wifiManager.enableNetwork(n1ID, false); int n2ID = wifiManager.addNetwork(n2Config); wifiManager.enableNetwork(n2ID, false); } </code></pre>

    1. COCould it be something as simple as there may be a finite number of networks that Android can remember? Example, Android will only remember X number of networks and under certain circumstances if a user goes within range of X networks since last using your company network, your network gets pushed out of the network 'cache'. Admittedly it seems unlikely but could be tested fairly easily.

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.
