    <p>I have been using a small setup to check the bandwidth for determining how to scale things, such as images.</p> <p>Under the activity, in AndroidManifest:</p> <pre><code>&lt;intent-filter&gt; ... &lt;action android:name="android.net.conn.CONNECTIVITY_CHANGE"/&gt; &lt;/intent-filter&gt; </code></pre> <p>In the activity where the checks are being performed:</p> <pre><code>boolean network; int bandwidth; @Override public void onCreate(Bundle savedInstanceState) { ... network = isDataConnected(); bandwidth = isHighBandwidth(); registerReceiver(new BroadcastReceiver() { public void onReceive(Context context, Intent intent) { network = isDataConnected(); bandwidth = isHighBandwidth(); } }, new IntentFilter("android.net.conn.CONNECTIVITY_CHANGE")); ... } ... private boolean isDataConnected() { try { ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); return cm.getActiveNetworkInfo().isConnectedOrConnecting(); } catch (Exception e) { return false; } } private int isHighBandwidth() { ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo info = cm.getActiveNetworkInfo(); if (info.getType() == ConnectivityManager.TYPE_WIFI) { WifiManager wm = (WifiManager) getSystemService(Context.WIFI_SERVICE); return wm.getConnectionInfo().getLinkSpeed(); } else if (info.getType() == ConnectivityManager.TYPE_MOBILE) { TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); return tm.getNetworkType(); } return 0; } </code></pre> <p>An example usage would then be:</p> <pre><code>if (network) { if (bandwidth &gt; 16) { // Code for large items } else if (bandwidth &lt;= 16 &amp;&amp; bandwidth &gt; 8) { // Code for medium items } else { //Code for small items } } else { //Code for disconnected } </code></pre> <p>It's not the prettiest, but it allows enough flexibility that I can change the bandwidth cutoff for items depending on what they are and my requirements for them.</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.
