    <p><em>1</em> Disconnecting internet cables is irrelevant. Use F8 to switch off/on internet in the emulator</p> <p><em>2</em> In the first code this logic is wrong:</p> <pre><code>if(info != null || info.isConnected()) { Log.v("NetworkInfo","Connected State"); } </code></pre> <p>It should be:</p> <pre><code>if(info != null &amp;&amp; info.isConnected()) { Log.v("NetworkInfo","Connected State"); } </code></pre> <p>If you use || then this is the result: a) when info is null, info.isConnected() will crash b) when info is not null, you will always show Connected State</p> <p>However, even if you fix that, the code wont be completely correct (see <em>4</em>)</p> <p><em>3</em> In the second code, this logic is wrong:</p> <pre><code> else if ( conMgr.getNetworkInfo(1).getState() == NetworkInfo.State.DISCONNECTED || conMgr.getNetworkInfo(0).getState() == NetworkInfo.State.DISCONNECTED) { Log.v("conMgr"," No Connection"); } </code></pre> <p>should be:</p> <pre><code> else { Log.v("conMgr"," No Connection"); } </code></pre> <p>Why? Because there are more states than CONNECTED and DISCONNECTED.</p> <p>However, even if you fix that, the code wont be completely correct (see <em>4</em>)</p> <p><em>4</em> This works on emulator and devices. </p> <pre><code>connected = ( conMgr.getActiveNetworkInfo() != null &amp;&amp; conMgr.getActiveNetworkInfo().isAvailable() &amp;&amp; conMgr.getActiveNetworkInfo().isConnected() ) </code></pre> <p>Note the use of isAvailable - without this isConnected can return TRUE when WIFI is disabled.</p> <p>Hope this helps!</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
