    <p>I just started to play with <a href="http://docs.phonegap.com/en/2.4.0/cordova_file_file.md.html#File" rel="nofollow">File API</a> of PhoneGap and already have some problems with saving process. Here is the javascript code:</p> <pre><code>function saveCourseToFile() { console.log("checkpoint 1"); window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, onFSSuccess, onFSError); } function onFSSuccess(fileSystem) { console.log("checkpoint 2"); console.log("Opened file system: " + fileSystem.name); fileSystem.root.getFile("course.oerk", {create:true, exclusive:false}, gotFileEntry, onFSError); } function gotFileEntry(fileEntry) { console.log("checkpoint 3"); fileEntry.createWriter(gotFileWriter, onFSError); } function gotFileWriter(writer) { writer.onwrite = function(evt) { console.log("checkpoint 4: write success!"); }; writer.write("test test test"); } function onFSError(err) { console.log(err.code); } </code></pre> <p><strong>UPDATE:</strong></p> <pre><code>&lt;script type="text/javascript"&gt; function init() { document.addEventListener("deviceready", onDeviceReady, false); } &lt;/script&gt; &lt;body onload="init()"&gt; &lt;div id="page1"&gt; &lt;a href="#page2"&gt;Click me&lt;/a&gt; &lt;/div&gt; &lt;div id="page2"&gt; &lt;script type="text/javascript"&gt; saveCourseToFile(); &lt;/script&gt; &lt;p&gt;Text text text text&lt;/p&gt; &lt;/div&gt; &lt;/body&gt; </code></pre> <p>But in the device file system no such file (course.oerk) as a result. Here is a piece of logcat:</p> <pre><code>02-18 22:36:55.542: D/Cordova(746): onPageFinished(file:///android_asset/www/index.html#coursesPage) 02-18 22:36:55.542: D/Cordova(746): Trying to fire onNativeReady 02-18 22:36:55.552: D/DroidGap(746): onMessage(onNativeReady,null) 02-18 22:36:55.552: D/DroidGap(746): onMessage(onPageFinished,file:///android_asset/www/index.html#coursesPage) 02-18 22:36:56.223: I/Choreographer(746): Skipped 36 frames! The application may be doing too much work on its main thread. </code></pre> <p>Any help would be appreciated.</p>

    2. CO@SimonMacDonald my onDeviceReady includes in `<body>` tag and I'm trying to call `saveCourseToFile()` after moving to the particular `<div>` tag. See code **update** for details.

    3. COOkay, but what is your error? There is nothing in logcat to show that saveCourseToFile was even called.

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.

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