    <p>I have been working on an app that collects a csv file from dropbox and then display's it. Since I am using phonegap I have been developing and testing with a browser, Firefox to more precise. At the end of the day I loaded it on to my HTC tablet with android 3.2.1 and it just didn't work. Here's the code currently used:</p> <pre><code>$.get('https://dl.dropboxusercontent.com/u/53792213/App/David.csv', function(data) { alert('Success'); // Do stuff }) .fail(function() { alert('error'); }); </code></pre> <p>This code works absolutely fine in Firefox and on an android emulator with android 4.2.2. But not on the real physical device.</p> <p>I simply cannot work it out. No errors are given, and the fail function is never called. Both alert's I have added don't fire. </p> <p>It is extremely frustrating as I don't have access to remote debugging, and I can't debug on the desktop as it works fine on the desktop.</p> <p>I am using jquery 2.0.2 along with jquery mobile 1.3.1</p> <p>I'd appreciate even the slightest clue as to what is going on.</p> <p>EDIT: In order to find out about the error, now that it is infact throwing an error I modified my statement to this:</p> <pre><code>$.get('https://dl.dropboxusercontent.com/u/53792213/App/David.csv', function(data) { alert('Success'); // Do stuff }) .fail(function(jqXHR, textStatus, errorThrown) { alert("An AJAX error occured: " + textStatus + "\nError: " + errorThrown); }); </code></pre> <p>However this is the error it returns: </p> <pre><code>An AJAX error occured: error Error: </code></pre> <p>A blank error message? Either I'm doing something wrong or javascript wants to kill me slowly.</p> <p>EDIT 2:</p> <p>After doing some experiments I have discovered more strange behaviour. If I add the get() function directly into my deviceReady function, as in it will get fired when the app is loaded and ready to go, it works perfectly.</p> <p>But (and this is what has been happening) if I bind a click jquery event in the device ready function, and then call the get function inside it, it doesnt work. Here have a look at this:</p> <pre><code>var App = { // Application Constructor initialize: function() { this.bindEvents(); }, bindEvents: function() { document.addEventListener('deviceready', this.onDeviceReady, false); }, onDeviceReady: function() { //This does work $.get('http://dl.dropboxusercontent.com/u/53792213/App/DavidColson.csv', function(data) { alert('Success'); }) .fail(function(jqXHR, textStatus, errorThrown) { alert("An AJAX error occured: " + textStatus + "\nError: " + errorThrown); }); $("#Button").bind("click", function(event) { alert("Hello"); //This does not work $.get('http://dl.dropboxusercontent.com/u/53792213/App/DavidColson.csv', function(data) { alert('Success'); }) .fail(function(jqXHR, textStatus, errorThrown) { alert("An AJAX error occured: " + textStatus + "\nError: " + errorThrown); }); }); }, </code></pre> <p>};</p> <p>In the above situation the hello alert fires, but not the success alert, instead I get a blank ajax error. Any ideas?</p>

    2. COAlso, since you're requesting an asset using https, if your page wasn't served from the same server using https (the dropbox domain) then a potential source of the error is you violating the same origin policy in your browser.

    3. COHow do I fix that? It's not actually a browser as such but a web view on android. I hoping there is a way to fix that. Or some alternative way of transfering files to the app

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).
