    <p>I have an android application that parses some HTML, downloads an image, and displays it. I'm using an <code>AsyncTask</code> to do the HTML parsing and image downloading, but that shouldn't be relevant. I never have a problem when I'm on WiFi on my phone, when I'm using the Eclipse debugger on my phone, or when I'm using the emulator. When I have my phone on the cell network (even with pretty good reception), the image sometimes fails to display.</p> <p>I'm having a hard time figuring out what is wrong, since the problem cannot be reproduced in the debugger. Does anyone have any idea what could be wrong?</p> <p>Thanks!</p> <p><strong>Update:</strong> I have narrowed it down to the image downloading function. This way my original code:</p> <pre><code>private Bitmap downloadImage(String url) { Bitmap image = null; debug = ""; try { URL image_url = new URL(url); HttpURLConnection image_connection = (HttpURLConnection) image_url .openConnection(); image_connection.connect(); InputStream image_stream = image_connection.getInputStream(); debug = image_stream.available()+""; image = BitmapFactory.decodeStream(image_stream); } catch (Exception e) { Log.e("downloadImage", "Exception: "+e.getMessage()); } return image; } </code></pre> <p>I have also tried using the code from this tutorial, but the same bug showed up.</p> <p><a href="http://www.devx.com/wireless/Article/39810/1954" rel="nofollow noreferrer">http://www.devx.com/wireless/Article/39810/1954</a></p> <p>At this point I think it must have to do with Verizon, but I'm not sure how to figure out what's going on. I wish there was something like Wireshark for Android. I've given my code to a friend of mine on T-Mobile with the G1 and a friend on Sprint with the EVO. I have the Droid Eris on Verizon.</p>

    1. COAt all does it transfers some data? Mobile connections use some kind of proxys, maybe you should check your server logs to get more info.

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.
