Some users report that these images are showing up in their gallery application.

Is there a way to tell the system not to include these images in the gallery? It's just an annoyance to the users.</p>

Everything works great when users (left)click on the link to the script, they are presented with a download dialog with the filename ending in .csv and it suggests using excel, or calc, to open it. However, when users right-click and choose Save As it is being saved with the php script name.</p>
<p>Here is the header code:</p>

header("Expires: 0"); // set expiration time

<li>remove the icon from the system tray</li>
<li>reduce the amount of space Java uses for temporary files</li>

<p>I was able to do 2 and 3 by going to the Java Control Panel (systray icon > properties, or Control Panel > Java), unchecking the box/changing the number, and selecting "Apply" and "OK." However, I cannot do 1.</p>
<p>My steps so far: go to the Update tab, deselect "Check for Updates Automatically," click "Never Check" instead of "Check Monthly" and see the "Advanced" button get grayed out.

805,463 | 805,464 | Android ApiDemos TextAlign not aligning in test program outside of demo program | <p>I cut out the code for the <code>Graphics->Text Align</code> activity from the <code>ApiDemos</code> for Android, and pasted it into a new activity. When I run it on larger higher density screens (both on my physical phone, and on a 480x800 emulator), the text does not scale to fill the screen. </p>
<p>I have put the code in <code>BeyondCompare</code> and cannot find anything significantly different between the 2 activities, yet when run outside of the <code>ApiDemos</code> program, it does not scale properly. When run from the <code>ApiDemos</code> program, it scales fine; I have even made the <code>TextAlign</code> activity the only one that runs from the <code>ApiDemos</code> and it still scales fine.</p>
<p>I checked the manifests of both programs and there does not appear to be anything that would cause the canvas to stop scaling appropriately. The activity creates a <code>SimpleView</code> class when it starts, so it does not appear to be using XML for the layout.</p>

5,391,492 | 5,391,493 | Android animating image pieces and device compatibility | <p>I am creating an application which on one view has an image of an elephant. this elephant needs to animate various parts of his body such as eyes, trunk, spraying water, and also the background/horizon movements. I have briefly tried positioning each element(eye, trunk, etc) in a <code>RelativeLayout</code> using margins and relative positions so that the picture looks correct.</p>
<p>When i change the screen size via eclipse layout editor everything gets out of place. I read that using <code>RelativeLayout</code> with margins and relative positions will be the best alternative to <code>AbsoluteLayout</code>, but i can't seem to get each piece in the right spot while keeping some compatibility of devices.</p>
<p><strong>What is the best way of positioning pieces of the image to complete a full image which will also allow me to animate/translate/rotate/etc each piece and support a large variety of devices?</strong></p>

<p>I have created the iOS version of this application and it was extremely easy to set this up. I don't quite understand how applications line up sprites to make a scene which is compatible among a large variety of screen sizes/densities.</p>
