2,745,866 | 2,745,867 | app crashes while writing data together | <p>I am trying to write NSData objects together. It's a 450 mb file. I'm doing it with 50mb chunks like so:</p>
<pre><code>for (NSString *packetName in listOfFiles) {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSString *packetPath = [[self applicationDocumentsDirectory] stringByAppendingPathComponent:packetName];
NSData *packetData = [[NSData alloc] initWithContentsOfFile:packetPath];
[output seekToEndOfFile];
[output writeData:packetData];
[fileManager removeItemAtPath:packetPath error:&error];
NSLog(@"Removed file after appending data success: %i Error: %@", success, [error localizedDescription]);
[self updateManifestColumn:@"IsParsed" withValue:YES forFile:packetName inTable:tableName];
packetData = nil;
[packetData release];
[pool release];
}
[output closeFile];
</code></pre>
<p>I call this method, right after I received the packets in connectionDidFinishLoading. I saved those files to the Documents directory so the user could download first on Wifi, and then the restitching could happen afterwards. This is done in a DataManager class which handles these types of operations so I don't have didReceiveMemoryWarning like I would in a ViewController. I do not get a Memory warning on the Console when I run the app on the device connected to my machine. </p>
<p>What should I do if it's in the middle of writing the data to ensure that the data is correct when the user receives it? Would it be better to do this with smaller packets? Does that make it safer? Thanks!</p>

However, when I set the color using hex values or using the setARGB method, it doesn't work. But when I use Color.x (eg, Color.GREEN) it works. Here's the code:</p>
<pre><code> Bitmap image = Bitmap.createBitmap(bitmapWidth, bitmapHeight, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(image);
Paint paintBackground = new Paint();
int green = Color.argb(0, 0, 255, 0); // 65280 (Won't work)
green = 0x0000ff00; // 65280 (Won't work)
paintBackground.setARGB(0, 0, 255, 0);
green = paintBackground.getColor(); // 65280 (Won't work)
green = Color.GREEN; // -16711936 (Works!)
paintBackground.setColor(green);
green = paintBackground.getColor(); // -16711936
paintBackground.setStyle(Paint.Style.FILL);
canvas.drawRect(0, 0, bitmapWidth, bitmapHeight, paintBackground);
</code></pre>
<p>So basically Color.GREEN returns -16711936 - and this WORKS.
However, the hex value is 65280 - and this DOES NOT WORK. That is, it doesn't paint the green rectangle.</p>
<p>I need to use hex values because I need to set the color to <code>0x00ffff00</code> here and then later to a different hex value.</p>

1,084,043 | 1,084,044 | New Android Developer Console: Update Apk and Store Listing before Publish | <p>I tried uploading an update for the first time using the NEW DEVELOPER CONSOLE.

I seem to be able to upload APK and publish, or update the store listing and publish, but not BOTH before publishing. This seems very strange to me.</p>
<p>This is what I tried:</p>
<ol>
<li><p>I uploaded my apk using the "Simple Mode", but was then prompted to "Publish Now" before getting a chance to change the store listing (e.g. recent changes). Why?</p></li>
<li><p>I changed to "Advanced Mode" and was able to upload my apk and save as a draft. I then tried to access the Store Listing, but this said that I could not save changes since I had archived or reactivated one or more apks.</p></li>
<li><p>I changed tactics. I started with going to Store Listing and modified my recent changes. Then I tried going to the APK area to upload my new version and it says that it can't save the Store Listing without publishing... what the heck???</p></li>
</ol>
<p>This is just retarded, or am I misunderstanding the whole concept of "publishing"?</p>

2,797,412 | 2,797,413 | Wordpress > getting full path to my theme's images directory regardless of parent paths | <p>I have a function whose purpose is to list the folders within the images directory of my wordpress theme. It works great when the user has installed wordpress in the root directory of the site. However, it fails if the user has installed wordpress in a folder under the root...</p>
<p>$mydir = get_dirs($_SERVER['DOCUMENT_ROOT'].'/wp-content/themes/mytheme/images');</p>
<p>This function works fine as long as the wordpress is installed directly into the site's root, such as site.com/index.php</p>
<p>However, this path method fails, if the user has installed their blog in a virtual directory. Example: site.com/somedirectory/index.php</p>
<p>Can someone help with a better method of determining the path of the $mydir?</p>
<p>It would be super simple if I could feed my function with the http address, but my function requires the path to the images directory as a server directory. Anyone know of a way to find the folders under a given directory using the http method instead? For example, I can get a reference to my theme's images directory with...</p>
<p>$mydir = get_bloginfo('url').'/wp-content/themes/mytheme/images';</p>
<p>However, the function below, will not take a URL, it must be a physical file path to the chosen directory I want to parse. So I either need to replace it with a function that takes a URL or I need to find some way to convert the $mydir function to a physical path, or perhaps some other means.</p>
<p>Here is the function that I'm using for parsing the directory and assigning each folder to an array.</p>
<pre><code>function get_dirs($path = '.')
{
$dirs = array();
try
{
foreach (new DirectoryIterator($path) as $file)
{
if ($file->isDir() && !$file->isDot())
{
$dirs[] = $file->getFilename();
}
}
}
catch(Exception $e)
{
//log exception or process silently
//just for test
echo "There is a problem inside the get_dirs function";
}
return $dirs;
