out-of-memory

I have a large XML file (around 400MB) that I need to ensure is well-formed before I start processing it. First thing I tried was something similar to below, which is great as I can find out if XML is not well formed and which parts of XML are 'bad' $doc = simplexml_load_string($xmlstr); if (!$doc) { $errors = libxml_get_errors(); foreach ($errors as $error) { echo display_xml_error($error); } libxml_clear_errors(); } Also tried... $doc->load( $tempFileName, LIBXML_DTDLOAD|LIBXML_DTDVALID ) I tested this with a file of about 60MB, but anything a lot larger (~400MB) causes something which is

I have an app that loads a lot of big images remotely. When I use nostra's Universal Image Loader ( https://github.com/nostra13/Android-Universal-Image-Loader ) I often get Out Of Memory errors. I don't know how I should set up the imageloader to prevent this. This is my current ImageLoader specs: ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context) .enableLogging() .memoryCache(new WeakMemoryCache()) .build(); this.imgDispOpts = new DisplayImageOptions.Builder() .cacheInMemory() .cacheOnDisc() .imageScaleType(ImageScaleType.IN_SAMPLE_INT) .build(); this.imageLoader

I am pretty new to Android and have been developing a game. Every now and again I have users reporting out of memory exceptions , which I find surprising since the bitmaps that I create are at most 200 kb in size. I call BitmapFactory.decodeResource() whenever I create a new sprite . Since my application is a zombie defense game, you could expect that I create sprites quite often. Every time I create a sprite, I call decode resource to generate a bitmap. My question is if I was to only call decode resource at the start of each activitiy, and refer to the bitmap at package level, would this

I have 9 GB of data, and I want only 10 rows. When I do: data.OrderBy(datum => datum.Column1) .Take(10) .ToArray(); I get an OutOfMemoryException . I would like to use an OrderByAndTake method, optimized for lower memory consumption. It's easy to write, but I guess someone already did. Where can I find it. Edit : It's Linq-to-objects. The data comes from a file. Each row can be discarded if its value for Column1 is smaller than the current list of 10 biggest values. I'm assuming you're doing this in Linq to Objects. You could do something like... var best = data .Aggregate(new List<T>(),
