Why is my c# paint method running out of memory?

阅读更多关于 Why is my c# paint method running out of memory?

问题 I'm new to c#, and trying to learn by writing some simple apps to get familiar with the syntax and .NET library. The most recent miniproject I took on is a polar clock like the one found here. One of the problems I noticed early on was that the app would constantly "flicker", which really took away from the presentation, so I read online about how to implement a double buffer, which eliminated this problem, but may or may not have something to do with the problem. Here is my onPaint method;

Out of memory exception reading and writing text file

阅读更多关于 Out of memory exception reading and writing text file

问题 I get an out of memory exception a few seconds after I execute the following code. It doesn't write anything before the exception is thrown. The text file is about half a gigabyte in size. The text file I'm writing too will end up being about 3/4 of a gigabyte. Are there any tricks to navigate around this exception? I assume it's because the text file is too large. public static void ToCSV(string fileWRITE, string fileREAD) { StreamWriter commas = new StreamWriter(fileWRITE); var readfile =

问题 We're getting an OutOfMemory error inside the Volley library while parsing the network response. This occurs with a large responses on crappy phones. Can this be avoided?

Spark clean up shuffle spilled to disk

阅读更多关于 Spark clean up shuffle spilled to disk

问题 I have a looping operation which generates some RDDs, does repartition, then a aggregatebykey operation. After the loop runs onces, it computes a final RDD, which is cached and checkpointed, and also used as the initial RDD for the next loop. These RDDs are quite large and generate lots of intermediate shuffle blocks before arriving a the final RDD for every iteration. I am compressing my shuffles and allowing shuffles to spill to disk. I notice on my worker machines that my working directory

ImageAdapter and ListView (java.lang.OutOfMemoryError: bitmap size exceeds VM budget)

阅读更多关于 ImageAdapter and ListView (java.lang.OutOfMemoryError: bitmap size exceeds VM budget)

I'm using ListView to display images which I provide through an ImageAdapter class. it works great on my device (and on many other devices which I tested it on), but somehow when I'm using the emulator and I'm long-pressing the up/down button - I'm getting an outOfMemory error after 10-15 seconds. I tried clearing cache, canceling cache, etc. - nothing helped. I know this crash is pretty rare (i couldn't reproduced it on any "real" device), but I can see on DDMS that "GC freed" are getting bigger during that long press and I can't find a way to clear them. Any help will be appreciated, Tnx.

问题 I am building an app that buffers N camera frames and when the user taps a button it saves the photo using all the saved frames applying an effect. I am saving the photo and processing the frames on an AsyncTask . When I execute it, I remove everything from the screen and leave only a TextView to display the progress of saving the photo. Currently the AsyncTask doInBackground looks like this: protected Void doInBackground(Integer... params) { int w = mBuffer.get(0).getWidth(); int h = mBuffer

Anybody know reason why this
