Performance issues when running Android Studio Profiler: The IDE is running low on memory

由 笑着哭i 提交于 2020-12-13 04:05:13
问题 When running Android Studio Profiler I get this message at the bottom after generating two or three "heap dumps": The IDE is running low on memory and this might affect performance. Please consider increasing available heap. My PC runs really slow after getting this message even after stopping the profiler and the only option to restore performance is restarting Android Studio. Why is this happening? Is there any other way to restore the performance after generating a heap dump on a project?

Viewpager loose fragment connection on low memory kill

问题 in my activity i use viewpager. I create two fragments and attach the to the view pager and time to time calling some methods from this fragments in my activity.. afer the app is killed on low memory and recreated fragments are there but no connection with the viewpager somehome.. i can not call MyFragment.mymethod().. it says MyFragment is null public class SectionsPagerAdapter extends FragmentPagerAdapter { public SectionsPagerAdapter(FragmentManager fm) { super(fm); } @Override public

Application.onLowMemory() not invloked

问题 I've create an Application class of my own. I try to debug it and the code stops at Application.onCreate() but does not stop at onLowMemory. To test the scenario I open a lot of other high memory applications. What I see is that the debug session terminated (in eclipse) and some of my static variables turned to null - indicates the the process has ended. Not only did the debug NOT stop @ the breakpoint of the method, I've put a Log.e(...) line and don't see it as well. Any idea of why the

How to cause onLowMemory on device for tests

问题 I want to test our app for low memory cases. Do you have any ideas, how to cause onLowMemory on devices? Thank you. 回答1: I just know only one way to do, which is to create a method running in a different thread that does memory leak, make it loop continuously until onLowMemory() is called, then stop the thread. It's nice if anyone shares experiences on this case! 来源： https://stackoverflow.com/questions/7673516/how-to-cause-onlowmemory-on-device-for-tests

What's an efficient implementation of Conway's Game of Life for low memory uses?

由 我是研究僧i 提交于 2019-12-03 06:02:30
问题 I'm looking for a fast and memory efficient approach for implementing Conway's Game of Life. Constraints: a 96x128 board, approximately 2kB RAM available and 52MHz processor (see the tech specs here: http://www.getinpulse.com/features). My current naive solution that represents each cell as a single bit in a matrix (96*128/8=1,536 bytes) works but is too slow. What tricks can be used to improve performance? Storing the coordinates of live cells (for example in this implementation http://dotat

Memory-mapped files and low-memory scenarios

由 ↘锁芯ラ 提交于 2019-11-28 04:39:56
How does the iOS platform handle memory-mapped files during low-memory scenarios? By low-memory scenarios, I mean when the OS sends the UIApplicationDidReceiveMemoryWarningNotification notification to all observers in the application. Our files are mapped into memory using +[NSData dataWithContentsOfMappedFile:] , the documentation for which states: A mapped file uses virtual memory techniques to avoid copying pages of the file into memory until they are actually needed. Does this mean that the OS will also unmap the pages when they're no longer in use? Is it possible to mark pages as being no
