What does out ofmemoryerror mean in java.lang?
It may not be sufficient, and most likely the application will start to experience java.lang.OutOfMemoryError: unable to create new native thread. To mitigate this problem, you can consider reducing the Heap Size from 5GB to 4GB (if your application can accommodate it without running into other memory bottlenecks).
Is it bad to catch an oom in Java?
In general, it is a bad idea to try to catch and recover from an OOM. An OOME could also have been thrown on other threads, including threads that your application doesn’t even know about. Any such threads will now be dead, and anything that was waiting on a notify could be stuck for ever. In short, your app could be terminally broken.
How to limit the memory size of a Java thread?
However, you can use the java system property –Xss to set the thread’s memory size. Using this property you can throttle down the memory size. Example if you configure -Xss256k, your threads will only consume 125mb of space (i.e. 500 threads X 256k).
How to remove out of memory error in Java?
Solution 1: The easiest solution to remove such error is to increase the memory size of the JVM heap space. To increase the size of the heap space, use “-Xmx” java options to solve the out-of-memory error. This configuration will provide 1024 heap space to the application.
How to update a view in the viewpager?
So when you want to change the data or invalidate the view that you need, you can call the findViewWithTag () method on the ViewPager to retrieve the previously instantiated view and modify/use it as you want without having to delete/create a new view each time you want to update some value.
It may not be sufficient, and most likely the application will start to experience java.lang.OutOfMemoryError: unable to create new native thread. To mitigate this problem, you can consider reducing the Heap Size from 5GB to 4GB (if your application can accommodate it without running into other memory bottlenecks).
Why is the pageradapter not updating the view?
I think that ViewPager, after a notifyDataSetChanged () call takes it’s child views and checks their position with the getItemPosition (). If for a child view this method returns POSITION_NONE, the ViewPager understands that the view has been deleted, calling the destroyItem (), and removing this view.
How to override getitemposition in the pageradapter?
Override getItemPosition in your PagerAdapter like this: public int getItemPosition (Object object) { return POSITION_NONE; } This way, when you call notifyDataSetChanged (), the view pager will remove all views and reload them all.
Why does the JVM throw an out of memory OOM?
At this point, the JVM will throw an OOM (OutOfMemoryError). A memory leak can be very latent. For instance, the application might behave flawlessly during development and QA. However, it suddenly throws a OOM after several days in production at customer site. To solve that issue, you first need to find the root cause of it.
When does a Java application run out of memory?
A memory leak happens when the application creates more and more objects and never releases them. The garbage collector cannot collect those objects and the application will eventually run out of memory. At this point, the JVM will throw an OOM (OutOfMemoryError).
Why is there an out of memory error?
This type of OutOfMemoryError is generated when an application isn’t able to create new threads. This error can surface because of following two reasons: There is no room in the memory to accommodate new threads. The number of threads exceeds the Operating System limit.
