Now if the orientation changes the Drawable will not come under GC because it is static and due to this the ImageView will also not go under GC operation because the Drawable is linked to the ImageView by the Drawable callback and same for Activity context because ImageView was created with Activity context.
#UBUNTU ANDROID STUDIO RUNNING OUT OF MEMORY CODE#
In the code snippet above, this means the drawable has a reference to the ImageView which itself has a reference to the activity (the Context) which in turns has references to pretty much anything (depending on your code.). When a Drawable is attached to a view, the view is set as a callback on the drawable. This code is very fast and also very wrong it leaks the first activity created upon the first screen orientation change. We make an Activity and create a TextView with Activity context and set a sample text in to it. First lets see a memory leak examples: Examples:ġ. The biggest reason for Out of memory is a Memory leak. You have to deal very carefully with large bitmaps by loading the size that you need not the whole bitmap at once and then do scaling. You are dealing with large bitmaps and loading all of them at run time. You are leaking some memory i.e you didn’t make the previous objects you allocated eligible for Garbage Collection (GC). You are doing some operation that continuously demands a lot of memory and at some point it goes beyond the max heap memory limit of a process.Ģ. There are number of reasons why we get a Out of memory errors. When some process demands a higher memory than its limit it causes a error i.e Out of memory error. There is a limit on the memory a process can demand and it is different for different devices and also differs for phones and tablets. Each Linux Process has a Virtual Machine (Dalvik Virtual Machine) running inside it. In Android, every application runs in a Linux Process. OOM error comes when the allocation crosses the heap limit or your process demand a amount of memory that crosses the heap limit. In this case we have to be very careful and efficient while handling the images or object allocation and deallocation. Out of memory error is very common error when you are developing for a application that deals with multiple images sets or large bitmaps or some Animation stuff. Then run update-initramfs -u to ensure that the installed initrd stays small and Grub will be able to boot.Varun Bhardwaj 26 Aug 13 Out of Memory (OOM) Error Check first using ls (hd0,gpt4)/ in the Grub console)Īfter installation you should mount the installed system, enter a chroot, and set MODULES=dep in /etc/initramfs-tools/nf. Change the line initrd /casper/initrd to initrd (hd0,gpt4)/initrd.1.new (partition identifier may differ on your system.In Grub select the first option and press 'e' to edit the menu entry.Create a 4th partition on your USB drive using fdisk and format it as ext4.Copy the original initramfs and write initrd.3.new to the original offset (in my case 62 + 9004 = 9066): cp initrd.1 & dd if=initrd.3.new of=initrd.1.new seek=9066.Unpack the first layer: mkdir unpack.1 & cpio -D unpack.1 -idv.Copy /casper/initrd from the USB medium to a working Ubuntu machine and call it initrd.1.To reduce the size one of the things you can do is the following: In my case at least the initrd was too big for grub to handle.
