From the GC logs, it appears that the heap size is being reduced across young and old generations after sometime. Below are three entries from the logs. {Heap before gc invocations=5: PSYoungGen total 44800K, used 44180K [0x18220000, 0x1b420000, 0x24a20000) eden space 38400K, 100% used [0x18220000,0x1a7a0000,0x1a7a0000) from space 6400K, 90% used [0x1ade0000,0x1b3853c8,0x1b420000) to space 6400K, 0% used [0x1a7a0000,0x1a7a0000,0x1ade0000) PSOldGen total 51200K,

Android: OutOfMemory error and the backstack
the following sheet represents the working flow in the application this question is about. I ran into problems with OutOfMemory Errors, mostly because users were able to switch from activity B to activity D multiple times (They are showing different content for every attempt), without the previous activity being destroyed.

Java Virtual Machine Heap Tuning Parameters
What would be the effect of setting only -Xms without setting a -Xmx for eg. java -Xms 2048m ? Does setting a high lower value for -Xms mean lesser Heap Fragmentation? Answer Setting -Xms to the estimated heap requirement of your application will speed up start of your application (of course Xms must be <= Xmx). Reason is the VM
JVM error when try to allocate more than 128M Xms, without specifying Xmx
I am seeing an JVM issue when I am running my application and I simply to below java commands: Even Xms is set to 128M does not work: Works only when Xms is set to 64M or less: The interesting thing is if I specify Xmx, then it works well. More interesting thing is: All above commands run well on

Java collections faster than c++ containers?
I was reading the comments on this answer and I saw this quote. Object instantiation and object-oriented features are blazing fast to use (faster than C++ in many cases) because they’re designed in from the beginning. and Collections are fast. Standard Java beats standard C/C++ in this area, even for most optimized C code. One user (with really high rep
Is it possible to install 64 bit JVM on linux so heap can be larger then 2gb?
It’s a 32 bit Ubuntu OS I want to be able to run with more than 2g of heap Answer No. A 32-bit kernel(and likely 32-bit CPU as well) cannot run a 64-bit executable for the JVM(or any other 64-bit executable/ELF) with your choice of OS and kernel.
