Android Memory Leak Summary The purpose of memory management is to let us in the development of how to effectively avoid the problem of memory leaks in our application. Memory leaks Everyone is not unfamiliar, it is simply vulgar to say that the released object is not released, has been held by some or some instances

when studying the memory allocations of the JVM, the blog read this blog, which summarizes the memory allocations of the JVM, and also uses the JVM's memory model to explain questions about parameter passing in a Java program.

Reference: http://oldblog.csdn.net/column/details/16384.html In "Fortress besieged" in a sentence, "people outside the wall want to go in, the wall inside people think out", use this to describe between Java and C + + This memory dynamic allocation and garbage collection technology surrounded by the "wall" is more appropriate. For developers engaged in C, C + +, in the area of memory management, they have a

The AVA virtual machine divides the managed memory into several different data regions during Java execution. These zones have their own uses, as well as the creation and destruction of time, and some regions exist as virtual machine processes start, while others are created and destroyed depending on the start and end of the thread.The Java Virtual machine includes the following run-time data regions:Program CounterA program counter is a small area t

Once the memory area is mapped to the address space of the process that shares it, the transfer of inter-process data no longer involves the kernel . However, there is usually some form of synchronization between the processes that store or take information from the shared

One about memory1, memory allocation methodThere are three ways to allocate memory:(1) Allocation from a static storage area. The memory is allocated at the time of program compilation, and the entire running period of the program exists in this block.。 For example, global variables, static variables.(2) Create on the stack. When executing a function, the storage

Notebook selection of large memory, not enough to upgrade, the video is not enough to upgrade. 1G memory is basically enough, if the same graphics card, 2G video memory will be better than 1G video memory, but by the core frequency and the number of stream processors, as well as the impact of the

To understand this knowledge is due to a OutOfMemoryError exception, then the solution is to add the-xmx1024m parameter to expand the Java heap, but also add another parameter-xx:-usegcoverheadlimit.
