. Choosing the right algorithm and data structure is always the first thing that developers should consider. At the same time, we should always remember to write the two basic principles of Efficient Code: (1) do not do unnecessary things; (2) Do not allocate unnecessary memory. I've been working on Android since last year, combining my own little project experience, taking into account Google's optimized

Han Mengfei sha yue31313 Han Yafei Han_meng_fei_sha [email protected]What areas of Android memoryWhat are the areas of memory============memory is divided into 5 large areas1. Stack (stack)-Automatically allocated by the compiler to release, store the function parameter value, local variable value and so on. It operates in a manner similar to a stack in a data st

Many people think that Java programs, because there is a garbage collection mechanism, there should be no memory leaks. In fact, if we no longer use an object in a program, but because there is still a reference to it, the garbage collector cannot reclaim it, and of course the memory used by the object cannot be consumed, which results in a memory leak. If our Ja

1. Android Process Management MemoryAndroid is primarily used in embedded devices, and embedded devices are usually not highly configurable due to some well-known conditions, especially when memory is relatively limited. If we write code that has too much memory usage, it will inevitably make our device run slowly, or even crash. To enable

Generalized mobile phone system memory is divided into "mobile phone running Memory" and "mobile phone non-running memory." The "Running memory" of the phone is the ram of the phone, which is equivalent to the memory of the comput
