ace leak detection

Since Google released Android studio in 2013, Android studio has been replacing eclipse with its own good memory optimizations, cool UI themes, powerful auto-completion hints, and Gradle compiler support. Become the mainstream Android development IDE. Android Studio provides us with a good coding experience, as well as many tools for app performance analysis, making it easier for developers to analyze app performance. Google has been telling developers in the IO conference not to use cell phone

1. Static analysisWith static analysis, we can get the most initial insight into some of the code's non-canonical places or memory leaks, which is our first step in detecting memory leaks. Of course, there are some warnings that we don't care about to skip.2. Check for memory leaks with instrumentsThis method can roughly locate where we have a memory leak. The method is to complete a loop operation, if the memory growth of 0 proves that our program do

matched. Trace the declaration period of each piece of memory, for example: Whenever a piece of memory is requested, the pointer to it is added to the list, when released, then the corresponding pointer is removed from the list, to the end of the program to check the list to know that there is no memory leaks. The Visual Studio debugger and the C runtime (CRT) under the window platform use this principle to detect memory leaks.When used in VS, you need to add#define _crtdbg_map_alloc#include Th
