I. Introduction of LeakcanaryLeakcanary is a library of open-source detection memory leaks from square, which can easily integrate with your project and monitor memory leaks in the debug version of activity, fragment, etc.After the leakcanary is integrated into the project, a message is sent to the system notification bar when a

; Nulgrind just shows developers how to create a tool. We will not do the introduction.Three use ValgrindValgrind is very simple to use and you don't even need to recompile your program to use it. Of course, if you want to achieve the best results, get the most accurate information, or need to recompile as required. For example , when using Memcheck, it is best to turn off optimization options. The format of the Valgrind command is as follows:Valgrind [valgrind-options] Your-prog [Your-prog opti

1 Background:The x86 platform has comprehensive user-mode memory detection tools such as valgrind. It can monitor detailed memory information during the running of the program to precisely locate memory problems. However, with the rapid emergence of new platforms, such as th
. the only exception is stdafx. H (or any other precompiled header ). a precompiled header, such as stdafx. h, must always be the first header encoded in a source file, so VLD. h must be encoded ded after any precompiled headers.2. if your program contains one or more DLLs that you wowould also like to check for memory leaks, then also include VLD. h in at least one source file from each DLL to be removed ded in l

H and so on, you can also put the pre-compiled header file stdafx. h, and introduce the pre-compiled header file in the source file, the VLD. h can be introduced in multiple source files or common header files, for example, in. H and B. VLD is introduced in H. h. Multiple source files introduce. H and B. h, there is only one VLD in the process.
