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

First we need to know if the program has a memory leak, and then locate which line of code is leaking memory so that it can be repaired. The simplest method of course is the use of professional testing tools, more famous such as Boundscheck, the function is very strong, I believe that people do C + + development can not be separated from it. In addition, you do

then still no recycling, you can find the memory state, get the different object references, get a hprof file, then can find the shortest strong reference path.Resolve a memory leak by using the following methods:Then we need to fix: How to get an object that is not recycled. referencequeue+weakreference+ manually invoking the GC can achieve this requirement.

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 developer

LeakCanary, a memory leak detection tool Simple: we do not create a service, not to make money; we make money to provide better services. We think this is the attitude towards doing things. Everyone who learns to use Java should know that the garbage collection mechanism provided by Java JVM is extremely useful. However, we also know that the garbage collec

Visual Leakdetector (VLD) is a free memory leak detection Tool for Visual C + +. It is characterized by: (1), it is free open source, using the LGPL protocol, (2), it can get the memory leak point of the call stack, you can get the file and line number, (3), it can get the f

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.
