Today, the editor will share with you the relevant knowledge about how to solve the java memory leak. The content is detailed and the logic is clear. I believe most people still know too much about this, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

1. Memory leakage caused by a single case. Because the static nature of the singleton makes its life cycle as long as the application life cycle, if an object no longer needs to be used, if the singleton object has a reference to the object, the object cannot be recycled normally and the memory is leaked.

The solution is that the life cycle of the singleton is as long as the application, preventing memory leaks.

/ / singleton pattern public class AppManager {private static AppManager instance; private Context context; private AppManager (Context context) {this.context = context;} public static AppManager getInstance (Context context) {if (instance! = null) {instance = new AppManager (context);} return instance;}}

2. Memory leak when the container is in use. Memory leak refers to the execution of the following code that has nothing to do with vector after the completion of the vector operation. If the GC operation occurs, this series of object cannot be recycled, and the memory leak here may be short-lived, because those objects can still be recycled after the entire method () method is executed.

The solution is simple: manually assign the value to null:

Void method () {Vector vector = new Vector (); for (int I = 1; I
