(LIBGDX) how to clean the RAM memory that my app uses?

I have create a game app in libgdx and usually it works well, but sometimes it goes in slow motion, in my opinion is a RAM memory problem. I've a Main class that extends Game.class, in main class i create a play screen class, when the player died i create again the play screen class. I believe that the RAM memory that the memory has not released and after many death it accumulates, in fact if I run the application with the task manager open when the death increase memory also increases.

This is the code:

public class MyGdxGame extends Game(){
    private PlayScreen play_screen;  
    private SpriteBatch batch;
    public void create(){
    batch=new SpriteBatch();

    play_screen=new PlayScreen(this);

    setScreen(play_screen);

}

public void render(){

    if(play_screen.death==true){

        play_screen=new PlayScreen(this);

        setScreen(play_screen);

    }

}

So I did a test:

public void render(){

    do{
        play_screen=null;
        play_screen=new PlayScreen(this);
        setScreen(play_screen);
    }while(1!=2);
}

I ran the app with the task manager open, memory increases rapidly until it crashes. So how i can clean up the RAM memory?

Many LibGDX objects has to be manually cleared for memory, see this. They implement the interface Disposable which has the method #dispose().

I don't see you disposing any of your used resources, your SpriteBatch is one of these objects. When you're done with it call batch.dispose(). Setting it to null afterwards is optional, but recommended because using a disposed resource might lead to unintended behavior. The code will look something like this, which should be called when you no longer need it:

if(batch != null) {
    batch.dispose();
    batch = null;
}

LibGDX memory leaks is almost ever because one or more resources was not disposed
