Is passing Context as a parameter to a method in a Singleton class causes memory leak

问题

I'm declaring a Singleton class where I need to pass context parameter for one of the methods in this class

public class MySingleton() {
    Private Context mContext;
    Private static MySingleton mInstance;

    public static MySingleton mInstance() {
        if (mInstance == null) {
            mInstance = new MySingleton();
        }
        return mInstance;
    }

    public void myMethod(Context context)
    {   
       this.mContext = context;
       // write your code here....
     }
}

will this cause a memory leak.

回答1:

It could, as you do not know what sort of Context you will be referencing. It would be safer to write:

this.mContext = context.getApplicationContext();

This way, you are certain that mContext is referencing the Application singleton.
