Question

I have created a class which holds global vars:

public class GlobalVar extends Application{

    private XData xData;

    public XData getxData ()     
    {         
        return xData;     
    }     

    public void setXdata  (XData Xdata)     
    {
        this.xData = xData;                
    } 
}

When I access this class using (GlobalVar)getApplicationContext() from the activities of my application its fine, but when I want to access it from another class (in this case its LocationListener), I cant use (GlobalVar)getApplicationContext()

How could I access the data?

Answer 1

You should implement the Singleton pattern on your GlobalVar class. And access them directly without getter/setter is recommended on android (read the performance guide).

You could also just make your xData variable static and than you can access it directly from everywhere.
