Question

I need to stock some datas in my application.
I know that i can do it like this:

class:

public class MyApplication extends Application {

    private String someVariable;

    public String getSomeVariable() {
        return someVariable;
    }

    public void setSomeVariable(String someVariable) {
        this.someVariable = someVariable;
    }
}

Implementation:

MyApp appState = ((MyApp)getApplicationContext());
String state = appState.getSomeVariable();

This is working if i’m in an activity.

But if i’m in a class not extended from Activity, how can I access at my datas?

thanks in advance for your help!

Answer 1

Perhaps by injecting all the required for a class data via constructor or special setter, I would suggest former one. (Constructor Injection vs. Setter Injection)

There are more solutions like static fields but personally I do not like this approach since statics sometimes makes unit testing a bit messy.

BTW, what kind of variables you want to share?
