Access application context in companion object in kotlin

Question

How can we access application context inside companion object in Android kotlin? I have a companion object inside an abstract class and I want to access context to read Shared Preferences, but I'm not able to get the context.

UPDATE: I'm working with this stuff in an Android library and also the class that I'm working in is abstract

Answer 1

Actually I'm working inside an Android library and the class is abstract, so can't go with the already suggested solutions. However, I found way to do that.

1. Creat a lateinit Context field inside companion object.

abstract class MyClass {

    companion object {

        private lateinit var context: Context

        fun setContext(con: Context) {
            context=con
        }
    }
}

2. And then set it after the app has started

public class WelcomeActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_welcome);

        MyClass.Companion.setContext(this);
    }
}
