Introdution

Let's look at the example. This is Activity made in standard way:

public class MainActivity extends BaseActivity {

    @UiThread
    public static void start(Context context, String name, int id, char grade, boolean isPassing) {
        Intent intent = new Intent(context, StudentDataActivity.class);
        intent.putExtra("nameArg", name);
        intent.putExtra("idArg", id);
        intent.putExtra("gradeArg", grade);
        intent.putExtra("isPassingArg", isPassing);
        context.startActivity(intent);
    }

    String name;
    int id;
    char grade;
    boolean isPassing;

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

        Intent intent = getIntent();
        name = intent.getStringExtra("nameArg");
        id = intent.getIntExtra("idArg", -1);
        grade = intent.getCharExtra("gradeArg", 'a');
        isPassing = intent.getBooleanExtra("isPassingArg", false);
    }
}

And we start it by:

MainActivity.start(context, name, id, grade, isPassing);

With ActivityStarter all you need is:

public class MainActivity extends BaseActivity {

    @Arg String name;
    @Arg int id;
    @Arg char grade;
    @Arg boolean isPassing;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ActivityStarter.start(this); // This can be located in BaseActivity, one for all activities

        //...
    }
}

And you start it nearly the same way:

MainActivityStarter.start(context, name, id, grade, isPassing);

Simillar way you can take Intent or start activity with flags:

MainActivityStarter.getIntent(context, name, id, grade, isPassing);
MainActivityStarter.startWithFlags(context, name, id, grade, isPassing, FLAG_ACTIVITY_SINGLE_TOP);

This are only simple examples of SuperActivity usage. It is helping to make code concise and more readable. Library is providing also lot's of other possibilities.
