I want to execute some native code in Android’s main Activity onStart() method.

What’s the best way to set this up in Fuse?

Thanks!

As an addition to this, I really want to add a member to the Activity. For example, as in the following pseudo code.

```auto
class MainActivity extends Activity {
    MyObj myObj;
    public void onStart() {
        myObj = new MyObj();
    }
    public void doSomething() {
        myObj.doSomething();
    }
}

```

Can I do this somehow?

Thanks again!

It might be worth looking at how things are done [in Billing](https://github.com/fusetools/Fuse.Billing.Android/blob/master/src/Fuse.Billing.Android/BillingHelper.uno#L35).

If that doesn’t help, please describe _exactly_ what you want to do, with particular details. Pseudo-code and generic questions can only get us that far.

Hi Iain, good question. Are you interesting in getting this info from JS or Uno?

Thanks guys. I had a think about this and I think I actually need to do it in a different way (from JS/foreign code).

Thanks for your time anyway.
