Cannot resolve method .runOnUiThread

I have the same problem, and I replaced runOnUiThread() with getActivity().runOnUiThread(). And it worked.

You can move service handler as private member class inside your activity like below to use Activity's this context.

class MyActivity extends Activity {

    private class ServiceHandler /** Whichever class you extend */ {
        public void run() {
            MyActivity.this.runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    mAdapter.notifyDataSetChanged();
                }

            });
        }
    }

    private MyListAdapterTracks mAdapter;

    private ServiceHandler mHandler;

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

        // Some code

        mAdapter = new MyListAdapterTracks(getActivity(), R.layout.item_layout, list);
        listView.setAdapter(mAdapter);

        // Some code

        ServiceHandler sh = new ServiceHandler();
        sh.run();
    }
}

EDIT:

public class ServiceHandler /** Whichever class you extend */ {

    private final Activity mActivity;

    private final MyListAdapterTracks mAdapter;

    public ServiceHandler(Activity activity, MyListAdapterTracks adapter) {
        mActivity = activity;
        mAdapter = adapter;
    }

    @Override
    public void run() {
        mActivity.runOnUiThread(new Runnable() {

            @Override
            public void run() {
                mAdapter.notifyDataSetChanged();
            }

        });
    }

    // More code

}

And then instanciate it in your activity like this:

class MyActivity extends Activity {

    private MyListAdapterTracks mAdapter;

    private ServiceHandler mHandler;

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

        // Some code

        ServiceHandler sh = new ServiceHandler(this);
        sh.run();
    }
}
