The problem you found is that

Inner classes in Java capture ("close over") the lexical scope in which they are defined. But they only capture variables that are declared "final".

If this is clear as mud, there's a good discussion of the details here: Cannot refer to a non-final variable inside an inner class defined in a different method

But your solution looks fine. In addition, provided that data is final, you could simplify the code to this:

public void OnNewSensorData(final Data data) {
    runOnUiThread(new Runnable() {
        public void run() {
            // use data here
            data.doSomething();
        }
    });
}
