Android will never reach it's full potential if it ties itself to a 
patent system that is is considered as a joke around the world.

Alas US patent laws may be hampering functionality...

 I have MT on my G1 and the truth is that I hardly ever use it. Unlike
iPhone that requires zoom in in order to being able to press on small
links and opens the page all zoomed out, the G1 has a trackball that
is much more superior that finger press for links and is zooming-in
auto to a readable size. Not saying the "pinch to zoom" is not cool or
useful when you do need to zoom, it's just not necessary as it is on
the iphone.

 It seems this really is just a rumor. Luke Hutchison(the guy who
actually implemented the multi-touch hack) has this to say about the
issue:

 http://lukehutch.wordpress.com/2009/02/10/multi-touch-and-more-tinfoil-hats/ 

If you look at his work, he has a good deal of credibility.  Since I
don't plan on going through the whole codebase myself this week, I'll
take his word for it.

 Can Apple's Multi-Touch Patent Withstand Scrutiny -- or Challenge?

Btw, there is a company that is collecting prior art right now to
challenge Apple's patent..........Contact me if you want to know
more ;)

 ncorrect. Multi touch brings huge user interface options, while
taking away none. (You can still single touch on a multi touch
screen. ;P) It will come to Android-- or consumers (anything past low
end) will lose interest compared to other multi touch offerings.

Unless you've had an iphone-- and played with some apps that make good
use of it, you may not get it.

Multi-touch is one feature. For some subset of the device-buying market,
it is a killer feature and devices that lack it will not be considered.
For the rest of the market, they will assign some level of importance to
it and will take it into account when making their decisions.

In other words, *some* "customers...will lose interest", but not
necessarily all.

2. AutoCompleteTextView and Ajax-like request

Hello,

I am trying to implement an AutoCompleteTextView backed by HTTP
requests. i.e., the content of the suggestion comes from a web service
and is obtained by a HTTP request (for example, the symbol lookup
field on Google finance).

Here's the code I wrote to initialize the autocomplete field:

final AutoCompleteTextView field =
(AutoCompleteTextView)findViewById(R.id.lookup_input_field);
List<String> suggestions = new ArrayList<String>();
final MyAutoCompleteAdapter adapter = new MyAutoCompleteAdapter(this,
R.layout.auto_complete_dropdown, suggestions);
field.setAdapter(adapter);
field.addTextChangedListener(new Tex{*filter*}cher() {
        public void afterTextChanged(Editable s) {}

        public void beforeTextChanged(CharSequence s, int start, int count,
int after) {}

        public void onTextChanged(CharSequence s, int start, int before, int
count) {
                String newValue = field.getEditableText().toString();
                adapter.valueChanged(field, newValue);
        }
});

And here's the valueChanged method of the adapter. The suggestion
retrieval is done in a thread to ensure responsive UI.

public void valueChanged(final AutoCompleteTextView view, final String
value) {
        final Handler handler = new Handler() {
                public void handleMessage(Message msg) {
                        clear();
                                List<String> suggestions = 
(List<String>)msg.obj;
                                for (String suggestion : suggestions) {
                                        add(suggestion);
                                }
                                notifyDataSetChanged();
                        }
                };
                new Thread() {
                        public void run() {
                                List<String> suggestions = 
SearchHelper.search(value);
                                if (suggestions.size() > 0) {
                                        Message msg = new Message();
                                        msg.obj = suggestions;
                                        handler.sendMessage(msg);
                                }
                        }
                }.start();
        }

Here's my problems: a) The suggestion dropdown doesn't always show up
on each keystroke, even though I know the SearchHelper has
successfully requested and returned suggestions based on user input.
b) When I select an item, the onTextChanged seems to be invoked again
and the suggestion dropdown shows up again.

Sorry if someone has discussed this issue but I wasn't able to find
any examples for my scenario.

Thanks!

Ken
