I would definitely go with OpenGL. I've not used the canvas, but I
seriously doubt it is as fast, and definitely isn't as flexible. It
may be easier to use though if your game is simple (e.g. I would use
it for something like a board game).

Also, using OpenGL will let you easily port your game to other OSes
(except WP7).

It really depends on what you're doing.There are certain things that are
simply not possible or simply slower with OpenGL (e.g. high-quality
anti-aliased vector rendering being one of them). Also not all GLES
driver/chips are the same, and your performance may vary.

 Topic: Launching an application from a email. Is that 
possible?

sdphil  Jan 08 07:12AM -0800 ^

okay, i finally got this to work, but it will only work if i use a
unique scheme. if I try to do it without a standard http scheme, then
i can't get it to work -- even if I specify mimeType.




 Topic: DNS WHOIS query 
support

http://www.dnsjava.org/ might help.

Though, how it works on Android I don't know

Record [] records = new Lookup("android.com", Type.NS).run();
for (int i = 0; i < records.length; i++) {
MXRecord mx = (MXRecord) records[i];
System.out.println("Host " + mx.getTarget() + " has preference ",
mx.getPriority());
}





 Topic: First attempt at LVL 
Licensing

Neilz  Jan 08 06:40AM -0800 ^

Hi all. I'm implementing this into my app and reading through the
docs.

As I understand it I should be able to add a test email address (the
one set up in my device) and it should return whatever response I set.
However, all I'm getting back is Application error: NOT_MARKET_MANAGED

Do I have to upload my app to the market for this to work? Currently
it isn't, but the docs seem to tell my that this isn't necessary for
test accounts.

Thanks.



 Topic: About 
viewstubs

Pedro Duque  Jan 08 02:34PM ^

I'm trying to gasp viewstubs but I feel I'm missing something.

As I understand, a viewstub only exists in a hierarchy until inflated
or until made visible. After that is replaced by its referenced
layout. This behaviour makes impossible to reinflate a inflated
viewstub. Is this correct?

The behaviour I was looking for was to have several buttons that would
open diferente viewstubs. When I click a button it would deflate the
previous layout and inflate the new one but this only works the first
time... After that the viewstub is gone...



 Topic: How to stop ADB 
server

Kumar Bibek  Jan 08 06:20AM -0800 ^

What do you mean by dynamically? From inside an app? What would you
try to do that?

Anyway, to shut down the adb server, you just have to use this
commands

adb kill-server
adb start-server

These are command line tools available for you to interact with adb.




 Topic: What type of messaging would you 
use?

Kumar Bibek  Jan 08 06:17AM -0800 ^

Well, for reliable working, I think it would be best to use multiple
channels. SMS, cloud and local netwo

I don't know whether this is the right forum for this thread. I am
interested to know how to debug those services in system server, is
there some known good approaches? Thanks.
