Hi Mark

howdy, David!

how can I help you today?

Is it possible to make GPS background app?

if you mean "is it possible for a service to receive location updates from GPS", then yes

otherwise, I do not know what "make GPS background app" means

I noticed that when a GPS app is inactive, it stops.

what is "inactive"? what is "stops"? What is "it"?

I want the GPS app running all the time after the GPS starts.

OK

whether the app is running is up to the user and the OS

whether GPS is enabled is up to the user

whether an enabled GPS is on is up to you

OK

I run GeoWebOne demo. It seems not running all the time.

correct

did you read the source code to the GeoWebOne demo?

Yes.

and where is it requesting location updates?

Do you mean my location? USA

no, I meant in the code

if you read the code to GeoWebOne, you will see that requestLocationUpdates() is called in onResume()

and removeUpdates() is called in onPause()

I see.

the vast majority of GPS applications should behave this way, so that they do not drain the user's battery when they are not on-screen

users have been extremely vocal in their dislike of apps that keep the GPS radio on when it is not delivering value

I see.

if, however, you feel that you can convince them of the value, there is nothing stopping you from keeping GPS on as long as your code is running

OK

I have another question.

go ahead

Activity_A has a ListView and imageView. When an ImageView is clicked, it starts Activity_B.

User enters data to Activity_B. How can I send data to Activity_A and update the ListView? I am using Application for global data.

have Activity_A refresh its data from the Application in onResume(), I presume

Yes

Should I send an Intent to Activity_A? or sendMessage?

neither

have Activity_A refresh its data from the Application in onResume()

OK

It seems I have re-draw ListView with new data read from Application.

possibly

Your ListView is being populated by an Adapter

Thank you. I have no more questions.

OK

You have been great help. Thank you.

you're welcome!

I am using TableLayout, but it has scrollViews.

howdy Julius!

Hello

and, re-howdy, David!

I want the last TextView to stay on the bottom on the App. How can I do that?

put it outside the TableLayout/ScrollView, using either LinearLayout or RelativeLayout to anchor it to the bottom of the screen (e.g., android:layout_alignParentBottom="true" with a full-screen RelativeLayout)

OK

Julius: do you have a question?

hi yes :)

I have been playing with the ActionBar and I have found that if I have no TitleBar it doesn't show

however for a phone version of an app I don't want the titlebar

yes, the action bar is the title bar

if I take the no title bar style out of the manifest, the title bar shows temporarily before being removed in my onCreate in an Activity

that's not surprising

:)

unfortunately, I don't think you have a choice

right

you could try using a custom view for the title bar on pre-HC

I haven't played with that

(that's a shame it looks a bit... well not great with it showing and then going in the phone

ohh

you might be able to use a zero-pixel-high layout or something

how does that work?

off the top of my head, I forget

I mean how do I get access to the title bar as a View?

like I said, I haven't used it

oh

right

I think it's a window feature, IIRC

maybe I can ask somone at IO next week

right

ok thanks for the lead

no problem

(still hoping to catch you next week)

you know - just to put a face to the name and all :)

I'll be in semi-incognito mode

oh

oh right

look for the guy wearing the EFF or GNU black ballcaps

electronic freedom f?

er f free

yes

I better check out the logo :)

I'll be wearing jeans so I'll be easy to spot :)

it's just the letters EFF in white on a black ballcap

sweet

modeled after the FBI ballcaps you see on all those imported US TV shows

I was thinking about getting a shirt made that said I <heart> AsynTask

ditto the GNU ballcap, though they went with yellow letters

AsyncTask

but I don't have time :)

ah ok

I'm looking forward to it, but am a bit underprepared

underprepared?

I was hoping to have mucked around with HoneyComb some more

looking at the agenda, I doubt that'll be a huge issue

most presentations will be HC-agnostic

Reto's tablet UIs one probably assumes minimal HC experience

I'd like to do some playing with Fragments before I get there so I can ask some questions

ah, I see

yes, office hours are rather handy

oh right the terminator guy

oh - not of you!

no, no, he's the former California governor

I'm getting pressure to migrate stuff to HC

oh, no, wait, you meant his book cover

yeah

and I haven't really learnt it yet

heheh oh yeah

I meant the book not the muscle man

no disrespect to anyone

ok I better have breakfast thanks for the top - I may be wearing a bright green jersey

I better find out what the weather wil be like

rugby?

it's cold ehre

here

heh (good memory) no

I thought about the ol' silver fern option

highs close to 20C, looks like

but I figure I'll just come across even more small town than I am :)

maybe more 18-19C

hmmm sounds nice

so a light jersey at each end of the day I guess

supposed ot be similar climateto here

but, since my F->C conversion is shaky, you better double-check

:-)

:)

it's easy :) 0 is freezing 100 is boiling - F I'm not too sure :)

must go

catch you later - thanks again.

have a nice day!

howdy, fitz!

what the heck - where is everyone - vacation day?

two have come and gone

out of curiosity, when you sign in mid-chat like this, do you get the transcript of the previous portion of the hour?

or does it just start for you at your sign-in point?

no transcript only when you email

that stinks

I hoped that you'd be able to scroll backwards at least a bit

anyway, David and Julius were each in here for a bit

ok cool - so you moved this time to today - your still on for tomorrow as well?

yes

sorry about yesterday

I'm in Oslo

discovering the joys of being near the Arctic Circle

I am still not getting to see how to run gdata stuff so working on that for now

was so short on sleep that I didn't trust myself in front a chat windwo

er, window

and a B*(&^ of an array problem

BTW, there's a Google I|O segment on using GData in Android

wow and San Fran next week - nice

ya did not get into I|O

unfortunately, the GData session isn't being streamed live

lets hope they live broadcast it

last couple of years, it's taken them a few weeks to get the sessions up on YouTube

oh drag

lots of Android ones are, but not that one

well should be fun - enjoy it - I might take off and pop in tomorrow

ok

cya
