[android-developers] Re: Communication with Flash (swf)

[sleith]

Hi,
really thanks for your answer :)
Did you ever tried this before?
So the android app will continuously looping every x second to read a
file for any input right?
Is it really possible? i mean for swf to write and read a file in
android platform.

Maybe if you have a trial source code, it would be great if you can
send it to me for sample :)
Thanks

 One way you can do is via a text-file..
 write and read from text-file in android code...and you can do same with
 your flash swf for communication..
 i think direct way is not possible as 2 are very different technologies.. :)

 Any prob..do tell.. :)

hi,
do you found the solution on how to communicate with flash?
big swf file i think is not an issue, just an issue to the memory, as
it needs to be loaded into web browser memory, i think.

[android-developers] bring task to front

[sleith]

Hi,
i know this question has been ask many times, but i still don't find a
solution...  need helps :)

I tried to handle about the hold screen button that makes screen off.
Somehow the game is exit because of this.
Then i try using broadcast listener for screen on/off and when
detecting off the app will call moveTaskToBack(false) which
successfully saved the state of the game.

When i turn on the screen, I tried launch manually from homescreen and
the game can resume the previous state (this means moveTaskToBack is a
success).

Because i need the phone to automatically bring the game to the front,
i try to make a background service that receive command from the
screen listener to launch intent.
But the game start from the beginning instead of resuming last state.

So what i might missed is how to launch an intent to bring from back
to front just like we run the app from homescreen.

Need help, thx .

intent.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT |
Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY|
Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

i also tried previously:
Intent intent = new Intent(context, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

[android-developers] install to sdcard failed

[sleith]

Hi,
I'm trying the feature android:installLocation=preferExternal
my asset files is 155MB and sdcard has around 2GB.
When trying to install, it seems the apk file is installing to the
internal phone storage instead to the sdcard.
This results : Unable to upload file: No space left on device
When i tried to remove some asset files to small size 20MB i think,
it can be installed to the sdcard.

Can anyone help me out why it's installing to the internal phone
storage instead to sdcard?

 Nothing in the rules saying that it would not be judged outside the

 You don't detect on touch for app widgets. You can, however, detect
 clicks, via setOnClickPendingIntent() on RemoteViews. AFAIK, this works
 for all View classes supported by RemoteViews.

 Probably not. I do not have an HTC Hero and so am not familiar with this
 feature. However, there is nothing in the RemoteViews API that supports
 gestures AFAICT.

 Also, just because it is on the home screen does not mean it is an app
 widget, just as the Google search widget on regular Android devices is
 not an app widget. It could be written as a part of their actual home
 screen implementation.

[android-developers] Re: launch activity like phone call

[sleith]

Hi,
wanna ask again about Mark's first warning:
 Your service will not be running for very long once the screen turns
off. The phone will go to sleep, and your service will stop running
when
the phone turns off the CPU. 

when the phone turns on the CPU again, will the service restarted
automatically?
if it won't, how to know if the CPU has been turned on/off?

thanks

  First, the warnings:

  1. Your service will not be running for very long once the screen turns

  2. Doing things that wake up the phone are bad for battery life. See

  and your service-spawned activity steals the foreground, they may have
  quite a few profanities to fling in your direction. An incoming phone
  call is one of the few things users might tend to agree warrants such an
  intrusion...and I suspect there are still many a curse word used when
  users get interrupted, even for that.

  Hence, before you even bother with any code, you need to really make
  sure that this is what you want to do, and consider offering user
  preferences to disable this functionality.

  All that said, you will want to look at PowerManager.WakeLock to arrange
  to keep the screen and CPU on for a while. Which leads to:

 Restarted? A running service will start running again, but to me
 restart implies it was destroyed and recreated, which does not happen.

 When the CPU shuts down, everything freezes in mid-operation. When the
 CPU starts up again, everything continues from where it was.

 Again, I strongly advise against having services run indefinitely. A
 well-constructed service only runs when it needs to (via an alarm) and
 can arrange via a WakeLock to keep the CPU running for the short period
 it needs to run. See more at:

 This is deliberately not supported.  You can start the service when the user

[android-developers] Re: Hmm... at last ADC2 is out of our way ... tell about your app and experience

[sleith]

Hi
It's the first time i release application in Android. My app is
ClapCard (in market i submit it as Clap Card, because when using
ClapCard title it said the app has already exist, maybe they compared
to the app in adc2 too)

I started 3 months ago, doing the app in my free time (i have full
time job and part time job).
it's a 3 months with less sleep (averagely 5 hours sleep)
Glady i made it in time to submit my app.

My app is a social type. It's about creating and sharing animated
card. It's not like cards in web site tough, because it uses phones
cappabilities like web, map, vibration, sms, email, etc.
Because this is my first release, this morning i submitted it to the
market hoping that people like it and can create and posting cards to
make it more crowded in community. I myself posted 2 cards only, still
has a lot of works to do the tutorial page in website
(www.clapcard.com)

It's a real fun experience to do all the stuff since this is my first
app available for public ^^
I'm planning to make a puzzle like game after completing the website.
(will be my first experience creating game too...)

 Augmented Reality. I've got a comp ed of AugmentThis! in the running.

 This round I didn't stress over the ADC, for a number of reasons, not
 the least that PURE LUCK will play a big role again. So I got the
 release candidate ready about a week before deadline. Of course
 there's always room to squeeze in new features and apply more polish.
 Like all dedicated devs I will remain eternally unhappy with the
 product, but assuming that the evaluators will not sniff out all the
 corners anyway, I spent the rest of the time testing, which turned out
 to be a good use of the remaining time.

 Two remarks:
 As -v- has found, it takes a long time to get Android dialed and is
 decidedly challenging, in spite of the cheerful assurances in the
 various videos on Android's Google Code page. Seemingly trivial things
 can consume huge amounts of effort. Which isn't a problem, Android is
 powerful, with broad and deep access to the devices' capabilities (in
 case you haven't noticed).

  Your app name and description, web link if any, experience with

  And do you feel that there would have been more submissions than in
  ADC1?
  Is the competition going to be tougher or less profound as you were

CraigsRace: what is Gonorrhea? i googled it and in wiki said its
bacteria?
hehe i choose that name because clapcard.com domain is available and
the names resembles to the game i played when i was a kid. (dunno if
in your country has it's game, it's by tossing card with friend, who
got upside front win the game).

 Tasker let's you link any Task (action set) to the Contexts

 should run.

 Send an SMS at 3:15 Monday, make per-app settings or locks, map camera
 button to a menu, launch music app on headphone insert, timelapse
 photos, encrypt on-the-fly, the list is endless!

 Glad I didn't make a game now, seems to be a crowded category!

 I'm grateful to Google for organising a fun competition but was a
 little dissatisfied with not having enough time to develop and well-
 test a non-trivial application from scratch. It's also not possible to
 submit bugfixes after the deadline, and of course I'm discovering
 hundreds every day now...

 I had some test code for the location context which vibrates the phone
 every time the coordinates change: forgot to take it out of course.

 With 5 hours to go (2am in Europe) I found my widget icons were
 disappearing after a few minutes for no apparent reason: it was comic
 at first but became less so as time wore on and I couldn't fix it
 (never did find it...)

 Rud: bad luck, I was also worried about catching something in the last
 few weeks, would have been a nightmare!

[android-developers] Re: weird drawing on bitmap to canvas

[sleith]

thx for reply
did u mean font's paint?
i believe it's not that the font is cannot be drawn.
i think it's the position of the position 0,0 of the bitmap is not
really 0,0 (it's out of bounds)
because when i move the position of bitmap (bitmap.translate) with
some x and y, i could see the text and text background is drawn.

[android-developers] Re: strange behavior on rotating and scaling text

[sleith]

thx for the reply
how about the rotating? is it like scaling?

On Jun 22, 11:13 pm, Romain Guy romain...@google.com wrote:
 Hi,
 This is actually normal. Scaling fonts does not necessarily lead to a linear
 effect. Based on the font size, the text renderer can (and will) change the
 spacing, the antialiasing, etc. to improve on readability. If you want to
 scale text linearly you should turn the text into a bitmap first. If your
 animation is implemented using Views, you can simply enabled the drawing
 cache of the animated view.

  hi, i'm trying to animate text, but strange behavior happened when i
  tried to rotate and scale.
  When rotating, the text width becoming wider and narrower randomly
  When scaling, the text y position is going upper.
  i've test with image, but image works perfectly. don't know why text
  is not.
