[android-beginners] Re: emulator can not be powered on

2009-03-09 Thread Roy Zhang
SIR:
 I built it on linux indeed. Following question that I do not
understand: or do u can give me a detail website to explain them ?
1. what`s mean of lunch after all? Is it used to set build enviroment,
such as set TARGET_SIMULATOR=FALSE/TRUE

2. I used make sdk, the sdk folder is generated in
out/host/linux-x86/sdk/...

3. do not understand : cd
out/host/linux-x86/bin/sdk/android-sdk_eng.digit_linux-x86/tools
ANDROID_PRODUCT_OUT= emulator -system ../platforms/android-1.5/images -data
data.img

THX
2009/3/2 David Turner di...@android.com

 Ahh, this is a bit complex to explain, let's cut the details here:

- make sdk will not do what you think. Building the SDK should be
done on Linux or Darwin with something like make PRODUCT-sdk-sdk.


- emulator will not do what you think either. Because you called
lunch, the emulator will think by default that you want to run a system
image, not a sdk one.

- By the way, building the SDK is only directly supported on Linux and
Darwin. For Windows, we have to generate a Linux installation tree, then
copy Windows-specific binaries into it for a few select tools. Don't try
this at home, seriously...

 On Linux, here's how I rebuild and immediately test the SDK:

 . build/envsetup.sh
 make PRODUCT-sdk-sdk
 cd out/host/linux-x86/bin/sdk/android-sdk_eng.digit_linux-x86/tools
 ANDROID_PRODUCT_OUT= emulator -system ../platforms/android-1.5/images -data
 data.img

 Note that my username (digit) is part of the generated sdk directory, so
 YMMV.

 Hope this helps

[android-beginners] Connect 2 Androids Ad-Hoc or via Hot Spot ?

2009-03-09 Thread Daniel Weidele

Hey guys,

i need the possibility to exchange messages between NEARBY Android
Phones.

This could mean, if they are close enough together, that they build up
a kind of ad-hoc net, or if one is connected to a hot spot, and
another gets into the hot-spot net, that the hot spots tells one that
there's another one available, so that they can send messages.

I have no idea how to connect to a Hot Spot or How to set up ad-hoc
net.

I tried with Connectivty Manager and WifiManager - the GetScanResults
Method always returns null, even if i actually ARE in a zone of hot
spots...


When replying, would be nice to see some code snippets!

[android-beginners] Merging two apps

Hello All,

I built a testing ground application that does the Frame by Frame
Animation and I built a full app that cycles through some images and
sounds using the onclicklistener which utilizes if statements.


I want to have the frame by frame animation code run inside of one of
the if statements in my other app when it's called but I cannot figure
how to merge the code

Any ideas would be helpful.

[android-beginners] Dynamically adding images to a gallery

2009-03-09 Thread carnegie

Hello everybody

I'm trying to create a dynamic gallery, where the pictures are taken
from the links in a txt file. Since the txt file can be often updated,
there is a possibility that the amount of images in the gallery
changes every time the user would restart the app (or click on a
button). My question is now: Is this technically possible and if yes,
how could I implement such a feature?

I'd appreciate any help on this problem,

[android-beginners] Re: AlertDialog does not show

2009-03-09 Thread Tommaso

Hi Mark,

it is not due to the regexp in the code and the if-else...
The problem seems to be that this is not the Main Activity, but a
subactivity!
When I do the same thing in the main activity, it works.

I have found tons of examples, but always with the easy constellation,
i.e. when you want to show alerts in the main dialog.
More, I am now trying to fix this with the Handler, implementing the
runnable interface on the very activity and trying to work with
Thrad.class.

Any other ideas? I cannot believe that nobody is facing this
situation?

 I need a simple auto complete box and when you start typing it brings
 up a list of all the names in the contacts with the numbers below the
 name just in case some names have multiple numbers. When you select
 the contact it will place the name in the textbox with a semicollon
 after it so that you can start typing again to add another recipient.

 Once the recipients have been selected and a button clicked i need
 only the telephone number put in a string so that i can pass it to a

 Its exactly the same as the default to in the messaging app pre

Hi Christian,

I wouldn't do that!
The framework, I am sure, has means to implement the behaviour we
want. By doing some kind of hacks, you are running into trouble later.
Also, you don't know about side effects, like memory, UI, etc...

I found ou that we will need a Handler, Looper and Thread.

Also, I will ask this in the more advanced groups.

I'm no expert, but from what I can tell, the putExtra() methods on
Intent accept primitive types, Serializable objects, and Parcelable

Primitive types and Serializable objects will be copied.  I think
Parcelable objects are copied as well.  You might be better off

[android-beginners] Re: How to format time in millis to human readable?

2009-03-09 Thread Steven Farley

Just out of curiosity, has anybody tried using Joda Time (http://joda-
time.sourceforge.net/) in an Android application?  The Joda API is
much better than Java's built-in Date and Calendar classes.

++Steve

 There may be built-in methods for such things as 5 minutes ago but I
 don't know any yet.

 for the current time in human-readable form, using some default date
 display format (which may or may not be dependent on user-preferred
 locale and date format selection, this remains TBD for Android), the
 fastest way is:

 +new Date()

 and with a given time in millis, it would be as in:

  Build.TIME +Build.TIME+ = +new Date(Build.TIME)

 Calendar is recommended for conversions (e.g., time zone changes) and
 for other calculations with dates, such add, after, before, compareTo.

 When you create a Calendar, it is already set to the current time:

 Calendar cal = Calendar.getInstance();

 is usually equivalent and preferable to:

 long millis = System.currentTimeMillis(); //don't do these 4
 statements
 Date date = new Date(millis);
 Calendar c = Calendar.getInstance();
 c.setTime(date);

 And if you need to use SimpleDateFormat, because for example you don't
 want to use the default format you get from Date, then take special
 care because some implementations are not multithreaded, therefore
 unless you know for sure that Android's implementation is
 multithreaded, then don't cache the instance and use a local variable
 that only lives in the method, don't use a field. This makes
 SimpleDateFormat somewhat expansive to use but usually it is only used
 for some UI work (i.e., not background work), therefore using it may
 be OK for many apps.

 happy coding

String humanReadable = month + / + day + / cal.get(Calendar.YEAR);

But really, you should be using SimpleDateFormat, I suppose...

[android-beginners] Re: Images from URL into Lists

2009-03-09 Thread Joseph Arceneaux
Thanks, your blog posts are very helpful on constructing more elaborate
lists.
I'm still in the dark, however, about fetching images - they're .png files
fetched via URL and I plan to cache them.  I could put them on the SD card,
or in the database.  They are, hopefully, thumbnails of the appropriate
size, but I may need to shrink them 10% or so.  Is there a standard paradigm
for doing this?  All the image manipulation code I've seen so far refers to
images already on the platform, e.g., R.drawable.image3, but I've seen
nothing about converting a data stream into an icon.

Thanks again,
Joe

  1.  How to go about fetching the image from the URL

 That depends on lots and lots of factors, such as:

 -- Do you need to save the images to the SD card as a cache or for later
 use?

 -- Do the images need to be converted to thumbnails?

 -- How many of these things are we talking about?

 Lots of images that are not already thumbnailed means lots of RAM and
 lots of storage and lots of bandwidth, which means lots and lots of pain
 and suffering.

  2.  How to get the image into a List next to some text

 I have several blog posts on this topic over at AndroidGuys.com:

 http://androidguys.com/?s=fancy+listviews

 In particular, you need to be very careful about recycling the list
 rows, so you do not wind up re-fetching the images all the time.

 Note that some of these posts are from last summer and the M5 SDK, so
 they may require some tweaks to work with the 1.1 SDK. Also, forgive the
 formatting, as AndroidGuys moved to a new host and so some of my old
 postings are a bit messed up.

[android-beginners] Re: can accelerometer sense short and long motions?

2009-03-09 Thread Jordan Frank

Short answer: No.

Accelerometers measure acceleration, not velocity. So it might be
possible to monitor the acceleration, use that to infer the velocity,
and then measure the time until the corresponding negative
acceleration, but this is very error-prone (due to the fact that
you're doing numerical integration over discrete samples, and the
sensors are fairly noisy).

The adb daemon runs as a normal user.  You can adb shell and then
su to become root.

This does mean you have an extra step: push the file to /sdcard and
then copy it over.  This annoyance will be addressed in a future
release.

[android-beginners] How to prevent repositioning of a dialog

2009-03-09 Thread Michael Bollmann

I got a toplevel dialog window
When i use setVisibility(View.Visible) on a part of the layout that
had the attribute View.Gone before the whole dialog is repositioned/
centered.
How do i prevent that?

I want the new part of the layout to be visible but also keep the old
position of the top level window.

[android-beginners] Filling a large database causes crash

2009-03-09 Thread NFSpeedypur

I am trying to on first start up fill up a sql database with the
default values.  This database is around 9000 entries and it is
causing the app to go over the 16MB heap.  I am trying to find a way
to do this so that it will not cause this over flow.

At the moment I am running the 9000 inserts, 1 after another in a
thread.  Are there any other suggestions?

[android-beginners] accessing information from browser, in an application

2009-03-09 Thread Shani

I am editing the pre-existing zxing Barcode Reader code so it can
voice itself for blind users.
I know how to use Text to speech in the app.
Right now I am at the step where after the barcode is read, it then
opens a webpage in the android browser - it sends the product number
to google. What i want to do is be able to read from that webpage-
whether its from the DOM or just being able to get the source for the
page.

Here is where the intent is launched:

Uri uri = Uri.parse(http://www.google.; +
LocaleManager.getCountryTLD() + /products?q= + upc);
launchIntent(new Intent(Intent.ACTION_VIEW, uri));

Do I need to use android.webkit somehow? Or is that just for making my
own webpages in the browser?
No clue how to proceed right now. Thanks, any help is very appreciated

shani

[android-beginners] Re: Make a button from an image (PNG)

2009-03-09 Thread xspotlivin

Ok, thanks for the replies. I'm going to describe what I'm trying to
do better, because I'm still unsure of the solution, and I could
really use some help.

I have a clock application (how can you attache an image). For each
shaded region I want to place a button on top of it (a different
button depending on some xml data). I don't know how to create a
button from the attached image and then draw it in the correct spot.
My xml data has the time of the shaded region, so I can figure out
what angle to put the button. Below is the relevant code from my
ClockView class. The for loop is looping through each element in an
xml document (which I pass from the activity class).

Java:
public class ClockView extends View {

 protected Document clockXML;

 public ClockView(Context context) {
  super(context);
  this.setBackgroundDrawable(getResources().getDrawable
(R.drawable.clockbackgroundwithoutnames));

 }
 @Override
 protected void onDraw(Canvas canvas) {

  // Clock-size rectangle to draw compliance windows
  RectF clockRect = new RectF(86, 6, 394, 314);

  // Create a node list containing each reminder
  NodeList reminderNodes = this.clockXML.getElementsByTagName
(Reminder);
  int reminderLength = reminderNodes.getLength();

  // Loop through each reminder drawing compliance windows
  for (int i=0; i  reminderLength; i++) {
   String timeScheduledString = reminderNodes.item
(i).getFirstChild().getFirstChild().getNodeValue();
   float timeScheduled = Float.valueOf
(timeScheduledString.trim());
   String complianceWindowString = reminderNodes.item
(i).getFirstChild().getNextSibling().getFirstChild().getNodeValue();
   float complianceWindow = Float.valueOf
(complianceWindowString.trim());
   String administered = reminderNodes.item
(i).getFirstChild().getNextSibling().getNextSibling().getFirstChild
().getNodeValue().trim();

   float compStartAngle = -90 + ((timeScheduled*360)/24) -
(complianceWindow*15);
   float complianceSweepAngle = (complianceWindow*2)*15;

   // If we are in the daytime.
   if (compStartAngle  90  compStartAngle = -90) {
// If a reminder is scheduled in the daytime, but
window overlaps into the night.
if ((compStartAngle + complianceSweepAngle)  90)
{
 // Compute new angles and sweeps
 float startAngle1 = compStartAngle;
 float sweepAngle1 = 90 - startAngle1;
 // Draw for daytime
 canvas.drawArc(clockRect, startAngle1,
sweepAngle1, true, this.amColor);
 float sweepAngle2 = complianceSweepAngle -
sweepAngle1;
 // Draw for nighttime
 canvas.drawArc(clockRect, 90, sweepAngle2,
true, this.pmColor);
// Else, just draw normally.
} else {
 canvas.drawArc(clockRect, compStartAngle,
complianceSweepAngle, true, this.amColor);
}
   // If we are in the nighttime
   } else if (compStartAngle = 90) {
// If a reminder is scheduled in the nighttime,
but window overlaps into the day.
if ((compStartAngle + complianceSweepAngle)  270)
{
 // Compute new angles and sweeps
 float startAngle2 = compStartAngle;
 float sweepAngle3 = 270 - compStartAngle;
 // Draw for nighttime
 canvas.drawArc(clockRect, startAngle2,
sweepAngle3, true, this.pmColor);
 float sweepAngle4 = complianceSweepAngle -
sweepAngle3;
 // Draw for daytime
 canvas.drawArc(clockRect, 270, sweepAngle4,
true, this.amColor);
// Else, just draw normally.
} else {
 canvas.drawArc(clockRect, compStartAngle,
complianceSweepAngle, true, this.pmColor);
}
   // If a reminder is scheduled in the early daytime, but
window overlaps into the nighttime (backwards)
   } else {
// Compute new angles and sweeps
float startAngle3 = compStartAngle;
float sweepAngle5 = -90 - compStartAngle;
// Draw for nighttime
canvas.drawArc(clockRect, startAngle3,
sweepAngle5, true, this.pmColor);
float sweepAngle6 = complianceSweepAngle -
sweepAngle5;
// Draw for daytime
canvas.drawArc(clockRect, -90, sweepAngle6, true,
this.amColor);
   }

   // I want to create the buttons here for each
reminder

  }
 }

}

I'm sure if
