 Here's a simple program that puts a bunch of GridViews inside a
 ListView.

Putting scrollable items inside scrollable items usually does not work
well in Android. I would recommend you use either a GridView or a
ListView.

[android-developers] Re: Where can I catch a point that is assured to be called when a Service is destroied

Who can help?

 Thank you, Mark.

 I read your linked topic, But AlarmManager is not suitable to me.

 My service is not started periodically, it started by broadcast,
 Actually by android.intent.action.PHONE_STATE.

 On each starting, the service should load a big database, this spend
 about serveral seconds, so I don't want to load it each time
 android.intent.action.PHONE_STATE arrive, I leave the service
 runing.

 For each android.intent.action.PHONE_STATE, a UI should be present
 to user while calling, in order to show the UI in front of calling and
 not to interrupt the interaction with phone call, the UI should not be
 a activity, I user WindowManager.LayoutParams.TYPE_SYSTEM_ALERT with
 FLAG__NOT_FOCUSABLE.

 In above condition, except to Service, there is any better class I can
 use? pls advise me.

 If I have to user Service, Where should I do cleaning up and saving
 settings?

 Thank you!

   Where is the rightpoint? pls help me, THANK YOU!

  There is no rightpoint for those scenarios. Your code will not be
  called. Hence, do not wait to be destroyed to clean up and save
  settings.

  And, please do not leave your service running all of the time:

   Here is what I see.

   In AudioRecord.h and in the MediaRecorder.AudioSource, the enum values

   In native code (AudioRecord.h), the values are ..

   Now, if you look at AudioFlinger, any input source, whose value of
   stream type is =
   NUM_INPUT_SOURCES (i.e., 4), we will get an invalid stream type.
   Because of the
   mismatch of the enums, the Java API sets the value of VOICE_CALL
   stream type as 4.
   So, the check fails and we get the failure.

  http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;...

   Fix:
   Set the values of the stream types to be the same in the Java and c++

[android-developers] Re: Controlling my service from main activity

Well, I've done some considerable debugging and testing on this. My
code is based on the examples given with the SDK docs, so it's nothing
different or profound. 
http://developer.android.com/intl/fr/guide/developing/tools/aidl.html

I can confirm that if you pause the activity that called the service,
when the activity is resumed it does not pick up the same connection
object. This means that when you subsequently stop the service, the
old connection is still hanging around (although you can't access it)
meaning the service's onDestroy() doesn't get called. The only way to
make sure the service is destroyed is to destroy the activity too -
which really isn't what I want to do in this case.

Mark, or anyone else, if you have any suggestions I would appreciate
it. Here's the code where the connection is created:

private ServiceConnection m_connection = new ServiceConnection(){

@Override
public void onServiceConnected(ComponentName name, IBinder 
service)
{
m_service = ILocationService.Stub.asInterface(service);
}

@Override
public void onServiceDisconnected(ComponentName name) {
m_service = null;
}
};

 So it seems like the onDestroy() method should be called, unless there
 is more than one connections existing. Is it possible that when my
 activity is resumed, a new connection object is created, making a
 second one hanging onto the service?

Hi,

May be I am missing some where, I am not able to implement it. As you
said I used the simple_spinner_dropdown_item file in my program and changed
the width. Only the radio icons(default which are placed on the extreme
right) move towards text(ie.. left side), but the background still remains
the same.I even changed the themes, and spinner images but still the spinner
drop down occupies the entire width of the screen. I am not able to guess
what I am missing. can you help.

Thanks in advance

Hi,

For the spinner you must be using an adapter. I guess, while using an
adapter you would also be specifying a layout. It would probably be
something like this.

android.R.simple_spinner_item

Extract this file from the SDK location into your project.
..\android-sdk-windows-1.5_r2\platforms\android-1.5\data\res\layout
\simple_spinner_dropdown_item

Change the width of the layout, and use this layout in your code, i.e
while specifying the layout for your adapter.

 I can confirm that if you pause the activity that called the service,
 when the activity is resumed it does not pick up the same connection
 object.

You are the one creating the connection object (private
ServiceConnection m_connection), not Android. If you want to hang onto it,
hang onto it.

If your initializers are getting invoked again, then you were not paused
and resumed, but rather destroyed and recreated. In that case, you should
have unbound from the service in onDestroy().

Android doesn't offer much in the way of wrapping in its built-in layout
classes, other than text in a TextView (which can include links, via
Linkify or other means of creating a suitable Spannable).

You also could use HTML via a WebView, and nix the GridView and ListView
altogether.

[android-developers] Re: Can someone with a Motorola Droid call AccountManager.getAccounts() please?

2009-12-11 Thread polyclefsoftware

Well, if anyone is still following this thread at all...

I'm able to replicate the behavior RoryD describes, but it is still
less than ideal from the user's perspective. Here's what happens:

1) The user opens the app for the first time, clicks a button to log
in.
2) Account Manager tries to get the auth token, returns null and
produces a system notification.
3) At this point, the user would have to return to the home screen,
open Notifications, select the system notification that was just
produced and allow the app access to their user credentials.
4) The user could then relaunch the app, click a button to log in, and
the Account Manager would then be able to successfully retrieve the
auth token and use it to log in.

I really don't want users to have to exit my app to accept a
permission notification before reentering the app. Granted, they would
only have to do this once, but it's still extremely clunky.

A couple of questions:

1) If we're already declaring the GET_ACCOUNTS and USE_CREDENTIALS
permissions in the manifest, and the user is aware of this when they
install the app, why the extra steps of notifying the user and forcing
them to allow the app to use their credentials? Isn't this overkill?

2) Is there a way to take the user directly to the notification screen
when the system sends the notification, rather than have the user
manually navigate away from the app to the notification screen?

Re: [android-developers] Re: clicks to MapView to firing onClick

2009-12-11 Thread TreKing

In that case, what I would probably do is derive a class from
MyLocationOverlay, as you already mentioned, and override the onTap function
(not dispatchTap). I believe this is called whenever the map view is pressed
anywhere, but then only returns true if the given overlay was actually
tapped (to prevent dispatching the event to the other overlays).

So simply:
public boolean onTap(GeoPoint gp, MapView mv)
{
 // Do what you need with current accuracy and location

 return super.onTap(gp, mv);
}

Hope that helps.

 them to much by having to focus on a small button.

 The only alternative I can think of is a send when accuracy is better

 this is never hit for whatever reason?  Also moving forward the user
 might be able to move the icon (if i replace the overlay anyway) to
 make it more accurate.

[android-developers] GPS beacon vs. locked

2009-12-11 Thread stanlick

I am trying to determine whether satellites are being acquired or if a
lock has been acquired.  I can see this with a pulsing vs. fixed dish
icon on the notification bar, but so far I have not quite achieved a
solution in code.

Apparently this does nor necessarily mean LOCK_ACQUIRED?

@Override
public void onGpsStatusChanged(int event) {
if (GpsStatus.GPS_EVENT_STARTED == event) {
//1
setGpsAvailable(true);
}

}

Peace,
Scott

Re: [android-developers] GridView in a ListView: results are unusable the way it is now

2009-12-11 Thread Romain Guy

ListView and GridView are not meant to be embedded within one another
(the same is true with ScrollView.) And when I say they are not meant
to, it's not supported to do so.

On Fri, Dec 11, 2009 at 6:53 AM, Brion Emde brione2...@gmail.com wrote:
 Here's a simple program that puts a bunch of GridViews inside a
 ListView. My original question was about how the list item that has no
 GridView entries, or one row of entries, still has two rows. But, upon
 further examination of the included program, the worse problem is that
 the GridView items that have 3 rows are cut off. The ListView is not
 giving enough space to include the entire height of the taller
 GridView.

 Sometimes the GridViews with 3 rows can be scrolled, sometimes not.
 The intention, in my real code, is to put out a variable length list
 in a grid fashion and it mostly works, but for the scrolling that is
 sometimes required.

 Is it possible to get the GridViews to come out full size, even at the
 expense of all the item views in the ListView being larger? How could
 I do that?

[android-developers] Re: Controlling my service from main activity

Well, we're going right back to the basic fundamentals here! I thought
I had got to grips with this long ago, but clearly not. Here's what's
happening:

If I press the 'home' key, onPause and onStop are called.
If I press the 'back' key, in addition onDestroy is called (that's the
behaviour that has confused me).
If I restart the activity by 'long pressing' the home key, onStart and
onResume are called.
If I restart the activity from the app menu, it is entirely restarted
with onCreate, leaving the other instance of the same activity in the
background. (Again, this is the behaviour that has confused me).

So... is there a way to ensure that only one instance of the activity
can be run, so that when (and however) I start it, if it's already
running that is the one that continues?

[android-developers] Re: AppWidget / Home screen widget and size

2009-12-11 Thread Kaj Bjurman

dip and dp is the same according to the documentation.

dp
Density-independent Pixels - an abstract unit that is based on the
physical density of the screen. These units are relative to a 160 dpi
screen, so one dp is one pixel on a 160 dpi screen. The ratio of dp-to-
pixel will change with the screen density, but not necessarily in
direct proportion. Note: The compiler accepts both dip and dp,
though dp is more consistent with sp.

Correct.

 behaviour that has confused me).

Correct. BACK, by default, will destroy your activity.

 If I restart the activity by 'long pressing' the home key, onStart and
 onResume are called.

I haven't tested that, but I'll take your word for it.

 If I restart the activity from the app menu, it is entirely restarted
 with onCreate, leaving the other instance of the same activity in the
 background. (Again, this is the behaviour that has confused me).

This can be adjusted via some manifest settings.

 So... is there a way to ensure that only one instance of the activity
 can be run, so that when (and however) I start it, if it's already
 running that is the one that continues?

android:launchMode=singleTop may do it, but may not be your problem.

In most cases, you should not care about that other activity in the
background. It will be destroyed eventually, when the Grim Memory Reaper
comes around.

My problem is that I have no idea what you're trying to achieve, which
limits my answers to very tactical ones, directly addressing your
*questions* and not your core *problem*.

For example, from your original post on this thread:

What I want is for a user action (button press etc) to start the
service, which it does. Then I want the user, some time later, to
press another button to stop the service. Which it does.

None of that requires bindService() at all. Use startService() when the
user starts the service. Use stopService() when the user stops the
service. I have yet to figure out why you're messing with bindService() at
all -- not that there aren't reasons to use bindService(), but the pattern
you describe doesn't need it.

[android-developers] Application closes after about seven hours

2009-12-11 Thread kaloer

Hi,

I have a problem with my application. Sometimes, it closes after about
seven hours run because of an exception. I can really not figure out
why this exception is thrown, and I cannot have the device connected
to my computer for debugging in seven hours. However, I've used the
Thread.setDefaultUncaughtExceptionHandler() method to catch the
exception. When the exception is catched, the application writes a log
file to the SD-card with info about this.
The strange thing about this is, that the application calls this
method every single minute, but an exception is only thrown after
about seven hours. Do anyone have an idea about this, or are there any
tool I can use to discover what is wrong?

I have written this log file (method name - class name - line
number)  :

[android-developers] Re: java.lang.OutOfMemoryError: bitmap size exceeds VM budget

You catch out of memory?  I wasn't willing to do that yet, but it
would solve all my problems...

On Dec 11, 7:09 am, Streets Of Boston flyingdutc...@gmail.com wrote:
 If you're nulling your static bitmap in onPause why is it static to begin 
 with?

 E.g. to have access to bitmaps outside of my activity, in classes that
 don't have reference to my activities.

 Or, in case there can be multiple instance of an activity, these
 instances can share 'expensive' data. But this requires something a
 bit more sophisticated than just nulling the static in the 'onDestroy
 ()'.

 In my gallery app i use static caches of thumbnails that are capacity
 limited. These caches manage themselves and don't rely on onPause or
 onDestroy. I do catch OutOfMemoryExceptions then clean these caches
 explicitly and try the operation that threw the execption again. So
 far, this has been working for me :)

  Also what you want to do is probably very different for a game that is
  basically all taking place in one activity and trying to avoid garbage
  collecting at all, compared to your standard Android app with an
  activity per screen.

   However, as soon as you do hold static references to 'expensive'
   resources, be sure to have a proper clean-up strategy. E.g. make sure
   the capacity of your cache of bitmaps is limited. Be sure to set the
   static reference to null when the activity is destroyed or paused,
   etc.

I think my problems might be camera related, so my plan is to stop
using our own camera related activites and just use an intent to
launch the camera, and then read the returned result.

 This is the expected behavior.  Keep in mind that the VM doesn't shut

[android-developers] Re: Controlling my service from main activity

Yes :-) we are going round in circles a bit!

The overiding problem for me is that the behaviours I described above
are causing different scenarios with my service. When I press 'back',
and then return to the activity, a new connection to the service is
created. Which results later in the service not being destoyed when I
tell it to, because there is the old connection still hanging around.
(Then, depending on user actions, I can get a leak error).

Why am I using bindService()? Well I thought I had to, I'm using an
aidl file with methods implemented to get stuff from the service...

On Dec 11, 6:14 pm, Mark Murphy mmur...@commonsware.com wrote:


 None of that requires bindService() at all. Use startService() when the
 user starts the service. Use stopService() when the user stops the
 service. I have yet to figure out why you're messing with bindService() at
 all -- not that there aren't reasons to use bindService(), but the pattern
 you describe doesn't need it.

If this is a local service (i.e., the activity and the service are in the
same project), you do not need AIDL. Use the local binder pattern, found
in the APIDemos, or another variant here:

http://github.com/commonsguy/cw-android/tree/master/Service/WeatherPlus/

You probably want to bind in onStart() and unbind in onStop(). Remember
that the service will run *either* if you are bound to it *or* if somebody
called startService() without a corresponding stopService()/stopSelf(). If
you bind in onStart() and unbind in onStop(), then your HOME button press
will unbind from the service...which will either shut down (if the user
didn't press Play or whatever is triggering startService()) or not (if
startService() indeed was called).

[android-developers] getting the browser to use localhost in airplane mode

2009-12-11 Thread jami

Hi All,

I have been using an application called ankimini that is basically a
flash card application using ase and python.  To cut a long story
short it initiates a server that listens on 127.0.0.1:8000 and you
then view the flash cards using the browser.

This all works fine until you lose connectivity or switch on airplane
mode, then the browser complains that This application requires
network access even though I am only
going to 127.0.0.1:8000.

It looks like the browser checks if you are online before going to the
next page, regardless of what it is, but waits for a minute or so to
see if a connection is established before giving the: you need to be
connected error.

I tried another browser (dolphin) and it was similar, it says
something along the lines of: the page will continue being loaded once
you are back online.

If you have any idea how you can get the browser to go to localhost
when not connected please let me know.

Thanks,

Jamie

[android-developers] about how to detect the usb device in Android

2009-12-11 Thread lidemin

hi all,
now  i have ported the Android to a x86 platform.
And i want to detect the USB plug-in.But follow the information about
the android.intent.action.MEDIA_MOUNTED
in the SDK's DOC, i can't receive the event of the USB's plug-in.

i have checked my code and it can receive the other event ( ps:intent
action) .

Besides, in the CLI, i could mount the USB device to /sdcard but it
couldn't mount automatically.

have seen some source code about the mount and mountlistener and it
should be effective.

who can tell me what the problem is?  and my SDK's version is 1.5.

[android-developers] Re: without Absolutelayout, how to put button on arbitary coordinates

2009-12-11 Thread shomari

After being forced to move away from AbsoluteLayout (not because it
was depreciated, but because of the new screen densities that it
wouldn't support) I choose to use RelativeLayout (although FrameLayout
works the same way).

I was successful after making the following changes to ALL xml files:

1. Change AbsoluteLayout to either RelativeLayout or FrameLayout
2. Change android:layout_x = android:layout_marginLeft
3. Change android:layout_y = android:layout_marginTop

You should also start making more use of wrap_content and
fill_parent.
As well using android:layout_alignParent???=true (works only with
RelativeLayout, hence why I chose it).

Hope this helps

I need to configure the Setting through IActivityManager. But after adding
 import android.app.ActivityManagerNative; and import
android.app.IActivityManager in eclipse,  errors still exist that

ActivityManagerNative cannot be resolved
BackupManager cannot be resolved
IActivityManager cannot be resolved to a type
The import android.app.ActivityManagerNative cannot be resolved
The import android.app.IActivityManager cannot be resolved


when I check android.jar , don't find android.app.ActivityManageNative.class
and android.app.IActivityManager.

how to use them?

/** code **/

import android.app.ActivityManagerNative
import android.app.IActivityManager

Locale l = new Locale(zh, CN);
IActivityManager am = ActivityManagerNative.getDefault();
Configuration config = am.getConfiguration();

config.locale = l;

[android-developers] Application use of Haptics (When to enable/disable - minimizing confusion annoyance)

2009-12-11 Thread Steve Scherer

Is there a general guideline for application developers about when to
disable haptic responses?  I know there are ways to enable/disable
long-press haptics, but if an application was created to use haptic
feedback for other events are there guidelines that application
developers should follow?

For example, if the user was to go into Settings-Sound  display -
Haptic and set that to OFF, should all applications refer to this
setting as a rule of thumb?  From and end user point of view, I would
like to have global control of haptic feedback especially if I find it
to be annoying.  I have seen several postings in the android forums
looking for a global override to haptic responses.  Ultimately, I
think it is a question of should each application provide a menu to
enable/disable haptic support, or should this be more of a global
Setting for the device.  I personally feel applications should refer
to the global setting, but would like to get feedback from other
developers about this.

Reference postings I was referring to:
http://www.droidforums.net/forum/droid-general-discussions/6812-haptic-feedback-dial-pad.html
http://androidforums.com/samsung-moment/13633-how-do-you-disable-vibrating-feature-soft-keyboard.html

Re: [android-developers] Applying effects to camera viewfinder

I want to make a motion-jpeg.

This is not a video format that is supported by the built-in codecs.

One approach I've looked at is to use the preview callback, asking for
a JPEG buffer. Unfortunately, the HTC phones I've tried this on all
call back at several second intervals and give me an NV12 buffer

It should be NV21 (http://www.fourcc.org/yuv.php#NV21), not NV12.

regardless of the pixel format you specify. (Anyone know the
behaviour on a droid?) I can code my way around the NV12 hassle but I

Droid supports NV21 (PixelFormat.YCbCr_420_SP) and YUY2
(PixelFormat.YCbCr_422_I). In 2.0 and after, apps can call
getSupportedPreviewFormats to know the supported preview formats on devices.
But only NV21 is guaranteed to be supported on all devices on all releases.
In 1.6 and before, there is no way to know the supported preview formats and
apps should just use NV21.

can't exactly do much when the callbacks are so seldom; I want around
10 fps.

The approach I was considering was making an opencore codec for
mjpeg. Which leads me to two questions before I start:

1) can third-parties make and install opencore codecs, or is this
strictly locked down? Is it to just drop an .so in the right folder,
or?

2) do the HTC phones use the default encoders? (i.e. will using the
same way the default opencore reference codecs get their pixel buffers
work on the phone?)

thx

[android-developers] Re: Block Switch App

2009-12-11 Thread shomari

I must say that I have really enjoyed reading this thread to see how
both sides view this issue so passionately.  As I've grown in my study
and understanding of the Android platform, many of these issues HAVE
frustrated the hell out of me, but I've come to just accept them.

 And as far as the lock screen goes -- nobody has said that there would never
 be support for third party lock screens.

Why can't this issue simply be resolved by disabling the lock screen
with disableKeyguard() and the android.permission.DISABLE_KEYGUARD
permission.  I've done this in a security app and it seems to work
just fine.  I can create my own Lock Screen with ANY content that I
want.

 Taking over the home key will not be done with a permission, period.

Why this is, I have no idea and I'd have to agree with Greg:

 The current lock app doesn't recognize input from the home button, so
 using that as a reason to not allow any other lock apps is hypocrisy.

Seems to me that this should be up to the users.  Why would Google
even want to override what its users think is best for them, when
they've developed a solid permissions system that seems to work just
fine everywhere else?  There have been countless attempts to build
better security apps, ALL of which can be (as Dianne put it)
BROKEN.  How is this an Android feature?  Just imagine if MS was the
only one allowed to create anti-virus or security apps for Windows
(crazy!)

Anyway, there is after all the option to set a Home Screen replacement
as a Use by default for this action, which I think would solve the
Home Button problem (for Security, Toddler Lock apps and such).

Google has done what no one else in the industry has done, which is to
provide us with the ability to create and use an Open distro, with
little trouble (see CyanogenMod and JesusFreak).  So, in the end,
that's probably the answer.  At least 1 alternative distro should be
popularly supported for users that need just a bit more...

[android-developers] Re: Controlling my service from main activity

That's not *quite* what I'm after... I want the service to continue
running (whatever happens to the calling activity) and then later
(i.e. 2 hours) when the user calls the activity again (could be
recreated or restarted) the service can be bound to, information
collected from it, and then destroyed.

Yes, that sums it up. Does the model you suggest still fit?!

On Dec 11, 6:43 pm, Mark Murphy mmur...@commonsware.com wrote:

 You probably want to bind in onStart() and unbind in onStop(). Remember
 that the service will run *either* if you are bound to it *or* if somebody

 you bind in onStart() and unbind in onStop(), then your HOME button press
 will unbind from the service...which will either shut down (if the user
 didn't press Play or whatever is triggering startService()) or not (if
 startService() indeed was called).

Presumably. Of course, I really wish you wouldn't write an app like that:

http://www.androidguys.com/2009/09/09/diamonds-are-forever-services-are-not/

All you are going to do is get task killers attacking your app because you
drain the battery.

But, assuming your proposed implementation is unavoidable:

-- call startService() whenever whatever triggers the start collecting
data now stuff

-- call bindService() in onStart()

-- call unbindService() in onStop()

-- call stopService() whenever whatever triggers the stop collecting data
now stuff

 Hi, I've made a little testcomponentthat overrides ImageView, called

 However, right now, the text and Doubles that are drawn over the image

 data from the main onCreate function to the myImageView class before
 the layout is drawn?

 I'm new to OO programming, but based on my understanding of 
 this:http://developer.android.com/guide/topics/ui/custom-components.html
 it's possible because ImageView is just like any other class. This
 leaves me with two initial guesses:
 1.  I could generate my test data in the main onCreate, and store it
 in the array's xml file, and then read that xml file with
 myImageView,

 OR 2.  I could extend view instead of ImageView, but because of my new-
 ness, then I would lose the ability to use it in an xml layout sense -
 and that's what I really want.

 Thanks for any tips, or references! I can post code if needed, but
 this is more of an approach question.

 My question was that for Eclair is there a DB that I can register for

 only when a new contact was added, a contact was deleted or an
 existing contact was modified. But in Eclair I keep on receiving
 'onChange even after a call has been made to an existing contact (I
 guess because of the last_time_contacted  field in the DB).

 I tried registering for other DB (like Data and Raw_Contacts) also
 but experienced same issue.

 My question was that for Eclair is there a DB that I can register for
 which will only be triggered if a new contact was added or old contact
 was deleted or the contact name was modified?
 Thanks

[android-developers] Re: Controlling my service from main activity

 Presumably. Of course, I really wish you wouldn't write an app like that:

 http://www.androidguys.com/2009/09/09/diamonds-are-forever-services-a...

 All you are going to do is get task killers attacking your app because you
 drain the battery.

Well in this instance I will be telling the user not to do so, and the
nature of the service will make it quite clear that this would be the
case, they would know not to do it.

 But, assuming your proposed implementation is unavoidable:

 -- call startService() whenever whatever triggers the start collecting
 data now stuff

 -- call bindService() in onStart()

 -- call unbindService() in onStop()

 -- call stopService() whenever whatever triggers the stop collecting data
 now stuff

Ok, will try that - though I seem to remember if I called unBind()
then I couldn't rebind later...

Many thanks.

Okee-dokee. Just remember: users rarely RTFM.

[android-developers] } catch (OutOfMemoryError E) {

Can I ask what Android does with un caught OutOfMemoryErrors that it
wouldn't do if I caught them?  It's really tempting for me to do this:

try {
setContentView(R.layout.result);
} catch (OutOfMemoryError E) {
   outOfMemoryCount++;
 e.printStackTrace();
  finish();
}

If I don't catch the OutOfMemory my activity crashes, but then the
user just clicks the button again and it loads great the second time.
So something happens resulting in the right memory being cleared.

Re: [android-developers] where is my trialing #?

 I'm using Android 1.5_r2. In the following code I was trying to auto
 dial:

 Intent intent = new Intent( Intent.ACTION_CALL,
 Uri.parse(tel:+ **76*1234567890*#));
 activity.startActivity( intent );

 the dial screen come up but the number it actually dialed is
 **76*1234567890*. Is Android removing the trialing #? Or I need to
 use some special escape character to preserve # in the dialing uri?

# is a reserved character in URLs, so that might be your problem. You
could see if %23 works instead of #.

[android-developers] Re: US export law

Not as described.  It is possible to break US export laws from code,
but its hard to do without seeing a big warning first.  IIRC you have
to code your own cryptography and make it too strong.  It's silly, and
I hope the law I'm thinking of isn't actually enforced anymore.
