Actually, the first part is not true -- you just have to use the right
'this'. Just use MyOuterClassName.this and all will be fine.  You
could also copy it to a final variable but there's no need since Java
provides this mechanism for just this situation.

[android-developers] Re: In-App Purchasing and the Market Agreement

Let me point out that the code that I posted doesn't delete without
user confirmation. It just takes the user to the system's "delete this
application" screen under "Manage applications", where they can choose
to delete or not.

I don't know of a standard way to delete an application without user
confirmation! Even if you can do it, I'm not sure you wouldn't screw
up the package manager, so I wouldn't recommend it.

That's on top of your user-experience reason, which is the main reason
to do it this way, if at all.

[android-developers] How to read Gmail programmatically?

2010-03-27 Thread Ali Chousein

Hi,

I'm trying to query the e-mails from my Gmail account in source code.
I've tried various combinations for the URI but the cursor returned is
always null. Has anyone managed to retrieve emails programmatically
from Gmail?

Some combinations I tried for the URI are below (as I mentioned above,
the cursor which is returned is always null):

Cursor cur = this.getContentResolver().query(Uri.parse("content://
gmail-ls/conversations/@gmail.com"), null, null, null,
null);
Cursor cur = this.getContentResolver().query(Uri.parse("content://
gmail-ls/inbox/@gmail.com"), null, null, null, null);
Cursor cur = this.getContentResolver().query(Uri.parse("content://
gmail-ls/@gmail.com"), null, null, null, null);
Cursor cur = this.getContentResolver().query(Uri.parse("content://
gmail-ls"), null, null, null, null);

I'd appreciate any experience you could share.

-Ali

It may be less expensive for you to just buy a battery than to waste
time trying to get one from Google, who may not exactly have a bucket of
batteries on hand for these sorts of problems. They're $11.47 on Amazon.

I did see that and tried to find a link for replacement. No luck so
far.
That link will just redirect you to the Droid Ads page. \

Local Verizon representative refused to replace the battery for me
since she cannot find
the number of the phone in their system. And she asked me to check
this with Google.

I want to obtain the index of the selected item in a spinner.

I am aware of the method getSelectedItem() which returns the item

selected item.

Something equivalent to the setSelection(index) to set the selected
item.

Of course I can get the selected item and compare it against the array
of items to obtain the index, but I hope there is a better way of
doing this.

Thnx.

Re: [android-developers] Re: In-App Purchasing and the Market Agreement

Good point Kevin

Although we can't just look at this from the coder "implementation" point of
view (my website, using paypal, market place etc). We have to think how
people buy crap.
If the highest chance that they will have an account with Market place then
that will makes a big difference for how many people buy additional content
for your game. For the simple fact of impulse buying.

If all they have to do is click "ok", there is a lot lower chance that they
actually think much about it (especially if you charge like .99). They are
caught up in your game its a two second click. Trasaction done.

If they have to stop to pull out their cc or look up a paypal account then
they actually start to think about that transaction. "Do I REALLY want to
pay .99 for this? Eh...maybe not."

Its not being sneaky, it's just how people shop.

I know. I have done it.

Re: [android-developers] Re: In-App Purchasing and the Market Agreement

We must be on the same wave length because I am ready doing what you just
explained. :-)

When in install app (I started calling them modules in my code) is download
I  check the db, if that character is there then it updates that character
in the DB if it is not then inserts the character info. It also inserts it's
time stamp and its package name. On start up for the MAIN app it will cycle
though the package names of the installed "modules" and if one is over a
week old from install it will ask the user if they wish to remove it (but
make it clear this will NOT uninstall the character if they do). If they
decline it will state that no more notifications will ask to remove it and
it will remain installed until the user deletes the character (which also
removes the module for that character at the same time). I will NEVER
uninstall a module without checking with the user.

Yep the main app is free and it will come with TWO characters because two
characters can be loaded at the same time and interact with each other which
I want the user to experience this to make getting additional characters
more appealing. In the app itself where the installed characters are I have
a little "mini" webview set up which I links to one of my webpages where I
plan to post "new" characters. So when they use the app even without going
to search for new ones they will know of any new characters that I just put.
If you want my code snippet I can send it to you.
i.e. my own banner I guess.

I agree the main thing about going though Market place is that it has the
highest chance that the user probably has an account (compared to maybe a
paypal etc). Which is what we developers want.

It would be great if we could get their checkout info but I would say that
is a HUGE security risk and I don't see that happening.  Besides why would
Google do that? They get 30% if people go though them? They have no
incentive. What could be done is what was suggested is that they provide an
API so people can use to check out THOUGH Market Place. But honestly I don't
see that happening either at least not for awhile.
 Heck 2.1 took forever to come out. So going the route I am is the only way
I see how me (or someone) else can go through Market place, for awhile at
least.

I think I can get my character stats. I can keep track from my site where
they browse the characters, when they click the link to buy one (which links
to Market Place) I can track that I am thinking. Also Flurry can probably
help. I just started learning it.
www.flurry.com

If (big IF) mine is a success then maybe you can gain from my experience?
Although I probably have about another month to two before I can finish code
and test.

Speaking of which, I need to do serious testing in starting in about two
weeks. Has anyone used Device Anywhere? They seem to have a special setup
for  independent developers.

https://www.deviceanywhere.com/Independent%20Developer/Independent%20Developer_virtual_developer_lab.html

I watched the video and seems like a great idea for testing:
https://www.deviceanywhere.com/onlinedemos/

I just wanted to get some feedback on anyone that tired it?

Thank you

Well, it's obvious that these 2 methods are blocking your UI thread
which makes it starve:
1. i.getShortDescription()
2. Utils.getTimeLeft(i.getEndDate())

If you'd explain in more details what these methods do, perhaps there
could be come kind of solution to your problem.

Agreed. AFAIK, permissions are applied to the application as a whole,
whether that is existing code, code loaded dynamically, or code created
directly on the device by butterflies.

JARs can be downloaded (see Mark's post earlier), loaded by the class
loader and run.
However, i think that these JARs must oblige by the permissions given
to the APK that downloads and executes them.

Re: [android-developers] Re: Timer / threads / reliability

The stutter, from what I've picked up on other threads, is as Mark said, due
to various other tasks, apps, and more likely garbage collection kicking in
randomly. One thing that seems to be a common thread for most "real-time"
like UI updating games is to do some sort of time based setup. I forget the
details, but basically on each iteration, you figure out the current time,
subtract the last "time" that was stored, that tells you how much elapsed
time has passed. You use this value to adjust all your UI elements so that
rather than seeing a hiccup with the UI, they UI elements themselves "speed
up" at various times. Or..maybe speed up isn't the right word. But lets say
you have a UI element moving from left to right, 1 pixel per second. A GC
hits and causes a 3 second delay. Your UI element hasn't moved for 3
seconds. In the time based method, you would instead move the UI element 3
pixels so that it would be where it should be. The hiccup would still be
noticeable.. but at least your UI elements will be where they should be,
rather than lagging behind where they should be causing more problems.

There are some threads, and Robert Green and some others have info on here
on how to do it. I've yet to really figure out how to apply the difference
between two frames time stamps and apply it to the world-coordinate system
of a View, for example to make sure a UI element moves to the right
position.

If you are making a sort of game, one of the other important things to do is
do NO creation of objects in the loop. Do all pre-allocation of elements,
objects etc before your loop starts.. or between levels, etc. That makes
game levels generally small in size based on the very limited 16MB ram (or
is it 24MB) you can use for game + images + code... but at least if you can
avoid any sort of object allocation/deallocation during the loop, you can
put off the GC process longer. At least for your game. There was a thread
that was pretty deep on the issue of background services running that could
also trigger a GC and cause your game to hiccup.. and the general solution
to come of that was Google needs to make some sort of "real-time" game mode
so that games that we see on iPhone will be possible on Android. Right now
there seems to be no way to guarantee smooth real-time-ish games on Android.
Some do a very good job tho.

I am curious tho.. can your app download a .jar file and dynamically load it
and use the code in it? I would guess not, but not sure how Android
prevents? I am thinking along the lines of virtual goods. Not that virtual
goods have to be written code.. ideally they would be some sort of

say plugins to a browser for example... is that even possible or does
Android's classloader hierarchy completely prevent this ability to

Re: [android-developers] Re: In-App Purchasing and the Market Agreement

Hmm.. just looked up google checkout.. turns out paypal and google checkout
charge .30 + 2.9%.. so you're still stuck losing 30% for a $1 fee.. actually
2.9% more. So what, .33 per toon. Still.. not a big deal if it's utilized..
making 67% or so is great, especially if more and more people buy virtual
goods.

Re: [android-developers] Re: In-App Purchasing and the Market Agreement

Got an idea for the deletion of add-on toons for you. Use a simple sqllite
db on the device... when your main app finds/installs a toon, log a little
date in the db (or some other way). Every time your main app starts up, just
scan for any rows.. if any are there, check the timestamps... if it's after
2 days (maybe 3 or 4 to be safe), uninstall the .apks at that time.

HOWEVER, something occurred to me. Programmatically uninstalling .apks
without the user knowing may not be advisable. Even tho the toon still works
in the app for them, I would suspect most users, if they wanted to delete it
(or otherwise look at stats on it), they would go thru the settings/manage
applications route, and if they can't find it they may wonder what happened.
Trying to explain to your end users that after a few days the .apk they
bought/downloaded/installed will be uninstalled to "free up room", may be
too much text for a simple toon purchase/install. Maybe not.

Another thought..doubt it's possible.. and I still haven't paid for an app
on android yet so not entirely sure how this works. I thought you'd set up a
google checkout account.. being android and google and all. If that is the
case, then like you said, it's likely that a user will have an account
already.. or at least is more willing to submit their personal info setting
up a gogle checkout account over some in-game form you provide. Now, I don't
know how viable this is, but if the user already has a google checkout, is
there a way to obtain their checkout info... in-app/game, without requiring
them to fill anything out? This way, you could avoid the .apk market route,
you earn the extra .30 per toon, you host it, you keep stats on downloads,
which toons are more popular than others, etc. Tons of stuff you can control
from this aspect of it. If a user already set up a google checkout account,
how hard is it to utilize this in-app/game so that you can use it to charge
and then download in-app/game right away? If they haven't set up an account
to buy anything on market, they are going to have to fill in that info
anyway to buy anything. Actually.. come to think of it.. if you charge for
your main app..they already set it up. I would have thought the info would
be in some way available..not their private stuff, but the google checkout
info, so that you could utilize it somehow? I'll have to look into it more
as this is how I would do it.

Another thought..perhaps to get more virtual toon sales, give your game away
(if you aren't already), with 1 toon, and put your own little splash-screen
"ads" for other toons as the app loads up. This may interest users in
supporting your app and buying even more toons than if they already paid for
the app. Also, look at custom creation of toons/avatars.. for perhaps a $2
charge for example. Again, not at all clear on your app and it's ideas, but
just some food for thought on how you might make a little more from it.

I do not know what you are referring to here. Some bitmaps (e.g.,
nine-patch PNGs) are designed to be resized.

What is a "skinned view"?

In some cases, you will need multiple images for different screen sizes
or densities. In some cases, you can use nine-patch PNGs for resizing.
In some cases, Android's built-in bitmap scaling will be adequate. In
some cases, you will want to switch to creating Drawable resources in
XML (e.g., define your gradients that way, rather than doing so in a
bitmap).

Here is the documentation on multiple screen sizes:

http://developer.android.com/guide/practices/screens_support.html

Here are several blog posts on the subject:

No droid, but I have the EU equivalent Milestone. It had some USB issues 
under 2.0, but most of them were cured with 2.0.1 - which one did your 
Droid come with? The remaining issues I experience are:


1) Occasionally (say after about a week of use) the it will fail to 
recognize the USB cabel, and hence no charge indicator etc. Reboot 
helps. I *THINK* this only ever happens after I've been debugging and 
unplugged the cable while still having the debugger connected. Possibly 
a bad habit, but I never had a problem doing that on the G1.


2) It also seems that my extended USB cable will often glitch (the sound 
indication makes it very obvious) - since it isn't the original I guess 
I can't complain, but again I never had this problem with any of the 
cables I used with the G1.

[android-developers] How to handle imaged background and buttons on different size/proportion displays

2010-03-27 Thread Gabriel Simões

Hello,

Right now I´m working on the UI of my first app and I´d like it to
work on as many different devices as possible.
I´ve read on the net about Android´s rule not to resize bitmaps on
views (background, buttons, etc), is it true? Does android rescale
skinned views sizes the same way it resizes the default ones?
Also, if not, how can I handle the more than 5 display sizes using a
background image and skinned buttons and scrollers (horizontal bar)?

Thanks,
Gabriel

[android-developers] Re: Modifying audio in real time

2010-03-27 Thread Gabriel Simões

After calling play you need to keep calling write so you can feed
AudioTrack´s internal buffer and keep the audio playing. Then, before
you call read you can process your stream the way you want.

About upsampling, downsamplig: it´s a tecnique for changing the
samplerate of a signal trying to modify it as little as possible. When
you downsample you lose information; when you upsample you interpolate
to try to figure out what the information would be since you dont have
it.

For example, if you have a stream sampled at 10khz and want to
downsample it to 5khz (which will play faster at your AudioTrack 10khz
object) you just need to use the even or odd samples, and discard the
rest.

Hope it helps,
Gabriel

Re: [android-developers] Re: create TextView

Np. There are many ways to get your desired behavior. I will post one of
them, just in case someone needs it. This is actually a toggle layout, so
it's a little bit more than what you asked.

cb.setOnClickListener(new OnClickListener()
{
TableLayouttl;


@Override
public void onClick(View v)
{
if (((CheckBox) v).isChecked())
{
if (tl == null)
{
Context c = v.getContext();

TableRow tr = new TableRow(c);
TextView b = new TextView(c);
tl = new TableLayout(c);
tl.removeView(tr);
b.setText("Dynamic test");
tr.addView(b);
tl.addView(tr);

LinearLayout parent = (LinearLayout) v.getParent();
parent.addView(tl);
}
}
else
{
LinearLayout parent = (LinearLayout) v.getParent();
parent.removeView(tl);
tl = null;
}
}
});

You would need to write your own Preference subclass for this, perhaps
by cloning CheckBoxPreference and altering its implementation.

I mean that none of the built-in classes (e.g., ScrollView) offer
scrollbars on the left side.

You are welcome to examine the 2,400 lines of code that make up
ScrollView.java and HorizontalScrollView.java to see if you can figure

[android-developers] popup menu on gmail

2010-03-27 Thread Eric

Hi,

I notice there is popup menu on gmail application once you click on
the left checkbox of each message item. If there is no message
checked, this menu would disappear.  What is that menu? How to
implement it?

Thanks,

-Eric

[android-developers] Re: Can an app upgrade itself?

2010-03-27 Thread Streets Of Boston

You can't 'automatically' upgrade your application. It always need
user approval.

When installing an APK, the user will be informed of the permissions
and he/she can decide to install or upgrade the application.

This is a good thing. If apps could automatically upgrade themselves,
without user consent/confirmation, that would be an enormous security
hole.

Re: [android-developers] Re: create TextView

A. create one time the container view then use setVisibility() to show or
hide it
or/and
B. you also have alert.getOwnerActivity() which gives you back the...
context :) you can then play around with it as you wish

[android-developers] Re: create TextView

So toggle the visibility from GONE to VISIBLE. I think this would be a quick
solution :)

Re: [android-developers] Re: create TextView

It's my pleasure to help :)

I think an easy solution is to use view.setVisibility(View.GONE)

Does this work for you?

[android-developers] Re: create TextView

 checkboxrifle.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Patient p = (Patient) spinner.getSelectedItem();
Service s = new Service("RIFLE");
if (((CheckBox) v).isChecked()) {
p.addService(s,0);
DataAccess.registerService(p,s);
//TableRow tr = new TableRow(this);
//TextView b = new TextView(this);
//tr.removeView(b);
//TableLayout tl =
(TableLayout)findViewById(R.id.dynatabel);
//tl.removeView(tr);

// b.setText("Dynamic tekst");
// tr.addView(b);
//tl.addView(tr);
} else {
p.removeService(0);
DataAccess.unregisterService(p, s);
}
}
});

1st of all tx for ur time.
So, i want to do this, push a checkbox, get an object in a spinner,
add a row to a tabel. Uncheck the checkbox and the row gets removed.
If i create textview outside the scope, i can add 1 new row to the
table. Second time i check the checkbox i get the error described
previously.
The removeView() just removes the view, the application does not
crash, but no new rows are added. It just removes the previously
created View and creates a new one.
If i can create the textview inside the scope the prob would be fixed
i think, just need something else then the 'this' when creatin a new
one.

Re: [android-developers] Re: create TextView

you should probably call removeView() :)) sorry, i could not help it :))

how about you just add the textview one time only?

or how about you just post your code?

[android-developers] Re: Filtered ListView with custom Adapter derived from ArrayAdapter is not updated

2010-03-27 Thread Thiago Diniz

Why do you want to put an edittext, listview already have an keystroke
filter.

I have a similar problem because my listview is not filtering, even
implementing the toString method os the class from my custom Adapter.
Ialso have a ListView with a custom Adapter that extends ArrayAdapter.
It's a ArrayAdapter of the Type User

[android-developers] Re: create TextView

Yeah, figured out that yet, if i do that it works if i push the button
1 time, the second time i push it the application just crashes.
Logcat gives me this error: You must call removeView() on the childs
parent first.
I need some way to 'flush' the textview.

Re: [android-developers] Re: In-App Purchasing and the Market Agreement

Yes I know. Warren brought that up. But the "game changer" was when I found
out that I can remove:

from the manifet.xml which hides the new app's from the user (hides the
clutter) and also doesn't allow the user to start it them on their own.

So then I can just keep the new "install apps" behind the scenes and they
don't clutter the users drawer. So there is not as much of an importance to
delete them right away.

What I might do is run checks for the install apps after a safe time (like a
week). Then prompt the user and ask them if they want to clean them up (i.e
remove them) letting them know that removing them DOES NOT remove the
character. This way in the long run they don't have a bunch stacked up
behind the scenes that they don't know about.

I do plan to make the character apps as small as I can and put as much of
the logic in the main app as I can.

So many little "details" we have to deal with...

Re: [android-developers] create TextView

Your code probably looks like this
AlertDialog a = builder.create();

a.setButton(AlertDialog.BUTTON_POSITIVE, "Ok", new OnClickListener()
{
 public void onClick(DialogInterface dialog, int which)
 {
  TextView b = new TextView(this);

   ...
}

You need to create the TextView outside the scope of the OnClickListener.
The "this" has to point to Context, which is your Activity.

Re: [android-developers] Re: In-App Purchasing and the Market Agreement

I am sure they will but I wouldn't hold my breath on WHEN. There was a
lengthy thread going about two weeks ago on here about improving the market.
I just skimmed it to follow along but they wanted to do a petition and
everything. I am not sure what happened to that. I would bet money that
google IS working on it. How could they not? Android is googles big thing
right now. But my thoughts are watching how long it's taken for Eclair 2.1
to come out I wouldn't count on  the Market being improved anytime quickly
which is why when a few people suggested that I hold off on doing my app
installs idea until they improve the market well... I don't really want to
wait til 2012 to put my app out.

[android-developers] ListView scrolls very very slow

2010-03-27 Thread jw

Hi all,

I'm kind of to android development. I'm creating an app containing
several activities, and one of them is an ListActivity. Each row
contains a ImageView (thumbnail) and two TextViews.

When the ListActivity is loaded everything looks fine, but when I
start to scroll it scrolls very slow. I've read some posts and threads
about this, and from what I understand the problem could be that the
UI thread is getting locked up when the getView() method is called in
my adapter class (extends ArrayAdapter).

The getView() is doing some, in this case, heavy processes. It looks
like this

@Override
public View getView(int position, View convertView, ViewGroup parent)
{
View v = convertView;
if (v == null) {
LayoutInflater vi =
(LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.row_item, null);
}
Item i = items.get(position);
if (i != null) {
name = (TextView) v.findViewById(R.id.item_name);
timeLeft = (TextView) v.findViewById(R.id.item_time_left);
thumb = (ImageView) v.findViewById(R.id.item_thumb);

name.setText(i.getShortDescription());
timeLeft.setText(Utils.getTimeLeft(i.getEndDate()));
try {

thumb.setImageBitmap(Utils.getBitmap(i.getThumbNailLink()));
} catch(Exception e){};
}
return v;
}

I've tried to speed up the getView() by using an DrawableManager class
that I found in this thread
http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview...
This gets the image (from url) in a seperate thread and handle some
simple cache for the images (HashMap). If I only add the image to the
row in the ListView it's pretty fast, especially due to the caching
done i DrawableManager. But when I fill the two TextViews with text it
still gets very slow. So that didn't help me out. (I also tried to
cache and handle the TextField values in the DrawableManager, but that
didn't help either.)

Do you guys have a good solution for me?

Thanks in advance

Like I said, I am not aware of any such limitation. As I wrote, the only
times I know of when alarms get nuked are:

-- on a reboot, all alarms go "poof!"

-- if the user has a so-called "task killer" app and kills your app that
way, your alarms go "poof!" (though alarms from other un-killed apps
remain in place)

Conversely, there are places in Android itself where AlarmManager is
used from an Activity -- alarm clock and calendar, to name two.

Then maybe it's the Service that is dependent? All I know is it works
after reboot, but not after immediately installing (and starting Alarm
from Activity). It's a 1 hour+ timer.

AFAIK, AlarmManager alarms are not dependent upon the particular

It just occurred to me that if I create it from a static context it
shouldn't really die with the Activity. That's what I used to be
doing, but later I switched it to an instantiated class. I'll see what
happens.

[android-developers] Re: No Network Connectivity in Service/AlarmManager Process.

2010-03-27 Thread AuxOne

I'm starting the AlarmManager from a BOOT_RECEIVED broadcast and it
works like a charm. I've noticed, however, that it requires a restart
to take effect because it's triggered from a broadcast. In light of
this I also start the AlarmManager from the onCreate() of my activity
so that the user doesn't have to restart their phones, in this case it
doesn't really work.

I've read that Alarms/Services set from the Activity are destroyed
when the Activity is. Is there some way around this? Perhaps have the
Activity bounce a Broadcast off something such that the Service is not
directly created from the Activity and thus doesn't get destroyed?

Thanks

[android-developers] Gallery android:unselectedAlpha works strangely

2010-03-27 Thread arnouf

Hi all,

I work with a gallery and a BaseAdapter.
In my XML file I specified, on my gallery, android:unselectedAlpha.
When I select an item (using click or pad) image are moved but they
take the alpha defined for (normally) the unselected image.

Do you have any idea ?

[android-developers] Can an app upgrade itself?

2010-03-27 Thread A R

Hello Everyone,

 Is it possible for an app to upgrade itself?

 I am trying it but it doesnt seem to work. My app downloads its
upgrade, starts the upgrade/installation process which finishes
successfully but when I start the app its still the old one.

 When I installed my app normally I was seeing  "Not granting
permission android.permission.INSTALL_PACKAGES to package "  in logs.

 So based on another thread
http://groups.google.com/group/android-developers/browse_thread/thread/23a94989d964d7fd
I installed the app in /system/app folder so now there is no error
message but result is still same.

 Do I need a separate installer app to upgrade my app?

Kindly advice.

Regards,
Amit.

Neither. Your application will crash.

You cannot modify the widget-based UI from a background thread.

Now, I cannot speak for 2D (Canvas) or 3D (OpenGL) apps and what their
limitations are vis a vis threads. I am only talking about using Views.

Thanks Dianne. What about if your app has multiple potential Root
Activities and so you cannot be sure (from the Notification) which one
it is?

[android-developers] Re: Timer / threads / reliability

2010-03-27 Thread Neilz

Ok, reviving an older thread.

Is there a way, to have View elements (TextView, Button, whatever)
that are not run on the main UI thread?

What about if I set up a game thread, with its own View (like in the
LunarLander sample, for instance) and then create View elements on the
fly and attach them to the main View? Are these still going to be run
in the main UI thread, or in the game thread?

Thanks.

[android-developers] Re: In-App Purchasing and the Market Agreement

Thanks. But it slipped my mind as I was writing it that immediately
deleting the new app is going to be a loser, because it'll refund your
payment.

You'll have to arrange to do that at another time. Or not, and live
with the clutter. Or simply use your .apk as the storage for your
characters. That may actually be reasonably space-efficient, unless
the character data is pretty small.

It's not an issue for free/paid, because it's the older, free one
that's being deleted in that case.

But perhaps some components of my idea may be useful, or the code
snippets.

A really BAD idea would be to use the AlarmManager to initiate the
deletion sequence. In fact, MOST uses of the AlarmManager to launch UI
are bad, but this would be particularly evil.

I'd do well as a prank app author, if I didn't have a conscience!
