Re: [android-developers] Re: searching in HUGE SQLite database

[Frank Weiss]

As I recall, there were no indexes on the table. Without indexes I would
expect most every query on a very table to be very slow.

[android-developers] Re: Test case throws permission exception

[Diego Torres Milano]

You have to set the permission on the application's manifest not on
the tests' manifest.
That's what you usually do by having a main and a tests project.
Furthermore, your test should look more like:

public class AndroidDummyContactsTests extends InstrumentationTestCase
{

private static final String TESTUSER_NAME = "Test User";
private static final String TESTUSER_NUMBER = "1234568909";
private Instrumentation mInstrumentation;
private ContentResolver mContentResolver;

public AndroidDummyContactsTests(String name) {
setName(name);
}

protected void setUp() throws Exception {
super.setUp();
mInstrumentation = getInstrumentation();
mContentResolver =
mInstrumentation.getTargetContext().getContentResolver();
}

protected void tearDown() throws Exception {
super.tearDown();
}

public final void testInsertContact() {
final ContentValues values = new ContentValues();
final Uri rawContact =
mContentResolver.insert(ContactsContract.RawContacts.CONTENT_URI,
values);
assertNotNull(rawContact);
final long rawContactId = ContentUris.parseId(rawContact);
assertTrue(rawContactId > 0);

values.clear();
values.put(Data.RAW_CONTACT_ID, rawContactId);
values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);
values.put(StructuredName.DISPLAY_NAME, TESTUSER_NAME);
assertNotNull(mContentResolver.insert(Data.CONTENT_URI, 
values));

values.clear();
values.put(Data.RAW_CONTACT_ID, rawContactId);
values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
values.put(Phone.NUMBER, TESTUSER_NUMBER);
assertNotNull(mContentResolver.insert(Data.CONTENT_URI, 
values));
}
}

and it works (remember that you need an app too where you grant the
permission), but as you are not using mock objects you will be
populating your contacts database with test data which is probably not
a very good idea.

You have a getView() method where you build these custom items, I assume.
You could set the Tag property on each button with the index it's for, then
when you click the button just pull it out and use that to index.

[android-developers] Re: searching in HUGE SQLite database

[Menion]

Hi guys
 thanks for your big help!

so after I read all answers there is only one solution for me! Deny
users to have database bigger then 2GB!

why?
  because structure of database cannot be change. It's something like
"standart" so I have to use it as is! I just wanted to know, if exist
any SQL query, that help me to get some data with slower speed but
without crash. Nevermind, I just, when find this big database on
filesystem, I'll "Toast" user message that this is not allowed!

thank you very much!

[android-developers] Installation error: INSTALL_FAILED_SHARED_USER_INCOMPATIBLE

[Luxi]

Hi,

In my application's AndroidManifest.xml, i added
android:sharedUserId="android.uid.phone". But when I adb install,
Eclipse's console gave me this error. I  searched in the website and
found some ways to re-sign my apk, for example, using signapk.jar,
platform.x509, platform.pk8 to re-sign. But no matter how I do, it
still has this problem.

any ideas?

[android-developers] how to remove an item from a listView and arrayAdapter

[gonzobrains]

Hi,

I have a collection of items in an ArrayList.  I add them to a
customer adapter as follows:

this.m_adapter = new MyAdapter(this, R.layout.myitem,
itemCart.m_items);

I have a delete button for each of these items in my list, but I am
not sure how to connect the delete button's onClick() with the
original item in the ArrayList.  Can someone please explain how to do
this or point me to a tutorial where I can read up on this?  Non-
sarcastic/non-condescending responses are greatly appreciated.

Thanks,
gb

How about the entire Wendy's 99 cent menu, if you live in America?  Or
anything in "dollar stores" around the US?

Maybe it's an American thing, not that I'm particularly proud of that!

You must not have created a somewhat deeply nested view hierarchy yet,
nor have you tried to reuse parts of one hierarchy in another.  Nor
have you tried to maintain said hierarchy over a long stretch of time.

Or you must really like java and despise xml!

[android-developers] Re: How best to query web repeatedly.

[Spiral123]

Well50 mph is about 22 m/s - so driving at that speed in a
straight line you are firing web queries off at the rate of
approximately 1 every 2 seconds.  Running sql queries over the web on
a 3G network I'm not really surprised that the app locks up and has
lag.

Why not write a little app to fire off one of your queries every 60
seconds or so and record the round trip time for one of your typical
queries.  Then go and drive around in different locations and at
different speeds and see what sort of real life response you get?  My
guess would be that the critical point is not your app but the
network.

You could also try writing an app that just writes a timestamp every
50 meters and drive around to see how frequently your queries are
going to be run.

[android-developers] How best to query web repeatedly.

[cellurl]

I run GPS, and query a web based mysql every 50 meters of driving.
People tell me the app locks up and has lag, so I put each query in a
new thread. This seems to create a backlog of threads (at least in the
emulator).

URL url = new URL("http://www.website.org/marks.php";);

HttpURLConnection urlConn = (HttpURLConnection) url
.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
urlConn.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
response.append( inputLine );

1. Are dozens of threads wrong? Do I just use two and leave it at
that?
2. Should I keep connection open as I have heard others speak of?
3. Will I ultimately be forced to sqlite and the new headache of db
synchronization?

Anyone have any experience to offer?

Thanks in advance,
-cellurl

[android-developers] Re: Detect if app is installed

[Brill Pappin]

Ok, this is what I want you to try.

1) don't use the http:// for you content URL. it should be something
related to your app.
2) for your link, link to a real web page that simply has a "Launching
app..." on it.
3) when that page loads, use a javascript call to try and launch your
application and display a market link if it gets an error.

I'm not positive this will work, because I haven't researched how the
browser does it's URL linking (i.e. would it work from an ajax call?).

There are several ways you can have the browser diaplay something more
interesting than a error page, however you may need to play with it
(no, i'm not going to do that for you).
For instance you might need to change the browsers location to
activate the content URL... which might not work with ajax... in that
case an arrangement of frames might work, so that one frame can direct
the browser to the content url and if it detects an error, show
something useful like the market link.

I guess what I'm saying is stop arguing about it and actually try
something :)
If you solve the problem, post the solution and make everyone eat
their words!

[android-developers] Re: Detect if app is installed

[Brill Pappin]

Actually, I understand what hes trying to do.
He wants to launch *his* application from a link in an html page or
detect if its not there.

What he's saying is that hes registered a content URL http://com.hisappname
but if the app doesn't exist he gets a terrible error in the native
browser because the browser thinks it's looking for a website that it
can't contact.

He's got a few problem... the first one would be hijacking the http://
but this is still workable.

Right and she's saying it *should* be. So if there's no app, it still works
to go somewhere on your site (perhaps redirecting them to the Android
Market). If there is an app, you code your app to handle that specific URL
and respond to it.

I am not sure I follow you with "your link should be to a web page on

actually a real Web page link. Yes, I reuse http schema but
com.mycompany.myapp is not a site, it is the host that my app activity
registers to handle.

[android-developers] Re: searching in HUGE SQLite database

[DanH]

It won't do any good to break the table into smaller tables in the
same database.  SQLite throws all the tables into one large pool that
it manages as a single "heap", so you still get offsets as large as
the overall database size.

You'd have to put the different tables into different database files.

[android-developers] Eclipse 3.5.2 is suddenly throwing a NPE while "Initializing Java Tooling"

[OldSkoolMark]

Eclipse is suddenly very unhappy. A project and workspace I've been
using without incident for weeks is suddenly throwing an NPE during
Eclipse initialization. The package hierarchy window doesn't appear,
and the effect of most commands is to generate errors and
corresponding log messages.

Here's the log file. This entry is actually repeated many times. I'm
wondering if switching to Helix might clear this issue. Any other
suggestions?

[android-developers] No update notification when app-title changed

[Marcus]

Hello,

I have an android app on the market for some time (7 month) that was
labeled as "Beta" in the title. Yesterday I published a new version
and thought it's time to leave the beta state. Therefore I switched
the app-title in the market backend and removed the "beta" tag.

The problem is: now, the users don't receive any update notification!
If you search for the app in the market, the red update label is shown
correctly. But in the "my apps" section, the update label and the
notification is never shown. The user doesn't see that there's an
update.

It didn't work on my two phones (both 2.2, I cleared the market cache)
and it seems like, nearly all users continue to use the old version.

So, is this a known problem? Or was it just a temporary problem on my
phone? Can anybody confirm this behaviour?

And, what can I do now? Switching the title back doesn't seem to help.

Thanks a lot

Marcus

[android-developers] Galaxy S blocked

[Diego N.]

Guys,

My nephew was trying to unlock my Galaxy S where is the standard type and ended
upblocking everything.

Now my login is being requested for a Google account, I put it and nothing
happens. I searched the net and saw many people talking to put "null" in the
password, but to no avail.

Has anyone experienced this at the Galaxy S?

Att,

[android-developers] Re: searching in HUGE SQLite database

[asierra01]

  What you have is a database/dba issue not an android issue

  Lets say you have 1 database ( may be with 1 table 8G in size)
  BRAKE the database in
  1 Table that will hold some kind description (metadata) of what the
BIG01, BIG02, BIG03, BIG04 tables have
 BIG1, BIG2, BIG3...,BIG99 will have at most 100K records , lets
say and will potentially be as big as 100MB? 300M ? in size or less
 This table will have three fields (first_rec_key, last_rec_key,
table name)
 Table1->
  (0, 5,'BIG1')
  (51, 100, 'BIG2')
  (101, 40, 'BIG3')
  
  (80, 900, 'BIG78')
you start by looking in this table that only has 100 records
   it will tell you the key you need is in BIG56, which is 100M,
   now you use your current method of finding your record, just
instead of looking on 2GB table
   you look into 100M or 300M BIG56 table.

That should be the default behavior. Unless you're running immediately low
on memory and your app is being killed. Use your debugger and some logging
to determine what happens to your app when you press Home.

You can't just sign any app with the platform key. AFAIK, you have to build
your app along with the whole platform.

Even if the user's app is not running, it will be an option to launch the
intent. If it's not, it's because the OP himself has not set up his filters
correctly or the user has already explicitly set the browser to handle it by
default, which means they were presented with the option at some point.

If you have a default or only one thing to handle the intent, that gets
used. If you have multiple options and no default, you get a choice. If you
install a new app that can handle the intent, the default is cleared. Also,
on my Nexus, the default seems to be cleared on a reboot. Not sure if that's
a bug.

[android-developers] Re: Anyone know how to calculate speed WITHOUT GPS?

[Indicator Veritatis]

This code shows us how to get the accelerometer data from the
SensorManager, but not how to calculate the velocity correctly. The
naive formula you use is correct ONLY for a completely noiseless
signal. But all signals in the real world DO have noise, which must be
filtered out.

Filtering it out for an accelerometer is tricky because integration
already IS a low pass filter, so by simply integrating, you are
throwing away the data you need to separate signal and noise.

Google "accelerometer filter" for the variety of different approaches
that have been tried.

I think I got this the wrong way around.  The Tab has a higher value,
which is what you would expect for a tablet rather than a phone.

Two things; I have maps where I might need to show an actual "miles
per inch"-equivalent scale, though I now think that's impossible, and
also to select things like font sizes.  I appreciate that the
quantised density values are appropriate for the latter, though it is
slightly complicated by the fact that I also support iOS devices whose
density values don't align with your choice of quantisation; if I get
an Android device whose screen has the same dimensions as an iPad, I'd
rather use the iPad graphics that I already have.  So I'd like to
quantise the actual density to a slightly different set of values than
the ones you've chosen.

[android-developers] Re: Anyone know how to calculate speed WITHOUT GPS?

[Indicator Veritatis]

This code shows us how to get accelerometer readings out of the
SensorManager, but the calculation you perform neglects noise in the
accelerometer output. So if you actually try this out, you will notice
it will not compare well with the car's speedometer.

As I mentioned before: to get a realistic solution, you need to
account for the noise by viewing integration as a low pass filter

Sounds like your views are being recycled and you're not handling it

Google "adapter view recycling" or something - you should get lots of info.

Maybe this:

int, java.lang.String, java.lang.String)

From a 2 second gleam of the docs.

[android-developers] Re: Code Assist still Slow

[snpe]

https://bugs.eclipse.org/bugs/show_bug.cgi?id=329288 contains patch
that fixes this issue.
Unfortunately patch is applied only in 3.7 branch.
I have patched org.eclipse.jdt.core from Helios 3.6.1 with the patch
attached in this bug and create a patched plugin.
You can replace your /plugins/
org.eclipse.jdt.core_3.6.1.v_A68_R36x.jar plugin with one from
http://adt-addons.googlecode.com/svn/patches/org.eclipse.jdt.core_3.6.1.v_A68_R36x.zip
and restart Eclipse. Content Assists will be much better. Just try it.
Don't forget backup your original plugins.

[android-developers] Re: Anyone know how to calculate speed WITHOUT GPS?

[Indicator Veritatis]

No, because as already pointed out, a naive integration of
acceleration is too inaccurate; it is too easily corrupted by noise.

Now you can improve it somewhat by considering integration as a low
pass filter, and applying DSP techniques to enhance the accuracy, but
don't expect a dramatic improvement in accuracy. Especially if the
phone has ever been dropped:(

A better solution might be to do the above DSP, but also check it
against the GPS results whenever they ARE available. But this is
complicated.

[android-developers] Re: Detect if app is installed

[Indicator Veritatis]

Well, I am afraid a lot of us are 'missing something here". But
frankly, that is because the OP does not express himself very well. So
no wonder he gets some telling him it is impossible, others telling
him how to do something somewhat different from what he wants.

But be that as it may, I believe the reason he will not considers
yours a solution is that if his application is installed but not
running, or if for any reason it is not registered to handle the
Intent, then no, it will not "catch that URI" when the users browses
to that link using the phone's HTTP browser (whether that is Google's,
Dolphin's or whatever).

Or perhaps he does not trust the built in browser to let his
application handle the Intent first: it always has been a little
mysterious to a lot of us that sometimes, we click on a link and it
immediately uses the current browser, but sometimes we get the pop-up
asking us which application to use on that link.

Re: [android-developers] Re: searching in HUGE SQLite database

[Dianne Hackborn]

Yeah it's actually very likely the problem.  Android for various reasons
defines off_t to be 32 bit, so if you want to support > 2GB files you need
to use off64_t.  That unfortunately makes it easy to have code paths that
break like this.

Re: [android-developers] Re: Detect if app is installed

[Dianne Hackborn]

Maybe I am missing something here, but your link should be to a web page on
your site that actually exists.  If the user arrives there, they don't have
their app installed on their device (or aren't on an Android device at all),
so you can tell them they need to install the app and have a link to Market.
 If the app already is on the device, then it is catching that URI so they
get the option to launch it.

Fwiw, this is essentially how things like YouTube and maps works, except of
course they are *often* pre-installed on devices (but not always), and the
"fallback" web page is actually their full web site.

There is also another Google service that does the full flow you are talking
about, though for the life of me I can't recall what it is.

time to identify views, so it's definitely possible.

I've tried android:tag which does not seem to be able to do it in this

The situation is that I have a single java class extending view.
I inflate one of many XMLs into the view and I need to be able to 
change stylesheets based upon which xml resource i'm loading.


Does anyway one a method of doing this?

My last fallback is to use some sort of static class that I can set 
the xml resource on for the entire app, then try and look at the id to 
determine which resource I loaded. I'm reluctant to do that because 
it's kludgy and I think its far more likely to introduce bug etc. Note 
that I haven't tried to do this yet, but it should work based on how 
java behaves.


I just can't believe that there is no way to a view to know what XML 
resource it was inflated from!

Re: [android-developers] Calling onUpdate() from onReceive() in AppWidgetProvider

[Kostya Vasilyev]

sendBroadcast is not how you update a widget on demand (I.e. in response to
some data or state change).

I just posted a code example of this, check recent messages, the original
question referenced Power Controls.

[Diego Torres Milano]

If you want to provide a different behavior for the test runner just
create your own extending it:

public class MyTestRunner extends
android.test.InstrumentationTestRunner {

}

To do whatever you want, use android.test.InstrumentationTestRunner
source as a an inspiration.

[android-developers] Re: Amazon to Policy Android Market Place

[blindfold]

Same answer as in 
http://groups.google.com/group/android-discuss/msg/b71caf66580b9cd0:

Good point. Not currently, but this I can (and will) easily fix by
checking if the Android Market app is installed, in the same way that
I check if ZXing is installed. However, doing so will AFAIK still not
suffice to comply with the Amazon Appstore requirements, because my
app would still perform a search on Android Market if the Android
Market app is installed and ZXing isn't. If Amazon only wants graceful
degradation in cases where users do not have the Android Market
installed, that is fine with me, and I'll gladly comply with that.

[android-developers] Re: Amazon to Policy Android Market Place

[Streets Of Boston]

If your app can be installed from another market than the Android
Market, you cannot assume that the "market:" intent/scheme is handled
on every device.

If users without Android Market on their device download your app from
Amazon Market, how would your app react if fails to find ZXing (i.e.
if it fails the "market:" intent)? If your app fails gracefully and
your app is still (fully) functional, Amazon shouldn't complain. But
if your app just raises an error and, for example, quits your app,
Amazon has a point of rejecting your app.

If your app handles a lack of the "market:" scheme/intent gracefully
but Amazon just tried it on a phone *with* Android Market installed
and didn't like the fact that the Android Market activity was started,
then I think Amazon is wrong. They can require apps to handle missing
functionality gracefully, but they should not forbid any searches
using the Android Market if Android Market is installed.

[android-developers] Re: Simple compass functionality

[Phil Endecott]

It seems that Display.getOrientation() probably returns the same
constants as the new Display.getRotation(), i.e. Surface.ROTATION_n,
and that it *does* potentially return all 4 values.  Good.  It's
unfortunate that this information was removed from the docs when
getOrientation() was deprecated: could it be re-instated?  I now
cannot understand why Google Maps gets its compass pointer wrong half
the time, but I'm glad I discovered that now, rather than while
actually trying to use it for navigation!

Re: [android-developers] Re: Simple compass functionality

[Kostya Vasilyev]

This is an artifact of a continously evolving platform.

I'd say, use Java reflection to access the new methods that give you new
orientation values, and fall back on the deprecated method if running on
older platforms.

Reverse Landscape was only introduced in API level 8, so the earlier
platforms don't have this notion yet.

IMO, it's ok to use a deprecated method like this - after all, documenting
an API as obsolete because there is a newer API in the newer platform
doesn't change anything on devices with older firmware that are already out
there, or in the applications written for earlier platform versions.

The intent is to say "don't use this if you can use the newer API", but for
older platforms, there isn't anything else but the old API, so go ahead and
use it as a fallback.

Re: [android-developers] Power Control Widget shown when my own Widget is updated by AppWidgetManager

[Kostya Vasilyev]

I went an looked at the code (TreKing is right about the image though - if
you post an image link, make sure it's accessible by anyone).

Your bug is here:

AppWidgetManager appWidgetManager =
AppWidgetManager.getInstance(getApplicationContext());
ComponentName componentName = new ComponentName(getApplicationContext(),
Widget.class);
int[] ids = appWidgetManager.getAppWidgetIds(componentName);
Intent update_widget = new Intent();
update_widget.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, ids);
update_widget.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
getApplicationContext().sendBroadcast(update_widget);

What this code does is sends an update broadcast to all receivers (== all
widgets) that exist in the system at this time, but using your own set of
widget ids.

Widget ids are not unique to your application, they are assigned globally.
When other widgets see this event, they "think" that the home screen
application is asking them to update their views - in screen cells idetified
by *your* widgets. And that is what you are seeing.

To update your widgets "on demand" - as opposed to from onUpdate - do this:

AppWidgetManager manager = AppWidgetManager.getInstance(context);
ComponentName thisWidget = new ComponentName(context, YourWidget.class);
int[] widgetIds = manager.getAppWidgetIds(thisWidget);

for (int widgetId : widgetIds) {
 RemoteViews updateViews = ;
  manager.updateAppWidget(widgetId, updateViews);
}

or

manager.updateAppWidget(thisWidget, updateViews)

if all your widgets have the same visual state at any given time.

You can run this code from anywhere within your application, such as a
BroadcastReceiver that handles clicks on your widget (probably more fitting
than starting an activity without a content view, which immediately
finishes).

Actually, you can handle the PendingIntent for clicks in your
AppWidgetProvider, since it's a subclass of BroadcastReceiver.

I can understand where you're coming from.

What would work for me as a user is a simple close box next to this

Re: [android-developers] Widget - NO API to find out Widget is in Foreground or Background. Any other Alternative API's to achieve this Functionality

[Kostya Vasilyev]

Sam,

There is no "background" or "foreground" state for home screen widgets since
they are never allowed to overlap.

If you would like to perform an expensive (CPU or battery-wise) continuous
update, and looking for a way to optimize by checking for home screen
visibility - well, this might not be a good idea, as that's not really what
home screen widgets are for.

Correct. Which is why this is where you display the generic market URL, even
if they're on their phones and have you app installed (which you can't know,
as we've established).

It is trivial - if the application you're are trying to detect runs in the
same environment in which the user is running. In your example the Flash app
runs in the browser, which is where the Flash plug-in will be. In Android
it's fairly trivial to detect if another app is installed. However, trying
to dynamically discover what may or may not be running in a completely
different, unrelated environment without any "hooks" on both ends is not so
trivial.

I just submitted information on the Android JavaDoc issue here for Eclipse:

The same JavaDoc package, "Documentation for Android SDK", worked without a

[android-developers] Re: Detect if app is installed

[ls02]

User may land on my Web page in external Web browser in which case I
have no control to inject any code from the app.

Say you have a Web page that uses Flash. Do you want to mesage to your
customers link to install Flash EVERY SINGLE TIME they visit your page
instead of trying to dynamically discover if Flash is installed and
directing customers to install Flash ONLY if it is not installed?
Sounds trivial.

As I said, if your user has your app installed, you can control the Webview,
which includes which pages you show them, which allows you to not show them
the page that links them back to the market, if the thought of doing so is
so offensive to you.

[android-developers] Re: Amazon to Policy Android Market Place

[blindfold]

My app got rejected by Amazon Appstore today because it searches for a
third-party app (the well-known free ZXing barcode reader) on Android
Market if the user tries to launch it from my app and it is not
installed. The barcode reader acts as a functional extension to my
app, launched via an intent, and I would not even know if it will come
to Amazon Appstore. So I'm not pleased with the Amazon Appstore
restrictions, and do not know of an elegant way to deal with this use
case. There is a related and ongoing discussion in the android-discuss
thread "Amazon Market - First red flag"

[android-developers] Re: Code Assist still Slow

[snpe]

Kostya,

IMO, there isn't bug in Eclipse for the problem related with Javadoc
attachment. I can reproduce them when using javadoc from master AOSP
(I have trying CA for TextView.setText()).
It's possible that it isn't correct Javadoc, but it's bug in Helios
still - Helios doesn't handle correctly missing Javadoc.
For instance, if some method doesn't have Javadoc, Helious search
Javadoc contents for this method over and over again.
I suppose that we have create a new Eclipse bug.

Peco

PS
I have created https://review.source.android.com/#change,20460 that
enables removing Javadoc in Android classpath container.

You should probably elaborate on what errors you're getting. Describe in
detail what you're seeing on the emulator, maybe with some pretty pictures
to assist.

Re: [android-developers] Re: Code Assist still Slow

[Kostya Vasilyev]

Have you tried code-assisting a view reference?

I did the "sources" thing, and didn't have to disable JAX-WS because I don't
have it, but bringing up methods of a view was still slow.

Removing Docs did fix it completely.

Thanks. This of course begs the questions of why you have to go through your
website to "do very cool stuff" and not just within the app itself.

Ultimately, this doesn't seem possible. My suggestion would be, as has been
said, a market link on your site to get your app. Then in your app you
include a WebView where you can explicitly control access to your site. Then
you know your app is installed and can do "very cool stuff" through
javascript bindings or something.

[android-developers] Re: Detect if app is installed

[Brill Pappin]

Ok, that is a much better explanation.

You can control the error your site displays to the user through your
web server.
However the error you mention looks like it comes from the client
browser anyway.
I'm sure with a little thought you can use come ajax trickery to make
this look better and give the user your market link instead.
It doesn't sound like anyone (who has answered you) is doing this, so
your going to have to invent the solution for yourself.

[android-developers] Re: Detect if app is installed

[Brill Pappin]

I think we've pretty much said we don't think it is.

I for one don't know of any way you can do that, and if you can, I
think it's a *very* large security hole in the Android OS that I'll
submit a ticket to get fixed ASAP.

[android-developers] Re: Detect if app is installed

[Brill Pappin]

Are you able to launch your app if its not installed now?
If you can launch an intent (which I hipe you can't) then take a look
at the zxing project. They use code so that if you try to launch with
their intent and its not installed, it prompts the user to install it.

However my guess is that is not going to work for you, because it
requires some code.
As someone else mentioned, give the user a market link.
