[android-developers] Re: google analytics jar and notifying my app users

[Brill Pappin]

Haha.
I don't think thats in the spirit of the notice, but i grok why you
put it there... I would likely do that as well :)

I've been thinking about adding it to my keyboard simply as a way to
get some demographics on what kinds of devices the users are using my
software on.
I want to make some changes, but I need to know who my greatest user
base is so I can keep them happy.

I'm glad to know that you've decided for me the device I'd be most
happy with, given that you don't really know anything about me, how I

at least you've decided for me.

Sorry, I need more information.

You're saying that because I had the phone connected to my computer
with the USB cable (so I could deploy the application to the device),
that means that the SD card in the phone is mounted on the WinXP box,
and so can't be used from the phone?  Is there something that should
be done in the setup of the test on the phone so that I would unmount
the SD card from the WinXP box, but still let me step through the code
while it's running on the phone?

Calling Environment.getExternalStorageState() will tell me the
"current state" of the SD card.  How does that help me?

[android-developers] Re: Anybody seen a slowdown in sales?

[Doug]

FWIW.  My relatively popular app's sales have been roughly 20-30%
lower than average over the past 30 days compared to the previous 30
days.  Also, my app has jumped up a few slots since I last checked it
a couple weeks ago (and the category as a whole seems fairly shaken
up).  I haven't updated my app in the past month.  Also, my install %
has been dropping (again) since the last time Google found that stat
to be incorrectly dropping.  It's like they patched it, but then it
went back on its merry way down.

Honestly, after obsessing over these things for over year, I have
finally just let it be the way it is and have found more interesting
things to obsess over!

[android-developers] Encoding/decoding problem

[Eric Kraft]

Just a quick suggestion for you due to limited information about your 
situation: check the byte ordering of your TCP request. One machine might send 
data big-endian and the other might receive it little-endian. The fact saving 
the byte stream to a file works makes me think this is the issue you are having.

[android-developers] Re: Encoding/decoding problem

[DanH]

Any time you transfer data (anything more than simple ASCII) over the
net you need to be aware of data conversion issues.  It's a
complicated issue, and depends on which specific protocols you're
using, what computer languages are involved, how you describe the
data, etc.  It's a topic for a book, not a post.

If you were to describe specifically how you're transferring the data
then maybe someone could help you with this specific instance.

[android-developers] Re: SQLite Encryption

[DanH]

The problem with SQLCipher, of course, is that you need to compile the
whole C SQLite implementation and embed it in the phone as native
code.  Doable, but not for the faint of heart.

But it is certainly the most secure and complete approach to data
encryption on a phone.

[android-developers] Cursor Adapter for Contacts

[Kavinder Dhaliwal]

I'm trying to get an autocompleteTextView with a custom cursor adapter
to allow a user to search his contacts and begin returning suggestions
from the first letter.  My problem i that the way i've implemented it
now, which is the only way I have found to return name and phone
numbers from the current API only returns one contact thoughso if
i search "r" it returns only one contact beginning with r until i
actually spell out a specific name

Code:

 Cursor idCursor =mContent.query(uri, null, null, null, null);
String id = null;

while(idCursor.moveToNext())
{
int idIdx =
idCursor.getColumnIndexOrThrow(ContactsContract.Contacts._ID);
id = idCursor.getString(idIdx);
Log.i(TAG, "idCursor count = " +idCursor.getCount());
Log.i(TAG, "ID"+ id);

}
idCursor.close();

 if(id != null)
{

String where = ContactsContract.Data.CONTACT_ID + " = " 
+ id
+ " AND " +ContactsContract.Data.MIMETYPE + " = '" +

ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE
+ "'";

Cursor dataCursor =
mContent.query(ContactsContract.Data.CONTENT_URI, null, where, null,
null);
int nameIdx =
dataCursor.getColumnIndexOrThrow(ContactsContract.Data.DISPLAY_NAME);
Log.i(TAG, "NameIdx " + nameIdx);
int phoneIdx =
dataCursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER) 
;
Log.i(TAG, "PhoneIdx " +phoneIdx);
int typeIdx =
dataCursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.TYPE);
Log.i(TAG, "typeIDx = " +typeIdx);
String[] result = new String[dataCursor.getCount()];
Log.i(TAG, "DataCursor = " +dataCursor.getCount());
if (dataCursor.moveToFirst())
do { // Extract the name.
String name = dataCursor.getString(nameIdx);
// Extract the phone number.
String number = dataCursor.getString(phoneIdx);
Log.i(TAG, "Number = " +number);
result[dataCursor.getPosition()] = name + " (" 
+ number +
")"; } while(dataCursor.moveToNext());


return dataCursor;

}


Clearly the reason I can only get one name is obviously because I pass
the id from my first query.So basically I am looking for the same
the effect as I have now that can match its query to multiple contact
ids

Any help?

[android-developers] Re: SharedPreferences not persisting

[neuromit]

So I have log messages that get displayed whenever onPause, onStop,
and onDestroy get called.

I don't actually save my preferences in any of these methods, I save
them when the values get changed by the user.

By watching the logcat messages I have determined that my preferences
get deleted (do not persist) only when the onDestroy()  method is
called but when onStop is called the preferences load perfectly fine
the next time my activity starts.

Re: [android-developers] already created always-on-top-of-all-windows view, how to add touch functionality?

The whole point of that window type is the window can't get any user input.

This is not stuff that third party applications are supposed to do.  I
strongly discourage this -- whatever you do here is likely to break in

Re: [android-developers] Re: Dynamically reading drawable file names

[Dianne Hackborn]

I don't know what to say, the code I pointed to is exactly what has been in
the platform fairly unchanged since 1.0 and has worked fine.

Are you sure you are doing this on a Context that is actually for your
application?  The error message ("Invalid package identifier") indicates it
doesn't know *anything* about your application.

Also I wasn't pointing this code as something to directly copy and paste,
but as a guide.  It comes from really deep down in the framework, so it is
not written as normal application code.

In fact if you copy and pasted the Resources.getSystem() part, that would be
your problem, because that is an API one doesn't normally use to get the
system-only resources.  You should use the normal Resources object in your
app.  (That's why the link I provided went directly to just the line pulling
out the resource data.)

[android-developers] Re: google analytics jar and notifying my app users

[Nathan]

All good ideas.

I have a help screen that shows when starting the app. At the bottom,
it has a license agreement. Among other things, it says "This software
gets anonymous usage statistics through Google Analytics."

The license agreement is a good place. No one reads it anyway.

[android-developers] Re: Anybody seen a slowdown in sales?

[Zsolt Vasvari]

Another thing I've noticed, is that my purchases from the UK have
stopped in the last 5 days.

Before that I've average 1 1/2 sales a day from the UK in the prior 30
days, representing about 6% of my total sales, but there has been 0
since Dec 14.

[android-developers] already created always-on-top-of-all-windows view, how to add touch functionality?

[Aco]

Hi All! I'm trying to create an always-op-top button/clickable-image
which stays on top of all the windows all the time. The proof of
concept is here 
http://www.appbrain.com/app/smart-taskbar-%28sidebar%29/com.smart.taskbar
and here http://forum.xda-developers.com/showthread.php?t=865525 I'm
following this example code
http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=services/java/com/android/server/LoadAverageService.java;h=0d86429aaa5ccf6ecf311dfb3af0f3ccbf5f8d29;hb=HEAD

I have been successful and have a running service now. The service
displays some text on top left corner of screen all the time while
user can freely interact with rest of apps in normal manner. What I'm
doing is subclass ViewGroup and add it to root window manager with
flag TYPE_SYSTEM_OVERLAY. Now I want to add a button/clickable-image
in place of this text which can receive touch events on itself. I
tried overriding "onTouchEvent" for the whole ViewGroup but it does
not receive any event. How can I receive events only on certain parts
of my always-on-top view group? Kindly suggest.

There is generally little if any official help here regarding the Maps API

This was just an example that fit the example you provided. I trimmed

The same thing happens at the same line.

I get a warning first:

AFAIK, "sticky" means the system will try to restart the Service if it was

Yes, you can start a service in response to system events, however, I stress

Re: [android-developers] Re: start a new activity and then... come back to the old one!

[Dianne Hackborn]

clearTaskOnLaunch means that your entire task will be reset when the user
re-launches it from home (like the settings app does), so if that isn't
happening regardless of whether you are currently in an e-mail activity that
is a bigger problem.l

Am I to assume from your attributes here that this activity is a "front
dore" activity that doesn't display or do anything, but just launches the
"real" activity of your app?  If not, using finishOnTaskLaunch and noHistory
is really questionable.  If it is, consider making this one the NoDisplay
theme (and then don't worry about setting a forced orientation on it since
it will never be seen).

[android-developers] Re: How to simulate a (missing) DPAD

[blindfold]

OK, I've got it working, and in a rather straightforward manner.
Although dispatchKeyEvent() for some reason does not always determine
which UI element gets focus, it turned out that the UI element
actually does have a focus that one can in onKeyDown() reliably
perform a hasFocus() for after having done setFocusable(),
setFocusableInTouchMode() on all UI elements and a requestFocus(),
requestFocusFromTouch() on one element. Next, after putting all UI
elements like radiobuttons, checkboxes and editboxes in (for instance)
arrays, one can assign focus to the previous or next element when the
volume up or down key is pressed, thus hard-coding in what order UI
elements are traversed. Not very elegant, but thus far it works
reliably (no strange dependencies on whether a view is scrollable),
does the accessibility job for me in all activities, and it did not
require a major program overhaul. Tested on Android 1.6 and 2.2. It is
a bit like defining the tab order when programming for Microsoft
Windows. The key thing was to discard use of dispatchKeyEvent()
altogether and "manually" do what dispatchKeyEvent() was supposed to
do in terms of moving focus to a next UI element for a generated
KeyEvent.KEYCODE_DPAD_DOWN and KeyEvent.KEYCODE_DPAD_UP.

Thanks

Understand there's logistical challenges for global distribution, but
surely it's in everyone's interest to find ways for developers around
the globe to gain access to such significant hardware updates before
high st users (well at least not months after!).
If you fancy sending a container downunder, i'm sure i'll be able to
find enough needy developers to prepay the transit.

[android-developers] Re: Fm Radio

[Bob Kerns]

Me, either. But I'll speculate as to how it works.

Phones are radios. The radio signal is processed and decoded into
audio, and fed into the audio streams. The mechanisms for this are
open source.

The FM radio signal is a radio signal that is processed and decoded
into audio. I bet it works much the same way.

So, if you're serious about figuring it out, I'd start by going and
learning how the low level phone access works (i.e. how the audio is
routed from radio to audio mixer). That part is open source.

Then I'd start reverse engineering, and find what calls the FM radio
app is making that are similar to how the phone works to set up the
audio stream for phone callls, and from there, I'd look for what's
different, that might be how it tells the radio what stream to route
to where.

I doubt there's an easier way to do it, if that's how it's set up to
work. If, on the other hand, it's just exposed as a separate device,
I'd look at what device drivers are added to the kernel, and look to
see how the FM Radio app turns it on and accesses it. (And the FM
Radio functionality does have to be specifically turned on by the app.
I'm guessing it's normally disabled due to battery consumption, but I
don't really know).

Re: [android-developers] Listview Row Animation

[Kostya Vasilyev]

There is a way to interate currently visible items in a ListView. Do that,
find the one whose data just changed, then get that item's layout, and start
your animation.

Make sure to cancel any animation in getView of your adapter, in case an
item's layout gets recycled before the animation is done playing.

Re: [android-developers] Re: Getting the already set alarm (AlarmManager)

[Kostya Vasilyev]

BTW, setting a new alarm with the same pending intent replaces any existing
alarm that used that intent.

"Same" has a well defined meaning here, look it up under PendingIntent. It
does not have to be the same Java object reference.

So if you are looking to update an existing alarm (with a new
interval,perhaps), there is already a way to do this without querying for
existing alarms.

Hi I use android.provider.Telephony.SMS_RECEIVED to listen to new SMS
message received. But what should I use to listen to MMS message
received?

Thanks

Re: [android-developers] New maps app features and mapview

They aren't?

The maps library has clearly been stagnant, with only a few changes since
1.0 (fwiw fixes for densities went in to I believe 2.2, and were back-ported
to older versions).

This is something that definitely should be improved, but I don't know a
schedule for it.  The library was originally owned and used by the maps
application, but for the application to be able to evolve as quickly as it
has (and not be tied to newer platform versions), it was changed to have its
own built-in copy of the maps library; this left ownership of the library
somewhat in limbo.

So yes we are aware of the library not getting the love it deserves, but
there is nothing concrete to report about it at this point.

Re: [android-developers] SharedPreferences not persisting

[Dianne Hackborn]

If you want to ensure the data is saved, it must be done in onPause().
 Under low memory situations, an activity can be killed before its onStop()
is called.

In my Desire phone i see both fring and Google mssagin always running
Read some about a service being "Sticky"

I read elsewhere that a service can be started with a Brodcastcmmand
http://stackoverflow.com/questions/4468006/can-i-start-a-service-without-activity-or-receiver

cant wrap my head around the code implementation here.
after reading many questions here and elsewhere about this.
I think the method is:
- an apk file which contains a Service an activity and a
BroadcastReceiver Class.
- action.BOOT_COMPLETED will start only my Service, not the Activity.
  The user can from Main Launcher start Activity for "in app settings"
and I Bind
  to Service and Unbind when done

Yea will try this tomorrow after work.

I look at your TreKing app. Im impressed nice work
That app would really been helpful this morning
when i was waiting for the buss in the snowstorm.
Can I ask how did you tap into CTA bus tracker system
GPS signal for all there Busses location?

Re: [android-developers] Re: Setting Wallpaper

Oh yeah if you want to *prevent* scrolling, you'll need to do a live

For a static bitmap image, it's pretty easy, but more than 2 lines of code.

If you have the SD card mounted on your WinXP box, that SD card is not

Re: [android-developers] SharedPreferences not persisting

[Mark Murphy]

Generally, I recommend PreferenceManager.getDefaultSharedPreferences()
to get the SharedPreferences, as that will be the one that
PreferenceActivity uses. Otherwise, your code seems fine. However,
bear in mind that onDestroy() is not guaranteed to be called, so you
may be better served writing them in onStop(), anyway.

[android-developers] SharedPreferences not persisting

[neuromit]

I've been trying to save some state variables in the SharedPrefs, this
seems to work fine when onPause, and onStop are called but not when
OnDestroy() is called. When that happens the next time my activity
loads the preference values have disappeared.

Here is the code I use to save the variables:

SharedPreferences settings = getSharedPreferences("PrivateVariables",
MODE_PRIVATE);
SharedPreferences.Editor prefEditor = settings.edit();
prefEditor.putBoolean("playingState", playingState);
prefEditor.putString("songInfo", songInfo);
prefEditor.commit();

and here is how I retrieve them:

prefs = PreferenceManager.getDefaultSharedPreferences(context);
playingState = prefs.getBoolean("playingState", true);
songInfo = prefs.getString("songInfo", " No Value ");

Is anything I'm doing obviously wrong?

[android-developers] Re: New maps app features and mapview

[JP]

Huh  interesting find, thanks!
I'm not sure in howfar Googlenav is the way to go. (I remember
com.google.googlenav from wayback in m3-rc37 and m5-rc15). There's
actually documentation around, but with the release of Android 0.9,
googlenav was booted from developers direct reach. I.e. the way I
understand, this is one of those dreaded internal libraries where
Google will give no guarantee (strike that, promise) on forward
compatibility. I guess I'll leave my fingers off of that approach,
although it's striking.

This kindof confirms how much effort has gone into the Android Maps
API. In my mind, Google should have maintained this over time and not
leave us all wet having to rely on aerobatics messing with internal
libraries. So franksmule, there's your answer, I suppose: Don't hold
your breath.

I don't think that's confusing. The last thing the user did in your app was
open the email screen - that's where they left off. So when they go back to
your app, they should pick up where they left off - on the email screen.

[android-developers] Listview Row Animation

[Petar K.]

Hello,

I have created a listview where each row contains several textviews.
In my application some of these textviews can be updated based on what
I receive from my server. I want to know how I can set an animation to
a textview in a particular row. An example could be an application
where there is a list of live games and I want to update a particular
score with an animation.I have tried to put a textview.setAnimation in
my getView of my adapter however this makes an animation on every row
of my listview when I only want it at a particular row.

Any Help would be great.

Thanks,

What are the odds that 200 devices are going to perform the same action at

I guess if you have a significantly large user base, but I'm assuming that's
not the case, or is it?

completely unacceptable?
What is so urgent about these messages that they *must* be received
instantaneously?
And regardless, there will always be some delay or lagging due to users's
network restrictions.

There's really no such thing as "keeping a connection alive". Your process
can and will be killed at some point, if not by the system then explicitly
by the user.

I would rethink what you're trying to accomplish and try to work within the

Perhaps give the user a "poll interval" or an option for manually refreshing
the data, if it makes sense for your app.

You can certainly keep your AsyncTask alive between orientation changes -
but only as long as the user keeps your app in focus as the current
Activity. Once you get put in the background you're subject to being killed.

[android-developers] start a new activity and then... come back to the old one!

[Utumno]

Hello Android gurus,

I would like to do the following:  in my app's 'Help' area, have a
button that launches the default email application and lets users drop
me an email.

That seems simple huh? Let's just create a new Activity ( code
shamelessly stolen from http://www.androidsnippets.org/snippets/29/index.html
) this way:

final Intent emailIntent = new
Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("plain/text");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]
{"t...@email.com"});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
"Subject");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Text");
context.startActivity(Intent.createChooser(emailIntent, "Send
mail..."));

now, that *almost* works. Almost, because there are two problems with
it:

1) when user exits the mail application ( either by actually sending
the email or simply by pressing the 'BACK' button ) then he gets
kicked out of my app entirely ( back to the main screen, while it
should go back to my app! )

2) when having the email application on top, user presses the 'HOME'
button, the Android correctly comes back to the main screen. However,
when I now re-launch my app, user lands in the mail application again,
which is confusing. I would like him to get back to my app's main
activity.

Adding the following line

emailIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);

does not help.

Or, design layouts that adapt well to different screen sizes, and

If you are looking to install the application, there are no other

definition of "loading an application", please explain further what

An SMS "inbox" is not part of the operating system, but rather is part
of each and every SMS client. You are welcome to contact the authors
of SMS clients and ask them how to do it with their product. The
Messenger application that is part of the Android open source project
does not have a documented and supported API for this.

You can "copy the DB and store it as some example on the web suggest".
Store it as an asset or raw resource and copy it to the filesystem on
first run.

[android-developers] Re: App disappeared from Market Home

[Chister Nordvik]

Be careful updating now, I just tried and the following happened:
- The app disappears
- The category changes to games (if you forget that the console
changes the category to games when you edit...)
- Next time you edit it (by tweaking the URL) you get screenshots and
icons from the first time you published it. I got 1 year old icons.

So I decided that this is not the weekend to update any apps. I know
that Google are updating the market but I really can't understand why
they cannot just make the console unavailable instead of developers
experiencing buggy behavior like this.

[android-developers] Bitmap.createBitmap vs. Decodestream alpha performance

[olivier]

Hi,

I'm loading transparent PNGs into bitmaps using two different methods.
The first being BitmapFactory.decodeStream() of a resource stream. The
second being Bitmap.createBitmap(), populated by a Bitmap.setPixels()
call.

When drawn on a canvas, the bitmaps loaded by decodeStream() perform
significantly better. At first I thought the difference might be due
to using a createBitmap() overload that returns a mutable bitmap, but
changing it to return an immutable bitmap did not cover the difference
in performance.
Calling getConfig() on the bitmaps returned by decodeStream() returns
null, could the bitmap have been converted to an ARGB1555 or similar
format internally? Is it possible to get the same configuration using
createBitmap() with setPixels()?


// Method A ~55FPS
BitmapFactory.Options sBitmapOptions
= new BitmapFactory.Options();
sBitmapOptions.inPreferredConfig = Bitmap.Config.RGB_565;
InputStream is = context.getResources().openRawResource(resource_id);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, sBitmapOptions);

// Method B ~45FPS
Bitmap bitmap = Bitmap.createBitmap(width, height,
Bitmap.Config.ARGB_);
int length = (width*height);
int[] arrColor = new int[length];
// fill arrColor
bitmap.setPixels(arrColor, 0, width, 0, 0, width, height);

Thanks

Subject: [android-developers] Re: Determining in advance how much text will fit 
into a given TextView?

Yes, but I can only apply this math if I know how the text will be
word-wrapped. This means that I have to word-wrap it myself and then
do the calculations.

The problem with this is that I may not wrap the text the same way
that the TextView (or other subsidiary object) wraps it.

I'm sure I can dig through the source code to find the algorithm that
the appropriate Android object uses to perform the word wrapping.
However, there is no guarantee that this is the same algorithm that
will be used in other Android versions. Therefore, my code might break
when run in the future.

For that matter, future versions of Android might also manage spacing
and fonts differently than today's version.

This is why I was hoping for a way to query Android objects,
themselves, to find out exactly how much text will fit into the
visible area of the View. If this info were returned via method calls,
it would be a lot less likely that future versions of these methods
would fail to provide the correct data for the given Android version.

But I guess I'm just SOL about this. It's too bad that Google didn't
see fit to encapsulate the functionality that I'm looking for. I
couldn't possibly be the only person who would need it.

[android-developers] EditText inside ListView

[Andy Savage]

I've found a plethora of older unanswered questions about this, so I'm
adding one more in the hope that someone has now found a solution.

I have an EditText inside a ListView (Specifically its in a custom
Preference inside a PreferenceScreen, but a simple ListView is enough
to replicate it). When the EditText is touched, the software keyboard
is popped up and the EditText "loses focus". You can retouch the
EditText and try to type, but when the predictive text suggests a word
it again "loses focus" and empties itself.

Upon inspection the EditText's parent view is being recreated, which
explains the losing focus and content. Digging a little deeper
Preference's getView(View convertView, ViewGroup parent) is being
called with a blank convertView, rebuilding the entire view rather
than reusing the existing one. I don't know if that's the right place
to be looking, or if that is normal for a ListView child. The view is
also recreated as the user scrolls (which makes scrolling somewhat
slower, but that's another issue).

I don't really know where to go from here. A PreferenceScreen expects
a ListView so I can't just change the view to LinearLayout or
something. I also don't really want to give up the custom EditText
preferences as they fit very well in the context they are being used.

Any ideas on how to stop this issue would be great.

Subject: [android-developers] Re: How to simulate a (missing) DPAD

Thanks Mark. I can easily detect touch events by their coordinates,
but not so easily identify what UI elements lie underneath - unless I
define and layout each of these UI elements graphically myself in
terms of screen coordinates. I think your proposed TalkBackOverlayView
would require that too, if I understand you correctly. My main screen
already uses different touch screen events for gross positions like
center, top middle, left middle, bottom left and bottom right, and
speaks the relevant user actions. Here I did without an exploration
mode, although that should have been easily possible through handling
ACTION_DOWN and ACTION_UP events separately in dispatchTouchEvent().
This very basic level of touch screen use is indeed accessible for
blind persons, as are the keyboard shortcuts that I have defined for
phones with a physical keyboard.

However, at some point one would want to make good use of standard UI
elements (listviews, buttons, radio buttons, checkboxes etc) for which
Android determines the concrete layout instance, and render these
standard elements accessible rather than having to define a range of
dedicated touch views corresponding to each and every activity view
that sighted users would use. I have no ambition to reinvent the
Android layout framework. The iPhone, through VoiceOver, offers a
generic touch screen solution for this as part of the OS. I feel that
any accessibility "hook" for standard UI elements that I add at
application level to my specific Android app should be only an interim
solution and a stop gap until Android catches up and offers a
similarly general accessibility solution as part of the OS. Otherwise,
blind users will in the future at best have a few accessible point
solutions, but no general accessibility with phones that lack a
physical keyboard and/or d-pad.

Now while trying to bridge the current accessibility limitations for d-
pad-less Android phones, apparently even a simple key remapping is not
that, erm... simple, with the current set of event Listeners and
onWhatevers(). :-(

[android-developers] Re: New maps app features and mapview

[Igor Korobka]

I've solved the issue with small labels on the google maps on hdpi screens.

You need a bit of reflection (see the snippet of smali code below): 

class com.google.googlenav.map.MapTile {

.field public static final TEXT_SIZE_DESKTOP:B = 0x0t
.field public static final TEXT_SIZE_LARGE:B = 0x3t
.field public static final TEXT_SIZE_MEDIUM:B = 0x2t
.field public static final TEXT_SIZE_SMALL:B = 0x1t

.field static textSize:I
}

Setting static field textSize to constant value  TEXT_SIZE_LARGE at the end 
of onCreate method makes a miracle - labels on the maps become large enough 
to read easily.
Note: you need to clean application cache to kill old map tiles.

[android-developers] Problem adding sensor library for new device

[db]

Hi folks,

I have written a sensor library to support a new device I am working on. I 
have written a very simple application to get a reference to the 
SensorManager, register a listener, and get updates on changes. However my 
app never gets any updates, and upon debugging I found that the 
SensorManager thread was never getting started. It turns out that this is 
because SensorManager.SensorThread,startLocked() fails to get a data channel 
to the SensorService (service,getDataChannel()) throws a read exception.

So my question is: does anyone who is familiar with the internals of android 
know why this might be happening? Is there something that I might need to 
configured in android for my target device so that RPC works correctly? Any 
suggestions about what else to look for to get clues about what may be 
happening?

Thanks!

OK, that explains it. I think what's happening is each entry in your list is
being created using the table layout you defined. So basically you have a
list of tables, not a single table with rows, and they're all independent
and won't line up.

Honestly not sure if this would work with an adapter as you have it.

An alternative would be to just create a TableLayout and add each row into
it dynamically from the data in your cursor.

Or wait for someone who knows more about CursorAdapters and Tables to help
you out :-)

[android-developers] Standalone product using Android

[A K S]

Friends,

I wanted to develop a product which will run only my application. The
product will not be kind of mobile. That will help certain group of
people to use. The product will have nothing to connect to emails,
chat or other mobile features.

So can I do that with use of Android? If so, what should be the
requirements for the product hardware?

Or does this Android comes only for mobile & Pads?

Help me pls.

AKS

[android-developers] google analytics jar and notifying my app users

[David Liebman]

Hi,

I have a game app that I'm working on. I've already published a
version on Android Market. I've heard about the google analytics jar
from the following sites.

http://android-developers.blogspot.com/2010/12/analytics-for-android-apps.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+blogspot%2FhsDu+%28Android+Developers+Blog%29

http://code.google.com/mobile/analytics/docs/android/

I have installed the jar as a library in my app on eclipse, and now I
need some advice before I put another version of the app on the
android market. On the google code site it's stated that:

"You must indicate to your users, either in the application itself or
in your terms of service, that you reserve the right to anonymously
track and report a user's activity inside of your app. Your use of the
Google Analytics SDK is additionally governed by the Google Analytics
Terms of Service, which you must agree to when signing up for an
account."

How should I go about notifying my users that I'm making a change to
the app that involves tracking usage with Google Analytics? I already
have a Google Analytics account, and so I believe I have already
agreed to the 'Terms of Service".

So the question is, how do I notify my users that I'm using Google
Analytics?

Thanks
