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

[gjs]

Hi,

I think you could still extrapolate (average) speed for some trip with
intermittent GPS signals.

If you get a GPS fix at the start of the journey and then at the end
you can calculate an average speed based on the time duration and
straight line distance between these points, any additional points
(GPS or course grained towers/wifi/skyhook) during the journey would
be a bonus to increase the accuracy of the speed and distance calcs.

This depends on whether you actually require real time speed ?

Regards

[android-developers] Re: I ask for power off but get reboot instead sometimes

[Zsolt Vasvari]

Yes, I have the exact same problem.  Once in a while it will reboot if
I select the Power Off option.  But the touch screen is very flaky.  A
lot of times when I have it connected in debug mode, it loses
calibration and I have to put it to sleep and back on to get it
fixed.  So it could be just the screen calibration is getting out of
whack and it thinks it's hitting a different button.

As far as the HW problem, I also had to have my N1 replaced once due
to a faulty power switch.

Of course. I just meant in this case the public and private classes do
share the problems.
If one day you'll replace NumberPicker, wouldn't that also cause
troubles to keep Date- and TimePicker compatible?

Sure. If the "old crap" is only in apps which cloned it, you can
savely remove it from the system core. I wouldn't like to drag along
two similar, incompatible variants of widgets for the same purpose as
well.
Maybe I just underestimated the possible compatibility issues. My
thoughts were along the lines "Range in, number out - there's no
complicated interface. And a wheel like the one posted above could
easily fit the current widget size." But I don't know what you've got
in mind for future implementations...
Anyway. You've done so many good extensions in the past, I'm positive
you'll find a good solution with an upcoming update.

[android-developers] Listening to HFP events

[qwesthead]

We've a bluetooth application which uses SPP protocol. For better

related events like Bluetooth connected/disconnected. Is that
possible? Is there a list of Bluetooth events that we can listen to?

[android-developers] what is HIPRI connection

[Zhihong GUO]

Hi all,

There is a kind of connection called HIPRI, which is categoried by Android
as a connection like MMS, or SUPL, DUN or Mobile. It is said by the SDK web
page that it is :

A High Priority Mobile data connection. This connection is typically the
same as 
TYPE_MOBILE
but
the routing setup is different. Only requesting processes will have access
to the Mobile DNS servers and only IP's explicitly requested via
requestRouteToHost(int,
int) will route over this interface if a default route exists.

I am not very clear about the description. If we start connection on HIPRI,
will the connection be teared down when Wi-Fi connection established?

If we use the connection after there is Wi-Fi connection, that means, we
want to make dual connection on Wi-Fi and HIPRI, do we have to use the IP
explicitly request instead of the string like http://www.google.com?

Thanks

[android-developers] Performance issue with mapview when using large number of items

[Stephan Wiesner]

Hi,
my app is supposed to display about 7000 items on a mapview (distributed
over a whole country), but I have serious performance issues with this.
Currently I only display the items that are in an 15km radius of the center
of the map (user has to press a button for this) and everything works fine.
I would prefer to show all items at start, though. That is possible, but
moving the map around becomes very slow (guess I need that new LG phone
after all :-).

I extend ItemizedOverlay and the problem seems to be in


public void draw(Canvas canvas, MapView mapView, boolean shadow) {
if (canvas != null && mapView != null) {
super.draw(canvas, mapView, false);
}
}

if I comment out the call to super, the moving of the map is smooth (but of
course nothing is displayed).


Any hints?
Thanks,
Stephan

[android-developers] Re: HttpURLConnection gives UnknownHostException

[Bob Kerns]

UnknownHostException means your device was unable to get a positive
response to the DNS query trying to look up the hostname.

It doesn't distinguish between "We couldn't talk to the DNS server",
"we have no network connection right now", "we have never even HEARD
of net work, what's that?", or "we carefully and thoroughly discussed
it with the DNS server, which in turn discussed it with the relevant
authoritative DNS servers, and can conclusively state, that the host
named does not exist at this time".

What you CAN say, is it never got to the point of actually trying to
talk to that host, because it didn't get enough information to do so.
That is, it is not saying "we've heard of that host, but it doesn't
seem to be there".

The most likely cause is a temporary failure in your wifi connection,
just as it was trying the DNS lookup. But the DNS server itself could
be to blame, or if it's a DNS server on your site, the connection
upstream, or an upstream DNS server could be to blame.

I use my local wifi server as a DNS server. It's been giving me
problems like this lately, even on wired connections. Plus, it is not
compatible with IPv6, so I'm going to need to upgrade it soon. I could
configure it to advertise OpenDNS servers instead (which is what it
itself is using), but have slightly longer lookups and no cached data
if the cable connection hiccups. If it's the cable connection that's
at fault, then I'll have these problems anyway. It won't be easy to
track down.

Re: [android-developers] Gingerbread BroadcastReceiver Issue

[Dianne Hackborn]

Services will be occasionally killed in the background if they aren't set to
be foreground.  This is all normal behavior.  You control what happens when
they restart (if they restart at all) through what you return from
onStartCommand().  It looks like you are not explicitly returning anything,
and haven't set your target SDK version to be >= the 2.0 level, so you are
getting the old behavior.

pressure is very different than 10 bytes describing the high score to
ultimately post on a web site somewhere when it gets around to
updating. It makes a real difference how quickly and reliably the data
is delivered.

10 bytes of data when it is describing a selected record in a large
database is very different from 10 bytes of data which describe
geographic coordinates on the earth's surface. In the latter case,
there's a frame of reference that even a space alien can understand
without a device. In the former, you need not only the database, but
the particular process of selection, which may in turn involve
information known only within the same process.  Those 10 bytes may be
meaningless by themselves, taken out of the context in which they have
meaning.

10 bytes is 10 bytes -- so long as you don't care about what those
bytes mean or why they exist. That is, if they're worthless. If
they're valuable, on the other hand, it's a whole other story.

[android-developers] How to get raw data from audio decoded buffer

[npak243]

Hi everyone,

Does anyone know how to decode an audio file (i.e *.mp3) to raw data
by using a certain class on Android? Because I want to use the decoded
data rather than using MediaPlayer to play audio file directly.

Thanks,
NPAK

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

[Bob Kerns]

I've never gotten around to experimenting to see just how good you CAN
get -- but there are some reference points that should help
considerably.

* Gravity
* The magnetic field
* Any period of low acceleration noise in the vicinity of about 1 g
total acceleration probably indicates it has been set down on a
surface (or in the original scenario -- the car has come to a stop).

There other possibilities in other situations:
* Camera data can indicate relative motion
* Acoustical echoic signature and ambient sounds
* Wifi transmitter signal strengths
* 3G signal strengths. (Hey, I'm outdoors, maybe try GPS again!)
* Sonar!

A typical android device has more senses than humans. We synthesize an
understanding of our location and environment via a process of sensor
fusion. There's more opportunity for this sort of thing on Android
than Nintendo, as there's more processing power available and more
sensors to gather information -- especially when connected to a power
source or otherwise on a larger power budget than a cell phone. Look
at Dempster-Shafer Theory and Kahlman filters for techniques to handle
this sort of process.

[android-developers] Minor ListView UI Issue

[Paul]

Hi all.  I have an app based on Notepad example app, and one thing
that 'bugs' me is that on insertion of a new note, the user can see
the new  item at the top of the ListView for a split second
before being taken to the EditText-based activity; I'd love for the
item to not be shown at all before the UI changes to the EditText
screen.

Looking at the EditText onCreate, I am calling setContentView() before
the note is inserted by the getContentResolver(), so trying to figure
out why the user can see the insert action of an Activity that is
called AFTER the view is set in onCreate of the activity... is this
due to simple lag between the time the setContentView() call happens
and the time the view can be expanded from XML?  Are views only
expanded at the end of onCreate, and thus this is happening after the
insert action by design?

Any information appreciated!

Paul

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

[ip332]

You can get location from NETWORK_PROVIDER which can be calculated
from cell towers or WiFi AP.
The first one works almost always but the accuracy is not good
therefore you may get the same location for quite a long time.
All you need to do is to replace GPS_PROVIDER with NETWORK_PROVIDER.

Re: [android-developers] Gingerbread BroadcastReceiver Issue

I did some log searching, and found that this happens before the service 
stops working:
01-12 23:26:14.268: INFO/ActivityManager(109): No longer want 
com.jakebasile.android.hearingsaver (pid 31188): hidden #16

But afterwards, the service no longer works correctly. My onStartCommand 
isn't called, so the receiver doesn't get re-registered.

I don't understand why it would be a "crashed service". There is no error 
info being printed, and my code doesn't really *do* anything to cause a 
crash. Any ideas?

[android-developers] Cursor Position in EditText

[Paul]

Maybe more of an FYI than a question, but in playing around with
setSelection() with an EditText, it appears that:

- setting the position to anything above 0 works as expected, i.e.
mText.setSelection(3) puts the cursor at position three, but;
- setting the position to 0, i.e. the top-left position of the text,
fails, instead placing the cursor at the end of the first line of
text.

.setSelection(3):
Lorum ipsum...
^

.setSelection(0):
Lorum ipsum...
  ^

Anyone know of a way to have the cursor at position 0 when there is
existing text in the EditText, and maybe more importantly, any best
practices as to what a user would expect?  I have a large multi-line
EditText on a tablet, do I emulate Word and have the cursor at
position 0, or have the cursor at the end of line 1 as Android seems
to insist (which makes sense for a single-line EditText), or maybe at
the very end of the text, which could be way down on line n?  Having
the cursor at the end of line one of a multi-line entry seems to not
really help anyone.

Thanks for any thoughts,

Paul

Play a tone and record it at the same time.  The doppler shift should

Re: [android-developers] SQLite database is puffed every time I run my app.

[Kumar Bibek]

You should change your Version of database to let it call the onUpgrade
method. Really, it should. And, the onCreate should not be called everytime.

It seems that your onUpgrade method is being called, and everytime you run
the app, it deletes all the tables and recreates them. That should explain
why your tables are empty. Check the logcat for more info. It should be
there.

[android-developers] strong BlurMaskFilter

[Rob Truxler]

Hi everyone.  I'm doing some custom rendering on a Canvas object, and want
to achieve a visible white glow behind some text. I'm using a Paint object
with a BlurMaskFilter:

Paint p = new Paint();
p.setColor(0x);
p.setMaskFilter(new BlurMaskFilter(4f,BlurMaskFilter.Blur.OUTER));

I can see the blur, but it is very very faint. Is there any way to beef up
the alpha values? I tried rendering with this paint object multiple times
and this does make the glow easier to see, but it makes for inefficient
rendering.

Thanks, Rob

Re: [android-developers] Sharing data between apps

[Dianne Hackborn]

Your apps are in two different sandboxes.  They are protected from
themselves, just like they are protected from other apps.  That's the way it
is.

SharedPreferences doesn't mean a big data pool that all of the applications
installed on the device share.  It is just shared amongst the components of
an app.

You've been given the 4 main components used for interaction between two
apps.  10 bytes is pretty small, so any of those will be totally sufficient
to get 10 bytes from here to there.  Just use one of them.  A broadcast
receiver is probably the easiest.

[android-developers] Re: Comparing values afterTextChanged

[Bob Kerns]

Um, no -- you're trying to make a good point, but it ends up being bad
advice, because you hit it with too big a hammer... I'm glad you
tried, though.

You really MUST use == when == is the right thing -- and must not use
it otherwise. Primitives are just one case. It's important to
understand what == does, and what .equals() does.

As you note, comparing two strings, say, with == simply compares that
they're physically the same object. This isn't very likely to be
useful for strings. Since they're immutable, one string is generally
as good as another, so long as they contain the right characters.

However -- if your question is "if I modify this object reference,
will that affect that object reference?", then equals() is the WRONG
question to ask.

One way to look at it is .equals() asks about equivalence, while ==,
when applied to an object (rather than a primitive) asks about
identity.

Now, it's reasonable to ask whether you should ever have equals()
return true and == return false in any case when identity might
matter.  In general, I would suggest avoiding that, just on the
grounds of potential confusion. equals() implies a type of
equivalence, while if the identity matters (say, because of instance
state not compared in the equals() method, that says they're not fully
equivalent.

But there often is more than one notion of equivalence at work in a
system. For example, equals() may be defined for supporting use as a
key in a hash table, and thus must consider only immutable fields.

And even if they would both return the same answer, it is better to
use == when that is, in fact, what you are asking. Using equal() on a
mutable instance when you care about identity is itself misleading and
confusing.

If you want to capture this in a short phrase, I'd suggest "same
object (==) vs same content (equals())". Where "same content" means
whatever equals() defines it to mean.

[android-developers] Re: I ask for power off but get reboot instead sometimes

[metal mikey]

@TreKing: I feel your paaain! As an early adopter/enthusiat residing
in Australia, I get the added pain of having had my NexusOne
personalised (so a replacement is not an option), HTC support based in
USA, taking calls only around USA business hours, and issuing FedEx
mailing instructions that are only valid for 7 days (hence I saw fit
to not even try to send it over before Christmas). Fun times :/

As for turning it on, there is the trick you can employ whereby you
hook USB power to your NexusOne and then "trash" the battery in and
out until the phone gets duped into powering on. Make sure to quickly
change your settings so the display doesn't sleep, because that power
button is also the only way to wake it up.

Given that the power button is a major failing point of the NexusOne,
I think it would be very, very nice of Google to provide an official
update for the NexusOne that allows an alternate means of waking the
phone up (i.e. via the trackball button), as then my phone could be
safely taken off "life support" (i.e. the usb power connection).

You can use path separators in Android. You just cannot use path
separators in openFileOutput(). That's one reason why I don't use
openFileOutput(). Just use standard Java I/O.

Use a broadcast Intent and a BroadcastReceiver. Or any of the

They are shared among components in an app. They are not shared
between applications, between devices, between neighboring countries,
or between consenting adults.

You can't specify a path in the call to openFileOutput().  (Fails if there
are any path separators)
Hard to specify another apps directory if you can't use path separators.

10 bytes of data is 10 bytes of data.  10 binary bytes.  Not text.
Only needs to be transferred occasionally, but does need to be transferred.

So, what you are saying is there is NO easy way to transfer a tiny bit of
data.
App X just needs to send it to App Y when the user does certain actions.
sigh.
(In this case there are 2 apps, either of which can be used independently,
but if both are on the phone, they can work together.)

A SharedPreference would have been perfect - but the "Shared" prefix seems
to have a different meaning than what you would think.

That is not the proper use of an Activity.

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

[keyboardr]

I know Nintendo originally tried to use accelerometers to figure out
where it was pointing, and while that's theoretically possible, in
practice the accuracy just isn't good enough.  The acceleration most
of the time is small enough that even the slightest error will throw
the whole calculation way off, and since you're relying on all of your
previous results, errors get compounded over time.  That's why
Nintendo switched to an IR camera setup.

Re: [android-developers] sqllite

[Hendrik Greving]

KEY_STRING is the text column name

When putting in KEY_STRING + " like " + mystring => I am getting a syntax 
exception
KEY_STRING + " like \"" + mystring + "\"" => it seems to incorrectly always 
find something

Actually, I want only exact matches, no substrings anyways

[android-developers] Sharing data between apps

[John Lussmyer]

I've been looking to see if there is a relatively simple way for 2 apps to
share a tiny bit of data.
So far, I haven't found any.

1) SharedPreferences - aren't shared.
2) MemoryFile in Shared Memory - there appears to be no way to share these
between apps.
3) Internal Storage - separate apps can't write to each others area, even if
they have the same userid.
4) External storage - may not exist.

So, in order to send 10 bytes of data to another app, it seems that I'll
have to create a new Activity and have it respond to an Intent().
Is that really the only way to do this?

[android-developers] Re: clicking a link on a website launches my application...

[sdphil]

that sample was great except that it doesn't show what the link the
web site looks like.  I assume it looks like what I have.  The problem
is that the browser is trying to redirect when I click on it instead
of giving the intent to my app.

Yep, NexusOne is great an all but sucks on a few levels...you're lucky
you can even use your power button! (I can't, it failed on the day I

[android-developers] Re: HttpURLConnection gives UnknownHostException

[Dan]

Hello All,

I have had this error both on emulator and a Motorola Droid while
using a WIFI connection.  I have surrounded the http request with WIFI
state checks and before and after WIFI is reported state 3
(WIFI_STATE_ENABLED) and a connection speed of 54 . I have also
confirmed, using an adb shell with the emulator, that the emulator
cannot ping the website in question giving a domain resolution error.
To compare notes with Ankur, is the server on your LAN and the IP used
internal? mine is.

I have also tried AndroidHttpClient which does work on the same url.

[android-developers] Re: HttpURLConnection gives UnknownHostException

[Dan]

Hello All,

I have had this error both on emulator and a Motorola Droid while
using a WIFI connection.  I have surrounded the http request with WIFI
state checks and before and after WIFI is reported state 3
(WIFI_STATE_ENABLED) and I also . I have also confirmed, using an adb
shell with the emulator, that the emulator cannot ping the website in
question giving a domain resolution error. To compare notes with
Ankur, is the server on your LAN and the IP used internal? mine is.

I have also tried AndroidHttpClient which does work on the same url.

[android-developers] SQLite database is puffed every time I run my app.

[Tobiah]

I took my code from the NotePad tutorial:

private static class DatabaseHelper extends SQLiteOpenHelper {

DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {

Log.e(TAG, "CREATING DAG");
createDB(db);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int 
newVersion) {
Log.e(TAG, "Upgrading database from version " + oldVersion + 
" to "
+ newVersion + ", which will destroy all old 
data");

db.execSQL("DROP TABLE IF EXISTS scan");
db.execSQL("DROP TABLE IF EXISTS notes");
db.execSQL("DROP TABLE IF EXISTS attendee");
db.execSQL("DROP TABLE IF EXISTS attendeeqanswerlink");
db.execSQL("DROP TABLE IF EXISTS lead");
db.execSQL("DROP TABLE IF EXISTS leadnotes");
db.execSQL("DROP TABLE IF EXISTS qanswer");
db.execSQL("DROP TABLE IF EXISTS qquestion");
db.execSQL("DROP TABLE IF EXISTS rolodex");
db.execSQL("DROP TABLE IF EXISTS showinfo");

onCreate(db);
}
}

I can tell from the log that onCreate() is being called every time I start up 
my app.  onUpgrade() is not
being called.  I can add data to the database using rawQuery().  While the app 
is running I can pull
the database file to my dev box and select records from the copy.  If I restart 
the app, then pull
the database, it's empty.

What could be wrong?

Thanks!

Tobiah

[android-developers] C++ exception support confusion

[Allen Curtis]

Hello,

I am in the process of porting C++ libraries to Android that use libsigc++. 
However I am confused about the support provided in the NDK.

The Stable APIs document states the following:
C++ Library:

...
They may not contain all definitions required by the standard. Notably,
support for C++ exceptions and RTTI is not available with Android 1.5 system
images.


The Standalone Toolchain document states this:
5.3 Exceptions, RTTI and STL:
- - - - - - - - - - - - - - -
The toolchain binaries *do* support C++ exceptions and RTTI by default.


Can someone clarify?

TIA

[android-developers] Can't find Activity error

[John Lussmyer]

I'm trying to use an Intent() to send a little data to another app.
So far, I've been unable to get the startActivity() to succeed.  It always
fails with a ActivityNotFound exception.
I just haven't been able to figure out WHY my activity isn't being found.

invoking code is:

Intent intent = new
Intent("com.casadelgato.lifewallpaper.UPDATEPREFS");
intent.setPackage("com.casadelgato.lifewallpaper");
intent.putExtra("PrefUpdate", true);
startActivity(intent);


Manifest of target app is:


http://schemas.android.com/apk/res/android";
package="com.casadelgato.lifewallpaper"
android:versionName="1.0.3"
android:versionCode="4"
android:sharedUserId="@string/SharedUserID">

No it doesn't. Like what "ask for power off" means.


Press and hold power button, then press "Power off" in menu selection of

[android-developers] AccountManager undocumented exception returns "unknown authTokenType"

[H]

Hi,

I'm calling the AccountManager like this:

accountManagerFutureOld = mAccountManager.getAuthToken(mAccount, "cl", 
false, null, null);

The Account being passed in is a Google account (type="com.google").

This works perfectly well for thousands of users of my app. But a handful of 
times each day, some users are getting this error

java.lang.IllegalArgumentException: unknown authTokenType
at 
android.accounts.AccountManager.convertErrorToException(AccountManager.java:1093)
at android.accounts.AccountManager.access$500(AccountManager.java:74)
at 
android.accounts.AccountManager$AmsTask$Response.onError(AccountManager.java:944)
at 
android.accounts.IAccountManagerResponse$Stub.onTransact(IAccountManagerResponse.java:69)
at android.os.Binder.execTransact(Binder.java:287)
at dalvik.system.NativeStart.run(Native Method)

This isn't an exception that the javadoc says comes from this method!

I think this is coming from the 
AbstractAccountAuthenticator.getAuthTokenLabel(IAccountAuthenticatorResponse, 
String) who in turn catches this exception from the concrete 
authenticator's getAuthTokenLabel(String) method. I've decompiled the gsf 
and looked in this method, but can't see any throw of 
an IllegalArgumentException in there. All it really does is call the 
PackageManager.getPermissionInfo() and retrieve attributes of the 
PermissionInfo returned.

Looking at the details for the reports, I *think* these reports are only 
coming from non google devices - for example the reported models include 
MID-7AS, XT800, EFREN II, etc. I don't see any mentions of nice devices like 
Desire or Nexus, etc.

At first I thought this was just people forcing my app onto a non gapps 
device, but the fact that they have a Google account on the device which can 
be happily enumerated and retrieved using the standard api (i.e. 
type-com.google) makes me think they at least have the full google services 
framework otherwise they wouldn't have the GoogleLoginService.

So does anyone know exactly what this error thinks is missing..? Is there 
any way to spot this before trying the call?

Well, you're setting up a layout programmatically, for starters.

If you insist on doing it this way, make sure you also explicitly set
LayoutParams where appropriate. Maybe also set layout weight on the
ListView.

Re: [android-developers] Re: Particularity running modified standard app

[Kostya Vasilyev]

Check the manifest for your custom version, to see if there is an activity
with an intent filter that is launched by a specific action name (as opposed
by class). I'd think there might be. If so, change the action string to be
different from the standard application in the manifest and in your code.
Check broadcast receivers as well.

Oh, and there is no such thing as "clone of another application" to Android.
If you use the same action strings, or package names as another app, you're
asking for trouble.

Re: [android-developers] Sharing preferences between apps?

[Dianne Hackborn]

Each app is in its own sandbox.  You should use one of the standard
components for interacting between them -- activity, service, receiver,
provider.

[android-developers] Re: Confusing IllegalArgumentException from openFileOutput

[John Lussmyer]

Figured it out.
Apparently, even though you are allowed to getFilesDir(), you aren't allowed
to actually specify that directory in a path.
The file name you pass to openFileOutput() must be a relative path to that
directory, and may not specify that directory.
Intuitively obvious that isn't.

[android-developers] Re: Comparing values afterTextChanged

[H]

No worries.

I should probably clarify a bit by saying that you should only really use 
the "==" when comparing primitives. For non primitives (e.g. any Object 
class - basically anything that starts with a capital letter), most of the 
time, you are probably wanting to use .equals.

Remember that the .equals class can be overriden on any class so some 
classes can customise and choose exactly how to test for equality. If you 
use the "==" then you have no choice in how that test is run other than the 
default way which compares the memory references.

[android-developers] Re: SensorManager failing to start listener thread

Hi,

I found the problem: there was an error in my sensor library that caused an 
invalid file descriptor to be returned from control__open_data_source().

So if anyone else runs into a problem like this, definitely check that your 
sensor library is returning a valid file descriptor. :)

[android-developers] (Unknown) contact showing up after a modify

[Simon MacDonald]

Hi all,

I have a weird issue on an Android 2.2 device.  I have an existing
contact and I do a modify operation on it via:

ContentProviderOperation.Builder builder =
ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
.withSelection(ContactsContract.Data.CONTACT_ID + "=? AND " +
ContactsContract.Data.MIMETYPE + "=?",
new String[]{id,
ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE})
.withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME,
displayName)
.withValue(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME,
familyName)
.withValue(ContactsContract.CommonDataKinds.StructuredName.MIDDLE_NAME,
middleName)
.withValue(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME,
givenName)
.withValue(ContactsContract.CommonDataKinds.StructuredName.PREFIX,
honorificPrefix)
.withValue(ContactsContract.CommonDataKinds.StructuredName.SUFFIX,
honorificSuffix);

mApp.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

The contact gets modified correctly.  All of the new values show up
for the Contacts name.

However, if I look in my Contacts app there is a new contact called
"(Unknown)" that shows up after I do a modify.  I can insert as many
contacts as I want but every modify creates a new "(Unknown)" contact.

Anyone have any ideas?

[android-developers] WebView pauseTimers()

[Dan]

Hello All,

I am working on a an application that it trying to use the
WebView.pauseTimers() API. I am still getting console messages from my
JavaScript setInterval method after calling pauseTimers(). I was
wondering if this is a known problem, could I be missing a step, or an
alternative API that will suspend the setInterval timer.

Thank you,
-Dan

[android-developers] Google Voice SMS "sms_body" not working

[Jas]

I use the following code to start the SMS application:

Intent smsIntent=new Intent(Intent.ACTION_SENDTO,
Uri.parse("smsto:"));
smsIntent.putExtra("sms_body", "Message Body");
startActivity(smsIntent);

 It works fine if user selects default "Messaging" application. But if
user selects GV the message body text is not populated.

I have searched all the forums I know off and tried lot of things.
Nothing worked for me. I don't have any filters or permission in
Manifest file specific for SMS.  Am I missing something here? Does GV
need a special handing that it can’t be treated as same as default
“Messaging” app?

If I can't fix it, I would prefer to remove the GV from choices
offered to users. How can I start the default messaging app with body
text filled in, without offering any choices to user?

Please help or provider any direction for debug.

Do that then.


Well, it gets curioser and curioser.

Please fasten seatbelts for what follows.

Before describing what happened when I did change the package name, I 
have to say that without knowledge of how Android keeps different 
applications/tasks apart to protect the operating system and other 
tasks, I think the present scheme defective.


It seems to me that the standard expected behavior is that two distinct 
applications, even if one is a clone of the other, should operate 
completely independently (unless of course they are sharing peripheral 
hardware), and no matter what one does in one application (no matter how 
stupid) should cause anything to happen in the other. Just for the 
record, in all that follows, at no time are the two camera applications 
(factory and mine) running at the same time.


So. I uninstall the previous version of my app. I change all the 
"com.android.camera" to "x.y.z" everywhere with refactor and global 
search/replace. Eclipse is happy, says there are 14 warnings, which is 
what I got with the original camera app.


I now run my app from Eclipse and result is the same! (to recap: running 
from Eclipse I see my mods; running from my mods installed on phone by 
Eclipse I get standard camera app.).


So at this point, I impishly wonder what will happen if I power off (I 
get a reboot instead, but why argue...?)? I run my mods from app 
launcher. Hooray! I get my mods. I kill my mods with Taskiller. I now 
run standard camera app. I get my mods instead!!!


I am in a bit of a bad mood now, and ask what I have wondered silently 
for months just using the phone as a user, viz. is this thing ready for 
prime time?

Re: [android-developers] Re: Soft keyboard alters layout

[Kostya Vasilyev]

Neil,

The link provided by TreKing says that:

With the standard IMEs, you will only encounter this situation when 
the screen is in a landscape orientation, although other IMEs are free 
to use it whenever they desire. In this case the application window is 
left as-is, and the IME simply displays fullscreen on top of it.


So looks like there is no universal way to get this mode.

You could try setting this on your activity in the manifest:

android:windowSoftInputMode="stateVisible|adjustPan"

This will move the entire layout of your activity up if needed, but only 
as far as necessary to show the control being edited.


Your edit control should be above the navigation bar, so the bar is 
covered by the keyboard itself.

[android-developers] I ask for power off but get reboot instead sometimes

[higonnet]

Subject line basically says it all.

As a completely wild guess, I'd say this happens 10% to 15% of the
time, on my unrooted, normal Nexus One.

I find this disconcerting at best, since the reason I'm powering the
thing off is that it isn't behaving the way it usually
does...

Not at all sure of following, but seems to happen more with 2.2 than
before?

You can't test for equality on a String using "==" as that will just check

Do that then.

You can't publish applications that use "com.android.*" or "android.*" 
for package name anyway.

[android-developers] ListView seems to consume screen from its location downward.

[Tobiah]

I'm making my screen up programmatically:

LinearLayout l = new LinearLayout(this);
l.setOrientation(LinearLayout.VERTICAL);

l.addView(getBarcodeButton());

result = new TextView(this);
result.setText(borg.phone_number);
l.addView(result);

ListView lv = new ListView(this);
String[] a = {"cat", "dog", "foo", "bar", "cat", "dog", "foo", "bar", "cat", "dog", 
"foo", "bar"};
lv.setAdapter(new ArrayAdapter(this, 
android.R.layout.simple_list_item_1, a));
l.addView(lv);

setContentView(l);


This works fine so long as the ListView is the last item in the LinearLayout.
If I move the button or the text below the ListView, the become invisible; the
ListView always extends to the bottom of the screen.

Am I doing something wrong?

Thanks,

Tobiah

[android-developers] Bluetooth API & Device Power Modes

[goosedroid]

The current Bluetooth API documentation does not seem to mention the
behavior of the Bluetooth radio and API when the device goes to sleep.

What should happen in these scenarios?

#1 If the device goes to sleep while connected to a BT device, does
the Bluetooth radio stay on (are connections and streams preserved?)

#2 If no to #1, can a partial wakelock prevent the Bluetooth subsystem
from becoming deactivated?

#3 If yes to #1, will I get a broadcast if the other device drops a
connection and I have registered a BroadcastReceiver listening for
ACL_DISCONNECT?

#4 If the device is asleep, can incoming Bluetooth data on an
established BT connection data wake up the device?

There are probably more such cases I have not considered. Any help
would be welcome.

Yes. Also, questions regarding Twitter (or Facebook, or whatever) are best

Sure and then we end up with crud in the API we can't get rid of.  This is a
pretty trivial widget, and everyone has the source code to it; we aren't
going to junk up the API for this thing.

Re: [android-developers] Re: How to get screen density in pixels-per-inch or equivalent

[Dianne Hackborn]

The density and densityDpi is an abstract density bucket the device
manufacturer has decided makes sense for their UI to run in.  This is what
is used to evaluate things like "dp" units and select and scale bitmaps from
resources.

The xdpi and ydpi are supposed to be the real DPI of the screen...  though
as you've seen, many devices don't set it correctly. :(  This is our fault,
it isn't actually used anywhere in the platform, so people don't realize
they have a bad value, and we haven't had a CTS test to try to make sure it
is sane (it's not clear how that test should work).  Worse, we shipping the
original Droid with a graphics driver that reports the wrong value here...
 in fact that reported that same damnable 96.

Unfortunately, I don't have a good solution if you want to get the real
exactly screen dots per inch.  One thing you could do is compare xdpi/ydpi
with densityDpi and if they are significantly far apart, assume the values
are bad and just fall back on densityDpi as an approximation.  Be careful on
this, because a correctly working device may have densityDpi fairly
different than the real dpi -- for example the Samsung TAB uses high density
even though its screen's really density is a fair amount lower than 240.

Re: [android-developers] Re: HttpURLConnection gives UnknownHostException

[Ankur Avlani]

True, I agree with what you say.  Its just that I feel, other apps should
also break or give error.

Anywayz, Thanks a lot for your inputs.

Ankur.

[android-developers] Re: Particularity running modified standard app

update the manifest package name, and double check the resources for
the string.

You simply missed something.

[android-developers] Re: HttpURLConnection gives UnknownHostException

[Brill Pappin]

Well i suppose thats possible if your messing with the network stack,
but it's pretty low level for Java/Android.
I guess its also possible that the Android version you have has a
crappy stack or driver... or you have rooted it and have been messing
around under the covers so to speak.

There is nothing in Android really that would allow you to mess it up
that badly AFAIK, so I doubt it's your application causing the problem
if your not specifically getting under the covers.

However, the meaning of the exception is clear:
http://download.oracle.com/javase/1.4.2/docs/api/java/net/UnknownHostException.html
and your app doesn't really control the process of translating a
domain to an ip.

[android-developers] BluetoothChat example and unsynchronized write

[goosedroid]

In the BluetoothChat demo (BluetoothChatService), there is a function
which performs an unsynchronized write to the ConnectedThread.write()
function. Its documented this way, so its clear that the developer did
this for a reason ... but I don't understand how this could work
reliably

public void write(byte[] out) {
// Create temporary object
ConnectedThread r;
// Synchronize a copy of the ConnectedThread
synchronized (this) {
if (mState != STATE_CONNECTED) return;
r = mConnectedThread;
}
// Perform the write unsynchronized
r.write(out);
}

ConnectedThead's write is not synchronized in any way.

Does anyone have any ideas?
