[android-developers] Re: Reusable Android library packaging: interest?
I like the idea and as far as I know this is already possible to some extend by using the Maven Android Plugin. However this is really a suboptimal way in terms of component reuse on the device. Ideally it would even go further and get to a stage where a app could declare a dependency to a widget, library, intent or whatever and some central repository would be providing it for download. This would be similar to how e.g maven treats dependencies and downloads them on the fly when needed or even closer to Android how Linux package management systems like apt or rpm handle dependencies. The only problem with this approach is that it requires a strong open source community supporting the distribtution mechanism and at thist age I have my doubts this could be achieved on Android. Would be great though! manfred -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] drawText and drawBitmap start location is different?
I don't recall the exact details in Android, but in almost all graphics APIs the Y position for text is either the [baseline] (bottom of a letter 'o' or 'n') or [baseline + descent] (bottom of the letter 'g' or 'y'). In other words, (x,y) for bitmaps is top-left, (x,y) for text is lower left. A quick experiment would tell you whether it's the baseline or baseline + descent.

[android-developers] help needed in integration of facebook api with android [plz answe my confusion in the sample code given]
Hello experts !
I am trying hard for many days to implement authentication facility in
my app by facebuk login id. I tried with fbconnect api but it wasnt
working. I got this code and tried . It works fine on version 1.6 and
connects to my facebook application. But i just need to ensure if
login is successful then it should return to my local app activity.
if it feels odd understanding the code then here is the link ...
http://forum.developers.facebook.com/viewtopic.php?pid=146956
I am still a beginner and takes a little while to understand code :S
up to my understanding there is a class fConnect created by author
which make http posts requests to facebook api.
Confusions:
1) why is xd_receiver link is required ? its imp to understand because
its used in the onPagestarted() function in facebookwebview client
class in Connection.java. There is an if condition for
page.getPath().equals(/connect/xd_receiver.htm when its true a
session is created and Intent is called for the intended activity in
the application. Thats what i want to do.
Problem:
there is no getsetting() function implemented in the FConnect class :S
if the author has done it i might have been able to run it correctly.
Kindly guide me about working of this function so that i can implement
it myself.

Re: [android-developers] plotting Market sales - determining if your android work is profitable
The script grabs the cookie from an authenticated session with Google Checkout before downloading the purchase records, which requires that the user enter their password. It's probably better that the passwords are not transmitted to my system. To run the script yourself, you just need an Ubuntu installation running somewhere. It's easy enough to set one up - if you don't want to install it on a new partition, you can use Wubi ( http://en.wikipedia.org/wiki/Wubi_%28Ubuntu_installer%29) to install it from Windows, or host an Ubuntu virtual machine inside Windows with VMWare or VirtualBox. I may eventually write an Android app that does the same thing as the script, but the available Python libraries make the task much easier.

[android-developers] Re: Fastest and most reliable Location provider
Bob- You're absolutely right. The phone will continue to be a phone, so the Network listener really isn't an energy consumer as its always connected to towers. Great analysis, thanks! You say simplicity is probably the best approach here--my main goal is to get a location as fast as possible, whether it be network or GPS, then hope we can eventually get a GPS update, but without one it will be OK.. Do you think my approach will be just as fast as running two side-by-side listeners? Ning- This isn't really a concern for me as the lifetime of my app is not very long..

Please let me know your thoughts on this method: Rather than running both listeners side-by-side as John suggested above, I am first running a GPS listener and then within that listener's onProviderDisabled and onStatusChanged [only if the status is OUT_OF_SERVICE or TEMPORARILY_UNAVAILABLE] I am requesting updates from a Network listener [and of course setting a networkOn=true flag so I don't turn it on twice or anything]. Then the Network takes over [while GPS listener remains running] until onStatusChanged() in the GPS listener gets an AVAILABLE status at which point I turn off the Network listener [and mark the flag accordingly] and allow the GPS to do its thing. Apparently, my reply didn't go to the public list because I habitually hit 'a' when I tried to reply all in Google Groups, which does not do the job. I have been using this approach for a while. There are two problems with it. The first one is that GPS takes a while to get the first fix. The second one is power consumption. My program is set to get update every 5 minutes or 200 meters. After a day or so when I checked the battery usage, it had raised to the top of the list, consuming some 30% of all power consumed during that period. So I switched to using network location only, and my program disappeared from the list. So my opinion on this is that unless absolutely necessary, I won't use GPS as location provider frequently. It will drain the battery very fast. -- Ning -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Announcing RoboGuice 1.0
I was thinking about using Guice myself before, but hesitated fearing
to make the overall sluggishness of the platform even worse.
How much of an overhead are talking about in terms of memory footprint
and size of bundled libraries? Any noticeable impacts on speed or
battery life? How often does Guice kick in in the background?
I'm currently stepping back from overly abstract programming models on
Android because of exactly these issues.
On Mar 29, 8:53 pm, Michael Burton m...@niskala.org wrote:
Hello Android developers,
I'd like to announce the final release of RoboGuice 1.0!
http://code.google.com/p/roboguice
RoboGuice is a framework that brings the simplicity and ease of Dependency
Injection to Android, using Google's own Guice library. If you've ever used
Spring (the #1 enterprise framework on Java, now more popular than J2EE
itself) or Guice, you already know how convenient this style of programming
can be.
To give you an idea, take a look at this simple example of a typical Android
activity:
class AndroidWay extends Activity {
TextView name;
ImageView thumbnail;
LocationManager loc;
Drawable icon;
String myName;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
name = (TextView) findViewById(R.id.name);
thumbnail = (ImageView) findViewById(R.id.thumbnail);
loc = (LocationManager)
getSystemService(Activity.LOCATION_SERVICE);
icon = getResources().getDrawable(R.drawable.icon);
myName = getString(R.string.app_name);
name.setText( Hello, + myName );
}
}
This example is 18 lines of code. If you're trying to read through
onCreate(), you have to skip over 5 lines of boilerplate initialization to
find the only one that really matters: name.setText(). And complex
activities can end up with a lot more of this sort of initialization code.
Compare this to the same app, written using RoboGuice:
class RoboWay extends GuiceActivity {
@InjectView(R.id.name) TextView name;
@InjectView(R.id.thumbnail) ImageView thumbnail;
@InjectResource(R.drawable.icon) Drawable icon;
@InjectResource(R.string.app_name) String myName;
@Inject LocationManager loc;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
name.setText( Hello, + myName );
}
}
In this example, onCreate() is much easier to take in at a glance. All the
platform boilerplate is stripped away and you're left with just your own
app's business logic. Do you need a SystemService? Inject one. Do you need
a View or Resource? Inject those, too, and RoboGuice will take care of the
details.
RoboGuice's goal is to make your code be about your app, rather than be about
all the initialization and lifecycle code you typically have to maintain in
Android.
RoboGuice has been in development since August 2009, and 0.9 entered release
candidacy in December and has been stabilizing ever since. After three months
and a few finishing touches, we now believe it's ready to expose to a larger
audience.
We know that RoboGuice won't be for everybody. Although RoboGuice never
prevents you from doing things the Android way, some people will still prefer
seeing everything spelled out explicitly in their code. And other people who
write extremely high performance applications such as games may not want to
incur the small overhead imposed by yet another framework. But for people
who want to build simple and straightforward code that's easily testable and
easy to read, I encourage you to give RoboGuice a try.
We hope you like it. Stop by our discussion forums if you'd like to have any
help getting started.
Cheers,
Mike
PS. We're beginning work on RoboGuice 1.1 now, which will include more
injectible objects, better unit testing support, and hopefully some general
usability improvements as well. I'd love to hear your thoughts on other
things you'd like to see in the next release.

This would mean a lot of unnecessary memory allocation and de-allocation that is likely to hurt your performance on a mobile device. Instead you could have a small pool of Laser objects initialized up front that will be the max number of lasers the user can fire and see on screen at any given time. By default all objects are inactive, or unfired. When the user fires one, you find the first inactive laser and fire it, which means making it active and getting it ready to move along it's path. Once it's hit something or is off screen, it's marked inactive again (destroyed) to be put back in the pool for re-use. You could do this with two lists (active and inactive), moving items back and forth as necessary, or with one list and setting a flag on each laser object indicating it's current state. Just some stuff to think about as you make your game. Hope that helps!

Re: [android-developers] Re: How to refer an attribute value to the other attribute in the same element of layout
adag wrote: Thanks Mark for your reply, But my requirement is little different. basically I am changing listview android:background Color dynamically. As you know that while list gets prepared every time, first it refers to the android:cacheColorHint from the cache to draw the list otherwise the scrolling of list gives a broken color of predefined cache color with black. Therefore I was looking if I can refer the attribute of background to the cacheColorHint then changing the background would not also conflict with the listview background color. Otherwise I can also use getListView().setBackgroundResource(R.Color.light_blue); But I am affraid how to handle the cacheColorHint. getListView().setCacheColorHint is not working in this case. Other than using transparent with android:cacheColorHint. any light Mark would be wonderful. If setCacheColorHint() is not working the way it is documented, write up a sample project demonstrating the problem and post it to http://b.android.com with a description. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _Beginning Android 2_ from Apress Now Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Finish activity
Hi!
I have a problem with my application. During the execution of it, I
have some buttons which execute other activities when I click on them.
The way I am realising it is:
private OnClickListener scaleImage = new OnClickListener()
{
public void onClick(View v)
{
Intent intent = new Intent();
intent.setClass(main.this, Scale.class);
startActivity(intent);
update();
}
};
The other activity finish it execution using the function finish(). I
have a problem. When the activity finish, the function update() should
be executed. However it doesn't run until I click on other button. I
don't know the reason, the function update() is just bellow of
startActivity.
Thank you very much. Regards.

startActivity() is not a blocking call. As your code is written above,
your call to update() happens immediately after you call startActivity().
You may wish to use startActivityForResult(), so you can be notified via
onActivityResult() when then other activity has finish()-ed, and you can
call update() then. Or, depending on what update() does, you might
consider just putting that call in onStart() or onResume(), so you
update every time your activity comes back to the foreground.

[android-developers] Re: Displays on emulator, not on phone

the GPS was off :)
LocationManager.GPS_PROVIDER is supposed to use whatever location

To address that I have it check if the gps is on and use network if
the gps is disabled.
LocationManager locm = (LocationManager)

//Check if GPS is enabled and choose network if it isn't

locm.requestLocationUpdates(network, 0, 0,onLocationChange);

Another suggestion: don't use network and gps, but use
LocationManager.NETWORK_PROVIDER and LocationManager.GPS_PROVIDER instead.

No, LocationManager.GPS_PROVIDER, presently, has a value of gps. It's more that, in case for some crazy reason they change that convention, your code will be less likely to break using LocationManager.GPS_PROVIDER than gps, because they'll change LocationManager.GPS_PROVIDER to match the new convention. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Warescription: Three Android Books, Plus Updates, One Low Price! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Service Object Availability between Activities
I have a Connection object that is instantiated by the

Connection object and get information from a controller over TCP/IP.
Again, I launch the service from a splash screen with success. I bind
to the service in my main activity and can access it's objects(i.e.
Connection) successfully.
Then once I start a new activity from the main activity, I am able to
successfully bind to the service. However, when I try to access the

I would like to be able to connect to the object from multiple

[android-developers] Re: Changing AlertDialog font size
Thank you Mark,
Worked not like a charm at all, but work non the less :D
I found it awfully complicated and not very well documented just to
set a font size, or a layout.
The setAdapter seems to be pretty powerful although I'm not sure I
understood everything.
For future reference, in the onCreateDialog of an Activity :
---
final CharSequence[] itemsMark =
{getResources().getString(R.string.Mark_As_Beautiful),
getResources().getString(R.string.Mark_As_Fun),
getResources().getString(R.string.Mark_As_Not_A_Portrait),
getResources().getString(R.string.Mark_As_Offensive),
getResources().getString(R.string.Mark_As_Spam),
getResources().getString(R.string.Mark_As_Cancel)
};
ArrayAdapterCharSequence itemsAdapter = new
ArrayAdapterCharSequence (this,
R.layout.menu_items, itemsMark);
builder = new AlertDialog.Builder(this);
builder.setTitle(My Title);
builder.setIcon(R.drawable.icon);
builder.setAdapter(itemsAdapter, new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int item) {
switch(item) {
case 0:
//Mark as Beautiful
break;
case 1:
//Mark as Beautiful
break;
case 2: //Mark as Not a Portrait
break;
case 3:
//Mark as Offensive
break;
case 4:
//Mark as Spam
break;
case 5:
//cancel
break;
}
}
});
And in my layout/menu_items.xml :
TextView xmlns:android=http://schemas.android.com/apk/res/android;
android:id=@android:id/text1
android:layout_width=fill_parent
android:layout_height=wrap_content
android:padding=10dip
android:layout_margin=5dip
android:gravity=center_vertical
android:textSize=22dip
android:textColor=#ff00
android:typeface=normal
android:lineSpacingExtra=0dip/
Anyway, I stopped trying to do something fancy, regular black on white
labels with default pressed state and I'm good to go.
Thanks again.
Yahel

Dmitri, thanks for this. You might be right-- the user indicated an
HTC app (not Android, per se) did this sync for him. I think I may
offer an option for including ALL contacts with a simple textual
filter on their display name in an effort to weed out the filth. This
alternative mode would support people like this guy, I hope.

Hi Tone,
This was before my time, but I think you are doing it right. As far as I
remember, Android 1.5/6 did not support any kind of integration with
Outlook. Whatever mechanism was used to import the Outlook contacts must
have messed them up. On Android 1.5/6, when you were adding a contact, you
were supposed to add it to the MyContacts group explicitly. So reading the
MyContacts group should give you all _correctly_ imported contacts and
filter out those automatically added by Gmail.

contacts.
Why is this so under-documented, with access provided through textual
URIs and database calls?
Can someone show me a definitive code blurb that gets all the contacts
in the Android contact panel and NOT those crufty pretend contacts?
Thanks in advance.

[android-developers] Re: Activating Bluetooth
Ok... it's ugly. Indeed, this was one of the things I found difficult
to do in the same manner in Android 1.x and Android 2.x
I actually found it difficult to have one app exercise both these
interfaces, one of the several reasons I wish I had a separate app for
1.x vs 2.x -- if you've not yet made a final choice there, split them
up and you will be happier.
In Android 1.x, this will do it, cribbed and reduced from Android
source.
I had to bring over a considerable portion of android.bluetooth to get
this working.
You would call the static enable() function to do it:
import android.bluetooth.BluetoothDevice;
import android.content.Context;
public class LocalBluetoothManager {
private static LocalBluetoothManager sSingleton;
/** Used when obtaining a reference to the singleton instance. */
private static Object INSTANCE_LOCK = new Object();
private boolean mInitialized;
private BluetoothDevice mManager;
public static boolean enable(Context context, boolean b) {
synchronized (INSTANCE_LOCK) {
if (sSingleton == null) {
sSingleton = new LocalBluetoothManager();
}
if (!sSingleton.init(context)) {
return false;
}
return b ? sSingleton.mManager.enable() :
sSingleton.mManager.disable();
}
}
private boolean init(Context context) {
if (mInitialized) return true;
mInitialized = true;
mManager = (BluetoothDevice)
context.getSystemService(bluetooth); //
Context.BLUETOOTH_SERVICE);
if (mManager == null) {
return false;
}
return true;
}
}
In Android 2.x, it is simpler:
import android.bluetooth.BluetoothAdapter;
BluetoothAdapter adapt = BluetoothAdapter.getDefaultAdapter();
adapt.enable(); // or adapt.disable();
You MAY need to have these permissions in your manifest:
uses-permission android:name=android.permission.BLUETOOTH /
uses-permission
android:name=android.permission.BLUETOOTH_ADMIN /
Make sure you test on both Android 1.x and 2.x before going to Market.

[android-developers] Re: Fastest and most reliable Location provider
There are competing parameters in a location fix: Availability, Speed and accuracy. You'll have to determine what level of accuracy is acceptable before you can decide which fix you want to use. I've seen network location fixes with 10,000 meter accuracy, is that good enough for your application? If the user is on WiFi and indoors, you won't get much of a fix at all but you won't even know the availability of GPS until at 30 seconds or more have passed. -John Coryat -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Moving a graphic on different screen sizes with the right ratio?
Hello, I tracked the behaviour of the different screen sizes when I increased the position of a graphic by 10 pixel. Unfortunately happened what I already thought. When the display is bigger, I'm able move a graphic a lot of times more to get to the bottom of the screen. So the ratio between the graphic and its environment is not correct anymore (so not 10 pixel as on normal screen) although the change of the graphic on the different screens looks correct (On big screen it is bigger, on small screens it is smaller). When I move the graphic from the top of the screen to the bottom, I can move that on 480x800 about 65 times, on 480x854 70 times, and on the 320x480 screen only about 25 times. So the target must be to calculate the right ratio so that 10 pixels on the small screen are 17 pixel (or sth. similar) on big screens. What approaches do I have to do that? I already thought about getting the value of res.getConfiguration().screenLayout to know if I have a small, normal, or big size to be able to calculate anyhow the right ratio, but this both seems to be pretty cumbersome and moreover I get values from res.getConfiguration().screenLayout I can't explain. I launched 6 emulator instances and got the following values from res.getConfiguration().screenLayout: 240x320 QVGA low density: 17 320x480 HVGA medium density: 18 480x854 WVGA high density: 34 480x800 WVGA high density: 34 240x400 WQVGA low density: 34 240x432 WQVGA low density: 266435490 (yes, I really get this value!) This approach seems to be useless because I cannot even distinguish between 480x854 and 480x800, much less of the last value which seems to be corrupt. How can I solve it to move a graphic on the different screens with the right ratio? How do game developers solve this when they support all screens?

[android-developers] Where do the resources from android.R come from?
I'm trying to understand the whole android.R structure, and it would be nice if I knew where the source of those resources is. I assume that, like the R object in my own project, it is built from a resources directory somewhere on my system. That directory should contain the drawables, layouts, values and whatever other files are used to create this object. But I'm not sure where to find it. I thought that I had found it when I went to /usr/lib/android-sdk- linux_86 (where I have the SDK installed on my computer), and found the platforms directory. In that path, there is a directory for each platform installed in the SDK, and under each of those directories there is a data/res directory that contains drawables, layouts, etc. But the contents of those directories don't match what is available in the android.R object while I am developing. For example, under android-1.6/data/res/drawables, I see the following dialog icon images: ic_dialog_alert.png ic_dialog_dialer.png ic_dialog_email.png ic_dialog_info.png ic_dialog_map.png ic_dialog_menu_generic.png ic_dialog_time.png ic_dialog_usb.png But the only android.R drawables available to me in my applications are: ic_dialog_alert.png ic_dialog_dialer.png ic_dialog_email.png ic_dialog_info.png ic_dialog_map.png Does anyone know what's going on?

[android-developers] crash in Android SMS code

This is on a T-Mobile MyTouch running 1.6. I made sure I'm not sending
any null parameters. Here's the code in SmsMessage.java that it
crashes at:
public static class SubmitPdu extends SubmitPduBase {
}
The crash is in the Android platform, but I'm guessing that I'm using
it wrong, so I'm asking here. Why would init croak? Thanks in
advance for your insight.

[android-developers] Re: intensive writing to internal memory
Thanks Bob and Dianne, The issue is that I have no choice but do a lot of writing since this is a research app that constantly logs phone and user activity over many months... We are dealing ok with battery and processing power (we only write every several minutes), and the main concern remains the Flash lifetime. We are working with cyclic log files (that roll over every several hours), and have already found a way to move our older files to the SD card. However our current dilemma is whether to do all writing on the SD-card, or keep the current open file on the main memory, and copy it to SD when moving to the next log file. The problem of doing everything on the SD card is that when a user mounts the card to a PC, we can't access it for logging and other tasks, and that leads to various crashes and issues, so I thought it might be simpler if we work with the current file on the main memory, but I fear the Flash degradation... I'm willing to buy new SD cards every few months, but I really don't want to mess up the phone itself! On Apr 4, 2:27 am, Dianne Hackborn hack...@android.com wrote: If you are talking about internal storage (not RAM memory), then yes this is generally flash memory, and you want to be careful about how much you write to it for numerous reasons: also extremely important are the battery impact (writing to flash is expensive) and performance (causing other things that are accessing flash storage to be blocked by what you are doing). That said, properly designed flash storage won't let you write to the same block over and over. Writes are spread across the flash storage just to avoid that kind of issue.

[android-developers] AudioTrack in streaming mode
Hi everyone, I need to modify the volume of an AudioTrack, while it is
playing a sound in streaming mode.
I have something like this:
minBufSize=AudioTrack.getMinBufferSize(11025,
AudioFormat.CHANNEL_OUT_STEREO, AudioFormat.ENCODING_PCM_16BIT);
fSound=new AudioTrack(
AudioManager.STREAM_MUSIC,
11025,
AudioFormat.CHANNEL_OUT_STEREO,
AudioFormat.ENCODING_PCM_16BIT,
minBufSize,
AudioTrack.MODE_STREAM
);
sample=this.getApplicationContext().getResources().openRawResource(R.raw.longfart);
b=new byte[minBufSize];
fSound.play();
fSound.setPlaybackRate(11025/2 + 11025*(yPos+187)/(2*187));
fSound.setStereoVolume( volume, volume);
try {
c=sample.read(b, 0, b.length);
} catch (IOException e1) {
}
while(c!=-1){
fSound.write(b, 0, c);
try {
c=sample.read(b, 0,
b.length);
} catch (IOException e) {
}
}
This works ok and plays the whole song (it's just a few seconds).
What I want to do is allow the user to change the volume while the
stream is being played. Can it be done?

[android-developers] Forcing the Symbols Soft Keyboard
I have an EditText that specifies android:digits where all the specified characters are on the standard symbols soft keyboard. Unfortunately it seems that just using android:digits is enough to always cause the qwerty keyboard to pop up. Always having to press the 123? key for that one EditText is a bit inconvenient for my users and, sad to say, it's a difficult concept for a few.

[android-developers] Re: Fastest and most reliable Location provider
I should have said to opt for the simplest thing that actually works! Or, to put it another way, as simple as possible, but no simpler. (Neither phrase is mine, but I can't recall the correct attributions.) For the fastest result, I'd start off with both listeners. The network will nearly always win (unless you're off the grid), but the GPS won't start until you ask it to. However, even if you can't get a network fix, you MAY be able to get a GPS fix, eventually. It will certainly take longer in this case. I haven't tested it in a location far enough away from towers to not get any network fix at all, and it would vary by phone anyway, but in theory it should be possible. Handling this case may not be important. A long-delayed GPS fix may be useless, for example. So as Maps API Guru says, you'll have to decide. On Apr 4, 3:00 am, patbenatar patbena...@gmail.com wrote: Bob- You're absolutely right. The phone will continue to be a phone, so the Network listener really isn't an energy consumer as its always connected to towers. Great analysis, thanks! You say simplicity is probably the best approach here--my main goal is to get a location as fast as possible, whether it be network or GPS, then hope we can eventually get a GPS update, but without one it will be OK.. Do you think my approach will be just as fast as running two side-by-side listeners? Ning- This isn't really a concern for me as the lifetime of my app is not very long..

Please let me know your thoughts on this method: Rather than running both listeners side-by-side as John suggested above, I am first running a GPS listener and then within that listener's onProviderDisabled and onStatusChanged [only if the status is OUT_OF_SERVICE or TEMPORARILY_UNAVAILABLE] I am requesting updates from a Network listener [and of course setting a networkOn=true flag so I don't turn it on twice or anything]. Then the Network takes over [while GPS listener remains running] until onStatusChanged() in the GPS listener gets an AVAILABLE status at which point I turn off the Network listener [and mark the flag accordingly] and allow the GPS to do its thing. Apparently, my reply didn't go to the public list because I habitually hit 'a' when I tried to reply all in Google Groups, which does not do the job. I have been using this approach for a while. There are two problems with it. The first one is that GPS takes a while to get the first fix. The second one is power consumption. My program is set to get update every 5 minutes or 200 meters. After a day or so when I checked the battery usage, it had raised to the top of the list, consuming some 30% of all power consumed during that period. So I switched to using network location only, and my program disappeared from the list. So my opinion on this is that unless absolutely necessary, I won't use GPS as location provider frequently.

[android-developers] Auto-centering and auto-clipping TextView background?
Is there a way to tell Android to do the following when setting the background image for a TextView? 1. Scale the image so that it's just large enough to fill the the entire viewing area without any black borders, while still maintaining its aspect ratio. This might require clipping once the image is actually displayed, but that's OK (read on). 2. Then, center the image in the viewing area, both horizontally and vertically. 3. Finally, clip the image to the size of the viewing area, without any further rescaling. I'm guessing that this kind of image processing is not automatically done via any of Android's facilities, and that I'll have to do it myself. If this is a correct assumption, could someone point me to some documentation or some examples which could explain how I can accomplish this? I'm guessing that I'll have to subclass my TextView and implement my own onDraw() method, but could someone confirm or deny that assumption?

[android-developers] Re: intensive writing to internal memory
If Jason's suggestion of pushing it to a server is inadequate, you can buffer events, and only write them out once a minute or 10 minutes or something. This will put an upper bound on the number of writes performed. You can combine the approaches, and push to the server, and only write to the filesystem if you don't succeed in pushing to the server within a decent interval. Then when communications is reestablished, push the saved data up first. You could also send it to the SD -- and when the SD is not available, buffer it on the local filesystem until it becomes available again. Essentially, we're looking at a 3-level buffering hierarchy -- RAM, local flash, and either SD or server. The more the buffering in RAM, the more data you risk losing in the event of a crash, but the fewer writes and less battery required.

[android-developers] Re: Moving a graphic on different screen sizes with the right ratio?
That field is documented as being a bit mask: http://developer.android.com/intl/fr/reference/android/content/res/Configuration.html#screenLayout That means that it is one number, but different bits within the number are being used to indicate different things. To check any particular thing about it you can perform an and operation on it using the mask of the part you want, then compare to the constants. It sounds like you'd be better off in general using the equivalent of density independent pixels anyway. Multiply your pixel measurements by the density field in DisplayMetrics: http://developer.android.com/intl/fr/reference/android/util/DisplayMetrics.html#density And you'll get the same number as if you used dip: http://developer.android.com/intl/fr/guide/practices/screens_support.html It is also easy to check the width and height of the display in pixels: http://developer.android.com/intl/fr/reference/android/util/DisplayMetrics.html#heightPixels If you wanted to cross the screen vertically in the same number of steps no matter what the height, the number of pixels needed per step for any particular height is easy to calculate. If you are writing a game using GLSurfaceView you don't even have to get the display size yourself, it is passed to you: http://developer.android.com/intl/fr/reference/android/opengl/GLSurfaceView.Renderer.html#onSurfaceChanged%28javax.microedition.khronos.opengles.GL10,%20int,%20int%29 On Apr 4, 1:13 pm, Bevor andr...@pithax.net wrote: Hello, I tracked the behaviour of the different screen sizes when I increased the position of a graphic by 10 pixel.

So the ratio between the graphic and its environment is not correct anymore (so not 10 pixel as on normal screen) although the change of the graphic on the different screens looks correct (On big screen it is bigger, on small screens it is smaller). When I move the graphic from the top of the screen to the bottom, I can move that on 480x800 about 65 times, on 480x854 70 times, and on the 320x480 screen only about 25 times. So the target must be to calculate the right ratio so that 10 pixels on the small screen are 17 pixel (or sth. similar) on big screens. What approaches do I have to do that? I already thought about getting the value of res.getConfiguration().screenLayout to know if I have a small, normal, or big size to be able to calculate anyhow the right ratio, but this both seems to be pretty cumbersome and moreover I get values from res.getConfiguration().screenLayout I can't explain.

trying to switch and let the Intent store the file where it wants but
I can't figure out how to recover the URI where it is saved to. The
docs say this:
The caller may pass in an extra EXTRA_OUTPUT to control where the
video is written. If EXTRA_OUTPUT is not present the video will be
written to the standard location for videos, and the Uri of that
location will be returned in the data field of the Uri.
But what is the data field of the Uri?
Thanks!

[android-developers] Motorola Droid - white balance issues
Howdy all, I've developed a camera-based app, but am experiencing apparent white balance (over balance?) issues on Motorola Droid. I'm using previews and auto-focus before taking the picture - with takePicture() being called from a thread within onAutoFocus(). If I pass the camera in front of a brightly lit scene it begins to alternate between taking an extremely bright (if not solid white image) and a quite dark image. What's going on? Anybody have any ideas? Thanks! -Chad P.S. Thanks Google for the device seeding program =] -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] App released but only tested using the emulator. Could you please test it to me?
Hi all, After spending some time learning about Android´s SDK I´ve finally finished a first version of my first app: a metronome. It´s a simple app but I´ve faced some problems with AudioTrack, most trying to syncronize the audio with changes on the UI. In the end I did all my tests using the Android Emulator (1.6 and 2.1) since I don ´t have an Android device right now. I´ve posted this first version on some sites to get an initial feedback about it: how it works, how is the syncronization between audio and UI, how easy it is to understand the UI, if it´s stable, etc. I would appreciate if you could give me some feedback: https://slideme.org/application/mobile-metronome http://andappstore.com/AndroidApplications/apps/Mobile_Metronome I will post it on Android market as soon as I confirm it´s stable and working properly.

[android-developers] Multiple Listviews in single Activity?
Hi, I want to have multiple listviews in single activity. But only one listview should be displayed at one time. The listviews will be loaded dynamically. So, how can I fill all the four listviews at the same time and display only one. If anyone knows the solution then please share it over here. I hope to get a quick response.

Make sure that your onCreate method is called, and it is not resumed.
You can put some Log statements to check this in your onCreate method.

[android-developers] Re: Reusable Android library packaging: interest?
Hello Mark, You are absolutely right: support for reusable components other than pure Java code (and Java resources) is sorely missed. I personally think Google should step up and add this kind of support to the Android eclipse plugin. In my opinion, the problem of lack of tool support is minor when batch packaging. Using ant it is easy to copy the content of third party libraries. Of course a lack of standards does mean that no viable marketplace for this kind of reusable Android components can emerge. I believe the real problem lies when developing in-house libraries for multiple applications. As maybe 98% or more of the developers use eclipse (just guestimating), eclipse support for reusable (in-house) components is a must for getting this concept off the ground (imho). When developing your own components is easy (just being able add the library Android project as a dependency to your application project, and not having to worry about resources etc.), a need to package and distribute library projects for external use will surely emerge. Ant can actually fill in most of this need already, although a standardised format and automatic dependency resolving (maven?) will surely help. Anyway, if you choose to go the parcel shell route, don't forget a parcel upgrade command. Personally, If I cannot upgrade easily to a new version of a library I wouldn't use it. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: In process communication
Fyi this approach is illustrated in the LocalService sample code.

Kumar's method might work, but you should look up
Context.bindService() and ServiceConnection.onServiceConnected()
to find out how to do this within Android's framework.
What I do: In MyApplication's
@Override public void onStart()
I call:
bindService(new Intent(MyApplication.this, MyService.class),
new (MyServiceConnection(this)),
BIND_AUTO_CREATE);
MyServiceConnection implements ServiceConnection, and as soon as the
service is created or bound, you get a call to
MyServiceConnection.onServiceConnected(), which you implement like
this:
public void onServiceConnected(ComponentName name, IBinder service) {
serv = ((MyService.LocalBinder)service).getService();
}
With serv being an instance variable of MyApplication of type
MyService which you can use to call methods of your Service. Hope this
helps.

Hi @all,
I have a design problem with my Android components.
My activity is starting a service which is doing the work in the
background. What I want is that the service informs the activity about
state changes. How can I do this?
Normally I would add an observer but the activity has no reference to
the service. Then I was thinking to take AIDL but this is more for
inter-process communication.
How is it possible that the service informs the activity about state
changes? Both are running in the same process. What can you recommend?
Thank you in advance.

[android-developers] drawText and drawBitmap start location is different?
Hi all, I want to draw a text on top of a bitmap. So in my onDraw function, i do the following: canvas.drawBitmap(myBitmap, 30, 30, mPaint); textPaint.setTextSize(20); canvas.drawText(Life X 3, 30, 30, textPaint); However, it ended up that the text is above the bitmap. (the X position is correct, but the y position is not). Can anyone help me with this?

Re: [android-developers] intensive writing to internal memory
If you are talking about internal storage (not RAM memory), then yes this is generally flash memory, and you want to be careful about how much you write to it for numerous reasons: also extremely important are the battery impact (writing to flash is expensive) and performance (causing other things that are accessing flash storage to be blocked by what you are doing). That said, properly designed flash storage won't let you write to the same block over and over. Writes are spread across the flash storage just to avoid that kind of issue.

I wouldn't want to damage the phone's memory in a permanent way I'm also not sure if the issue is related to reading writing to the same physical block (the guy was using a single log file and kept appending it, so he was constantly accessing the file's header block), and whether writing cyclic log files might remedy a problem like this..
