[android-developers] How to load a bitmap to a server directly?
Hi there, I've followed this link and I know how to upload a file to a server: http://www.anddev.org/upload_files_to_web_server-t443-s30.html However, let's say I've a Bitmap that I've received from the web, and I want to upload it to a server. Is there any ways to upload the Bitmap directly without first saving it as a file? Based on the link above, I think I just need to get the FileInputStream from the Bitmap. But I don't know how ...

10x Vikram. I've forgot to set the permissions :(. now it works with

'test' and dragged it into /data/misc/location. it returns now :

Tele Atlas has a good demo for this
athttp://developerlink.teleatlas.com/pages/208_sample_applications.cfm
If you're not interested in their registration process, you need
to
get the LocationManager
LocationManager locationManager =
(LocationManager)getSystemService(Context.LOCATION_SERVICE);
and you can pull your LocationProvider from that. Then you need to
requestUpdates on the LocationManager using your
LocationProvider, and
an extended IntentReceiver that overrides onReceiveIntent. The
onReceiveIntent method gets an Intent as a parameter - you can do
Location location = (Location)intent.getExtra(location);
to get your Location.
If you want to draw an icon at the Location you will probably also
want to check out com.google.android.maps.Overlay.
Hope that helps.

try this
adb push /your path/test /data/misc/location/test/test

[android-developers] Re: Intent Receiver for android.intent.action.INSERT
The android.intent.action.INSERT and android.intent.action.VIEW
actions are not broadcasts, they are actions for starting activities
to show a UI to insert a new entry, or view an existing entry,
respectively. Thus you don't register for them with a receiver, you
launch them with startActivity(). (You can also write your own
activity implementing those actions to replace the standard UI, but
that's probably not what you are wanting.)

[android-developers] Re: How to load a bitmap to a server directly?
So, it sounds like you have a Bitmap object. I assume you have some
server (http maybe?) set up to upload it to. Here's some code I use
for doing this:
HttpClient client = new HttpClient();
PostMethod method = new PostMethod(http://your_server/path/to/upload/
script);
Part[] parts = {
new FilePart(pictureFile, new
ByteArrayPartSource(pictureFile,
getBytes(bitmap))),
};
method.setRequestEntity(new MultipartRequestEntity(parts,
method.getParams()));
client.executeMethod(method);
response = method.getResponseBodyAsString();
method.releaseConnection();
And getBytes(Bitmap):
ByteArrayOutputStream output = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 80, output);
return output.toByteArray();

[android-developers] Re: Garbage collector using huge amount of cpu time?
If you don't have a debugger attached (I'm not sure how that might change the behavior), this most likely means your application is creating lots of temporary objects: almost 15,000 every 7 seconds. I'm not aware of any bugs in the system that could cause an application process to start doing this without being due to the application itself, though of course there may be something. Note that in Java it is really really easy to churn through lots of temporary objects, especially with autoboxing and such; this is one of the things you need to be careful about when programming for a mobile device.

[android-developers] Question about Activity.onStop()
Suppose Activity A is running. Then I called startActivity() from
another process which start Activity B. Then normally A.stop() will be
called. But if I write Activity B like this:
class B extends Activity{
public void onCreate(Bundle ...){
super.onCreate(...);
finish();
}
}
which means B finish itself once it was created. Then I noticed
A.stop() won't be called.
My question is:
1. Is it for sure A.stop() won't be called in this condition?
2. At after what step of B(B.onResume()? B.onStart()?) will A.stop()
be called? Is there any step sequence for certain?
Thanks.

[android-developers] Re: Good example for showing exchanging of data mostly arrays or non premitive data types,objects
Hi Raja, I think the following thread provides good info (although it's become a bit long): http://groups.google.com/group/android-developers/browse_thread/thread/9632cb52888ef6db/9287a1a6a24ea577 Assuming you want to pass Objects between Activities in the *same* application (i.e. same process), I believe that passing the Object reference is better than Parceling it using the Intent Extras mechanism (passing a pointer is obviously more efficient than parceling/unparceling an object). If the objects you are passing are relatively lightweight and few in numbers - the performance difference is probably negligible. If you want 2 activities to manipulate the *same* object and not 2 different copies of the same object - then you have to pass an object reference between activities. I faced this problem pretty early in my development effort, and came up with the following mechanism: I created a class called ReferencePasser that wraps a HashMap of Objects, with Long keys. I have an instance of ReferencePasser available to all Activities (as a public static field somewhere, or through the Application object). When an activity wants to pass an object to another activity, it adds the object to ReferencePasser and gets a long key as a result. It then passes this object key to the activity it is starting as an extra, using some agreed-upon String key. When the called activity is created, it retrieves the object key from its intent extras, and gets the object reference from reference passer. It can then remove the object from ReferencePasser to keep its Map small. This approach has been working great for me so far, although obviously it is limited to a single application process. I'll attach sample code in the next thread. Hope this helps, Amos --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Good example for showing exchanging of data mostly arrays or non premitive data types,objects
Here is the sample code for passing Object references between
activities:
I have a class called ReferencePasser, which wraps a HashMap:
import java.util.HashMap;
/**
* @author Amos
* Maps Objects to keys.
* The keys are generated automatically on insertion (based on a
running index).
* Useful for passing references to objects.
*/
public class ReferencePasser {
private HashMapLong, Object _objects;
private long _nextKey;
public ReferencePasser() {
_objects = new HashMapLong, Object();
_nextKey = 1;
}
/**
* Adds the given object to the map.
* @param o
* @return the key of object inserted.
*/
public long put(Object o) {
long key = _nextKey++;
_objects.put(Long.valueOf(key), o);
return key;
}
/**
* @param key
* @return the object with the given key, or null if
key doesn't
exist in
* the map.
*/
public Object get(long key) {
return _objects.get(Long.valueOf(key));
}
/**
* Removes the object mapped to the given key from the
map.
* @param key
*/
public void remove(long key) {
_objects.remove(Long.valueOf(key));
}
}
Access to a single instance of ReferencePasser is achived through this
class:
public class GlobalStuff {
private static ReferencePasser _passer;
/**
* Returns the application's ReferencePasser, which is
useful for
passing
* references to complex objects between Activities
and/or
Services.
* @return
*/
public static ReferencePasser getReferencePasser() {
if (_passer == null)
_passer = new ReferencePasser();
return _passer;
}
}
Here's a sample for an activity that wants to send an object to
another activity:
public class SourceActivity extends Activity {
...
private void startTargetActivity(SomeObject myObject) {
ReferencePasser passer =
GlobalStuff.getReferencePasser();
long objectKey = passer.put(myObject);
Intent intent = new Intent(this,
TargetActivity.class);
intent.putExtra(com.myapp.blabla, objectKey);
startActivity(intent);
}
...
}
And here's how the called activity gets the object that was passed to
it:
public class SourceActivity extends Activity {
protected void onCreate(Bundle icicle) {
//remember to handle null values, which I don't
do here
long objectKey =
getIntent().getLongExtra(com.myapp.blabla, 0);
ReferencePasser passer =
GlobalStuff.getReferencePasser();
SomeObject passedObject = (SomeObject)
passer.get(objectKey);
passer.remove(objectKey) //if I don't need the
object reference
anymore
...
}
...
}

netstat reports):
private void test() {
for (int i = 0; i 1; i++) {
try {
String urlStr = http://test-url.com/?q=; + i;
URL url = new URL(urlStr);
InputStream is = url.openStream();
byte[] buffer = new byte[1024];
int len = is.read(buffer);
String content = ;
while (len != -1) {
content += new String(buffer, 0, len);
len = is.read(buffer);
}
is.close();
} catch (Exception e) {
Log.w(TAG,e);
}
Log.i(TAG, i: + i);
}
}
As a consequence, no more sockets can be opened after a while. The
problem does not seem to occur when running the same code in a
normal java program (i.e. not in android). Am I missing something
here? Or is this problem due to a bug in android? How could I read
many URLs without running into this problem? (I want to query a web
service with lots of different parameters, that's why I need to open
that many connections.)
By the way: The problem only occurs, if the urlStr changes in each
loop.
Thanks for any hints,
Michael

[android-developers] Re: Intent Receiver for android.intent.action.INSERT
If you want to write your own activity implementing those actions, how
would you do that ?
Implementing a new whole ContactsProvider ?
If you only want to replace, say INSERT ?
How your new ContactsProvider can coexist with the standard one if you
want to extend its functionality ?

The android.intent.action.INSERT and android.intent.action.VIEW
actions are not broadcasts, they are actions for starting activities
to show a UI to insert a new entry, or view an existing entry,
respectively. Thus you don't register for them with a receiver, you
launch them with startActivity(). (You can also write your own
activity implementing those actions to replace the standard UI, but
that's probably not what you are wanting.)

[android-developers] How to associate my App with a file extension in the Browser
Hi, I would like to implement the following scenario: When a user browses a web page with Browser and clicks a link with a special file extension (which is unique to my application, such as www.mysite.com/somefile.xxx), that file will be downloaded and then my application launched to view the downloaded file. I'd like the browser to handle the file download if possible, and when it's done start one of my activities and provide the file to it. This is desktop behavior and I'm not sure it conforms to the Android intent/content provider way of doing things - but this is what I'd like to happen. Any ideas or pointers?

[android-developers] Re: Polling internet, battery life Suggestion / Question?
Your idea sounds very useful. Indeed, it could be an idea that would fit well into our project OpenIntents. I already suggested it as an idea in our project group: http://groups.google.com/group/openintents/browse_frm/thread/7f34fe99bd23c25 linking back to this discussion here, so feel free to add any additional information there as well. As of the real savings, I'm not so sure. Google seems to promote always-on-networking, so the connection cost should not matter as it would be a flatrate. As for saving battery, one still has to transmit a certain amount of data, so whether I transmit 3 minutes out of 15 minutes in a row, or 3 times 1 minute within 15 minutes does not obviously seem to make a large difference in battery savings. I imagine, there could be some savings if all services polled exactly at the same time in parallel (to fill waiting gaps for individual services) that could reduce the time say from 3 minutes for 3 services to 1 1/2 minutes for 3 services, so the phone could sleep for 13 1/2 minutes which would make sense.

(http://groups.google.com/group/android-developers/search?group=androi... ). Lots of people are going to write apps that poll server. Each one will need configuration on how often to poll. And user will have to configure in each app. If he configures every 15 min in 3 different apps and each start poll at a different point in time he will be connecting to the internet thrice every 15 min. Not nice. Suggestion 1. Set up a Internet polling mechanism for polling the internet defaulting to every fifteen minutes. User can change this setting in one place. Allow services / apps to subscribe to this service. IPM(Internet polling mechanism) wakes up one service at a time. service polls internet does whatever it wants and goes back to sleep. Now each app has to initiate a connection and close it, which from my very basic understanding will slowdown the whole process and again drain battery. Instead IPM opens a socket and hands socket to each service round robin fashion. Service only indicates done. When all subscribers done IPM closes down connection.

[android-developers] Re: Question regarding MapActivity / MapView
It just doesn't work. I see the directory and the files in the file
explorer and when i browse with the adb shell, but android doesn't see
the 'test' folder as a location provider, although it has exactly the
same files as the 'gps' folder. I tried another trick. I've removed
the files in the gps and replaced them with my own files, but when I
run I still get the default location in St. Francisco, instead of my
own in Germany. It seems that android ignores my updates of the /data/
misc/location folder.

and you can pull your LocationProvider from that. Then you need
to
requestUpdates on the LocationManager using your

an extended IntentReceiver that overrides onReceiveIntent. The

do

[android-developers] Re: Good example for showing exchanging of data mostly arrays or non premitive data types,objects
Hi Amos,
Thank you for the code libary to put and get java object refereces
across the components (i.e activities).
Based on hackbod comments, I am still not confused, why one has to do
so much for passing references, it is my intent is to pass them by
refence and the underllaying framework should manage this irrespective
of cross components, cross process etc.. I also hate impl. interfaces
such as Serialisable,parcelble etc..at least in this context as it is
one device and that to mobile device. I am sure having framework take
care of this would enable better memory and shortens the programing
logic.

on a
running index).
* Useful for passing references to objects.

}
/**
* Removes the object mapped to the given key from
the map.
* @param key
*/
public void remove(long key) {
_objects.remove(Long.valueOf(key));

Access to a single instance of ReferencePasser is achived through this
class:
public class GlobalStuff {
private static ReferencePasser _passer;
/**

is useful for
passing

and/or
Services.
* @return
*/
public static ReferencePasser getReferencePasser() {
if (_passer == null)
_passer = new ReferencePasser();
return _passer;
}
}
Here's a sample for an activity that wants to send an object to
another activity:
public class SourceActivity extends Activity {
...
private void startTargetActivity(SomeObject myObject)
{
ReferencePasser passer =
GlobalStuff.getReferencePasser();
long objectKey = passer.put(myObject);
Intent intent = new Intent(this,
TargetActivity.class);
intent.putExtra(com.myapp.blabla,
objectKey);
startActivity(intent);
}
...
}
And here's how the called activity gets the object that was passed to
it:
public class SourceActivity extends Activity {
protected void onCreate(Bundle icicle) {
//remember to handle null values, which I
don't do here
long objectKey =
getIntent().getLongExtra(com.myapp.blabla, 0);
ReferencePasser passer =
GlobalStuff.getReferencePasser();
SomeObject passedObject = (SomeObject)
passer.get(objectKey);
passer.remove(objectKey) //if I don't need
the object reference
anymore

[android-developers] What is Android? diagram in docs.
Hi, My question is a little silly one, but I wonder why on diagram at http://code.google.com/android/what-is-android.html the Android Runtime layer is not between Application Framework and Libraries? Is this because Android Runtime uses kernel's functionality for threading and low-level memory management? So why this Runtime layer is not touching the Linux Kernel on this diagram? Don't get me wrong, I'm not trying to critisize this.

[android-developers] Re: What is Android? diagram in docs.
I guess. Runtime is fundamentally on the side. Think of runtime as the CPU for code written in Java: apps use the runtime directly, java framework libraries use the runtime directly. Diagram would be better if runtime went to top all the way. JNI allows to go directly from application framework to libraries without going through runtime. Runtime doesn't work directly with kernel (would be very unusual), probably goes through libc, kernel interface is specific to CPU and not portable.

[android-developers] Re: Picture and Buttons for different screen size
Thanks, Megha The QVGA-L and QVGA-P modes are not supported in the m5 SDK. Your application may still use them, but may face some issues with layout. It is recommended to use HVGA-L and HVGA-P modes. I used it only for test. Do you know about another emulators with another screen size? You can set the layout_height programatically using the LayoutParams class.http://code.google.com/android/reference/android/widget/LinearLayout Thanks. I did it. If you want to do this programatically, try using the constructor: ProgressDialog pd = new ProgressDialog(this, android.R.styleable.Theme_progressBarStyleHorizontal); I couldn't do it. OK. Now I decided forget about ProgressBar. I used ProgressBar and ProgressDialog at the same time, when I used xml layouts, but now I decided use only ProgressDialog, if it is so difficult or unimpossible to create ProgressBar programmly.

[android-developers] Re: Good example for showing exchanging of data mostly arrays or non premitive data types,objects
It is because the process can be killed when your application goes to
the background, so the system needs to be able to hold on to any
objects in its own process, to be able to return them to you in the
event of you being killed and restarted.
Note that due to this behavior, the approach suggested by Amos is
problematic -- if you go into the background and your process gets
killed, when your activity is later restarted the ReferencePasser will
be empty and you will no longer be able to retrieve anything from it.

Based on hackbod comments, I am still not confused, why one has to do
so much for passing references, it is my intent is to pass them by
refence and the underllaying framework should manage this irrespective
of cross components, cross process etc.. I also hate impl. interfaces
such as Serialisable,parcelble etc..at least in this context as it is
one device and that to mobile device. I am sure having framework take

Access to a single instance of ReferencePasser is achived through this

_passer = new ReferencePasser();
return _passer;

Here's a sample for an activity that wants to send an object to
another activity:
public class SourceActivity extends Activity {
...
private void startTargetActivity(SomeObject
myObject) {
ReferencePasser passer =
GlobalStuff.getReferencePasser();
long objectKey = passer.put(myObject);
Intent intent = new Intent(this,
TargetActivity.class);
intent.putExtra(com.myapp.blabla,
objectKey);
startActivity(intent);
}
...
}
And here's how the called activity gets the object
[android-developers] Re: How to associate my App with a file extension in the Browser
All of Android's file mappings are based on MIME types. As long as your web server is returning the correct MIME type, you can implement an activity that says it knows how to VIEW that MIME type and it will be launched when the user clicks on such a file after downloading it. On Mar 26, 3:34 am, Amos [EMAIL PROTECTED] wrote: Hi, I would like to implement the following scenario: When a user browses a web page with Browser and clicks a link with a special file extension (which is unique to my application, such as www.mysite.com/somefile.xxx), that file will be downloaded and then my application launched to view the downloaded file. I'd like the browser to handle the file download if possible, and when it's done start one of my activities and provide the file to it.

[android-developers] Graphics performance
Hello, I'm trying to write some highly graphics-intensive code. It's basically rendering into a pixel array (int[]), which I want to slam onto the screen as quickly as possible. What I'm seeing is rather disappointing. What I'm doing is copying the pixel array into a Bitmap object using Bitmap.setPixels(), and then drawing the Bitmap using a custom View class; the data's actually being produced from another thread, so there's also a postInvalidate() in there. Full screen, with a dummy drawing routine that just fills the array with garbage, this is maxing out at 25fps while using 100% CPU time. Does anyone have any suggestions as to what I might be able to do to speed things up? For example, is it possible to bypass the compositing layer somehow, which has *got* to be hurting things? Is there any way of getting the Bitmap's internal pixel store, so I can draw into that and save a copy?

This question and request has been asked before, however, I have not seen any direct response todate. Q: With the platform being toughted as open, why then would you hide or otherwise make certain features which many (read as a good majority) of the developers seek or need. Certain basic phone features are very useful in such a wide variety of applications. Aside form perhaps some of the obvious commercial reasons, what are the plans to make incercepting incoing call information, outgoing call information and a number of other call features which other developers have inquired about available?

[android-developers] Problem with IDs in R.java
Hello, I work on a Android project, for which I provided several new view components. Some of those are however rather general, e.g. a slider. I would put these components gladly in a jar to make them available to others. However I have the problem that the components using pngs from the drawable directory and that those are referenced only via ID in the R.java. If I export the project as a jar and bind it into another android project, the components don't use the pngs in the jar but the pngs referenced via ID in the R.java of the destination project.

[android-developers] Re: Good example for showing exchanging of data mostly arrays or non premitive data types,objects
How would you want to make it more transparant? If you want to kill activities when they are in the background and restore them when the user wants to see it again you have to save the state of the objects. Saving the state of objects is only possible if you marshal the object. If you only have a pointer to an object 'owned' by another activity you can't save the object to disk. - If you save the reference the reference may be invalid by the time the activity returns. - If you save the object the other activity still needs to be able to access that object So there is really no other way then to duplicate the object (using parceble) when you want to use the same data in multiple activies, or you have to use a seperate shared data source such as a content provider, or you have to create some other strategy where you make sure the data stays consistent.

[android-developers] How to post a new key event?
I am developing an on-screen keyboard activity and need to post a key event to Android. I can't figure out how to do it. I've intercepted some key events to see what Android methods are on the stack, and it seems that I need to call getParent() from my view until I get to the view root (android.view.ViewRoot, which is not an accessible class in Android application code) and then call this method: public void dispatchKey(KeyEvent event) ... I tried calling that method on my view root object using java reflection and passed the key event object that I created. That call was successful but no new text shows up in my EditText control which is located within the keyboard activity. My first goal is for the EditText control that is located within the keyboard activity (which maintains focus even while the key image is pressed) to show the text that I have entered using the keyboard. My second goal is for an EditText control that is in the Activity behind my keyboard activity to show the text that I have entered using the keyboard. I appreciate any help anyone can provide!!

[android-developers] Re: Graphics performance
My main issues is that the line drawing is usually faster than images on real phones for up to 12 or so lines, but not the emulator. The drawing images and 3d is actually not that bad for fast phones of 2003, but it should be about 8 times faster. 25fps is actually really fast, but like you said it is just a single test image. As far as speeding things up the most important thing is to reuse the Bitmap object and not create one each frame. I assume you are already doing that given your getting 25fps. Not much other than that is going to dramatically increase performance. If you follow Google performance advice document you are doing just about everything you can do. Remember the first arcade games that sold millions of copies only got 5-7 fps.

[android-developers] Re: Intent Receiver for android.intent.action.INSERT
You could use a content observer, but this would require your app
always running to monitor for changes.
I'm not sure of a solution off-hand besides updating your list when
your application starts. We deliberately decided to not support
having apps launched to be notified when data in a content provider
changes, because that can quickly lead to bogging down the system as
it launches a bunch of apps each time a piece of data changes.

Q: With the platform being toughted as open, why then would you hide or otherwise make certain features which many (read as a good majority) of the developers seek or need. Certain basic phone features are very useful in such a wide variety of applications. Aside form perhaps some of the obvious commercial reasons, what are the plans to make incercepting incoingcallinformation, outgoingcall information and a number of othercallfeatures which other developers have inquired about available? I think there have been many formal and informal request along this line... so whats theanswer?

[android-developers] Re: How to associate my App with a file extension in the Browser
Hello, I'm the Google engineer who works on that area of Android. Indeed, the download system is still under development, and you can expect to see changes there at some point. The two key aspects that you need to know is that: -the MIME type is what matters. The URI extension is not relevant in this case. -in order for the files to be downloaded and for your app to be launched, your application needs to register as a viewer the MIME type of your files (Intent.VIEW_ACTION). There's a high probability that in the long run the files downloaded from the browser will be saved on the SD card (which the emulator can emulate). However, I am not sure what the exact behavior is in the currently available SDKs. (For what it's worth, at the implementation level, there's indeed going to be some code that involves some content providers and some permissions, but at your level you don't need to worry about that, that's only used by the browser to manage its downloads). JBQ On Wed, Mar 26, 2008 at 5:52 PM, hackbod [EMAIL PROTECTED] wrote: This stuff is still under development, but I believe right now it is downloaded into a content provider that anyone can access. In the future, this will be downloaded to a more sophisticated download manager, that maintains per-item permissions so only the application requesting a download can access the files it is downloading, and it can then allow other applications to access particular uris -- such as when the user clicks on one of the downloads, granting the launched activity permission to open that particular uri.

[android-developers] Re: Intent Receiver for android.intent.action.INSERT
Great that you liked the idea. In fact, this would be useful for more than one application, so one small background service could actually keep track of changes for several applications. In this general sense, it would eventually be interesting for our project as well (OpenIntents - http://code.google.com/p/openintents/ ). Some caveats: * Whenever your service crashes or is stopped by the system or whenever the phone is rebooted, you probably can not be sure that no fields have changed in the mean-time, so then a full scan is necessary anyway. * Is it possible to get a hash of the whole database file, like an md5? Would the system allow this? Then one would only have to rescan the database if the hash changed while the service was off.

[android-developers] Who is responsible for closing FilterableListAdapters on AutoCompleteTextView
Hey I have a form with an AutoCompleteTextView which is backed by a SimpleCursorAdapter. My problem is that it seems that nobody closes the Cursors returned by runQuery(). I dont think that I as a user of SimpleCursorAdapter am responsible for closing them as there does not seem to be an obvious place to do that. Also the decompliation report (ups, should I say that?) of CursorAdapter seems to indicate that these cursors are simply lost and never closed. The effect is that after using the query feature a couple of times and dismissing the Form (I guess this is then when the garbage collector starts cleaning up) I get an IllegalStateException warning me that the cursor has not been closed. The documentation of SimpleCursorAdapter.runQuery does not mention that the cursor must be remembered and closed. Also even if I tried that, I dont find an obvious place (event) at which point it would be safe to close the cursors (I would need to subclass SimpleCursorAdapter or provide a FilterQueryProvider which would then remember all Cursors that have been handed out and only then clean them up at an appropriate time. I honestly think this is a bug. Any suggestions? I am so close to submitting my dev challenge project.

[android-developers] Re: Intent Receiver for android.intent.action.INSERT
I totally agree.To detect even a single change, I will surely have to rescan everythingThats a lot of work of course Dexter. On Mar 27, 9:30 am, severian [EMAIL PROTECTED] wrote: The problem is that ContentObserver.onChange() doesn't tell you what changed. So how do you figure it out? Well, as far as I can tell you have to keep your own copy of everything you might care about in the database, and then when you get onChange() you read everything from the ContentProvider and then compare it to your local copy, looking for changes. That is, you have to rescan the database with every change, not just between instantiations. But if I'm wrong, please tell me! Since you (DB) are storing a local copy anyway, this might be feasible, but for most purposes this is just too onerous to be useful. I really hope they fix this API to indicate what has changed, because ContentObserver is a nice idea - it allows different frontend and backend applications to share a common data pool. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Share XML files
I want to share data between two android phones, preferably by sending XML files, and I'm hoping for some feedback on what is the best way to do this. The reason I want to use XML is to keep things loosely coupled - this data could then be shared with apps on other platforms etc. One method I'm considering is (assuming there will be a standard bluetooth application for sharing files) to dump data from the SQL backend of my application into an XML file, that can then be sent in the same manner as any other file over bluetooth to another phone. I see that android has methods to write to a file, but where will this file live and will I be able to access it from a bluetooth app to then send it? I look forward to hearing any thoughts on this --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

It's a very intentional design. In fact originally the API did tell you what changed, but in many cases it is difficult if not near impossible to provide that information. The API is primarily designed for user interface elements like list views, and it turns out that it is really at least as easy for them to re-query the cursor and synchronize its new contents with the list, than to try to keep track of each change that happens and apply that to its representation of what is in the cursor (and hope that actually stays consistent with what is in the content provider). At any rate, it is far far safer to re-synchronize with the current contents of the content provider, than to try to integrate step-wise updates and try to actually guarantee that your view of what is in the provider actually matches its real contents. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
