[android-developers] Re: Widget-specific Preferences

2011-05-27 Thread Jake Colman


Kostya/String,

Is nothing ever easy?  So close, yet so far...  :-)

Some of my preferences have dependent keys.  Since the keys are being
renamed to be widget-specific I, of course, have to rename the dependent
keys accordingly as well.

Pref2 is dependent on Pref1.  Pref1 comes through my overridden
onPrepareAddPreference and I call setKey to rename its key.  Pref2 comes
through onPrepareAddPreference and I reset its key as usual and I also
reset its dependent key to have the correct Pref1 key name.  This
triggers a java.lang.IllegalStateException stating that Dependency not
found for preference. 

Since Pref1 has already been reset I would expect that by the time Pref2
comes in Pref1 is already out there.  Also, I did not think that
ordering would matter anyway as long as all the keys make sense at the
of the inflation.

Any ideas?

Incidentally, I tried both onPrepareAddPreference and addPreference just
in case one worked differently than the other.  And, yes, I called up to
super at the end of my overridden method.

...Jake

ProblematicClass should not extend Activity.

On Fri, May 27, 2011 at 9:10 AM, Marco net...@lavabit.com wrote:
 Thanks for the very fast response.

 The  only reason  I can  think of  for getFilesDir()  to
 return null is if it's not a real live Activity instance
 (you created it via new MyActivity() instead of starting
 it with startActivity(), you call getFilesDir() sometime
 after the activity is destroyed, etc.).

 Where do I have to call startActivity()?

 It's not unlikely that I make something conceptually wrong
 in my application, since I'm new to android.

 This is what I did:

 /*/
 // MainActivity.java
 public class MainActivity extends Activity {

    public MainActivity() {
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        // getFilesDir() works here
        AnotherClass myA = new AnotherClassImpl();
        myA.start();
    }
 }

 // AnotherClassImpl.java
 public class AnotherClassImpl implements AnotherClass {
    public AnotherClassImpl () {
        ProblematicClass props = ProblematicClass.getProperties();
 }

 // ProblematicClass.java
 public class ProblematicClass extends Activity {
    private static ProblematicClass myProblematicClass = null;
    public static ProblematicClass getProperties(){
        if(myProblematicClass == null) {
            myProblematicClass = new ProblematicClass();
        }
        return myProblematicClass;
    }

    public MediaSenseProperties() {
        // getFilesDir() failes here
    }
 }

 I hope  this illustrates my  method. All this  should take
 place in the same activity.

Re: [android-developers] Simpler UI Development with Android-Query

2011-05-27 Thread Olivier Guilyardi

Hello Peter,

It's a nice idea and project. I haven't tried AQuery yet, but I have a little
remark.

In your examples there is:

aq.id(R.id.icon).image(R.drawable.icon).visible().clicked(this, someMethod);

I'm not a big fan of this clicked() function. The problem is that the java
compiler cannot check whether someMethod exists, and also it is not available to
Eclipse refactoring, when renaming a method, which is a pretty handy feature.

I think that a clicked(OnClickListener listener) method could be better.

Also, having different methods for each click event isn't so nice.

For instance, in my case, I have a file manager, with about 10 buttons (not all
visible at the same time), but I have only one method to handle all clicks:

@Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.button1:
...
case R.id.button10:
}
}

I'm using this in quite a few places and find it pretty efficient.

To register my class as listener for all these buttons I use a small loop.

But, with jQuery you have these selectors and such which allow you to register
as event listener for multiple elements at once. Maybe that you could consider
the idea, for example with a method which matches all instances of a certain
View class, within a given ViewGroup.

Just a couple of ideas :)

[android-developers] Adapting BluetoothChat Example for One Server and Multiple Clients

2011-05-27 Thread polyclefsoftware

I'm attempting to adapt the BluetoothChat example that comes with the SDK to
a single-server, multiple-client configuration. I'm having issues and hope
someone can help.

I've created two distinct apps, a server and a client, rather than have a
single app function as both server and client, as in the example. So the
upon starting the app, the server creates a bluetooth service, which creates
a new AcceptThread, which listens for incoming connections. I made a couple
of modifications to the example code so that the AcceptThread continues to
listen, even after the first connection is made (the example stops listening
after the one connection is made, because it only needs to establish
connections between two devices). I created an ArrayList to handle the
multiple connections. Each time a new connection is attempted from a remote
device, a new ConnectedThread is created and added to the list.

The first client connects just fine.

When the second client attempts to connect, the connection fails. The log
output is:

D/BluetoothEventLoop( 140): Device property changed: device address
property: Connected value: true
I/BluetoothService( 140): ACL connected, mAclLinkCount = 2
D/BluetoothEventLoop( 140): Device property changed: device address
property: Connected value: false
I/BluetoothService( 140): ACL disconnected, mAclLinkCount = 1

So it looks like the second connection attempt is successful, but then it is
immediately disconnected. This looks like it's happening at a low level,
outside anything the code is handling. This happens with a number of
different types of test devices, so I don't think it's due to a particular
firmware or hardware issue.

Can anyone help with this?

Also, can anyone point to an example of a server-multiple client connection
example using bluetooth with Android? I came across an Air Hockey example:

http://code.google.com/p/apps-for-android/source/browse/#svn%2Ftrunk%2FBTClickLinkCompete%2Fsrc%2Fnet%2Fclc%2Fbt

But this project is very glitchy on my test devices and the actual game
won't display properly. Does anyone know if there is an example of
BluetoothChat extended to handle multiple connections?

Re: [android-developers] Re: Widget-specific Preferences

Jake,

I just tried it with a simple test, and yes, I get the same exception.

The reason is that setDependency() tries to register the dependency right
away, and doesn't find the depndency because the process of loading
preferences from XML hasn't completed yet (which it does not check).
It *might* be possible to work around it with more overrides here and there,
but... instead...

I admit that the idea only seemed good, and then was crushed to pieces by
the reality of how things work.

My apologies for having wasted your time.

[android-developers] Re: Two-way listeners/observers

2011-05-27 Thread Oceanblue

@Kostya: Thanks for your answer. Based on your answer, Handler does
sound better that AsyncTask for this. I looked a little bit into
HandlerThread, probabaly have to try it out to understand it fully.

One question though, forgetting about the whole native thing for a
moment... even if there are two Java classes (one Activity  one
backend) with methods running in two threads. Can they BOTH implement
listeners, hold a reference to each other  call each other's
listening methods? That would make the design really tightly-coupled.
Is there a design pattern to use where they both can listen to each
other  call each other asynchronously - whenever needed to?

On May 26, 1:07 pm, Kostya Vasilyev kmans...@gmail.com wrote:
 I would start by wrapping some of the C++ code in Java with JNI (you

 AsyncTask isn't really appropriate, because it's a task, not a process,

 item of work.

 You can use Handler objects, they are not necessarily tied to the UI. You'd
 need two: one on the UI thread owned by the activity, one owned by the Java
 wrapper of the back-end thread, and associated with that thread.

 Take a look at HandlerThread, that's the basic idea for your backend, except
 you'd be calling a native method for processing messages.

  I have an interesting design challenge:

  I have a frontend(Activity) and a backend (written in native C/C++)
  code. The backend is a complex object which partially controls the
  flow of application  once started runs in it's own thread. So I have
  a distributed control scenario.

  The Activity needs to be able to send messages asynchronously to the
  backend which then takes certain actions. But the backend also needs
  to be able to send messages asynchronously to the Activity, to which
  it responds by chnaging UI, firing methods etc.

  Essentially what I need is a two-way listener.

  So backend sends a message to screen (take picture, prompt user, get
  location, take another picture nowm etc) and screen does what it needs
  to do. But in addition, the screen should also be able to call the
  backend-listener to send back messages (captured camera image, system
  generated - I got paused/destroyed message, etc) in the callbacks of
  these events. Main problem is that this is all asynchronous.

  Is this possible without tight-coupling? Is this even possible?

  I have thought of Asynctask/handlers (but that's a one way street for
  informing the UI thread), observer-pattern (both objects will be
  observer/observable?) but confused on where to begin. Any thoughts,
  links would be very helpful.

Kostya/String,

Is nothing ever easy?  So close, yet so far...  :-)

Some of my preferences have dependent keys.  Since the keys are being
renamed to be widget-specific I, of course, have to rename the dependent
keys accordingly as well.

Pref2 is dependent on Pref1.  Pref1 comes through my overridden
onPrepareAddPreference and I call setKey to rename its key.  Pref2 comes
through onPrepareAddPreference and I reset its key as usual and I also
reset its dependent key to have the correct Pref1 key name.  This
triggers a java.lang.IllegalStateException stating that Dependency not
found for preference.

Since Pref1 has already been reset I would expect that by the time Pref2
comes in Pref1 is already out there.  Also, I did not think that
ordering would matter anyway as long as all the keys make sense at the
of the inflation.

Any ideas?

Incidentally, I tried both onPrepareAddPreference and addPreference just
in case one worked differently than the other.  And, yes, I called up to
super at the end of my overridden method.

[android-developers] Re: Text scaling properly on two different mdpi devices (Evo, and Galaxy Tab 10.1)

2011-05-27 Thread Mike

Robert,  one thing I have done to mitigate this problem is have
special code in my onCreate that checks for table-like resolutions
(e.g., width or height  854) and then do perform a scaling function
on the text sizes of those TextViews that need it.  It works, but
makes assumptions I would not like to make about display resolution
and physical screen size.  This obviously is not ideal, and is a
hack.  That's why I was wondering if the folks at Google could suggest
a better way to do this.

Hi Dianne,

I understand density to be a function of native resolution versus
physical display size.  So, the new Galaxy Tab 10.1 which has a native
resolution of 800 x 1280 pixels and a physical display size of 10.1
diagonal ends up being a mdpi device.  When I populate a
DisplayMetrics for the Galaxy Tab 10.1,  it gives me a density of 1.0
and a density dpi of DENSITY_MEDIUM which confirms this.

I misspoke with regard to the Evo.  I apologize.  It is indeed an hdpi
device.

In any case, I believe I still need to address this issue since a
device such as the myTouch (320x480 native resolution) is an mdpi
device as well.  Even though the myTouch and Galaxy Tab 10.1 have
drastically different native resolutions as you point out.  I've been
having difficulty using device independent units for mytextsize to
make the font look appropriate on both devices since they map to the

-- this use case is not well thought out at all by Google,
particularly how pairing works.  I'm hoping for some guidance from
someone there on how to make that work well, but I'm not holding my

I'm going to post the code for connecting two peers via bt spp comm
using qr codes if I can get it to work well enough.  If it all comes
together it will be a nice stop-gap until nfc is everywhere, which

Re: [android-developers] Re: Two-way listeners/observers

Agreed.

If the service is local, you can just direct Java method calls to
communicate, either your own scheme, or these guys:

http://developer.android.com/reference/java/util/Observable.html

But a direct Java method call won't switch threads for you.

For posting an event to the UI thread, your options are limited, because the
UI thread's loop is already implemented inside the Android framework.
Handler is one of those options, and you might as well use it in the
opposite direction as well, going from the UI thread to the worker thread.

An nice property of Handler is that it works with Message objects, which can
contain useful payload, including a plain Java object (no need to
serlialize, etc., as long as you're within the same process).

Here is a HandlerThread snippet from my current project:

http://pastebin.com/kpSFH6Ke

Clients call submitWorkItem on the UI thread, which processes them one by
one in onWorkItem(), on the worker thread.

Re: [android-developers] Re: Widget-specific Preferences

True. The initial values are set by onSetInitialValue, which is called
during initialiation (the last phase, onAttachedToHierarchy).

Resetting the values after adding preferences to the activity should work,
although might require some knowledge in the activity about what the default
values are. Better than an exception, though :)

Kostya/String,

Is nothing ever easy? So close, yet so far... :-)

Some of my preferences have dependent keys. Since the keys are being
renamed to be widget-specific I, of course, have to rename the
dependent
keys accordingly as well.

Pref2 is dependent on Pref1. Pref1 comes through my overridden
onPrepareAddPreference and I call setKey to rename its key. Pref2
comes
through onPrepareAddPreference and I reset its key as usual and I
also
reset its dependent key to have the correct Pref1 key name. This
triggers a java.lang.IllegalStateException stating that Dependency
not
found for preference.

Since Pref1 has already been reset I would expect that by the time
Pref2
comes in Pref1 is already out there. Also, I did not think that
ordering would matter anyway as long as all the keys make sense at
the
of the inflation.

Any ideas?

Incidentally, I tried both onPrepareAddPreference and addPreference
just
in case one worked differently than the other. And, yes, I called up
to
super at the end of my overridden method.

...Jake

Second, I don't see a call to populate() in your code. If you're calling

Those are for window animations, which are applied to an entire window.

Re: [android-developers] Adapting BluetoothChat Example for One Server and Multiple Clients

It doesn't work well in general, this seems to be something buggy going on

previously on the list, search around, I'll post some links later. But in
general, there's not much I've seen that can be done for this scenario (I
got three to work, and then after a while the connection died, I ended up
implementing application layer handler. But it seems the socker won't always
inform you of disconnection.)

 That sounds rather user-hostile, considering that you have no way of

 application. If you want that degree of control over the flow, use
 WebView in your own app, please.

[android-developers] java.lang.ArrayStoreException on Honeycomb device (Acer Iconia A500)

2011-05-27 Thread Emanuel Moecklin

I get the following exception:

java.lang.ArrayStoreException: java.util.LinkedHashMap$LinkedEntry cannot be 
stored in an array of type java.util.HashMap$HashMapEntry[]
at java.util.LinkedHashMap.addNewEntry(LinkedHashMap.java:193)
at java.util.HashMap.put(HashMap.java:412)
at java.util.HashSet.add(HashSet.java:95)
at com.mycompany.myapp.MyClass.void init()(MyClass.java:135)

Here's the code:
private LinkedHashSetCell cells;
protected void init() {
cells = new LinkedHashSetCell();
for (int i = 0; i  20; i++) {
cells.add(getCell(i));// -- that's line 135
}
}

getCell() always returns a Cell object. I'm 100% positive about that because 
it returns just values from an array:
private final Cell[] cells = new Cell[20];
Even if the Cell objects were Null it would work because HashSet supports 
Null elements.
Even if it would contain duplicate entries it wouldn't throw 
an ArrayStoreException but one of the other possible exceptions (
IllegalArgumentException, ClassCastException, IllegalStateException).

I assume the exception occurs because of Honeycomb for the following 
reasons:

   - I really can't see a reason why it could/should crash at all
   - the piece of code has run thousands of times on at least 100 different 
   devices without ever failing
   - I got the exception on an Acer Iconia A500 running Android 3.0.1.
   The percentage of devices running Honeycomb that the app runs on is still 
   too small to even show in the app's statistics.
   If it were a problem in my code it would have shown on pre-Honeycomb 
   devices already. 

Any ideas?

 this way when the slider/progress bar is at 0 sleep is 0; thus there

 when the slider is at 100 then sleep is 40,000, thus there is a 40

 As you can see I have a concept but I am not sure of the routines, I

[android-developers] ActionBar tabs - dynamic setIcon()

2011-05-27 Thread Vertifi Software

I'd like to use an ActionBar tab that has a text title of Messages,
and use setIcon() with a custom drawable to show an unread messages
count ... a little red bubble with a number inside.  This will attact
a users attention to the tab, letting them know there are messages to
be read.

No problem creating the custom drawable and setting it as the tab bar
icon, have that working fine.

However, when the # of unread messages is zero, I want this icon to
disappear.  I found that simply getting the tab from actionBar() and
calling setIcon(null) doesn't actually do anything on the tab.  I can
fiddle with visibility, but the icon appears to still occupy space in
the view, i.e. the text isn't centered.

Is going down the path of setCustomView() on the tab the only option?

Thanks in advance!

2011-05-27 Thread DanH

Offhand it looks like some sort of system bug, but hard to tell where
-- Map source code, interface method resolution, heap management --
could be anywhere.

(But one thing to beware of is multithreading -- Only HashTable is
thread-safe, and HashMap/HashSet can be tied in a knot if modified
asynchronously.)

But so long as you're not multithreading I don't think it's your bug
(though certainly a bug on your part could be exercising an untested
path in the system).

Thanks for the links. Your code clarifies things a lot.

Thinking about Handler/HandlerThread made me wonder about something...
Activity class provides a method called runOnUIThread(), which seems
to me a very straight-forward way to execute commands emanating from
other threads, on UI thread. Is there any idisadvantage of using this
instead of Handler or HandlerThread?

On May 27, 11:26 am, Kostya Vasilyev kmans...@gmail.com wrote:
 Agreed.

 If the service is local, you can just direct Java method calls to
 communicate, either your own scheme, or these guys:

 http://developer.android.com/reference/java/util/Observable.html

 But a direct Java method call won't switch threads for you.

 For posting an event to the UI thread, your options are limited, because the
 UI thread's loop is already implemented inside the Android framework.
 Handler is one of those options, and you might as well use it in the
 opposite direction as well, going from the UI thread to the worker thread.

 An nice property of Handler is that it works with Message objects, which can
 contain useful payload, including a plain Java object (no need to
 serlialize, etc., as long as you're within the same process).

 Here is a HandlerThread snippet from my current project:

 Clients call submitWorkItem on the UI thread, which processes them one by
 one in onWorkItem(), on the worker thread.

Re: [android-developers] Re: java.lang.ArrayStoreException on Honeycomb device (Acer Iconia A500)

This doesn't have to do with the types or null-ness of objects going into
the map, but rather with the implementaiton internals of LinkedHashSet.

LinkedHashMap . addNewEntry, line 193:

http://www.google.com/codesearch/p?hl=ru#cZwlSNS7aEw/libcore/luni/src/main/java/java/util/LinkedHashMap.javaq=LinkedEntry%20lang:javal=193

LinkedEntry extends HashMapEntry:

http://www.google.com/codesearch/p?hl=ru#cZwlSNS7aEw/libcore/luni/src/main/java/java/util/LinkedHashMap.javaq=LinkedEntry%20lang:javal=148

Definition of table, whose element is assigned to:

http://www.google.com/codesearch/p?hl=ru#cZwlSNS7aEw/libcore/luni/src/main/java/java/util/HashMap.javaq=LinkedEntry%20lang:javad=7l=94

an array of HashMap$HashMapEntry

Based on the above, the assignment at line 193 should succeed. Might this be
a Java runtime bug?

 of course if that's actually the version of java.util.* that is used in
Android 3.0.1.

But it looks reasonable, given that 1) the line number matches and 2) the

 Thanks for the links. Your code clarifies things a lot.

 Thinking about Handler/HandlerThread made me wonder about something...
 Activity class provides a method called runOnUIThread(), which seems
 to me a very straight-forward way to execute commands emanating from
 other threads, on UI thread. Is there any idisadvantage of using this
 instead of Handler or HandlerThread?

[android-developers] Re: Bluetooth is driving me nuts -- Galaxy tab lockups and pairing stupidity

2011-05-27 Thread Indicator Veritatis

In my experience, Bluetooth is often a little flaky, requiring pairing
when already paired, timing out before the user has the chance to
enter the code, etc. But I haven't seen anything quite as bad as what
you describe for the Galaxy Tab, and the flakiness I have seen never
seemed specific to Android.

On May 26, 6:58 pm, keyeslabs keyes...@gmail.com wrote:
 I'm trying to use bluetooth SPP to establish a socket connection
 between two Android devices.  There are a few things that are really
 driving me crazy in this effort.

 First, the Galaxy Tab seems to just be broken when it comes to SPP.  I
 can establish the connection just fine, but after a few minutes, and
 most notably whenever the app on the Tab on which the SPP server
 socket was established is killed, the tablet effectively locks up,
 requiring a hard reboot (hold down the power for 7 seconds to
 reboot).  I've seen others mentioning the same thing in various
 places, but haven't seen any solutions.  Has anyone come up with
 ANYTHING to solve this issue?

 Second, I've been struggling to find a way to make it easy for users
 to pair devices.  I'm developing a full-screen game involving two
 devices, and the pairing request on 2.3 and later seems to happen
 (sometimes) as a notification, which doesn't do much good for a full
 screen game.  In some cases it does seem to be displayed as a dialog
 (which is what I want), but it's frequently as a notification.  Is
 anyone aware of a reliable way to initiate pairing via DIALOG
 automatically when a socket is opened between two unpaired devices?

 Finally, has anyone else noticed pairing requests happening twice?
 Dialog shows, user clicks pair, second dialog appears, click pair,
 pairing happens.

 Thanks for any help!

 Core engineers on Android come from Sun, Be, Danger, Palm, Microsoft, as

 Also Blue Screen of Death is when your entire computer crashes.  Force

 Of course we could do like iOS and just silently kill the app and return to

Re: [android-developers] sensorLandscape orientation and disabled auto-rotate screen preference (Honeycomb)

No the point of this config is to allow it to rotate with the sensor.  The
user can still lock the screen to one orientation.

 Hi,

 My Honeycomb app uses the sensorLandscape orientation. On my tablet,
 when I uncheck the auto-rotate screen preference in the system
 settings, my app continues using the sensor to detect which
 orientation to use, instead of locking the 0° landscape orientation
 (as some other apps do, like Youtube, Pulse, CNN, but not Market).

 So, is there a way for my app to not use the sensor when auto-rotate
 screen is disabled?

[android-developers] SurfaceView vs View (Canvas Size?)

2011-05-27 Thread Frank

Hi All,

I am writing an application that needs to put a View inside a
ScrollView. Since View is used to display some content that is very
long, I do View.setMeasuredDimension(width, large_height) in View's
onMeasure() callback  function. I noticed that no matter how high the
View is, its Canvas size I queried in View.onDraw() is the same with
that of the viewport. This is good since the memory consumption is
only dependent on the size of the viewport. But the downside is that I
have to redraw the entire Canvas manually every time onDraw() is
called.

Instead of View, I can use SurfaceView. However, the problem is that I
cannot do SurfaceView.setMeasuredDimension(width, large_height). I
found that the Canvas size of SurfaceView is the same with its virtual
size (not the same with the viewport as View). So the underlying
Bitmap takes lots of memory and my application won't even run (because
of out of memory).

Does any of you know any solution to this problem? Thank you very
much.

Thanks,
Frank

Re: [android-developers] SurfaceView vs View (Canvas Size?)

You shouldn't put a SurfaceView inside of a ScrollView or other such
container.  Since a surface view is actually creating a separate window that
is positioned along with your window and provides the surface, those kinds
of interactions just won't work.

The way a scroll view works is that it expects to have one child view, whose
height is potentially larger than the scroll view.  If it is larger, then
the scroll view will change offsets to scroll around in it.  The view being
larger in height doesn't use any more memory or such -- this is just a
virtual coordinate space, with appropriate offsets and clipping applied by
the scroll view when it is drawn.

Calling setMeasuredDimension() in onMeasure() should definitely make it be
the size you specify.  Make sure you are not calling the super class
implementation or doing your code after calling the super class, since there
is a default implementation in View to set the measurements.  Also make sure
you are using wrap_content for the view, not match_parent.

You could try looking in hierarchyviewer to see what is going on with the
view hierarchy.

 Hi All,

 I am writing an application that needs to put a View inside a
 ScrollView. Since View is used to display some content that is very
 long, I do View.setMeasuredDimension(width, large_height) in View's
 onMeasure() callback  function. I noticed that no matter how high the
 View is, its Canvas size I queried in View.onDraw() is the same with
 that of the viewport. This is good since the memory consumption is
 only dependent on the size of the viewport. But the downside is that I
 have to redraw the entire Canvas manually every time onDraw() is
 called.

 Instead of View, I can use SurfaceView. However, the problem is that I
 cannot do SurfaceView.setMeasuredDimension(width, large_height). I
 found that the Canvas size of SurfaceView is the same with its virtual
 size (not the same with the viewport as View). So the underlying
 Bitmap takes lots of memory and my application won't even run (because
 of out of memory).

 Does any of you know any solution to this problem? Thank you very
 much.

 Thanks,
 Frank

hey, we found an issue in the packaging that are delaying things.

However, here's a workaround, by downloading the previous
platform-tools, revision 03, which contains the compiler we used in
3.0

Links:
https://dl-ssl.google.com/android/repository/platform-tools_r04-windows.zip
https://dl-ssl.google.com/android/repository/platform-tools_r04-macosx.zip
https://dl-ssl.google.com/android/repository/platform-tools_r04-linux.zip

Download, unarchive and replace the existing folder at SDK/platform-tools

Sorry for the inconvenience.

 then a new thread should be created off of the parent process. Is this

A new thread is created that executes Thread.run().  If you do exactly
what you have typed above, you will create a new Thread whose run()
does nothing, and the thread will exit immediately.

You should either be subclassing Thread and overriding run(), or
creating a class that is an instance of Runnable and passing that to
the Thread constructor.

[android-developers] Problem while inserting webview inside the progress dialog for twitter

2011-05-27 Thread Abhishek Soni

Hello everyone,
I am trying to implement twitter sharing for my application. I have used the
progessdialog with webview inside it for the twitter login. I am using
browser type of application so that once i am successfully logged in,
Twitter will send me to the callback url which is of my webpage. But when i
logged in successfully it doesnt send me to my webpage neither does
anything.

I was wondering is there any problem while using webview with progressdialog
in android 3.0 ?? Because this sharing is working fine with android 2.2.

Thanks in advance, aby
