Re: [android-developers] Issues with httppost: Authentication challenge is empty
Well, your webservice docs should tell you how to authenticate. Once you are

I am doing update every second and I am able to play the sound using mPlay = MediaPlayer.create(context, R.raw.chime); mPlay.start(); But after about 30 seconds, the sound stops playing giving the log error as follows: E/AudioTrack( 2106): AudioFlinger could not create track, status: -12 E/AudioSink( 2106): Unable to create audio track E/VorbisPlayer( 2106): mAudioSink open failed Then again the same sound starts playing after a pause of about 20 seconds instead of getting played each second.It continues in this fashion of playing the sound file for some seconds, then to the pause state and then again playing from startThis problem doesnt come into picture when I'm trying to update the sound on hourly basis for my hourly chime because in that case only once every hour this sound is played, same is the case for updation every minuteThis problem arises only for updating the sound each second Wat is the reason behind this delay??Can anyone please help me regarding this?

[android-developers] Re: What are some good Automated Unit And System Test Tools for Android?
Robotium is a black box test kit though. So while I am sure it's useful, I find that things like selenium and UI blackbox testing becomes rather hard to maintain on a changing live product where the design of the UI is under constant iterations. I think I have something that seems to be meeting my needs. I have Hudson setup to build my test Project whenever any changes happen in my repo. It calls the coverage target on a modified ant build script that I made from basically looking at how the sdk constructed it's build.xml template. It's semi documented how to do this, but basically you end up copy and pasting the entire contents of the appropriate template into your build file and setting the flag import=false on the setup tag included by default. Then since you can make custom changes at this point, I swapped out adb in the build script to use a custom adb wrapper wherever adb is called. This wrapper simply execs adb and interprets the success or failure of the command by reading stdout and returns a non 0 resultcode if it detects an error in the output. Then I found this, https://github.com/jsankey/android-junit-report, which you can use instead of the standard test runner and it will generate ant junit xml reports on the device for you (Really freakin convenient). I stash the resultcode of the test run, download the reports (emma, and junit xml) and then interpret the resultcode. Hudson later treats the emma report as a build artifact and publishes the reports in a nice fashion integrated with the SCM. It seems to be a pretty simple setup for running suites of unit tests through a device. Much thanks to jsankey again for that tiny but awfully useful bridge. I think I might extend this to include parsing out the performance stuff (ddmlib seems to have some stuff for this as well) and submit that back. -Greg On Nov 3, 1:33 pm, MarcoAndroid marco...@gmail.com wrote: This tool could be useful (integrates with Maven so should integrate with Hudson):http://code.google.com/p/robotium/ I still have it on my list as to look into :) On 3 nov, 07:20, Greg Giacovelli miyamo...@gmail.com wrote: So I give in. I approached this problem as an oh hey that's not too bad, I can write a bunch of unit tests, and I have been keeping my suite green. However as things get more involved continuous integration and testing is a great great thing to have.

So I setup Hudson and have it call the coverage target of the ant build.xml that the android executable in the sdk can generate. And then it hits me. adb -s emulator shell am instrument -w ... will never return a result code that is not 0 ... because adb technically exited cleanly and usually will regardless of how the shell command that executed did. So again I say, Oh that's not too bad, I can just wrap adb with a parser that parses output for errors and return a non 0 resultcode to fail my build if a test fails. Problem is then I also want to see what tests fail. I know eclipse is doing something smarter so I dig deeper and find the extra switches you can pass am instrument including the - r flag. adb -s emulator shell am instrument -r -w ... Now this is starting to get complicated as the output gets more complex and this originally thought simple task is getting more intense. As this SDK is maturing more I have to think, someone has endured this pain and made a kickass way to automate and report on these sdk tools and output. Like something complete with performance test tracking, code coverage reporting etc. These outputs all exit in the SDK but they just have to be adapted to the tools used outside. I have to think after a year or two this adapter(s) has to have been written. However I have only been able to find blackbox testing frameworks and not anything along the lines of regression test suite automation of the whitebox sort.

Re: [android-developers] ListView.setOnItemClickListener() fails to catch selection events for custom list items
Hi Bob,
since you are using ListActivity, you can override onListItemClick instead
of creating new OnItemClickListener. More information here
http://developer.android.com/reference/android/app/ListActivity.html#onListItemClick(android.widget.ListView,
android.view.View, int, long)
That should fix your problem.
Best regards,
Filip Havlicek
2010/11/4 FractalBob ruom...@gmail.com
I thought I knew how to catch list selection events in Android and
then I regained consciousness. In my situation, I have a ListView that
I populate with a custom view, all of the same class (let's call it
the NewsChannel() class). NewsChannel consists of a LinearLayout of
ImageViews and TextViews. When the list is displayed, the user may
select a NewsChannel item in the list; I want to find out which list
item was selected.
Also, I registered an onClickListener to one of the TextViews and that
works fine: when the text is clicked on, an activity is launched which
is looking for the position of the NewsChannel item in the list.
So, here's what my code looks like:
1. Registering the onClickListener in the ListActivity:
public class NewsListActivity extends ListActivity
{
.
.
.
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.news_list_format);
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView? parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
item_index = position;
Toast.makeText(getApplicationContext(), item clicked =
+ position, Toast.LENGTH_SHORT).show();
}
});
.
.
.
2. The layout for the ListView associated with NewsListActivity:
?xml version=1.0 encoding=UTF-8?
RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:orientation=vertical
android:layout_width=fill_parent
android:layout_height=fill_parent
android:background=@drawable/wpaper_tile
ListView android:id=@id/android:list
android:layout_width=fill_parent
android:layout_height=fill_parent
android:layout_alignParentTop=true
android:dividerHeight=15dp
android:divider=@android:color/transparent
android:cacheColorHint=@android:color/transparent
android:scrollbars=none
/
FrameLayout
android:layout_width=fill_parent
android:layout_height=55dp
android:layout_centerHorizontal=true
android:layout_alignParentBottom=true
android:background=#8800
/
ImageView
android:layout_width=fill_parent
android:layout_height=wrap_content
android:layout_centerHorizontal=true
android:layout_alignParentBottom=true
android:src=@drawable/phonetop_bg
/
/RelativeLayout
3. The NewsChannel layout:
?xml version=1.0 encoding=UTF-8?
RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=fill_parent
android:layout_height=wrap_content
include layout=@layout/news_heading_format
android:id=@+id/news_heading_header/
ImageView android:id=@+id/news_channel_image
android:layout_width=88dp
android:layout_height=66dp
android:layout_alignParentLeft=true
android:layout_below=@id/news_heading_header
android:padding=10dp /
TextView android:id=@+id/news_channel_text
android:lines=4
android:inputType=textMultiLine
android:layout_toRightOf=@id/news_channel_image
android:layout_below=@id/news_heading_header
android:layout_width=fill_parent
android:layout_height=wrap_content/
/RelativeLayout
When I run the app, the ItemClickListener is never called. However, if
NewsChannel were of a simpler type, say, a single ImageView or
TextView embedded in the layout, the callback does get called.
Any idea what I'm doing wrong? My whole goal is simply to let the
activity launched by NewsChannel (not shown) to find out which
instance of NewsChannel it was launched from. Thanks, in advance!

Pull down ListView (beyond top) to refresh. 2. Swipe finger across a ListView row to bring up actions/edit. First of all, iOS has some extremely well thought at and sensible UI/ UX patterns, many of them designed to get around the limitation of having one physical button (always needing a back button on screen, no menu key and so on). The danger here is that as Android developers we don't have this stuff built into the SDK, if you've tried to implement iOS's overshoot/ elastic ScrollViews which are purported to be coming to Gingerbread, you'll know how much extra work this can be, and potentially how brittle that might make code, especially if this particular feature is going to be built in. In response to the numbered points above, what about Android's click list view header to scroll to top, and what about the long-press for bringing up actions/options for an item. TweetDeck is one of the best examples of Android done right IMHO, fully embracing a lot of the design and interaction guidelines that are beginning to emerge. Are we going to confuse users by having an Android way to do things mixed in with an iOS way to do things? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: onConfigurationChanged not being invoked
How do you know that onConfigurationChanged is never called? Are you
overriding it and logging something there? Can you post the code of
that. Did you make sure you're using the correct method signature /
using @Override ?

kicks in, that onConfigurationChanged would get called but it does
not!
I do see in the log though this:

[android-developers] Adding table row by inflating does not take table's settings
Hi all. I have a table layout with a few predefined rows in it. Each row has only two columns. Now I need to dynamically add additional rows in it. I have two problems: 1) When programmatically inflating, I cannot set the index of the newly created row (I want it in place 'n') 2) After inflation, the inserted (actually appended) row doesn't listen to parent table's stretch column property. So here are my questions: q1) Can I set the place where to insert the inflated row programatically ? q2) Why doesn't the new row inflate properly (the second column is not shown because the first column doesn't contains a TextView with fill_parent. In the end I need the first column to occupy 80% of the screen width, and the second column remaining 20%. q3) is that doable with programmatic row insertions ?

[android-developers] Re: VerifyError: arbitrarily rejecting large method
Thanks a lot for the help and suggestions, which definitely guided me
to the solution of my VerifyError problem.
I just want to share the solution in case someone else encounters the
same problem, which appeared to be very simple - I only needed to move
the variables' definition outside of the method, i.e.,
**Original definition (when the VerifyError
occurred):**
public class PEModelOR extends BayesNet {
public PEModelOR() {
name = PEModelOR;
..
final DiscreteVariable DB =
new DiscreteVariable (DB,
DiscreteVariable.CHANCE,
new String[] { yes,no });
..
/some functions calling the above variables/
}
}
*Solution:**
public class PEModelOR extends BayesNet {
..
final DiscreteVariable DB =
new DiscreteVariable (DB,
DiscreteVariable.CHANCE,
new String[] { yes,no });
..
public PEModelOR() {
name = PEModelOR;
/some functions calling the above variables/
}
}
In such a way, I was even able to extend my model, which now includes
112 variables and 112 functions, all defined before the method
PEModelOR().

If it isn't, it is set in the SharedPreferences and if it was previously set output it into the EditText box. So, I enter a nickname and hit return but the text reverts to INPUT NICKNAME which was the temporaying in EditText label. Also, when I press menu and settings again, my previous entry is not in the EditText box as I expect it to be.

[android-developers] Re: One process, two live Application objects?
Dianne, have you stepped back from this position? I hope so. While I understand and agree that #onTerminate is not an option, Application#onCreate is very useful. I typically use it to kick off async events that I want to to occur each time the app is started. By tying it to Application#onCreate instead of to an Activity, I'm not twisted into knots by the Activity lifecycle. An example is to fetch the latest updates for the app from some web site. Its not critical when or even how opften it occurs, it just needs to occur and App#onCreate is the logical place. On a side note the standard Java implemetation of the singleton pattern (ie as a stateful static) has been on the outer for most of the last decade. IMO it was one of the reasons that made Spring dependency injection so attractive (along with clear config). Objects need lifecycle, the clearer and more dependable the better.

This gives you *nothing* you can't do in other, better ways.

[android-developers] Fwd: Not getting expected socket errors
We are still experiencing this issue in Ver 2.2. Is any one from the
Android Team comments on this issue?
-- Forwarded message --

Subject: Not getting expected socket errors
To: Android Developers
I think I have a closely related problem.
I launch one emulator running a server program (with appropriate port
redirections) and one emulator running a client. The client is able to
successfully make connections to the server.
Then I end the server program on the emulator, but do not kill the
emulator.
The client continues making active connections to the server emulator
without the server program running!!!
When I end the server program, I have made sure to close the server
sockets and even verified that the server thread on the server
emulator was killed using .isAlive()=false. I have also tried
programming this without using any threads, but rather executing the
server directly from the main activity (.onCreate()), and then finally
closing the sockets and calling this.finish() to kill the server
activity totally - again with no change in the problem. The client
continues to make connections to the emulator...
If I launch the client emulator alone, it does not make any
connections. If I launch the client emulator in conjunction with a
second emulator which has had appropriate port redirection (i.e.
telnet localhost 5554; redir add tcp:5000:7000) but has not
executed the server android program, I do not get spurious
connections. The problem occurs only when the server android program
has been run once. Once the program has been run, it seems to stay
resident on the emulator until the emulator is killed.
Any insight into this bizarre behavior would be appreciated.

Normally in TCP socket programming, if the remote end closes the

Here's some sample Android code to demonstrate. If you run

It will receive the test transmissions, but if you kill netcat, the
Android app keeps running without printing a stack trace, indicating
no exception has been thrown.
Socket socket = null;

socket = new Socket(10.0.2.2, 1234);

while (true) {
try {
Log.i(test, test);
os.write(test\n.getBytes());
os.flush();
} catch (IOException e) {

And a standard Java app. If you kill netcat while this is running,
you'll receive the expected SocketException.

private static Socket mSocket;
private static OutputStream mOS;
public static void main(String[] args) throws IOException {
try {
mSocket = new Socket(127.0.0.1, 1234);
mOS = mSocket.getOutputStream();

I was having a good deal of problems with the location listener starting / not starting / restarting when I didn't want it too (especially on Captivate phones) and it was further exacerbated by having multiple activities in my application.

[android-developers] Re: VerifyError: arbitrarily rejecting large method
Yep, the Dalvik compiler attempts to assign a register to every
local variable in the method. It should be able to handle that many,
but apparently can't. By making them instance variables you remove
the compiler's need/desire to manage them (and also make the method
a fair amount smaller).

Thanks a lot for the help and suggestions, which definitely guided me
to the solution of my VerifyError problem.
I just want to share the solution in case someone else encounters the
same problem, which appeared to be very simple - I only needed to move
the variables' definition outside of the method, i.e.,
**Original definition (when the VerifyError
occurred):**
public class PEModelOR extends BayesNet {
public PEModelOR() {
name = PEModelOR;
..
final DiscreteVariable DB =
new DiscreteVariable (DB,
DiscreteVariable.CHANCE,
new String[] { yes,no });
..
/some functions calling the above variables/
}
}
*Solution:**
public class PEModelOR extends BayesNet {
..
final DiscreteVariable DB =
new DiscreteVariable (DB,
DiscreteVariable.CHANCE,
new String[] { yes,no });
..
public PEModelOR() {
name = PEModelOR;
/some functions calling the above variables/
}
}
In such a way, I was even able to extend my model, which now includes
112 variables and 112 functions, all defined before the method
PEModelOR().

The method has 17,618 instructions, and requires 134 registers. Both
of these are on the large side. If you can find a way to break the

[android-developers] Re: ListView.setOnItemClickListener() fails to catch selection events for custom list items
Thanks for your suggestion, Filip. I added the following to the
ListView:
public void onListItemClick (ListView l, View v, int position,
long id)
{
item_index = position;
Toast.makeText(this, item clicked = + position,
Toast.LENGTH_LONG).show();
}
But it didn't get executed when I selected an item in the list (the
Toast never got displayed).
On Nov 4, 1:03 am, Filip Havlicek havlicek.fi...@gmail.com wrote:
Hi Bob,
since you are using ListActivity, you can override onListItemClick instead

That should fix your problem.
Best regards,
Filip Havlicek
2010/11/4 FractalBob ruom...@gmail.com
I thought I knew how to catch list selection events in Android and
then I regained consciousness. In my situation, I have a ListView that
I populate with a custom view, all of the same class (let's call it
the NewsChannel() class). NewsChannel consists of a LinearLayout of
ImageViews and TextViews. When the list is displayed, the user may
select a NewsChannel item in the list; I want to find out which list
item was selected.
Also, I registered an onClickListener to one of the TextViews and that
works fine: when the text is clicked on, an activity is launched which
is looking for the position of the NewsChannel item in the list.
So, here's what my code looks like:
1. Registering the onClickListener in the ListActivity:
public class NewsListActivity extends ListActivity
{
.
.
.
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.news_list_format);
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView? parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
item_index = position;
Toast.makeText(getApplicationContext(), item clicked =
+ position, Toast.LENGTH_SHORT).show();
}
});
.
.
.
2. The layout for the ListView associated with NewsListActivity:
?xml version=1.0 encoding=UTF-8?
RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:orientation=vertical
android:layout_width=fill_parent
android:layout_height=fill_parent
android:background=@drawable/wpaper_tile
ListView android:id=@id/android:list
android:layout_width=fill_parent
android:layout_height=fill_parent
android:layout_alignParentTop=true
android:dividerHeight=15dp
android:divider=@android:color/transparent
android:cacheColorHint=@android:color/transparent
android:scrollbars=none
/
FrameLayout
android:layout_width=fill_parent
android:layout_height=55dp
android:layout_centerHorizontal=true
android:layout_alignParentBottom=true
android:background=#8800
/
ImageView
android:layout_width=fill_parent
android:layout_height=wrap_content
android:layout_centerHorizontal=true
android:layout_alignParentBottom=true
android:src=@drawable/phonetop_bg
/
/RelativeLayout
3. The NewsChannel layout:
?xml version=1.0 encoding=UTF-8?
RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=fill_parent
android:layout_height=wrap_content
include layout=@layout/news_heading_format
android:id=@+id/news_heading_header/
ImageView android:id=@+id/news_channel_image
android:layout_width=88dp
android:layout_height=66dp
android:layout_alignParentLeft=true
android:layout_below=@id/news_heading_header
android:padding=10dp /
TextView android:id=@+id/news_channel_text
android:lines=4
android:inputType=textMultiLine
android:layout_toRightOf=@id/news_channel_image
android:layout_below=@id/news_heading_header
android:layout_width=fill_parent
android:layout_height=wrap_content/
/RelativeLayout
When I run the app, the ItemClickListener is never called. However, if
NewsChannel were of a simpler type, say, a single ImageView or
TextView embedded in the layout, the callback does get called.
Any idea what I'm doing wrong? My whole goal is simply to let the
activity launched by NewsChannel (not shown) to find out which
instance of NewsChannel it was launched from. Thanks, in advance!

Re: [android-developers] Re: color banding. can't get over it :(
Hatch,
I investigated this issue myself yesterday! My solution was pretty ugly,
I'll have to admit, but what I figured was that there's a color depth issue
when an ImageView is rendered over top something else. I ended up changing
my code so that the ImageView's parent would actually load the bitmap in and
draw it manually (in onDraw). So I had my ImageView in a RelativeLayout, so
I created a new class like this:
class MyRelativeLayout extends RelativeLayout {
...
public void onDraw(Canvas c) {
if(img == null) {
// lazily load the image
this.img =
(BitmapDrawable)getContext().getResources().getDrawable(R.drawable.image);
this.p = new Paint();
}
c.drawImage(this.img.getImage(),0,0,p);
}
}
In my layout xml file, I had basically this:
MyRelativeLayout android:width=yourImageWidth
android:height=yourImageHeight android:background=# /
For my purposes I had to keep it as a RelativeLayout because I added other
children to it.. but if you really only need a single image, it doesn't need
to be a RelativeLayout object.
Anyway, I'm guessing there's a better work-around for decent alpha blending
between Views.

[android-developers] Re: How different do the broadcast Intents need to be?
Dianne, Let me back up and give more context. My Activity draws various TextViews and other UI elements with data from a local SQLite database. When it can't find the data it needs locally, it draws a placeholder icon and generates a request to a web service for the data. The interface to the web service is enclosed in an IntentService which handles the background activity associated with the web service. When the data comes back, the IntentService places it in the SQLite database and generates a broadcast Intent back to the Activity, which has registered a receiver to receive the Intent. The Intent includes a tag so the Activity knows which UI element can now be drawn with local data. This tag is held in an Extra Bundle inside the Intent. This all works about 2/3 of the time. However, about 1/3 of the messages are being lost somehow. No exceptions are being thrown and there is no message in the logcat that seems associated with the receiver dropping messages. One added wrinkle is that my Activity encounters 10 UI elements where local data is missing and so it generates 10 calls to the IntentService in the space of a few milliseconds. 6 or 7 Intents are returned and 3 or 4 are missing. The exact number returned varies depending on the run. The entire process takes about 10 seconds. My understanding from Mark Murphy is that this is expected behavior, that Intents that look similar and arrive close by in time are considered duplicates and one of them is dropped. This behavior is not that hard to demonstrate in a test project so I could generate a case in b.android.com if you think what's happening is contrary to what should happen. It occurs to me that the Android regression tests may not cover the case of multiple calls to the IntentService spaced over a short period of time and sending back multiple Intents. If you think the behavior I'm seeing is incorrect then it sounds like there is a concurrency problem in the sendBroadcast method of the IntentService. Maybe sendBroadcast is not re-entrant? On Nov 3, 8:15 pm, Dianne Hackborn hack...@android.com wrote: I can't even follow what you are doing. First you were talking about broadcast receivers, now you are talking about Activity.createPendingResult.

Re: [android-developers] getting control value from within a dialog
Well, It's definitely an overkill. But, if you look at it's extensibility, it might suit you better. Say, for example, here the value of the control we have is a number. The layout might be a EditText, Slider or something else. If you do it thru the Custom Dialog, you can easily change the Dialog's appearance, or extend it later if you want, without changing your code all over. But, again, it depends on your requirement. If you are sure that you would not use this Dialog in more than one place, or you will not change the implementation later, TreKing's method is the best solution.

Tre, If our primordial ancestors had stuck to the accepted design patterns then we would still be living as slime on rocks. Variation is a good thing, even if it breaks with standards. That's how evolution works. If people create apps that are somehow more intuitive to use, they will attract customers and the standards will change because, at the end of the day, customers are the tail that wags this dog.

[android-developers] touch highlight behavior in a ListView
The default touch highlight behavior in a ListView is that the text starts as white on a black background and changes to white on an orange background when a finger is placed on the item. I'm using an ExpandableListView (ELV) which I've modified to include a 3rd level of list items. I see the expected touch highlight behavior at the top level of the ELV, just as with a normal ListView. However, I don't get any touch highlight behavior at the lower two levels. I presume this behavior is supposed to happen in the OnTouchListener for the selected View and that an ACTION_DOWN MotionEvent should trigger the color change and an ACTION_UP should change it back. It looks like I can call setBackgroundResource for the selected view to set the orange background. I have a few questions: First, am I on the right track - changing the background in the OnTouchListener? Second, is there a pre-defined resource that matches the standard orange color? If not, where can I find a Drawable that matches that color? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Missing ACTION_UP
I've got a view where I override onTouchEvent to detect touching the view with a finger and also to detect lifting the finger from the view. I'm getting the ACTION_DOWN event but not the ACTION_UP event. In fact, onTouchEvent isn't getting called when I life my finger. Could it be that the finger-down and then finger-up is considered a click event and so onTouchEvent is not called? If so, what use is ACTION_UP? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Missing ACTION_UP
So I set an onClickListener for the view and got the correct behavior. I do the highlight background in the onTouchEvent and then remove the background in the onClickListener. It's not pretty, but I don't see any other way, since ACTION_UP never seems to occur. However, this creates another problem. The view is swallowing the click and I want it passed up to the parent for other processing. Is there a method I can call in the onClickListener to cause the click to be passed up the view stack rather than consumed? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] sendBroadcast in IntentServicenot non-re-entrant?
I'm trying an experiment where an Activity makes a number of consecutive calls to an IntentService. Each call kicks off some background work that finishes in a few seconds. So there are multiple concurrent instances of the IntentService running. All the instances finish at around the same time and each one does a sendBroadcast to return a message to the Activity that it's finished. When this happens, about 30% of the broadcast intents never get back to the Activity's registered receiver. It looks as if there is some static state inside the IntentService class that is in conflict when there are multiple invocations running and they are all calling sendBroadcast at about the same time. In other words, sendBroadcast appears to be non-re-entrant. I'd like to package up this example for submission to b.android.com but before I do, I'd like to find out a few things from this forum: 1) Is this a known bug? 2) Is this expected behavior (ie not a bug)? 3) Has anyone seen anything like this or another case where the IntentService worked correctly when used in this way? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: ListView.setOnItemClickListener() fails to catch selection events for custom list items
I think the reason it's still not working is because I'm not sure what
interface onListItemClick implements, so I tried
public class NewsListActivity extends ListActivity implements
OnClickListener
and I implemented onClick, to no avail.
Anyone know what I should specify for implements?

I thought I knew how to catch list selection events in Android and
then I regained consciousness. In my situation, I have a ListView that
I populate with a custom view, all of the same class (let's call it
the NewsChannel() class). NewsChannel consists of a LinearLayout of
ImageViews and TextViews. When the list is displayed, the user may
select a NewsChannel item in the list; I want to find out which list
item was selected.
Also, I registered an onClickListener to one of the TextViews and that
works fine: when the text is clicked on, an activity is launched which
is looking for the position of the NewsChannel item in the list.
So, here's what my code looks like:
1. Registering the onClickListener in the ListActivity:
public class NewsListActivity extends ListActivity
{
.
.
.
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.news_list_format);
ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView? parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
item_index = position;
Toast.makeText(getApplicationContext(), item clicked =
+ position, Toast.LENGTH_SHORT).show();
}
});
.
.
.
2. The layout for the ListView associated with NewsListActivity:

True, except the inconsistency results in an incompleteness.

[android-developers] Re: Missing ACTION_UP
It occurs to me that this may be a consequence of the _kind_ of view I'm using. In this case, it's a TextView. I notice that the only onTouch event that the default TextView passes to my onTouch method is ACTION_DOWN. I'm guessing I need to set some flags elsewhere to get other events for this type of view. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Scanning through the TextView docs did not reveal any flags that I think would effect whether or not the ACTION_UP event was passed to onTouch. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Missing ACTION_UP
Now here's an AMAZING thing. When I change onTouch to return true (indicating that the event is handled) then the ACTION_UP event _is_ passed to onTouch. So returning false as a result of the ACTION_DOWN somehow tells the stack to pass the subsequent ACTION_UP to onTouch. This is not a fix, however, since I need to pass the event to the upper view layers for other processing. -- You received this message because you are subscribed to the Google Groups Android Developers group.

It looks like the only workaround is brute force. I can extend TextView to add a myParentView variable and then call the myParentView.onTouchEvent.

Re: [android-developers] sendBroadcast in IntentServicenot non-re-entrant?
Bret, You saying that there are multiple concurrent instances of the IntentService running is not entirely accurate. If you actually defined multiple services in Java / the manifest, my apologies. If you only defined one service, then there is only one instance of the service, and any intents it receives are queued up to a thread-safe queue as soon as they are received. The worker thread (there is only one, AFAIK) then de-queues intents from this queue and processes them one by one. So no synchronization issues there. However, it's not out of the question that calling sendBroadcast, with it being a framework function, is only allowed from the UI thread, just like many other framework functions in Android. Since you are able to consistently reproduce this problem in your application, I think it wouldn't hurt to run a simple experiment. Change calls to sendBroadcast so they are made from the UI thread (e.g. obtain a Handler in your service's onCreate, then post a runnable containing the intent to be broadcast to the Handler). Also: for the case you described, you could use a lighter-weight notification mechanism, such as ResultReceiver or Message. -- Kostya 04.11.2010 20:54, Bret Foreman пишет: I'm trying an experiment where an Activity makes a number of consecutive calls to an IntentService.
