My N1 has regular touch screen problems that are resolved by turning
the device off and on again.  There is a certain "state" that the
device gets into that regularly misinterprets presses as other
things.  I'll get random menus, vibration, and other strange behavior
until I perform to on/off sequence.

I got my N1 directly from Google last year from the developer support
program that rewarded either a ranking entry in ADC2 or a successful
Android Market app.  I can't tell which because I also got a Droid
from one of those programs.  But I do have regular touch screen
problems.  It seems to have a greater chance of flaring up after being
idle for a long time or after Maps navigation (it is a my primary
personal device these days).

While I'm griping about my N1, I'll point out that plugging it in
doesn't charge the battery until it gets lower than 90%, then will go
up to 100%.  That's just weird.

Doug

[android-developers] Re: Rotating a fragment

[Zsolt Vasvari]

Why would you need to handle the rotation changed event in the first
place?  I have a complex state data as well in some of my activities,
but I have no problems saving it using the normal callbacks.

[android-developers] VPN: L2TP: always timeout when Sending SCCRQ

[Jiejing.Zhang]

Hi All,

Hi Chia-CHi Yeh, I cc you since I found your kernel commit which is enable
VPN stuff.

I'm doing enable VPN function in an android froyo/gingerbread porting.
After apply android pppol2tp, pppopptp related patch in android/common.git,
I can success enable PPTP protocol, but I meet problem with L2TP profile.

My error is:
mtpd is keeping print error like this, then the connection will timeout

D/mtpd( 3020): Timeout -> Sending SCCRQ
D/mtpd( 3020): Timeout -> Sending SCCRQ

but SCCRQ in PPTP profile in return quite fast,
(I tested in Samsung 's Galax tab with same account and website, it works
with L2TP profile)

So, I'm suspecting maybe I missed some patch in kernel or some patch needed,
can anyone give some suggestion ?

Below is full vpn enable log:

[android-developers] Security exception with launchMode="singleTask"

[Akshay Goel]

Hello,

I have declared the launch mode of my activity to be singleTask. If I
launch my application, press the home button, go to an email client
(gmail in this case) & preview an attachment using my application, I
am experiencing a security exception on Android versions 2.3 & later,
which says that I do not have the permissions to access gmail
attachments. The exception does not occur on prior versions & if I do
not use singleTask as the launchMode.

Is this a known issue?

Any help will be really appreciated.

Thanks,
Akshay

To add, the exception occurs on this line-

mContext.getContentResolver().openInputStream(intent.getData());

where mContext is the activity context.

Hi All,

After apply this patch https://lkml.org/lkml/2011/1/2/82

pure l2tp VPN is working.

But I found L2TP+IPSec PSK, and L2TP+IPSec CRT profile is not working.

I can't capture any package in tcpdump, I suspect some crypto related
config.
could you give me some suggestions ?

Thanks.

[android-developers] VP8 player by RTP on Android

[Yoan]

Hello evebody.
First of all, excuse me for my English, but I'm not English-speaker.

I'm working on a project, and I need to find or develop a VP8 player
by RTP running on Android. That's means an Android application abble
to read VP8 videos by network (RTP protocol).

I found ffplay that can open VP8 videos, and can use RTP protocol. But
now, I have to adapt ffplay (in C language) for Android. Do someone
could help me to do that ? Maybe I have to use NDK ...

Thanks

[android-developers] Send an email in Android selecting only email apps AND specifying attachment mime type

[andrew]

In my Android App I send email messages with images attached.

Using the Intent system to send it, I can do one of the following two
things:

1) Specify type as "message/rfc822" so that ONLY email applications
are shown in the Chooser.

Inconvenience: I cannot specify the mime type of the image I attach
using EXTRA_STREAM and a Uri. Many receiving email apps (Gmail,
Android, etc) show this as an unknown binary "blob" attached to the
message, don't know how to preview it and don't know how to open it as
an attachment.

2) Specify the type as (say) "image/png". The image is attached and
email clients such as Gmail can preview it, and open the attachment in
the appropriate application.

Inconvenience: For the sending user, I cannot reduce the list of apps
the user has to select from in the Chooser to email apps, and MANY
apps are shown in my Android device, most of which are not email apps
and not what I want.

Is there anyway to specify its a "message/rfc822" email Intent AND to
specify the MIME type of the data attached via Uri in the
Intent.EXTRA_STREAM?

BTW: I am providing the file from my own ContentProvider and the
getType() method (used to determine file MIME type) is NOT being
called. The query() method is but doesn't request the file type, only
display name and file size.

thanks

You will find approximately zero books on writing Android apps in PHP.
I say "approximately" because it might get brief mention somewhere
that discusses SL4A. PHP on Android is a niche of a niche.

In terms of Android development in general, here's the top
StackOverflow question on the topic:

http://stackoverflow.com/questions/1114287/good-book-for-beginning-android-development

In the interests of full disclosure, I'm mentioned in the answers.

Re: [android-developers] Send an email in Android selecting only email apps AND specifying attachment mime type

[Mark Murphy]

If you are willing to roll your own dialog, you could:

Step #1: Create the message/rfc822 Intent, as if you were going to
send that way, and use it with PackageManager and
queryIntentActivities() to find out who handles it.

Step #2: Create the image/png Intent, as if you were going to send
that way, and use it with PackageManager and queryIntentActivities()
to find out who handles it.

Step #3: Compute the intersection of those two sets of activities.

Step #4: Use those to populate an AlertDialog for the user to choose from.

Step #4a: If the intersection has one match, skip this step.

Step #4b: If the intersection has zero matches, let the user know
you can't send the message.

Step #5: Modify the image/png Intent to add the component selected
from the dialog, and call startActivity() on it.

By specifying the component in the Intent, it will go to that
particular activity. This is effectively what the regular chooser
does.

Exporting APK does not change Manifest file.

To debug on the phone you simply set debuggable to true and upload?

[android-developers] How to exclude test resources from generated APK?

[Greg Brown]

Hi all,

I'm using Eclipse to develop an Android application. I have a number
of resource files in my project that are used for unit testing. When I
generate an APK file for my app using "Android Tools > Export Unsigned
Application Package", the generated file includes these data files. I
have not been able to find a way to filter them out.

Is there a configuration file somewhere that I can modify to exclude
these files?

Thanks for your help,
Greg

Re: [android-developers] Re: Security exception with launchMode="singleTask"

[Dianne Hackborn]

Sorry, this is probably a bug in 2.3 with trying to grant a URI permission
to an activity instance that is already running.  I'll look in to this.  In
the mean-time, the only solution may be to not use singleTask for the
activity being launched to a preview an attachment.  This is actually the
preferred thing to do, since your preview activity should be running as its
own instance as part of the gmail task.

Re: [android-developers] Re: Flaky Touch Screen on Nexus One

[Dianne Hackborn]

Re battery levels -- the batteries on these devices don't simply charge to
100%, they will charge up 100%, then drain down some amount (toward 90%),
then charge up again.

The Droid's hardware only reports battery level in 10% increments, so you
wouldn't see the behavior there.  Also some manufacturers hide this charging
behavior when they report the battery level so it doesn't confuse users.

Re: [android-developers] Re: Query regarding getFlags() of Intent

[Manohar Mahapatra]

Hi Dianne,

Thanks for the reply. I want to let you know the exact dilemma I am in.

My application is a client based financial app and compulsorily it needs to
validate the user token from the server every time it comes to foreground.
This is a security mandate.

Are you aware of any call back( ( Activity) or (Context ) level)/or
any workaround  that we can use when the App is brought to foreground from
the Recent Apps. Usually the user of my app would be in some secondary
activity launched by the root activity.

I works fine in all the App launch scenarios except the Recent App workflow
where any of my Secondary activity has *no way* to know that it has been
brought to the foreground from the Recent Apps.

If you are aware of some good practice for this kind of situation,
any suggestion or advice would be greatly appreciated.

Thanks
AndUzer

Then validate the user token in every activity in onResume(). I fail

Android applications don't "come to foreground" any more than Web
applications do.

[android-developers] Change UI when executing an instruction

[Alaeddine Ghribi]

Hello,
I want to change the UI(if possible just add an image to the UI) when
i'm well connected to the server(i'm developping a SIP application) by
adding an imaged "Connected" .
In fact, i've made this but i have a FC:
public void onRegistrationDone(String localProfileUri, long
expiryTime) {
updateStatus("Registered to server.");
Log.d("SUCCEED","Registration DONE");
setContentView(R.layout.connected);
}

connected is an XMl file that has a textview(with same id as the
main.xml) and the image that i want to add.
How can i do this?

Thank you very much.

Do they actually need to be in your main .apk?  Generally we like to keep
all test related code (and resources) in a separate .apk that has the
Instrumentation components.

Re: [android-developers] Re: Query regarding getFlags() of Intent

[Manohar Mahapatra]

Hi Mark,

Thanks for the reply. You are right , I could have used onResume in
my secondary(not root activity) activities, but onResume will be called
 even when I navigate between the activities in my app once it is launched.
. I dont want to check the user token during this scenario as it would be a
overkill.

My requirement is if my application( hint app task level) as a whole is
brought to foreground ( see the two cases below)

a) From the Home page - works fine in this scenario
b) From the Recent Apps - has the issue , here i cant know the onResume for
any secondary activity  is called due to an internal navigation or due to
the *app task* coming to the foreground again. So i thought of using the
FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY
 from any of the secondary activity but I get 0 when I query for getFlags()
in any of the secondary activity

thanks
And Uzer

IMHO, your requirement is flawed. It's almost as flawed as those who
think they need to find out when their "application goes in the
background" to log people out.

Any sensible Web application would use a time-based mechanism based
upon session cookies. After N minutes (either since login or since
inactivity) -- or if there is no session cookie -- force a
re-authentication. IMHO, sensible Android applications will take the
same approach.

Unless you manage to trigger any sort of rarely exposed bug, it's mostly not
related to exporting your app. I assume you changed this that way or
another. If not, then describe step-by-step what you do to make this happen.
Please check if it really happens all the time.

Re: [android-developers] Change UI when executing an instruction

What about just having you all UI elements in one view but simply hide/show

Looks like you do not need anything more complicated anyway.

Re: [android-developers] Change UI when executing an instruction

[Dianne Hackborn]

setContentView() completely replaces your current UI with a new one.  If you
just want to make an image shown, you need to modify the current UI -- for
example have an ImageView containing the image which you change between
View.INVISIBLE and View.VISIBLE.

ImageView iconView = (ImageView)
findViewById(R.id.connected);
iconView.setVisibility(1);

}
But the image diesn't shows!
Here is also my XML file:
http://schemas.android.com/apk/res/
android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">

http://schemas.android.com/apk/res/android";
  android:id="@+id/sipLabel"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  />
  


What could be the problem?
Thank you very much.

First thing is to actually use one of the correct constants in

[android-developers] Re: testing NotificationManager and other system services

[Bob Kerns]

Better solution: All services should be defined via interface, with nary an 
implementation class to be seen. Specifying an implementation class, as the 
current spec does, does not add value -- it removes it.

Workaround: Define your own interface class, and your own method that calls 
getSystemService, and wraps the return value in an instance if your 
interface, which delegates to the system one. Then, to generate a mock one, 
generate a mock of your interface. Don't use the system's implementation 
class in your code, but rather your interface, and you're fine.

This is easy. What's hard is doing this N times for all the places this 
simple design rule is not followed in the system, where N is extremely 
large. But you can at least automate your wrapper object implementations 
using the java Proxy mechanism and reflection, for everything but 
performance-critical objects.

[android-developers] Handling ACTION_SCREEN in a widget

[Pedro Duque]

Hi,

I'm doing a widget that needs to be update on screen_on or on
user_present. As I'm not hable to register a BroadcastReceiver inside
the widget I'm doing it in a Service that is triggered by the widget
like this:

Widget.java:
    @Override
    public void onEnabled(Context context) {
        super.onEnabled(context);
    context.startService(new Intent(context,
WidgetService.class).setAction(WidgetService.ACTION_WIDGET_START));
    }

WidgetService.java:
    @Override
    public void onStart(Intent intent, int startId) {
    super.onStart(intent, startId);

        String action = intent.getAction();
        Log.d(LOG_APP,"WidgetService onStart: "+action);


        if (ACTION_WIDGET_STOP.equals(action)) {
    this.unregisterReceiver(mReceiver);
            stopSelf();
            return;
        } else if (ACTION_WIDGET_START.equals(action)) {
    // register receiver that handles screen on and screen off logic
    IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
    this.registerReceiver(mReceiver, filter);
    return;
        }

The problem is that when I try to register the receiver I get the
error that the service has leaked IntentReceiver because it was
already registered. Ive checked and no duplicate registration was done
in my code.

Do you have any idea what I'm overlooking?

Thanks,
PMD

[android-developers] Re: AdSense in Admob banner?

[groob]

Hello, Nikolay!

Thanks for your answer.

I think it is not the code I should blame here.
When I'm launching on my device Admob's examples (BannerEssentials,
Banner-Details) I get exactly the same result.
Also bannrers in other applications I downloaded from the market look
equal.
This makes me more think of my device and applications installed on it
being guilty of the problem.
Unfortunately I have no other Android phone available at the moment
and emulators are displaying correctly red Admob test banner.

It looks to me like AdSense's HTML code is, after being received,
somehow wrapped (interpretted?) by some app installed on my device and
thus not fitting the default 320x50px space.

Your advice on changing Admob console settings doesn't help either -
once AdSense disabled, no ads are received. I think Google want to
teach me a lesson that fill rate will decrease indeed without
AdSense. ;)

Best,
groob.

[android-developers] Re: System.exit

[Bob Kerns]

Perhaps you yourself are getting in the way when you offer offense in this 
way? I for one am glad that Dianne does not work at the sort of company you 
describe, and there's really no way to take your remarks addressing her job 
security but as a personal attack. I'm not sure why you're doing this; it 
seems out of character for you.

I am probably one of the few people on the list who'd find your SylloGizmo 
references interesting, and I did not find it relevant. Hence, in effect, 
commercial SPAM. (I know that was not your intent).

If you found Dianne's answer inadequate, just answer it yourself.

Like this:

No, it's not OK to call System.exit().

I further argue that any discussion of hypothetical exceptions are not what 
the OP needs. If you're asking the question, you don't have nearly enough 
understanding of the issues to even evaluate them. For example, whether 
System.exit() cleans up the activity stack (it doesn't, as has been pointed 
out) is not something someone who is asking this question understands at 
this point.

I am probably one of the few people on the list who'd find your SylloGizmo 
references interesting, and I did not find it relevant. Hence, in effect, 
commercial SPAM. (I know that was not your intent).

If you found Dianne's answer inadequate, just answer it yourself.

Like this:

No, it's not OK to call System.exit().

I further argue that any discussion of hypothetical exceptions are not what 
the OP needs. If you're asking the question, you don't have nearly enough 
understanding of the issues to even evaluate them. For example, whether 
System.exit() cleans up the activity stack (it doesn't, as has been pointed 
out) is not something someone who is asking this question understands at 
this point.

[android-developers] How does the ActivityStack behave when it contains thousands of Activities?

[Scythe]

In my app I have a about a dozen of different Activities. These
Activities are connected (can call each other with startActivity()) in
such a way, that the user can theoretically keep running in circles -
always jumping to the next Activity, never going back. Also, I really
need to maintain a proper Activity history: if the user presses the
back button, the app returns to the previous Activity, with the
previous content.

Question: Suppose the user's using the app for an extended amount of
time, going in circles between Activites as mentioned above, resulting
an ever-growing ActivityStack. Every Activity saves some state on
onSaveInstanceState() too.

- Is this a problem? (I'm afraid it is, I guess it's a memory leak to
have tens of thousands of Activity records on the stack, especially if
these save their state).
- Is there a way to limit the size of the default Android
ActivityStack's size? (size limit is X, we delete the oldest record if
it gets filled up)

Any suggestions / alternative solutions are welcome.

You will perhaps run into stack overflows or oom.  Android will try to kill
some of your activities though when it finds necessary

Yes.

The view that's above the ImageView is set to fill_parent height, so it 
takes the entire height of the screen, leaving no room for the image view.



Thank you.

[android-developers] Re: AdSense in Admob banner?

[groob]

I know where's the problem - my network operator in Poland (Era, from
T-Mobile) adds a service called 'Compressor mini' (which is in fact
Opera Mini feature), that is to limit data transfer.
Unfortunately it adds as well this toolbars.

Don't even ask - I'm pissed as hell on them, especially they disagree
to turn it off.

Re: [android-developers] Re: Change UI when executing an instruction

[Alaeddine Ghribi]

Excatly that's the problem, i didn't notice it, i just copied it from my
previous project :P !
However, i want to set the image to show after a period, i've maked this:

public void onRegistrationDone(String localProfileUri, long expiryTime) {
updateStatus("Registered to server.");
Log.d("SUCCEED","Registration DONE");
final ImageView iconView = (ImageView)
findViewById(R.id.connected);
iconView.setVisibility(1);
iconView.postDelayed(new Runnable() {
public void run() {
iconView.setVisibility(0);
}
}, 5000);

But it's always showen.
Any idea how to fix that problem ?

Thank you.

[Kostya Vasilyev]

As was already pointed out by Dianne, View.setVisibility() uses 
constants, like View.GONE and View.VISIBLE - not arbitrary values like 0 
or 1.

[android-developers] When exactly do you need to handle DeadObjectException with services?

[MarcoAndroid]

Hi there,

In the Additional Notes section here:
http://www.devdiv.com/android/docs/guide/topics/fundamentals/bound-services.html#Binding
it says: "You should always trap DeadObjectException exceptions, which
are thrown when the connection has broken. This is the only exception
thrown by remote methods."

1) Does that mean that for all calls of the client to the service's
methods you need to try/catch the DeadObjectException? Even
getService() in onServiceConnected() can throw it?

2) If my service only uses a local binder (LocalBinder in the example
from the above link), so it is private to my own application and runs
in the same process as the client, can I then still get
DeadObjectException? I wonder because I see with this type of binding
that the service does *not* appear in the services overview of a
device or emulator, which makes sense to me because it is "tightly"
connected to the activity that bound to it. That to me means you (nor
the Android runtime) can end the service on its own, so never a chance
on DeadObjectException... True?

Thanks!
Marco

Sorry but i'm not understanding your point. If i make iconView.VISIBLE i
have an error(sorry for my mis-understood).In the XML file i have to do like
android:visibility="visible" and in the JAVA code i normally make
iconView.setVisibility(1);

You need to catch them wherever they can be thrown.  You actually don't need
to worry about this, because this is a checked exception so if you forget to
check it somewhere you will get a compile time error.

No you can't get it, because it is in the same process, so if the service's
process goes away then your client code's process has gone away as well and
never could have gotten a result.

However because the interface generated by aidl can be used with a remote
object, at compile time there is no way to know whether or not this will be
the case, so the interface methods must declare they throw RemoteException
and you thus must handle if if calling those methods.

One way to get around this is when implementing those methods in the service
do not declare them as throwing RemoteException and on the client side cast
the interface to this implementation class.  Now the compiler knows that a
call to the method will never throw that exception.

Or just catch the exception and do nothing, or print a quick log, or
whatever.

[android-developers] Updated .apk wants uninstall first

[Derek Winstead]

I have been developing an app I want to share with friends and family for 
beta testing before I publish it to the android market. Problem is, since 
I've already had them install a previous version of the app, that when I 
send them the new .apk to install the installer wants the already installed 
app to be uninstalled first before the new version can be installed or 
updated.

Is this something I'm doing wrong in my program? I want the SQLite DB to 
always be intact and never loose data which is what happens when someone has 
to reinstall/update the app.

Please help! Thanks so much.

Derek

Re: [android-developers] How does the ActivityStack behave when it contains thousands of Activities?

[Dianne Hackborn]

It doesn't.  Don't do that.  Allowing the user to keep cycling through
activities is fundamentally flawed.  Having an application that has more
than a handful of activities on the stack is not correct, both for the way
the system works and the user experience it causes.

Re: [android-developers] Updated .apk wants uninstall first

[Dianne Hackborn]

I assume you have changed the cert.  If this is the cause, no there is
nothing you can do about it.  The cert is the identity of the author; two
apps with different certs are fundamentally different apps and can't be
installed on top of each other.

Re: [android-developers] Updated .apk wants uninstall first

[Derek Winstead]

Where do I change the cert? That doesn't sound like something I've done 
(knowingly).

When doing my development on the ADV with eclipse I make my changes and 
rerun the program. It reinstalls everything but I don't loose data. Only 
when I try to push it to a real phone does it want an uninstall.

[android-developers] Re: Updated .apk wants uninstall first

[JP]

The development and release .apk files are signed with different
certificates.
In other words, when you hand out an .apk that was created when you
ran an Eclipse build, you are distributing an .apk that's signed with
a cert different than the .apk which you generate for release (which
you run through zipalign and signing with the release key).

Ok, so when I right click my project and Run As -> Android Application it 
installs on the VM but also creates the .apk file in the bin folder and that 
is what I'm coping and sending to friends. Is this incorrect to do?

I'm still a novice with Android.

[#13point7]

It is fine to do that, but the Release version has a different signature. So 
if they have the Development apk installed, then they have no choice but to 
uninstall that to install the Market apk. This is only the case when going 
from Development -> Market...any subsequent updates will be fine and data 
will be retained.

I figure that multiple smaller images work better than the '1 large image'

[android-developers] Documentation for older Android SDK versions?

[Stefan at WPF]

Hello,
when browsing the Android SDK documentation, e.g.
http://developer.android.com/reference/android/preference/PreferenceActivity.html,
then this documentation is for the latest Android version (Android 3.0 r1 at
the time of writing this).

As I am developing for Android 2.2 it is very confusing for me to read the
Android 3.0 documentation, e.g. it claims for addPreferencesFromResource(int
preferencesResId):

This method is deprecated. This function is not relevant for a modern
fragment-based PreferenceActivity.

Well, for Android 3.0 it might be, but seen from Android 2.2 it is probably
not. So where can I find a documentation written from an Android 2.2
perspective / the documentation written at the time of Android 2.2? On e.g.
MSDN you can easily switch between the different documentation versions for
e.g. .NET 3.5 and .NET 4.0, how about the Android documentation?

Please note, that using the API Level Filter is not enough, even with API
Level 1 (the lowest API Level where nothing can be deprecated) it claims
that addPreferencesFromResource(int preferencesResId) is deprecated - the
filter acts in a too simple way, just filtering out APIs with newer API
Levels than the one specified for filtering.

Thank you very much :-)

[android-developers] Re: Documentation for older Android SDK versions?

[Nicholas Johnson]

AFAIK, you can't, unless you saved the Android 2.2 SDK when you downloaded 
it (you might also find someone on the net who has it). 

However, of all my apps that I have, 3 are developed for Android 1.6 and one 
is developed for Android 1.5. I don't have too much of a problem reading the 
SDK. I wouldn't let the "deprecated" get you down too much. Because, in 
fact, the method is deprecated but is still good and works fine.

[android-developers] Re: Fragments for Google Maps add on?

[Streets Of Boston]

The new contents of FragmentActivity.java are in my earlier post.
 
The AFragmentActivity.java is a copy of the original FragmentActivity.java 
with these additional changes:

   - public class AFragmentActivity extends Activity *implements 
   FragmentActivity* 
   - Then fix the compiler errors from the change above (i.e. implement 
   missing methods that are defined by the FragmentActivity). This is pretty 
   trivial.

The AFragmentMapActivity is a copy of the AFragmentActivity with these 
additional changes:

   - public abstract class AFragmentMapActivity extends *Map*Activity 
   implements FragmentActivity

Then you'll find that other source files in the compatibility have some 
compiler errors. These are trivial to fix. Mostly adding (Context) or 
(Activity) casts and calling '.getFragments()' instead of '.mFragments' and 
such.
 
Here is a usage example:
*public class Main extends AFragmentMapActivity {
 
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}*
* @Override
 protected boolean isRouteDisplayed() {
  return false;
 }
}*
 
*public class MapFragment extends Fragment {
 private ViewfragmentView;
 private MapView mapView;*
* 
 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container, 
Bundle savedInstanceState) {
fragmentView = inflater.inflate(R.layout.map, container, false);
mapView = (MapView)fragmentView.findViewById(R.id.mapview);

return fragmentView;
 }*
*}*

And the layout main.xml has a  in there that refers to *
MapFragment*.
* 

*

But that's exactly the situation I have.  My entire data set changes
from second to second.  My app displays a list of financial trading
markets in real time, showing bids and offers that change.  I never
know from one second to the next how many items the list will have,
because the market orders come (new order), go (traded or cancelled
order), and change (modified order price, etc).  The data set I'm
viewing is not a static size.  I don't think there's any other way for
me to display this data other than to tell the ListView its data set
has changed.  I would have to write my own 'list view' replacement if
I needed to optimize this.  However, contrary to what you may think,
the performance is more than acceptable.  This paradigm has been in
use on the iPhone for 2 years, and it performs extremely well.  The
Android 'port' of the app, thus far, performs almost as well as the
iPhone.

The reason I posted the original question was to ask why my touch
events would be 'swallowed' or 'lost'.  Do you see my relatively
frequent calls to ArrayAdapter.notifyDatasetChanged() causing the
Touch Events to get 'lost'?  If so, I would be highly confused if that
were the case.  All of my drawing, and all of the touch events, are
happening on a single main/UI thread, so I don't understand how, or
why, the Touch Events would get lost.   Even though the data is
streaming in on an background thread, i coalesce the changes in the
background thread until the UI can 'pop' the data off and redraw.
There is no thread starvation going on because the data thread
notifies the UI thread only one time, and then the UI thread schedules
a handoff to grab the data from the background thread when it is next
available.  And the update mechanism then continues from there for the
next cycle.  I would hope that the Touch Events would not get 'lost'
in all of this, but from my testing it appears some of them might be,
and I'd like to understand why.

[android-developers] Re: Flaky Touch Screen on Nexus One

[Eric]

By the way, this Google I/O video on ListView seems to indicate it is
perfectly acceptable, and in fact required, that you call
notifyDatasetChanged() when anything in your dataset changes (either
individual cell content, or data set size).  Nothing in this video
says you should be iterating through your list view cell Views
manually and updating them yourself (rather than call
notifyDatasetChanged()).  In fact, this video says never manually
access the Views in your ListView!

[android-developers] Re: Flaky Touch Screen on Nexus One

[Streets Of Boston]

Yes, you're right about that. Calling notifyDataSetChanged on the adapter is 
the best way to go and you should use it in 99% of cases. However, in some 
cases rules should be broken. :)
A call to notifyDataSetChanged redraws all the children in the ListView and 
is relatively expensive and you get the side effects you notice in your 
example (touch issues).
In this case, another solution may be necessary, where visible list-items 
(child-views of the ListView) or their children update *themselves*.
You could do this by tagging list-item views (contentView-s) by calling 
setTag an do a getTag on all the ListView's child-views to be able to find 
them back when they need updating.

I continue to disagree with this.  First of all, the ListView should
only be redrawing what is visible on the screen.  That is why the
Adaptor has a getView(int position...) method, so that the ListView
can be smart about which views it needs to redraw.  Second of all, the
children VIEWS should not be responsible for updating themselves when
the underlying data changes.  This is precisely why the ListView's
Adaptor has a notifyDatasetChanged!  So that you can give a hint do
the ListView that the data has changed, and so that it can ask for the
Views it needs to update.  the getView() method on Adaptor also has a
"View convertView" arg so that it can pass the getView() method a
recycled view to update.  At the very worst, Adaptor needs to be
updated to have a "notifyDatasetChangedAtIndex(int[] indexes)" method
so that the ListView can be even smarter about which row(s) to
redisplay (instead of redisplaying the visible rows as it currently
does).  In any case, I just don't see why my VIEW code should be smart
about updating itself when the underlying data changes; in other words
isn't that what the Adaptor is supposed to do for me?

Re: [android-developers] Re: Flaky Touch Screen on Nexus One

[Dianne Hackborn]

I'm not sure what more to say except that this isn't how
notifyDataSetChanged() is supposed to be used.  It is for relatively
infrequent, significant changes to the underlying data.  The typical case is
when a new query has been done in a database and the adapter is being
switched to show the data of the new cursor.

I understand that there is apparently some API on iOS that sounds similar
and is what you use, but for what you want to do this is not appropriate on
Android.  iOS != Android.

Nobody has yet explained to me how calling notifyDatasetChanged()
relatively frequently would cause "touch issues".  I am calling
notifyDatasetChanged() from the main/UI thread.  The touches are
coming in and being processed from the main/UI thread.  No touches
should be lost.  Period.  When the main/UI thread is busy handling a
touch, it should do just that; handle the touch.  Nothing else in my
code could possibly be interfering with this because my code is also
running on the main thread.  My data processing code is running in a
background thread, but that does nothing worse than notify the main
thread in a variable that it may elect to pop data off the data thread
if it wants to on a later event loop.

Let me simplify this.  Do you know of a Google example code you could
point me to that shows a ListView with many items updating itself,
without calling notifyDatasetChanged()?  Where the items in the list
are updating in real time?

How is my View code supposed to know which list items are visible?
Why should I be responsible for updating the cells if they aren't even
on the screen?  I'd need a pointer to all of the ListView subviews.
Why isn't there simply a method on Adapter named,
notifyDatasetChangedAtIndexes(int[] indexes), so that the ListView can
be smart about merging the changes that I tell it about, with only the
cells that are currently visible?

Figuring out which items are visible is pretty easy, you can use
ListView.getFirstVisiblePosition() to know what section of your adapter is
visible (getFirstVisiblePosition() + getChildCount() - 1 gives you the last
visible position.)

Ok.  So are you also agreeing that I should NOT be calling
Adapter.notifyDatasetChanged() to have the ListView automatically
refresh itself?  And I should be updating the data in the cells myself
behind the scenes when individual data changes (but the overall
dataset count remains the same as before)?  If so, this is complete
news to me.  This completely defeats the purpose of having an Adaptor,
and breaks the MVC paradigm.  The only thing I should have to do in my
code is tell the Adaptor that my dataset has changed, and the view
should redraw accordingly.  Adaptor should have a
notifyDatasetChangedAtIndexes(int[] indexes) at the very least, rather
than force the developer to update the cells manually.  I guess I'm
surprised Google is indicating the need for manual updates of data in
the cells.

Re: [android-developers] Re: Flaky Touch Screen on Nexus One

[Romain Guy]

notifyDatasetChanged() is used to force ListView to invoke Adapter.getView()
again, which may be expensive, depending on what you do in it. ListView does
have many optimizations to make notifyDatasetChanged() calls as efficient as
possible though.

If you are doing *very* frequent updates (several times per second for
instance, with let's say a progress bar or some sort of animation) you
should indeed modify the Views directly.

Adaptor should have a

It doesn't really matter, it wouldn't be more efficient to update cells that
are already on screen. It would only matter when you update cells that are
not displayed. That said you can easily just not invoke
notifyDatasetChanged() if you are updating cells that are not between
getFirstVisiblePosition() and getFirstVisiblePositon() + getChildCount().

My main point is that there is already a model-view-controller style
Adaptor in place to handle the mediation between the data and the
view, and so I would rather not have to update the View(s) directly
myself.  I would rather just write my Adaptor accordingly, and have
the data-side tell it when there are fresh changes to display, and
then have the ListView decide if/when it should act on those changes
(hence the notifyDatasetChangedAtIndexes()).

[android-developers] ViewHolder paradigm vs. using View.setTag()

[Eric]

In the Google I/O 2010 - The world of ListView talk shown here:

http://www.youtube.com/watch?v=wDBM6wVEO70&t=17m38s

a 'ViewHolder' paradigm is suggested to cache views and avoid the
findViewById lookup.  Could the same thing be achieved by using the
setTag(id, Object) method on View, and simply use the View's tag map
to store the reference by resource ID?  I think this would work, but
would it introduce any memory leak (or other) problems?


public static final View getCachedViewByTagId(View parentView, int
viewToFindId) {
Object object = parentView.getTag(viewToFindId);

if(object == null) {
object = parentView.findViewById(viewToFindId);

if(object != null) {
parentView.setTag(viewToFindId, object);
}
}

return (View)object;
}

Re: [android-developers] ViewHolder paradigm vs. using View.setTag()

[Romain Guy]

You could, but setTag(int, Object) forces you to use unique ids throughout
your app.
