[android-developers] Re: Anyone used performHapticFeedback()?
Currently there is only a definition for long press, so this API isn't all
that useful. (This is also why the preference is hidden away in SpareParts,
it's not really ready for prime time.) If you are giving feedback for a
long press, then you may want to use it... but if you also feel the need to
have it ignore the preference, then please consider having your own
preference in your app since some users really dislike this stuff.

No, it is not possible, nor is it desirable -- the in-call screen does a lot of special stuff to provide a UI that works well when you are actually talking on the phone (not being impacted by false touches and such).

[android-developers] Cannot write SharedPreferences after update!! Help!
Hello, I'm trying to prepare an update to one of my apps and I just realized that the updated version cannot read or write over the previous version's SharedPreferences. Some details: * I'm using the 1.6 SDK and compiling for 1.5.3. * My androidmanifest.xml does not have a sharedUserId (I didn't think I need one if I was not sharing data between different apps). How to reproduce: * Install my current app from the market * Run the app * Exit and save the setting - invoking SharedPreferences Editor commit (it's using MODE_PRIVATE) * Now install my new update (via a browser download) * Run the app * Everything works fine * Exit & Save *** Now reboot the phone * Run the app again ==> Can no longer access old data or write over it!! Did I do something wrong? Is it because of the sharedUserId thing? Is it because of the way I'm testing - via market then browser? Why is LogCat reporting a UID change? ==> mismatched uid: 10031 on disk, 10046 in settings; Can I recover from this? I don't want to delete all of my users' data. help! =] Here's some edited output from LogCat: 09-28 09:10:54.083: ERROR/PackageManager(60): Package com.my.application.package.path has mismatched uid: 10031 on disk, 10046 in settings; read messages: 09-28 09:10:54.083: ERROR/PackageManager(60): Read completed successfully: 71 packages, 7 shared uids 09-28 09:11:08.513: ERROR/ApplicationContext(60): Couldn't create directory for SharedPreferences file shared_prefs/wallpaper-hints.xml 09-28 09:11:51.522: ERROR/ApplicationContext(278): Couldn't rename file /data/data/com.my.application.package.path/shared_prefs/ MyFuzzleFile.xml to backup file /data/data/ com.my.application.package.path/shared_prefs/MyFuzzleFile.xml.bak 09-28 09:11:51.552: ERROR/ApplicationContext(278): Couldn't create directory for SharedPreferences file /data/data/ com.my.application.package.path/shared_prefs/MyFuzzleFile.xml 09-28 09:11:51.552: ERROR/ApplicationContext(278): Couldn't rename file /data/data/com.my.application.package.path/shared_prefs/ MyFuzzleFile.xml to backup file /data/data/ com.my.application.package.path/shared_prefs/MyFuzzleFile.xml.bak 09-28 09:11:51.552: ERROR/ApplicationContext(278): Couldn't create directory for SharedPreferences file /data/data/ com.my.application.package.path/shared_prefs/MyFuzzleFile.xml Thank You!

[android-developers] Re: ADC2: Low volume of judges
I think there is a huge number of apps submitted in this contest and sorting out the best is a huge work... that for once has been given to the users ! This is a great opportunity for us, but it also shows us that every app developer can't be the best. The notes we have to give to apps are quite clear about what a winner could be : - it has to be an original concept - it has to use the specific features of the android platforms - it has to look good - it has to be universally useful to all of the reviewers Based on this, it's quite natural that applications that are not working right, are too specifically oriented to a subset of the population (religion, geography) will get eliminated on first round. If most of reviewers skip 80% of the submitted apps, this is because they, from the beginning, would not get a good mark on the "utility" line. I have really tested maybe a dozen apps for the moment, and most of them did not reach more than 2 stars in every line, because they are not working, are one version of a concept among a hundred similar implementations, or because they don't answer MY needs. This is true for every other revewers, and it has to be like this if we really want to see emerging the real best apps. There is no place for poor apps, this is a contest for really outstanding apps that will show all the power of the android platform against the others. So, even if after this round only a dozen of apps get high rates, I think these apps will really be the ones that will deserve it and it's allright ! It might be sad for developers who spent a lot of time in coding their apps and do not get many reviews, but... hey, wake up ! this means your app is either not good enough or too specific (and this does not mean it is bad !).

[android-developers] Re: Can't i call a service function in activity's onStart/onCreate?
You need to wait until you actually receive the service connection
callback before you do anything with the service. You can't simply
assume that the callback has already happened when you reach your
onStart.

[android-developers] Re: Anyone used performHapticFeedback()?
This one works for me:
performHapticFeedback( HapticFeedbackConstants.LONG_PRESS,
HapticFeedbackConstants.FLAG_IGNORE_GLOBAL_SETTING );
I remember having trouble getting other things to work.
Fortunately I only use Haptic Feedback with a long press, otherwise
the Code Cops might come calling.
If really want to be hauled in front of a judge you can use the
Vibrator service directly.

[android-developers] Re: Intent.putExtra (String name, String[] value) caching old value
Okay I found out what was happening. It was actually two things:
1) Was not editing the data used inside a PendingIntent.
Changing the flag in the PendingIntent.getService(...) method to
FLAG_UPDATE_CURRENT solved this. However this led to the second
problem.
2) A new PendingIntent is not always created with each call to
PendingIntent.getService(...).
If the arguments to that call match then the method will return an
existing PendingIntent that matches to be used. I think Android is
trying to be smart about reusing resources. The only argument the
method doesn't check when deciding to reuse an existing PendingIntent,
or provide a new one, is the Intent itself.
This posed a problem for me, because my activity needed to send
multiple PendingIntents, each using an Intent with the same Class but
different extended data for the Intent. All of the PendingIntents
needed to be active at the same time. For example, one PendingIntent
needed to go off 8 minutes from now, while another PendingIntent
needed to go off 10 min from now. If the first PendingIntent was
already sent to the AlarmManager, once I tried to make a new
PendingIntent for the 10 min delay, it would grab the Existing
PendingIntent, and change it instead, essentially now only providing
one Active PendingIntent.
Unfortunately as of right now there are no flags you can pass to a
PendingIntent that will force the method to provide a brand-new
Pending Intent, i.e. don't try to match the arguments to an existing
one and return that one. However I found a "hack" solution right
now. The int requestCode parameter used in the
PendingIntent.getService(..) is not used right now according to the
documentation, however, it is still checked by the method to decide if
there is a matching already existing PendingIntent out there. So my
hack solution is to just provide a new dummy requestCode every time I
call the PendingIntent.getService(...), which creates a mismatch in
parameters, it doesn't find an existing PendingIntent with that
requestCode, and gives me a new one. My app is now doing exactly what
I want. This is a hack though, because if the requestCode is ever
used in the future, this might mess things up.
I propose that in the future the PendingIntent.getService(...) method
should have a flag that forces a new pending intent to be created,
e.g. FLAG_CREATE_NEW. The FLAG_ONE_SHOT doesn't quite do this, since
if the first PendingIntent hasn't actually been used yet, and you try
to create another one to be used later, it will match and grab the
first and modify it, effectively getting rid of the first logical
PendingIntent that would have been used.

[android-developers] Can't i call a service function in activity's onStart/onCreate?
My activity bind a service. I want to call the service's function in
actitity's onStart/onCreate function, but it doesn't work.
The service started suncess but the connection is null.
When I just call the service's function in other function (onClick for
example), it works well.
thanks for help.
here is my code:
public class AidlTest extends Activity
{
private static final String TAG = "AidlTest";
IAidlService mService;
private OnClickListener mCorkyListener = new OnClickListener() {
public void onClick(View v) {
test();
}
};
private ServiceConnection mConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className, IBinder
service) {
mService = IAidlService.Stub.asInterface(service);
}
public void onServiceDisconnected(ComponentName className) {
mService = null;
}
};
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
TextView v = new TextView(this);
setContentView(v);
v.setOnClickListener(mCorkyListener);
Log.v(TAG, IAidlService.class.getName().toString());
Intent intent = new Intent(IAidlService.class.getName());
bindService(intent, mConnection, Context.BIND_AUTO_CREATE);
}
@Override

Okay, thanks! I wasn't sure how the SavedState object was being

[android-developers] MapView Overlays
My problem is my MapView becoming very laggy and so non-responsive at times, that Android thinks its hit deadlock and tries to close it. I am adding 60 overlays to the map view and i originally thought that the icon size may be causing the problem by using up all the memory. When i decreased the overlay icon size, it did improve things, though it is still to slow to be usable. Has anyone experienced anything similar and have a workaround? There may be a better way of doing it other then extending the Hello MapView example. Any thoughts welcomed.

[android-developers] Anyone used performHapticFeedback()?
I want to invoke the haptic feedback buzz when my ImageButton is
pressed, but I am not sure the best way to do it. I first checked that
my button was enabled for that, and isHapticFeedbackEnabled() returns
true.
Then I am calling performHapticFeedback() with the constant
FLAG_IGNORE_GLOBAL_SETTING, as the docs indicate that will be used to
override any global settings.
The doc is a little ambiguous, but it does imply that this is
something I can call at any time, so I am calling it in the
OnClickListener():
final ImageButton mybutton= (ImageButton) findViewById
(R.id.mybutton);
mybutton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
mybutton.performHapticFeedback
(HapticFeedbackConstants.FLAG_IGNORE_GLOBAL_SETTING);
// The rest of my code
}
}
);
I appreciate that it would be better to call it when the finger first
touches the button rather than on the Click event, but I wanted to get
it working to start with, before refining it.
Am I barking completely up the wrong tree, or should the above work
when I click on the button, because nothing happens?

"Restarted"? A running service will start running again, but to me "restart" implies it was destroyed and recreated, which does not happen. When the CPU shuts down, everything freezes in mid-operation. When the CPU starts up again, everything continues from where it was. Again, I strongly advise against having services run indefinitely.

Hi All, Is it a must for me to call startActivityForResult under my class than extends Activity? I'm struggling with my lab sheet. It's about Game of Life (http://en.wikipedia.org/wiki/Conways_life). The source code can be grabbed from here (http://filebeam.com/ 558274259ae956cb411897081ca1665b) Now I'm required to modified the code such that whenever I press the screen, it will start a new activity and prompt the user for input. Then the input is used to draw the points on the screen. The code is split into 4 parts, (GridView, GridDelegate, ViewDelegate and grid). ViewDelegate is the interface class. grid is the activity class. My problem is, how can I call startActivityForResult from GridDelegate? Because I m required to start a new activity whenever I pressed the screen, and the doTouchEvent(Event event) is implemented in GridDelegate. OR any suggestion for me, so that whenever I pressed the screen, I can start a new activity that ask the user for input? I've done defining the new Activity class that ask the user for input (following several tutorials online), but I m stuck here now. Please help me.

[android-developers] ADC2 - app World of Bombs
Hi all and especially to ADC2 testers. I wanted to inform i had to restart the world of bombs server while ADC2 users were connected. i apologize for that. I found also a bug when you lose so please win to not have a potential app crash which does not occur 100% but preferable to win. I can't modify the version of the server for now because it would be anymore compatible with the ADC2 client version. Anyway, i would like just thank you the testers which already tested and they are a lot. I just hope they have not encountered the bug, if so reconnect and don't be to hard with the game. don't judge that but the game itself since this bug will be corrected.

Not that I am aware of. Bear in mind that not all content providers will be using a SQL database as the place of data storage. Since the contacts content provider does appear to use SQLite, rather than iterating over your contacts, though, you could try the IN syntax in the WHERE-style constraint: [WHERE] person_id IN (...) where ... is a comma-delimited set of values, or possibly even a sub-select to get the IDs of the contacts to update. http://sqlite.org/lang_expr.html -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Looking for Android opportunities? http://wiki.andmob.org/hado --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Crossword Puzzle in Android
Hi All, Thanks for the advice from everyone. I've done a little bit of research, but I m not sure the idea of rendering the boxes with numbering is correct or not. Is it true that I can draw on a canvas? I m reading this tutorial http://www.anddev.org/the_pizza_timer_-_threading-drawing_on_canvas-t126.html It seems like after I draw a box, I can still draw on the same place, overlapping it. So I can do something like "drawing" the numbers on top of the boxes right? In face I'm not doing a crossword. It looks similar to crossword but it is called CodeCracker instead. I did a google on "CodeCracker" but the result it returns are mostly something else. Here are a few link on the "CodeCracker" I m saying: http://www.codecracker.co.nz/samples/samples.htm http://www.puzzco.com/knight%20features/interactive/samples/Interactive%20Samples/code-cracker.htm http://www.thepuzzlecompany.co.nz/samples/Interactive%20Samples/code-cracker%20extra.htm Regards Kwan On Mon, Sep 28, 2009 at 2:00 PM, Seth Mould wrote: > > Hi Kwan, > > I have a project on SourceForge called xW which seeks to establish a > standard XML format for word puzzles, so you might want to look at > that for your input.

[android-developers] Update all the contacts belonging to one group
Dear all, I have an application that updates all the contacts belonging to a group, I currently do the following : -> Get the group id -> Get all the contacts id inside this group -> For each of them I am doing an update on the contact => This is really heavy and seems to take time in real phones while I expect it to be "instantaneous". I am wondering if we can, in the ContentResolver.update() method specify a kind of join. For instance I'd like to do something like : UPDATE SET ="" FROM People p, GroupsMemberships gm WHERE p.person_id=gm.person_id and gm.group_id= Does anyone know if it's possible or not? The update method has got a "where" attribut but can we use this attribut for complexe requests ? * where A filter to apply to rows before deleting, formatted as an SQL WHERE clause (excluding the WHERE itself). *** Thanks to everyone for its feedback. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

You can see from the issue tracker (http:// code.google.com/p/android/issues/detail?id=1725) that there is much wailing and gnashing of teeth over this issue Keep up the great work on Android: I'm really looking forward to the Bluetooth API (I have great plans for an app which requires bluetooth which is why I'm anxious to know).

[android-developers] Re: trouble with programmatically adding mock location data
Here is the code using a mock location provider. Basically my question
is, why is the mock provider not returning the previously set mock
location correctly. See last comment in code:
private GeoPoint getUserLocation() {
LocationManager locationManager =
(LocationManager)getSystemService
(Context.LOCATION_SERVICE);
if (!PRODUCTION_ENVIRONMENT){
//Get some mock location data in the game
locationManager.addTestProvider(MOCK_PROVIDER_NAME,
true, false,
true, false, false, false, false, Criteria.POWER_LOW,
Criteria.ACCURACY_COARSE);
Location location = new Location(MOCK_PROVIDER_NAME);
location.setLatitude(32.64480);
location.setLongitude(-16.90967);
location.setTime(new Date().getTime());
locationManager.setTestProviderLocation(MOCK_PROVIDER_NAME,
location);
locationManager.setTestProviderEnabled(MOCK_PROVIDER_NAME, true);
}
//i just want an approximate location so no high expectations
here
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_COARSE);
criteria.setPowerRequirement(Criteria.NO_REQUIREMENT);
//this correctly retrieves the mock location provider
String provider = locationManager.getBestProvider(criteria,
true);
if (provider != null) {
//this is where the mock provider returns null ... why?
Location location =
locationManager.getLastKnownLocation(provider);
return new
GeoPoint((int)(location.getLatitude()*E6_LATLONG), (int)
(location.getLongitude()*E6_LATLONG));
}else return null;
}
Might this be a bug in the API?

As always, you are best served by talking to qualified legal counsel about legal issues like this. In this case, I would think "through your application" would mean literally "through your application" -- accepting payments in the app itself. That would not cover payments through a Web site, post office box, envelopes taped to the bottom of park benches, or other means of transfer.

There is no direct API for that as far as I can see. You may need to create a new ItemizedOverlay with the reduced set of marks, remove the old ItemizedOverlay from the getOverlays() collection, and add in the replacement. Or, you could try calling populate() again and see if that will clear and re-add all of the marks (minus whichever one you are trying to get rid of). -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Need Android talent?

hi,
it's called twice because two activities are created: first one lives
for a very short time - it's immediately onDestroy()ed.
i posted about this couple of months ago but nobody seemed to answer

Animations would > be great! :( or even better custom components... The issue is security. You can't have third-party code run in the home screen's process without introducing security holes, which is why RemoteViews exists in the first place. That pretty much eliminates custom components, at least as the term is traditionally used (i.e., things that would draw on a Canvas). Android has fairly consistently held to the pattern that security trumps all else when desires collide, and I for one am rather happy with that policy. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Need Android talent?

I'm skeptical that using radio buttons is the correct UI choice. Consider a couple of regular Buttons to launch your dialog(s) and an ImageView showing an icon indicating the user's choice, or something like that. The point behind common widgets, like radio buttons, is to make the user's life easier via a consistent experience. Users, when they see radio buttons, will expect standard behavior. The more you depart from that behavior, the more confused your users may get. Having a radio button pop a dialog, IMHO, is an unexpected behavior. Having a radio button pop a dialog, and then *not* have that radio button behave like a radio button (i.e., be selected) based upon your own rules, IMHO, is *really* unexpected behavior. If you want to stick with radio buttons, though, I suspect your current implementation is going to be about as good as it gets. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Need Android talent?

[android-developers] Does starting a query will notify content observer?
Hi,
I have called an AsyncQueryHandler's startQuery function with a
specified URL, will all the content observer observing that URL get
notified?
I asked this question because I don't understand how
RecentCallsListActivity's Delete All function works.
Here is the code, with comment:
case MENU_ITEM_DELETE_ALL: {
getContentResolver().delete(Calls.CONTENT_URI, null, null);
//TODO The change notification should do this
automatically, but it isn't working
// right now. Remove this when the change notification
is working properly.
startQuery();
return true;
It appears the call to startQuery() is a work-around to fix the
notification not working for the delete() case.
But the startQuery is merely calling AsyncQueryHandler's startQuery function.
mQueryHandler.cancelOperation(QUERY_TOKEN);
mQueryHandler.startQuery(QUERY_TOKEN, null, Calls.CONTENT_URI,
CALL_LOG_PROJECTION, null, null, Calls.DEFAULT_SORT_ORDER);
This won't trigger any changes in the Calls.CONTENT_URL. So how will
this extra call to 'startQuery()' fixes the notification problem
described in the comment?
Thank you.
