Ok, thats what I wanted... It works perfect...
One last question: When I store/set for example a boolean value to my
sharedprefences object checkbox1...
Ist this value stored until I deinstall this app?

[android-developers] Button Animation

hi
I have a problem with an animation of a button.
I would move and fade a button from a origin position to another
position. well i created a translate animation and fade animation, i
start the animation with the follow code:

AnimationSet exchangeAnimation = new AnimationSet(true);
exchangeAnimation.setFillAfter(true);
exchangeAnimation.setAnimationListener(new AnimationListener() {
  public void onAnimationStart(Animation anim)
{button.setEnabled(false);}
  public void onAnimationRepeat(Animation anim) {}
  public void onAnimationEnd(Animation anim) {
  button.setEnabled(true);}});
exchangeAnimation.addAnimation(AnimationHelper.fadeAnimation(0,
1, 2000));
//i valori passati come fromX, toX, fromY e toY sono dati da un
rapporto e vanno da 0.0F a 1.0F
//quindi bisogna calcolari come pos voluta / width screen o
height screen

exchangeAnimation.addAnimation(AnimationHelper.translateAnimation(0.0F,
0.5F, 0.0F, 0.5F, 1500));
button.startAnimation(exchangeAnimation);

So, my problem is that while the button moves to the position that I
want, the hit area remains at the point of origin.

somebody can help me on how to correctly position the hit area of the
button?

[android-developers] Re: major problem with network location fixes and their timestamps

2011-10-14 Thread Mathias

I thought that

It seems as though the Location.getTime() sometimes isn't accurate,
in
that the system under certain circumstances just updates the time of
an old fix and passes it on as though it was new. For us, this is very
unfortunate. 
and
I *need*
recent fixes, and for that i need to know how old the fix is. I
therefore utilize location.getTime() against the
system.currenttimillis to see how old it is. 

Describes my problem.

As for your answer it really a long discussion, but short answer is
that i do listen for it but gps often takes long time, user might have
turned off and it doesn't work indoors.

This problem is about the network provider, as i wrote. I appreciate
any feedback, so thanks.

2011-10-14 Thread Mathias

As mentioned in another reply and in my original post, this issue is
about the network provider. My app can't wait forever, user sometimes
has gps turned off and it doesn't work indoors. When i DO get a GPS
fix, it works fine.

Thanks for feedback mate.

 Can't say that I've seen that before. I've only used the GPS a small to

 Is the GPS hardware not able to get a fix and causing your logic to drop
 back to the network GPS?  If so, it might be that.

 Is it happening on multiple different devices and how many devices have you
 tested it on?

 You might want to check out the GPS Status app on the market and see if it
 gets a fix. If it does, it will tell you the time it got it and other
 information about the fix.  Good way of testing the hardware and see if you
 have an issue there.

  Hi, if someone could bear with me on this one i'd be most happy since
  i'm really disillusioned right now.

  BOTTOM LINE (to be detailed further down):
  It seems as though the Location.getTime() sometimes isn't accurate, in
  that the system under certain circumstances just updates the time of
  an old fix and passes it on as though it was new. For us, this is very
  unfortunate.
  I think it has something to do with this logline (again in more detail
  below):
  10-12 16:34:47.186: DEBUG/LocationMasfClient(1188):
  getNetworkLocation(): Returning cache location with accuracy 1072.0

  From what i can see, the same location is returned over and over
  again, just with its timestamp overwritten...

  EXPLANATION:
  Have an app that queries location. I register both network and gps,
  wait for a certain time and takes what comes back from either one and
  unregister both. Before i register i check the latestknown location
  and use that if it's not too old.

  All works fine, process wise, but there's one major issue. I *need*
  recent fixes, and for that i need to know how old the fix is. I
  therefore utilize location.getTime() against the
  system.currenttimillis to see how old it is.

  However, we see in certain scenarios, that the fix coming back, with a
  recent timestamp (often under a second!) is for a location where we
  know that the phone hasn't been at for over 30 minutes!

  LOCATION PROCESS EXPLANATION WITH LOG DETAILS:

  One VERY interesting thing can be seen by examining the debug log of a
  typical positioning process in my app:

  1. first we check the latest known location:
  10-12 16:34:47.166: DEBUG/nubaLocationService(6774):
  getLastKnownLocationForProviderWithinTimeSpan;now;1318430087165;time;
  1318429486221;nowDate;Wed Oct 12 16:34:47 Europe/Stockholm
  2011;timeDate;Wed Oct 12 16:24:46 Europe/Stockholm 2011;age;
  600944;TooOld;true;tooBadAccuracy;true;lat;59.3267657;lon;
  18.0428283;accuracy;1072.0

  here you can see that the age about 60 seconds, my upper limit is 30
  seconds, so i will discard it and register for live updates:

  2. register for location listening:
  10-12 16:34:47.166: DEBUG/nubaLocationService(6774): requesting
  network updates
  10-12 16:34:47.166: DEBUG/NetworkLocationProvider(1188):
  addListener(): com.karpet.nuba.android
  10-12 16:34:47.166: DEBUG/NetworkLocationProvider(1188): setMinTime: 0

  3 NetworkLocationProvider log entries and onLocationChanged callbacks:
  Now HERE is something very interesting:
  10-12 16:34:47.186: DEBUG/LocationMasfClient(1188):
  getNetworkLocation(): Returning cache location with accuracy 1072.0
  10-12 16:34:47.196: DEBUG/NetworkLocationProvider(1188):
  onCellLocationChanged [142,9307015]
  10-12 16:34:47.216: DEBUG/nubaLocationService(6774):
  onLocationChanged();new bestLocation! now;1318430087220;time;
  1318430087178;nowDate;Wed Oct 12 16:34:47 Europe/Stockholm
  2011;timeDate;Wed Oct 12 16:34:47 Europe/Stockholm 2011;age;42;lat;
  59.3267657;lon;18.0428283;accuracy;1072.0;oldnull?;true

  It says returning cache location, with the exact same accuracy, lon,
  lat, but CHANGED time!

  4. We listen for 25-30 secs, but nothing more comes back, so eventually
  we unregister:
  10-12 16:35:14.216: DEBUG/LocationManager(6774): removeUpdates:
  listener = com.karpet.nuba.android.service.LocationService
  $NubaLocationListener@4582cb78

  I have no idea why this happens, but sometimes we can start and stop
  our listening for quite a while, 20-30 times when we've travelled
  quite far, to another cell tower, but still get old fixes as new
  callbacks!

  Help/Pointers would be extremely appreciated!

people positions in real time over maps. The application is not for
comercial use. It will only be used by a selected number of users that

 Restore your keystore from your backup. If you do not have a backup of

2011-10-14 Thread MobileVisuals

The morphed positions for the stars are calculated from some
precalculated 3d arrays, one 3d array for each single galaxy shape,
like below.
positionsM1 and positionsM2 are the two 3d arrays, which get morphed
for this frame. The result is the new morphedPositions array, which is
drawn later. I can't find any frame-to-frame coherency here. I am
considering to start with another 3d animation instead, which doesn't
use morphing, because I don't have a clue how to make an effective and
fast sorting algorithm for this:

for (int i = 0; i  morphedPositions.length; i++) {
morphedPositions[i] = (morphcount * positionsM1[i]) * 
mlInv
+ ((morphLength - morphcount) * 
positionsM2[i]) * mlInv;
}

Let Android handle it.

Just create a second layout folder called layout-land and put all
your landscape layouts in. The layouts must have the same file name
like the layouts in the normal layout folder for portrait mode.
Android will pick the right folder to get the layout from. On
landscape mode it will take the layouts from the layout-land folder
and in portrait mode it will take the layouts from the layout
folder.

Thanks Flo for quick reply.

In my case the landscape layout files have no changes they are as same
as portrait, that's why i haven't created a separate landscape folder
for layout(layout_land). So on change of orientation the android will
pick the file from layout folder only.

My confusion shall I handle onConfigurationChange for orientation
which will stop android to create a new activity or i should not
handle onConfigurationChange and let android do the life cycle process
complete.

Re: [android-developers] Re: android.text.format.DateFormat.format performance

Thanks Steven! I will try that.
As Date.getHours() etc. methods are mentioned as deprecated. I will check
with Calendar class as well if it is still faster than DateFormat.

Thierry.


2011/10/14 Studio LFP studio@gmail.com

 It is slow and so is String.format(). I've been messing around with it a
 bit and here is a *rough *sample I tested:

 private static final String DATE_AM_PM[] = { am, pm };
 private static Date dFormat = new Date();
 private static int iHour, iAMPM;

 public static String formatDate( long lTimestamp )
 {
 dFormat.setTime( lTimestamp );
 iHour = dFormat.getHours();

 if( iHour == 0 ) { iHour = 12; iAMPM = 0; }
 if( iHour == 12 ) { iAMPM = 1; }
 else if( iHour  0  iHour  11 ) { iAMPM = 0; }
 else if( iHour  12  iHour  24 ) { iHour -= 12; iAMPM = 1; }

 return dFormat.getMonth() + / + dFormat.getDay() + / +
 (dFormat.getYear() + 1900) +   + iHour + : + dFormat.getMinutes() +
 DATE_AM_PM[ iAMPM ];
 }

 As I said, it is rough and doesn't even format the output fully.

 I tossed this in my application and used it a bit for a speed test and this
 takes up half the time as the formatting routines do. Funny thing is, it has
 nothing to do with the date part. It seems the formatters are using a
 StringBuffer and some replace functions in the StringBuffer and that is what
 is slowing it down.  I may try to work up a JNI replacement and see if some
 sprintf or fprintf action fix the issue but it may not because of the extra
 layer.

  android.text.format.DateFormat.format(kk:mm,endTimeMilli));
 
  So just curious: Is there any more efficient way to transform a
  timeMillisecond time to a date string (in my case hour/minute)?

[android-developers] Any problems regarding LVL when moving apps from one Google account to another?

2011-10-14 Thread Mark Carter

I tried asking this question over on Android Discuss but unfortunately 
didn't get any reply:

http://groups.google.com/group/android-discuss/browse_thread/thread/5598e3682828d3db

To summarize: LVL signs responses with your public key (as given in the Edit 
Profile of your Developer account). So what happens when you move an app 
from one account to another?

If LVL uses the new public key then the existing app installations will all 
fail their LVL checks!

Has anyone got experience of moving an LVL (or in-app billing) app to a 
different Google account?

It is the only way. I would not be the least bit surprised to find
this undocumented/unsupported provider locked down in the future the
way they recently locked down Gmail. I am hoping they don't -- I'm
really hoping this provider gets formal SDK support someday.

Also, there is no guarantee that this provider exists on any given

[android-developers] animateWithDuration

2011-10-14 Thread bob

I'm converting an app from iphone to Android.  On iphone there's a
function called animateWithDuration that makes it easy to fade in UI
stuff and slide in UI stuff.  For instance, this fades some text in…
then out:


  [UIView animateWithDuration:0.3 delay:0 options:0 animations:^{
[notification_ setAlpha:1.0];
  } completion:^(BOOL finished) {
if (!finished)
  return;
[UIView animateWithDuration:0.3 delay:2.5 options:0 animations:^{
  [notification_ setAlpha:0.0];
} completion:^(BOOL finished) { }];
  }];


Is there any kind of Android equivalent?

Thanks.

[android-developers] Re: Android cocos2d game development

2011-10-14 Thread Oli Wright

While I agree that Google is your friend in this case, to save you that 
minimal effort I can point you towards two possible options:

http://www.cocos2d-x.org/
http://code.google.com/p/cocos2d-android-1/

Go on there and read any wiki and tutorial material they have, and review 
any code examples they have in their repositories.  This isn't really the 
place to guide you through starting with either of those so I suggest you 
seek help from their respective user communities.

If you're completely new to Android then I would recommend starting with the 
android dev guide (http://developer.android.com) to at least get you to 
understand the core system a bit better before you start playing with cocos.

[android-developers] Re: Best approach for onConfiguratinChange()

There has been a decent amount of conversation on this subject and there's 
no right answer. Regardless of which way you pick, make sure you 
understand the pros and cons.

If you let Android do the work for you, make sure you understand that your 
application can be killed off and restarted at any time just by the user 
rotating the phone, docking, pulling out a hardware keyboard or game pag, 
etc.. There are quite a few times this can happen, so it would be best to 
know when it is going to happen and make sure your application is prepared 
to deal with it at any time.

If you decide to handle the changes yourself with configChanges, you only 
need to handle the changes that impact your application. If you use the same 
layout for both portrait and landscape, you don't need to handle rotation 
changes or hardware keyboard/game pad events. Only catch the ones that will 
impact your application.

Check out the configChanges documentation:

http://developer.android.com/guide/topics/manifest/activity-element.html#config

Each of the events listed there is a time where Android will stop and 
restart your application if you let it handle the changes. There may be more 
that aren't documented there, but those are the major ones. If you decide to 
handle them yourself, those are also the events you have the option of 
handling if they impact your application. Again, you will only need to 
handle the ones that would cause a change in your application, the others 
can be ignored.

Based on an application I wrote that checks all the activities in the system 
(including the built-in apps), about 50% use configChanges and about 50% let 
Android handle it (on both tablets and phones), so the choice is up to you. 
Regardless of which way you pick, make sure to do the necessary testing.

 In my case the landscape layout files have no changes they are as same

 for layout(layout_land). So on change of orientation the android will 
 pick the file from layout folder only. 

 My confusion shall I handle onConfigurationChange for orientation 
 which will stop android to create a new activity or i should not 
 handle onConfigurationChange and let android do the life cycle process 
 complete.

  Just create a second layout folder called layout-land and put all

  like the layouts in the normal layout folder for portrait mode. 
  Android will pick the right folder to get the layout from. On 
  landscape mode it will take the layouts from the layout-land folder 
  and in portrait mode it will take the layouts from the layout 
  folder.

[android-developers] Should ro.EMPTY_APP_MEM always be same as arguments in write /sys/module/lowmemorykiller/parameters/minfree

setprop ro.HEAVY_WEIGHT_APP_MEM 4096

should always be synced with  write /sys/module/lowmemorykiller/
parameters/minfree 2048,3072,4096,6144,7168,8192

What I still do not fully understand is why does init.rc script write
the values to the property service. I did a searched over the complete
Android source tree for these keys (FOREGROUND_APP_MEM,
VISIBLE_APP_MEM, ...) but the only occurances I found were in
com.android.server.am.ActivityManagerService.java  where they are
read into final int fields which seem to be never referenced anywhere.
Then What is the need from getting those properties in first place.

[android-developers] Re: Multiple Display suport

If you download the add-ons for other devices through the Android SDK 
Manager, you can usually find samples that come with them. If you look in 
the directory where you have the Android SDK, you'll find an add-ons 
directory. That should be where things like the LG 3D, KYOCERA multi-screen, 
Sony EDK, etc. are found. They may or may not have documentation or samples 
in there. Most manufacturers have a developers site you should check out to 
see if there is more documentation/help.

[android-developers] Re: EAAccessory Class in Android

Based on the documentation for the EAAccessory Class on Apple's site, there 
is not a single object like that in Android.

Android gives you different classes based on the type of device you are 
wanting to connect to. Built-in things like Bluetooth, GPS, sensors and the 
likes are in packages that relate specifically to them.

As of 3.1 you can also access USB connected devices (and even make your own 
with Open Accessory). See this link for more information:

http://developer.android.com/guide/topics/usb/index.html

You can pretty much get access to anything you want, just look for the right 
way to talk to them in the development site:

[android-developers] Re: how to insert image into listview and text also in list view

2011-10-14 Thread Jeremy Dagorn

Hi,

Look at this :
http://developer.android.com/reference/android/widget/ListView.html

So the process is simple, create a layout containing your list view
element.
Create another layout called listview_raw for example, which will
contain an imageView and a textView.

You have to create an Adapter, (ArrayAdapter, CustomAdapter, as you
want), in charge put the line with your image and text in the
listView.

For that, you have to implement the getView method of your adapter,
and set your adapter on your listView.

Here is the reference for all these components :
 http://developer.android.com/reference/android/widget/ListView.html
 http://developer.android.com/reference/android/widget/Adapter.html


Have fun,

[android-developers] Re: Camera application

2011-10-14 Thread mjmeyer

Without any logcat output or code as Fina suggested, I'd guess that
you are setting a some specific camera parameter value that a
particular model just doesnt support.

There are wide ranges of camera hardware out there and I see many
people do things like assume that 640x480 preview sizes are available
on all devices, which is not the case.

You need to use things like
Camera.Parameters.getSupportedPreviewSizesgetSupportedwhatever
and select a value that the device youre running on actually supports.

But, again, that's just a guess based on what I see lots of other
folks running into. Without code or log output it's hard to tell what
your issue might be.

 If you aren't, try using transactions:

Thanks Steven, I have implemented transactions and it runs about twice as
fast but still have to wait a somewhat
smaller fraction of a second.

As to the connection it's only opened once and shared across intents. The
queries are based on primary keys
so I do not see the need to have separate indices.

I think what is slowing things down could be the fact that I am reading
every single row of every single table just to
be on the safe side although things could be done more efficiently but at
the risk of complicating the code and
introducing bugs in the code. As to implementing the database calls in a
separate thread, the reason I didn't do it is
that the calling activity needs to display the data from the popped activity
retrieving it from the database to make sure it's
data remains consistent with the database. But it's true, I could store the
data in the database in a separate thread and only
read it when the application starts, and just write to it asynchronously.
This would really make my app faster. Or I could display a
progress bar in between operations. I just want to ensure my objects are
always in sync with my database so I
have a soreAndRetrieve() data method to make sure this happens at the
expense of speed, so maybe it's my
own problem.

Thank you for all your replies,

Regards,

John Goche

Re: [android-developers] Re: please help: broadcast receiver does not execute code

2011-10-14 Thread John Goche

Hi,

No, it's definitely skipping it because the intent is launched. Isn't that
strange?
Seems like broadcast receivers behave somewhat oddly in general, like when
I was sending it a parcel instead of a bundle and it would not run properly.

I had to move the alarm setter code into the launched intent to get it to
run.
Seems really strange.

Thank you for your help and interest,

John Goche

 Hello,

 I am having the following problem and was wondering whether
 anyone here could be so kind so as to help me. I am having a
 broadcast receiver in my code that opens a database and sets
 an alarm. However the code that sets the alarm is never called
 as shown in the adb logcat output. What is interesting is that the
 application does not crash but the intent that is called after the
 alarm setter was supposed to be called is run. So the intent
 that is launched after the alarm was supposed to be set is
 called even though I see no debug output telling me that
 the alarm setter function is called.

 Any ideas as to what is going on?

 (please see code below)

 Thanks,

 John Goche

 public class AlarmReceiver extends BroadcastReceiver {

   @Override
   public void onReceive(Context context, Intent intent) {

 Log.d(AlarmReceiver, received);

 // retrieve database handle

 DB db = DB.db(context);

 // retrieve data from database

 Globals.data = db.getData();

 // reset alarms (seems like this does not get called)

 Log.d(AlarmReceiver, Calling alarm setter...);
 AlarmSetter.doSetupAlarm(**context);
 Log.d(AlarmReceiver, Done.);

 // start new intent (this actually starts up for real)

 Intent i = new Intent(context, AlarmExpiredActivity.class);
 i.putExtra(alarmMessages, intent.getBundleExtra(**
 alarmMessages));
 i.addFlags(Intent.FLAG_**ACTIVITY_NEW_TASK);
 context.startActivity(i);

   }

 }

 class AlarmSetter {

   public static void doSetupAlarm(Context ctx) {

 Log.d(AlarmSetter, doSetupAlarm called.);

// ...

 }

 D/AlarmReceiver( 3805): received
 I/ActivityManager(   61): Starting: Intent { flg=0x1000
 cmp=com.bar.foo/.**AlarmExpiredActivity (has extras) } from pid 3805

[android-developers] Still time to save $400 on AnDevCon II Nov 6-9.

2011-10-14 Thread Nathan

I will be speaking at AndevCon II, Nov 6-9, on the subject of 'Marketing for 
Independent Android Developers. You can save $200 on the price of the 
conference by using the discount code 'Mellor', and another $200 for 
registering by October  21st.

http://www.andevcon.com/AnDevCon_II/registration.html

Using the code does not mean you have to come to my session; there are five 
or so others at the same time. There are 50 or so classes total. I went to 
the last AnDevCon, paid full price, and learned enough to make it worth it. 
There are people speaking there that are much smarter than me, including 
some you will recognize from this forum. 

If interested, sign up today. Don't wait until Oct 21st, because it is not 
only more expensive, but it will probably be sold out by then - it sold out 
last time. 

Have fun on all your Android projects!

[android-developers] SIP Registration problem.

2011-10-14 Thread Lakshman Bana

Hi,
I'm having two problems with SIP in android 2.3.3

1.) If I call setPort on SIPProfile.Builder then my To and From
headers is constructed with portnumber.
 example:
 sip:12223334...@open-ims.test:4060

 When SIP REGISTER goes to OpenIMSCore platform it could not
handle it. I haven't read the RFC-3261 completely
 but I don't see any examples referencing it as above for To and
From headers.

 If I send REGISTER message with To and From header as
sip:12223334...@open-ims.test then it works fine (not completely
 ran into problem-2).

2.) AuthUserName is not able to set in 2.3.3.

 I found a link where Android SIP developer mentioned that it is
available in 2.3.3 but not sure what I'm missing.
 
http://www.onsip.com/blog/leo/2011/01/05/our-evaluation-of-android-gingerbreads-native-sip-calling-with-the-nexus-s

 The document says setAuthUserName is available in API level 12.

At least I have work around for 1 but 2 is a blocker for me.

Any pointers would be a great help...
thanks

 What I still do not fully understand is why does init.rc script write
 the values to the property service. I did a searched over the complete
 Android source tree for these keys (FOREGROUND_APP_MEM,
 VISIBLE_APP_MEM, ...) but the only occurances I found were in
 com.android.server.am.ActivityManagerService.java  where they are
 read into final int fields which seem to be never referenced anywhere.
 Then What is the need from getting those properties in first place.

Re: [android-developers] sorting the listview

2011-10-14 Thread Subin Sebastian

@Vani,

It is not clear that what data you are adapting to the ListView. Anyway, use
some standard algorithms to sort yourData by date just before a line
something like this in your code appears.

yourListView.this.getListView().setAdapter(new
yourAdapter(yourListView.this, R.layout.your_row, yourData));

Hope that helps.

I discovered the error, with some help from StackOverflow. Make sure you 
didn't forget to put android: in front of targetSdkVersion in the 
manifest. That was my error.
