you should remove keyboardHidden . Result:
android:configChanges=orientation

 But still activity restarted each time when I change screen

[android-developers] Is there anyway to get to know, when an application has crashed or stopped completely?

[Durg]

Hi All,

I want to know, if there is any callback method/procedure to know when
a particular application has been crashed or stopped working
completely (thorugh code in any of the other applicaiton).

My use case :
First, i'm starting a watch dog application, which starts another
application internally (already installed application) by calling the
launcher activity of that.
Next, when the called application crashed/stopped due to some issue, I
want to start that application by calling it's launcher activity
again.

For this, could anyone please suggest me the correct procedure to do
this?

Thanks  Regards,
Durg

[android-developers] Re: On screen orientation changes activity restarted.

[pramod.deore]

Ok I had tried it but it doesn't work. Look I had developed one simple
application in that only I had print one line in onCreate method, but
each time when I change screen orientation that statement print (i.e.
which I had write in onCreate() method)

Here is my code

import android.app.Activity;
import android.content.res.Configuration;
import android.os.Bundle;

public class ActivityTesting extends Activity
{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
System.out.println (Inside onCreate);
}

public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
}
}


and xml file is like

?xml version=1.0 encoding=utf-8?
manifest xmlns:android=http://schemas.android.com/apk/res/android;
  package=com.micro.activity
  android:versionCode=1
  android:versionName=1.0

[android-developers] Google maps, Overlays and the shadow layer

[oriharel]

What can I do with the shadow layer of the the google maps overlays?
I tried, naively, to draw something (an arc) only when (shadow ==

I'm interested in drawing arcs and arc shadows on a map.
is there a nice google-maps way to do this?

[android-developers] Re: Disappearing Alarms

[mot12]

I have seen this on a number of devices if the phone is idle for a
long time or if the display gets shut off manually. My app has
~100,000 users so I am quite sure I am not imagining it. My phones (N1
and Galaxy) are not affected, but I get a lot of these reports from
Droid users.

Here's a simple test I would recommend:
- tell your users to set the stock alarm. If you experience the same
situation that I talk about, you will find the stock alarm fails, too.
- tell your users to keep the phone plugged in. Your alarm will no
longer fail.

If these tests show my experience is relevant to your problem, I have
a number of suggestions what else you can do.

[android-developers] Re: Is anyone's active install % dropping like a rock lately?

[Zsolt Vasvari]

I noticed the same thing.  Let me share a few stats for my app.

The active rate from 40% to a 32%, but at the same time the overall
rating has gone up a little bit, from about 4.22 to 4.33 as shown by
AppBrain, so the overall rating is more 5 stars than 4.

There isn't a single bad comment posted, literally everything is = 4
stars since the early problematic days when I had a few FC bugs.  I
get one rating for about 1 in 36 downloads and one comment in probably
1 in 100.

So it's either that 2 out of 3 people download my app and they don't
like it and uninstall it, but don't bother giving it a low rating or
comment, or that the install count is shown to be too high.

As I have mentioned it previously, as I am having a problem with my
app buried so deep into cr*p on the Android Market, that I actually
very surprised that as many people would discover it daily as they
do.  My app is doing much better on AppBrain placement-wise and it's
actually one of the top apps in its category and would most likely be
evaluated by people who are doing comparission shopping in this
category.

My gut feeling is that the download numbers on the Android Market are
probably twice of the true number for whatever reason.  I just cannot
believe that 2 out of 3 users thought the app was bad enough where
even the free version was not worth keeping, but do not reflect this
in their rating. While, obviously, I am a bit biased, I still think
the app is extremely good and does exactly what it promises in its
description.

If you are curious about my app, I'd be happy to tell you its name in
a private e-mail, as I don't want to use this forum as marketing tool.

 I did some checks on our stats and I tend to admit there's something
 wrong with that counter. I see downloads increasing on regular

 comments nor anything that would indicate app failures that could
 lead to mass uninstall.

[android-developers] Re: Sharing data between (tab) activities

[Zsolt Vasvari]

The best way to share data between tabs is to NOT use activities.  I
am not sure what the API people were on (but I want some of it) when
they thought tabbed activities should make it into the final API.

[android-developers] Re: Best way to swap activities

[Zsolt Vasvari]

I think the built-in activity stack and flags are quite good for
simple app logic, but if you have a complicated app, I'd suggest just
use startActivity() and finish() on all your activities and manage the
app flow yourself.  This is what I do and it gives you more control
over what's going on and the user won't get stuck in back-button
hell where, if you have your app coded incorrectly, they have to
press the back button multiple times to exit the app.  The drawback of
managing your own flow is that if you have activities that are
reachable in different ways, you will have to extra complexity of
having to pass in some kind of next activity flag via the intent
extras.

 FLAG_ACTIVITY_NO_HISTORY doesn't do what I want since I want to be

 Before I posted I tried the finish and it wasn't working quite right.
 After thinking about it a bit more, I released that my problem was
 that the activity I was calling finish on was a Tab Content (not the
 tab activity) which was causing some issues. Switching it around to
 call finish on the TabActivity seems to make everything work
 correctly.

Writing to the sdcard or sdcard-like internal storage is possible for

[android-developers] Re: Strange Issue with Return String from Web Service

[Bob Kerns]

In addition to referring you to the thread Ed just referred you to,
I'll specifically highlight:

toString() does not do what you think it does. Yes, it returns a
string. No, it does not extract some string (just which string,
anyway???) from the response.

SOAP responses are complex XML structures. You are going to need to
study the KSOAP2 API, and the web service in question, and figure out
how you will obtain the specific information from the response that
represents 'hazards'.

It's not terribly difficult, but you're asking for it to magically
guess which string out of possibly many. And you're using
Object.toString() to do it.

On Aug 13, 9:39 am, Tommy droi...@gmail.com wrote:
 Hi everyone,

   I have a strange issue. I am using KSOAP2 to create a soap request
 to a .net webservice. I do this in a few other places and everything
 works fine.

 The webservice basically queries a data base and takes the values from
 the data reader and creates a string. This string is then returned.
 When I run the webservice on my local machine(Without using android)
 it works fine. When I run it from the webserver (still not android) it
 works fine. When I call it from my phone however the line:

 String hazards = (String)envelope.getResponse().toString(); //Get
 response from .net Web service

 Simply is filled with anyType{}.

 Now if I go to the webservice and I manually type in the contents from
 the database to represent what the string concatenation should be it
 works perfectly. The line:

 String hazards = (String)envelope.getResponse().toString(); //Get
 response from .net Web service

 Now returns the string value i need.

 Does anyone have any idea why this is happening or know a better place
 to ask this question?

 As always thanks for your time and help

[android-developers] Alarm manager for multiple pending intent are not working.

[nomi]

Hi all,

In my application i have created pending intent which calls another
activity (after 20mins of alarm off) with the help of alarm manger. It
should happen each time for each new pending intent or when I call
that activity.
But when i create one pending intent and after few mins again create
new pending intent ,then the last one overlap the other previous
pending intents and start specified activity only for ones for the
last pending intent.

I want  that each time i create any pending intent it should start
specified activity after 20 mins of it's alarm off time.How it can be
done ?
here is my code:--


Intent intent = new Intent(getApplicationContext(),AlarmCall.class);

intent.putExtra(PolicyNo3,policyNo2);

intent.putExtra(BarcodeNo,barcode_no);

Constants.pendingResultList.put(policyNo2, barcode_no);

System.out.println(Constants.pendingResultList.containsKey(policyNo2));

PendingIntent pendingIntent =
PendingIntent.getBroadcast(getApplicationContext(),
0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = 
(AlarmManager)
getSystemService(ALARM_SERVICE);

long timedely = System.currentTimeMillis() + 
(20*60*1000);

alarmManager.set(AlarmManager.RTC_WAKEUP,timedely,
pendingIntent);









// Below is the code of ALarmCall.class






manger = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
 Notification notification = new
Notification(R.drawable.icon,Please upload
result,System.currentTimeMillis());
 Intent startActivity1 = new Intent();
startActivity1.setClass(context, UploadTest.class);
startActivity1.setAction(UploadTest.class.getName());
startActivity1.putExtra( PolicyNo4,policyNo3);
startActivity1.putExtra(BarcodeNo1,barcodeNo);
startActivity1.addFlags(

 PendingIntent contentIntent = 
PendingIntent.getActivity(context,

Exactly. I don't think that Oracle made such an obvious mistake, even

to Google with the trial thing. This only consolidates the idea that
Oracle doesn't want to shut down Android, but come to a deal (maybe
I'm wrong, but note that even though Oracle officially asked to
withdraw and destroy Android, they didn't ask for a temporary
suspension of Android activities until the trial is finished). If the
deal is only money, it won't affect us in any way. If the deal is also
about changes in the way Android is, it will affect us. I think there
are both positive and negative outcomes - but until they come to a
deal, we really can't know.

and for this I think Memory card is not safe place, because it may

him to store information on server. Please correct me if I am wrong in
the point- we can't create file or database outside the application.

[android-developers] Is there any way to look for an image using the path? MediaStore.Images.Thumbnails (Android)

[jaaaelpumuki]

Hi, I'm using MediaStore.Images.Thumbnails in order to show the images
the user have. But i'm not able to get an image through its path. Is
there any way to look for an image using the path?

String [] proj={MediaStore.Images.Thumbnails._ID,
MediaStore.Images.Thumbnails.IMAGE_ID, MediaStore.Images.Media.DATA};
String selection = MediaStore.Images.Media.DATA +  like '%path%'; //
this doesn't work
cursor =
managedQuery( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
proj, // Which columns to return selection, // WHERE clause;
null,
null); // Order-by clause

If you look into the SettingsProvider class, then you can see that
this is done using

SecureRandom random = SecureRandom.getInstance(SHA1PRNG);

When the persistent system property ro.serialno is set, then this
value
will be used to  reseeds this random object.

Later comes a random.nextLong transformed to a Hex-String.

Interessting might be this part of the javadoc:

the system will determine if there is an implementation of the
algorithm requested available in the environment

Maybe their is a problem with this SHA1PRNG algorithm ?

Try to set ro.serialno  with setprop ..

Good luck !

[android-developers] C2DM Tied to Market? (e.g. will it work on non-official devices)

[Andy Savage]

Hi everyone,

Quick question.

Just wondering if Cloud to Device Messaging (C2DM) is available for devices
that use Android 2.2 but don't have the Android Market installed (because
they are not an official device).

Is this service tied to the Market?

Kind regards,

[android-developers] ListView paint issue in landscape mode.Width remains as in Portrait mode

[Alok Kulkarni]

Hi,
I am having a listview in my App which shows perfectly in Portrait mode.But
when i change orientation to landscape , sometimes the width remains as that
of Portrait mode.Even the scrollbar for the list comes at the center and
remaining part of the screen remains balcked out.This happens only with the
list view.Other views show perfectly.I have designed the layouts such that
the Portrait layouts look feel proportionate in landscape mode . I want to
avoid restarting the activity so i have not put the layouts in the landscape
folder.
I tried invalidating the listview in onConfigurationChanged() but of no use.
When i navigate in the list in landscape mode , the width automatically gets
adjusted.Any help in this regard will be of great use :)
Thanks,
Alok.

Re: [android-developers] Alarm manager for multiple pending intent are not working.

[Kostya Vasilyev]

 Setting an alarm cancels any previous alarms that have the same intent 
as the new one.


In your code, the old and new intents only differ by their extras, which 
are not considered (I believe).


What you could do is calculate the next point in time when an alarm is 
needed, set one alarm, and when it goes off, figure out which of the 
possible actions you need to perform.

Hi all,

In my application i have created pending intent which calls another
activity (after 20mins of alarm off) with the help of alarm manger. It
should happen each time for each new pending intent or when I call
that activity.
But when i create one pending intent and after few mins again create
new pending intent ,then the last one overlap the other previous
pending intents and start specified activity only for ones for the
last pending intent.

I want  that each time i create any pending intent it should start
specified activity after 20 mins of it's alarm off time.How it can be
done ?
here is my code:--


Intent intent = new Intent(getApplicationContext(),AlarmCall.class);

intent.putExtra(PolicyNo3,policyNo2);

intent.putExtra(BarcodeNo,barcode_no);

Constants.pendingResultList.put(policyNo2, barcode_no);

System.out.println(Constants.pendingResultList.containsKey(policyNo2));

PendingIntent pendingIntent =
PendingIntent.getBroadcast(getApplicationContext(),
0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = 
(AlarmManager)
getSystemService(ALARM_SERVICE);

long timedely = System.currentTimeMillis() + 
(20*60*1000);

alarmManager.set(AlarmManager.RTC_WAKEUP,timedely,
pendingIntent);









// Below is the code of ALarmCall.class






manger = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
 Notification notification = new
Notification(R.drawable.icon,Please upload

startActivity1.putExtra(BarcodeNo1,barcodeNo);

[android-developers] Re: Disappearing Alarms

[Pent]

 I have seen this on a number of devices if the phone is idle for a
 long time or if the display gets shut off manually. My app has
 ~100,000 users so I am quite sure I am not imagining it. My phones (N1
 and Galaxy) are not affected, but I get a lot of these reports from
 Droid users.

 Here's a simple test I would recommend:
 - tell your users to set the stock alarm. If you experience the same
 situation that I talk about, you will find the stock alarm fails, too.
 - tell your users to keep the phone plugged in. Your alarm will no
 longer fail.

 If these tests show my experience is relevant to your problem, I have
 a number of suggestions what else you can do.

Thanks for the info, will make inquiries.

http://code.google.com/p/android/issues/detail?id=7479As mentioned in the

gets unlocked it starts in the other mode hence a new activity is getting
created each time.

[android-developers] Re: Is anyone's active install % dropping like a rock lately?

[String]

I grew distrustful of the Console download figures in mid June and
began keeping track of all the numbers I could lay my hands on for my
apps. I was sort of collecting data to get a handle on what was wrong,
so that I could share it with other devs, when Google admitted they
had a problem - and corrected it (http://tinyurl.com/3xvj76o).

Since then, my total downloads and my Checkout payments have tracked
each other quite well, within about +/-5%. It's hard to be more
precise than that because, although the Console data is clearly
delayed, it's not clear by how much. But generally, they are pretty
close.

As for active percentage (the original topic of this thread), I've
come to believe that it's ALWAYS going to trend downward over time.
This is natural, as very few users keep apps, even paid ones,
installed forever. So attrition will always take its toll, and the
active user count - as a percentage of users who have EVER installed
your app - will always tend downward. As a result, the active % is
almost more of just a measure of how long your app has been released
than it is a measure of user satisfaction.

Supporting this thesis, here is my own data. I have 4 paid apps in the
Market, all in the $1-$2 range, all with 4.5* ratings. Here are their
active percentages, along with their original release dates:
55%: Aug 2009
70%: Feb 2010
70%: Mar 2010
79%: May 2010

Bottom line: don't worry about active percentage.

String

On Aug 16, 8:05 am, Zsolt Vasvari zvasv...@gmail.com wrote:
 I noticed the same thing.  Let me share a few stats for my app.

 The active rate from 40% to a 32%, but at the same time the overall
 rating has gone up a little bit, from about 4.22 to 4.33 as shown by
 AppBrain, so the overall rating is more 5 stars than 4.

 There isn't a single bad comment posted, literally everything is = 4
 stars since the early problematic days when I had a few FC bugs.  I
 get one rating for about 1 in 36 downloads and one comment in probably
 1 in 100.

 So it's either that 2 out of 3 people download my app and they don't
 like it and uninstall it, but don't bother giving it a low rating or
 comment, or that the install count is shown to be too high.

 As I have mentioned it previously, as I am having a problem with my
 app buried so deep into cr*p on the Android Market, that I actually
 very surprised that as many people would discover it daily as they
 do.  My app is doing much better on AppBrain placement-wise and it's
 actually one of the top apps in its category and would most likely be
 evaluated by people who are doing comparission shopping in this
 category.

 My gut feeling is that the download numbers on the Android Market are
 probably twice of the true number for whatever reason.  I just cannot
 believe that 2 out of 3 users thought the app was bad enough where
 even the free version was not worth keeping, but do not reflect this
 in their rating. While, obviously, I am a bit biased, I still think
 the app is extremely good and does exactly what it promises in its
 description.

 If you are curious about my app, I'd be happy to tell you its name in
 a private e-mail, as I don't want to use this forum as marketing tool.

[android-developers] Re: Alarm manager for multiple pending intent are not working.

[Paul Turchenko]

PendingIntent.FLAG* should help you.

On Aug 16, 12:44 pm, Kostya Vasilyev kmans...@gmail.com wrote:
   Setting an alarm cancels any previous alarms that have the same intent
 as the new one.

 In your code, the old and new intents only differ by their extras, which
 are not considered (I believe).

 What you could do is calculate the next point in time when an alarm is
 needed, set one alarm, and when it goes off, figure out which of the
 possible actions you need to perform.

  Hi all,

  In my application i have created pending intent which calls another
  activity (after 20mins of alarm off) with the help of alarm manger. It
  should happen each time for each new pending intent or when I call
  that activity.
  But when i create one pending intent and after few mins again create
  new pending intent ,then the last one overlap the other previous
  pending intents and start specified activity only for ones for the
  last pending intent.

  I want  that each time i create any pending intent it should start
  specified activity after 20 mins of it's alarm off time.How it can be
  done ?
  here is my code:--

  Intent intent = new Intent(getApplicationContext(),AlarmCall.class);

                                     intent.putExtra(PolicyNo3,policyNo2);

  Constants.pendingResultList.put(policyNo2, barcode_no);

  System.out.println(Constants.pendingResultList.containsKey(policyNo2));

                                     PendingIntent pendingIntent =
  PendingIntent.getBroadcast(getApplicationContext(),
  0,intent,PendingIntent.FLAG_UPDATE_CURRENT);
                                     AlarmManager alarmManager = 
  (AlarmManager)
  getSystemService(ALARM_SERVICE);

                             long timedely = System.currentTimeMillis() + 
  (20*60*1000);

  alarmManager.set(AlarmManager.RTC_WAKEUP,timedely,
                                         pendingIntent);

  // Below is the code of ALarmCall.class

  manger = (NotificationManager)
  context.getSystemService(Context.NOTIFICATION_SERVICE);
              Notification notification = new
  Notification(R.drawable.icon,Please upload
  result,System.currentTimeMillis());
              Intent startActivity1 = new Intent();
                     startActivity1.setClass(context, UploadTest.class);
                     startActivity1.setAction(UploadTest.class.getName());
                     startActivity1.putExtra( PolicyNo4,policyNo3);
                     startActivity1.putExtra(BarcodeNo1,barcodeNo);

                     Intent.FLAG_ACTIVITY_NEW_TASK

              PendingIntent contentIntent = PendingIntent.getActivity(context,

[android-developers] Dealing with password change on the server in a SyncAdapter

[Kwisatz]

Hope you can help me with this, because I've tried EVERYTHING and the
example in the Google sample code doesn't seem to work.

Scenario:
- An account is created in the AccountManager with a valid username
and password.
- A SyncAdapter is present to deal with server syncs, and successfully
authenticates in the server using the stored credentials through the
AccountManager.
- The user decides to change the password on the server. So, the
password in the Android AccountManager becomes invalid, and we have to
request the user a new password when a synchronization fails with a
401 HTTP error from the server.

According to Google, this can be done. Here's what I understood by
reading the API docs:

1. In the SyncAdapter that extends AbstractThreadedSyncAdapter, when
we request the AuthToken, we set the notifyAuthFailure to false:

String authtoken = accountManager.blockingGetAuthToken(account,
Constants.AUTHTOKEN_TYPE, false);

2. In the Authenticator that extends AbstractAccountAuthenticator, we
return the following in the getAuthToken method:

final Intent intent = new Intent(context,
AuthenticatorActivity.class);
intent.putExtra(AuthenticatorActivity.PARAM_USERNAME, account.name);
intent.putExtra(AuthenticatorActivity.PARAM_AUTHTOKEN_TYPE,
authTokenType);
intent.putExtra(AccountManager.KEY_ACCOUNT_AUTHENTICATOR_RESPONSE,
response);
final Bundle bundle = new Bundle();
bundle.putParcelable(AccountManager.KEY_INTENT, intent);
return bundle;

This should call the AuthenticatorActivity defined in the Intent, but
it doesn't. It just invokes the getAuthToken method again.

I've tried calling directly from the from the SyncAdapter the methods
confirmCredentials and updateCredentials, but they will never launch
the AuthenticatorActivity.

What I'm I doing wrong?!
How can we request the Authenticator to show an Activity to ask for a
new password?

In all examples that I've seen, they all assume that the credentials,
once they are valid, then they will never change.

 If you install if from a non-market source, the permissions are always
 pretty much the worst case scenario. I guess this is due to the
 installer not knowing what the permissions really are. Once you upload
 the app to the market, the permissions should read what they really
 are.

[android-developers] Crop an image

[Nea]

I have an imageview which has a photo taken with the camera as its
background and a frame as it's foreground (src). In that way the photo
is positioned behind the frame so the photo get's a nice border.

The imageview is a square (265x265dip). Now the problem is that photos
taken are rectangular and thuse they are squeezed into the imageview
making them look akward.

So how can I crop the bitmap of the photo so it is fitted as a square
so I can then put it as a background for the imageview?

Re: [android-developers] Re: How to write ContentProvider for content not stored in a file nor DB?

[Kostya Vasilyev]

 Sereja  Pavel,

It should be just a little bit more involved than writing a SQL-based one.

For structured data, you'd need to create your own Cursor subclass, and 
return it from the provider's query method. If query results are small 
enough to fit in RAM, then it's easiest to use MatrixCursor.


For stream-based data, ContentResolver.openStream seems to eventually 
call ContentProvidersubclass.openFile. This method returns a special 
helper class, ParcelFileDescriptor, which allows file descriptors to be 
passed across process boundaries.

[android-developers] XML parsing slow ... cache!

[Davide]

Hi,

I have seen that xml parsing is very slow. Using sax would be better,
but benchmark show that sax work only 30%
faster as dom. Is right? Is faster if I construct a DOM using sax?

To reduce time i like to cache xml file. Caching it as xml is not a
good idea because the parsing time is there again
the secondo time.

Should I use sqllite? Is faster? Is an idea to use an
ObjectOutputStream? Can I put in asset a file maked by
ObjectOutputStream
or the serialized objects can be different in different mobile hardware?

Davide, have you run some precise test so you are sure you've spotted
the bottleneck? Just to be sure that it's really XML the problem (and
not I/O). JSON could be an alternative. I've run some tests with
serialization and theoretically works (I exchanged objects between
Android and a JavaSE app), but it's somewhat brittle. Also, I'm not
sure it's fast because introspection is not fast on Android (it might
be different with 2.2). Also consider JDom / Jaxen as an alternate XML
parser, might be worth while compare their performance.

[android-developers] Re: XML parsing slow ... cache!

[Mark Gjøl]

On my first implementation I used a DOM-parser for my XML (Flickr, 500

SAX-parser, and it's less than a second. The speedup was tremendous,
so it can definitely be worth your time, at least to test the
difference!

Probably, assuming you can detect when a scroll happens, which I'm sure you

past the threshhold you want to allow, get the MapController() and reset it
to where your limit is.

I'll leave the implementation details to the reader =)

[android-developers] Re: How do I convert float to 2 decimal places?

[Robert Nekic]

Yeah, I use the NumberFormat:

NumberFormat numberFormat = DecimalFormat.getInstance();
numberFormat.setMaximumFractionDigits(2);
String formattedText = numberFormat.format(yourFloat);

Re: [android-developers] Re: position add remove imageview

[Kostya Vasilyev]

 Nikhil,

The default position of child views with RelativeLayout is indeed at 0,0.

You need to do something to position the child view.

Use RelativeLayout.LayoutParams and and specify some values.

You can use layoutParams.setMargins (correspond to XML 
layout_marginLeft, layout_marginTop, etc.)


Or you can use layoutParams.addRule (correspond to XML layout_below, etc.)

[android-developers] Re: Compiling and obfuscating by command line...

[sblantipodi]

I have created the ant build as suggested by you but I can't figure it
out.
Unfortunantly I haven't got a day for this... :(
Can't understand how it is possible that there is no guide on how to
do that in a fast way.

 Well, I suggested a better approach to setting up your ant script, and

 I've extracted the relevant sections from your reply below, in case
 you missed it.

 You haven't told us of any problem with ProGuard -- the last thing you
 reported was a problem getting set up to build with the SDK, long
 before getting to ProGuard. If you follow my recommendation, you can
 be up and running with that in a few minutes, and then maybe if you
 have problems with ProGuard, we can help you with those.

Anyway -- it looks to me like your problems stem from not starting
from a working ant build and then adding obfuscation.

If you follow the documented approach for creating a new ant build
project, and then move your code into it, you should have a working
build virtually out-of-the-box. You can then turn that into a NetBeans
project or Eclipse project without much trouble, and get the benefits
of both worlds. Probably even all three is doable!

Then, once you have that working ant build, extend it with an
obfuscation step. I haven't done that yet -- but having seen how the
base ant build is generated, I absolutely would not try it without
first having a solid ant build in place. Then you would not be
experiencing errors like tasks not defined or missing targets.

The negatives are real, and one is that it will take you some time to
set it up and get right, and a lot of testing to make sure it's
right.  But I think it will go faster if you start with a blank ant-
build project, get that solid, and then add obfuscation.

[android-developers] Re: XML parsing slow ... cache!

[DanH]

Comparing DOM and SAX is like comparing apples and bullfrogs.  They do
two largely different things.  DOM reads in an entire XML document and
stores it as Java objects so that you can quickly reference parts of
it without knowing (or at least having to specify) in advance what
parts you're interested in.  SAX (rapidly) parses an XML file but
leaves it up to you to know (and write code for) which parts to save
as it speeds by.

A new, middle of the road technology is pull parsing, which uses a
SAX-like scanner but lets you specify in advance which elements you
want saved.

Another option is to use a lighter weight markup language.  JSON is
much more compact, parses much faster, and is generally easier to deal
with.

If you want to cache an XML file it would make more sense to cache
the parsed information vs the original file, if parsing speed is
already an issue.  There are a dozen different ways to cache the
parsed information, depending on its size and structure.

[android-developers] webview issues with listview.

[charles berman]

Im having some problems with my application and while i think i know what is
causing it, im not completely sure how to fix it.

my application searches a website and adds entries to a database and then
displays the users in a listview with a cursoradaptor.

when the entries are first displayed, i get an sql finalize error. I thought
maybe i had something to do with my cursoradaptor but it never shows its
head until after i exit my newview or bind view and even then, it is only
displayed once.

my other idea was that maybe it has something to do with the fact that im
using a webview. I used the webview because allthough it seems quicker to
load the profile images to the listview. I do have issues because the images
arent all loaded at once, and once i scroll down, the new images are
displayed and some of the first images until the real image for the user is
downloaded ( i dont really know how to describe that correctly)

Re: [android-developers] Re: XML parsing slow ... cache!

[Kostya Vasilyev]

 David,

XML parsing options available in Android were discussed here within the 
last month.


I recall that Dianne Hackborn posted some interesting performance 
comparisons.


Try finding that thread, I think it should be quite interesting w.r.t. 
to your question.


Android also includes the ability to parse XML precompiled into some 
sort of binary format, this is faster than parsing text. This is how 
layouts and other platform-specific resources are packaged in the .apk. 
Perhaps there is a way to use binary XML for your own files as well.


You can put any file you want into the asset folder, and have access to 
it at runtime. There is no reason it can't be a file with persisted objects.


So there are many good ways to skin this particular cat.

 I suspect the actual error is thrown by Google Checkout, since they are

Probably. Google Checkout was clearly not designed to work for Android and
is a tacked on hack. It is what it is though.

[android-developers] Re: Is anyone's active install % dropping like a rock lately?

[Doug]

 So attrition will always take its toll, and the
 active user count - as a percentage of users who have EVER installed
 your app - will always tend downward. As a result, the active % is
 almost more of just a measure of how long your app has been released
 than it is a measure of user satisfaction.

Well, that's not been my experience, as my % grew over time and peaked
at 70% after about 10 months on the market.  It wasn't until the last
few months that it dropped rapidly to 54%.

Also, if attrition is going to be a known phenomenon (as I originally
suggested with the idea that old phones get decommissioned over time),
why wouldn't the stats take that into account?  Certainly Google can
tell the difference between an explicit uninstall and a device that's
been trashed (hasn't phoned home in a long time).

I'm not so much concerned about the number being wrong as the idea
that the number has something to do with the rankings on the market.
If active install % is important for rankings, and that number is
destined to drop over time, tenured apps are forced to fight gravity
increasingly over time, even if they continue to improve over that
same time.

 Bottom line: don't worry about active percentage.

Well, I'm not sure about this statement because if active install % is
an (important) factor in app rankings, then I should very much be
concerned about that number.  Rankings are everything as far as
visibility is concerned.  It's all about getting as high as possible
into the rankings if you want your app to be noticed and sell.

If Google just came clean on the algorithm that is used to calculate
rankings, then we'd know for sure if there's anything to worry about.

It's extremely unlikely they would do that.

All we can do is try to encourage them to use a fair/accurate ranking
algorithm.

For example, there's a world of difference between a high quality niche app
(high rating, low active install rate) and a lower quality general-purpose
app (lower rating, high active install rate).

[android-developers] Droid X background or font color issue?

[andrew android]

Hi !

I just got a message from a user of one of my apps that upgraded and
reinstalled onto a Droid X and she says that now the dropdowns
spinners) are defaulting to white font on white background.

Do any of you know of a difference in font color defaults on the Droid
X?

Any suggestions or ideas?

Thanks!

[android-developers] Re: Is anyone's active install % dropping like a rock lately?

[Maps.Huge.Info (Maps API Guru)]

I've seen a drop in active install percentage as well. My most popular
app, Radar Now! was at 67% for many months then a few weeks ago it
started to drop and now is sitting at 65%. While that may not seem
like a lot, the app has over 700,000 downloads, so it is quite a few.
I had attributed it to Droids filling up their app space and looking
for little used apps to uninstall. On average, 375,000 devices use the
app in a 30 day period so the install percentage may be correct.

It could be that Google has adjusted the active installs to take into
account devices that have been removed from service. It could be as
simple as counting apps per Google account and combined duplicates.
That would make a lot of sense and also show a more accurate figure in
the console.

I would also guess that Google is getting better at figuring things
out with the market and a result of that is a change in statistics.

The bottom line is that it seems to be happening to everyone, so as
the saying goes, a falling tide lowers all boats.

[android-developers] Problem item in AlertDialog

[FlorentCode]

Hi all,

Thanks to help people!

I use an AlertDialog with list (singlechoice-radioButtons). When I
choose an item from the list, a toast come and I do a setText of the
item on a textView.
Everything works when I declare my items like this:
--
 
((ImageButton)findViewById(R.id.pickPays)).setOnClickListener(new
OnClickListener(){

public void onClick(View v) {

final CharSequence[] items = {United States,
France, Sweden};
AlertDialog.Builder builder = new
AlertDialog.Builder(Postit.this);
builder.setTitle(Selectionne ton pays);
builder.setSingleChoiceItems(items, -1, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
item) {
dialog.cancel();
Toast.makeText(getApplicationContext(),
items[item] , Toast.LENGTH_LONG).show();
((TextView)
findViewById(R.id.paysDisplay)).setText(items[item]);
}
});
AlertDialog alert = builder.create();
alert.show();

}
});




But I want declare my items in a array.xml
So I created an array.xml 'pays.xml' and I changed my code like this.
The problem is: the application crash when I select an item so when
the toast and the setText are called.
Do you have any ideas how can I declare my item in the toast and the
setText?



 
((ImageButton)findViewById(R.id.pickPays)).setOnClickListener(new
OnClickListener(){

public void onClick(View v) {

AlertDialog.Builder builder = new
AlertDialog.Builder(Postit.this);
builder.setTitle(Selectionne ton pays);
builder.setSingleChoiceItems(R.array.pays, -1, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
item) {
dialog.cancel();
Toast.makeText(getApplicationContext(), item ,
Toast.LENGTH_LONG).show();
((TextView)
findViewById(R.id.paysDisplay)).setText(item);
}
});
AlertDialog alert = builder.create();
alert.show();

}
});



Thanks in advance,

Florent

[android-developers] Problem with Saxparser and malformed XML

[MarkG123]

Hi, I am using a saxparser to read RSS XML from the web and populate
listviews. Everything works fine until I come across malformed XML,
usually encoding related, and my reader falls over.

I have changed it so that it gets as many items parsed and populated
before falling over (by default if it finds a malformed XML, then it
will give up and return an empty collection). The problem is, the next
time I try and view that feed (or any other feed), it still has the
contents after the malformed bit hanging around. For example, the
first time it now shows all the items upto the malformed item, if I
refresh, it will only show items after, refresh again, it will show
items upto and so forth.

The weird thing is, I create a new instances of everything every time.
So I don't understand why stuff is handing around.. It's like there is
some read pointer, or connection that needs to be closed and reset,
but I can't for the life of me work out what or where!

Any help would be gratefully appreciated. Thanks.

My GetFeed method:

 private RSSFeed getFeed(String urlToRssFeed)
   {
   SAXParserFactory factory;
   SAXParser parser;
   XMLReader xmlreader;
   URL url;
   InputSource is;
  try
  {
 url = new URL(urlToRssFeed);
 factory = SAXParserFactory.newInstance();
 factory.setValidating(false);
 parser = factory.newSAXParser();
 xmlreader = parser.getXMLReader();

 xmlreader.setContentHandler(m_FeedHandler);
 is = new InputSource(url.openStream());
 xmlreader.parse(is);
 m_ErrorCode = NOERROR;
  }
  catch (SAXParseException e)
  {
 e.printStackTrace();
 m_ErrorCode = XMLFORMAT;
  }
  catch (Exception e)
  {
 e.printStackTrace();
 m_ErrorCode = CONNECTION;
  }
  finally
  {
  is = null;
  url = null;
  parser = null;
  factory = null;
  return m_FeedHandler.getFeed();  //May be complete, partial
or empty.
  }
   }

[android-developers] Re: When are the overlays drawn on the map?

[cnbishop]

hi, i was wondering if you could talk a bit about how you were able to
get the overlays to update dynamically? i am trying to do something
similar where i remove any existing overlays, and add a new overlay
with a new geopoint every couple of seconds.   in a nutshell, i am
basically getting the user's gps location; adding a random geopoint in
a different overlay and calculating the directions from the random
geopoint to the user's gps point.  from there, i am trying to get the
random geopoint to move (basically remove an overlay and add a new
one with the next point in the mPoints of the directions).  everything
is working up until adding the moving points.   is this even
possible?

here is where i set the overlays up:

//mapView.invalidate();
// 1. get enemy's last known location
if(started == false){
mapView.getOverlays();
mapOverlays.clear();
enemyOverlay = new GameOverlay(drawableEnemy, null);
enemypoint = new GeoPoint(37779350, -122419250); // 
need to set
this to random initially
OverlayItem enemyoverlayitem = new 
OverlayItem(enemypoint, ,
);

enemyOverlay.addOverlay(enemyoverlayitem);
mapOverlays.add(enemyOverlay);
}


// 2. get user's current location
double fromLat = 37.779350, fromLon = -122.419250, toLat =
latPoint, toLon = lngPoint;
//point = new GeoPoint(37779350, -122419250); // need to set
this to gps
point = new GeoPoint((int) (latPoint * 1E6), (int)(lngPoint *
1E6));
userOverlay = new GameOverlay(drawable, null);
OverlayItem useroverlayitem = new OverlayItem(point, , );
userOverlay.addOverlay(useroverlayitem);
mapOverlays.add(userOverlay);
MapController mc = mapView.getController();
mc.animateTo(point);
mc.setZoom(1);
//mapView.setSatellite(true);
//mapView.invalidate();

// 3. get directions from enemy to user
String url = RoadProvider.getUrl(fromLat, fromLon, toLat,
toLon);
InputStream is = getConnection(url);
mRoad = RoadProvider.getRoute(is);


// 4. move enemy
mapView.getOverlays();
mapOverlays.clear();
if(started == false){
newEnemyPoint = moveEnemy(point, enemypoint, mRoad);
}


enemyOverlay = new GameOverlay(drawableEnemy, null);

OverlayItem enemyoverlayitem = new OverlayItem(newEnemyPoint,
, );
enemyOverlay.addOverlay(enemyoverlayitem);
mapOverlays.add(enemyOverlay);


enemyOverlays = mapView.getOverlays();
enemyOverlays.clear();
GeoPoint currentPoint = null;
for (int i = 0; i  road.mRoute.length; i++) {

currentPoint = new GeoPoint((int) (road.mRoute[i][1] *
100), (int) (road.mRoute[i][0] * 100));


moveEnemy(currentPoint, i);
}

and here is my move function:

public GeoPoint moveEnemy(GeoPoint userPoint, GeoPoint enemyPoint,
Road mRoad) {

float userLatitude = userPoint.getLatitudeE6();
float userLongitude = userPoint.getLongitudeE6();

float enemyLatitude = enemyPoint.getLatitudeE6();
float enemyLongitude = enemyPoint.getLongitudeE6();



enemyOverlays = mapView.getOverlays();

for (i = i+1; i  mRoad.mRoute.length; i++) {


if(userLatitude != enemyLatitude  userLongitude !=
enemyLongitude){


return newEnemyPoint = new GeoPoint((int)
(mRoad.mRoute[i][1] * 100), (int) (mRoad.mRoute[i][0] * 100));
} else {
System.out.println(hi: you lost);
}

}
started=true;

return newEnemyPoint;

}

[android-developers] Adapter drop down clipped on floating window

[Christopher Fraser]

Hello,

I'm having a problem with floating windows. My activity has an
AutoCompleteTextView text in a floating window positioned at the top
of the display. If enough text is entered to make the drop down appear
it will be initially clipped to the bottom edge of the window. If you
click on the drop down it appears unclipped.

I've stripped my activity down to a test program and put a copy here:

http://www.invisibility.org.uk/adaptertest.tgz

In summary, the main activity just inflates a view and positions it at
the top of the display:

public class AdapterTest extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

getWindow().setGravity(Gravity.TOP|
Gravity.FILL_HORIZONTAL);
getWindow().setLayout(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT);

LayoutInflater inflater = getLayoutInflater();
View v = inflater.inflate(R.layout.main, null);
setContentView(v);

ArrayAdapterString adapter = new ArrayAdapterString
(
this,
android.R.layout.simple_dropdown_item_1line,
new String[] { aaa0, aaa1, aaa2, aaa3 }
);
AutoCompleteTextView textView = (AutoCompleteTextView)
findViewById(R.id.textView);
textView.setAdapter(adapter);
}
}

The activity is set to use the following style in the manifest:

?xml version=1.0 encoding=utf-8?
resources
  style name=Theme.Floating parent=@android:style/Theme
item name=android:windowIsFloatingtrue/item
item name=android:windowBackground@android:color/black/item
  /style
/resources

Just in case they layout is as follows:

?xml version=1.0 encoding=utf-8?
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:orientation=horizontal
android:layout_width=fill_parent
android:layout_height=wrap_content
android:paddingLeft=10dip
android:paddingRight=10dip
android:paddingTop=10dip
android:paddingBottom=10dip

AutoCompleteTextView
android:layout_width=fill_parent
android:layout_height=wrap_content
android:id=@+id/textView
/
/LinearLayout

Any ideas?

[android-developers] Problems drawing a translucent Path on a SurfaceView

[Niklas]

Hi, I'm having some trouble with the following code:

paint.setColor(Color.WHITE);
paint.setStyle(Paint.Style.STROKE);
paint.setAlpha(100);
paint.setStrokeWidth(12);
canvas.drawPath(path, paint);

It seems that the alpha setting is ignored, as the Path will be drawn
fully opaque. If I call drawLine() or drawLines() using the exact same
Paint object, the translucency is displayed fine. I looked through the
Javadocs on Path, Canvas and Paint (And searched this group) but
couldn't find any explanation.

Any ideas of what I might be doing wrong? Thanks!

[android-developers] Emulator shortcomings regarding the touchscreen interaction

[Mihael]

Obviously it is not the same to test the application in the emulator
with the mouse or even touchscreen opposite to the real device. My
question is, how would you improve emulator to better reflect testing
experience from real device? Which are the features that are missing?

First of all, there is issue of multitouch emulation (http://
code.google.com/p/android/issues/detail?id=5977).
