I believe being able to provide refunds is important. When you go to a 
real-world store, you can touch, look at, try on items before paying, 
and yet stores typically let you bring purchases back and get a refund. 
This is so that the customer knows that if something - unexpected and 
unforeseen - goes wrong, he can get his money back. That's psychology, 
not technology.


Secondly, as a user, I prefer the situation where the pro version offers 
additional features compared to the lite version, and not where the lite 
version has the same features, and is deliberately made annoying in some 
way (nag screens, start-up delays, etc.)  The user hopefully goes to buy 
the pro version to get those extra features, hoping that they work as 
advertised, but he has no ways to verify that before paying.


Third, putting info about refunds in the application's UI would directly 
contradict what the user sees in the purchase window. And since the 
former is part of the application, and the latter comes from Google, 
which one do you think he's going to believe?


Finally, providing information to the user about refunds in one place, 
the purchase window, would seem to me like valuable thing. Probably not 
too difficult to provide a boolean flag in the API so that the purchase 
window can say Refunds for this item are provided by the developer.

I'm just concerned that it might deter purchases for lite to pro
conversions.
 For buying in-game gems or potions it shouldn't really matter,
those are impulse purchases and for smaller amounts too.


Why would it deter payments?

Here's the main value I see in the refund period: there is something 
you are purchasing, that you haven't actually been able yet to even 
try to download and install, so really have no idea what you are 
getting.  Being able to get a refund if it is not what you want, 
buggy, or has other issues is important to have any confidence in 
buying in that situation.


Using in-app purchases within an app is entirely different though. 
 Consider the same situation with a lite vs. pro version: you 
downloaded the app for free, have been using it for however long you 
want (or however long the developer will let you), and have no decided 
it is worth spending $X to purchase it (or unlock a certain feature 
etc).  What benefit does a refund period really give you here?


Or look at this another way: the beauty of using in-app purchases for 
all of this is that *you* are in complete control of the user 
experience through this thing.  All you need to do is get the user to 
download and run your free app, and after that you get to decide 
exactly how you want to interact with the user towards paying for the 
app.  All in-app billing provides is the final point where the user 
has decided yes it is worth the money, I am paying.  So you can do 
all kinds of things:


- Have the full app running as a limited time trial, after which the 
user must purchase to continue using.
- Have the full app running with ads, and the user able to pay to get 
rid of the ads.
- Have limited features available in the free app, with a payment to 
unlock the full features (or even multiple payment options to unlock 
different features).

- Allow the user to try out for-pay features for a limited amount of time.
- Show a nag message every now and then encouraging the user to pay 
for your app to encourage further development.

- And on and on!

And in all of these cases, it is clear that the interactions here are 
directly between you as the app developer and your users, with Market 
now just being the point where the user hands over some cash.

that FileOutputStream only has write methods for byte vectors. Byte
can only be up to 128, and timestamps are bigger numbers than that. I

[android-developers] Re: How to connect mysql with android

2011-02-05 Thread Tim

Android does indeed support direct connectivity to most databases
including MySQL.  Android is fully JDBC compliant and all you need to
do is find and embed the correct JDBC driver inside your Android app.
Most JDBC drivers are covered by GPL.  The remaining problem then is
to encode the necessary database result set logic.  JDBC is totally
secure if sufficient thought is given to database settings and router
filters.  JDBC avoids the need for additional cumbersome layers of
SOAP or REST services.

The above is fine for simple database access, however, you may find
that using a rapid application development tool such as our MobiForms
Developer may be more effective.  MobiForms is particularly designed
for the creation of database orientated mobile apps.  Most programming
is done by drag and drop and by the selection of tables and columns in
a true relational database approach.  MobiForms supports direct access
to a range of industry standard databases such as Oracle, SQL Server
and MySQL.

For disconnected apps or where wireless connectivity can not be
guaranteed the MobiForms Sync Server is available.  This provides
offline bi-directional database buffering and online synchronisation
for true store and forward apps.

Typical apps created using MobiForms include bar coding, field
service, marketing, signature capture, stock control and surveys.
Often these are directly connected to back office systems such as
Microsoft Navision/Dynamics, Oracle Apps and SAP etc.

Re: [android-developers] webview + scrolling

2011-02-05 Thread sagar masuti

Hi Mark,

I have implemented a class named WidgetView.java which extends from
FrameLayout.
This acts as a container for Webview.In my class I handle the touch events
according to my specific requirements.
Now when i remove FrameLayout and use some other layout I am not able to
display any content.
Could you please suggest a way wherein I can display the contents and also
handle the touch events as per my requirements.
Is it possible for me to extend my WidgetView.java class directly from
WebView.java.Any pointers will be highly appreciated.
Thanks in advance.

Regards,
Sagar

Why do you have a FrameLayout?

Why do you have android:orientation=vertical in your FrameLayout,
considering that FrameLayout does not honor that attribute?

I have implemented the WebChromeClient and WidgetViewClient.

That's WebViewClient.

I have
implemented the onTouchEvent and passing the touch events to the
WebView.

That seems unlikely to work well.

The problem i am facing is am not able to scroll inside the webview.
For example, the content is some 5 lines then am able to see only 3
lines and not able to scroll.

The touch events go to Webview, first action_down and then
action_move, am not able to get what wrong am doing??

You are assuming that WebView is like any other widget. It is not. It
is implemented via WebKit, which has its own notions of event handling
that may or may not blend well with your own touch event handling.

What are you trying to achieve by intercepting the touch events?

Since WebView knows how to scroll on its own, I would recommend you
simply get rid of the FrameLayout and your own touch handling, and let
WebView do what it does naturally.

To send a silent report (i.e. something the user isn't aware of) you can use 
the details here:

http://code.google.com/p/acra/wiki/ACRA3HowTo#Can_I_send_reports_for_caught_exceptions_?_or_for_unexpected_appSo
 
in code when you catch an exception you want to log, you simply put in: 
ErrorReporter.getInstance().handleException(caughtException);

If you don't have an exception thrown but you still want to log something 
then I think there is a variant of that method you can call which will 
accept a string instead. I don't have java opened so can't confirm the exact 
method.

[android-developers] Re: URL query string bug in SMS messages

Well that is almost not an option to not use query strings in a SMS.
One work around would be to use a link shortener prior to sending out
the SMS from our SMS gateway. (Given that the link shortening service
does not crawl the site prior to shortening it)
Or to rather make the quer part of the sites subdomain. That being a
tad trickier to handle on the server side.

Either way it feels rather odd that this is not supported on the
Android platform when it is on Symbian, Maemo, iOS and WP7.

Gingerbread is Android 2.3. Honeycomb is Android 3.0.

Alarm manager makes does not care network connection. It fires alarms

Yes, the alarm gets called... it's just my own call which stops it

public static boolean isNetworkAvailable(Context context) {
ConnectivityManager connMgr = (ConnectivityManager)

NetworkInfo info = connMgr.getActiveNetworkInfo();

So this call tells me the network isn't available when the phone's

Re: [android-developers] Re: Scheduling ideas


Neil,

That's pretty much how I test too, except my code lacks a check for 
isConnected, only for null.


This is what I get in my app's log:

NetworkInfo: type: MOBILE[EDGE], state: CONNECTED/CONNECTED, reason: 
apnSwitched, extra: internet.mts.ru, roaming: false, failover: false, 
isAvailable: true


Two ideas:

- Check your phone settings, perhaps yours has some kind of sleep policy 
for mobile data;


- Log the value you get by calling getActiveNetworkInfo into a file, and 
examine later.

Depends on what kind of network connectivity you expect.

In my tests (Moto Milestone), WiFi doesn't get enabled when the phone is
woken by an alarm, but the cellular data connection is available
immediately.

[android-developers] Re: Emulator with disabled camera still has camera?

2011-02-05 Thread blindfold

It looks like the emulator currently only supports one default
hardware configuration for hasSystemFeature()
http://code.google.com/p/android/issues/detail?id=11682 which indeed
is inconvenient for emulating/testing app behavior for different
hardware configurations.

 However when I run the emulator this call still returns true

 Is this a bug in the emulator that I should report or am I missing

You don't read in a byte vector. You read in a string. You convert the

You really need to back off of Android development for a while and learn Java.

Re: [android-developers] Re: How to store a timestamp to the sd card?

The very least you can do is use application-specific storage for your 
timestamp value.


The memory card is accessible and writable by anyone, including other 
applications and the user, and storing the timestamp as text is 
practically begging for someone to mess with it.


I'd suggest you use SharedPreferences:

http://developer.android.com/reference/android/content/SharedPreferences.html

... which can write and read long type values (your timestamp).

Shared prefs are cleared when the app is uninstalled, so doing this and 
installing again will start your trial period again. But without an 
off-phone (server) storage, there is not much you can do anyway.

Not fully agreee. If you do this right way, it will somehow serve the
purpose. Choose path and filename wisely (resist from naming your file
like my_app_name/timestamp.txt). Additionally you may want to write
device ID too to prevent sharing that file. And if you write some
noise (like /dev/random :) around your timestamp data to bload the
file slightly (say 512/1024 bytes) then some 'hackers wannabe' may
stay away. Of course one may put some effort and hide path and
filename in the code so it's not easily spotable by just peeking the
binary. I'd also fake timestamp on the file once created to make it
older that app installation. Or just be creative yourself :)

 I'd suggest you use SharedPreferences:

Uninstalling the app and doing fresh install kills this type of protection so
it's not the solution. SD card file will survive it.

Hi! Thanks for your answer. Unfortunately setting editable=false
does not do the trick. When I'm moving the focus via hard keys from a
normal EditText to the View where I'd like not to have soft keyboard
shown it still stays on the screen.

ps. Sorry I didn't answer earlier, I couldn't find my post for some

  Hi!

  I would like a way to turn off showing the current soft keyboard for

  NOT to be shown.

  The closest things I found

  and

 http://stackoverflow.com/questions/1109022/how-to-close-hide-the-andr...

  These however do not work for me.

  The solution suggested in the latter

  InputMethodManager imm =
  (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
  imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0);

  for example works only after the EditText has been selected by the
  user and is already accepting input and so the soft keyboard is
  already on the screen. I want it never to appear.

  I can try to implicitly set all of the onFocusChangeListener,
  onTouchListener, onClickListener  to do

  public void onSomeActionListener(View v) {

  InputMethodManager imm = (InputMethodManager)

                                  imm.toggleSoftInput(0,0);
                          }

  }

  However, this is really not a nice solution because

  1) the soft keyboard is first called and shown so that it briefly
  flashes on the screen before disappearing

  2) I can't by trial and error try to find all the different ways user
  could cause soft keyboard to be shown and override all corresponding
  methods

  Thanks for your help!

[android-developers] Re: URL query string bug in SMS messages

2011-02-05 Thread kernelpanic

You didn't mention which Galaxy S phone or if it's all of them.

FWIW, I've had no issues sending this type of URL through an SMS
gateway to the Samsung Epic Galaxy class phone - works as expected.

I do question the validity of the spaces in the query and suspect that
is the issue here.

I can send you a screen shot from an Epic showing my links versus your
links - mine look fine, yours look like your image.

I also sent the same text message to a diff phone (J2ME based) and the
link is underlined up to the first space but it includes the ?
sc=4KNZNSEN part in the link

Loosely related - in the past, I have had issues with some phones/
carriers when the URL string is rather long. There is the obvious
inherent SMS length limitations, but even when that is complied with,
I have seen some devices that accept the URL in the SMS, but then
truncate it between the SMS and the browser when the link is tapped -
some as short as 60 characters, some at 64 characters, some not at
all. However, I don't think that is the problem here since you are
saying it is happening at the ?

If by wireless connection you mean WiFi, yes, the WiFi radio gets
turned off while the phone is asleep. You will need to maintain a
WakeLock and a WiFiLock. And, bear in mind that the user may or may
not have an available WiFi connection wherever they happen to be.

If by wireless connection you mean mobile data, AFAIK that remains
on even while the device is asleep. In fact, one of the things that
can wake up the device is an incoming packet on an open socket on a 3G
connection.

If anyone start sniffing with strace then definitely such protection

actions that one should consider doing to keep 'hackers wannabe's

you shall be aware of its weakness. At the same point if you agree to

Re: [android-developers] Re: URL query string bug in SMS messages

BTW, it's been suggested to use a link shortening service - that would 
break intent filters, if they are used to launch the application.


What would work, is to use URL rewriting, so rather than using:

http://www.site.com/page?param=value

one would use something like:

http://www.site.com/page/param/value

A rewritten URL like the above would still work with intent filters to 
launch the application, if that's the goal.

FWIW, I've had no issues sending this type of URL through an SMS
gateway to the Samsung Epic Galaxy class phone - works as expected.

I do question the validity of the spaces in the query and suspect that
is the issue here.

I can send you a screen shot from an Epic showing my links versus your
links - mine look fine, yours look like your image.

I also sent the same text message to a diff phone (J2ME based) and the
link is underlined up to the first space but it includes the ?
sc=4KNZNSEN part in the link

Loosely related - in the past, I have had issues with some phones/
carriers when the URL string is rather long. There is the obvious
inherent SMS length limitations, but even when that is complied with,
I have seen some devices that accept the URL in the SMS, but then
truncate it between the SMS and the browser when the link is tapped -
some as short as 60 characters, some at 64 characters, some not at
all. However, I don't think that is the problem here since you are
saying it is happening at the ?

Hi,

Has anyone else stumbled upon a similar issue as seen in the following
screen shot :http://twitpic.com/3vpnzx

The problem is when a user sends a URL containing a query string, the
query string is not interpreted as part of the URL.

I've seen this happen to both my HTC Desire running 2.2 and on Samsung
galaxy S phones.

Does anyone know of a workaround or a fix for this?

Re: [android-developers] Re: Scheduling ideas


Interesting.

I take it by wireless you mean cellular?

My HTC Hero has an option for always on cellular data connection - I 
guess it's specific to HTC phones, as neither my Samsung Galaxy S or 
Motorola Milestone have that.


Is your phone made by HTC by any chance? If so, perhaps you could check 
that setting.

Neil,

That's pretty much how I test too, except my code lacks a check for
isConnected, only for null.

This is what I get in my app's log:

NetworkInfo: type: MOBILE[EDGE], state: CONNECTED/CONNECTED, reason:
apnSwitched, extra: internet.mts.ru, roaming: false, failover: false,
isAvailable: true

Two ideas:

- Check your phone settings, perhaps yours has some kind of sleep policy
for mobile data;

- Log the value you get by calling getActiveNetworkInfo into a file, and
examine later.

Hi Kostya.
Yes, the alarm gets called... it's just my own call which stops it
doing it's task. For example:
if(isNetworkAvailable(mContext)){
 // do stuff...
}
public static boolean isNetworkAvailable(Context context) {
ConnectivityManager connMgr = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = connMgr.getActiveNetworkInfo();
return(info != nullinfo.isConnected());
}
So this call tells me the network isn't available when the phone's
asleep. I guess I'll have to try another way of testing for the
network?

This is a call I make deliberately (I always check there's a

Depends on what kind of network connectivity you expect.
In my tests (Moto Milestone), WiFi doesn't get enabled when the phone is

[android-developers] Re: 2.3 Platform Google APIs missing Licensing Service..?

2011-02-05 Thread outofcoffee

LVL doesn't work for me on 2.3 either.

LogCat output:

01-27 00:21:46.455: INFO/LicenseChecker(1067): Binding to licensing
service.
01-27 00:21:46.465: WARN/ActivityManager(76): Unable to start service

More info:
Same code works on version 2.2 of the Google API emulator, but not 2.3
of the Google API emulator.

From 2.2:
01-27 01:00:12.979: INFO/LicenseChecker(562): Using cached license
response

From 2.3:
02-05 15:32:52.674: WARN/PackageManager(60): Unknown permission

Subsequently, a check to see if the

application returns false on 2.3 but true on 2.2.

This issue has been raised at

Re: [android-developers] Re: URL query string bug in SMS messages


Not sure if there are any spaces.

The SMS content is: http://www.site.com?param=value Test 2

It's not clear whether the  Test 2 is part of the URL. I would think 
not, because spaces in URLs are always encoded as %20 or +.


I suspect the issue is that the ?param=value is not highlighted, just 
the http://www.site.com;.

Yeah, I never noticed that. Looking at the regex that Linkify uses, it
will not honor spaces in query parameters, but it should honor %20

[android-developers] Issue 13044: Android Browser does not correctly support XMLHttpRequest streaming

2011-02-05 Thread kypriakos


Has this issue been resolved or are there plans to resolve it? It
seems that the issue that I have with the server response not being
read by the Android's native browser when I call a remote web service
could be related to this 4K buffering on the browser's side. Has
anyone else experienced this before when calling services using Ajax?

I have been asking questions regarding the browser for a bit now and I
don't seem to get much feedback from the list. Do developers opt to
use webview or other tools rather than the browser? Is the browser a
dead tool in the Android community?

Thanks again

[android-developers] Re: In app billing...

2011-02-05 Thread Maps.Huge.Info (Maps API Guru)

 I believe being able to provide refunds is important. When you go to a 
 real-world store

Since a user upgrading to a pro version isn't buying anything
tangible, it's more like going into a donut shop, buying a donut and
eating it. How many consumers ask for refunds at that point? Under
some circumstances, a refund is called for but not in the same way as
a consumer returning an unopened package that can be resold.

To me, issuing a refund for a software product is only to be done
under some unusual circumstance not because of buyer remorse. The
donut has been eaten and that's that.

Well, some devices have really weird settings, like the HTC fast boot
optimization for the Desire HD, which disables BOOT_COMPLETED. So at
least you can be aware of it. But since your phone is not an HTC

There is this:

http://developer.android.com/reference/android/net/ConnectivityManager.html#setNetworkPreference(int)

but i haven't had much experience with it, since my phone keeps the
mobile connection on at all times, as seen in the log entry I posted before.

What happens if you just go ahead and start your network operation?
Might cause the phone establish a connection just then, on demand. If
not, I suppose your code catches IOException already, right?

2011-02-05 Thread chcat

Mark, Thanks for the clarification.
I am interested in adaptive http live streaming, that is supposed to
be one of the great new features in Android 3.0.
I'd have to get some sort of live media streaming from Nexus One phone
within next 6months. I wouldn't want to try to re- invent the wheel
if that will be the part of media framework release. Any idea if that
part is functional in Gingerbread, or when Honycomb might be
available for Nexus?
Thanks again,

I believe being able to provide refunds is important. When you go to a 
real-world store

Since a user upgrading to a pro version isn't buying anything
tangible, it's more like going into a donut shop, buying a donut and
eating it. How many consumers ask for refunds at that point? Under
some circumstances, a refund is called for but not in the same way as
a consumer returning an unopened package that can be resold.


That's a different type of product, more like a health potion in an RPG 
game. You might call it a virtual consumable.



To me, issuing a refund for a software product is only to be done
under some unusual circumstance not because of buyer remorse. The
donut has been eaten and that's that.


For a virtual consumable, yes.

But I'm talking specifically about upgrading from lite to pro, which is 
not a consumable at all.


It's the right to use the software in a certain way, to repeatedly 
perform certain tasks, and is more like buying... hmm... a microwave or 
a washing machine, not a donut.

just to add more food for thought - there may be a problem here -
there are definitely some differences

Using this as a test URL

http://www.test.com?id=123abc

If I send it to the Epic from another phone - it does NOT consider the
query portion (?id=123abc) as part of the link

if I send it to the Epic from an email client (in this case
Thunderbird) which forces it through Sprint's SMS gateway - it DOES
consider the query portion as part of the link

[android-developers] Re: URL query string bug in SMS messages

Interesting notice that there is a difference.

From what we have seen so far, we haven't noticed a difference sending
the URL from one handset or from our SMSC.
Worth mentioning that this is the case of Finish operators.
I don't own a Samsung Galaxy phone myself, but the customers that have
reported issues to us have had the i9000 model.

At first I would have blamed the skinning interface of Samsung. But
when I've tried with HTC's Sense based phones, a Desire, the issue is
exactly the same.

I've yet to try replicate this issue on a vanilla Google device.

But either way. Shouldn't it be the receiving device that does the url
recognition? Or does actually sprint ad some additional tag around the
link?

In my business, I have a stated policy of No refunds under any
circumstances. I've had this policy for over 30 years and it has
served me well. I have the policy stated in several places and so far,
it hasn't been a problem. If you state this clearly then it shouldn't
be an issue with the consumers. Sure, you may scare away a few by
having this policy but the end result is less complaining and
customers who are more likely to be satisfied. I see no reason to
change this policy with apps. Besides, we're talking a couple of

  A rewritten URL like the above would still work with intent filters to

  Does anyone know of a workaround or a fix for this?

Looks like the value for both

NAVIGATION_MODE_LIST
NAVIGATION_MODE_DROPDOWN_LIST

appears to be the same.

The only affect of setting one mode or vs the other, (betweent these
two modes), is wether to show the titles or not. I suppose those can
be done through display options setting.

Re: [android-developers] Re: In app billing...

2011-02-05 Thread Kevin Duffey

So I have a few thoughts on this subject. I have been hoping ever since
apple introduced this feature for iPhone/iPad that Google would hurry up and
add this. I know of several developers that are making a huge sum more with
in-app virtual good purchases than their pro version ever sold. Because it's
so tightly integrated in the app, it's a very simple dialog to ok/cancel the
purchase and you keep using the app. I have not read the docs yet, I am
going to assume that this is the same experience android users will see...
they won't be taken out of the app to approve the payment correct?

To me, this is the holy grail of mobile apps for developers. I happen to
know of a few people in the micro transaction business, and the predictions
for this particular segment is astronomical. Tapping in to it therefore is
just a matter of finding that right use of it for any given app. Games
obviously are going to be the big winner with this feature, as virtual
goods, map packs and so forth are unmatched in consumption by end users. I
am blown away with how easy it is for someone to spend a buck to customize
their avatar look, or a buck for a avatar item.. few bucks to customize, etc
etc.

I am really hoping.. and if anyone has read and has a clear understanding of
what is going to possible.. that they have at least provided what apple has
in their API for both end users and developers. Apple for example shows the
top in-app purchases. Is there a way for the developer to get info on each
and every in-app purchase, to figure out what is selling good and what might
not be? Will the Market display the top in-app purchases? For the end user..
how does the in-app purchase go.. is it simply a dialog to approve/deny the
purchase? What if they have never bought anything yet? I see that Google and
ATT now allow for purchases to appear on their bill. I am hoping at least
for ATT that in-app purchases automatically go to their bill as well? Is
there any time frame on when Verizon, t-mobile, sprint and other carriers
around the world will support this?

2011-02-05 Thread nivedita arora

hi,
i really need help.
i am making a word game for college which uses  words of length 4 to
7.
i have a certain array of string containing words of length 4 -7.i
have to check if those words are valid english words or not.i was
earlier trying to implement database containing 4 tables each having
all possible for word of length 4,5,6,7 which were being added by
reading respective file of words i had made .

But its taking way too much time to create database for any user to
wait,and the app  times out.

so i started searching alternate ways..cant decide what should be done
and is best considering my req.
1)trie for dictionary
2)hashset for storing words of each length of 4,5,6,7
 (would using this be better than trie as i hv to access just  words
of length 4,5,6,7 only?)
3)some dictionary api(some preinstalled db whch i cud query)

pls any help would be really appreciated what should be selected?
i want to make an efficient game.pls suggest what should be done?
thanx in advance :)

I believe being able to provide refunds is important. When you go to a

Since a user upgrading to a pro version isn't buying anything
tangible, it's more like going into a donut shop, buying a donut and
eating it. How many consumers ask for refunds at that point? Under
some circumstances, a refund is called for but not in the same way as
a consumer returning an unopened package that can be resold.

That's a different type of product, more like a health potion in an RPG
game. You might call it a virtual consumable.

To me, issuing a refund for a software product is only to be done
under some unusual circumstance not because of buyer remorse. The
donut has been eaten and that's that.

For a virtual consumable, yes.

But I'm talking specifically about upgrading from lite to pro, which is not
a consumable at all.

It's the right to use the software in a certain way, to repeatedly perform
certain tasks, and is more like buying... hmm... a microwave or a washing
machine, not a donut.

[android-developers] Re: Where to put a broadcast receiver for a widget

If the widget initialization requires some calls to registerReceiver()
passing a null pointer to get the values where is the best place to be
doing this. In my case, I am maintaining Application state in an
Application subclass. In a sense my whole widget application has a
state. The state depends on some values that I can only get by
calling registerReceiver() passing the null value. The docs indicate
that not much processing should go on in the Application.onCreate()
method so I am not sure if this is the right place to do the
initialization. On the other hand it seems like keeping Wdiget
Application State in the App subclass is the right place for it,. (I
also have services, and activities associated with the Widget). Where
should the application state for a Widget be maintained? In the
Application subclass or in the Widget itself. I have decided to put
the state of the App Widget in an app subclass but not sure if this is
right, given I can't very well initialize everyting in the

If the Context passed into your onReceive() method is named ctxt, use:

ctxt.getApplicationContext().registerReceiver(null, myIntentFilter);

Then, you won't need service and extra overhead of starting it up.

I just remembered that I had a blog post on this:

Re: [android-developers] Re: Where to put a broadcast receiver for a widget

On Sat, Feb 5, 2011 at 5:19 PM, AndroidDevTime androiddevd...@gmail.com wrote:
 Where
 should the application state for a Widget be maintained?  In the
 Application subclass or in the Widget itself.

Neither. Ideally, an app widget has no state outside of data you
maintain for your application as a whole, which hopefully is in a
database or some other persistent store.

The Widget itself has no meaning. If you mean AppWidgetProvider, it
lives for milliseconds. If you mean the RemoteViews, they are
read-only, and so you cannot store state in them to be read out
later.

The Application object will live only as long as your process lives,
which could be for the same number of milliseconds that the
AppWidgetProvider instance lives.

Hence, anything related to an app widget that you want to live for
more than an eye-blink should be in a persistent store or be
re-retrievable from the OS. If you want to cache stuff in an
Application object or static data members, in the off chance your
process sticks around long enough to be useful, that's cool, just
watch out for garbage collection issues.

 I have decided to put
 the state of the App Widget in an app subclass but not sure if this is
 right, given I can't very well initialize everyting in the
 Application.onCreate() method.

Anything slow enough to cause a problem probably should be processed
by an IntentService, or possibly an AsyncTask kicked off by the
Application (I have never tried an Application-spawned AsyncTask).

[android-developers] How to Keep Widget Application Status/State

I have an Widget Application that also has Activities, and a heavily
used Service full of functions.  I would like to keep a global status
for the application.  This is app/widget specific state like say
STARTED, LEVEL1, LEVEL2 etc, so since the status is referenced in the
widget, the service, and activities I thought a static variable in an
Application Subclass might be good.  So my question is twofold.

1) Where should I keep such a state/status variable as a syncronized
static variable in an application subclass?

And

2) Its first initial value  depends on reading some values by calling
registerReceiver(null, intent) passing null for the receiver in order
to obtain some system values.  Where should I do this initialization.
The Application.onCreate() docs indicate that not much should happen
in this method. I am thinking in the Widget.update method can call
getApplication and perform the registerReceiver operation and then
update the static variable in the Applicaiton subclass.  Is this the
right place to initialize the application state?

Thanks

[android-developers] Re: converting to regular java

Well, someone could always come up with a port of the Android
emulator to native Windoze/Mac/Linux, and then it would be easy.
Otherwise, the UI, as usual, is the bottleneck.

Re: [android-developers] How to Keep Widget Application Status/State

You can use a lazy initialize Java Singleton, where you pass in a context in
case one is needed to recreate state.

If you need to keep a context reference, make sure to call
getApplicationContext and keep that instead, so you don't run into object
lifetime issues and leak memory (in case that Context is an Activity or a
Service, and it goes away before the process does).

The stuff about not doing much in the application's onCreate I take to be
more of an architectural suggestion than a real framework limitation, you
can probably do as much there as in any other callback (e.g activity
onCreate), subject to ANR timeouts.

[android-developers] Re: How to Keep Widget Application Status/State

Ok. Lets say that it goes into a static singleton, and say the status
is level2 and the application/widget gets shutdown.  I suppose I would
need to implement a saveState() method on the singleton, and detect
this shutdown somewhere so I could recover the correct state?   I
don't think there is any method on the Application that is guaranteed
to get called during such a shutdown.  There is terminate method but
this is not really called for sure.  The widget is long running, so
where would be the best place to save off the application status/state
during shutdown? or when process gets killed.

Thanks

 Service, and it goes away before the process does).

 The stuff about not doing much in the application's onCreate I take to be
 more of an architectural suggestion than a real framework limitation, you
 can probably do as much there as in any other callback (e.g activity
 onCreate), subject to ANR timeouts.

[android-developers] Re: How to Keep Widget Application Status/State

What is the advantage of using lazy initialize Java Singleton vs.
using subclass of application as the Singleton itself?  Since we
already have getApplication() available in most places

should the application state for a Widget be maintained? In the
Application subclass or in the Widget itself.

true, but what I was thinking is an app widget that is reflecting the
application's state.

Neither. Ideally, an app widget has no state outside of data you
maintain for your application as a whole, which hopefully is in a
database or some other persistent store.

The Widget itself has no meaning. If you mean AppWidgetProvider, it
lives for milliseconds. If you mean the RemoteViews, they are
read-only, and so you cannot store state in them to be read out
later.

The Application object will live only as long as your process lives,
which could be for the same number of milliseconds that the
AppWidgetProvider instance lives.

Alright, but what I really want is the app widget reflects the state
of the app. It makes no sense for the Widget to store the app state
off for the app to me. Perhaps the service, but then again it is
really the state of the app, not the state of the widget (although the
widget reflects it), nor is it the state of the service. So the point
is each component needs to reference the application level status
state, (even if it just needs it for few milliseconds), and yes it
needs to be stored, but it also needs to be kept in a synced/singleton
manner at all times.

Hence, anything related to an app widget that you want to live for
more than an eye-blink should be in a persistent store or be
re-retrievable from the OS. If you want to cache stuff in an
Application object or static data members, in the off chance your
process sticks around long enough to be useful, that's cool, just
watch out for garbage collection issues.

I have decided to put
the state of the App Widget in an app subclass but not sure if this is
right, given I can't very well initialize everyting in the
Application.onCreate() method.

registerReceiver(null, Intent) would be under 5 seconds for sure? I
have not seen any guarantees related to android functions.

Anything slow enough to cause a problem probably should be processed
by an IntentService, or possibly an AsyncTask kicked off by the
Application (I have never tried an Application-spawned AsyncTask).

[android-developers] Looking for L10nDemo sample

2011-02-05 Thread Eric Cloninger

The localization draft article at 
http://groups.google.com/group/android-developers/web/localizing-android-apps-draft
 
is a nice reference. There is a sample connected to the article, but I can't 
seem to get it. I get error messages when I try to access L10nDemo.zip. The 
other files that are associated with the article are available, but the 
source archive is not.  I've tried to find the archive using my favorite 
search engine and all the hits point back to the file on Google Groups.

Does someone have this file that they can share?

Thanks

[android-developers] Application Shutdown

I would like to handle application shutdown gracefully.  Whether the
user ends the application or the system decides the kill the process,
I want to know the best place to put hooks in the application to
detect and handle this.  I know that application level components have
lifecycle methods the conform to system events, but I really want the
best practice on this at the application level.  This is after all an
application level shutdown, so i want an app level(not just component
level) handling.

Not really sure where to put the global app shutdown code:

In Application.terminate() ?:  Not really guaranteed to get called.

In a service?:  I have n services.

In an activity? : ok but just for the view data.

The only thing I can think is to have a service dedicated to this
shutdown activity manage the application level data, but I don't
really want to start a service at a time when my app is getting
shutdown perhaps for resource consumption.

Perhaps one could  just let each component deal with it, however I
have shared data/state (that is not a preference) across the
components, and I see no reason why one of those components other than
the application (subclass) should be dealing with application global
data management.

There are none. Design your app such that you don't care about
application shutdown, whatever you consider that to be.

Save data when the user's no longer interacting with it.  And even
when they are.  As you point out, there are no guaranteed callbacks.
The system assumes that if you're idle, you can be killed.

Why do you have a FrameLayout?

Why do you have android:orientation=vertical in your FrameLayout,
considering that FrameLayout does not honor that attribute?

I have implemented the WebChromeClient and WidgetViewClient.

That's WebViewClient.

I have
implemented the onTouchEvent and passing the touch events to the
WebView.

That seems unlikely to work well.

The problem i am facing is am not able to scroll inside the webview.
For example, the content is some 5 lines then am able to see only 3
lines and not able to scroll.

The touch events go to Webview, first action_down and then
action_move, am not able to get what wrong am doing??

What are you trying to achieve by intercepting the touch events?

Since WebView knows how to scroll on its own, I would recommend you
simply get rid of the FrameLayout and your own touch handling, and let
WebView do what it does naturally.

[android-developers] Re: Changing audio path to earpiece from speakerphone

2011-02-05 Thread Indicator Veritatis

I have seen this question answered before in this group. Do a search
on it. I think the answer was 'no'. The reason it cannot be done (or
at least cannot be done simply) is that the phone's in-call audio and
its multi-media audio are considered separate paths, the former is
carefully guarded against tampering.

But rather than rely on my answer, do the search: just don't be too
disappointed if you find that the only way to do it is to modify the
phone application software on your own ROM.
