 Write a Web service that connects to the database and runs on some

 REST-style APIs, since Android does not have built-in support for SOAP
 or XML-RPC.


for the latter, one can use very thin client

[android-developers] Re: Disable Home Key?

[DroidBy]

Hi Sean Hodges,

I am happy that you give me a clue on this, however I am not able to
open the link that you post, it will redirect me to a blank webpage.
Can you repaste the link? or the main link that I can browse into the
sub-pages of this?

Btw, Do you have any idea on the KeyGuardManager? Can I use that to
disable the HOME key?

Thanks. :)

 Have you taken a look at the existing projects out there?

 MyLock seems to achieve this using a lock mediator, to intercept a
 forbidden action and react to it:

 Can't say I've tried anything like this before though.

[android-developers] Re: Use of intents

[Shekhar]

Hi Mark,

Could you please provide some pointers on how to implement listener
object for the service.

Shekhar

  Now the service running in the background has to pass data to the

  Intent intent = new Intent(Service.this, Activity.class);
  intent.putExtra(Data, data);
  intent.setAction(Intent.ACTION_ATTACH_DATA);
  sendBroadcast(intent,null); (Do I need to broadcast the intent???)

  In activity I have done following things:-
  Implemented broadcast reciever:

  private BroadcastReceiver mBroadcastReceiver = new
  BroadcastReceiver()
  {
  @Override
  public void onReceive(Context context, Intent intent)
  {
  if (Intent.ACTION_ATTACH_DATA.equals(intent.getAction()))
  {
  Bundle extra = intent.getExtras();
  float Data[] = extra.getFloatArray(Data);
  update(Data);
  }
  }
  }

  Also registered the broadcast reciever in the OnStart function as
  below:-

  public void onStart()
  {
  super.onStart();
  IntentFilter filter = new IntentFilter();
  filter.addAction(Intent.ACTION_ATTACH_DATA);
  registerReceiver(mBroadcastReceiver, null);
  }

  Is this the right way of meeting my requirements.

 It's certainly one way. An alternative is to have the activity register
 some sort of callback or listener object with the service, that the
 service uses when events need to be propagated to the activity. That
 will be more efficient and more private than your implementation, but it
 involves a bit more code, usually.

Strange, the link works for me. I linked to a formatted page on the

the file directly:

Sorry, I have no idea. I'm not familiar with the key guard stuff. Take
a look at some of the other screen locking code out there, there are
quite a few projects on Sourceforge and Google Code.

[android-developers] Unexpected MEDIA_BUTTON action broadcasting when unplugging headset

[Urakagi]

I'm writing music app, and find a confusing issue about headset
buttons.
My app has a BroadcastReceiver class to receive headset button
controls, with

action android:name=android.intent.action.MEDIA_BUTTON/

as intent filter.

The problem is, when I unplug a wired headset slowly, sometimes
Android will broadcast MEDIA_BUTTON intents with
KeyEvent.KEYCODE_HEADSETHOOK. It equals to a normal play/pause button
pressing, so my app starts playing automatically.
But the default Music app does not come up, and I can't find anything
checking or preventing this in the Android source code.
Anyone have idea about how to avoid this? Thank you very much!

[android-developers] Re: Task activity stack always reset when launched from Home

[Neha]

Hi,

Does anyone have any updates on this issue? I'm facing the same
problem with my activity when launchMode=singleTask.
 - Launcher - Activity A (singleTask) - Activity B (standard)
 - Press HOME
 - Long-press HOME or go to Launcher
 - Activity A (B's onDestroy called)

adb shell dumpsys activity shows only Activity A in the stack for
this task. The intent flags are:
Long press HOME - FLAG_ACTIVITY_NEW_TASK,
FLAG_ACTIVITY_BROUGHT_TO_FRONT and FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY
Launcher - FLAG_ACTIVITY_NEW_TASK, FLAG_ACTIVITY_BROUGHT_TO_FRONT and
FLAG_ACTIVITY_RESET_TASK_IF_NEEDED

Any pointers on how to fix this would be helpful.
Thanks!

 When you say launch do you mean launching from Eclipse?  If so, there is a
 bug in older SDKs where this would use the wrong intent so when you later
 launch it from the launcher you would get a new task.

 You can use adb shell dumpsys activity to see the current state of the
 activity stack at whatever point you want to help diagnose what is going on.

[android-developers] Which View/Layout does the Market app (1.6) details activity use?

[westmeadboy]

I want to do something very similar (in terms of appearance) to the
app details activity of the Market app.

It looks like a cross between linear layout (not all rows the same),
list (scrolling nature), preferences (headings).

My guess is its a linear layout in a scroll view (ignoring activity
header/footer) and the headings are just hard coded...

Is that the best way to do it?

int[] pid = new int[1];
  FileDescriptor   fd =
(FileDescriptor)createSubprocess.invoke(
null, /system/bin/cat, /sdcard/chunk.3gp,

i can read bytes from fd and it seems working fine but when i pass it
to the mediaplayer as datasource.
it doesn't show anything. (this is just 1 sec video)
same video works fine with direct path but i need to decrypt the file
bytes by bytes while its playing.
i thought this solution might help me but no luck so far.
can anybody guide me to the right direction how can i decrypt the file
while playing ?
or do i need to change in native code and build the opencore (pv
player ) separately and any change in there?

please help

[android-developers] [Android-developers]How many SurfaceHolder objects can be created in one activity having one view?

[Latha Shivanna]

Hi All,

I need to have an app where i can play both video and audio using
mediaplayer APIs.
But my problem here is , for video . i have to use
SURFACE_TYPE_PUSH_BUFFERS and pass this to mp.setDisplay().

SurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

Where as, An audio file can not be played with
SURFACE_TYPE_PUSH_BUFFERS being On.

What is the best solution to achieve this?

Is it possible to have more than 2 SurfaceHolder objects can be
created in one activity having one view?(one for audio with no
SURFACE_TYPE_PUSH_BUFFERS and other one is for Video)

Please do advise.

thanks
Latha

[android-developers] Re: Piracy sucks, or does it?

[Hekki]

Hi,

People cheat, it's in our human nature, it's even an economic rule :
Individuals try to get the most with their limited resources. So if
they can have something for free, they will.

The problem is not really to fight this, because we'll never win (RIAA
anyone : ), it's to find a way to leverage it and to find an
equilibrium.

I'm french and here some of our stand-up comedians are upset with
youtube and the likes because youtube makes money on they're work and
they don't see a single penny of it.
The thing is, it's not true at all : I bought two tickets to one of
those stand-up comedy show after I've spent a couple of hours looking
at various bits on youtube. I had stumble on it and didn't even know
the comedian in the first place.
My point is, I'll never buy something I don't know exists.

I'm not saying to do nothing about it, i'm saying don't loose your
sleep over it and certainly don't spend half your production time and
budget on securing your app.
Hackers, the real ones, the ones that cracks your security codes and
then gives away your cracked app, hack because it's easy for them and
fast and sometimes represent a small challenge.
They are not 15 years old, they are computer engineers with degrees
and too much time on their hand.
Music and DVD industry has put several BILLIONS of dollars in DRMs and
you can still enjoy any movie in divx can't you ? And YOU don't have a
few billions dollars, do you (if you do, maybe we can meet : ) ?

So put mild protection in place so that the average user has the
incentive to buy.
Use guilt techniques (help our developpers, you enjoyed our game help
us do more, ...)
Release a free version with ads,
Release your own pirated version with a scary time bomb (after 10
usages : You are using a pirated version of this app, next launch
will erase all your data from your phone. Don't ever actually put the
threat to execution !)
And if you don't want to go free with ads  on the market, just make it
your pirated version :D

Good luck with your work and your apps.

I do not know what a PITA is but I agree.

Changing your phone time just to play a game or  use an app is to much
work to worth the trouble.
If someone does that, then he is either very, very poor, or very very
pathetic with avarice and you won't get anything from him anyway.

You can't. You can create your own soft keyboard, and convince users to
switch to it -- but then you will need to create a *complete* soft
keyboard, since their choice is for their phone, not your application.

 I actually need to show
 and react to my custom view.

Then make your soft keyboard be part of your custom view. Sounds like
12 Button widgets would do the trick.

[westmeadboy]

Thanks Mark - that MergeAdapter will definitely come in handy for some
other things I'm doing.

In the Market activity, only the Comments section can really be
described as a list.

So wouldn't the MergeAdapter only be useful in the situation where
there is more than one sublist?

In my case, I don't really have any sublists. Its a bunch of rows each
with their own header and each (below-each-header-part) very different
from one another.

I've never used ScrollView before. Are there any potential pitfalls
using a LinearLayout within a ScrollView?

I go the server-registration route. The app in question already needs
net access, and I have a server that it talks to already, so I just
created a narrow MySQL table server-side and a simple PHP script to
interface with it. Essentially, I store the IMEI, app version number,
and the date of first use, and use that to validate the trial period.
My original implementation didn't include version number, but I soon
realized that it was desirable to let people re-trial when I released
a new version.

I've also decided not to bother with any encryption on the trial
period validation. I recognize that my approach is vulnerable to MITM
attacks, but it's sufficient to keep honest people honest; if
someone's going to that much trouble to screw me out of $2, there's
not much hope, is there? Besides, the whole Android-market piracy
aspect is a much bigger security hole. It's far more likely that
someone will simply download my license app from a warez site than
bother with cracking my validation routine.

That is a misconception. Try using your D-pad or trackball or whatever

It is useful anyplace where you have the need for a ListView where the
content does not all come from a single adapter. That could be headings.
That could be a mix of fixed rows (e.g., Flag as inappropriate) and
data-driven rows (e.g., the comments). It could be both. It could be
something else.

 In my case, I don't really have any sublists. Its a bunch of rows each
 with their own header and each (below-each-header-part) very different

If the non-header rows are to be selectable and/or clickable, then you

You cannot have scrollable things inside scrollable things. Hence, you
cannot have a ListView inside of a ScrollView, for example.

I see that the description section is not selectable and assume it is

selectable or not...

In my case, some rows are selectable and others have views within them
that are selectable (think of a displayed sentence where individual
words are clickable).

Given this, and if I understand you correctly, then the MergeAdapter
is the best way to go?

[android-developers] Re: Dialog goes away on click of search button

[Bolha]

Hey, Amit!

Specifically to the search button problem, I've found the following
solution:

case DIALOG_PROGRESS_SPINNER:
progressDialog = new ProgressDialog(this) {
@Override

public boolean onSearchRequested() {
return false;
}
};

progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressDialog.setMessage(Loading);
progressDialog.setCancelable(false);

return progressDialog;
}

As the code above, try to override the onSearchRequested in the
ProgressDialog class (or any other class you want no to be interrupted
by the search box). If you return false, the event is invalidated and
the search button isn't shown. But, for income calls and other events
that interrupt you application, the dialog probably will be hidden.
I was trying something related to the android:configChanges=..., but
without success. If you find something that solves your problem in a
more general way, please, let us know (hehe, I've just found my app
suffers from something similar...)

Thanks for the attention!

Inserting a try {} catch {xxxException ...} in the code an be hard...
if the crash occurs in a place we don't expect/suspect of not being

A solution for Google team, would be in the Manifest.xml to add

So, for each Force Close we could receive a mail from Google  (not

At least we could track the number of crash, check if they decrease

 You can't. You can create your own soft keyboard, and convince users to
 switch to it -- but then you will need to create a *complete* soft
 keyboard, since their choice is for their phone, not your application.

  I actually need to show

 Then make your soft keyboard be part of your custom view. Sounds like
 12 Button widgets would do the trick.

[android-developers] Re: Which View/Layout does the Market app (1.6) details activity use?

[westmeadboy]

I think you're right, it could get messy.

Having said that, I think there is a good case for creating a custom
widget like LinearLayout2ListView (i.e. extends ListView and takes a
linear layout resource as an argument).

A man of your talents Mark, could polish that off in about half an
hour :)

[android-developers] Re: Android, send me logs! - code library for detecting force-close and sending logs

[Streets Of Boston]

I haven't made it public yet (i will at some point), but i have a
similar system for my apps.

The process of my activities registers itself by calling
Thread.setDefaultUncaughtExceptionHandler(uncaughtXcptHandler) and
binds to service that i wrote that runs in a different process (since
my app will be dying because of an exception, it's tricky to properly
handle the exception in the dying process itself).

Then in the uncaughtXcptHandler.void uncaughtException(Thread t,
Throwable e), I write out an error-log file with the stack-trace and
some other info. Then i call an asynchronous method on my service that
will pop up a dialog allowing the user to send me the error report or
not. If the user clicks 'Yes', then the error-log file is read and
sent to my webserver. My webserver then sends me an e-mail. This way,
users can remain anonymous (no e-mail/reply address necessary).

I let my app die immediately after calling the asynchronous method. If
my app couldn't bind to the service for any reason, the old and
trusted force-close message from Android is shown instead.

 Hi fellow Android developers,

 How many times have you asked users to send you the logcat result to
 track down a nasty force-close?  How many users have actually replied?

 It's not that users are lazy or busy.  Having to run the logcat
 command or download an external log collector app just means too much
 trouble for them.  It should be much simpler.  It should be just one
 tap.

 In fact I'm surprised (or being ignorant) that an easier error
 reporting mechanism has not existed yet in the Android API, especially
 for the infamous force-close.  That is why I coded and open-sourced
 Android, send me logs!, a small code library that makes it easy to
 detect force-close and send logs from within your own apps.  You can
 program it to report errors with just one tap, and also include your
 own tracing information.

 Please check it out athttp://code.google.com/p/android-send-me-logs/.
 It's still in very early stage, and I would appreciate your critism,
 suggestions, comments, or even code contributions.

[android-developers] Ringtone.stop() wont work?

[draf...@gmail.com]

I currently start a Ringtone on Android and it plays fine.

However when I try to stop the ringtone it doesn't stop or atleast
doesn't stop straight away, it will keep in playing until it just
plays out.

Here is how I set up the Ringtone:

int rm = audio_service.getRingerMode();
int vs =
audio_service.getVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER);

android.os.Vibrator v = (Vibrator)
getSystemService(Context.VIBRATOR_SERVICE);

if ((rm == AudioManager.RINGER_MODE_VIBRATE ||
(rm == AudioManager.RINGER_MODE_NORMAL  vs ==
AudioManager.VIBRATE_SETTING_ON)))
v.vibrate(vibratePattern,1);

if (audio_service.getStreamVolume(AudioManager.STREAM_RING)  0)
{

oRingtone = RingtoneManager.getRingtone(this,
Settings.System.DEFAULT_RINGTONE_URI);
oRingtone.setStreamType(AudioManager.STREAM_RING);
oRingtone.play();

}

And here is how I try to stop it

if (CallDialogActivity.oRingtone != null) {
  Log.d(RINGTONE, Into Ringtone if);
  Ringtone ringtone = CallDialogActivity.oRingtone;
  oRingtone = null;
  ringtone.stop();
}

Has anyone come across similiar problems or see any mistakes in my
code?

[android-developers] Re: Free Version of App

[Streets Of Boston]

Thanks for the info! Especially the bit about the re-trial is
interesting.

But i have one question:
You use the IMEI number. What if the user gets a new phone?
Aren't app downloads tied to a user's Google Checkout account. If the
user gets a new phone, uses the same Google Checkout account, he/she
has to buy your app again. Shouldn't you use the 'ANDROID_ID' instead?

 I go the server-registration route. The app in question already needs
 net access, and I have a server that it talks to already, so I just
 created a narrow MySQL table server-side and a simple PHP script to
 interface with it. Essentially, I store the IMEI, app version number,
 and the date of first use, and use that to validate the trial period.
 My original implementation didn't include version number, but I soon
 realized that it was desirable to let people re-trial when I released
 a new version.

 I've also decided not to bother with any encryption on the trial
 period validation. I recognize that my approach is vulnerable to MITM
 attacks, but it's sufficient to keep honest people honest; if
 someone's going to that much trouble to screw me out of $2, there's
 not much hope, is there? Besides, the whole Android-market piracy
 aspect is a much bigger security hole. It's far more likely that
 someone will simply download my license app from a warez site than
 bother with cracking my validation routine.

Mike - I think Apple's approach may be good for Apple, and probably

developers?  If you suggest it here, we could definitely consider to
add it to the library if appropriate.
   


What's nice about Apple's approach here is that developers
don't have to do anything... it's a good way of improving the code
quality for *all* apps. I was pretty surprised and happy when it
came online a month or two ago because it confirmed that what
was crashing across our user base were known issues. Most of
the battle is getting *any* information about how the app is
behaving in the field, so the auto-crash reports are really nice.

I don't think there's an inherent conflict with Android's openness.
The crashes are anonymized, and developers and users do chose
to go through the Android Market -- which unlike Apple isn't the
only way to get apps.

I should say that I don't think of this as an either/or with what you're
doing though. Apple's just pulling up crash dumps, whereas what
you're doing is allowing big chunks of the log to be sent back. There's
room for both of these to exist at the same time.

[android-developers] Watching Activities - Updating their UI OR notify

[sperfect]

I'm just joinning the community, so Hello, Android

I thought it could be useful when browsing an Application (e.g. one
just installed) to be able to have information about the presence of
OptionsMenu and ContextMenu.
So that the user can know visually if Menu Button pressing button  or
long touching on a View can provide him more options, without having
to try every element on the screen.
I believe its useful feature for a comprehensive and easy HCI.

I'm trying to implement this idea through the API, with something like
Service and/or a Receiver, listening for Window/ Stack changes.

1) What should a Receiver listen about for such changes or, if no luck
in that, which System Service could provide me with an approproate
listener? Ofcourse an event is much more preferable than a power-
consuming Timer looking for changes.

2) Having caught the top Activity, is there a way to updateits UI
elements, for example dim bright shortly a View or mark it somehow.
This a less important problem, but equally intrested. Could be
bypaseed with a Notification of some type, but with carefull design
should be very pleasant..

Are these issues dealt through the API, or only with FrameWork level
work?

Thank you in advance,
Stelios Chatziefstratiou

[android-developers] How to get rid of WebHistoryItem instances to avoid memory leak?

[kknight]

My application often experienced OutOfMemory exception. To trace
memory leak, I got memory dump from my application process and
examined it in Eclipse Memory Analysis.

The tool gave me a report of potential memory leak. The report is
listed below. The report said there are many
android.webkit.WebHistoryItem instances in the process and the used a
lot of memory. My application has two activities. Activity A starts
Activity B, and B finishes when a button on Activity B is pressed.
Only Activity B contains a WebView. And this activity only opens one
HTML page each time. In the code, I cleared the web history when the
Activity containing the WebView finishes:

public void onDestroy() {
super.onDestroy();
m_storyWebView.clearCache(false);
m_storyWebView.clearHistory();
}

When I got the memory dump, Activity B is closed. Now the question is,
why there are still many WebHistoryItem existing in the process. And,
how can I get rid of the WebHistoryItem instances completely?

Thanks.

[android-developers] AutoCompleteTextView and show suggestions

[Steven]

Hello,

If I have an EditText, it shows suggestions of words automatically
when typing.  For example, when I start typing Tra, it suggests words
above the keyboard such as travel, training, etc.  However, if I make
the field an AutoCompleteTextView, I can get it to drop down
suggestions of previously entered values like Trader Joe's.

The problem is the suggestions above the keyboard are gone now so it
makes it more difficult to enter longer names, especially with
multiple words.  Any idea on how to get both to work at the same time?

Thanks,
Steve

[android-developers] Notepad tutorial questions about calling super

a constructor but not with a method)?

Also, if you return true in method 2, does that mean that super is
never called b/c you exit the switch statement immediately?  If you do
exit, then you're not chaining up to the superclass' method, which I
thought you always want to do.  I'm not even sure what the superclass'
onOptionsItemSelected() does anyway.  Does everyone understand every
line of code or should I just stop trying to analyze what every
parameter means and just sort of follow a formula?  I guess that I am
finding Android extremely hard to understand from the documentation.


METHOD 1
@Override
public boolean onCreateOptionsMenu(Menu menu) {
boolean result = super.onCreateOptionsMenu(menu);
menu.add(0, INSERT_ID, 0, R.string.menu_insert);
return result;
}

METHOD 2
 @Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case INSERT_ID:
createNote();
return true;
}

return super.onOptionsItemSelected(item);
}

Thanks!

[android-developers] Bluetooth A2DP/AVRCP profiles on Android

[Loco Moco]

Hello,

I would like to develop a software using Bluetooth A2DP/AVRCP profiles
on Android.
I could not find the related API on the developer's website at this
moment.
But, I found a product by Sybase below.
http://www.sybase.com/detail?id=1064424
Do we have any other option?
Thank you very much in advance.

 I thought it could be useful when browsing an Application (e.g. one
 just installed) to be able to have information about the presence of
 OptionsMenu and ContextMenu.
 So that the user can know visually if Menu Button pressing button  or
 long touching on a View can provide him more options, without having
 to try every element on the screen.
 I believe its useful feature for a comprehensive and easy HCI.

This would have to be implemented in the operating system. It cannot be
implemented via an SDK application.

[android-developers] Developer Phone Number Listing

[polyclefsoftware]

When I first started publishing Android apps as an indie developer, I
posted my phone number on the app's submission page, thinking it would
not be listed publicly. When I found out that it was, I removed the
number from the app listing. I don't have the resources to handle
phone support, and much prefer to handle support via email. Besides,
there is no requirement that we provide phone support, as long as we
provide support in some way, correct?

Anyway, these days I'm getting fewer phone calls, but I'm still
getting calls. We are required to list a phone number in our developer
profile, but it is stated that this is used for Google to contact us
directly in case there are issues.

So where are users still getting my phone number, and how can I make
sure it's not listed?

You are correct. Intercepting incoming and outgoing email messages
across the board is considered malware on most platforms, so I for one
am grateful for this.

Email clients are welcome to implement a plug-in or add-on architecture
to allow third-party extensions. Such extensions would not have a
blanket ability to intercepting incoming and outgoing email messages
for the OS, but particular to that client. This is the approach taken by
Microsoft Outlook (leastways, the last time I did Outlook add-ons),
Mozilla Thunderbird
(https://developer.mozilla.org/en/Extensions/Thunderbird/HowTos), etc.

If you feel such a plug-in architecture is important, I would start with
third-party mail clients (e.g., K9) and work with them to implement it
and come up with a de facto standard. This will help anyone who uses
those apps or buys a device with those apps pre-loaded. After
demonstrating the value in real life, you may find it easier to work
with the core Android team to implement the same architecture for the
native email application, and the Gmail team may at some point elect to
follow it as well.

[android-developers] Re: Android, send me logs! - code library for detecting force-close and sending logs

[dadical]

For those of you that are comfortable using Flurry, a similar approach
works nicely.  Flurry already collects uncaught exceptions, but for
some reason doesn't actually log the stack trace.  To get around this,
I add an exceptionHandler that logs a Flurry event with the stack
trace as a parameter, like this:

OutputStream lOS = new ByteArrayOutputStream();
PrintStream lPS = new PrintStream(lOS, true);
t.printStackTrace(lPS);
lPS.flush();
MapString, String lArgs = new HashMapString, String();
lArgs.put(stackTrace, lOS.toString());

SharedPreferences lPrefs =
PreferenceManager.getDefaultSharedPreferences(pCtxt);
if(lPrefs.getBoolean(PREFS_REMOTE_DEBUG, true)){
FlurryAgent.onEvent(FLURRY_EVENT_UNCAUGHT_EXCEPTION, 
lArgs);
}

One big advantage of this approach is that Flurry collects lots of
metrics w.r.t. the frequency, timing, and sequencing of the events.
Works very, very nicely.

 my app will be dying because of an exception, it's tricky to properly
 handle the exception in the dying process itself).

 Then in the uncaughtXcptHandler.void uncaughtException(Thread t,
 Throwable e), I write out an error-log file with the stack-trace and
 some other info. Then i call an asynchronous method on my service that
 will pop up a dialog allowing the user to send me the error report or
 not. If the user clicks 'Yes', then the error-log file is read and
 sent to my webserver. My webserver then sends me an e-mail. This way,
 users can remain anonymous (no e-mail/reply address necessary).

 I let my app die immediately after calling the asynchronous method. If
 my app couldn't bind to the service for any reason, the old and
 trusted force-close message from Android is shown instead.

[android-developers] what is the CRITICAL POINT of view layout to get hit by StackOverflowError exception

[HeHe]

it is frustrating to get StackOverflowError exception when i just call
LinearLayout.setBackgroundResource(wallpaper) trying to to beautify
background of an activity.

after i comment out the setBackgroundResource() call, the exception
has gone.

it makes me wonder if my view layout has (easily) reached a critical
point of stack size limit.

could android team raise the stack size limit so that such a
background beautification wont get hit by the exception?

thanks!

Guys,

I almost there of what i want to do but i am stuck at a point where I need
some expert pointers

this is what i do so far

I have rectangle white box

on cliking the rectangle I will draw a toolbar beneath the box and also call
relayout to accomodate the toolbar ( size+100) ( i used surfaceview and in
secondary thread i draw the toolbar)

on click again on rectangle box it will disappear the toolbar and also has
to resize the layout to original size (ie size-100) this is where I get
stuck.

I can disappear the toolbar however I cant call relayout either from
secondary thread (says cant call from secondary thread).

So I created a while loop in onlayout( this is where i create a thread to
draw the toolbar)  if i call requestlayout after while loop ends it doesnt
do anything it doesnt call onmeasure etc.

Please help me where I am doing wrong.

Use hierarchyviewer both to determine your View hierarchy depth and
determine where you may be able to consolidate some containers, to
reduce the hierarchy depth and in turn eliminate your stack size problem.

One of the reasons I rail against the use of activities as the contents
of tabs, for example, is because doing so is very wasteful from a View
hierarchy standpoint. Just switching those to be Views in tabs, rather
than Activities in tabs, can clear up problems.

[android-developers] Any built-in intent for viewing a single image?

[Mark Wyszomierski]

Hi,

Is there a built-in intent which will let you pass it the path of an
image (png or jpg) and show it full-screen with panning / zooming
controls? Basically the same controls WebView has, but only for a
single image. I saw that iPhone has something like this, just
wondering if there's already something like this on android before
writing a new one,

Thanks

 wondering if there's already something like this on android before
 writing a new one,

The Gallery has an activity for that. However, that probably only works
for images in the MediaStore, and I don't think it is documented. The

[android-developers] Re: Obtain unicode string for Roslien Language

[Bob Kerns]

The Unicode Consortium has not addressed non-human languages. Not even
Klingon, whose script has been around for 30 years, even longer than
Unicode!

But if you Google unicode klingon, you can find how people have
addressed this for Klingon, e.g. using the Private Use area.

I'd also look around for a tool to examine the content of a .TTF file,
and identify what code points it assigns its characters to. If it does
NOT use a Private Use area, I'd remap it so it did so. Otherwise, it
will conflict with other characters. On the other hand, you'll also
need an input method to type them!

Re: FW: [android-developers] Re: FormatDateTime

Reflection is an old computer language term. Think of it as

Languages such as C and C++ don't have it. Java, Lisp, and many
scripting languages do.

 Mark (et. al. interested parties):

 Thank you for the example on reflection.  I got it working and thought it
 might be prudent to share my results w/ the world so the completed code is
 below.  For the record, this date value (as a string) is being retrieved
 from a SQLite database and the function formatDateTime() is used in a custom
 adapter for display of the date for each record in a ListView.

 This compiles in Eclipse using Android 1.5.  This allows me to set a minimum
 sdk version of 2, while still utilizing this really nifty date display
 function.

[android-developers] Re: Android, send me logs! - code library for detecting force-close and sending logs

[Bob Kerns]

I take it a step further, and send one event for each exception cause
(up to three).
I also process the stacktrace to make it more compact (taking out
filenames, removing package prefixes that I expect, etc.) so that more
trace fits within Flurry's limits.

I find it useful already, even though my app's not on the market yet.

Flurry's tools aren't quite ideal for this. You'd like to
automatically cluster errors, and present each one with a count, with
a graph and history available, and links to individual event traces.

I've done similar stuff in the past for server applications. It
really, really pays off.

On Feb 26, 8:58 am, dadical keyes...@gmail.com wrote:
 For those of you that are comfortable using Flurry, a similar approach
 works nicely.  Flurry already collects uncaught exceptions, but for
 some reason doesn't actually log the stack trace.  To get around this,
 I add an exceptionHandler that logs a Flurry event with the stack
 trace as a parameter, like this:

                 OutputStream lOS = new ByteArrayOutputStream();
                 PrintStream lPS = new PrintStream(lOS, true);
                 t.printStackTrace(lPS);
                 lPS.flush();
                 MapString, String lArgs = new HashMapString, String();
                 lArgs.put(stackTrace, lOS.toString());

                 SharedPreferences lPrefs =
 PreferenceManager.getDefaultSharedPreferences(pCtxt);
                 if(lPrefs.getBoolean(PREFS_REMOTE_DEBUG, true)){
                         FlurryAgent.onEvent(FLURRY_EVENT_UNCAUGHT_EXCEPTION, 
 lArgs);
                 }

 One big advantage of this approach is that Flurry collects lots of
 metrics w.r.t. the frequency, timing, and sequencing of the events.
 Works very, very nicely.

   In fact I'm surprised (or being ignorant) that an easier error

   Android, send me logs!, a small code library that makes it easy to

[android-developers] Re: Free Version of App

[Bob Kerns]

I think in this situation, the IMEI is a better choice for identifying
when a trial has expired. You'd like to let them try your app on their
new fancy faster phone with the bigger screen!

The ANDROID_ID is a better choice (if it really is tied to the account
and not the phone?) if you're checking a paid license. But is there
value in doing that? It would seem to simply duplicate the fact that
they'd done the purchase in the market, and not provide any additional
security.

The IMEI approach works even for phones with no Market access, if
you're looking to sell your app via other channels. Does the
ANDROID_ID exist on devices even when there's no Marketplace?

On Feb 26, 7:13 am, Streets Of Boston flyingdutc...@gmail.com wrote:

 Aren't app downloads tied to a user's Google Checkout account. If the
 user gets a new phone, uses the same Google Checkout account, he/she
 has to buy your app again. Shouldn't you use the 'ANDROID_ID' instead?

Mark, thank you so much for the pointer and information!!

you are right on the tabs and activity. the view hierarchy depth of my

2). how does setBackgroundResource() increase the depth or memory

 Use hierarchyviewer both to determine your View hierarchy depth and
 determine where you may be able to consolidate some containers, to
 reduce the hierarchy depth and in turn eliminate your stack size problem.

 One of the reasons I rail against the use of activities as the contents
 of tabs, for example, is because doing so is very wasteful from a View
 hierarchy standpoint. Just switching those to be Views in tabs, rather
 than Activities in tabs, can clear up problems.

For StackOverflowException, the depth is more critical than the total,

It presumably triggers a different code path that makes more/deeper
nested set of calls.

[android-developers] Re: Intercepting incoming/outgoing email messages

While I can understand your opinion, I'll have to disagree.  See these
below links:

http://www.blackberry.com/developers/docs/4.5.0api/net/rim/blackberry/api/mail/SendListener.html
http://www.blackberry.com/developers/docs/4.5.0api/net/rim/blackberry/api/mail/event/ViewListener.html

Maybe the insecurity you refer to comes from the core values of the
OS?  I don't know enough of Android to offer up an opinion, but I know
enough of the Blackberry OS to say that I've never heard of any
malware being installed that causes an issue, as there are avenues
of recourse and finding out who was directly responsible for anything
in the wild that was released.  As it is, the most secure OS allows
email interception (and, imho, for good reason), which directly
refutes the reason you put forth as the reason you are grateful for
this.

 You are correct. Intercepting incoming and outgoing email messages
 across the board is considered malware on most platforms, so I for one
 am grateful for this.

 Email clients are welcome to implement a plug-in or add-on architecture
 to allow third-party extensions. Such extensions would not have a
 blanket ability to intercepting incoming and outgoing email messages
 for the OS, but particular to that client. This is the approach taken by
 Microsoft Outlook (leastways, the last time I did Outlook add-ons),
 Mozilla Thunderbird
 (https://developer.mozilla.org/en/Extensions/Thunderbird/HowTos), etc.

 If you feel such a plug-in architecture is important, I would start with
 third-party mail clients (e.g., K9) and work with them to implement it
 and come up with a de facto standard. This will help anyone who uses
 those apps or buys a device with those apps pre-loaded. After
 demonstrating the value in real life, you may find it easier to work
 with the core Android team to implement the same architecture for the
 native email application, and the Gmail team may at some point elect to
 follow it as well.

                         progressDialog.setCancelable(false);

                         return progressDialog;
                 }

 As the code above, try to override the onSearchRequested in the
 ProgressDialog class (or any other class you want no to be interrupted
 by the search box). If you return false, the event is invalidated and
 the search button isn't shown. But, for income calls and other events
 that interrupt you application, the dialog probably will be hidden.
 I was trying something related to the android:configChanges=..., but
 without success. If you find something that solves your problem in a
 more general way, please, let us know (hehe, I've just found my app
 suffers from something similar...)

 Thanks for the attention!

 On clicking of 'search' button the search box and keyboard pops up,
back button hides it and shows my activity which is always in the

 I can disable the search button but ideally I would want dialog to

 It presumably triggers a different code path that makes more/deeper

We're never going to agree, that much I can see.  My opinion is that
the user should be able to install anything they want (it's their
device) and if they end up installing something that was malware, it's
their own fault.  Do you gladly sit and click on the EXE files you
have coming to you?  Probably not, as you know better.

You want to protect users by not giving developers APIs.  I want to
give developers APIs and have the users protect themselves.

And that OS patch when it came out, iirc, was pushed out by the
carrier.  That means that people got it from a trusted source -- any
system and any OS could be compromised if a trusted source gives
someone malware.

[android-developers] Re: Free Version of App

[Streets Of Boston]

I get your point! Thanks!

You're checking a trial/free license and not a paid license.

And when they change phones, you don't lock them out of your app if
they don't buy it again. Instead, you give them again another trial-
period.

Let me get this straight :)
- Users download your free app.
  It checks the license, using IMEI, and this gives them a 30-days
trial amount.
- When the license says that trial has expired:
  - They don't get your paid version. And that's it. If they
move to a new phone, they get another trial! This is nice for the
customers.
Since customers don't change phones every month, it's not bad for
the
developer either.
  - They do get your paid version. If they move to new phone
they may as well download your paid app again, since they already
paid for it.


On Feb 26, 1:57 pm, Bob Kerns r...@acm.org wrote:
 I think in this situation, the IMEI is a better choice for identifying
 when a trial has expired. You'd like to let them try your app on their
 new fancy faster phone with the bigger screen!

 The ANDROID_ID is a better choice (if it really is tied to the account
 and not the phone?) if you're checking a paid license. But is there
 value in doing that? It would seem to simply duplicate the fact that
 they'd done the purchase in the market, and not provide any additional
 security.

 The IMEI approach works even for phones with no Market access, if
 you're looking to sell your app via other channels. Does the
 ANDROID_ID exist on devices even when there's no Marketplace?

  Aren't app downloads tied to a user's Google Checkout account. If the

  has to buy your app again. Shouldn't you use the 'ANDROID_ID' instead?-

It doesn't really do very much, just a wrapper around a buffer.

}

public static int allocate(int size) {
int r = _p;
_p += size;
if(_p  BUFFER_SIZE)
throw new RuntimeException(Dynamic buffer overflow);

return r;
}

// will only deallocate the last consecutive sequence of allocated
blocks
public static void deallocate(int size) {
_p -= size;
if(_p  0)
throw new RuntimeException(Dynamic buffer underflow);
}

// write to dynamic buffer at offset off (returned by allocate())
contents of buf at [buf_off,buf_off+buf_len)

  To clarify, in the original example, no buffer is allocated. The call

  So it is not a gc issue. Also, while the buffer might get filled with

Let me explain something.  Using directly allocated NIO buffers is a
DIRECT LINK between Java and native.  The pointer you get from (void

everything else.  This is one of the few cases where you can write to
natively accessible code that does not need to be copied to work on
like an array does.

It's not a copy.  It's the original buffer data that the native side
sees.  That memory will be freed when the Buffer's java object is GCed
(from no more references.)  It's safe to use that address so long as
you're still holding on to a reference to the Buffer (in Java, not
native.  That native pointer is only as good as the java
counterpart).  In the context of OpenGL, the memory is needed during
the GL bufferdata or GL array call and most likely during the draw
call (As that normally needs to read from system memory, particularly
with arrays) but I don't know if it needs it all the way to the end of
the flush.  One would have to ask why you'd be allocating/deallocating
memory in a real time simulation, though :)  Preallocation throughout
the sim would be the ideal solution and that wouldn't have issues with
invalidating memory before it's done being used.

In short, with launchMode=singleTask the behavior after re-visiting

(with a class name).  ASFAIK this is not documented. Not clear if it

[android-developers] Re: How to handle a cloned service from paid and free app?

[Streets Of Boston]

This is not optimal, but this is what i did.

Implement your service, aidl and related java classes in one of your
apps (either the free or the paid one) in your Android project. Make
sure that your service is up to snuff at some point and all runs well.
Be sure to put the aid and all related java classes under one package
name (or sub-packages). This makes it easier to move later.

Create a regular Java project. Use the android.sdk (instead of JDK1.5)
in the library path.
Physically move the package (and sub-packages) of your service code,
your aidl and your related java class, AND the java class generated
from your aidl, from your Android project to this new Java project.

Remove this package (and sub-packages) of your service code from your
Android project (including the java file generated by the aidl under
the 'gen' folder) if they are still there.

In your Android projects, both your paid and free version, link to the
newly created regular Java project that contains the code for your
service.

It works well for me.
However, if i need to make a change in the aidl, it won't re-generated
its java file, since it's no longer part of an Android project. That's
a downside.

In your Android projects subclass the class from your regular Java
project that is the Service. E.g. 'com.me.myapp.free.SomeService

[android-developers] Re: Developer Phone Number Listing

[Streets Of Boston]

You are required to hava a phone-number for your own checkout account.

But you are not required to put your phone-number on the Android
Market.
Go to your developer console, select your app and on the bottom, in
the 'Contact Information' remove your phone-number. Hit Save.

If customers still have your phone-number, maybe they get them from
market browsers such as cyrket and androlib. They got your number when
you first (and accidentally) listed it and they're slow to update your
changed market-info.
Or they just wrote down your number before you unlisted it.

 When I first started publishing Android apps as an indie developer, I
 posted my phone number on the app's submission page, thinking it would
 not be listed publicly. When I found out that it was, I removed the
 number from the app listing. I don't have the resources to handle
 phone support, and much prefer to handle support via email. Besides,
 there is no requirement that we provide phone support, as long as we
 provide support in some way, correct?

 Anyway, these days I'm getting fewer phone calls, but I'm still
 getting calls. We are required to list a phone number in our developer
 profile, but it is stated that this is used for Google to contact us
 directly in case there are issues.

 So where are users still getting my phone number, and how can I make
 sure it's not listed?

[android-developers] Re: How to handle a cloned service from paid and free app?

Hi St. of Boston!

That's great feedback!  It's really nice to know what other developers
are doing!  I'll look into that...

 This is not optimal, but this is what i did.

 Implement your service, aidl and related java classes in one of your
 apps (either the free or the paid one) in your Android project. Make
 sure that your service is up to snuff at some point and all runs well.
 Be sure to put the aid and all related java classes under one package
 name (or sub-packages). This makes it easier to move later.

 Create a regular Java project. Use the android.sdk (instead of JDK1.5)
 in the library path.
 Physically move the package (and sub-packages) of your service code,
 your aidl and your related java class, AND the java class generated
 from your aidl, from your Android project to this new Java project.

 Remove this package (and sub-packages) of your service code from your
 Android project (including the java file generated by the aidl under
 the 'gen' folder) if they are still there.

 In your Android projects, both your paid and free version, link to the
 newly created regular Java project that contains the code for your
 service.

 It works well for me.
 However, if i need to make a change in the aidl, it won't re-generated
 its java file, since it's no longer part of an Android project. That's
 a downside.

 In your Android projects subclass the class from your regular Java
 project that is the Service. E.g. 'com.me.myapp.free.SomeService
 extends MyService' and 'com.me.myapp.paid.SomeService extends
 MyService', where 'MyService' is now defined in your regular Java
 project. And put the SomeService in your Manifest.
