I don't think you are approaching this problem correctly...

1) Now when you say 'trace' I hope you don't mean method tracing, and
while that would allow you to put it in a specific file it is so
incredibly slow that the end user would hate you for it.

2) You can create an app to read the log file, I've seen at least one
in the market.

Can you use a service (free) like Flurry?  They allow you to do some
pretty cool stuff very easily.

Why exactly are you doing this 'for development only'?  If you're
doing it during development can't you just look at your own logs using
logcat?

 Hello everybody,

 I have used Android's log all around my app to trace some important
 events. As for development porpuse only, I would like to do one of the
 following things:

 1) redirect that log to a specific file in a SD-Card
 2) locate the log file, if already exist

 I both cases I will create another app that uploads the Log to a
 server, using FTP or something.

 Thanks very much,

 Kimi

[android-developers] Re: bug reporting

Certainly interesting but there are other solutions.

 1. It doesn't engage the user to acknowledge that a problem has occurred 
 (mea culpa).
Not true, you can pop up a message box in the default handler and tell
them an error occurred.

2.  It doesn't elicit contextual information from the user.
Again in the message you can ask them if they want the error sent to
your server.

3.  It doesn't help to provide the user visibility into the state of issues 
for the application (bugs nor enhancements).
Depending on how your app identifies the error you can tell them what
it is.  Also providing a change log in your app could be valuable.

4.  It requires that my application request internet permission
Well yes, most applications want this anyway (we are dealing with
smart phones here).  If you let the users know that it is for bug
reporting in the description they should be fine with it.

If the user doesn't choose to install it then I see that as an issue
because I won't know about the error, but yes then you are not
dependent on the internet permission in your standalone app.

Broadcast events would work to make it usable with several apps but
I'm not sure how much information you can stuff into a broadcast...
For example I would at least want a full stack trace and cause trace
from the exception that occurred, and this can easily be 20+ lines.

 So, I started looking at my options.  Obviously, if I hosted my source

 facility to report bugs.  On the off chance that a mobile user took
 the time to look up the project and submit a bug, I'd still be reliant
 on the submitter to supply correct and relevant diagnostic
 information.  I have my doubts that either would occur reliably.

 I came across this thread [http://groups.google.com/group/android-
 developers/browse_thread/thread/bae832439608ad2e/44d2e285da39aa57?
 lnk=gstq=exception+handler#44d2e285da39aa57] detailing a simple
 strategy for collecting information under the covers and posting an
 exception to a remote server.  I see some issues with this strategy as
 well:

 1.  It doesn't engage the user to acknowledge that a problem has
 occurred (mea culpa).
 2.  It doesn't elicit contextual information from the user.
 3.  It doesn't help to provide the user visibility into the state of
 issues for the application (bugs nor enhancements).
 4.  It requires that my application request internet permission.  If I
 wanted to allow the user to opt-in to send some personally
 identifiable information (say to support notification), then I'd need
 to request profile permissions.  I dislike jumbling together a lot of
 disparate concerns and then asking for every permission under the
 sun.  This trend will lead to users totally disregarding the
 permissions altogether.

 So, my thought was to implement a separate Bug Reporting application
 that handles bug tracking.  Other programs could elect to register
 with this app.  The BR app accepts crash information from a calling
 application, prompts the user to provide summary, description, and
 priority information, then posts the issue to the developer's bug
 server (indicated during registration).  The BR application could be
 further enhanced to retain these issue ids and allow the user to
 browse the state of them (by browsing to a well defined link or via
 some well-defined exchange with the bug server).  Similar
 functionality could be implemented to allow viewing change logs,
 release road maps, etc. for the app.  Obviously, the integration b/t
 the BR app and the client apps would be implemented in such a way that
 there would be a transparent no-op if the user decided to uninstall or
 never install the BR app (so as to not perpetuate a bad Vista-like
 user experience).

 It looks like I can license JIRA for $10 and open up anonymous issue
 creation.  So, far I've prototyped a simple BR activity and a JIRA
 plugin to accept BR submissions.  Obviously, the http protocol could
 be openly defined in such as way as to allow integration with any
 extensible bug tracking system.

 I'd like to hear opinions on this strategy.  Has it already been
 done?  Is it too intrusive or techy for users?  Do you agree or
 disagree that visibility is an issue?  Is there simply a better
 solution of which I'm unaware?  Ideally, such a thing would be
 embraced by Android

You should be able to use a relativelayout or a linearlayout and just

You're assuming things that are not true.  Its an activity stack, so

[android-developers] Custom Buttons containing layouts

2010-01-21 Thread theSmith

Hey all,

I was wondering if it was possible to use a RelativeLayout containing
TextViews as a button like object.  My goal here is to not have to
create 2 image button backgrounds (landscape and portrait), usually
this is not much of an issue but the buttons will span the entire
screen and the text will become distorted.

The RelativeLayout will contain 2 textviews and maybe an imageview
also (not sure yet).  So I'm looking to implement some button like
behavior, on focus, on click etc.  All I really need to do here is
modify the background color of the RelativeLayout.

Any pointers on where I should get started?

You could do this in one app if you have a minsdkversion of 1.6 and

[android-developers] Re: ATTENTION ANDROID TEAM: Take back control of Android.

2010-01-18 Thread theSmith

I believe that maxsdkversion has already been or is in the process of
being depreciated, meaning the market no longer looks at that tag in
the manifest.  Which makes sense because if the OS updated to a newer
version but not all the apps did, they would dissapear in the market
to that user, despite the fact that most would still work perfectly
fine.

 I agree with Mark that older apps, like 1.6 apps, run happily on
 newer sdks. Most apps can do without the newer features, if you accept
 that sometimes you have to do more work, or the feature you build is
 slightly less attractive. Or, you can have a Factory class that
 returns the right version class to use. As far as I have seen, you can
 have 2.1 classes in a 1.6 app, as long as you don't instantiate them.

By specifiying minSdkVersion and maxSdkVersion, you can provide
different versions for different sdks. Every user would only see one
version in the market, if I'm not mistaken. But you don't really want
to do that unless you really need those different versions.

[android-developers] Re: HashMap, ArrayList and fastest way to iterate Collections on Android (+other ways to make it run like a wild horse)

2010-01-17 Thread theSmith

Mika,

Check out the Real-time games and lightning talks videos, they're very
helpful.

As far as the speed, I would run some tests and look at the results,
some nice hard data :)
Become familiar with DDMS (the stand alone program, not plugin) - DDMS
has an allocation tracker, which lets you know where you are
requesting the most memory, which is what is going to slow you down.
http://developer.android.com/guide/developing/tools/ddms.html

Also you can use method tracing and traceview to further optimize your
code.
http://developer.android.com/guide/developing/tools/traceview.html

These tools are covered in some detail in the 'Debugging Arts of the
Ninja Masters' video

 Simple question, what is the fastest way to iterate through
 collections on Android? I generally use collection.iterator(); and the
 iterator.next() to iterate through the whole collection. Is it any
 faster to drop that and iterate with old (and I use the term old
 loosely...) :

 for( int i=0; icollection.size(); i++) ?

 I was thinking of getting the collection.size() into a separate
 variable so I wouldn't be asking the collection it's size all the time
 so basically the for loop would turn into something like this:

 int size = collection.size();
 for( int i=0; isize; i++ )
    collection.get(i);

 Any better? Speed wise, I mean. I'm in a point where I need to get
 every possible inch of speed for my application.
 Or maybe allocate everything into Lists in the start, and once I know
 the correct amount of data, I turn all that into arrays and drop the
 Lists so I can have array[index] (Log(1) access, right? OH wait.. how
 did this go again _ ) access instead of having the slow method
 calls in between like .get(); when accessing the data in the
 collection.

 And what about getters  setters for Classes? Like let's have a
 Vector2D class that contains obvious integer x and integer y values.
 What is the fastest way to access them inside the class? Have them as
 public and just straight Vector2D.x = someValue; or through getters
 and setters? I've had much debate with my tutor about this (working on
 my final year project) but not to get too much into details of it...

 Also all links for further Android application optimisation are more
 than welcome and greatly appreciated (I read the googles docs on this
 already). Plus if you have found some really good tricks / quirks on
 Android to punish the device even more so it runs faster, do share, do
 share. Heh.

 Please be gentle on me, I'm such a beginner in all things Android that
 I feel absolutely dumb as a boot for asking these kind of things. I
 come from strong C++ / Java background but getting the extra inch of
 speed for everything on Android is so different than optimizing code
 for PC side and not that you even have to do it on PC side that often.

provide us with copy protection that works...)

For those interested here is another site I found yesterday,

 I believe I've already answered the question of why Google would do
 something about this, but I'll say it again. Piracy damages the
 platform as a whole. Google cares about this kind of thing because it
 slows the progress of the platform as a whole. That's why they
 released the Nexus One --  to advance the platform by gaining new
 developers and users.

 I'd be surprised if Google did not have people working on this. But my
 specific inquiry is who can I talk to about this? who or where do I
 report this? And if it does not yet exist, Google should definitely
 set up a system for reporting these abuses.

 On another note, I think the common attitude of apathy surrounding
 this issue is shocking. I am fully aware that it's not possible within
 reason to completely eliminate this problem -- and I do not expect
 that. However that does not mean we should ignore the issue on the
 premise that its too difficult a problem to deal with.

 This is especially problematic for small time developers who don't
 have the resources (time or financial) to do much about this. I
 believe it's these small time developers who provide the most value to
 the platform -- there are far more small time developers than large
 organizations, and I believe they provide the bulk of the innovation.
 So lack of a robust support system for these developers is a big
 problem.

 I'd like to steer the discussion in a more positive direction. So lets
 go guys -- resources, information, options...

If you need multiple hit areas you may want to consider using several

This approach will most likely save you quite a headache.

[android-developers] Re: Updating a unique AppWidgetProvider from a Service

2010-01-14 Thread theSmith

No problem, heres how I did it.

AppWidgetManager manager = AppWidgetManager.getInstance(this);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.widgetlayout);
views.setTextViewText(R.id.TextView_Body, hello world);
appWidgetManager.updateAppWidget(appWidgetId, views);

onHandleIntent is called every time you use context.startService
(intent);  Just make sure to use that intent to send the appWidgetId
you need updated.  If the IntentService is not already running then
its onCreate() is called, other wise the intent is put into a FIFO
queue.  the onHandleIntent method runs on a seperate thread than the
rest of the app, even the IntentService's onCreate().  This allows you
to do time consuming processes like networking without android giving
the user a ANR dialog.

If you want to probe my brain some more feel free to ask.

[android-developers] Re: One service to rule them all

If you are writing the applications (or otherwise over seeing it) it
is not hard have communication between applications, you just have to
read up on intent filters for the application's manifest.xml

Correct me if Im wrong, but you should be able to create an
application that checks if the other applications in the suite are
installed, which version they are etc...  This app could also notify
you of updates to existing applications and new applications.

On your central server you can check the applications version number
and refuse the connection if it is not up to date, then prompt the
user to install the newest version.  (either through the market or
straight from the server.  The browser sends .apk downloads to the
application manager if I remember correctly)

 That depends a lot on the suite of applications. If you wrote that

 In general, yes. In a secure fashion, not easily.

  Would it have to restart itself?

 Probably not. You would need to download JARs or scripts (e.g., JRuby,
 Beanshell) as your plugins, and you can probably find ways to reload
 those on the fly (e.g., use your own classloader for the JARs).

 You can't have a plugin architecture based on APKs very easily -- see my

[android-developers] Re: EditText.getText() not working

using findViewById() 81 times seems more demanding than creating them
at runtime to me.

There is always an Exception thrown if your app is crashing, look at
the logcat in the 'DDMS' view in Eclipse.
If you only see a runtime exception then you need to get the cause
from the exception. Surround the call with a try-catch and use
something like this:

catch (Exception e)
{
   final static String TAG = you app name;
   StackTraceElement[] arr = e.getStackTrace();

   for (int i=0; iarr.length; i++)
   {
   Log.e(TAG,arr[i].toString());
   }
Throwable cause = e.getCause();
 if(cause != null) {
 Log.e(TAG,Cause: +e.toString());
 arr = cause.getStackTrace();
 for (int i=0; iarr.length; i++)
 {
Log.e(TAG,arr[i].toString());
 }

 }

[android-developers] Re: Marketplace

If you have sync turned off, the market will ask you to 'enable
background data usage' Then takes you to the Data synchronization,
background data setting.

My guess is that it sends a list of applications that you have
installed with their version numbers, which is how it can tell if they
need to be updated.  But like I said, this is all just me speculating.

If the CheckBox is inside an AdapterViewCheckBox then you can cast

So what you are saying is that Android development doesn't really want
developers building applications that use Flash?

Only a few phones have Flash at this point so, no, I would not suggest
using it.

Longer term... well, it would be problematic for this to become a standard
part of the Android SDK. Given that flash is proprietary, that would leave
us with the platform becoming dependent on someone else's proprietary code
in order to support these apps. This is very counter to a basic philosophy
of Android, that the entire platform is open-source and thus you don't need
to someone's proprietary code to build an android compatible device.

(And to head off the inevitable cries about not really being open-source --
yes there are bits and pieces that are not open source, such as hardware
drivers and applications like Market. This is a far cry from baking
dependencies on non-open-source code into the standard APIs, though.)

But it now sounds like if anyone wants to develop an Android app that uses
Flash it'll be more of a gamble and might not work for most devices or at
the least be a hassle for the end user to make it work because they would
have to install Flash plugins.

I can't tell you what devices Flash may or may not be available on, because
it is owned by Adobe. Clearly they have a self-interest in getting it as
widely spread as possible, but from the perspective of the platform we can't
make any guarantees about who can include it on a device, the kinds of
hardware it can run on, and how well it would perform. And that is one of
the big rubs.

It is kind of disappointing because if Android and Adobe can get together
and start supporting development of applications that use Flash then that
would be an Ace in the hole for making Android apps far better than the
IPhone.

The first step for having some technology adopted for the standard Android
platform is to make it available under an open-source license that is
compatible with the rest of the platform. Somehow, I don't see this
happening for Flash. :}

To follow up on my own question, heres how I did it.

I went from a service to an IntentService and in the onHandleIntent
(Intent intent) I handle the update requests.

To get the individual id's I put them as an extra in the intent in the
onRecieve() method in the widget, then fire them off to the
IntentService with context.startService(i).  Everything is working
perfectly now.

You might also want to run a method trace around your network activity
to see where the most processing time is spent. The results you get
wont be in actual time, but a relative time just because method
tracing is slow.

Just wrap you code with a start and stop calls, and make sure to have
the writing to external storage permission in your manifest.

// start tracing to /sdcard/calc.trace
Debug.startMethodTracing(calc);
// ...
// stop tracing
Debug.stopMethodTracing();

If you're doing frequent requests, you can probably take advantage of

If you're looking for optimizations, I strongly suggest you create a test
app which performs the same request you're having performance problems with.
Collect more data, such as the size of the request and response. Try the

Compare the network paths between the desktop and Android to the server.

[android-developers] Re: How can i stop a thread in a Activity?

That would work also, you just have to remember that function calls
are never free and the GC on android is annoying enough as it is, no
need to give it more stuff to do.

  I ended up using a shared volatile variable that is check when I'm

   Calling interrupt() only works if your thread is interruptable and if

   Your thread only is interrupted if the thread is doing I/O or is in a
   wait-state (having called wait() on Object).

   If you want to have background threads that do one-shot jobs and then
   wait, use AsyncTask or the java.util.concurrent's ExecutorService .

   And, you'd better read up on concurrent programming a little :-) It
   can be tricky.

Try storing the newly spawned thread as a field or collection in the

 My problem is:
 Activity A called Activity B, and in Activity B, it start a background
 thread to do some client-server work. But it maybe takes too much
 time. So i add a cancel button to call the stop() method to stop the
 thread, and call finish() to finish the Activity B and go back to
 Activity A. Although it is back to Activity A, the thread isn't stop
 immediately.

 Can i just call the finish() to go back to Activity A, and leave the
 thread to exit by itself?

 That's pretty much the point of having them ...

I agree, just take what ever action is necessary and put it in the
onClick listeners.  Its really that simple

[android-developers] Re: How to hack the activity stack of your application ?

If you want to, you can override the onDestroy() method of the service
and have it call finish() on each of you activities in the stack.
This should result in the behavior you are looking for I believe,
because the system would be forced to create a new instance of your
application, thus starting a new service with it.

 Hi all,

 Differently from most application, the state of my application is not
 controlled by its stack of activities but by the state of a background
 service.

 Here is my problem. Suppose I have a task running  with  a non empty
 stack of activities. The top activity is paused on background and not
 visible.  Then for some reason the  process that host both the service
 and top activity is killed.  When I somehow return to my app
 application ( by pressing back key, resumimg from recent apps menu),
 the framework launches  the application again with the activity that
 was on the top of the activity stack  before process got killed.

 Okay, you would say that it is the expected behavior. But because my
 service is no longer alive , the top activity is no longer valid ( as
 the other activities which remain  on stack) . I would like to clear
 the whole activity stack  and launch another activity to explain the
 current situation to user.

 I could put the follow code on every activity if(not valid state)
 finish() and launch a new activity with clear top flag  enabled  but
 I don't think it is clever.  Is there a better way to control which
 activity will be launched after application is killed ?

 Tks,
 André

[android-developers] Re: No Adobe Flash support for Eclair!?!

As Mark said, unless you have a Hero, which has flash built it, this
will not work.

Thank you Mark for the clarification it is greatly appreciated.
With so many different sources on the internet it is somewhat difficult to
know what is actually available and what isn't.

One more question if you happen to know this. All I am simply trying to do
is create a WebView (using android.webkit.Webview) and view a .swf file with
it.

According to this article it is had been done and is
possible:http://www.flashmobileblog.com/2009/08/12/flash-development-with-andr...

But again like I stated before, after downloading the latest source code,
building it, flashing it to my development phone and flash still not working
I am having my doubts (and greatly wondering how this guy said it is
working).

Do you know if this is even somewhat possible (maybe a FlashLite plugin I am
missing or something?).

Or am just out of luck on this one.

Thank you

1. Eclair came out in 2009.

2. AFAIK, nowhere credible was it written that Eclair would have support
for Flash 10 built into it.

This does not appear to be the case for the fact that I download all
the latest source code for Eclair, built and installed Eclair onto my
development phone over the Christmas break and to my surprise/
disappointment there is absolutely no support for Flash when I try to
view with the browser. I tried plugin's and searching for missing .apk
installs for Flash but I found nothing.

Flash is not open source.

Right now, the most that can reasonably be expected is for Flash to be
available from Adobe for Android OEMs to license and put on their
devices. HTC has already done this with the Hero, albeit for more of a
Flash Lite profile than a full Flash 10 implementation. This is not
significantly different than codecs for non-open-source media file
formats (e.g., WMA, WMV) being available for OEMs to license from
PacketVideo.

[android-developers] Re: Droid 2.1?

Not to burst your bubble, but my apps have seen the Google Nexus One
and 2.1 for about a month now (found them looking through my Flurry
stats).

As for the Droid build part, well I guess we we're all expecting it to
come eventually.  Any one heard of an official release date?

None that I've heard of, but you can always buy a cheap G1 and root it
if you want to. (root access is the only advantage of having a dev
