 Topic: Which Intent flag should I use?

Zsolt Vasvari <zvasvari@gmail.com> Dec 31 10:26PM -0800 ^

 
This is part of my ongoing effort to tidy up my AppWidget code:
 
When a user clicks on my Widget, it goes to an Activity "deep" in my
app. When the user finishes this activity, I'd like to exit back to
the Launcher as opposed to whatever the last Activity on the stack is
for my app.
 
Is there an Intent flag I am not using correctly? I tried all the
ones I could see to be relevant, but nothing worked. I know I could
probably pass result codes back up the stack to wind down my app, but
that's some ugly stuff. Is there an easier way?
 
Happy New Year everyone!


 

 Topic: Database Database Database

Abhishek Talwar <r.o.b.i.n.abhishek@gmail.com> Dec 31 10:00PM -0800 ^

 
Hey guys
I have simple 2 button screen which are "Create Item" and "List'
These two have been linked to other activities with intent.
Now in create.java class i have 2 fields name and description and a
save button.
So that when the user clicks save button the data must get saved but
it is giving me a force close error.
 
This is my error message

 Topic: Virtual screen size

Pedro Duque <pmduque@gmail.com> Jan 01 02:05AM ^

 
When developing a live wallpaper how can I get the virtual screen size? How
can I know in which virtual screen the user is in?
 
Thanks,
PMD


 

Pedro Duque <pmduque@gmail.com> Jan 01 05:42AM ^

 
Let me develop on this subject:
 
I've develop a Live Wallpaper that was working perfectly in Android 2.1. It
emulate the standard Android wallpaper by having a bitmap scrolling when a
user changes screen.
 
To achieve that effect I use the event "onOffsetsChanged" to detect screen
changes when the user swipes left and right.
 
I just installed Android 2.2.1 and now the values returned in onOffsetsChanged
for xPixelOffset and yPixelOffset are always 0. The value for xOffset
and yOffset
do return values from 0 to 1 but because
WallpaperManager.getInstance(myContext).getDesiredMinimumHeight() and
WallpaperManager.getInstance(myContext).getDesiredMinimumHeight() now return
the screen physical size instead of the screen virtual size, I have now way
to calculate how much that percentage represent in terms of actual
displacement.
 
I know it's possible to achieve the desired result because the packed
wallpaper has that behaviour.
 
Can somebody help? Is this a problem with Samsung Galaxy S implementation or
is this a standard behaviour?
 
Thanks,
Pedro Duque

 Topic: Licensing Verification Library and Demo versions

John Lussmyer <johnlussmyer@gmail.com> Dec 31 07:01PM -0800 ^

 
Is there a relatively easy/good way to have an app that uses LVL, also have
a Demo version?
It appears that I have to change the Package Name to do this - which changes
the Resource file name - so nothing compiles unless I go change the import
statement in all my files.
Note that I am working from within Eclipse.
 
Should I make my entire app an Android Library? and just have 2 nearly
empty skeleton projects to build it? (Free and Paid versions)

By default, yes. It will just try to expand the columns to fit it's
contents. Try using weights and the shrinkable / expandable properties to
control the column widths.

There's rarely good reason to deal directly with screen measurements.

 Topic: app security

Bob Kerns <rwk@acm.org> Dec 31 06:44PM -0800 ^

 
This isn't really an Android issue. Anyone who gives out credentials
for any purpose needs to consider that they may be compromised.
 
The usual ways of dealing with it are to time-limit them, and to allow
them to be revoked.
 
But what I think REALLY should be done, is to issue credentials with
two components, one revocable by the issuer, and one revocable by the
recipient.
 
So, on losing your phone, you go to a website, and invalidate all the
credentials that were associated with the phone.
 
This wouldn't deny you access, just force you to go through the re-
credentialing process for each affected entity, using a reissued
token.
 
You could see extending this to three components, so a company with
accounts with Salesforce.com and similar things, could revoke access
for a terminated employee, for example. In this case, the access token
would not be reissued.

Excellent! There's no question it's hard work, and there's no doubt it
does compete with this or that feature.
 
But I'm confident it will pay off in quality -- and quality, in the
end, saves you time.

 Topic: Issue with messages in this group?

Bob Kerns <rwk@acm.org> Dec 31 06:25PM -0800 ^

 
HOW do you know you're not crazy? I'm missing a step in the logic
here... :=)
 
Seriously, it's really a shame Google uses what I'd argue is their
worst product to support Android this way.
 
It's too bad this isn't a Wave, perhaps Wave would have gained some
traction. (Though I suspect it wouldn't have scaled to this sort of
usage).
 
But most any forum software would be superior to this.

Happy New Year TreKing :)
 
Right, I did try using table but the column will be stretch if the
text is longer than the image.
Is it suppose to work this way? or it is possible to wrap the longer
text to 2nd line?
 
I am now thinking whether there are ways to dynamically take the

 Topic: using getSurfaceFrame to get display width/height?

Daniel Quach <dan.a.quach@gmail.com> Dec 31 03:51PM -0800 ^

 
So I'm trying out making a live wallpaper and I'm using the sample
code provided in the SDK for the cube live wallpaper
 
I wanted to use this code to get the height/width of the display
 
 
@Override
public void onCreate(SurfaceHolder surfaceHolder) {
super.onCreate(surfaceHolder);
 
Rect frame = getSurfaceHolder().getSurfaceFrame();
float width = frame.width();
float height = frame.height();
// By default, we don't get touch events, so enable them.
setTouchEventsEnabled(true);
}
 
Unfortunately, when I run this code, the width and height return as 0,
though if I put this in onVisibilityChanged, the correct values are
returned, why is this and is it suitable to move the code to
onVisibilityChanged?

 Topic: making Toast like notification?

Emmanuel <emmanuel.astier@gmail.com> Dec 31 11:06AM -0800 ^

 
I did make a blog entry on the toast customisation subject :
http://androidblogger.blogspot.com/2009/10/tutorial-how-to-customize-your-toasts.html
So you can modify the look of the toast !
 
But I do agree with you that the toast is not fulfilling all of our
needs, I also though about reimplementing something like a toast.
Actually the bigger issue I have with the current toast is that you
can't control acurately the amount of time it is shown, and you can't
discard them.
 
I used them in my "Word Prospector" game to give feedback to the
player when they are doing right or wrong, and if the player tends to
play very fast, the toasts accumulate, and are shown out of the
correct context : ie the feedback is not fired for the latest player
action. They can even be fired when the player is no more in the game.

I will just have to avoid this and using the notification bar then...


 

 Topic: the new eclipse UI design - absolute frustration and waste of time

Bob Kerns <rwk@acm.org> Dec 31 12:52PM -0800 ^

 
Actually, I find the huge properties menu to be an improvement over
the old properties view (which is still available, BTW).
 
The "Attributes you can't seem to control" thing is definitely a
problem.
 
For example, with a relative layout, depositing an item to be "below"
another, you can't just get "below", you also get one or both sides
aligned. But what I really want is to align the side to the parent
view. I haven't found any way to do that. You can't get "below" alone,
and once it's attached to the one above, you can't attach it to the
parent without losing the connection to the one above.
 
I do find it saves time in the very initial setup of a screen, or if
I'm just tweaking a property here or there. But at the moment, if I
try to do more than a limited set of things with it, I end up wasting
my time.
 
I do think it's going in the right direction -- and I look forward to
its arrival!
 


 

Julian <cacifali@gmail.com> Dec 31 04:29PM -0500 ^

 
I think the adt is going backwards, the GUI designer is a waste of time,
drag and drop just does not work properly, we just need the up and down

AsyncTask can be carried through configuration changes by using

The technique was discussed on this list within the last month or two,

 Topic: Cannot compile Desk Alarm Clock (branch eclair ver 2.1)

Anil Philip <anil.rita@gmail.com> Dec 31 02:07PM -0600 ^

 
Alright, I created an ubuntu partition, installed git, repo, eclipse,
downloaded the eclair branch of android and built it.
Created a Java project using 'existing src' with the android root directory.
Was wondering how I should run/step through the Desk Clock application.
Since there is no ADT plugin, If I "Run as Java Application" it simply
brings up a list of internal and library modules like Svc, Command shell...
Should I run the emulator in the debugger and then click on the alarm clock
app? (Debugging the emulator with Eclipse

Crappy Android has been improving over the last year as work has been done
to update the various apps to use various final SDK APIs that weren't
available when they were first written.
 
This is often a fair amount of work, and means desired features or bug fixes
can't be done, so sometimes it is slow going.
 
If it is something you feel strongly about, many app developers would
probably be happy to review contributions.
 
Btw you can determine if an app is building against the public SDK by
looking for LOCAL_SDK_VERSION in its Android.mk. A quick scan of
Gingerbread shows that these app build against the public SDK:
 
Calculator, Camera, DeskClock, Gallery3D, Mms, Music, Protips,
QuickSearchBox, Tag, and LatinIME.
 
For the original poster -- DeskClock is the new AlarmClock. The AlarmClock
code has not been used since at least 2.2.

 Topic: Memory Leak in 1.6

John Gaby <jgaby@gabysoft.com> Dec 31 11:32AM -0800 ^

 
I seem to have a memory leak when running under version 1.6 of the
OS. I have a custom view group which contains some controls and I set
it to be the current view via a call to setContentView(vg). If I then
create a second view group and set it as the active view via
setContentView(newVg), the first view group is never freed (even when
I force a garbage collection).
 
Note that this works fine for versions 2.0 and above, so it is
possible that 1.6 has some kind of bug. If so, does anyone know of a
workaround? I can post a simple example of this problem if it would
help.
 
Thanks.

I don't know, but if you're trying to save an image to a file, you might as
well make sure you have a reasonable extension for the file type. Probably
won't make a different, but who knows.

Is is very interesting that intent doesn't return any path or similar for
picture that is taken.
There is no info ,and believe me I've searched for , that feature like that
exists.
Of all the things I think getting path of taken picture whould be most
useful.

Once the Nexus S USB connection stopped working, I have not been able
to revive it. I have tried
 
- rebooting my laptop (running Vista),
- performing a Factory reset on the Nexus S,
- uninstalling and installing the Google USB driver (version 4.0), and
- fiddling with Nexus S Settings that have anything to do with USB
(i.e., "USB debugging", "Erase USB storage", "USB tethering").
 
My Nexus One USB connection continues to work with the same laptop.

 Topic: Screen Rotation

Robert <rcopelan@gmail.com> Dec 31 09:48AM -0800 ^

 
I have an application that I am trying to stop the automatic restart
when the screen is rotated. I put android:configChanges="orientation|
keyboardHidden" into the Manifest (copied below) but the screen still
rotates and the OnCreate is called (verified by writing to the log in
OnCreate). Have I missed something else that is required to stop
this default action?
 
The reason I want to do this is that the app is accessing a webserver
via an AsyncTask and I'd like to stop the restart until I can figure
out how to link the background task to the new pid that is created.
I've read some pages on it but not yet clear how to do that.
 
Sorry for maybe some terminology that isn't correct. Hopefully the
issue is clear though. Thanks for any pointers to information that
may help.

Quoting the docs for that property:
 
*Note:* Using this attribute should be avoided and used only as a
last-resort. Please read Handling Runtime
Changes<http://developer.android.com/guide/topics/resources/runtime-changes.html>
for
more information about how to properly handle a restart due to a
configuration change.
 
I highly recommend you spend the time figuring out how to do this correctly
then wasting time on a hack that will cause other problems.

 Topic: the new eclipse UI design - absolute frustration and waste of time

John Lussmyer <johnlussmyer@gmail.com> Dec 31 08:23AM -0800 ^

 
I've used the NetBeans and MyEclipse GUI editors extensively. They are very
nice.
The Android thing in Eclipse is pretty much a waste of time. Bizarre things
happen when you try to drag controls or layouts in. Items end up in totally
unexpected places, with attributes that you can't seem to control. The huge
properties menu isn't very helpful either.
 
After just a few minutes of attempting to use the GUI editor, I gave up and
just edited the XML directly. Much easier, quicker, and with better control
of what you get. I don't even bother previewing my layouts with the GUI
editor, as it frequently leaves out controls entirely.

 Topic: Large Icon not showing up in Market Display

JRock <developer@earthblood.com> Dec 31 08:09AM -0800 ^

 
The recent market application changes now show a large icon for your
app in the upper left hand side of the screen when viewing the app's
listing....for my app, however, it is still showing the tiny icon in
the middle of a huge white rectangle.
 
From the Developer console I have uploaded the new entry for a high
resolution icon of 512 X 512 dimensions, and I assume that this is the
icon that is supposed to be showing, yet, as I mentioned, it is not.
I have no idea what the 512 X 512 Icon is used for if not to display
in the market listing.
 
Does anyone know what is going on here? How do I make the proper sized
icon appear in the market display?
 
Thanks for your help.

It's not and I don't think anyone knows what it's for.

You need to upload an image to the *Promotional Graphic* section.
 
Why the Promotional Graphics that is now used in the new Market is NOT
required, but this random, unexplained 512X512 icon IS required, is beyond
me. Android Market Interns strike again!

The likelihood of finding code examples that perfectly solve the particular
layout problem you are having at any given time is pretty much zero.
 
 
However, this is a pretty simple layout. Looks a like a two-row, two-column
table, with each cell containing a centered vertical linear layout with an
image and text. Then play with the padding and margins until it meets your
needs.

I am not keen on testing 1.5 and such "sort of" tests usually are a

Certainly there must be a means of finding and deleting this data?
I've been told it goes onto the SD card, but I see it nowhere for

I have many TextViews with a lot of text that causes them to wrap and they
always wrap around the words (as in your second example).
Is that all you're doing? Just setting text and it shows up that way?
Weirdness.

 Topic: How to read file from assets dir?

Bob Kerns <rwk@acm.org> Dec 31 07:03AM -0800 ^

 
Can I suggest adding links (perhaps not real hyperlinks, but
conceptual links at least) from the API documentation to the relevant
API examples?
 
I think you'd get a lot more value from the work you put into the API
demos this way.
 
Also, I'd concur with the recent comment, but not the tone, that a lot
of the API demo classes are quite poorly named. Even if you know that
there IS an API demo for what you want to find, it can quite difficult
to locate it.
 
Think of it as, the API demos could use a bit more product marketing
to get them to their intended audience. :=)
 


 

 Topic: the new eclipse UI design - absolute frustration and waste of time

Bob Kerns <rwk@acm.org> Dec 31 06:55AM -0800 ^

 
Just to clarify -- I'm NOT saying the current state doesn't have huge
usability problems! (And so did the previous state).
 
I'm only disagreeing with the sentiment that "real programmers only
want to use the XML, and ignore the GUI". Even now, when it works
right (and I can figure out how to use it), it's a time savings.
 
When it's not, I end up reformatting and fixing the XML.
 
My point is, it's quite worth the Android teams' time improving this.
It's NOT just newbies who don't understand the XML who will benefit.
 
In fact, I think it would be a good goal to make the UI expose the
functionality so clearly, usably, completely, and unambiguously that
knowing the XML offers no benefit to the "real" developer (unless
you're writing automated transformations on it).
 


 

 Topic: Google analytics crash

H <me@howardb.com> Dec 31 05:26AM -0800 ^

 
You could stick a try/catch block in, but I doubt it would catch *most* of
the bugs. Remember that your request for a track simply gets added to the
database at that point and then some time later the dispatcher picks
requests up from the database and sends them (although if you ask it to
dispatch immediately you might catch them, but due to the use of handlers, I
still doubt it). So your try/catch in your code would only catch errors from
the first part and not the second.
 
From the ACRA reporting in my app for the previous release of the analytics,
the vast majority of my errors were coming from the latter part of the
process where it was trying to read back from the database or failed during
the sending part or failed when removing entries from the database.
 
The analytics team did state they fixed a load of bugs in this latest
release. I don't know if it's against the rules or not, but I decompiled the
latest release and built it natively into my app and that allowed me to
stick in a sprinkling of my own try/catch clauses around spots that I
thought looked tetchy. I haven't released this yet..


 

blindfold <seeingwithsound@gmail.com> Dec 31 06:14AM -0800 ^

 
You may be right, although the crash reports that I have all suggest
that they were triggered from direct calls to
GoogleAnalyticsTracker.trackEvent() in my code leading to
"java.lang.IllegalStateException: no transaction pending". Judiciously
sprinkling try-catch blocks is a great way to further "uglify" source
code, so maybe I'll just live with the occasional crashes until Google
fixes the problem, given that thus far only 3 out of 5000 app runs
gave me crashes.
 
Thanks
 
 


 

H <me@howardb.com> Dec 31 06:21AM -0800 ^

 
Looking in the analytics source after you've called trackEvent(), I suspect
that error is coming out when it is using a database transaction to insert
the event into the database. Once inserted, it calls endTransaction as well
as setTransactionSuccessful. Both of these do this check:
 
if (!mLock.isHeldByCurrentThread()) {
throw new IllegalStateException("no transaction pending");
}
 
So it could be worth checking to see if you are tracking the event from a
thread that has ended, or calling dispatch from a different thread...?
 
HTH.


 

blindfold <seeingwithsound@gmail.com> Dec 31 06:55AM -0800 ^

 
Hmm, I have only one global tracker object that I create in the
onCreate() of my main activity, and with a regular dispatch interval
through the format tracker.start("UA-12345-0", nseconds, this), so I'd
say that it all works from one alive thread. However, in one pair of
crash logs the first GoogleAnalyticsTracker.trackEvent() crash occurs
after my app had been running for some time, while the second
GoogleAnalyticsTracker.trackEvent() crash occurs immediately at app
startup only 3 minutes later, for the same device FINGERPRINT,
suggesting that indeed some sort of lock had lived on even across runs
to cause a second crash because the second run would not be owning the
lingering lock. This was for a Samsung GT-I5800 running Android 2.1-
update1.

I've read lots of posts to resolve this problem but couldn't find its

couldn't resolve my problem.
 
In my manifest file, I've used
android:windowSoftInputMode="stateVisible|adjustResize" for
ListActivity as well.
 
You help is much appreciated!!
 
Thanks!


 

Federico Paolinelli <fedepaol@gmail.com> Dec 31 06:50AM -0800 ^

 
Having your view wrapped into a scroll view should make the trick.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">
 
</ScrollView>
 
To be honest, I never tried it with a listview, but it worked quite
well with my text + edit text views.
 
Hope this helps,
 
 
Federico

Is this the right way to write my service? How would I verify my
service?

No. Use AlarmManager.

Test it?

This is error-prone, since a service can get kicked out of memory at any
time, and all threads (including the thread used by Java timers) will
terminate.
 
Set an Alarm with AlarmManager, it avoids the issues caused by
interference from process lifecycles:

Hi All,
 
Is it possible to write a JNI to access GPS / Wifi / USB HAL layer
function? If possible, please post the sample code.
 
 
 
Thanks

 Topic: Best way to resize photo

Doug Gordon <gordonwd@gmail.com> Dec 31 09:02AM -0500 ^

 
Among other things, my app displays photos in an ImageView in a popup
Dialog. These images come out of a database that is created on the
user's PC. Before storing them in the database, I resize them for max
dimensions of 320x320 pixels.
 
So, in almost all cases, on the Android device I simply display the
photos at their "natural" dimension, which fits nicely on almost all
screens. However, I have at least one customer with an HTC Wildfire
which, even though its screen is 3.2", has only QVGA dimensions
(240x320). With my current code, the photos do seem to be resized by the
system to display within the screen boundaries, but the rest of the
views in the dialog (caption, buttons, etc.) get "pushed off the screen"
and are not visible or usable.
 
Obviously I need to handle this case by setting some specific dimensions
on the ImageView when running on a QVGA device, but what is the best
approach? Should I use DisplayMetrics to discover the dimensions and
adjust accordingly? This would work, but seems like it might be too
low-level of an approach. Could I put dimension the image in the XML in
some way using "dips"?
 
(By the way, it's interesting that Android considers this class of
display to be a "small screen" for Manifest purposes, but at 3.2" it's
not physically all that smaller than a lot of other devices with higher
res.)

I was looking at that but didn't want to say anything so I don't spoil open
mind spirit :)
 
Because android still has many problems and I would like this simple action
to work on most phones I wanted
expirienced answer.
 
Thanks for your help.
 
 
PS: FORTRAN is ok for android.... you aren't using Java right? :)

Its a webservcie which uses OAuth. For OAuth in Anroid, use this:
http://code.google.com/p/oauth-signpost/
 
 
Here is an article on using OAuth in Android.
http://donpark.org/blog/2009/01/24/android-client-side-oauth
 
Read Yahoo contacts API documentation:
http://developer.yahoo.com/social/rest_api_guide/contact_api.html
 
 
May be you can find some complete Android code example in the web, try
searching.
 
And, finally, try to start coding, if you stuck, post in groups for help. Do
not expect complete code sample in a group before starting.

If the crux of your problem is using the Yahoo API, you should ask your
question on a forum dedicated to the Yahoo API.
 
If the crux of your problem is specifically related to Android, please
elaborate what Android-specific problem you are having.
