[Dianne Hackborn]

Long press is a back-door for the user to bring up the keyboard outside of
the app's control.  It isn't really intended to be turned off.

[android-developers] Re: Cannot write SharedPreferences after update!! Help!

[Sheado]

Hello again..

I have more details about this problem.. perhaps somebody can help
clarify things now =)

So if I test by installing and upgrading via the browser only instead
of the browser/market combination then things work out ok - I don't
get the mismatched uid error:
com.my.application.package.path has mismatched uid: 10031 on disk,
10046 in settings; read messages:

Another thing I forgot to mention is that I'm using copy-protection in
the market - could this affect how uid's are generated? Speaking of
which, how are uid's generated - are we (as developers) supposed to
know or care at this layer of abstraction?

And one last question! If all upgrades are performed exclusively
through the market (with copy protection) will I have to worry about
all this uid business?

help! thanks!
Chad

[android-developers] change key width runtime

[Long]

Hi,
  I want to change the key width in keyboard at runtime.
  The constructor of class Keyboard only accepts the layout resource
ID.
  I tried setHeight method, but it didn't work obviously when I
checked the code of Keyboard.

  Any solution? Do I have to implement my own Keyboard

Thanks a lot

[android-developers] Correct use of Task Affinities and LaunchModes

[Gavin Bong]

My android app contains a suite of mini apps. In short, every screen
contains a navbar with several clickable icons, one each for the mini
apps (and one for the Main screen). When an icon is clicked, the mini
app is launched. In total I have 4 mini apps. So you could imagine
that my main screen is like the Home Screen Launcher. Although these
mini apps could run standalone by their own, I want the user to be
authenticated. Thus there is a LoginActivity right before the
MainActivity.

LoginActivity ---> MainActivity ---> AppOneActivity or AppTwoActivity
or AppThreeActivity or AppFourActivity (aka PresenceListActivity)

I'm still not pretty sure of the benefit of Tasks (arranged set of
Activities), so I would like comments from Android experts on my
design decisions:-

(1) I plan to set the attribute finishOnTaskLaunch to true for
LoginActivity. As I understand it, once the login is authenticated, I
will navigate the user to MainActivity, and I want LoginActivity to
disappear. Is this better than calling #finish on the Activity ? Will
MainActivity automatically become the root of the Task without any
extra configuration/code ?

(2) One of the mini app is an IM client. The PresenceListActivity will
hosts many instances of ChatActivity (one-to-one chat session with an
active contact in the buddylist). I plan to use the default launchmode
for ChatActivity since each Chat should be handled by a new instance.
Sounds correct ?

(3) As for the sticky navbar, I plan to set the clearTaskOnLaunch
attribute to true for all of them. As I understand it, that should
clear the stack whenever I plan to launch into any of the mini apps.
Also their launchModes will be singleTask. Am I on the right path ?

(4) Finally I don't really understand how to read the output of adb
shell dumpsys activity. For example

Task{10 com.me.rnd.exit}
clearOnBackground=false numActivities=1
affinity=com.me.rnd.exit
lastActiveTime=5513102 (inactive for 5s)
  History #1: .

Task{2 com.android.launcher}
clearOnBackground=true numActivities=1 rootWasReset=true
affinity=com.android.launcher
lastActiveTime=5512949 (inactive for 6s)
  Running #0:
Sometimes underneath the Tasks, you will see History and in others
Running, what do these mean ? Even stranger, sometimes I have two
History under a task.

Thanks

[android-developers] Re: Build APK file from command line...

[HandsomeboyIT]

Thanks Xavier,
I use these command

>> apkbuilder.bat %FILE_NAME% -u -rf  "./project_folder"

then

>> keytool -genkey -v -keystore "path_to_my_keystore.keystore" -alias my_alias 
>> -keyalg RSA -validity 1

then input some information... The result is like this : "Generating
1,024 bit RSA key pair and self-signed certificate (SHA1withRSA) with
a validity of 10,000 days".
Then,

>> jarsigner -verbose -keystore "path_to_my_keystore.keystore" %FILE_NAME% 
>> my_alias

then enter correct passphrase...
The result is an APK file with sign.

But when I install this APK to emulator/device, It fail with message
Failure [INSTALL_FAILED_INVALID_APK].

So now, I don't know how to continue...
Please help me ...
Thanks in advance. :).

streams, so can the player support to switch among them? Until now, I
didn't find any code to support it

[android-developers] Re: Build APK file from command line...

[Xavier Ducrohet]

Use the -u option to create an unsigned package and then call
jarsigner to sign the generated apk.

[android-developers] Re: Can't i call a service function in activity's onStart/onCreate?

[bear tung]

Thanks.
I want to know when the the service connection is connected. It seems like
won't connected before the ui show up.

The thing i what to do is show the UI based on the servie's some function's
return value. There is something like callback function when the connection
done?

[android-developers] is there a way to simulate a dropped connection in the emulator?

[sdphil]

maybe more importantly going out of range.

specifically going out of data range (not voice).  i.e. i'm browsing
for something and I go out of range.

or to control the speed of the connection?

tia.

[android-developers] Build APK file from command line...

[HandsomeboyIT]

Hi everyone,
I want to build the .apk file from java binary file (.class) or .dex
file. I have copied the bin+res folder and Manifest.xml file to a
specified folder. and run the command :

[apkbuilder.bat %FILE_NAME%  -rf  "./src_folderr"]

this command build the new .APK file with default keystore...

But I want to build the APK with me generated keystore, with command
line as this :

[apkbuilder.bat %FILE_NAME%  -rf  "./src_folder" -storetype
path_to_my_release_keystore.keystore]

but it can not find my keystore with
"java.security.KeyStoreException : release.keystore not found"

How can I build APK file with my keystore file ???

Thanks.

A bug stating that you can't instantiate a RotateDrawable in Java and

[android-developers] How to rotate a drawable programmatically?

[Micah]

In my application I want to be able to rotate a view programmatically
rather than via XML.  I can easily create a  drawable that
references my Drawable, but I can not figure out how to do the same
thing in Java.  The problem is that many drawables in my scene can be
displayed either vertically or horizontally and I do not want to have
to create a separate rotate drawable for every drawable in my scene.

One thought I had was to instantiate a RotateDrawable in Java and then
use that as the background for my view, but it does not appear that
you can set the rotation of a RotateDrawable instantiated this way
(you have to feed it XML to get it to be at all useful from what I can
tell).

Another thought I had was to rotate the canvas, but I would like to be
able to use the drawables as view backgrounds and I do not see a way
to rotate the canvas before the background of a view is drawn and then
revert it afterwards.

I also looked into creating some generic rotate drawable and then
perhaps changing the drawable that it applies to, but that lead no
where.

So, does anyone have any ideas about how I can rotate a drawable in
code and then use that rotated drawable as a background?

[android-developers] Re: REGRESSION - trap in android 1.6 SDK inflating DialogPreference from XML

[Romain Guy]

DialogPreference is an abstract class and cannot be instantiated.
There was a bug in the VM in 1.5 that would allow abstract classes to
be instantiated through reflection. Sorry it broke your app but the
1.6 behavior is the correct one. Having an instance of an abstract
class is very wrong and could lead to all sorts of problems.

[android-developers] Re: Android XML Schema Location

[Dianne Hackborn]

It's the namespace that the android framework resources live in.  It's just
a namespace, but if you change the namespace, you totally change the meaning
of the XML file because by definition all attributes that were in the old
namespace have changed their identity to something unrelated in a different
namespace.

[android-developers] surfaceflinger & compiz

[Westermann Fu]

Hi, All:

I don't know whether this is the right place to post my question, maybe my
question is more related with android framework design. I think android is
designed with "composited desktop" in heart, here I mean each window doesnot
render itself directly on screen, rather they are rendered to separate "back
buffers" without any clipping applied (such as obscured by other windows),
then the surfaceflinger compose these backstores into the framebuffer to be
displayed with z-order or clip rectangle applied. It is the lacking of this
feature for core X window in desktop world that leading to xComposite
extension which at last leading to compiz to be born. My question is, for
compiz, not only simply to composite each window backstores to framebuffer
but rather it provides a plugin mechanism that user application can
customize the behavior before/in/after the composing process, so such as
water effect, magnifier tools/effect can be implemented easily. But for
surfaceflinger, is the compose behavior fixed? Do surfaceflinger or
windowmanager service or anyone others provide the similar "plugin"
interface for application to use for customizing the compose behavior, or
the only way left is hacking surfaceflinger? Thanks.

Regards

Westermann Fu

[android-developers] REGRESSION - trap in android 1.6 SDK inflating DialogPreference from XML

[Lee]

Code that was working fine on 1.5 is now trapping on 1.6 while
inflating a DialogPreference.  I've got a tab host and one of the tabs
is hosting a PreferenceActivity.  In the onCreate of the preference
activity the preferences are loaded from XML using the following call:

public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
 }

The stack trace is shown below - this seems like a regression from
1.5...

[android-developers] Re: Android XML Schema Location

[Mihai Fonoage]

But if I change the identifier to something else, it does not work,
hence the "http://schemas.android.com/apk/res/android"; value of the
namespace has to have some kind of (internal) meaning. I get though
that the validity of the attributes is based on the parent element (as
per my understanding), but this does not explain why it will not work
with a value of "http://mihai/fonoage"; for example.

Thank you,

While it's not a common case, there ARE cases in which it makes sense
to have a long running service with two processes.  The case I have in
mind involves a media player with all the associated content
management.  I agree that in most cases it's a bad idea to have long-
running services or two processes, because most services are of the
"wake up when there is something to do" model.

There are two layers involved.  I have a lot of confidence in the
underlying native layer, which has a pretty clear story on the various
levels of locking (database, table, or page-level).  Write locks are
accomplished by locking the entire database, which is perhaps ok if
most of your access is to read.  More sophisticated databases will
allow simultaneous writes from different processes by page-level or
table-level locking, but at least SQLite has a clear guarantee and a
reasonable expectation of performance.  See http://www.sqlite.org/lockingv3.html
for a more thorough discussion.

On the other hand, the android SQLite API on top of the native layer
is a different animal.  In particular if you look in
SQLiteOpenHelper.getReadableDatabase() there is a line that says
"return getWritableDatabase()".  That's one way of satisfying lock
constraints, but it also seems to imply that all locks (read or write)
are exclusive to a process and lock the entire database.  If an
application in one process has a CursorAdapter, then it will
periodically have to reacquire a lock in order to call
SQLiteQuery.fillWindow(), but if there is another process writing to
the database, then the application is going to block.  I haven't
unwound the spaghetti to resolve this issue, and the documentation is
unclear on the point.

I am not claiming that "there is a consistency problem"; only that
there is a lot of ambiguity about what kind of performance will be
delivered, and what the semantics are on locking at the android API
layer.  That's why I was advocating the use of the ContentProvider
APIs, because it says that it uses a single process to handle
locking.  Thus there is no doubt that you can have multiple readers
because the lock will be shared.

[android-developers] Android XML Schema Location

[Mihai Fonoage]

Hi,

The Android XML Schema is declared in the xml files as being at
"http://schemas.android.com/apk/res/android";. Since this URL is not
found, how does Android validate the xml attributes that are in the
Android namespace? I am guessing the schema file comes bundled with
the SDK, in which case where is it located?

[android-developers] Re: Start the CallLog Activity via Intent

So it obviously cannot find an activity that can handle the Intent.
Does somebody know why? Wrong URI? Wrong action?

Ah, yes -- sorry, but the custom View was causing a mental block.

There is an onFinishInflate() method you can override that gets control,
well, when the inflate is finished. There, your children are ready and
you can have them do what you want.

[android-developers] rules for inflating layouts

[Jason Proctor]

sorted it out. can't call findViewById() in the ContactView 
constructor, as its tree hasn't been inflated under it yet. at least 
i think that's what's going on.

the ListView can see ContactView children just fine.

thanks for the responses, chaps.

[android-developers] Re: android 1.5 and 1.6 versions of SDK sitting side by side...

[Xavier Ducrohet]

You have most of it.

the --target value that you project to 'android create project' or
'android update project' will define what APIs you compile against.
If you want to use APIs from 1.6 you need to update your project with
the 1.6 target.

(The new SDK, starting with 1.5, can contains multiple versions of the
APIs. So if you install 1.1, 1.5 and 1.6 in your SDK, you could work
on different applications using different APIs at the same time. You
PATH environment variable only need to point to the tools folder of
your single SDK. When a new SDK is realeased the new SDK updater will
allow you to add/update your current SDK instead of downloading a new
one in a different location.)

The content of the  is used at install time (and allows
Market to filter out which apps are seen by which device).

you could technically compile against Android 1.6 but declare
minSdkVersion=3 (== Android 1.5) but if a 1.5 device tries to execute
the new APIs it'll crash.

You might want to read
http://android-developers.blogspot.com/2009/04/backward-compatibility-for-android.html
for information about how to support older devices while using new
APIs.

Well, I suppose you do have a point.  I just thought that 1.6's
"proper" release was a bit more imminent.

I'll check back once Donut's fully ready for prime time, then.
Thanks!

The closest thing to what you are asking is to export an interface via AIDL:

[android-developers] Re: android 1.5 and 1.6 versions of SDK sitting side by side...

[sdphil]

okay, so I have 1.5 and 1.6 co-existing on my dev boxes / build
machine.

I change my manifest to still say:



I'm not sure what happens when I need to use a 1.6 feature.

The build script still uses

android  --target 2 

So that it can support 1.5.

I guess what I'm doing then is compiling my code which was designed
around 1.5 using the 1.6 SDK.  It should theoretically just install on
a 1.5 phone, right?

Then what happens if i start using 1.6 features?  I assume at that
point i need to do something like

android  --target 4 

But then what happens when I install on a phone with 1.5...

tia.

[android-developers] rules for inflating layouts

[Jason Proctor]

thanks for the response.

i'm effectively calling contactView.findViewById(), as the call is 
from ContactView itself.

i tried the suggested inflate() usage, no change on the behaviour 
though. ContactView still claims it has no children, and therefore 
findViewById (contact_top_layout) doesn't find anything.

thanks for the response.

that's effectively what i'm doing, as the findViewById() call is done 
from inside the ContactView.

sorry if the code wasn't clear -- ContactView is the custom item View.

[android-developers] Re: rules for inflating layouts

What Mark said. Also, the correct usage of inflate() in adapters is:

inflate(layoutId, parent, false);

Passing the parent (given to you as a parameter in getView()) allows
the UI toolkit to create the appropriate LayoutParams object. Passing
false tells the toolkit to NOT call parent.addView(theInflateChild),
since ListView will do its own magic later on.

Hi!

I have some similar question.
APK1 (not service) has public class A.

How should I write class A or APK container to make it visble and
"importable" from some other APK? In other words I need to use my first APK
as library.

Please advise.

Thanks in advance,

Try contactView.findViewById().

You do not need two processes for an application with a long running
service. Not to mention that long-running services aren't a great idea
in the first place.

SQLite handles cross-process locking. That's one of the reasons why it
is the default database for Rails and other Ruby server-side frameworks
that rely on multiple processes.

[android-developers] rules for inflating layouts

[Jason Proctor]

i thought by now you could read my mind :-)

assuming that the XML enclosed in the post is in res/layout/contact_view.xml

in the custom ListView...

LayoutInflater  inflater = LayoutInflater.from (this.context);

// passing null here, as i'm assuming that the ListView will hook the 
view up with its hierarchy
ContactView contactView = (ContactView) inflater.inflate 
(R.layout.contact_view, null);

in the custom item View...

LinearLayouttop = (LinearLayout) findViewById (R.id.contact_top_layout);

"top" comes back null. if ContactView asks for its own children, the 
count comes back zero.

thanks in advance!

"when asked for its children" -- when who is asked?

Not sure what qualifies as "funky rules". Here's a sample chapter from
one of my books that explains the process:

http://commonsware.com/Android/excerpt.pdf

If this doesn't help, write back with some Java code of where you are
doing the inflation and what calls seem to be failing.

[android-developers] Re: Content Provider VS SQLiteDatabase

[GeezIHateCreatingNewNames]

I've also struggled with the the distinction between a ContentProvider
and just using a sqlite database.  Clearly if the application is
exporting data to other (potentially unknown) applications then a
ContentProvider would make some sense.  The more complicated case
seems to be a single application that has two processes in it (e.g, an
application with a long running service).  In this case it seems like
you could simply share at the sqlite database layers, but the locking
and sharing story on the sqlite database APIs is somewhat unclear.  By
using the ContentProvider APIs, it looks like you sidestep these
issues because all access to the database will be through a single
process and ContentResolver provides a bridge between the processes.

[android-developers] Problem with network location provider

[David]

Hi, there:

I downloaded the cupcake branch and compiled to get a new system.img.
I flashed the img to my G1 phone; then I checked the available
location providers, but only gps is available. The networkprovider
just is not there!

Before the flashing, both gps and network providers are available.

Can anybody tell me why network-provider is not working? Note that it
is not a enabling/disabling problem, since I enabled them in the
Settings.

Thanks.
David

[android-developers] Re: MediaPlayer PVMVErrTimeout error

[Mark Skiba]

After looking at related MediaPlayer discussions, I can discount a couple of
possibilities:- my MediaPlayer is attached to the application object and is
not affected Activity lifetimes (handles rotations ok)
- the MediaPlayer creation and play are done in a separate thread than the
activity thread

[android-developers] rules for inflating layouts

[Jason Proctor]

i'm running into some issues inflating layouts and i wonder whether i 
have something basic wrong.

i have a ListView with a custom adapter etc, and of course the item 
View is custom too. i've been creating the item View in code, and 
everything works fine, including recycling them and all that. great. 
but i want to move the View into a resource, where all good Android 
views live, and weirdness is happening.

in the ListView's getView(), i get my inflater and inflate the view 
by ID. the view itself has its own XML file. i can inflate the top 
view, but i can't find anything by ID, and when asked for its 
children, nothing comes back.

are there funky rules for inflating views this way? is there a 
convention for how this should be done inside a ListView?

thanks -- (abbreviated) XML layout code enclosed...

[android-developers] Re: zipalign and Proguard

[Xavier Ducrohet]

It's completely different.

The only thing that zipalign does is align the location of the
uncompressed zip entries on 4 bytes by adding padding before them
(using the extra field of a zip entry).

The content of the files inside the zip archive is not changed in
anyway (otherwise the signature would fail)

It has been on backorder for some time. You may wish to keep an eye out
for one on eBay or something.

Also, since some people get confused by this, you only need the ADP1 if
you are going to modify and test firmware changes. For ordinary
applications, any Android device is fine for testing.

[android-developers] zipalign and Proguard

[Fred Grott(Android Expert)]

As you mightknow new to SDK 1.6 is the zipalign to align data
resources for better and optimized performance and it gets used after
apk is signed.

My question is how does this affect those who may be obfuscating their
classes by using Proguard?

Will I stil be able to obfuscate the classes using Proguard?

Thanks

[android-developers] MediaPlayer PVMVErrTimeout error

[Mark Skiba]

I'm writing a streaming music player application and I frequently get
a "PFMVErrTimeout" error generated by the PlayerDriver according to
the ADB log.  This appears to happen even with good reception.  I
can't seem to find any documentation on this error message.

What does a PFMVErrTimeout" error indicate?

Is there anything that can be done from an application that can
eliminate or minimize this error?  Is there a way to recover other
than freeing up the MediaPlayer and creating a new one?

Also, what is the ERROR/PlayerDriver(26027): HandleInformationalEvent:
type=28 UNHANDLED refer to?  Do I need to add an event handler for
this?

This error seems to be mostly associated with the "/dalvikvm(55): GC
freed" event.

[android-developers] Re: wrap around with textview in a tablelayout broken

[Fabian Sturm]

Hi!

Thanks for your testing, at least I now know I am not doing anything
stupid :-) And yes I guess I could use something different for the
layout, I just thought the tablelayout would be the most logical choice
to get all items in the second column aligned properly.

Anyways I opened this bug report
http://code.google.com/p/android/issues/detail?id=4000 
but no one looked at it yet.

Thanks a lot, Fabian

Ah, found the message in dalvik/dx/src/com/android/dx/dex/file/
ClassDefsSection.java.  Comment there says:

/**
 * Adds an element to this instance. It is illegal to attempt to
add more
 * than one class with the same name.
 *
 * @param clazz {...@code non-null;} the class def to add
 */

The "dx" command wants to take your various classes and combine them
into a single, large .dex file.  It wouldn't make sense to have more
than one copy of the same class -- one would never be used and would
just take up space.

Assuming you need parts of all of the involved jar files, you can
probably work around this by unzipping the jars into a single
directory (which will allow "unzip" to overwrite or skip redundant
entries as you prefer) and then create a new jar from that directory
hierarchy.  I don't know if this is appropriate for your situation.

[android-developers] Re: G1 crashing BatteryStatsImpl.writeLocked() OOM

[rflexor]

Hi again,

to anyone interested, here is the solution:

I found out that BatteryStatsImpl persists its state to /data/system.
The batterystats.bin-file there also was 1.5M big. Gladly I got
information from one of the developers that this is far from normal.
The command

dumpsys batteryinfo

helped great deal to find the culprit. In this case an application on
my device that had reserved wake-locks with a random string as a name
for each one. After 75k wake locks things began to go wrong. Deleting
the application from my device resolved the issue. At the next
periodical persist of the batterystats.bin-file, it's size went back
to normal 28k.

You just want your  element, not the android:permission
attribute. Also, you may wish to move that  up earlier
in the XML -- some of this stuff seems (unfortunately) a bit
position-dependent.

Nothing else leaps out at me. Check logcat and see if you get any
warnings -- if Android has difficulty invoking some component, that
tends to get logged as a warning.

Create your own adapter class from BaseAdapter, and you can traverse

Zip align has to be done after the APK is signed. If you use ADT to
create your final, signed, release apk then it'll be aligned too.

But if you sign your APKs outside of Eclipse/Ant, there's nothing we can do.

was hoping somebody could have a look at my code please and let me
know if there are any problems.

[android-developers] Routing Audio to earpiece instead of speaker

[Puneet]

I am writing a voice application for HTC-G2 (MyTouch) phone. I am
using Audiotrack class to play audio in PCM format. It works fine but
audio comes out from speaker phone instead of earpiece. When I use
IsSpeakerPhoneOn() to query the status of speaker, it comes out to be
"off" (false).

I even tried SetSpeakerPhoneOn(true) and then SetSpeakerPhoneOn(false)
to make sure that I explicitly set the speaker to off but audio still
comes out of speaker. Interestingly, I checked IsSpeakerPhoneOn()
after setting SetSpeakerPhoneOn(true) and that API returned False.

I tried setRouting API to set ROUTE_EARPIECE but that API seems to be
deprecated.

Can someone please tell how to route audio to earpiece? I was under
the impression that earpiece shall be the default route for audio but
it does not look that way.

[android-developers] Re: activity is destroyed when press home key

[Johan Schöring]

That's what the documentation says, but that's not what the
ActivityManager does.

>From what I can see, the problem lies in the following code:
http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=services/java/com/android/server/am/ActivityManagerService.java;h=a473db2740abe124b7867d0ea6313eb8c0ca7a7d;hb=5550ef48739a7bb16f80aa6b10e9c151b1438163#l

The if-statement on line  causes the activity stack to be cleared
if the launch mode is singleTask, regardless of the state of
FLAG_ACTIVITY_CLEAR_TOP... In my opinion, this is a bug, as the
documentation you quoted clearly says that the stack should be
preserved on a singleTask activity.

I'm going to submit a patch for this, but I'm writing here so others
who find this thread know that this behaviour is not their fault but a
bug.

[android-developers] Re: Closing one activity from another

[Jeff King]

Override the onActivityResult for all your activities to call finish()
if they get back RESULT_OK. Have your last activity setResult
(RESULT_OK); before it finishes.

[android-developers] Convince Dalvik to add a class with the same canonical path as another

[tomlotterm...@googlemail.com]

Hi!
I'm using a library of a friend of mine and it is build up in a way
that some classes have the same canonical name (in other jars)... I'm
not quite sure how he does it, but it does not lead to a jar hell and
the normal sun java compiler doesn't worry about it...
Now I want to use the library in android and now dalvik comes in and
says:
UNEXPECTED TOP-LEVEL EXCEPTION:
java.lang.IllegalArgumentException: already added: Lnet/xeoh/plugins/
remote/ExportResult;

Seems to be a security to prevent android from having a jar hell, and
now I wonder if i can tell dalvik that this is very nice of it, but
that I don't really care, and that it should add it anyway?

Cheers

[android-developers] Re: activity is destroyed when press home key

[Johan Schöring]

That's what the documentation says, but that's not what the
ActivityManager does.

>From what I can see, the problem lies in the following code:
http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=services/java/com/android/server/am/ActivityManagerService.java;h=a473db2740abe124b7867d0ea6313eb8c0ca7a7d;hb=5550ef48739a7bb16f80aa6b10e9c151b1438163#l

The if-statement on line  causes the activity stack to be cleared
if the launch mode is singleTask, regardless of the state of
FLAG_ACTIVITY_CLEAR_TOP... In my opinion, this is a bug, as the
documentation you quoted clearly says that the stack should be
preserved on a singleTask activity.

I'm going to submit a patch for this, but I'm writing here so others
who find this thread know that this behaviour is not their fault but a
bug.

[android-developers] jsonarray as listview source

[vorcigernix]

Hello,
I made my application from various examples and sources, so now I have
filled jsonarray and prepared listview (with custom rows formatting).
Now I need to replace

ListAdapter myAdapter =(new ArrayAdapter
(this,R.layout.rowlayout, R.id.TextView01, values));

with my json array based adapter. All I found is some technique to
iterate through all json records and construct string array. It sound
like perverse to me, is it really necessary?

Thanks for any help
Adam

the latter one. And you need to clear the focus index, the name of the

[android-developers] Re: Progress bar not visible with a white background in 1.6 sdk

[Steven Rudenko]

There are some themes of activity which can help You with UI. When You
are using dark backgrounds use @android:style/Theme.Black theme
otherwise use @android:style/Theme.Light. These styles will provide
correct colors to all controls (like progress bar).

[android-developers] Getting media information that is being played

[Alex]

Is there a way that I can get the media information (song title,
genre, artist, etc) that is being played in the default music player?

Does the default music player allows sharing of these kind of
information?

Thanks.

[android-developers] Re: Missing timezone

[Simon]

I have a similar problem.  I am in Pakistan where the timezone is
normally GMT + 5.  However at the moment we are in + 1 DST, i.e. GMT +
6.  Android thinks that Pakistan is GMT + 5 throughout the year.  I
have the same problems as you with text message and google calendar
times.  I too would appreciate any advice or suggestions to manually
correct this.

Thanks

[android-developers] Re: zipalign : could be done at distribution or installation time ?

[Sheridan Hutchinson]

I just cannot understand why when a developer uploads an application,
why Google themselves don't automatically zipalign the application.

I just cannot undestand why the compiler doesn't zipalign
automatically every final APK produced.

[android-developers] Re: ADC2: Low volume of judges

[Warren]

It's true that some apps will be rated lower because they don't apply
to the user doing the judging. For instance I judged an app that was
designed specifically for users in Paris. It was low for me on the
indispensability scale as it would be for most people not in Paris.

BUT if it is clear from the outset that the app does not apply to you,
then you might skip it. This could lead to higher concentration of
judges who say, "Ahh, an app that serves my niche!" actually scoring
the app. For instance, an app named, "Find the Closest Bathroom in
Paris" would probably be skipped quite a bit by people not in Paris.
You might end up with 75% of the judges for that app actually being
from Paris. But if the app is called "Bathroom Finder" and gives no
hint that it is geographically limited, you'd get no such effect.

 Who knows? This is all just conjecture and guessing.  The effects
might balance each other out. They might not. There won't be a clear
picture until Google releases some results... maybe not even then.

I don't really agree with the "MY needs" line personally. We are
acting as judges - and therefore should also take into consideration
how an application would be useful to others. For example, I
personally dislike most social networking applications, and do not
even bother to use twitter or facebook outside of Android. Rating most
social network application badly and giving them "1s" in
indispensability due to my personal preference would not be right, in
my opinion. Of course, I do skip most of those related to this
category, just saying I think there might sometimes be more to it than
"what does this app do for me".

[android-developers] Re: zipalign : could be done at distribution or installation time ?

[Dianne Hackborn]

I don't think market will ever run it (it really doesn't want to make any
changes to the apps it is distributing).  At some time in the future we'd
like to consider having the platform do it during install, but this is a
lower priority than a lot of other things.  If someone wants to contribute
code to do it, I am sure we'd be interested.
