 Topic: onCreate, onStop..... super.onCreate, super.onStop... called before code or after?

Moto <medicalsounds@gmail.com> Jul 31 07:26PM -0700 ^

 
This might be a simple question but I'm seeing the super call at the
end of the overwritten function and also at the start of the
function. What is recommended? any differences on this?
 
I feel very beginner with this question... :P
 
i.e.
 
@Override
protected void onCreate)
{
super.onCreate();
// some code
}
 
or
 
@Override
protected void onCreate()
{
// some code
super.onCreate();
}

Probably there are exceptions to every rule.
 
In this particular instance I would probably have the base class
complete its work before I do the work of the derived. May be a poor
parallel, but if I am constructing a multi-story house, I would want
to finish the base floors and move on to the upper floors.
 
Another thought is, a derived class comes later in conception than the
base class. So a derived class can anticipate what a base class does
on the otherhand baseclass designers would not have known what the
derived class would have done.
 
In case of a constructor, the compiler will tell you that you have to
call the super first.
 
However if I know that I am not altering the state of the base class,
such as logging a message, I could put that method either before or
after.
 
Also if you want the behavior of the base class to be a default one
after you have exhausted your options such as attending to menus, then
you want to call the base super last.
 
In the particular case of "onCreate", as it resembles construction, I
go with calling the "super" first.
 
Hope this reflection helps

 Topic: Design similar to the home screen on Twitter and Facebook

Chris Stewart <cstewart913@gmail.com> Jul 31 10:40PM -0400 ^

 
An application I'm working on has a use for a home screen like the ones in
the Twitter and Facebook Android clients. Something like a 2 by 3 grid view
that adjusts when viewed in either orientation. I'm nothing short of awful
when it comes to design and I've yet to work out a design in my layout that
resembles what I'm after. I'm curious to see if anyone has run across a
tutorial in their time researching across the web.

 Topic: finish() at onStop causes ANR

James Wang <jameswangcnln@gmail.com> Jul 31 07:30PM -0700 ^

 
@TreKing
Thanks for your replies. We do have some reasons to call finish
because Android did not finish one when another is shown before it.
>Probably, but with your code, not Android.
Document does not say finish is not allowed to be called at onStop.
How to explain there is no problem with calling finish just after
startActivity.
 
@Dianne
Thanks for your replies. We do believe it is a problem with framework.
WindowManagerService.java:
 
private int dispatchPointer(QueuedEvent qev, MotionEvent ev, int
pid, int uid) {
if (DEBUG_INPUT || WindowManagerPolicy.WATCH_POINTER)
Log.v(TAG,
"dispatchPointer " + ev);
 
if (MEASURE_LATENCY) {
lt.sample("3 Wait for last dispatch ", System.nanoTime() -
qev.whenNano);
}
 
Object targetObj = mKeyWaiter.waitForNextEventTarget(null,
qev,
ev, true, false, pid, uid);
 
When calling finish() after startActivity,
mKeyWaiter.waitForNextEventTarge returns activity A. And after
checking A.isVisibleLW(), the key up event is discarded successfully.
 
When calling finish() at onStop, ANR happens in
mKeyWaiter.waitForNextEventTarge and it is seems never get out.

Why so surprised? The main Android SDK is Java-based, which does not have
preprocessor. Whatever you've used with other platforms are exceptions, not
the norm. I would actually be surprised if it DID have one.
 
I can't think on mobile programming without preprocessor,
 
Well you better learn real fast =)

Too many configurations of what?

Haven't played with LVL yet, so don't know about that.
Useful? Maybe. Necessary? Doubtful.
 
Ok we can live without it, but codes becomes really unelegant...
 
One could argue that preprocessor macros makes code much worse.

Do you always do what the masses tell you? =P

Anyone else on here use Mobclix for Ad serving? I have seen my revenue
drop from $15 to $9 as in they have removed $6 of revenue! Also they
are not giving impression counts for Ads which I know are being

 Topic: Correct way to kill the application

Eric-
 
You are basing your entire post on the fallacious assumption that it
is only "non-technical people" who download the task killers. I am
very technical, and I downloaded one. Nor am I alone.
 
Nor is it that "people ar very bad at shifting". Rather, the recent
trend in the mobile OS industry (not just Google) of forcing it on
people is obnoxious, and has inspired a reaction.

 Topic: LVL returns always LICENSED...

sblantipodi <perini.davide@dpsoftware.org> Jul 31 05:20PM -0700 ^

 
Hi,
I have built in the Sample code from LVL and putted it into my main
activity.
 
I haven't understood why it always returns LICENSED also if I setted
UNlicensed from my developer console.
 
this is the adb logcat output...
 
I/LicenseChecker( 496): Binding to licensing service.
I/LicenseChecker( 496): Calling checkLicense on service for
packageName
I/LicenseChecker( 496): Start monitoring timeout.
I/LicenseChecker( 496): Received response.
I/LicenseChecker( 496): Clearing timeout.
 
I have no idea on why it gives me always licensed...
 
Thanks.


 

 Topic: Correct way to kill the application

Adal <arpia49@gmail.com> Jul 31 10:49PM +0200 ^

 
I think the user is not always the problem and if it is... we've got a
problem because we can hardly make people change their behave, what we can
do is build better apps that don't take resources they don't need. That's a
developers fault and that's the one developers should focus.
 
If we keep thinking users are idiots instead of giving them better apps and
better phones so the realized thinks are evolving we'll see how users go to
other products.
 
That's why (some) people root their phones and install some not official
ROMs, cause vendors what to sell better/newer phones even if the old ones
could be (sometimes) upgraded.
 
I think "auto terminate" functions are only as good as the worst app
installed on your phone.
 
(I hope my message could be read, my English is far from perfect)
 


 

Indicator Veritatis <mej1960@yahoo.com> Jul 31 05:19PM -0700 ^

 
Kostya-
 
Most of what you say is true, but beside the point. Task killers per
se do not "interfere with the platform's functionality".
 
Now yes, some users do have the strong desire you allude to, but that
is far from proof that the desire for Task Killers IS an example of
this effect. I do not believe that it is.
 
On the contrary: I know that the performance of my handset is
sometimes improved by killing tasks that Google decided to leave
running even long after I finished with them.
 
Besides: even your Windows example is not as you would have it. Many
registry cleaners, especially the free ones or the 'crippleware', are
junk, but there do exist genuine cleaners that work well. I have often
resuscitated a sick Windows system by running a high quality registry
cleaner on it. So again, the problem is not that they serve only a
psychological need, but rather that some are genuine and many are not.
 
You should also remember that much of the work these registry cleaners
do became necesasry only because 3rd party programs fail to clean up
after themselves when they do an install or uninstall. If every 3rd
party app behaved exactly according to Microsoft rules, the registry
cleaner would be unnecessary; but that was a vain expectation, doomed
to be disappointed.
 
Why wouldn't the situation be the same with Android Task Killers? The
one I chose, as I already mentioned, really does improve performance
at least some of the time. And I do have a strong suspicion that it is
the 3rd party apps failing to follow Google rules concerning the
lifecycle that make Task Killers useful. The app I downloaded for
reading NY Times feeds, for example, fails to show progress, comes up
with frequent ANRs and occasional crashes.
 


 

 Topic: How to solve this problem: Close Force Error when trying to populate viewStub

kivy <victoriasarabusse@gmail.com> Jul 31 05:11PM -0700 ^

 
Hi there,
 
I just ran into a problem, while trying to populate a ViewStub by
tapping an ImageButton within a SlidingDrawer (the ViewStub should
also be part of the drawer), but all I get is a Force Close Error due
to a Null Pointer Exception. As I am using ViewStubs for the first
time I am not sure, what may have caused the exception. If someone
could help me out with this issue, this would be fantastic.
 
Thank you in advance.
 
This is the code I use to inflate the ViewStub:
 
btnExposure.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v) {
importStub = ((ViewStub)
findViewById(R.id.stub_exposure)).inflate();
 
}
});
This is part of the Sliding Drawer xml file containing the ViewStub:
 
<ViewStub
android:id="@+id/stub_exposure"
android:inflatedId="@+id/exposureview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#77000000">
</ViewStub>
This is the exposureview.xml (the inflatedID):
 
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<SeekBar
android:layout_width="wrap_content"

 Topic: How to cite/reference free images

AUandroid <thevking@gmail.com> Jul 31 12:39PM -0700 ^

 
Hi All,
 
I am about to release my first app on the market for free. How should
I reference or give citations to images I have used in my app. I have
used two images which are free images available at
http://commons.wikimedia.org/wiki/Main_Page
 
thanks,
-vk


 

Streets Of Boston <flyingdutchie@gmail.com> Jul 31 03:22PM -0700 ^

 
One possibility is to have an 'About' screen, reachable from your menu
or from your settings/preferences activity. Put the references/
citations in the About screen.
 


 

AUandroid <thevking@gmail.com> Jul 31 04:22PM -0700 ^

 
thanks for the tips. As I told you its my first time publishing a app.
Can anyone please have a look at this image and let me know what I
must write in my about page.Is it ok? if I just provide this link in
my about section http://commons.wikimedia.org/wiki/File:Nuvola_apps_important.svg
or I must specify any license information. I am using it when ever I
want to alert the user.
 
Thank you,

 Topic: Using a new generated Keystone for existing app. Any possible outcomes?

Moto <medicalsounds@gmail.com> Jul 31 03:24PM -0700 ^

 
Hi,
 
I currently have my application signed using a keystone key I
generated. Could I use a new keystone to sign my application for the
next update?
 
Any issues that could arise if I use a different keystone?
 
Thanks!
-Moto


 

Moto <medicalsounds@gmail.com> Jul 31 03:26PM -0700 ^

 
keystone = keystore :P
 


 

Moto <medicalsounds@gmail.com> Jul 31 03:32PM -0700 ^

 
Oops never mind :( You can't do that...
 
http://developer.android.com/guide/publishing/app-signing.html
 
"Application upgrade – As you release updates to your application, you
will want to continue to sign the updates with the same certificate or
set of certificates, if you want users to upgrade seamlessly to the
new version. When the system is installing an update to an
application, it compares the certificate(s) in the new version with
those in the existing version. If the certificates match exactly,
including both the certificate data and order, then the system allows
the update. If you sign the new version without using matching
certificates, you will also need to assign a different package name to
the application — in this case, the user installs the new version as a
completely new application."

sblantipodi <perini.davide@dpsoftware.org> Jul 31 03:17PM -0700 ^

 
How can we use ServerManagedPolicy in the emulator and fastly switch
from licensed to unlicensed to something else?
 
The first time I got the licensed message, than I'll continue to get
the licensed
message also if I set UNLICENSED from my developer console after I
deleted and reinstalled the app on the emulator.
 
Thanks.

The absence of preprocessor has to do with Java, not Android.

Frank Weiss <feweiss@gmail.com> Jul 31 01:34PM -0700 ^

 
Here is a long thread on the subject:
http://groups.google.com/group/android-developers/browse_thread/thread/1c9078176b172e1a/235bae6530ee7e74?show_docid=235bae6530ee7e74
 
There are Java projects that use various preprocessors. The lack of a
standard one is a problem. AFAIK Sun's WORA ideology ran against the
need for a preprocessor, although many developers think that mobile
platforms have taken a big bite out of WORA. Modern software
development methodologies, such as refactoring to patterns, tend to
use other approaches for making software flexible and reusable.
 
Personally, I'm glad Java does not have a preprocessor. It just seems
a much cleaner language that way, that is, I have never yet seen Java
code with ifdefs. But I can understand that it can be very useful
under certain circumstances.

Quite easily, actually.

Is this is a serious question? Have you browsed through the Android Market
(as painful as that is)? There's a lot more out there than "fart apps".
 
 
> I don't want to troll but I really can't understand why I heard

Probably simply because it's an alternative to iPhone.
 
 
Now, someone with your experience developing for so many devices can surely
adapt to not having a preprocessor. It's good for many things but definitely
not a necessity and will certainly not cripple you when making an Android
App.
 
If you're personally that attached to having a preprocessor, no one is
forcing you to develop on Android.
 
Good luck.

I'm sorry for my rude and really not too much kind speaking,
but I can't belive that android doesn't support preprocessor.
 
I can't think on mobile programming without preprocessor, too many
different configurations,
think only to LVL and android market and preprocessor could be
useful...
Ok we can live without it, but codes becomes really unelegant...
Sincerely I really don't like the non preprocessor way but
unfortunantly,
masses told that android is good and I need to develop on it :)
 
 
 


 

Streets Of Boston <flyingdutchie@gmail.com> Jul 31 03:16PM -0700 ^

 
I'm glad to not have to use pre-processors and hash-defines.
I hated them when i worked in C (and C++) (they tended to get over-
used, made code unreadable and difficult to debug) and for the last
decade of Java programming i really never ever needed them.
 
"How can you develop on a mobile without preprocessing?"
Easily, no problem.
 


 

 Topic: LVL NOT_MARKET_MANAGED

Brian <avalon73@caerleon.us> Jul 31 02:45PM -0700 ^

 
I've done some testing on this, myself, and it seems that it only
returns the NOT_MARKET_MANAGED error for an app in the market if the
version code (the integer form of the version number in the manifest)
in the copy making the check is higher than the one currently in the
market. If the version code in the copy of the app making the check
is less than or equal to the current one in the market, then the
normal license valid/invalid response is given unless there's another
error.
 
That seems acceptable to me, even if it is a bit odd considering the
docs imply that it indicates only a package name mismatch.


 

 Topic: Android Market Licensing: Now Available!

keyeslabs <keyesdav@gmail.com> Jul 31 02:21PM -0700 ^

 
Speaking as someone who has traveled this road before with my own
implementation of basically the same approach, obfuscation will be
critical. With AAL, it took about three days for someone to crack the
app. The process looks something like this: decompile the apk using
a freely available open source tool, find the code that invokes the
licensing check, skip it, recompile and repackage the apk.
Obsfucation will make this more difficult, but not all that tough
given the usage of intents for communication between LVL and the
market tool.
 
Don't get me wrong, I think that LVL will offer a much needed road
bump for pirates -- stealing apps will actually require a crack of
each app. This is a viable approach to license verification and
that's why I took the same route with AAL months ago. It certainly
seems like google could have gone further though.
 
The coverage of this has been very extensive in the press, and I would
guess the coverage of the first released crack within a week or two
will also make a fairly big splash, which won't look great for the
platform.
 
All told though, I think LVL is a positive step for the platform.
Speaking as someone that was seeing 90%+ piracy rates before
implementing something very similar to LVL in my own apps, I'm happy
to see google addressing the problem.

 Topic: Missing network functionality?

RickB <rick.bullotta@comcast.net> Jul 31 01:30PM -0700 ^

 
Can any version of Android support simultaneous connections on both a
mobile network (e.g. 3G) and a WiFi network? Here's the requirement:
 
I want to connect to a local Wifi network of sensors/devices that is
not connected to the Internet, and be able to transmit data to an
Internet-connected web server. Obviously quite easy to do on
virtually any platform in Java, but it seems that Android does not
allow multiple networks/radios to be active at a time.
 
Big flaw, IMO. Should be a configurable option to allow that.
 
With Froyo and mobile hot spot functionality, clearly it is
*technically* possible to do, but I don't want to be the Wifi "host",
but rather, a "connected client" to another Wifi network, and then do
web requests over the 3G network.
 
Thanks in advance for any suggestions/workarounds.


 

 Topic: Adding headers to listview for cursor with grouped results

Connick <oconnick@gmail.com> Jul 31 03:33PM -0400 ^

 
For anyone looking to dynamically add a header to a sorted cursor in a list,
Kostya's suggestion worked brilliantly. In getView override check the column
value you're sorting on of the previous cursor position to determine if you
need to use a regular row or a view which contains both a header *and* a row
layout.

viewswitcher is probably better for what you are wanting to do
http://developer.android.com/reference/android/widget/ViewSwitcher.html
you can even assign animations for the views as they come and go if
you want.

Im using a setSelection and setSelectionFromTop to scroll a listview
to a certain position but it randomly fails to do anything?!
 
I not calling from another thread. Can it be because I just before
called notifyDataSetChanged() ? In that case how do I know that that

 Topic: Android preprocessor, //#ifdef...

Hi all,
I noticed that there is no way to use preprocessor in android with
netbeans using the
//#ifdef syntax,
 
is there some sort of preprocessing in eclipse using android?
I haven't understood if this is a lack of netbeans or it is a lack of
android.

It's a lack of Java. Preprocessing, specifically the #ifndef notation you
mention, is a C/C++ thing.

 Topic: Android Market Licensing: Now Available!

skooter500 <skooter500@gmail.com> Jul 31 10:56AM -0700 ^

 
This sounds great, but is completely useless to me as Im in Ireland
and no paid apps available to my potential users, so I've gone ahead
and made my own user registration and payment system based around
PayPal. A complete waste of my time, but what can ya do?
 
From Reto Meier:
 
"Unfortunately I can't give you a time-frame for paid app buyer or
seller support for Ireland either. The team working on that side of
things have a lot on their plates so getting even a rough estimate for
any specific country is near impossible."
 
Interesting that Apple, Microsoft, Paypal, Nokia etc can manage this
but Google can't even give me date when it might be available. Not
very professional. :-(

 Topic: Record audio problem on the LG Ally

skooter500 <skooter500@gmail.com> Jul 31 10:50AM -0700 ^

 
Hi guys
 
I have a music recognition app (Tunepal) that records 12 seconds of
audio @ 22KHz (in one second chunks). After each second, the audio is
copied from a byte array into a float array and eventually I perform
some DSP on the float array.
 
My app is available on the Android Marketplace and is selling ok. I
have tested it on lots of different phones, such as the HTC Desire/
Hero/Motorola Droid etc and everything is fine.
 
One of my users has an Lg Ally (running Android 2.1 I believe) and the
recording is not working. In fact it's crashing the app. I have
developed a test program that just records some audio and I think I
have isolated the problem. The test program records audio of various
durations and sample rates and then plays it back. This is the crucial
bit of code:
 
protected Void doInBackground(Void... arg0)
{
System.out.println("Recording started");
audioRecord = null;
System.gc();
int totalBytes = bufferSize;
try
{
buffer = new byte[bufferSize];
audioRecord = new
AudioRecord(MediaRecorder.AudioSource.MIC, sampleRate,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, totalBytes);
audioRecord.startRecording();
 
int bufferReadResult = audioRecord.read(buffer, 0,
bufferSize);
if (bufferReadResult ==
AudioRecord.ERROR_INVALID_OPERATION)
{
message = "ERROR_INVALID_OPERATION returned";
error = true;
}
if (bufferReadResult == AudioRecord. ERROR_BAD_VALUE)
{
message = "ERROR_BAD_VALUE returned";
error = true;
}
if (bufferReadResult != bufferSize)
{
message = "Requested " + bufferSize + " bytes but read
" + bufferReadResult + " bytes";
error = true;
}
}
catch (Exception e)
{
message = e.getMessage();
error = true;
}
 
 
if (! isCancelled())
{
doneRecording();
}
 
return null;
}
 
This code works fine on my HTC Desire, but on the LG Ally, no matter
what the buffer size or sample rate is set to, bufferReadResult always
returns 2048. In other words, the call to:
 
audioRecord.read(buffer, 0, bufferSize);
 
Always reads just 1024 samples of audio. Actually I havent tested to
see if the buffer contains anything useful.
 
I can possibly get around this in my app with a bit of work, but I was
wondering if anyone else has encountered this problem and if there is
a better way to get around it than reading the audio in 2K chunks.
 
You can try out the test app for yourself here:
 
http://tunepal.org/tunepal/android/RecordTest.apk
 
Rotations will screw it up BTW, so keep your phone orientated in
portrait for the test.

 Topic: LVL NOT_MARKET_MANAGED

Pent <tasker@dinglisch.net> Jul 31 08:32AM -0700 ^

 
It seems that this error code is returned if the versions of the app
on the device and at the server differ (amongst other times).
 
What if the user buys on the market, but doesn't get a chance to
validate before the next version comes out ? With a popular app, this
will probably happen every update to someone.
 
Perhaps a separate code would be useful for version codes differing,
so the user can be prompted to update ?

No, AlertDialog is not meant to be modal, for reasons that have been

Definitely no, unless you like blocking your UI thread and having to force
shut it down.

Do what I told you in the the first response.
 
Please read the docs on AlertDialogs and work with some samples. Learn to
use an API the way it was meant to be used. Don't try to bend it to work the
way you would like it to work, or you'll cause yourself massive headaches.

I have had about a dozen reports (and zero on any other phone) so I
imagine something screwy is going on but I can't image what. Several
people have said it only happened after the last OS upgrade

The Droid X hasn't had an OS upgrade yet, so perhaps your users are
either confused (likely) or are reporting the wrong device to you.

 Topic: Library problems

"{ Devdroid }" <webnet.android@gmail.com> Jul 31 03:29PM +0200 ^

 
Hi,
 
I tried to build test library and test app howver Eclipse complains on
each reference I made to library classes.
This is what I did:
 
1. created Test Library Android project, marked it as "Library"
(package name "test.library.lib")
2. created Test App project (package "test.library.app") and set it to
use Test Library
3. Test Library got LibActivity class which simply referes to
lib_main.xml layout
4. I defined that activity in Test App manifest file:
 
<activity android:name="test.library.lib.LibActivity"
android:label="@string/app_name"
android:theme="@android:style/Theme.Dialog"
 
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
 
The problem is that Eclipse now compains "Class
test.library.lib.LibActivity" does not exists".
I also got same problem when I i.e. create a class in Test App that
refers to classes
in library. Import test.library.lib.*; does not help. SDK version is
recent. Target sdk=3 (tried
setting to 8, but made no difference)
 
What am I doing wrong?

 Topic: Library development - Development requirements

"{ Devdroid }" <webnet.android@gmail.com> Jul 31 02:27PM +0200 ^

 
Hi,
 
Can anyone explaing what Table 1 ("Minimum versions of SDK tools and
plaforms on
which you can develop library projects.")'s columns really mean. Table is here:
 
http://developer.android.com/guide/developing/eclipse-adt.html#libraryProject
 
I.e.
 
component: Android 1.5 platform, minimum version: r4 or higher
 
but
 
component: Android 2.2 plaftorm, minimum version: r1 (or higer).
 
Blame my English, but I simply do not get what this minimum version
really refer to. Thanks in advance


 

"{ Devdroid }" <webnet.android@gmail.com> Jul 31 02:55PM +0200 ^

 
> component: Android 1.5 platform, minimum version: r4 or higher
> but
> component: Android 2.2 plaftorm, minimum version: r1 (or higer).
 
Ok, seems I figured out :) That means that to develop library
targetted for Android 1.5,
the SDK Platform Android 1.5, revision 4 (or higher) have to be
installed and to develop
for Android 2.2, one needs SDK Plaform Android 2.2, revision 1 (or
higher) And that,
(and also Android SDK Tools revision) can be checked by launching SDK Setup app
and checking "Installed Packages" list.

You are right - I needn't startActivityForResult() - just

Sure... check for the internet connection before you bother building the
URL and trying to connect :).
 
public boolean IsConnectedToNetwork(Context context)
{
ConnectivityManager conManager = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo[] allNetworkInfo = conManager.getAllNetworkInfo();
NetworkInfo currNetworkInfo;
boolean anythingConnected = false;
for (int i = 0; i < allNetworkInfo.length; i++)
{
currNetworkInfo = allNetworkInfo[i];
if (currNetworkInfo.getState() == NetworkInfo.State.CONNECTED)
anythingConnected = true;
}
 
return anythingConnected;
}

 Topic: How to create a chooser to pick an image with any application?

"Michał Karnicki" <mkarnicki@gmail.com> Jul 31 03:40AM -0700 ^

 
Hi,
 
I tried to createChooser the following way:
 
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
Intent chooser = Intent.createChooser(intent, "Pick an image");
startActivityForResult(chooser, 1);
 
as well as that way:
 
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType(MediaStore.Images.Media.CONTENT_TYPE);
Intent chooser = Intent.createChooser(intent, "Pick an image");
startActivityForResult(chooser, 1);
 
Both take me directly into Pictures gallery. How did Dropbox app
implement chooser for picking a picture with such result (2 element
chooser):
"Pick a picture: //title
- File browser
- Photos/Gallery" ?
 
Both results, for my app and Dropbox example, were tested on the same
device, HTC Hero.

 Topic: Android Market Licensing: Now Available!

Pent <tasker@dinglisch.net> Jul 31 03:12AM -0700 ^

 
It was the obfuscation messing up this line in LicenceChecker:
 
new Intent(ILicensingService.class.getName()),
 
I changed this to
 
new Intent(ILicensingService.Stub.getDescriptor()),
 
and added a correspinding static function in ILicensingService.
 
Since the docs recommend obfuscation, I think the googlers should
change
that line.
 
Havn't finished testing yet but this has at least fixed the 'can't
bind' problem.

However, when I run the application, I always get

07-31 15:03:05.131: INFO/ActivityManager(85): Start proc
com.Myapplication for service com.Myapplication/.MyRunningService:
pid=5045 uid=10077 gids={}
 
The MyRunningService seems to be killed by the OOM, and the
notification icon on the status bar with "Ongoing" is also shown to
the user. Besides, I don't see any message from my customized log
message in the onDestroy() of this service.
 
//MyRunningService.java
 
public void onDestroy()
{
Log.e(TAG,"Oh!!MyRunningService was killed ");
}
//
 
The issues:
1. Why MyRunningService is always killed by the OOM? Can I prevent it
or can I detect the killing behavior by the service itself and restart
the service automatically with some good solution?
2. Is there any way to clean the notification icon as the service is
been killing ?
 
Thank you very much!
 
 


 

 Topic: About InputMethodService.switchInputMethod

Is the other input method actually enabled by the user?
 
Also you aren't clear where you are using this, but the API only works from
within the current input method. It does not work for applications.

I use this API in my IME service.
 
And I applied the solution from Issue 4604
(http://code.google.com/p/android/issues/detail?id=4604).
It could solve this problem.

 Topic: AlertDialog changes sequence of events

Brad Gies <rbgies@gmail.com> Jul 31 12:31AM -0700 ^

 
Why not just use the AlertDialog the way it is meant to be used? Even
though it's not modal, it looks modal the way it works anyway, and you
just need code a little differently and put all logic that happens after
the Dialog closes into the ButtonListeners.
 
What do you need to do that you think you can't accomplish using it
properly? For a Yes, No confirmation just setup a listener for the
positive and negative buttons (the same listener if you want).

I typically do something like this, this is largely pseudo-code:
 
 
enum SaveOperationState { CONFIRM, PERFORM, CANCEL }
 
save(SaveOperationState state)
{
switch (state)
{
case CONFIRM:
confirmDialog.show()
{
okButtonListenerMethod { save(PERFORM); }
cancelButtonListenerMethod { save(CANCEL); }
}
break;
 
case PEFROM:
doSave();
break;
 
case CANCEL:
doWhateverElse();
break;
}
}
 
 
 


 

 Topic: Adding custom column to contacts

WindowsNT <windowssnt@gmail.com> Jul 31 12:34AM -0700 ^

 
I am trying to add a custom data field to a contact, its UID is known.
 
I have not yet understood what exactly I should do. I saw and tried
other code , but to no success.
 
 
public static final String FORMALITY = "vnd.android.cursor.item/
some_text";
public void foo(ContentResolver cr)
{
ContentValues values = new ContentValues();
values.put(ContactsContract.Data.DATA1, "xyz");
String su = ContactsContract.Data.CONTACT_ID + "=" + uID + " AND " +
ContactsContract.Data.MIMETYPE + "= '" + FORMALITY + "'";
int mod =
cr.update(ContactsContract.Data.CONTENT_URI,values,su, null);
}
 
and "mod" is always 0.
 
What should I do ?
Thanks.
