I understand that the lockpattern setting is a secure setting. But it

just changed this?!?

Is there a way to write secure

Not for ordinary SDK applications.

[android-developers] Re: Froyo-Problem: Calendar access

Whether or not it's wise to use unpublished Uri's, I'm sure tens of
thousands of android phone users are going to be annoyed if the
calendar data is no longer accessible.

Here's the system error:

ActivityThread: Failed to find provider info for calendar

Looking at the git source the URI appears not to have changed.

 Hi everybody,

 my app uses the internal calendar via the not officially, but in some

 all available calendars:

 Uri calendars = Uri.parse(content://calendar/calendars);
 Cursor managedCursor = act.managedQuery(calendars,
 projection,access_level300, null, null); /* selected */
 if (managedCursor.moveToFirst()) {
 etc.

 It works well with Android 1.5 to 2.1, but since Froyo there seems to
 be a problem. A Nexus user with Froyo gets force close and sent me a
 log with this line:

 05-24 18:55:04.308 E/AndroidRuntime( 1467): Caused by:

 that's the if-line.

 Can anybody give me a hint what Google has changed to the calendar since 2.1?

 I know the method to access the calendar was never official, but there
 was no alternative. And it's not a good user experience, when apps you
 have used before stopped working. And the (hobby) programmer cannot do
 anything, because calendar is not part of the SDK and I don't have a
 Nexus :-(

Re: [android-developers] Re: RTP stream video decoding

2010-05-25 Thread Andy Savage

Hi there,

I am working through this in a private discussion with another very helpful
user. Essentially it seems that at this stage the only way to get an RTP
stream to work is a couple of hacks:

A) Wrap it as an RTSP stream.
Basically need a client/server architecture, perhaps another little service
running in the background to buffer the RTP data (perhaps write to file?)
and then respond to appropriate RTSP commands.

I havn't tested this but theoretically it should work.

B) Write the data to two files. For example each file contains 1 second of
data. Write file, close file (thus the file gets timing information and lock
is released) open the file with mediaplayer and play. Meanwhile open another
file to write information to that. When mediaplayer finished with file 1,
get it to play file 2. Meanwhile write information to file 1 again. And keep
looping.

This is horribly resource intensive, but should produce an okay video (so I
hear). Although syncing information for this difficult (impossible?).

That's for streaming in. If your looking for information about streaming out
you should see the Sipdroid code VideoCamera.java where they implement a
'write to file', 'open file and stream' method. It produces a jerky but
reasonable video quality.

2010-05-25 Thread Andy Savage

Jez,

You might want to consider a pure RTSP implementation for what you want.
That should work fine for one way streaming. Android (atleast in 2.1)
handles this fine.

I understand some functionality relating to this was a little broken in
previous versions.

[android-developers] Weird activity launch behavior when started from other apps

2010-05-25 Thread Max

I have an application that contains several activities - call them A,
B, C and D. Normally the user will launch activity A, then go to
activity B, then C, then D. All activities have launchMode =
standard so that if the user switch to another app or return to home
screen, he can go back to where he left off by pressing the
application icon on launcher or home screen.

Most of the time the application works fine, but if the user start the
app from somewhere other than the launcher / home screen (e.g.
upgrading the app Android Market then press Open), the launch
behavior becomes very strange. Now if the user return to the home
screen, then press the application icon again, it will start a new
instance of activity A and put it on top of the stack. If the user
continue to navigate the app, the activity stack will become something
like A - B - C - A - B. I have verified this by running adb shell
dumpsys activity.

This behavior will persist until the application completely exits
(i.e. no more activities in the stack), until then the activities will
keep accumulating in the stack. As the activities are quite graphic
intensive, the application will run out of memory when there are ~15
levels of activities.

So... is there a way to prevent this behavior? I want the launcher
icon always get back to the activity where the user left off, or start
the default activity if the application wasn't running. I have tried
the various launch modes but seems none of them fits this description.

 * create a texture of type GL_TEXTURE_2D
 * set coordinates to fill full opengl rendering area
 * torendera frame update the texture with glTexSubImage2D or
 glTexImage2D function
 (more or less the same method that is used in vlc media player)

 With this method the performance is most terrible.. VGA rendering

 2)  rendering with canvas function Canvas.drawBitmap(int[] colors, int

 made a simple perfo test:
 * colors array was initialized in java code

 canvas.drawBitmap(colors, ... );
 mSurfaceHolder.unlockCanvasAndPost(canvas); in sequence

 Perfo is better than with opengl - v...@30fps uses up 40% of nexus one-

 3) Rendering with canvas function Canvas.drawBitmap(Bitmap bitmap,

 * in java code i do: mSurfaceHolder.lockCanvas(); nativeUpdate();
 canvas.drawBitmap(mybitmap, ... );

 * in native code i get value of a variable
 myrenderclass.mybitmap.mNativeBitmap via JNI
 * cast it to SkBitmap * pVideoBuffer
 * use pVideoBuffer-allocPixels();  pVideoBuffer-getPixels(); to
 get native pointer to memory (need to link to native android library
 libskia.so to get these functions)
 * copy or decode thevideoframe to this memory

 With this method i get only 10% cpu usage when doing v...@30fps... but
 lets face it - its a hack which may break in future

[android-developers] Re: Froyo-Problem: Calendar access

I have used the gacalendar data api / web access in early version of
Quick Addroid, my android app. The problem is, you need an internet
connection, if you want to enter a date, and, the biggest problem, you
have to ask the user for his password. That's bad, because a lot of
people don't like to give their password away to an app.

I think it's logical to use the calendar of the phone to add /
retrieve events. And it's a pity that Google doesn't publish a correct
way to do that.

[android-developers] Android Hardware Requirements

2010-05-25 Thread Andreas Frey

Hello,

is there any information about hardware requirements for an android
phone? I spent some time searching the web and this group but
unfortunately could not find anything useful.

Is there such an information, covering the following questions
- required screensize? (qvga [320x240] afaik)
- required/optional hardware components
  - bluetooth, wifi, compass, motion sensors, etc?

Any help is welcome.

It is not in there now, as the specs were apparently nailed down too
late for Froyo. I got the impression from various I|O mentions that it's
on target for Gingerbread, but I wouldn't bet the house on that.

[android-developers] Re: Participate in app promotion experiment

2010-05-25 Thread Jeff Knaggs


Here's another number my app, punch, is not free. At the beginning
of John's advertising experiment, the price was $1.69. I showed no
change in order rates after the first ~5000 impressions, and
subsequently lowered the price after ~1 to $0.99.  At that point
there was a consistent daily average uptick. That increase accounted
for 1.43% of the 420 click-throughs. Another number I'll share (that
really can only be applied to my app) is the cancel ratio: ~43%
cancelled (uninstalled/refunded).

Background on my app so you don't read too much into the numbers. I
wrote punch to get my feet wet on the whole process: from learning
Java (new to me), wanted to experiment with accelerometer for
potential use in a much more complicated project, to marketing
strategies. It's a very simple app --uses accelerometer: waits for non-
movement (kind of), tracks movement, detects non-movement (kind of),
reports acceleration and time of movement (kind of).


That said, I consider these facts as other confounding variables:
(1) only on market for approx 7 days before the experiment started.
(2) for most phone owners I predict this is, at most, a try-once game,
get-bored, rarely use again (if at all)
(3) there is a free game by somebody else with same basic
functionality, not as polished (not that mine is exactly polished
either). As an aside the free game has a fairly large download count
and a youtube video with a bunch of teens (?) playing it (over 11,000
views). There is an iphone game as well, with youtube video (over 7000
views).
(4) my app does put an admob banner up (some people may not like this
and uninstall?)
(5) I purposely do not put this in any of the game categories as part
of my personal marketing testing is to play around with naming and
categorization. punch is under applications:health with my Market
text implying one can use it regularly as part of a metric for
exercise.

[android-developers] Re: Any guidelines for handling the Headset and Bluetooth AVRC buttons in Froyo?

I notice that the music app does not release 'sole ownership' of the
intent even once it's UI exits, so anything in the background that
previously wanted to pick it up is out of luck. Which I did want to
do, as it happens.

Also that the previous owner doesn't have to release for another app
to be able to grab ownership.

On May 25, 2:41 am, Stefan skyntc...@gmail.com wrote:
 I am trying to figure out what is the correct (new) approach for
 handling of Intent.ACTION_MEDIA_BUTTON in Froyo. In pre 2.2 days we
 had to register a BroadcastReceiver (either permanently or at run-
 time) and the Media Button events would arrive (as long as no other
 application intercepts them and aborts the broadcast).

 Froyo seems to still somewhat support that model (at least for the
 wired headset), but it also introduces the
 registerMediaButtonEventReceiver, and
 unregisterMediaButtonEventReceiver  methods that seem to control the
 transport focus between applications.

 During my experiments, using registerMediaButtonEventReceiver does
 cause  both the bluetooth and the wired headset button presses to be
 routed to the application's broadcast receiver (the app gets the
 transport focus), but it looks like any change in the audio routing
 (for example  unplugging the headset) shits the focus back to the
 default media player.

 What is the correct way to handle that in Froyo? Do we have to detect
 the change in the audio routing and try to re-gain the focus?

 This is an issue that any 3rd party media player on the Android
 platform has to deal with, so I hope that a Google Engineer can
 provide some guidelines that we all can follow. Having a standard
 approach may make headset button controls a bit more predictable for
 the end users.

[android-developers] Can't we add shared libraries without use of android ndk tools

2010-05-25 Thread Karteek N

Hi all,
I have gone through android ndk tutorials.
But i am little confusing in Android.mk file as well as Application.mk file
so instead of that i used the following approach
I created a Test.java file which is having one native method.
i added the static{

System.loadLibrary(mylib);
}
By using javah -jni i generated Test.h and using that decleration i
implemented  a c file
And i compiled c file and generated the libmylib.so library.
But now my question is how to add this shared library to my android
application
I followed 2 approaches but all throwing exception that Library mylib not
founed.
1 In eclipse BuildPath-ConfigurebuildPath-Android2.1-native given the
path of my shared library
2 I copied shared library to /data/data/myprojectpackagenae/lib/
  and used the statement in my code as
   System.load(/data/data/mypackagename/lib/libmylib.so);

In above two cases it is throwing same exception

Where iam wrong?
Is it  procedure is wright?
Please help me

[android-developers] Re: Android Library Project

2010-05-25 Thread Mark Carter

For me, the biggest problem with the Android Library Project feature,
is that library source files are showing up multiple times (once for
the library project and then once for each project that uses that
library project) in:

1. The main source view
2. Call Hierarchy
3. Compiler warnings/errors

i.e. everything is duplicated making things much harder to manage.

(this is a bit more detail of what I wrote earlier - but essentially
the same problem)

[android-developers] Re: What happened to ADC3

2010-05-25 Thread Maps.Huge.Info (Maps API Guru)

I would guess that all the negative reactions from developers during
ADC2 has left a bad taste in Google's mouth. I was really amazed how
angry and caustic a large number of developers got during this
contest. In the end, I think it was counter productive and a waste of
developer and Google resources. A much better use was giving away
devices to the thousands of developers who qualified in the seeding
program.

If you look at what a contest such as ADC can do, it really alienates
virtually anyone who participates or in the case of ADC2, those that
couldn't participate because of the limitations and rules of the
contest. How many developers came away satisfied with the ADC?
Probably 30. The rest, which numbered in the thousands, were left
feeling like losers. That's the problem with contests such as ADC.
There are a few winners and lots and lots of losers.

On the other hand, giving away thousands of Droid and Nexus One
devices made many people feel good about Google and the developer
programs in general. There were still a lot of whiny ones who were
disgruntled because they didn't receive their device exactly two weeks
after being notified, but the vast majority were happily surprised and
delighted by the gift.

Ask yourself, which would you rather have: A one in 10,000 chance of
winning some large bit of money that requires three months of hard
work to participate or a guarantee of receiving $500 (in the form of a
device) for work already done. To me, there is no choice here, I'll
take the sure thing any day.

[android-developers] Stop Application Catch

2010-05-25 Thread adag

Hello All,

I have five screen in my application. While in performing one action
in fifth screen I encountered with Stop Application message. On which,
I am getting 3 times Stop Application msg box, which covers 3
previous screen and comes back to the first screen.

I understand I must have encountered with Error may be
IndexOutOfBoundException which I have not addressed it in my code. I
was wondering why it asks for extra 3 times Stop Application system
message. It is fine to display an Stop Application system message if
I encountered an error in any screen it should stop that particular
screen and should come to the next screen on. How can I trap/catch
such incidents not to occur in the consecutive screen.

Please provide your valuable suggestion.

If the above description is not clear at any place please let me know
that I be more clear to you.

Sincerely,
adjo

[android-developers] More about WakeLocks and Services

2010-05-25 Thread Evan Ruff

Hey all,

I was wondering if someone could help me clarify how I can created the
following:

1. My application uses AlarmManager to trigger an IntentService
2. IntentService gets a WakeLock
3. IntentService runs all the necessary code
4. IntentService releases WakeLock

For an IntentService, Is there a way to accomplish this without using
the BroadcastReciever Pattern, as created by Mark Murphy? It's my
understanding that the AlarmManager will invoke the Service directly,
so can I get a valid wake lock inside of the onHandleIntent method?

Thanks!

[android-developers] Re: Bluetooth question regarding observing a pairing

2010-05-25 Thread DonFrench

The BluetoothChat program is looking for a service with a specific
UUID and you need to change it to match the service you are looking
for. For the Serial Port Profile (SPP), the correct UUID is
0003--1000-8000-00805F9B34FB. However, unless something has
changed very recently, I do not believe that you can connect to
anything through the emulator. I think you will have to test your
code using an actual phone.

I highly doubt this since the Google Engineers are pretty adamant about

They're probably not going to help you continue to do so. Unfortunately this
is the risk you take in doing so.

In the meantime, consider doing a null check on that line and giving the

I have a TableLayout wrapped in a ScrollView and as the table expands

Well, since my app is free and I am not doing that as a business, I

 They're probably not going to help you continue to do so. Unfortunately this
 is the risk you take in doing so.

 In the meantime, consider doing a null check on that line and giving the
 user an error message. It's better than outright crashing.

Re: [android-developers] Re: Issue with setBuiltInZoomControls on HTC Incredible

2010-05-25 Thread Tom Coxon

Hi David,

I'm having this exact same problem too. My suspicion was that it was
related to UI customisation HTC did with the Incredible, so I emailed
HTC Tech Support a couple of nights ago, to find out, and they
suggested phoning the HTC Head Office in the UK (because Tech Support
can't give out that information). I've pretty much given up at this
point because I don't have the time to spend hours on the phone
explaining what the problem is to a dozen different people.

If anyone has been able to file a bug report or contact any HTC
software devs, please let us all know about it. :-)

My only solution for now has been to detect the phone model: if it's
the Incredible (Build.MODEL = ADR6300) disable built-in zooming, and
manually attach the zoom buttons. The downside is that this means
Incredible owners can't use pinch-zoom, which may or may not be
acceptable for your app. I'll send more specific implementation
details if you need it.

Regards,
Tom

I am facing a similar problem. My output after the test is ran is:

It seems that the JUnit framework is not able to find the tests inside

[android-developers] Semitransparent text over VideoView doesn't seem to render properly

2010-05-25 Thread Warren

I have a TextView with partial opacity (textColor=#55ff) over a
VideoView, all within a relative layout. I expect the text to be a
light white shading over the video. However, once the video starts
playing, the text looks a dark, dull gray. If I set the text to full
opacity, there is no issue and the text appears solid white.

My guess is that this is some type of optimization to prevent having
to re-alpha blend after every frame update, but I'm not sure. If so,
is there a way to disable it?

 Hi everybody,

 my app uses the internal calendar via the not officially, but in some

 It works well with Android 1.5 to 2.1, but since Froyo there seems to
 be a problem. A Nexus user with Froyo gets force close and sent me a
 log with this line:

 05-24 18:55:04.308 E/AndroidRuntime( 1467): Caused by:

 that's the if-line.

 Can anybody give me a hint what Google has changed to the calendar since 2.1?

 I know the method to access the calendar was never official, but there
 was no alternative. And it's not a good user experience, when apps you
 have used before stopped working. And the (hobby) programmer cannot do
 anything, because calendar is not part of the SDK and I don't have a
 Nexus :-(

 Greetings,
 Andreas

   
This is why Google begs, pleads and cajoles you not to use unpublished
APIs-- they will change without notice, which creates a bad user
experience and poisons perceptions of the whole platform.  When you use
an unpublished API, you are hurting every Android developer.

Google /needs/ to be able to change some things to move the platform
forward, and stuff that is undocumented is what they change.

If you can't find another way to get the functionality of an unpublished
API, the correct answer is to file a bug in the bug list requesting that
the functionality be officially provided.

From your description, it sounds like Google probably saw the app's
ability to access the calendar without going through the account log-in
page as a security flaw, and closed it.

[android-developers] Multitouch not working on Desire?

A user just told me that the built-in apps on his desire have working
multitouch but none of the downloadable ones are working, including
multitouch visible test and multitouch visualizer.  He said Dolphin HD
is working.

I'm a little confused.  Why would some apps get multiple touch points
and others not?  Is there something in the manifest that we need to
specify now for it?

Re: [android-developers] Re: Android Library Project

Yes, this is not great.

The problem is our need to compile the library code as part of the
main project, and Eclipse only really gives us access to linked source
folder (it's so much easier in Ant because we control the input to
javac). I'm not sure there are other ways, except than replacing the
Java builder with our own (and this is not something I want to do).

 Hello Garen,

 You should be able to make your existing Application class extend
 org.acra.CrashReportingApplication in replacement of extending Application.
 Just make sure to call super.onCreate() at the beginning of your own
 existing onCreate() override, and add other needed methods like getFormId()
 (required) and getCrashResources() (if you want to configure user
 notifications in acra v2).

 The limitation of this configuration system requiring to extend a custom
 Application class is when you need to use another lib which has the same
 requirement. As you wrote before, we can only extend one class. I might add
 some documentation later on how to enable crash reporting manually in your
 application class if you are in this very special case.

 Please contact me directly by email or file an issue on the project page if
 you still have problems with ACRA. We solved an issue with Mathias Lin today
 which occurred when the manifest doesn't use the android:versionName
 attribute. There's a new acra-2.0.2 version with the fix.

   Hello,

   I would like to introduce you to a library calledACRA(Application
   Crash Reporting for Android).http://acra.googlecode.com

   The goal of this library is to provide android applications developers
   with a tool to let their applications send them crash reports the
   easiest possible way.

   One of the main issue when implementing crash reporting tools is...
   where do I send my reports ?ACRAsolves this problem with a simple
   solution : reports are sent to a Google Docs Form ! So you don't need
   to code your own reports receiver scripts and you don't have to find
   dedicated hosting for that... let's use Google's servers ! :)

   A first version ofACRAhas been successfully used in a few apps
   already on the market, and we are now preparing to publish a v2 which
   allows developers to replace the annoying force close dialog with
   fully configurable notification systems :
   * Silent : the user experience is not altered compared to standard
   android apps. The force close dialog is displayed, butACRAtries to
   send a report. If it fails, reports will be sent on application
   restart in a separate Thread.
   * Toast notification to inform the user that a crash report has been
   sent (and you may add that it can be disabled in the preferences
   screen)
   * Status bar notification which leads to a dialog asking the user if
   he's ok to send a report. You can even add an input field to let him
   comment the issue.

   We are now looking for devs who would like to test the library and
   it's different notification modes. All the information, screenshots
   and step-by-step usage guide are available in that Wiki page :
 http://code.google.com/p/acra/wiki/ACRAHowTo2

   Devs who would like to use the v1 and it's basic (but working)
   functionnality can follow this link :

Actually, he's seeking an answer to a question that I couldn't answer
(at least not without more experimentation).

My implementation uses a BroadcastReceiver to get the WakeLock and start
the WakefulIntentService.

The OP is wondering if we can skip the BroadcastReceiver, and just have
the AlarmManager invoke an IntentService directly, with the
IntentService grabbing the WakeLock in onStartCommand().

Personally, I am nervous that this might be too late, and there might be
a gap where there's no WakeLock in force, so the phone may fall asleep.
However, I don't know that for certain.

Has anyone experimented with WakeLocks and IntentServices, besides my
WakefulIntentService?

One thing that makes things slightly easier is to uncheck the Builders -
Java Builder of the Library project. This means that compiler
errors/warnings will not be duplicated. You still need to be sure you are
editing the code from MyApp/MyLibrary rather than MyLibrary.

This doesn't help the call hierarchy problem though.

Another option is just to use resource-only libraries and live with
replicating the java code in the top level apps.

On 25 May 2010 19:49, Xavier Ducrohet x...@android.com wrote:

Yes, this is not great.

The problem is our need to compile the library code as part of the
main project, and Eclipse only really gives us access to linked source
folder (it's so much easier in Ant because we control the input to
javac). I'm not sure there are other ways, except than replacing the
Java builder with our own (and this is not something I want to do).

3. Compiler warnings/errors

i.e. everything is duplicated making things much harder to manage.

In the interests of keeping things together here is the link 
http://groups.google.com/group/android-developers/browse_thread/thread/f963e8f7ac35b75b 
for my thread I started in the developers thread just a few days ago 
related to this.


I will file a bug request sometime soon unless anybody else can shed 
any light (although I don't know if there will be much attention paid 
to it). It is more a feature enhancement than a bug I think, but 
it's definitely causing me difficulty.


The functionality to decode RTP streams is already built into OpenCore 
but unfortunately you can't pass an SDP file to the MediaPlayer 
(OpenCore Wrapper) unless it contains an RTSP stream link inside it. 
This is a bit dumb really... what's the point in passing an SDP file 
in that case? but ah.


RTSP is not a stream. It's a command and control protocol. The SDP 
announcement(s)

is the payload describing the media to be streamed. SIP also uses SDP.

The flow is:
RTSP/PLAY-- client
RTSP/SDP  - client
RTP--- client

Where you just listen for the UDP RTP packets on the port the SDP
announcement told you listen on.

Mike



There seems to be a limitation that means that it will only accept SDP 
information with RTP streams inside if it gets them from the RTSP 
stream (e.g. it gets this information from SETUP in the RTSP protocal).


Thus far it seems the only solution is to dump the RTP packets to a 
file (periodically close the file and write a new one) then 
periodically open these files in mediaplayer. A pretty ugly hack really!

Hi everyone,

I need a little bit of help from some experts out there.

Currently I am developing an application that will stream video using RTP
and SIP. I have this mostly working with audio working fine both ways using
Java (and native) codecs. I can stream out video also from the camera to a
windows client.

The problem comes from when I want to receive and decode the video on the
android platform. I understand at this stage that Mediaplayer only supports
RTSP streams. Ironically it does what I need (by getting the SDP information
from using RTSP SETUP call and using that RTP/UDP information to receive the
stream). But I can't seem to access this functionality, all it takes as
input is a RTSP url. If you are unfamiliar the difference between RTSP using
RTP and SIP using RTP. You can read about the differences
herehttp://www.cs.columbia.edu/~hgs/rtsp/faq.html#rtsp_sip
 


Oh, ok... you've at least read Henning's faq. Sorry for the previous
post.


.

What I need to do is take an RTP stream encoded with h.263-1998 and somehow
pass it to the mediaplayer (or even a lower level api if somebody can
provide an example).

The only way I can think around this is to write another service
to receive the RTP stream and provide an RTSP interface... but this is a
really ugly solution.
 


Yeah, you might be stuck with a B2BUA. But RTSP is *really* simple,
so setting up a local listener and pasting them together shouldn't be
*that* horrible of a hack if it comes to that.

I would really appreciate if anybody could offer any help with this.

[android-developers] Android 2.2 MediaPlayer Woes

2010-05-25 Thread Brad

I have an app that uses multiple media players to play overlapping
sounds.  Each time I play a new sound the following actions are
performed:

- reset
- setDataSource
- prepare
- setLooping
- setVolume
- start

Up until 2.2 everything worked fine, now the first media player sounds
fine, but when I start the second media player the sound is garbled
and I get the following messages in the console:

E/MediaPlayer(  449): error (1, -2147483648)
E/MediaPlayer(  449): Error (1,-2147483648)

and later

E/MediaPlayer(  449): Error (-38,0)
E/MediaPlayer(  449): Error (-38,0)

I know the standard recommendation is to use a SoundPool in this case,
but it doesn't work for me because I need to know when each sound has
finished playing.  Also my samples are very large and SoundPool seems
geared toward smaller sound clips.

Any idea what may have changed to cause this new behavior?  Any ideas
for possible workarounds? Thanks!

The system message will occur when your code crashes. If the system
message is appearing four times, then your code is crashing four times.

Use adb logcat, DDMS, or the DDMS perspective in Eclipse to fix the bug.
Then, the system message will go away.

Re: [android-developers] Re: Client server setup in android

2010-05-25 Thread Frank Weiss

Hi santha,

Please note that REST has much more to do with the HTTP method (GET, POST,
PUT, DELETE, etc.) and the URI than with the data serialization, such as
JSON and XML.

For many simple client-to-server data transfers, you can use the query
parameters instead of REST.

JSON and XML are often a subjective developer choice or dictated by an
existing web service. JSON is less verbose. XML can be transformed with
technologies such as XSLT. For HTML web clients, JSON is often the
serialization of choice because it maps directly to a Javascript object
graph. However, there are several Java libraries that will
serialize/deserialize JSON to Java object graphs.

Tell me if I am wrong, but Google tells us, there is a content
provider for calendar:

http://developer.android.com/guide/topics/providers/content-providers.html

There you can read:

Similarly, the URIs for the table of recent phone calls and the table
of calendar entries are:

android.provider.CallLog.Calls.CONTENT_URI
android.provider.Calendar.CONTENT_URI

There is even a permission for read and for write to the calendar, so
I think

 From your description, it sounds like Google probably saw the app's
 ability to access the calendar without going through the account log-in
 page as a security flaw, and closed it.

you are wrong. The user accepts that I work with his calendar, the
same way it's no security hole if I work with his emails, after the
app requests permission on install and is granted permission.

[android-developers] ListView and ListAdapter

2010-05-25 Thread John Gaby

I am trying to use ListView and ListAdapter.  If I create a simple
Android project and add a ListView as the content view, and set it's
adapter to my adapter based on ListAdapter, everything seems to work.
My ListAdapter's 'getCount' is called, and I return 3, my
'getViewTypeCount' is called and I return 1, my 'getItemType' is
called and I return 0, and for each item, my 'getView' is called and I
return a TextView.  Everything works, and the list is displayed with 3
items.

Now if I try and do the same thing in a more complicated environment,
it does not work.  My 'getCount', 'getViewTypeCount' and 'getItemType'
methods are called, but the 'getView' method is never called and the
ListView appears empty.

Now I know that I must be doing something wrong in the more
complicated case, but I cannot see what it is. The code is really too
involved to post here, but I was hoping that someone could give me
some ideas as to why my 'getView' is never called even though I return
3 from my 'getCount' method.

Thanks.

 As far as my understanding goes, I have to use a Service. Each

 The problem is that the service process can be killed at almost any

 Service. How is the set of open files supposed to persist an eventual

Android Market. It uses two input-lines (EditText) and has always
worked well until I updated my Nexus One to Android 2.2.

When I would touch the input line, the soft keypad would pop-up
automatically, lift up the focused input line into view, and then I
would type in my numbers...no problems. But when I updated to Android
2.2, the soft keypad doesn't lift the focused input line far enough
and it's only half in view. Then when I scroll down to the next input
line, it doesn't lift up either and it's only about 1/4 of the way
into view. Another problem is that, sometimes, when I go back and
forth between the two input lines and then try to enter numbers - the
numbers don't appear but they do when I scroll left. Hard to explain
exactly what is happening but something strange is going on there that
didn't happen under my Android 2.1 and other lower versions.

I even tried to change some input line (EditText) statements in my
code and also tried to change the way the soft keypad would 'pad' the
view to the top but things still didn't work after I recompiled.
(android:windowSoftInputMode and android:inputType)

I also wonder if they made the soft keypad in 2.2 a little bigger in
height (na - that's crazy).

Anyway, any help would be appreciated. Does anybody out there with 2.2
mess with an app that has input lines where their softkeypad has to
move the input line up into view - does it work for you?
