[android-developers] Re: Does Google supply an interface?

[EboMike]

Can you elaborate? You're trying to prevent activity B from being
accessed before the password check in activity A has been successful?
I assume that activity B is any arbitrary activity?

[android-developers] Re: Any tools for analyzing API level compatibility in my Android code?

[EboMike]

Why don't you simply compile your app against API 4? (It's a setting
in the project properties). If you use any methods or classes that
don't exist yet, you will get compile errors.

Unless you're using reflection or hard-code flags, this should be a
good enough test. SHOULD, just off the top of my head.

[android-developers] Re: Displaying the ProgressDialog from the OpenGL thread.

[Lance Nanek]

Create an android.os.Handler subclass on the UI thread and pass that
to the renderer instead of a Runnable. It has methods for sending
messages and handling them. The renderer would send a message. The
subclass would handle it to show a dialog on the UI thread.

[android-developers] Re: Communicating between an app and a widget

[James W]

If you are talking about home screen AppWidgets, then yes it is
possible.

The place to get started is:

http://developer.android.com/guide/topics/appwidgets/index.html

Then have a look at some examples:

http://www.helloandroid.com/tutorials/days-xmas-widget-tutorial
http://nm-blog.sanid.com/2009/07/android-hellowidget-tutorial/

Basically as long as your AppWidgetProvider is part of the same
package and also declared in same Manifest of your main appilication,
then it has access to the same classes and can share its data.

I dont know if you can check whether an AppWidget is currently
visible, i.e. on the current pane of your Home Screen (e.g. because
you have 3 on vanilla android, 7 on HTC Sense, but it can certainly
know whether you have your AppWidget(s) active on at least one of your
panes.

Your widget can be updated directly by your application or via a
custom timer, or via the frameworks automatically scheduled updates.

And your widget can send info to your main application, e.g. process a
click to start the application, or access its data.

It's an interesting topic, good luck!

James

[android-developers] Any tools for analyzing API level compatibility in my Android code?

[CliveW]

I have developed an app for my customer at API level 5 (2.0) and
above, and set my minSDKVersion as 5. Now my customer would like to
know if it can be made backward compatible with API level 4 (1.6). I
have a vague idea which areas might not immediately be compatible
without doing some conditional code, but...

Does anyone know if there are any tools that can do a simple analysis
of my code and list for me any API calls I have that and their API
levels (preferably sorted, though I can do this if I can export the
info)?

This seems like a very useful tool if someone has it? (I'm not
expecting a full static code analysis, just API levels of all API
calls in a project)...

Thanks in advance for your comments...

[android-developers] Android 2.1 WebKit and applicationCache

[hansamann]

Hi all,

I am trying to use the Android 2.1 WebKit applicationCache but I
notice several differences to the iPhone 3/4(beta) implementation. Can
anyone tell me what the current status is and if it is in a usable
state?

Here are  my observations that I can share:

- initial caching works, but instead of sending a checking event first
as on the iPhone, it will just send out the progress events and then
the final cache event
- once you reload the page, it just shows the noupdate event. no
checking before that
- even if you update the manifest, it will not notice that. It seems
webkit on android does not check the manifest after the initial
caching.
- forcing an update with applicationCache.update() also does not work.

That leaves the current implementation in a pretty unusable state,
your users would presumably never get an updated cache once the inital
caching has run.

Has anyone else experience with this or knows when applicationCache is
supposed to be fixed/working?

Thanx a lot!
Sven

[android-developers] Re: OpenCore / Possible Issue w/ Streaming MP3 over HTTP?

[rktb]

Hi,

I was actually able to see the content length in the http response.
Here is a snippet from my log:
PVLOG:TID(0xe9bf8):Time=830:HttpParsingBasicObject::parseResponse()
file size = 5346201

But, yes, the auto-pause/auto-resume does indeed depend on whether or
not the content length is present in the header.

If you try to put the new OpenCORE code under your application, you
would need to write a new MIO [media input/output component] that
would dump the raw PCM data back to the java layer, which would then
use the AudioTrack API to render the data. But, I think that this
would be a bit involving.

I am still trying to think what other properties could be a factor.
Did you try:
- "smaller" content?
- lower bitrate content?

[android-developers] Re: Changing text color of a substring drawed in a text view.

[ArgBat]

Well, actually what i did is:

Get the text "Hello this is a text in
black color and (COLOR_RED_BEGIN)this is a text in red color.
(COLOR_RED_END)" and replace the (COLOR_RED_BEGIN) by
 and the (COLOR_RED_END) by .
Then call the text view setText like this:
setText(Html.fromHtml(convertedString)).

String originalText =  "Hello this is a text in
black color and (COLOR_RED_BEGIN)this is a text in red color.
(COLOR_RED_END)"

String convertedText = replacePlaceHolders(originalText);
textView.setText(Html.fromHtml(convertedString)).

Thanks to all for the non help. Taking into account the bad Android
documentation
I managed to do it.

[android-developers] Re: OpenCore / Possible Issue w/ Streaming MP3 over HTTP?

[SDS]

Hi Ravi,

Thank you kindly for your responses.

I've tried MP3 streams without ID3v2, but I should point out a
difference that may or may not be significant in the context of this
defect.  The HTTP headers for the MP3 streams were without a Content-
Length header.  In terms of the initial observations I reported, the
intermittent behavior is identical but without the increasing buffer %
callbacks.  I'm assuming this is expected, but I'll let you decide.

Regarding deployment of the latest code for OpenCORE with our
application, so that we can take advantage of your fix, what would be
involved from a development perspective, and how would you compare
that level of effort with us rolling our own HTTP streaming / MP3
decoding framework using native code?

[android-developers] Re: OpenCore / Possible Issue w/ Streaming MP3 over HTTP?

[rktb]

One thing to try is to encode a clip without Id3v2, and see the
behavior. That would reduce the probability of "insufficient data" by
a bit.

There's probably no way to do this. Once you open it the browser is a new,

Why can't you use WebView?

[android-developers] Re: Contribute to Android

[EboMike]

I'm afraid this is the wrong mailing list. You may want to check out
android-platform, that's where all the cool kids are who can help you
getting repo and git to work.

That said, you may want to re-read the instructions on
source.android.com - typically, everything should work once you follow
them. (However, please continue the thread on android-platform!).

[android-developers] Re: Upgrading 2009 I/O device from Donut (1.6) to Eclair (2.0/2.1)?

[Maps.Huge.Info (Maps API Guru)]

I think you're out of luck for now. Hopefully, an update will be
forthcoming however, it may be the device doesn't have enough memory
or CPU to handle 2.1, perhaps 2.2 is skinnier and that one will be
able to be ported to the MyTouch/ION. I have that device as well (got
it at IO 2009). Since I have AT&T, I've just forwarded my regular
phone number to the Droid for now, when the free deal runs out, I'll
go back to the ION. It's a nice phone and I like it a lot. The Droid
is ok too, just a bit too heavy for my personal taste.

[android-developers] Re: Android Browser debug question

[Maps.Huge.Info (Maps API Guru)]

What I would do first is try loading the page on a desktop with
Firefox and Firebug to make sure you have no obvious errors. If it
passes this test then try the next suggestion on your device.

I believe JavaScript errors from the browser will still show up in the
log. All you need is to dump your logs using the adb method as
described previously or one of the market apps like "Sendlog" (send
the log to yourself). Try that.

That's not possible, for patently obvious security reasons.

You can arrange to be the handler of a specific MIME type, but the user
will have to open the attachment manually, using whatever mail client
they are using. Or, if the user is willing to dedicate a separate email
account to you, you could fetch the messages yourself using a POP3/IMAP
client library (e.g., JavaMail).

That will only be possible if you are retrieving the email yourself via
a POP3/IMAP client library.

To be a little more clear, I would actually like 1 of the following
features:

1) Ideally, I would like every email scanned and the attachments
automatically picked up when they arrive if the meet the name and MIME
conditions
2) As a backup option, when reading an email I would like a menu item
that says "Send Attachments to AppName" or something like that.

That is not what happens on a call. The user is taken to whatever
activity they were in before the call. That could be the home screen,
but that could be something else.

Call finish() in your activity to return control to whatever activity is
prior to it on the stack.

[android-developers] Saving State of Media Player

[Andrew]

I wish to make an mp3 file play and loop. This works fine, but when
people hit home or back, after it finishes playing, it stops. I do
have setLooping(true). My other problem is that when I run the app
again while the music is still playing, a new instance of the app is
opened and it overlaps the music, how would I restore the running
state?

[android-developers] Re: How to fix hit area after scaling

[Jonathan]

Just in case anybody else wants to accomplish this, all you have to do
is override your child view's getHitRect method to account for your
parent view's scale transformation.

I'm not sure why the base view class doesn't do this automatically,
but I'm sure there is a reason.

This all sounds like a local Service to me. Open the db in onBind if
its not open. Let the service take care of how many Activities/
Services are bound and close the db in onUnbind.

Easy, simple everything you need is already there.

Or you can complicate things and reinvent singletons and counting how
many Activities and Services have references to your db object   ;P

[android-developers] method.getAnnotation( ) or method.isAnnotationPresent( ) not working

[Nehal]

Hello,
I am trying to use annotation - method.getAnnotation( ) or
method.isAnnotationPresent( ) and it is not working.

I am using eclipse emulator for 2.1 OS version with JDK 1.6. Following
is information about what I did. Please advise if I am doing something
wrong.

1) Added annotation type
public static final int METHOD_UNDEFINED = -1;

public @interface MethodInfo {
int id() default METHOD_UNDEFINED;
}

2) Added annotation for my method
final public static int METHOD_TESTMSG = 1;

@MethodInfo(id=METHOD_TESTMSG)
public void testMsg(String msg, int data1, boolean bool1) {
// code here
}

3) Now I am trying to find this method using annotation.
Method [] methodList = instanceClass.getDeclaredMethods();
for(int i=0; i< methodList.length; i++) {
if 
(methodList[i].isAnnotationPresent(MethodInfo.class)) {
// stuff here
}
}

[android-developers] Re: OpenCore / Possible Issue w/ Streaming MP3 over HTTP?

[rktb]

Hi,

I was able to reproduce the problem, and it is definitely timing
dependent. For the eclair codebase, I found a problem in OpenCORE's
mp3 parser node. That, however, has been fixed on the latest codebase
available at kernel.org.

Now, for applications that are being written for existing Android SDK
releases, I don't have a way out yet.

I don't use Eclipse for developing. It's only a webage with javascript
code.
To install Eclipse with Android and drivers takes a working day for me
because I
never worked with eclipse.

For me that looks like buying a tool shop but needing only a screw.

Is there no easier way to see javascript errors?

[android-developers] new interpreter for Android

[Andrei]

I am writing pure Java interpreter for Android
The language itself looks similar to JavaScript
The goal is to be able to write majority of apps on the Market
using scripts
It is in Alpha stage
The interpreter jar right now is 62 Kb
If you are interested to see how it works,
install apk from link below, it has examples of scripts and the src
Long press entry to see it's source
Please let me know what you think.
Thanks

http://gmlvsk.appspot.com/apk/IProgram.apk


This is just one of the examples.
It places 2 buttons on screen and changes text when you click them
-


var layout;
var button1, button2;
var cb1[], cb2[];
var counter1 = 0;
var counter2 = 0;

layout = LinearLayout.newObj();
layout.setMainView();

button1 = Button.newObj( "button1" );
button2 = Button.newObj( "button2" );

cb1["onClick"] = {
  counter1++;
  button1.setText( "clicked " + counter1 + " times" );
};
button1.setCallback( cb1 );

cb2["onClick"] = {
  counter2++;
  button2.setText( "clicked " + counter2 + " times" );
};
button2.setCallback( cb2 );

layout.addView( button1, LinearLayout.FILL, LinearLayout.WRAP );
layout.addView( button2, LinearLayout.FILL, LinearLayout.WRAP );

[android-developers] Credential Permission Error with HTC Sense

[polyclefsoftware]

I've released an app that uses the new AccountManager API to handle
authentication to Google App Engine as described in this thread:

http://groups.google.com/group/android-developers/browse_thread/thread/be16e3903442931b/63f01206f719effd

The first time the user attempts to log in, Android prompts them with
a system notification which reads:

"The listed applications are requesting permission to
access the Google App Engine login credentials for account
x...@gmail.com.  Do you wish to grant this permission?"

There are Allow/Deny buttons. Once the user presses "Allow", the
system setting is remembered, and login is seamless.

This works great on my Nexus and Droid, but upon release I'm getting
feedback from users on the HTC Desire and Incredible (both running HTC
Sense) that they get a force close when they hit "Allow", and the
Sense UI reboots. This is apparently not an exception occurring within
my app, because attempts to handle it from with the app and store the
stack trace for reporting are not working.

This sounds like a bug in the HTC Sense UI related to allowing access
to login credentials. Any advice on how to proceed? Is there a venue
for reporting bugs in HTC Sense?

Hi John,

Thanks for the information. I am aware of this, and have my Droid

[android-developers] Re: accessing sqlite db

[Christine]

1. where you open and close depends on your app. You can keep the db
open, and close and re-open in onResume and onPause, or you can open
and close before and after you access the db.

3. just retrieve the data that you need in the getView of your list
adapter, don't retrieve complete tables if you don't need them. Of
course, it depends on your app and on the size of the table whether
you want to keep the table in memory or not.

[android-developers] Re: Finishing Browser

[Serkan Ozel]

Setting the FLAG_ACTIVITY_CLEAR_TOP flag didn't work, Gyan.

I'm looking at other flags see if they work, an/or change the behavior
of the back button.

Back button does take me back to my application and ends the browser
only if I have one page to show but the reality is that I do have few
html pages, and back only works to take user back in the history.

Any more suggestions anyone?

I'll be working on it, I'll also post if I find anything new.

thanks

[android-developers] Re: Any body have an idea???

[Yahel]

First, please don't hijack other posts and change their subject.

As for your problem, it is probably very slow because of the size of
the image you are using(ie a photo from the gallery (2-5mpx) )
Since you are on a mobile device with a limited screen, you could
scale down the image to the display size say 320*480 using a
bitmapfactory and a matrix and postscale or any other method.

Then your code would have a lot less pixels to scramble.

Side note, but when you are trying to get speed any optimization
helps : make a variable out of  pixels.length - 1, that way the device
doesn't have to compute that number for the 5 millions pixels your
scrambling :)

You're right, but it looks like it cares about how you declare the
method.  If it looks like this:

public void callThisJavaMethod(Object x) { ...

I get null.  If it looks like this:

public void callThisJavaMethod(String x) { ...

I can get a string.  I'll just turn everything I care about into json,
works well enough.

[android-developers] Slow connection with Java NIO

[Kostya Vasilyev]

Hi,

I am experiencing slowness connecting to a Java NIO server running in my 
Android app.


The server code is fairly boilerplate:

- Create a listening server socket like this:

   ServerSocketChannel channel = ServerSocketChannel.open();
   channel.configureBlocking(false);
   ServerSocket socket = channel.socket();
   socket.setReuseAddress(true);
   socket.bind(isa);


- Register it with a selector

   mMainSelector = Selector.open();
   mMainAcceptKey = mServerChannel.register(mMainSelector,
   SelectionKey.OP_ACCEPT);

- Enter a processing loop

   while (mMainSelector.select(SELECTOR_TIMEOUT) {
 stuff getting the selected keys 
SocketChannel socketChannel = channel.accept();

Problem is, it takes about 1-3 seconds from the time the client begins 
to connect to when the above code gets to the last line (channel.accept()).


For read/write operations, the select() call returns immediately, which 
is expected.


Has anyone else seen this slowness in select() when accepting new 
connections?

Re: [android-developers] Finishing Browser

[Gyan]

I think back button would work depends on how you launch the intent.
must be part of the current task... FLAG_ACTIVITY_CLEAR_TOP

would do the trick I hope... If not, check on other flags, I'm not sure
about the flag - but I'm pretty sure you can make use of back button to come
back to ur app from the browser

I hopped that a button in the HTML displayed would close the browser
but it seems like the Android seems to ignore that.

[android-developers] How to determine current screen brightness?

[Markus]

I try to find a way to determine the current screen brightness.

Currently I use Settings.System.getInt(getContentResolver(),
Settings.System.SCREEN_BRIGHTNESS) but unfortunately the result is not
accurate when the phone is set to automatic brightness.

Thanks,
Markus

[android-developers] Finishing Browser

[Serkan Ozel]

Hello Guys,

I need to launch the Browser from my application (cannot do the
WebView - it has to be browser), and once I'm done with the browser,
is there a way to close the Browser and the user back to the
application programatically?

The problem is that user will probably press back or home keys to get
out of the browser - back key will not work, and home key will put
Browser and my app in the background.

I hopped that a button in the HTML displayed would close the browser
but it seems like the Android seems to ignore that.

Can anyone help?

Thanks

[android-developers] JetPlayer help

[Justin]

I've just started looking at JetPlayer and have (I think) created the
appropriate files needed in JetCreator (*.zip and *.jet files).  When
I test an implementation out, I get the following error in the logcat:

E/JET_JNI ( 1869): android_media_JetPlayer_queueSegment(): failed with
EAS error code -13

Any ideas what this means?

I followed the JetBoy example in the SDK.

Re: [android-developers] Re: Gallery elasticity at the ends

[Gyan]

Hey Nik... I got what you are trying to implement. If I'm not wrong its
called inertial scrolling. You can see google scoreboard app in the
market which has this already not exactly though. When that app came out
first I tried implementing the feel through layout animation.

The page contained empty space on either ends of the list as list items
without the ListSeperator which "onLoad"  scrolls back to the top or bottom
of the list - smooth and quick - as you let go of the touch. I had
implemented that through layout animation I bet there would be other
ways of doing it...

[android-developers] Re: Gallery elasticity at the ends

[Nik Bhattacharya]

I don't think I understand your suggestion Gyan.  I think you are
guiding me towards a Layout Animation which is not really what my
requirement is.

I am trying to signal to the user that they have reached the end of
the gallery via the fact that they try to drag past the first or last
item and instead of the gallery not moving at all, I want to have an
"elastic" feel at the end.  Again, very similar to the iPhone home
screen in which there is a little elastic effect when you go to the
last screen that you have it it has a little elasticity.

Re: [android-developers] Re: How to get selected items in a ListView (multi selection check boxes)? - URGENT PLZ

Have experienced this myself. implement a ListAdapter for the same and
handle ur items from there...

Additionally u can use onDataSetChanged to check for the multiple check and
uncheck options.i mean to say you can actually debug this at this
overridden method!

Not sure if google exposes this... but you can very well use ur facebook

content and use it... wont be any different; just that you will be using
your own sqlite DB for this and entropy will be less as its the contact book
contacts only

Turn on USB debugging on the phone, set it to allow external apps, plug it
in via USB, install the proper drivers, the run your app from Elipse - your
phone should be a target. Deploy it to your phone and debug as usual.

It worked for me, if you choose primitive data values. I don't have any
examples handy, as the last time I did that was for a consulting gig.

[android-developers] How to communicate from Javascript back to an app?

[James Moore]

I'm loading up a webview with some locally generated html and
javascript.  It makes calls to app methods just fine.

But what's the right way to get data from Javascript back to the
application?  It's simple to have javascript call app methods, but any
parameters specified in the call on the javascript side don't survive
the trip (I just get null in the app).  Gross hacks seem obvious (open
a url and encode the data in the url), but that can't be right.

Um ... unless the browser is programmed to put it's current URL in a result
and send it back, this isn't going to work.

Yes, SPP is supported.  In the BluetoothChat example, change to the

Read this on the blog of developer.android.com:

It'll tell you how to custom-handle back-key presses (and such) on 1.6

You can also download the SDK and install the docs component to have

[android-developers] How to access/call IBinder interface from ASE?

[Saravanan Bala]

I’m in the process of developing Lua/Python based Test harness automation
test suite for testing IBinder based message interaction.

How to achieve this? Is there any Lua/Python or any scripting sample or
examples provided?



Any help or pointers would be appreciated.

[android-developers] Auto-Process Email Attachments

[seguetester]

I have an Android app that I am working on that needs to get regular
data updates.  However, the only way that I will ever be able to
receive the data is via csv files arriving as email attachments.  I
wish that I could use a web service or something else more reliable;
however, this is the constraint that I am working with.

So, how can I build the functionality to monitor all incoming mail and
if I receive a message with a specifically named attachment that has
the expected MIME type, automatically save the attachment so that my
app can process it?

[android-developers] OpenGL drops triangles

[Leigh McRae]

Hello,

I am having a problem with what some of the triangles in my static 
meshes not being drawn.  The static meshes are created once and never 
touched again.  The class and all the data are marked final.  The 
triangles disappear based on view point.  The code all works on the 
BlackBerry and I have checked the data a couple of times.  I have 
managed to get a missing triangle on the screen and make a save game.  
This at least allows me to reload the game with the problem and try 
different things.


So I have disabled all 3d rendering except this mesh and the UI.  Here 
is what I have tried.

- switched to vbo
- switch to interlaced vertex buffers
- tried float instead of fixed.
- removed IntBuffer and used ByteBuffer
- disabled pretty much every state I could just before the rendering.  
Oddly enough disabling culling made one of two triangles appear.


Really at a lose here.  The game takes about 10min to load on the 
emulator and then it renders about half of everything but there are no 
errors.


I am using the following:

Android 2.0.1
Milestone/Droid

Here is my config that I use:

EGL_BUFFER_SIZE: 16
EGL_RED_SIZE: 5
EGL_GREEN_SIZE: 6
EGL_BLUE_SIZE: 5
EGL_ALPHA_SIZE: 0
EGL_DEPTH_SIZE: 24
EGL_STENCIL_SIZE: 8

[android-developers] Re: How to fix hit area after scaling

[Jonathan]

Right, thats what I am trying to figure out how to do. I currently
don't know how to separate a hit area from an actual view.

It would make sense to me if there was some function needed to be
called that would then figure out the new bounds of the views and
change their hit areas appropriately. I am calling invalidate on the
parent layout, but that doesn't seem to do anything to the views
themselves. I'll try calling it on each child and see if that makes a
difference.

I prefer instead something I saw recommended earlier on this list:
Create your library in its own Android project in Eclipse, but link
the library source directly into any other projects where you want to
use it.  On Windows, you have to use Eclipse's "link to source" option
in the Build Path.  On other platforms you can use a symlink to the
root package of your library source if you like.

With the export as jar option, you build the jar project, export it,
and then supposedly the other projects will use the new jar.
Unfortunately, what happens is that the other projects don't recognize
that the jar is updated, and won't until you: refresh the project,
remove the jar from the build path, and re-add it to the build path.

With linked source I just compile and it all works.

HTH,
Bobby

Re: [android-developers] Questions about is_restricted.

[Dmitri Plotnikov]

Hi Nthalk,

Restricted contacts are created by the Facebook sync adapter.  These
contacts are accessible to a whitelist of applications, which is specified
and enforced by Facebook.

The restricted contact API is private and I haven't heard of any plans to
open it up, which means that nobody (with the exception of Facebook) should
be using it at this point. In any case, the way it is implemented only
allows for a single restricted account.

Thank you,
- Dmitri

[android-developers] OpenCore / Possible Issue w/ Streaming MP3 over HTTP?

[SDS]

I’m experiencing an intermittent and very frustrating issue with
MediaPlayer on Android when streaming MP3 over HTTP.  I’ve done as
much research and debugging as I possibly can to try and find a
solution, but am coming up short.  I can’t find reference to this
issue anywhere, including b.android.com.

Essentially, what’s happening is MediaPlayer will not come out of the
preparing state.  The device is receiving audio data during this time,
as indicated by network sniffs and the MediaPlayer buffering callback
being invoked repeatedly with increasing percentage values, but
eventually the buffer appears to become full and stops receiving.
Because prepare() never returns, or more accurately when
prepareAsync() is used and the onPrepared callback is never invoked,
and neither the onError() nor onInfo() callbacks are invoked, the
application can neither call MediaPlayer.start() nor make any sort of
recovery.

Other notable observations:

-   The problem is intermittent, meaning that subsequent attempts to
play the exact same MP3 stream from the exact same server may exhibit
this behavior or not
-   The problem seems to be exasperated when the device is connected via
3G versus wifi
-   The problem occurs on different MP3’s encoded by different software
-   The problem occurs when streaming from different HTTP servers
-   The problem cannot be reproduced on any of the Android SDK emulators
-   The problem can be reproduced on the HTC Incredible, Verizon
Motorola DROID, and HTC Touch
-   When MediaPlayer successfully returns from the preparing state,
there is an info message (what=1, extra=44) received.  This info
message is not received during the problematic case.

Anyone ever experienced this, or even find a solution?

Thank you in advance.

[android-developers] Synchronous Display Calls

[karthik r]

Hi,

I'm new to android development. I'm developing an graphics application
and want to see the performance. I have a few questions in this regard
-

1) Is invalidate() called on a View after regular intervals by the
system itself? I mean does the display get updated on its own? Or are
we explicitly required to call invalidate()?
2) Is invalidate() an asynchronous call? If not, do we have any
synchronous display calls?

Please let me know in case anybody has any information regarding these
questions.

Thanks in advance!

I disagree.

Reverse engineering could let me implement a fix for a bug in an
application I bought legally when the original authors can't or won't
support it in the ways I need.
Reverse engineering can let me read their code to see if a security
hole exists, like them sharing my credit card information in
unapproved ways or calling a 1-900 number in the middle of the night.
Reverse engineering can let programmers read and learn from examples
of production quality code.

There are plenty of moral (as distinct from legal) uses for reverse
engineering.

I believe reverse engineering is still legal in the US under the DMCA,
but I also believe distributing tools whose primary purpose is to
enable removal of data obfuscation is illegal.  I don't know how that
law would apply to this example in the US, and of course local law
would apply for other parts of the world.

http://developer.android.com is the official SDK documentation. It is
not complete, but it is as complete as it gets.

onKeyDown() has existed for over two years, the same length of time as
the onKeyUp() that your re presently using. onKeyDown() exists in
Android 1.6.

[android-developers] Re: How to activate Droid received from Google w/ my own number

[EboMike]

Haha... I went through the same process, and it took the Verizon guys
over an hour to figure it out!

They need to give you a phone number for the Verizon employee number
services (you need a number based on which part of the US you're in).
Basically, the phone number you have is the kind that Verizon
employees get, and only certain tech support guys can touch them.

Once you call that number and explain your situation, it will take
them less than a minute to unhook your phone from that number. Then
you go back to the normal retail store and port your number.

(Of course, the retail guys could call that number for you - I had to
call myself since I went to the retail store when the employee number
services department was closed already, they have pretty lazy business
hours.)

[android-developers] how can I get the complete android documentation?

[Psyhclo]

Hi, I am Graduating in Computing Science, and my final project is a
complete research in Android's Platform, with a development of an
application. I would like to know how can I get the complete
documentation, beacause my research is very thorough, and I relly on
books and documentation. The current site I am reading about methods
and activities, etc is the Dev Guide on developer.android.com. I don't
know if is it complete there. But if you know, could you please show
me the link, or tell me how to get it?

Thank you very much.
