[android-developers] Re-using the Android Call Log / Contacts and sms capabilities.

[Android Development]

Hello developers/community.

I am making an internet telephony application based on a proprietary
protocol which connects to a web server for call setup.

As with other telephony applications this app also has three basic
requirements: The need for a call log, a contact book and the ability to
send/receive messages.

One option is for me to develop all these three capabilities from the
scratch. Another possibility is to leverage upon the built-in capabilities
of android and tie them up to my application using content resolvers and
Intents.

Let me explain my requirements below, and I welcome your comments regarding
their technical feasibility:

*A)) Call Log: *

I would like to maintain the call log of my application with the android
call log. This will make sure that the user has one view of all the calls
that were made (cellular or internet). Is there a way to read/write/delete
from the call log application from android? I believe this can be done using
content resolvers.

>From the call log, if the user wishes to call back a customer (internet
customer in my case) , then I wish to provide the user with an Intent
Chooser. If the user selects by application, then the call will be made from
my application and not a cellular call. How do I achieve this behavior ?

If I listen to the ACTION_CALL intent, will my application be available in
the intent chooser ? Or will android try to initiate a cellular call by
default?

*B)) Contact Book:*
*
*
The customers can save the internet user's address in the contact book.
There is an entry of a CUSTOM_PROTOCOL in the contact book of android. That
is where the address of the user can be stored who is using my application.
We already have choices of Yahoo, Gtalk and Skype in the contact book.
Similarly, we can also have a custom protocol entry over there. But this is
only half the issue.

When the user selects the address of the custom protocol from the contact
book, I wish to display a pop-up listing my application (maybe I can listen
to the intent which is emitted). Now, if the user selects my application
from the pop-up, I will make a call over the internet instead of the
cellular world (my broadcast receiver will gain control).

Again, I am not sure whether the above is possible and android will display
the intent chooser from the contact book if my custom protocol field is
selected.

*C)) SMS capabilities:*

When the user composes a SMS and tries to send it, I wish to intercept the
outgoing SMS and provide the user a choice - to send the SMS using my
application,or from android's native capabilities (GSM-SMS). I believe it is
possible to listen to outgoing messages by registering a content observer on
the SMS content resolver URI.

However, I would like to know whether an INTENT is fired when the user tries
to send a message ? It would make life much easier.

Secondly, I want to re-use the android SMS storage for the messages received
from my custom protocol over the internet. I wish to write to the android
sms database (using its content resolver) for this.

Thanks in advance

With Regards

Indodroid.

[android-developers] Dev phone linux (and Windows)

[Davide]

Hi,

as company we want buy some android phone. The phone will be used for
developers to test and run applications.

Which phone are the best for this?

We have both Windows and Linux system, which android mobile will work
on both system for developing?
What I mean is that adb and eclipse can connect to the phone, and,
when possible that the phone
uses the computer network.

For example I have tested the htc wildfire and I have seen  that in
windows the default usb drivers does
not works with adb and eclipse. Only work installing htc software ,
but this is only for windows.

Thanks in advance for the help!

[android-developers] Re: Dynamic images slide show along with context menu and about smooth swipe event..Urgent suggestion/Idea needed..

[sunrises]

Hi,thanks for your suggestions
I have a lot of images to show as slide show,I did it using thread
concepts in which a slide show thread continuously updates the UI for
every 10 seconds(time interval between images) using handler, when
user touches and moves his finger(horizontally towards left/right ) on
the screen then the slide show should forward/backward images, I tried
to accomplish it by implementing onTouch() method in OnTouchListener .
But I did not get smooth swipe at all..please correct me...here is my
code..
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
firstX=event.getX();//firstX is instance variable
break;
case MotionEvent.ACTION_MOVE:
  if(firstX - event.getX() > SWIPE_DISTANCE){ //
SWIPE_DISTANCE value 120)
/*  here the code to show the next
image by updating UI using handler and stops the slide show
   thread for 10 secs after that the
slide show thread will starts again*/
 }else if( event.getX()-firstX  >
SWIPE_DISTANCE){
/*  here the code to show the previous image by
updating UI using handler and stops the slide show
thread for 10 secs after that the
slide show thread will starts again*/
   }
}
}//end of method

[android-developers] Re: Chilling news: Oracle sues Google over Android

[gosh]

The Irony of Java's success on the device UI via Android

There's lots of irony in the successful use of the Java 'language'
within the phenomena that the Android OS has become. E.g.
Java began life at Sun as Oak which was meant to be a language for
small devices up to set-top boxes. It went on at Sun to become a whole
'platform' of APIs too, that technically challenged other OS's such as
Windows, and whole server stacks of all persuasions - to the point
where Microsoft had to then develop the .Net platform to stay ahead in
the game. (I use that unfolding Java scenario as the ultimate case of
'scope creep' to my students).
Ultimately Java made its name and market running server-side, away
from user-interfaces. Desktop-wise, Swing was too much too late.
Mobile-wise ME was too limited, too rigid, too early.
The Android user UI classes and widgets (which are nothing like Swing
or AWT - I know, as I tried to convert lots of swing code to them -
and a total rewrite was required), have hit a sweet-spot on mobile
devices, just when processing power, interactivity and screen
presentation can provide a 'user experience', that the modern user now
demands of their daily devices.
Java the language, via Android the GUI  OS, has finally fulfilled
Oak's original goal from way-back, of running on small devices and
attracting a huge market there-on, in the process. That's Irony with a
capital 'I'.

As for the originality of byte-code and virtual machines - the P-
System was doing all that with p-code, back in the days of 8-bit
micros, before some fool at IBM chose MD-DOS over it as their standard
OS for the new 16-bit Intel processor - and an eon before the
invention of 'software patents' themselves.

[android-developers] Getting current radio state in my application

[Webgenius]

Hi,

How do I check the current radio state in my application? I'm
interested in the RadioState defined in CommandsInterface.

My application checks for the current radio state: The state would be
RADIO_OFF when Airplane mode is active, and NV_READY when radio us up.

Is there any other way to get the status of the fields that I'm
looking for?

Re: [android-developers] Re: AT&T Samsung Captivate > mExternalStorageAvailable == false;

[Dianne Hackborn]

For what it stands, the platform today does not support more than one
external storage directory.  Manufacturers who are adding an SD card in
addition to internal "external" storage are adding features that
applications written against the standard platform are not expected to
support -- they should be able to rely on there being one external storage
directory with one state and not need to care about others.

I realize this doesn't help when users are asking for support for whatever
extra stuff a manufacturer has added...  but please look at it as going
above and beyond the call of duty. :}  And since this is not a part of the
standard platform, unfortunately you'll find the way this stuff works to
vary across manufacturers.

It's possible there will be a standard API for this in the future...  but to
be honest, it is hard for me to imagine dealing with multiple external
storage locations as resulting in a decent user experience, so it may not
happen.  Just causing the user have to be aware that they have some pictures
in their internal storage and some in the external SD card, and how much
space they have on each, and what to do if one is full...  yuck.

I think what people generally do is add analytics to their app to track
unique installs then compare that to how many Google Checkout orders you
get. Or something along those lines.

[android-developers] MenuItem with Spanned elements in their titles

[Greg Giacovelli]

Hi I was just trying something and realized this doesn't seem possible
due to the debugging code in the android OS.

I register a context menu on an AdapterView, via
registerContextMenu(mAdapterView), and then implement the
onCreateContextMenu, like this:

CharSequence title = context.getString(R.string.txt, userName);
title = Html.fromHtml((String) title);
MenuItem item = menu.add(ContextMenu.NONE, ContextMenu.NONE,
ContextMenu.NONE, title);

The context menu displays correctly, however when it is clicked I get
an illegalArgumentException from the EventLog class when it tries to
print out the condensedTitle.

So I have found without setting the condensedTitle explicitly to
something that is a String this occurs. Why is this marked as a
CharSequence if it cannot handle it?

[android-developers] Re: AT&T Samsung Captivate > mExternalStorageAvailable == false;

[john brown]

I do appreciate the comments and suggestions. They give me new things
to try.

The good news it the app is working on the Samsung SGH-i897 now. The
bad news is I do not know why. Here is what happened:

1) I hard coded "/sdcard/sd" rather than getting the path
programatically. (I did not have much time.)
2) I got the same error, something like "path not found"
3) I went back into the code and removed the hard coded path.
4) I added a System.out.println("ext storage is " + myPathVariable)
5) I ran it one more time just to check what the output path was
again.
6) It ran, no errors.
7) The output was "ext storage is /sdcard/Android/data/lms/mp"

That is the same path it printed when it got the error. A satisfactory
explanation would be that my memory is wrong or I did not type what I
thought I typed, but I cannot find the error.

I do not know why. But it is working. :>)

I will test some more tomorrow.
I will stop using - Environment.getExternalStorageState()
I will try - Environment.getExternalStoragePublicDirectory()

Right now I am thinking it has more to do with the phase of the moon
than with concrete facts. Like it does not work Friday through
Wednesday. But it does work on Thursday!

Again thanks for all the help. John Brown

A substantial percentage of questions posted to the android tag in
StackOverflow get at least one answer, within 24 hours:

http://stackoverflow.com/questions/tagged/android

Of course, whether any given question will get answered depends a lot
on the nature of the question. You neglected to provide us any
information about what sort of "fundamental issues of Android
programming" you are experiencing. There may be better resources for
certain classes of problems (e.g., NDK programming, firmware
programming).

[android-developers] Help Wanted!

[Ahmad]

I have been very frustrated with some fundamental issues of Android
programming. It seems to me that reliable knowledge about Android is
both scare volatile. I had imagined that Google people have a vested
interest in nurturing the developers aspiration to learn.

Alas, many of my questions have remained unanswered.

So I am looking for pointers from the good souls visiting here. What's
the best way to unblock some of my problems with Android? Where should
I post my question so that it would be more likely to get an answer.

I am even willing to hire a good soul who would assist me about an
hour a week. I am sure that just getting some of my key questions
answered will get me very far.

I live near Google in the Peninsula. If you feel like helping me and
at the same time making a bit of money, please contact me.

I really appreciate any help (even sympathy!) that anyone can  give me
over here!

best,

Ahmad

You are quite right "this is unlikely to be easy", and actually I have
tried to go this way before posting the question here.
There must be a better way.
I am going to look into Android's sources to find out if I can
overwrite something in TextView to make it work.
Thanks for the ideas Mark.

[android-developers] Re: How to compile/run JUnit 4 tests in Android?

[Eric]

Ah, thank you very much.  That bit of information about the test
runner helped tremendously.  Believe it or not, I did some fairly
exhaustive searches on Google regarding this issue, but I always
referenced Android in some way. Had I just search on running JU 4 on
JU 3, I may have found the same answer you did.  I truly appreciate
your assistance, and I'll try out your suggestion right now.

Thank You,
Eric

[android-developers] Re: How to compile/run JUnit 4 tests in Android?

[A. Elk]

I have never tried to use vanilla JUnit 4 running under Android. I am
not absolutely certain, but I predict that it won't work. To run any
test, you need to use InstrumentationTestRunner, and it assumes JUnit
3, which is substantially different from JUnit 4. However, the
documentation for JUnit 4 says:

You make your JUnit 4 test classes accessible to a TestRunner designed
to work with earlier versions of JUnit, declare a static method suite
that returns a test.

public static junit.framework.Test suite() {
return new JUnit4TestAdapter(Example.class);
}

I'd look at the Javadoc for junit.framework.*. When I Googled it, I
saw that it included JUnit4TestAdapter. Better yet, search for help on
running JUnit 4 tests under JUnit 3. InstrumentationTestRunner is
designed to work with earlier versions of JUnit, so anything that can
convert a JUnit 4 suite to JUnit 3 should work in Android. That the
documentation for JUnit 4 includes instructions for running JUnit 4
suites under an earlier test runner implies that it's a known
situation, so I assume somebody else has written about it. Seems like
nobody else writing for Android has encountered it (or bothered to
reply), but at least for "vanilla" tests someone probably has done
something.

Sorry I can't help you any more.

PS - I notice that the main differences between JUnit 3 and JUnit 4
tests are a) JUnit 3 denotes a test suite by subclassing
junit.framework.TestCase (JUnit 4 has no such requirement) b) JUnit 3
test methods are denoted by the string "test" as the prefix of the
method name, while JUnit 4 uses the @Test annotation. It doesn't seem
to me that there are any other substantial differences, but as I have
already said, I am not a JUnit 4 expert.

Override onTouchEvent(), find the coordinates of the screen tap, then
run a bunch of text metric calculations to try to determine what word
is at those coordinates. This is unlikely to be easy.

I'm not strong enough with my DOM events to know if you could find out
the clicked-upon word if you put the text into a WebView instead of a
TextView.

Bear in mind that your current design assumes the existence of a
touchscreen. It remains to be seen how long that assumption will hold
true. Google TV, for example, might be more pointer-centric.

[android-developers] Re: OutOfResourcesException when using GLSurfaceView and VideoView

[Indicator Veritatis]

Since it varies from device to device, where is it documented for each
device? Or which Android API will return this information?

Since per application memory sounds like an OS issue, I would expect
it in the android.os package, but I am not seeing it there.

[android-developers] Re: Is anyone's active install % dropping like a rock lately?

[Indicator Veritatis]

In introductory economics classes, whether at high school or
undergraduate level, we are taught to think of buyers and sellers as
perfectly rational. In good classes, we are told that this is only an
approximation. Unfortunately, people tend to soon forget that it is
only an approximation. Those of us who go on to study pricing in
business school learn just how poor an approximation it really is, as
your anecdote confirms!

That said, I can't help but wonder if the phenomenon you report is due
primarily to two factors: 1) when they are sold the expensive phone
and plan, one of the key selling points is "there are lots of free
apps" 2) after spending that much on the phone and realizing how much
they pay per month, they suffer from "buyer's remorse", which
encourages their hope to get something for free even more; they figure
they have already "paid their dues".

Re: [android-developers] Re: Starting an Activity from a callback class

[Priyank Maiya]

I was able to fix the problem.
The issue was that i did not have the context instance in my callback class.

I created a constructor where I got the context from the service class.

Using that I was able to call the application activity class.
Also I had to use
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); for starting the task..

This was my constructor in the callback class
private VServiceCallBack(Context iContext)
{
context = iContext;
}

And according to the arguments received,

{
Intent appView = new Intent(context, AppView.class);
appView .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(appView );
}

Sorry for the confusion, and thanks for the help..

[android-developers] Re: OutOfResourcesException when using GLSurfaceView and VideoView

Good info. But he should also keep track of the direct buffers he
allocates w/ OpenGL: for as the docs warn: "A direct buffer will try
its best to take advantage of native memory APIs and it may not stay
in the Java heap, thus it is not affected by garbage collection."

(from http://developer.android.com/reference/java/nio/Buffer.html).

Now if only the same doc were as informative about how to deallocate
it in the case it is not affected by garbage collection:(

[android-developers] Re: How to compile/run JUnit 4 tests in Android?

[Eric]

I absolutely want my POJO JUnit 4 tests running on the Android
emulator VM, even if they do not reference Android APIs.  The reason
for this is fairly clear.  Android has a different implementation of
the base Java APIs, and it uses a special VM, so I want to know that
all of the shared code I will take advantage of beneath the Android UI
layer will run without fail on the emulator.

I hate to say this, but I am _still_ confused as to whether or not
this is possible.  Your eloquent answer didn't seem to answer the
question specifically.  Quite simply, is it even possible to run POJO
JUnit 4 test suites on the Android device itself, and if so, what is
the best/quickest way to achieve this from a configuration standpoint
in Eclipse?

AFAIK, you cannot programmatically set the layout folder.

1024x600 is not a supported screen resolution at this time. It seems
likely that the upcoming Gingerbread release will add support for this
resolution or similar ones. At that point, you should receive official
instructions on how to best support such resolutions.

In the meantime, use two different names for the layouts, use
DisplayMetrics to figure out your screen size, and choose which layout
to load by name.

[android-developers] enable/dissable fullscreen for lifetime of the app?

[Moto]

Currently my application allows the user to set the application to run
in full screen.  I than check in every activity at onCreate() if the
user has set to make the app run in full screen.  Is there a better
way to do this?  I have many other settings that I do and I find this
method a little bad in terms of code design.

Is there a way to set full screen for the lifetime of app or until I
set it back to not full screen?

One way to do it would be to have a custom Activity class that does
these checks and all my activities can just implement it?  would that
be slow is it recommended?

Thanks!

[android-developers] Re: Optimizing image processing algorithms for Android

[Indicator Veritatis]

This sounds all find and good, but I still haven't heard anything
about the far more common cause of delay: the garbage collector
locking up the thread or pre-empting the CPU. Or has Amit already
solved this problem?

As for alignment, OpenGL as implemented by JSR-239 (therefore
available on Android) solves this problem by using the JSR-239
java.nio Buffer classes. If you use one of these, you are guaranteed
word-alignment on the ARM.

NB: I say "jsr-239 java.nio" because there may be subtle
implementation differences between those and the original java.nio
classes. For example, JSR-239 does not expect flip() to be useful, nor
is supporting Mark required.

NB: the online docs for Android's java.nio do not mention alignment: I
found this info in one of the OpenGL ES specs (I forget which one): I
forget whether or not the Buffer must be allocated Direct or not to
get this benefit.

AFAIK, you will need to write custom firmware to get access to this
information. I am not aware of this information being available to SDK
or NDK applications. Sorry!

Yes. You will need to define your own layout for the rows. Depending
on your choice of adapter you may also need to subclass the adapter
class to handle mapping your data into those rows.

[android-developers] Regarding Storing of data in the database in android.

[AAJ]

Hello,
I am working on some sample programs, where i have to take the value
from the user and store it in the database. I have used DroidDraw to
create the XML code for UI.For now, I have just started with a
textbox. So, I have to take the value from this textbox and store it
in a database. I am using SQlite browser to create tables. I read in
some forums, that one way of doing this -
1. Copy the db file in the asset folder of the android project and use
the AssetManager class. But i am not able to figure out how to use the
asset manager class here.

Or if I could get some simpler suggestions on how to store the value
from user into the database, it would be great.

Thanks
AAJ.

[android-developers] full screen issues.

[Onomp]

I'm using a fullscreen theme and when my application starts, my layout
isn't centered correctly unless I move setcontentview farther into the
oncreate, It seems there is some sort of animation being called which
gradually removes the status bar and my layout comes to the front
before the status bar is gone, which leaves the top of my activity
exactly where ever the bottom of the status bar was. There also
appears to be issues with my layout adjusting and losing it's correct
position, when I am working with a virtual keyboard. and another note.
when calling the getview for listview that is embedded within a
dialog, the status bar reappears and disappears 3 times in a row.

Other application I use that are full screen, they work solidly, I
never see the layout getting jerked around or the status bar appearing
and disappearing...

How are they doing it??

[android-developers] Difference between Android Service and Content Provider

[Lily Zhang]

I am developing an app and get confused about the idea of Service and
Content Provider in Android. In practice, what will be the difference
between them?

Content Provider
is a facade and it defines a way to share data among applications. You
many attach a local database to your app or create Content Provider
mapped to a universal database so that all the application on the same
device can share it.

Service
is long running processes that need to be decoupled from main
activity. It has local and remote service. local service is like the
local database, and remote service is like Content Provider sharing
the database info.

What My App is doing?
downloads info. from multiple internet resource in the background (I
suppose this will be Service) and store the info. into database, and
multiple applications will need to retrieve the data, format them and
output them to user (I guess it will be a Content Provider).

What will be the fine line between Service and Content Provider?
Newbie in Android, and any suggestion is welcome.

Lily

[android-developers] Re: connected Motorola Droid not recognized by adb

[authorwjf]

Like you I had similar problems getting my Motroloa DROID to show up
as a device in Android Device Chooser dialog under Eclipse. I am
running the 32-bit version of Windows 7. I found a number of forums
that tried to address this issue, but no one seemed exactly sure what
was happening, and a number of the sites suggested re-installing
Windows.

It just so happens that prior to doing Android development I wrote
device drivers for Windows. So I am at a bit of an advantage here. USB
drivers can be touchy, but you shouldn't have to re-install your OS
and the idea of a "driver boost" app from a third party makes me
shudder. More than likely what is happening is the OS has associated
your DROID with the generic driver that comes with the Windows Android
SDK.

You can verify this by bringing up the Windows Device Manager. If in
your root node you see, ANDROID PHONE instead of ADB INTERFACE, this
post should solve your problem. Obviously, if you have not already
gone out to the Motorola website and downloaded the 32 or 64 bit
drivers for the DROID, this needs to be your first step.

After you run the MSI you downloaded from Motorola, reboot your
machine, bring up your old friend the device manager again, and
reconnect your DROID. As mentioned in other posts on this thread, you
need to have the USB debugging turned on from the DROID's application
menu.

Expand the ANDROID PHONE node, right click, and choose UPDATE DRIVER
SOFTWARE. You will be presented with two options, the one you want is
BROWSE MY COMPUTER FOR DRIVER SOFTWARE. When the next dialog comes up,
select LET ME PICK FROM A LIST OF DEVICE DRIVERS ON MY COMPUTER.

As long as you have the SHOW COMPATIBLE HARDWARE box checked, you
should see a couple options. Ideally, you are looking for MOT
COMPOSITE ADB INTERFACE. However, in some cases only ANDROID COMPOSITE
ADB INTERFACE shows up. This *should* work as well. The one thing you
don't want is the generic ANDROID ADB INTERFACE, which seems to be the
default (thus the problem to begin with).

Click NEXT and the driver will install. Its possible at this point (in
fact likely), Windows will force you to do a reboot. Once that is
complete you should be good to go. Hope this was helpful!

[android-developers] Greedy Pirates - My First Android Game

Last week I put my first Android Game onto the market, 'Greedy

I would love it if you could have a play and give me some feedback.
http://greedypirates.trevorboyle.com/

I had some initial problems with the OpenGL (which were quickly
fixed), but I received a number of bad ratings as a result. Things are
beginning to slowly pick-up now though.

I have a few improvements in mind, most obviously a high-scores table.
I am also considering implementing 'user activated' power-ups, any
suggestions?

[android-developers] Reading Cause Codes after call

[bastlaca]

Hello.

I have a big problem. I have this task: "... recognise dropped calls,
and get information about cause of the drop...". Use these

For example: If in a phone call the called partner presses the red end
call button, the Call Controll sends the following message to me:  "
Cause No.17 "user busy" " (3GPP 24.008)

So, I would like to read cause codes ( exit codes in Symbian) when the
call is ended. I can use Java or C++ (JNI).

Thank.

[android-developers] Android Device hooked up tot Terminal Server and printing

[VEC]

I'm very excited about the Tablet version of the Android coming to
market and need to know  whether its a viable alternative to using the
costly Handhands running Windows Mobile to achieve the same
functionality.

My concept is having a Salesperson visit a customer's site, whip out
the tablet, connect to the office server thru a Terminal Server
session cellularly and issue an invoice thru a portable printer they
carry.

I've acquired an Android Phone (Sony Xperia-10 w/ Android 1.6),
installed the popular Remote RDP 3.01 and am able to get onto the
company server and run our EDP software.  What I can;t figure out is
how to get a printer to install on my phone so that I can print to
it.

Are there any printers that work with the Android as they do with
Windows?  Could someone help me with this please?

[android-developers] How do the font rendering work on android? Working on Indian keyboard app.

[Sridhar]

I am using Sony xperia x10 mini, android device. and i am an android
developer.

I am planning build keyboard/input app for Indian languages for the
android.

By default, android doesn't render Indian text.

I started with little R&D. I replaced DranSansFallback.ttf with a font
having Indian glyphs.

This worked but there is rendering is not perfect.

Indian languages are complex combination of vowels and consonants. And
it fails to render correctly.
For example:

"ಕ ನ್ನ ಡ"  is rendered as "ಕ ನ್ ನ ಡ".
It is readable but it should be "ಕನ್ನಡ"

I am not sure why this is happening.

Thanks for help in advance:)

[android-developers] Supporting multiple screens

[Albert]

Hi,

My application will have two layouts, one for large screens and one
for normal. For testing I'm working with one phone (800x480 240dpi)
and one tablet (1024x600 240dpi) but both are detected as large screen
hdpi and long aspect ratio, so I'm not able to assign different
layouts.

The only approach I think that can work is to create layout-large and
layout-normal, get the resolution and programmatically set the layout
folder. Is that possible?

[android-developers] Filtering the camera preview

I am trying to display a filtered version of the camera preview.
The code runs without errors but the device is showing the preview
instead of the generated bitmap.

This is the code for my (very small) Activity:
http://code.google.com/p/ruellia/source/browse/ruellia/src/br/com/ximp/ruellia/RuelliaActivity.java

I suspect the view layering and the surface holder type, but so far no
luck... anyone?

[android-developers] Creating new calendar event not setting OnActivityResult params

[Kris Flyer]

I am trying to use the built-in Calendar Activity to create a new
event.

The code i use to start a new calendar event activity is below.

 Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
startActivityForResult(intent, PICK_OR_CREATE_EVENT);

 The problem i am having is that the OnActivityResult method called
after saving the event has a resultcode of Activity.CANCELLED even
though the Save button was clicked and a new event was created. Also,
the Intent data param is null, which should have been the Uri to the
newly created event.


Does anyone know why the OnActivityResult behaves this way?


Thanks
Kris

[android-developers] rule based routing on Android

[Tarun]

Hi


Could someone please suggest how can we do rule based routing on
android?

I'm using multiple interfaces on android (so multiiple possible source
ips)  and I want packets with different source ip to have different
defaul gw.

On linux it can be done as follows:

create an entry for new table in rt_tables file
add a route to this table: ip route add default via xx.xx.xx.xx dev
eth0 table new_table
and add rule that directs to this table in certain scenario: ip rule
add from xx.xx.xx.xx table new_table

however android allows me to do the first step and gives no error in
second step. But the route is not added to new_table and instead added
to default table. If default table already contains a default route
(which it mostly does) an attempt is made to add default route to it
which fails with error "File exists".

 I know that ip route add command does read the table name because if
i give a table name that is not in rt_tables file, it gives error. But
if i give a valid table name, route is not added to it.

could u please suggest how i can add route to my new_table so i can
make rules based on it.

Thanks

Tarun

[android-developers] Retransmissions from PBX after disconnecting from emulator (charging) using sipdroid

[Ken Cross]

Hi,

I'm a newbie to Android development but a very experienced developer
in the area of telephony applications.  I am working on a sip client
for Android, currently working with the Nexus One, Android 2.2 and
sipdroid 1.5.  Connectivity is via Wifi to our PBX.  I am using UDP
protocol.

My problem is this.  When the application starts, it of course
registers with the PBX (via wifi).  The REGISTER is responded with a
200 OK from the PBX and the phone is registered.  This works fine when
the phone is connected to the PC and charging.  However, as soon as I
disconnect from the PC (now running on battery), the first 200 OK for
REGISTER appears to be never received by the phone.  This causes a
retransmission of the REGISTER after 2 seconds, to which the PBX again
responds with a 200 OK which is now seen and the phone registers.

I have gone fairly deep into debugging this but as of yet have found
only dead ends.  Any help or advice would be appreciated.

I hope this is the right place to post this.  If there is a better
place, please let me know.

Thanks,

 - Ken

[android-developers] Can't access proximity sensor on Droid X

[Dmitry]

I'm writing an app that uses the proximity sensor, but
registerListener keeps returning false whenever I try to register to

empty list, but the sensor works fine during calls and according to
the log, SensorManager actually finds the sensor:

08-18 18:14:38.284  2077  2077 D SensorManager: found sensor: Ambient
Light sensor, handle=5

I had my phone replaced due to a dead pixel and the app ran fine on
the old one, so am I missing something simple or is this a hardware
issue?

[android-developers] Re: Optimizing image processing algorithms for Android

[Indicator Veritatis]

I leave it as an exercise for the reader to establish whether it is
efficient or convenient to do so, but the graphics.Matrix class
certainly can be used to implement linear filtering operations (e.g,
IIR, FIR). I am also sure that the class would be much more convenient
if it would support arbitrary matrices instead of only 3x3!

That said, clearly the graphics.Matrix class was not designed for
this: it was designed for the linear transformations most commonly
used in 2D graphics, that is, those of homogeneous coordinates for a
two-dimensional space (so that all geometric transformations can be
represented by linear transformations).

I said your apps must not be very complicated - in no way was that meant as
an insult. A simple app is *a good thing*.


> My point is a DESCRIPTION should be short.
>

My points are:
* the Android Market "description" field is much, much more than just a
description
* users and developers should simply have the CHOICE of how much they want
to say / read in these descriptions
* even the clueless individuals running the Market should be able to handle
incrementing this limit which would then *EASILY* solve many of the other
complaints (changelog, technical stuff, quick response to comments, etc)

You like the 325 character limit? Great. If we had more space, you wouldn't
be forced to use it all, nor would you be forced to read all of the text a
developer posted. So keep posting 325 character descriptions and only read
that much. Some of us, though, would love the *option* to say and read a
little more.

Again why I suggested the "read more" idea. A 325 character DESCRIPTION,
nice and short how you like, with the *option* to go into detail.

 This is why there should be a "technical note" field (where you could also

What's the point of adding another, separate field for "technical notes"
instead of just extending the description space and using that and saying:
"Technical Note: Don't be a dumbass" (or whatever).

[android-developers] Re: Paid vs Free, My Early Experience

[String]

Absolutely agree, and that's kind of my point. If the Market was more
full featured, 325 chars for just the "description" would probably be
fine. As it stands, though, it's woefully inadequate.

I can imagine that there might be obstacles to adding tags, or comment
replies, or most of the other features. I CAN'T imagine that
increasing the description size could be very difficult, and that
would be a short-term solution.

Oh, and I forgot one in my earlier list:
- The obligatory "Any bugs? Please EMAIL me!", because users seem to
think that I can debug from a comment like "Force closes on Droid.
1*"  o_O

In that case you could probably manually re-insert the overlay into the
MapView after calling disableMyLocation. This is of course way into hack-job
land, but I think you crossed that border a few posts ago =P

This is a good point but doesn't it mean that rather than asking for a
longer description field, we should ask for other features, such as a
changelog, a way to respond to comments, a technical note field for example?

As I said, I think the market needs improving. I, for one, would like
tagging because categories are too restrictive. There is no point insulting
me by saying my apps must be simple because I can describe them in 3
sentences. My point is a DESCRIPTION should be short. However, we need other
features to be able to convey all the information we want to/have to for
users to be able to fully enjoy the app (technical stuff, changelog etc) and
to be able to interact with users (responding to comments, changelog etc).

For example, one of my apps is a soft keyboard and I have to use one
sentence to explain to people how to select it as their default soft
keyboard (not all users understand how all the settings work). This is why
there should be a "technical note" field (where you could also describe
hardware limitations for example) and I'd rather ask for that than for a
longer description field.

As for other languages, yes, I agree, Google should adapt to local
particularities of languages and if 325 characters is too low a limit in
russian, then they should set another limit for it. It's all part of
localization.

[android-developers] Sending EMAIL

[lloyd1949]

Hi guys:
I have a situation where I allow the user to email a number of
documents from my app. The problem is that one request may result in
the sending of 3 or 4 emails. Ideally I would like to get all the SEND
info at the beginning and at a minimum populate all the fields so that
all the user has to do is hit SEND for the 2nd, 3rd, 4th etc email.

All is fine except that the email client seems to accept the email
address only when typed in manually: Below is a snippet of my email
routine:

private boolean emailInfo(File filename, String subject, String
body) {
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TITLE, "Extra Title");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "subject");
sendIntent.putExtra(Intent.EXTRA_EMAIL, "theem...@comcast.net");
sendIntent.putExtra(Intent.EXTRA_TEXT, "body");
sendIntent.setType("text/csv");
sendIntent.putExtra(Intent.EXTRA_STREAM,
Uri.fromFile(filename));
sendIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
//startActivityForResult(Intent.createChooser(sendIntent, "Select
Mail Client"),101);
startActivityForResult(sendIntent,101);
return true;
}


The email address that I pass via:
sendIntent.putExtra(Intent.EXTRA_EMAIL, "theem...@comcast.net");
is always ignored and so it has to be manually entered on each email.


Any solution? Thanks in advance.

[android-developers] How to manipulate order of views in a viewgroup using drag'n'drop

[Per-Jarle Sæther]

Hi all
I want to develop an application that contains 4 views in one viewgroup

The following interactions shall be possible:

   1. change ordering
  - When you drag a finger from one view to another, the two views shall
  swap
   2. maximize one view
  - When you click on one view, it shall maximize (remove other 3 views)
  - when maximized, a single touch shall give back the quad view
  3. Start rotation between maximized views
  - When push and hold, it shall start rotation between all views
  showing one maximized at a time in the same order as the views are
  organized.
  - When rotation running, a single touch should give back the quad view

I would be thankful if someone can give me some hints how to accomplish
this. If possible with some sample code

Best regards
Per-Jarle
