[android-developers] Re: How does Chronometer work??

[rachana govilkar]

I did write this code but its of no use as my Chronometer is not
getting displayed only.
And hence this time ticking is not taking place.
Do I need to add some code in code I mentioned above???

[android-developers] how to draw wave like the wave in google voice search

[cindy]

Hi All,

I have got PCM data. I use canvas.drawLines(mPoints, mForePaint) to
draw the wave data. But it doesn't like the wave in google voice
search? In google voice search, the wave has round edge. Which method
I can use to draw wave like that?

Thanks!

Cindy

Sometimes it's advisable to quote the mail you're responding to. I don't 
think anyone knows what you're talking about.


Eclipse. Me too.

Huh?

[android-developers] Re: Android codesearch replacement?

[joebowbeer]

Thanks. The android.jar source code can also be downloaded via SDK
Manager and integrated with an IDE.

I'm looking for a deeper search into android.git.kernel.org (aka
github.com/android). The aapt source, for example.

I thought that is what code search used to provide.

Re: [android-developers] Re: NFC Secure Element

[s.rawat]

Hi  Michael ,
You mean page 12 , section *5.3 Reading Binary Block*.
I tried that, i found as soon as I send the command the green light on the
card reader turns Red for the time being(which I fear is some operation
failed signal) , accompanied by the 63 00 response .I am using the *TestResMan
*tool.Even though it shows Command is sent successfully and response
is received in XXX secs.
Can you tell me the name of card reader where we cant see
this behavior (reader automatically performed protocol selection up to ISO
14443-4 / APDU layer)

[android-developers] Re: DevicePolicyManager LockNow problem

[albnok]

You might have missed something in the implementation - it should
cause the Device Administrators window to pop up, and you need to
Activate your app as a Device Admin.

Then only isAdminActive() will return true.

[android-developers] Forcing an item in a GridView to remain highlighted after clicking

I would like to make the blue border around a gridview item remain
highlighted after clicking on it as a reminder to the user which item
was slected while making the second choice. I have tried a number of
methods from the View class and none of them seem to have any effect -
the border disappears after a short while. Any ideas how to do this?

[android-developers] Re: Copyright question: Can I remix a Final Fantasy song and use it in my game?

[hzakimoto]

Hi,

Thank you all for replying. And sorry for being off-topic. I didn't
know it's off-topic. My apology for my stupidity.

The thought of using FF music never crossed my mind until I heard
Chrono Trigger song from one of the Top Free game.

I can create my own music. No problem with that. But if you're also FF
(Music) fan, I think you understand why I want to include some tracks
in my game. It's a dream.

But judging from the answers, I'd better off creating my own music as
I always do. =)

Thanks again.

[android-developers] Best way to have Service inform Activity where user currently is

[James Black]

My navigation program is all in an Activity, and now I need to have the
part that makes the determination where the user is.

So, the activity will be in charge of drawing on the MapOverlay, but the
Service will be getting the location updates.

How should the service inform the drawing activity of the current location
and the path?

It would seem that the activity should probably just poll the service, so
that if there is no request for information then the service will just
quietly keep track of what is going on, and just put up a notification when
the user reaches their endpoint.

But I am not certain if this is the best approach.

Thank you.

[android-developers] Re: How to Increase frame rate (fps) from onPreviewFrame??

[gjs]

Hi,

You could make minor? improvements by doing the standard optimizations
of moving various static queries and variable initilizations to
outside of the onPreview method.

For example, most of this code does not need to be executed for every
onPreview method call -

Camera.Parameters parameters = camera.getParameters();
int format = parameters.getPreviewFormat();
 //YUV formats require more conversion
if (format == ImageFormat.NV21 /*|| format ==
ImageFormat.YUY2 || format == ImageFormat.NV16*/)
{
int w = parameters.getPreviewSize().width;
int h = parameters.getPreviewSize().height;

...

// Convert YuV to Jpeg
Rect rect = new Rect(0, 0, 320, 240);
ByteArrayOutputStream output_stream = new
ByteArrayOutputStream();

Also you might query camera parameters to see if you can change the
preview frame rate -

http://developer.android.com/reference/android/hardware/Camera.Parameters.html#setPreviewFpsRange(int,
int)

Since I only need the memory threshold functionality
I could easily implement the functionality in Android
by myself by polling Runtime.freeMemory() in a thread.
The later is available in Android.

But it would be more handy if there is some existing

Re: [android-developers] Re: Share file or an variable between 2 apps

Hello Kristopher,

=) you are right about my teacher, he loves Unix and everything with 
*ix. I don't blame him about
giving us such assignment. Althought the assignment was not super, we 
did learn about Android SDK, NDK, JNI. Overall: it has not been a waste.


Thank you for the link about serialization will read and learn. Every 
bits of information help. Some more then others.


Thank you A. Elk for telling about serialization at the first place. I 
really did not have a clue where to look.


Thumbs up!

We have have made a server / client app using sockets in C, because that was

Just to show our teacher "found it!" Althought the assignment was not clear

Would be great if someone could tell about sharing with UID, even thought it

knows, do send an e-mail. So that we might close the "quest" with good
content

Are you sure that this is the assignment?

You can force two applications to have the same UID by using an attribute
of the  element in AndroidManifest.xml. This is documented in
Security and Permissions,
http://developer.android.com/guide/topics/security/security.html. This guide
also describes the ramifications of sharing a UID. Once you do this, the two
application are treated as "one" by Android, so they share the same
"sandbox". This means that a file written by one can be read by another. To
share a variable, you could create an object and then serialize it to a
file.

However, I strongly recommend against doing this sort of thing. It's not
the way Android is designed to work. Applications should avoid knowing too
much about one another. An application A should use common APIs to send
information to an application B, with the assumption that B could be
anything.

In summary, I think it's a bad assignment.

Re: [android-developers] Re: Share file or an variable between 2 apps

[Chihwah]

Hello A. Elk,

Yes, I am doing MPNA "make an high performance networking application"
During the course we learned about C programming, threading, networking, etc
My teacher himself read about Android and it's possibility to share data 
between two apps and gave us the assignment to find out about having the 
same UID and be able to communicate.
After searching for weeks, I know that android security is not fond of 
such practices, Android has a few ways to communicate, for example 
content manager.


We have have made a server / client app using sockets in C, because that 
was the easiest and most straightforward way we knew. But even then I 
like to know how to share data using the same UID.
Just to show our teacher "found it!" Althought the assignment was not 
clear or good enough we tried our best.


Would be great if someone could tell about sharing with UID, even 
thought it will not influence our assigment results any longer. If you 
or someone else knows, do send an e-mail. So that we might close the 
"quest" with good content


Kindest regards,

Cw

You can force two applications to have the same UID by using an 
attribute of the  element in AndroidManifest.xml. This is 
documented in Security and Permissions, 
http://developer.android.com/guide/topics/security/security.html. This 
guide also describes the ramifications of sharing a UID. Once you do 
this, the two application are treated as "one" by Android, so they 
share the same "sandbox". This means that a file written by one can be 
read by another. To share a variable, you could create an object and 
then serialize it to a file.


However, I strongly recommend against doing this sort of thing. It's 
not the way Android is designed to work. Applications should avoid 
knowing too much about one another. An application A should use common 
APIs to send information to an application B, with the assumption that 
B could be anything.


In summary, I think it's a bad assignment.

[android-developers] Re: content provider

[A. Elk]

A sync adapter doesn't automatically communicate data to and from the 
cloud. It's more of a convenience class that scopes out the methods you'll 
need to implement in order to *synchronize* data linked to a particular 
user account, and do it on a regular schedule. In that way, a sync adapter 
ties into the synchronization infrastructure that's part of the OS.

The documentation uses content providers because the primary use case for a 
sync adapter is communicating data from a cloud service to and from a 
central repository of data on the device. The easiest way to manage such a 
repository is a content provider, but it's not mandatory.

>From what you've said, you want to move the files from the device to the 
cloud. Do you want to move files from the cloud to the device, such that 
you can force the cloud and the device to have the same versions? 
Synchronization is not just moving files back and forth; it's *intelligent* 
movement 
that guarantees that two places have the same data. If you need that, then 
you need synchronization. Of course, even if you're *not* synchronizing, 
you need some sort of network transport, but if you're just sending files 
to the cloud then you don't need a sync adapter.

The Android sync adapter framework assumes that sending data to the cloud 
requires authentication and authorization, which is reasonable for 
real-world use cases. The sync adapter is associated with a user account, 
so the user doesn't have to enter credentials every time a sync occurs. The 
rest of the work is having the sync adapter figure out what needs to be 
updated on the device, and then what needs to be updated on the cloud. Even 
if you're using files, it's easier to track the device state within a 
content provider. You can write a content provider that tracks metadata in 
tables but also has URI links to files you have stored on the device.

Re: [android-developers] Android webview retain form data when orientation changes

[Mark Murphy]

Better yet would be to have the WebView in a dynamic fragment with
setRetainInstance(true). Passing a widget between activity instances
requires some patch-up work to avoid memory leaks -- you're better
served letting existing Android code handle that.

As has been stated, you need a lawyer. This is way off-topic for this list.
In general, if you have to ask "is this OK?", it's probably best to assume
it's not.

Re: [android-developers] Re: Copyright question: Can I remix a Final Fantasy song and use it in my game?

[Christopher Van Kirk]

You're assuming that they didn't pay for the right to use that song. If 
you pay the copyright holder, you don't necessarily have to credit them. 
Whether or not you credit is up to the agreement you have with the 
copyright holder.


Anyway, this is a question of law not Android, so it doesn't belong on 
this list. Go talk to a lawyer.

I didn't see the original thread you're responding to, so what's your question?

As in you want your service to stop using resources when the screen is

[android-developers] Re: How does Chronometer work??

[Brian Dols]

before you call chrono.start(), try adding a tick listener:
chrono.setOnChronometerTickListener(new 
OnChronometerTickListener()
{

@Override
public void onChronometerTick(Chronometer 
chronometer) {
long elapsedTime = 
(System.currentTimeMillis() -
chronometer.getBase()) / 1000;
String currentTime = 
Utils.verboseTime(elapsedTime);
chronometer.setText(currentTime);
}
});

[android-developers] Share file or an variable between 2 apps

[chihwah li]

Hello all,

Been searching about the following subject but did not find anything
usefull. Hopefully there is someone who knows the answer to my
question (my school assignment:

"Share a file or variable between 2 apps using the same UID"

I read a lot of controdicting posts on the internet, and that it's not
supposed to be used by "normal" developers. I want to write data on
app 1 and read it from app 2, just by using sharedUserID and direct
access to the variable or file.

I need to have proof for my school assignment that the same UID  in
both Android apps can let them communicate.

Will someone who is not "normal" (aka "Android super expert") and
knows the secrets of UID, please tell me how Been searching for
long...

Big thanks in advance =)

Chihwah Li

PS: my only demo apps is: 2 apps with the same package name then
access the file from 2nd app. But this demo is useless because the 2nd
app is de-installed because it's using the same packet name

[tofeeq ahmad]

I am working on Augmented Reality from last 7 days.I implement AndAR
API library for this purpose.My problem is creating marker.I used some
online marker generator.But all has one limitation that every pattern
should have black border around it otherwise it will not make a

black square paper then marker generator generate pattern and AndAR
detect bulb with background black square,But if i remove background
image then it do not able to detect bulb.


My aim to detect physical bulb.And physical bulb does not have any
black border around it.So how to make pattern for physical object and

[android-developers] Android Custom Streaming Media Player

[Ken]

I have an application that streams videos from my server. The files
end in .mp4 and play fine in the default android player. The thing is
I don't get enough out of the ads displayed on the app as the time of
the user spent on my app is very less compared to the time spent while
watching videos. So, I was thinking of integrating my own custom video
player to the app I made and display banner ads in it while the video
is streaming.

How can this be done?

Thanks

[android-developers] Android webview retain form data when orientation changes

[IndianDragon]

How to retain the form data in the webview after the change the
orientation ? I have used onSaveInstanceState() and I have restored
the previous state using restoreState(savedInstanceState). This
successfully restores the previous state before the change in
orientation but it does not restore the data in the text box of the
form in the webview.

What should be done to retain the data in the text box of the forms in
webview after the change in orientation ?

Note: I would not be using android:configChanges="keyboardHidden|
orientation as I need keyboard input for my application after
orientation changes.

Thanks in advance.

The answer is probably:

This is technically illegal but this game hasn't been pulled from the
market because the market is very big and nobody has reported a
copyright violation yet, if anybody ever does, then this app will
probably be pulled very quickly.  The market tends to take a hard line
on copyright inquires, and doesn't side with the developer too well,
you can read through this list's archives to find the horror
stories...

[android-developers] change fastscroll overlay size

[elliotn]

I have a ListView which has fastscrolling enabled with the index to my data 
being between 1 and 4 characters long. Unfortunately, the 4 character index 
text is wider than the fastscroll overlay. 

I'd like to change the width of the fastscoll overlay. I see 
fastscroll_overlay_size defined in dimens.xml and used by 
FastScroller.java, but I don't see something like 
setFastscrollOverlaySize(). 

I don't suppose there is an easy way to change the overlay size 
programmatically that I'm missing? 

Thanks-

[android-developers] [android developers] bluetooth insecure connection still requests pairing on my ICS

[rapgaroo]

I own a Nexus S and it's currently running ICS 4.0.3 (OTA from T-
Mobile). I have my own application which does Bluetooth connection
stuff using Insecure method to ignore the boring pairing process.
After when I updated my Android OS to ICS 4.0.3, my app is requesting
for a pairing with the Bluetooth device even though I'm using
createInsecureRfcommSocketToServiceRecord method. I already changed
API to 4.0.3 for the application but I cannot find any clear answer to
this type of problem.

I observed LogCat and the BondState goes from 10 to 11 when the device
requests for pairing. If I do the pairing for once, it does not ask
for pairing of course but it is not listed under paired device on the
Android system.

Also, in this case, the BondState goes from 10 to 12 when it
successfully connects to the device.

Anyone has advice or idea to this matter?

Thanks in advance.

Re: [android-developers] Re: content provider

[Kristopher Micinski]

I think you seem to be misunderstanding the use of content providers in Android.

In Android, there is a heavily sandboxed model.  If you write an app,
there are a variety of ways that you can persist information.
SharedPreferences, files on SD, databases, just to name a few.
However, in theory apps should not be allowed to touch other apps'
data (however you will note this is not the case on either a rooted
device or some situations in which you put files on the SD card,
etc..).  A content provider solves the problem of presenting a common
interface to external apps who might want to interface with your app
to exchange data, it's not intended for interfacing with things like
external web services.  This isn't to say it wouldn't be of utility if
you wanted to exchange data with another app on the device that synced
data with the server, or a number of other uses you might envision in
this scenario.

But in brief, if you want to sync with an external service, you don't
want to be using a content provider, you want to be using some library
which will do communication with the server using whatever protocol
you need (restfully, etc...)

But echoing, what do you need from it?  Typically when Android does
not include something, it's because those things don't make sense
w.r.t the Android way of doing things.

Hi, Mark.

there seems to be documentation about using the SyncAdapter for this
type of operation but that the implementation requires
ContentProviders. Ideally, my app would be able to sync with the cloud
on some basis, say hourly, the same way sugarsync does with my phone,

True. I was thinking there was a hook already to generate userdefined
properties, e.g. using a properties file or similar.

I need to pass them from ant to my app somehow. ISeems like file
generation is the best option.

Re: [android-developers] content provider

[Mark Murphy]

A content provider would have nothing much to do with it.

If you wish to upload files, upload them. If you wish to download
files, download them. There is nothing in the Android SDK that is a
"sync this directory of stuff with this online counterpart". I'm not
even aware of a third-party solution for that, though I seem to recall
there was some work going on for a git client library.

Re: [android-developers] threading : two independent events

[vishal garg]

Hi mark,

I feel I explained things loosely. Let me get into the specifics. I
have an application which does two things - collects GPS data and
sends to server in the backend and on frontend shows a
website(contains my customized maps). I am trying to get things work
simultaneously and it works fine on emulator but when I tested it on
the real device - samsung galaxy ace; the thing worked. Now, here is
the problem - if I analyze the data, though the application started
the GPS location finder but never sent anything to server. The website
loads once partially and then afterwards the whole application is
hung.

I tried to incorporate threading and Asynctask class but no solution -
gave Application Not Responding(ANR) error. Would like if anyone could
refer to similar examples or suggest a solution.

Code :
=
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

//downloading the website
setupWebView();
//getting the GPS coordinates and sending to server
getLocation();
}

private void getLocation() {
LocationManager locationManager =
  (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
String provider = locationManager.getBestProvider(criteria,true);
locationManager.requestLocationUpdates(provider, 1, 0, this);
}

 private void setupWebView(){   
  webView = (WebView) findViewById(R.id.webview);
  webView.setWebViewClient(new HelloWebViewClient());
  webView.getSettings().setJavaScriptEnabled(true);
  webView.loadUrl(MAP_URL);
  }
=
Thanks.

You don't, because you aren't in control of the VM.

You don't, because "userdefined sysproperty" has nothing to do with
"dex generation" any more than it does "stock Java VM bytecode
generation". As you note, in standard Java, you are defining system
properties via command-line arguments -- there are no command-line
arguments for SDK apps.

You could generate a resource file containing the properties (e.g., an
XML resource).

Or, generate an asset file containing the properties.

Or, drop the properties entirely.

[android-developers] How can I get a user-defined sysproperty in an Android app?

[petter]

How can I get a user-defined sysproperty in an Android app?

In a plain Java app I can do something like:



  



And in main.java I do:

String gitSha1 = System.getProperty("git.revision");

But how can I do this in an Android App? I can get predefined system
properties like "java.specification.vendor" etc. but I don't know how
to attach my userdefined sysproperty to the dex generation.

I can also get around this by generating a source file containting the
properties, but I was hoping for a more suitable method.

[android-developers] Re: No Video but audio present when using MediaPlayer on the emulator

[rperi...@yahoo.com]

Okay I got it done using the DDMS file manager. I have to say your
original thoughts about reasons for the video not playing is
absolutely correct. With your app I can also hear the audio but cannot
see any video. I can also see the all the control buttons and the
progress bar. I do not get the control buttons on my app but in my app
I'm using the MediaPlayer directly - not through MediaController.

I guess I will need to move to using a real device.

Have you looked at AbsListView.OnScrollListener?

As for breakpoints, perhaps the framework sources you use for debugging are
not quite the same as used by the device.

[android-developers] Is possible use AlarmManager to schedule run a Service

[Tomas Prochazka]

I use this code to to schedule run Service.

AlarmManager alarmManager = (AlarmManager) 
getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(this, MyService.class);
PendingIntent pintent = PendingIntent.getService(this, 0, i, 
PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.ELAPSED_REALTIME, 
SystemClock.elapsedRealtime() + RECHECK_INTERVAL, pintent);

It works. But when I kill the app in task manager. Alarm doesn't run it

Why? Where is problem?
