[android-developers] Problem with GetLongField JNI

2011-10-18 Thread Ajith Kamath

Hi

I m trying to access a private long variable from my cpp(jni) file.
Problem is when I do GetLongField on Field Id , I get zero , even though i
have set the long variable in Java to non-zero value.

In Java long definition is :
private long mActualTrack = 0;

In Cpp file , filed Id is obtained by :
gf_identifier = env->GetFieldID(clazz, "mActualTrack", "J");
clazz represents Java Class which contains mActualTrack
where gf_identifier is declared as static jfieldID gf_identifier;

Now I used GetLongField as follows
jlong id_j = env->GetLongField(myobj, gf_identifier);

I do identifier = (unsigned long long)id_j; , and print its value, But I am
always getting 0.

Can anyone explain this behavior or  am I doing anything wrong in my
implementation??

Regards,
Ajith

[android-developers] Re: Problem with Notification Service and Progress bar

2011-07-20 Thread Ajith Kamath

Hi

You see for my application i need an Indeterminate Progress bar of
Horizontal style.
I think this might be bug with StatusBarService itself. But i'm not sure.
Any suggestions on how to keep animation running?!!

[android-developers] Problem with Notification Service and Progress bar

2011-07-20 Thread Ajith Kamath

Hi

I have written code for Progress bar to appear in Notification bar.
Its runs fine, if i drag down notification slide after Notification was
sent, I can see the Progress bar animation.
Now I drag it back up.
If I drag that down again ,  Animation has paused.

If i turn phone around to landscape now, Animation will start again and work
for only one time(one drag down and up). After that It gets paused again.
I have change perspective(landscape/potrait) to get animation back.

Does anyone know solution to this. I might be missing something: flag or
parameter.
Any help is appreciated.

Ajith

Re: [android-developers] Re: Problem with Progress Dialog

2011-07-17 Thread Ajith Kamath

Hi

Thanks for the all the suggestions.
@kamiseq : I create a new Progress Dialog in my Activity and trying to set
its progress from a thread spawned in this activity.
In the thread I'm doing some work and then setting its progress.

@Mike: Even I'm thinking of the same. Is there any way to confirm that
setProgress doesn't work for Spin wheels.

@rambabu: I've kept setCancellable(true) . Still same problem.

Let me know your inputs.

[android-developers] Problem with Progress Dialog

2011-07-17 Thread Ajith Kamath

Hi

I want to use Progress Dialog in my application with default style(Spin
Wheel).
I use setMax() to set the max value. Now when I do setProgress() in the
Thread, it doesn't work. It doesn't stop when progress reaches MAX value.

So after doing setProgress, I tried getProgress() again to see if progress
was set at all.
I found that Progress of that dialog remained 0 always.

Please suggest. Any help is appreciated.

Ajith

[android-developers] Re: NFC Mifare Ultralight Tag write error

2011-06-21 Thread Ajith Kamath

Hi John

I only had one tag - Mifare Ultralight. I haven't figured out the solution
for this error.
I think it might be the tag error. But I'm not able to prove my contention.
Please let me know if the same thing is happening with multiple tags. Kindly
send your logs too.

Re: [android-developers] Re: NFC Mifare Ultralight Tag write error

2011-05-16 Thread Ajith Kamath

Hi andrew,

As you can see this code checks for Writable and Size limitations.
I tried to write a Contact info. At this time I got Size limitation error.

Anyways i think by tag is writable and also has sufficient size.
Just that I am not able to figure out why that error is occuring..

Also after this error,  I deliberately tried to "Format" and write the ndef
message.
I got "Tag doesn't support NDEF." error.  But this is not possible since
ndef!=null  code was executed previously.

I am not sure why this is happening.
Please advice.

Ajith

I had enabled WriteTagActivity.java and was trying the write application.
Problem is that the code block from where this IOException is occuring tells
me that the tag is already Ndef formatted.

heres the block  which gets excecuted:

Ndef ndef = Ndef.get(tag);
if (ndef != null) {
ndef.connect();
if (!ndef.isWritable()) {
setStatus("Tag is read-only.", false);
return false;
}
if (ndef.getMaxSize() < mSize) {
setStatus("Tag capacity is " + ndef.getMaxSize() + "
bytes, message is " +
mSize + " bytes.", false);
return false;
}
ndef.writeNdefMessage(mMessage);
setStatus("Wrote message to pre-formatted tag.", true);
return true;


Since ndef!=null block is getting executed, i presume its already ndef
formatted.
I don't get "Tag is read-only." or "Tag capacity is " errors..
Exception is happening  when ndef.writeNdefMessage(mMessage) is executed

Let me know if anyone knows why this error is occuring.

Thanks & Regards,
Ajith

[android-developers] Out of Memory Exception when exporting vcards

2011-03-21 Thread Ajith Kamath

Hi

I am facing a problem when I need to export vcards overs bluetooth.
Problem is vcards are large in number. Plus If the vcards have images in
them then size is really high.

So when i try sending this I get OutOfMemory Exception , its Coming from
VcardComposer.java. - At onEntryCreated()

Can I make more memory allocation on the go? Is this possible.
Dalvik basically cannot allocate memory to these data.

Please advice.

Thanks & Regards,
Ajith

[android-developers] Bluetooth UUID receive delayed

2011-03-18 Thread Ajith Kamath

Hi

I am working on Bluez stack and currently facing a problem.
I am able to pair with another phone.

As soon as pairing occurs , it will take about nearly 1 min to get UUID
property changed signal from bluez.
This is happening only with phones

If I try doing it with headsets, I will get UUID signal  immediately after I
receive  property changed signal for "Paired"

Can someone Please tell me what might be causing this error.
any help is highly aprreciated.

Regards,
Ajith

[android-developers] Bluetooth SyncML Server

2011-03-11 Thread Ajith Kamath

Hi all

I am trying to implement Bluetooth SyncML server in Android. But we are
facing few problems.
SDP record registration and connection establishment is successfully done.
Now we get wbml data from Client in form of Obex PUT request.

My problem is I'm not able to cleary define Obex-SynML binding.

1.What should be my response for PUT request of Client. When decoded the
wbxml, it sends Dev Inf and Met Inf data and other Dev CAP(capability) data.
   Should I send Obex -  http ok or Send my Device Capabilities info to
client as response to this PUT request?
2.I had sent my Dev Cap info for that PUT request and got GET request with
empty body.What does this mean??
3.I also changed my response and instead of sending Dev CAP , i just send
Obex - Http ok as response to that PUT request. Again I Got GET request with
empty body. What does this mean??

So I now assume that my Dev CAP info should be sent after we get GET
request. Hence for Client's PUT request I just sent Obex http ok response
and once I get GET request , I send my DevCAP data.
But when I do this I got Disconnect request.

I am not able to understand SyncML- Obex Binding here especially for
different types of sync like Two way Slow sync, One way from client to
server etc.
All I want to do is One way Sync from Client to Server.

The Client that I'm trying to work with is Nokia N8

Any help is highly appreciated.

Thanks & Regards,
Ajith

I went through the changes mentioned about NFC in  2.3.3.
As for the improved Tag read/write support is good, I'm not able to see what
P2P related changes they brought about?!

I cheched the git and was not able to find P2P related commits.
Can some please suggest what P2P related support/changes were made in 2.3.3

Re: [android-developers] Bluetooth socket connection issue

2011-02-08 Thread Ajith Kamath

Hi

Checked the logs. Everything seems to be fine.
I'm not sure what the prob is. Try adding some delay before bluetooth socket
connect takes place.
this might be needed if you are connecting to some headsets/handsfree.

If Still it doesn solve the problem.. Add logs upto jni level and send the
logs.
The logs which you have added so far does not point out any problems .

Also tell what kind of device are you trying to connect to you mobile.?

Hi

>From the attached logs, its unclear what is the error.
Discovery seems to be stopped in an odd manner, but that should not generate
any problem
You need to rig the code , add more logs.

Since the connect thread was called, add more logs in Connect thread
It seems that "*BEGIN mConnectedThread*" is never displayed.
I think there exists problem in connect thread. Please check this.

Also what I meant by my previous question is that, What kind of h/w are you
trying to connect to your mobile(Ex: headset, handsfree, carkit etc etc)

Re: [android-developers] Status of NFC card emulation capabilities in android 2.3.2

2011-02-06 Thread Ajith Kamath

Hi

Card emualtion is not completely supported on Application level yet.
Although stack level support is provided by libnfc-nxp
You can tweak the app and native layer to provide decent enough card
emulation.

Please refer to older posts. There has already been discussion on this and
card emulation related changes were stated.

great mtk, my doubts are getting cleared...
So to work on WI mode , i need to set the SE to wired -interface mode like u
said.

After this if i Use RawTagconenction to send GP commands to SE , Will this
work for WI mode?
I mean can u select the 0 AID with this? . Sorry i dont have device yet, so
still working on with code

If this is the case, then for Credit card emulation , Is my assumptions
correct :
* The cardlet in SE will be given by TSM
* the midlet in mobile application will access SE cardlet via the method you
described earlier(for gingerbread) , but only if its digitally signed by TSM

Are these 2 assuptions correct.? Also can you share doc/link on GP
complaince and commands?
Please advice

Re: [android-developers] Re: NFC Intents: Reacting on specific NDEF types

2011-01-18 Thread Ajith Kamath

I dont think there is such a thing.
You will have to write intermediate receiver for
android.nfc.action.TAG_DISCOVERED

Then separate ndef messages like i said before and generate separate intents
which ever is needed.

Re: [android-developers] NFC Intents: Reacting on specific NDEF types

2011-01-17 Thread Ajith Kamath

Hi Dominik

The 
EXTRA_NDEF_MESSAGES
will
be in that Intent which will contain all ndef messages of detected tag. So
once you get that intent, get all records from that Ndef Message. Check the
type (getTnf ) for
TNF_EXTERNAL_TYPE
and
then check for uri

I hope this answers your question

[android-developers] Re: NFC Secure Element

2011-01-17 Thread Ajith Kamath

I still dont have nexus s but there is a high probability that its Embedded

Yes Keys are private and most likely needs to be provided by Service
Provider. The same thing has been mentioned in nokia forum
But I am not sure  how this will be done for nexus S.(may be there are ties
with Service Provider)

If anyone can explain OTA agent and its communication with TSM, it would be
very helpful. Since this too is not clear (w.r.t android)

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

Hi Nemik

I'm running over the libnfc code.
I can see these 4 files to be prominent for communication with SE

phHciNfc_CE_A.c
phHciNfc_CE_B.c

I am thinking the above two might be used for R/W into SE from App
Processor.
And the below two is used for communication between NFC Controller and SE.

phHciNfc_SWP.c
phHciNfc_WI.c

Please go through these files and let me know if I'm in right path.

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

2011-01-09 Thread Ajith Kamath

Hi Nemik

* I have small doubt with current implementation. Is SmartMX a Secure
Element ?If so can you give me examples?
* I have checked libnfc-nxp , enabling P2P parameter was  at phnfcconfig.h.
what needs to be done to enable Secure element?
what are MifarePlus, Desfire, Topaz . Is it a Card type or Secure Element?


* Also where is the general read-write methods for entry of Secure element.
All I can see is phLibNfc_SE.c is methods for getting list of secured
element, selecting secure element, deselecting.
* But method for exchange of data is not present. Can you tell me where can
I find this?

* In libnfc-nxp There are files like  phFriNfc_NdefMap.c,
phFriNfc_MifareULMap.c,  phFriNfc_TopazMap.c, phFriNfc_TopazDynamicMap.c,
phFriNfc_DesfireMap.c, phFriNfc_FelicaMap.c.
Can you tell me what these files are used for. The current comments in the
file do not provide sufficient information

* I am trying to use Wired Mode, Hence phHciNfc_WI.c will be used to
communicate between Controller and Secure element right?

Please advice.

[android-developers] NFC Card emulation and P2P

2011-01-06 Thread Ajith Kamath

Hi

I saw your discussion on
http://groups.google.com/group/android-developers/browse_thread/thread/165bad53856ea1/fb2620bb1002e5cd?lnk=gst&q=nfc#fb2620bb1002e5cd

My question is we have libnfc-nxp which seems to be entire protocol stack
for nfc.
For Card Emulation i went through the NfcService.java and other nfc package
and framework , it only provides getting, selecting, deselecting
SecureElement.

So my question is that can writing to Secure element be possible with
current code?
If not , Is this support provided in libnfc-nxp?
I personally couldn't find any methods to write into Secure Element in
libnfc-nxp.

Also is P2P read and write provided? For example if i want a contact sharing
service, then LLCP has to be connected to OBEX via protocol Bindings.
Is this support provided in libnfc-nxp? If so has these been made accessible
through nfc app/framework?

Please advice

Ajith

[android-developers] Ginger bread - NFC Card Emulation & p2p

2011-01-05 Thread Ajith Kamath

Hi

I am trying to use NFC on Gingerbread.
I wanted to know if Card Emulation and Peer 2 Peer is possible on present
gingerbread code.

Because looking into api's and framework files I'm clear that Tag reading is
possible.
But Will this code support Card Emualtion & P2P  is doubtful.

*Can some please tell me if these two features can be supported by
gingerbread or not?

Because Card Emulation app will require access to Secure Element(SE) for
example UICC(for LTE devices)
These API's / framework is not provided(atleast I could't find it).

 * Can Someone please tell me if Access to SE is Implementation specific and
code(app and frame) will be provided based on SE separately?

2010-10-12 Thread Ajith Kamath

Hi Dianne

Thanks for info..

I found out the problem was in Avrcp.kl , Its file my system is using for
scancode -keycode generation.
I added following in avrcp.kl after i found that 164,128 and 159  has no
entry at all:

key 164   MEDIA_PLAY_PAUSEWAKE
key 128   MEDIA_STOP  WAKE
key 159   MEDIA_FAST_FORWARD  WAKE

Anyways, Its working now.

Thanks ,
Ajith

[android-developers] KeyCharacterMap problem and Bluetooth Headset

2010-10-11 Thread Ajith Kamath

Hi

I am facing a problem with Bluetooth Headset and KeyCharacter Mapping
When I press play/pause button from Samsung sbh-170 , its not getting
reflected in Phone.
I traced and  came to know that , normally scan code of 164, keycode of 85
is formed when i press Headset play/pause. And PhoneWindow manager will
intercept this and send ACTION_MEDIA_BUTTON if keycode =85
(KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE).

But keycode that I'm getting is 0 even when i press headset play/pause in
PhoneWindow Manager. Even in KeyInputQueue, the keycode that is obtained is
0
Does anybody when keycode gets generated??

Also I got following error in log :

 AVRCP: Send key 164 (1) fd=23
WARN/KeyCharacterMap(2550): Can't open keycharmap file
WARN/KeyCharacterMap(2550): Error loading keycharmap file
'/system/usr/keychars/AVRCP.kcm.bin'. hw.keyboards.131077.devname='AVRCP'
WARN/KeyCharacterMap(2550): Using default keymap:
/system/usr/keychars/qwerty.kcm.bin

Can this be a problem ? If so , how??
Please suggest.

Regards,
Ajith

Re: [android-developers] Bluetooth headset noise-cancellation activation through android app

2010-10-05 Thread Ajith Kamath

Hi Garima

If you are developing application, to control media and phone audio, You
will need to implement it in Framework.
For ex: You can go by sending At commands to Phone - (BluetoothHandsfree)
and immitate as though Headset itself is sending it.
You can refer the HFP spec of Bluetooth for At commands and operation. For
Voice gain and reduction there are specific at commands.
I think you will need to send this to socket of BluetoothAudioGateway.
I'm not sure if this is what you require and if it answers your question.
Let me know.

Regards,
Ajith

[android-developers] Task Manager Killing process. Incomplete kill.

2010-09-24 Thread Ajith Kamath

Hi all

I am facing following issue with respect to FORCE KILL :

Following is done after BT is on:

1. idle - applications - gallery - camera - Select any one image
2. menu - share - bluetooth - 'scan for devices' touch

After this our task manager app is activated by home key longpress.
i kill Gallery and Opp app.
Now when i push back button , Device picker screen is still displaying.

This is because BluetoothSettings was not killed by taskmanager when opp was
killed.

Can you please suggest any solution for this.

Also When you kill the process , even onPause, onStop or onDestroy is NOT
called.
Is there any function which is called when Force kill of Process is done?!!

Please advice.

Thanks & Regards,
Ajith

[android-developers] Bluetooth FTP Server Service implementation

2010-09-07 Thread Ajith Kamath

Hi,

I have written FTP server for Eclair 2.1.
I'm stuck in browsing service. Here I'm able to do forward browsing (i.e
descend into folders).
But when I give up(back), Client(laptop dongle) which I'm using to browse,
is not sending me SET Path request.
But FTP spec v 1.1 says Obex SET PATH request has to be sent when you need
to go back up in folder hierarchy(parent folder).

Because of this anamoly I'm not able to determine if I need to make any
changes in my FTP server code.
Dongle which I'm using as client is  WIDCOMM bluetooth 5.1.0.3300 with
Bluetooth 2.0 fucntionaity.

Please advice

Regards,
Ajith
