[android-developers] Google Checkout Account

[katarina]

Dear friends,

We are developers from Serbia and Canada. We want to sell our
application on the Google Market. We want to connect our Google
Checkout accont with a bank account in Canada.

But when we try to open up a Google Checkout account from Canada it
will not let us do, because only options for addresses are US and UK.
As well as the tax information.

What are we doing wrong? What do we have to open first, is there some
developer account that we can open and then connect it to the Google
Checkout with information from Canada?

Something is wrong here and we don't know what.

Many thanks to everybody on the forum,
Katarina

[android-developers] Re: Google Checkout Account

[katarina]

To even describe better, when we go directly to Google Checkout, but
not through "Google Play Developers Console",
then, it only gives US and UK addresses options.
Will it be different through "Google Play Developers Console", will it
let us insert address and account from Canada?

All the best,
Katarina

Re: [android-developers] WifiDirect with WifiDirect NSD

[Zach]

Hi,
Thanks for you response.
yes I am making a call to requestConnectioInfo inside 
the WIFI_P2P_CONNECTION_CHANGED_ACTION notification.here is the code 
snippet for that

NetworkInfo networkInfo = (NetworkInfo) intent
> .getParcelableExtra(WifiP2pManager.
> EXTRA_NETWORK_INFO);
> if (networkInfo.isConnected()) 
> {
> // we are connected with the other device, request 
> connection
> // info to find group owner IP
> mManager.requestConnectionInfo(mChannel, mService);
> //mService.requestGroupInfo(mService);
> }


but the fact is I am not getting any WIFI_P2P_CONNECTION_CHANGED_ACTION 
notification. On connect call back I am getting a success what does that 
means.  dont think that means a connection is established .But everything 
works fine if i dont run Network service discovery on wifidirect.

I have noted one more interesting fact that I I do a debug with putting 
break points in all wifidirect call backs mainly a breakpoint inside 
onPeersAvailable() it works fine. No idea what that implies?

Thanks

[android-developers] ffmpeg not working on device

[Narendra Singh Rathore]

Hello all,

I am actually running the following command using ffmpeg on terminal for
making a video from a no. of images.


ffmpeg -f image2 -r 08 -i %05d.jpg -vcodec mpeg4 test12.mp4


This is working fine, if I save the images inside ffmpeg and try to make a
video at the same location, using terminal. But in case I use this command
in my application, and try to execute that on device, that isn't working at
all.

By the way, I have stored images inside sdcard and trying to make video on
the same location (i.e, sdcard).
In my application, I used the command as follows:


void convertImg_to_vid()
{

try {

 String ffmpeg_cmd= "ffmpeg -f image2 -r 08 -i /sdcard/%05d.jpg -vcodec
mpeg4 /sdcard/test4.mp4";

 Runtime.getRuntime().exec(ffmpeg_cmd);


} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}


One more thing, for ffmpeg assistance, I have included ffmpeg library in my
project.

Please, direct me, where I am wrong.


Thanks and Regards
NSR.

[android-developers] Audio Over Bluetooth Mono Headset working in Gingerbread and not ICS

[Ahmed Abdelfattah]

I have written a simple app that records and plays audio through a 
Bluetooth Mono headset usingstartBluetoothSco(). The app works fine on 
Gingerbread but fails to work on ICS. The output of logcat is strange

D/BluetoothSocket.cpp( 1554): ...connect(76, SCO) = 0 (errno 115)
D/BluetoothSocket( 1554): called connectNative
D/Bluetooth HS/HF( 1554): mOutgoingSco.connect() success!
D/Bluetooth HS/HF( 1554): connectSco()
D/Bluetooth HS/HF( 1554): Routing audio for outgoing SCO conection
D/BluetoothHeadset( 1554): setAudioState
D/BluetoothHeadset( 1554): setAudioState
D/Bluetooth HSHFP( 1554): AudioStateIntent: 00:23:7F:EB:4F:10 State: 12 
PrevState: 11 
D/BluetoothSocket.cpp( 1554): readNative
D/BluetoothSocket.cpp( 1554): readNative
D/BluetoothSocket.cpp( 1554): readNative
D/BluetoothSocket.cpp( 1554): readNative
D/BluetoothSocket.cpp( 1554): readNative
D/BluetoothSocket.cpp( 1554): readNative
D/BluetoothSocket.cpp( 1554): readNative
D/BluetoothSocket.cpp( 1554): readNative
D/BluetoothSocket.cpp( 1554): readNative

It keeps calling the Native read from socket function till the app (sco 
connection) is terminated . It's worth mentioning that  tried tha app on 
Samsung Galaxy Mini(Gingerbread) , HTC (Gingerbread) , pandaboard(ICS) and 
ODROID-X(ICS). 

Any suggestions for why the app stucks and readNative is being repeatably 
called ?

[android-developers] What is the norm these days to save the state of a custom view

[Satya Komatineni]

The literature seem to indicate a number of alterantives

1. Just have the activity or fragment call a dedicated save and
restore methods especially if the base class of your SpecialView is
View.
2. Use the View's capabilities of onSaveInstanceState() and ignore the
"null" from the VIew implementation
3. Or use the BaseSaveState pattern that is used by things like TextView etc.

Appreciate your thoughts and comments.

Thanks
Satya

[android-developers] Re: WifiDirect with WifiDirect NSD

[Zach]

Hi,
I made it work! Just swapped steps 2 and 3 on server
So on server new order is

   1. Initialize and Start WiFi Direct
   2. Register a Local Service and Start Service Discovery
   3. Start a Wifi Direct Group

With old oder one thing I found was that the client was not getting any 
notification regarding a successful connection once a connection is 
established. But at the same time server receives notification that network 
is formed. So I assume that once connection was made by server the server 
may be passing some acknowledgement back to the client. With previous oder 
server was blocked some how. I am not 100% sure about my inference. If you 
think differently let me know.

Thanks

[android-developers] Dialog options from a library project?

[ColorTheorist]

I've noticed that when developing an SDK library project, there is a desire 
to have a check as to whether the bluetooth functionality is turned on for 
the device before proceeding.
However, as a library project, I am restricted to the absence of my own 
activity.  I had hoped to call the following with the context of the 
application passed into the library:
  new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
This was with the hope that it would wait for a reply before finishing. 
 Since the library is an SDK meant to communicate with a device, it isn't

I suppose I could let the application itself that uses the SDK be 
responsible for doing the check and turning on/off the blue tooth when 
needed, but I figured it would be nice if the SDK itself could do the check 
for them.  I had been hoping that there would be a nice solution for it.

[android-developers] Making the same API key work for both developing AND publishing

[Jason Hsu]

I recently published an app that uses Google Maps.  As you know, you need 
to provide your API key for Google Maps.

When I published the first version of my app, the map display in my Google 
Play app didn't work even though it did work when I ran my app from source 
code.  So I had to change the API key in the source code and republish my 
app, and Google Maps did work in my second version.  However, Google Maps 
didn't work when I ran my app from source code.

Given this conundrum, is there a way I can use the same API key for both 
developing AND publishing apps?

[android-developers] Does content provider run in its own process space?

[Subodh Nijsure]

Hello,

I will briefly describe application I am writing.

1. Application is used in environment where phone/tablet may not have
network connectivity, person is collecting some data using the app on
the device.
2. This collected data is stored using a content provider, that uses
sqlite database (SQLiteCursorLoader from CommonsWare book) and this
content provider is part of library.
3. There is background service that is gets started when upon boot
completed notification, and it waits for network connectivity
broadcast. Once the device has
network connection, it retrieves the data using the content
provider in step 2. This service  uploads the collected data to amazon
cloud service.
We don't want this upload process to happen in context of UI hence
the service.

I read the commons ware book (page 459 to be specific)  and the
database instance that content provider uses singleton database object
based off of getActivity().getApplicationContext().

Now the question is -- what happens if the service (3) is using the
content provider and user starts the UI (1)  that also attempts to use
the same content provider, is the UI going to experience issue opening
the database, is it going to encounter ANR?

Put other way,  does the content provider run in its own process? And
are requests & responses to content provider serialized?

If there is good description of multiple clients using a content
provider (simultaneously) and issues involved would appreciate pointer
to that.

[android-developers] Re: PC Remote Control

[bob]

Why do you want to do this when there are apps that already do it?

I think I tried this one a few months back:

https://play.google.com/store/apps/details?id=com.Relmtech.Remote

It uses Wifi or Bluetooth.

Please use a single process, and simply have the upload work be done
in a background thread.

Page 459 does not say this.

It says that you need to use a single SQLiteDatabase object if you
want SQLiteDatabase to help with thread safety. Page 459 does not
address ContentProvider at all.

Possibly. SQLite implements process-level locking -- you use it all
the time from, say, Ruby. I have not played with its effects on
Android, as I don't waste the user's RAM and CPU with extra processes.

It runs in the process that the rest of your components run in, normally.

I do not think so, but I have been confused on this particular point before.

You were probably first using your debug key then your release key.

No. The key is derived from the signing key for the app, which is the
default debug key in debug / dev mode and your signing key when you publish.

What I do is determine the map key at run time based on the build type and
initialize the MapView with that.

Something like this:

String mapKey = isDebug() ? DEBUG_KEY : RELEASE_KEY;
MapView view = new MapView(mapKey);

I guess then I am confused on if  "sync" thread terminates if the UI
activity is destroyed or not.
What I want to happen is this background thread that syncs data to aws
should never terminate,and ideally it should get started when device
boot finishes i.e. data collected while there was no network
connectivity, should get uploaded to AWS without user having to do it
explicitly.
I do start my service such that it returns START_STICKY in its
onStartCommand(), is that sufficient for the service to keep running
even if activity is destroyed?

Yes it does not mention CP, didn't mean to imply it did.

Have you tried returning START_STICKY in onStartCommand() of the
service. It is supposed to keep the service running till user
explicitly stops the service.

[android-developers] Re: How to detect tablet devices

[Aaron]

I know this is an old thread but in case someone stumbles across this in 
the future the best way (for me at least) to solve this was to get the 
metrics of the screen size (width and height in pixels) calculate the 
hypotenuse then divide by the dpi.  In theory this gives you the dimension 
in inches of the screen size.

With that you can make the decision about what tablet means to you and then 
you can make decisions appropriately, here is a code snippet:


DisplayMetrics metrics = new DisplayMetrics();

getWindowManager().getDefaultDisplay().getMetrics(metrics);

double inches = Math.sqrt((metrics.widthPixels * metrics.widthPixels) 
+ (metrics.heightPixels * metrics.heightPixels)) / metrics.densityDpi;

if (inches > TABLET_SIZE)

{

this.setRequestedOrientation(ActivityInfo.
SCREEN_ORIENTATION_LANDSCAPE);

}
And here are some of stats you get:
Samsung Nexus: 10-23 20:54:16.598: D/Enter(14861): Width: 1196 Height: 720 
DPI: 320 Density: 2.0
Droid: 10-24 07:12:42.436: D/Enter(1823):  Width: 854  Height: 480 DPI: 240 
Density: 1.5
Nexus 7: 10-23 20:55:06.405: D/Enter(15663): Width: 1280 Height: 736 DPI: 
213 Density: 1.33125
Samsung 10.1 10-23 21:10:49.180: D/Enter(3263):  Width: 1280 Height: 752 
DPI: 160 Density: 1.0


These equate to the following:
Galaxy Nexus = 4.3
Droid = 4.08
Nexus 7 = 6.9
Samsug 10.1 = 9.2

Based on this information I decided if a device was over 6 inches I would 
lock the rotation to landscape forcing a specific layout (of course you 
still have to make sure you are picking up the correct layout resources).

It is an imperfect solution but there is such a variance between devices 
and manufacturers there really isn't a perfect solution.

Please allow the user to make that choice. The user may prefer "having
to do it explicitly" versus you trying to keep code running
constantly.

In principle, yes, though I find this to be bad form. A
continuously-running service is rarely the right solution from the
user's standpoint.

I finally got the code to work when using the 
URI: content://com.google.android.music.MusicContent/playlists
I also saw in searching around the web their were other options for this

Is their any documentation on this URI and all the options?

Override this function:

[android-developers] Error while Connecting to MS Access Database From Android

[Aadi Rockzz]

I'm trying to retrieve data's from MS Access Database on my desktop. I didn't 
add any external jar file to retrieve data actually i don't know whether i have 
to export any external jar file for accomplishing this. Here is the code which 
i'm using to connect to Ms Access Database on my PC.

String driver = "sun.jdbc.odbc.JdbcOdbcDriver";
Class.forName(driver).newInstance();
String path="D:/MS ACCESS DATABASE/mydatabase.mdb";
conn = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft 
Access Driver  (*.mdb)};DBQ="+path+";","","root" );
Log.w("Connection", "open");
Statement stmt = conn.createStatement();
ResultSet reset = stmt.executeQuery("select * from tblEmp");

while executing this i'm getting following error on my log-cat

10-25 11:31:40.545: W/Error connection(422): sun.jdbc.odbc.JdbcOdbcDriver

Please Help me to Solve this issue??
