Re: [android-developers] Sprint 4G(WIMAX) tcp connection problem

2013-04-18 Thread Long Pu 
It's galaxy S2.

I believe the GCM works on this phone. I am wondering what GCM does to keep
his socket alive.
It would not seed keep alive packets in short period like several seconds,
this would burn
out battery very quickly.

My guess is that the carrier can recognize the GCM tcp connection and only
keep it alive.

Cheers.
Long

if (sensors.size() > 0) {

Re: [android-developers] Re: Compatibility mode issues on 4.x

The point is - if somebody sees my app on a tablet, like now, they will 
think what the ...? They'll think I have no idea. But if people sees it in 
compatibility mode (or even better, they can't download it), they say, 
okay, the app was not intended for tablets! - That's a huge difference.

Well, my layout is density independent. I misused the density folders as 
approximation for screen size, and it worked well on smartphones

The issue is that this app was never intended for tablets - but, great, in 
Android it's possible to exclude small screens, but not large ones.

Nobody in the company was interested in using this app on large screens, so 
I never got the order or time to do this work.

Now this app is available but the development is suspended - I'm also not 
working there anymore. The app looks perfect in all smartphones. But on 
tabled-sized screens it has mayor errors, because of some calculations I 
had to do programmatically, which seem to have a problem when the screen is 
large, and some places where I forgot nine patch buttons and things like 
that. There where also a lot of backgrounds with bitmap-shadow, where the 
content had to be adjusted very accuratedly to look correct.

So, yeah, if I could, I would just put this application off for tablets, 
because that's was what I was told to, actually. But it's not possible. But 
I thought "Okay, I can resort to

[android-developers] MediaController - seek bar

2013-04-18 Thread Larry Meadors 
I have a audiobook player that saves it's position using a web service.

It has a periodic timer that saves every 30 seconds which works great, but
I'd like to also save immediately after the user moves the position using
the seek bar.

I'm using the built-in MediaController, but it doesn't seem to provide
anything except for the MediaPlayerControl interface.

That interface has a seekTo() method that tells the current position, but
it tells it as you're dragging, so it fires off a few dozen evens as you
drag it. I really don't care about any of those, just the last one.

Any smart people with a tip for me here? I have a couple of ideas, I'm just
not crazy about any of them...

Larry

[android-developers] "textMultiLine and textImeMultiLine"

2013-04-18 Thread John Goche 
Hello,

I am trying to understand the difference between the textMultiLine and
textImeMultiLine options for android:inputType in an EditText. However
I have not been able to understand an answer. The documentation
says IME is a control enabling users to enter text but I don't
understand how texMultiLine is different from textImeMultiLine.

Thanks for your help,

John Goche

[android-developers] Re: Which is more suitable for uploading large files? a service on separate process or ...

2013-04-18 Thread Doug 
I would definitely dedicate a service for things that do persistent work in 
the background.  There is no real advantage to using a separate process 
unless your upload needs a truckload of memory.

Re: [android-developers] Re: Compatibility mode issues on 4.x

2013-04-18 Thread bob 
 

I think the best solution is for you to not use compatibility mode.


I think it was mainly a stopgap solution for when tablets first came out.  
People probably wouldn't buy a tablet if nothing would run on it.  


But tablets have been out long enough so that it doesn't make sense to only 
design an app for a 2 inch wide phone and then run it in compatibility mode 
on a tablet.


Thanks.

Re: [android-developers] Re: Compatibility mode issues on 4.x

2013-04-18 Thread Piren 
Ahh... he might have did it wrong, but that's an over simplification... I 
wish you could use the same layouts for those devices... fact is you cant.
DP and SP do an OK Job to fit each density, but not perfect. The same 
layout on the Galaxy Nexus and on the Nexus S look different enough to 
require modifications if you're pedantic enough or trying to fit a lot of 
views in.
It gets even worse when screen sizes change... thats why they added more 
modifiers (like screen sizes) to allow more control.

Heck, sometimes you'd want to use different layouts for the same screen 
sizes exactly because of the fact the sizes are the same - text that looks 
normal on xxhdpi looks huge on hdpi and text that looks normal on hdpi is 
tiny on xxhdpi.

btw - not to confuse anyone, but it's kinda misleading to say there's no 
correlation between screen density and screen size... Google tried to make 
it so you could program regardless of their values (they didnt succeed) but 
they are correlated (density is defined by screen size after all :-P).

[android-developers] Google+ How to know if application is installed by friends

2013-04-18 Thread rudas 
Hi,

I'm trying to retrieve the people in a user's circles that have installed 
the current application.

I have used the sample application "PlusSampleActivity" provided in the SDK 
and successfully managed to get the list of all people in the user's 
circles.
However, I'm not sure how to get if the person have installed the 
application or not. The documentation available seems to be very limited...

What I have found is 
https://developer.android.com/reference/com/google/android/gms/plus/model/people/Person.html
I'm using below function but this is always returning false. (I have 
created a user that have installed the app and I can see this when visiting 
this user's profile on the web using Google+)

Is there some other API that should be used? Or any other limitations that 
I don't know about (time until it is visible?)?

public abstract boolean isHasApp ()

>  If "true", indicates that the person has installed the app that is

Then you did it wrong. Layouts should be density-independent. The
layout of an Xperia Z (xxhdpi) should be the same as a Galaxy Nexus
(xhdpi), which should be the same as a Nexus S (hdpi), etc., as they
are all the same basic screen size, within fractions of an inch.

Screen size != screen density. In fact, there is no correlation between the two.

[android-developers] Android - how to handle saving file on low device memory(Internal/External memory)

2013-04-18 Thread sumit gulati 
How we can handle the file saving on low device memory(internal/Excternal 
memrory). I know if sufficient space is not available the OS will throw 
IOException but is there any way to handle this gracefully. Also if the 
file size is not known before saving file then how can we handle low memory 
scenario? 

Is there any need to handle the same by checking filespace before saving 
file or catch IOException. What is best practice for some data centric 
applications?

Re: [android-developers] Sprint 4G(WIMAX) tcp connection problem

2013-04-18 Thread Long Pu 
We only see this issue on Boost phones on WIMAX actually. Pure Sprint
phones work fine.

The minimal required period is a crazy value like 3~5 seconds.   Hope this
info can help.
Our guess is that maybe Boost rents other company's WIMAX network, so they
would like to try their best to clean up idle connections.


Thanks.

Cheers.
Long

 Hi Developers,
 I have an background service which connects my server with a TCP
 connection.
 My background service sends a ping packet to my server every
 4minutes to keep the socket alive.
The problem is that the device can not get the packet from the
 server after a short time(3 seconds from my test) after the ping is sent.
This app works fine on other networks(AT&T, verizon).

The strange thing is that if I force the device to connect to
 3G(EVDO revision A), it works fine.

It seems to me that, on Sprint 4G network, when an app sends a
 packet through a tcp socket, and then the socket is idle for
 several seconds, then the app will never be able to receive packets
 from this socket.

I don't think it's related to the 4G signal, since this issue can be
 reproduced every time.

Any suggestions?

Re: [android-developers] Re: Handler Post sequence

2013-04-18 Thread Filipe Madureira 
"If you mean 'android.os.Handler' there is no such method 'Post()'. Did you
mean 'post()' or a different type?"
-I mean post().

I did not copy the code, I typed it to try to explain my problem, sory for
any errors on that.

I will try to ask the question in a different way:

I have a worker thread that needs to post several peaces of code to the UI
thread.
So I am using android.os.Handler post() method.

*How can I ensure that code I "post" to the UI is executed in the same
sequence I "post" it*?

Notes:
-That code needs to run in the UI thread.
-Can't use postAtFrontOfQueue() because the worker thread is posting some
code has work is getting done, so I can't reverse the call sequence to use
this function. Ideal would be something like "postAtEndOfQueue".

Thanks

Re: [android-developers] Re: Compatibility mode issues on 4.x

2013-04-18 Thread user123 
Thanks, Mark. I should have done a better research.

So this leads to a quite stupid situation. I did the work to optimize 
layout for xhdpi devices, like the Galaxy Nexus, and it looks quite well. 
If I set the compatibility mode to 320dp, this willl be lost on all these 
devices. Samsung Galaxy s3/4, HTC One, etc, have screen sizes which will 
make my app go in compatibility mode!

For me this is a bug, specially because the larger the screen, the more 
sense it makes to have the option available to use compatibility mode. And 
precisely then it's not possible.

[android-developers] Which is more suitable for uploading large files? a service on separate process or ...

2013-04-18 Thread AndroidCompile 
Hi,
When an application needs to upload many large files, which would be a 
better solution:
1) Doing this on a separate process (i.e. remote service)?
2) Using a separate thread (or AsyncTask)?

Is there a clear and definite answer to this?

The application, by the way, is uploading things all the time - usually 
very small chunks of data. 
Every now and then it needs to send large files, so I want to do that with 
a separate mechanism then the one I am using.
(BTW for the small chunks I am using a single task thread which works great)
