 Hi everyone,

 sorry if this topic has been discussed before, I didn't find a
 definitive answer.
 I am developing a game with Google Play Game capabilities (leaderboards
 & achievements).
 I implemented Google+ sign-in, following the tutorial and the provided
 code examples.

 Everything is working fine, but the problem I am currently facing
 occurs in the following scenario,
 at least on an Android 2.2 device :

- I have two Google accounts, both of them are declared and syncing
on my device
- I start my game, and a dialog (of my own) asks me whether I want
to use Google Play Game capabilities,
and therefore if I want to sign in to Google+
- I click 'Yes' and my code starts calling the Google+ sign-in API
- Android Google+ API kicks in and asks me to choose one of my two
accounts to sign in

 What I'd like for my future players is allow them to do this once, and
 never bother to sign in again (if they
 allow it, of course). Is there a way to tell the Google+ API to use one
 account in particular and use it to
 sign in automatically ?
 I can understand that a completely silent sign-in can be a privacy
 concern, but is there a way to store
 which account was used and use it later ?

 Thanks

2013-09-20 Thread FReDD 
Well, here's an update : you actually solved my problem. The key part here 
is what you mentioned : *unless they signed out*.
I had implemented an automatic sign out on leaving the game, I mixed up 
Google+ sign in and Games Client connection.

A big thank you,

Re: [android-developers] Re: Should SQLiteDatabases be limited to 2Gig?

2013-09-20 Thread Kostya Vasilyev 
If that's really it, I wonder why you never see ads or reviews saying
"This 32 core, 6GHz device with a 6" 4x HD screen can corrupt your
data up to four times faster than the closest competitor"!

Seriously, why is this not part of the compatibility test (I realize
it maybe a difficult thing to detect, but it's users' data at stake).

Some of us still shiver from all the data storage issues that the
original Galaxy S had.

Curiously, I'm also getting - admittedly rare - reports of shared
prefs values randomly changing, including some in files that the user
can't touch in the app's UI.

On the other hand, if this is flash memory going bad on some specific
devices (as opposed to device models), then how does the user run
chkdsk / fsck / surface scan / whatever to detect it?

I don't know what, though, because the connection code is pretty

[android-developers] Good time to register for AnDevCon today - discount

2013-09-20 Thread Nathan 
AnDevCon is in San Francisco on November 12-15th. 

It's a good time to register today. You get $400 off full price through 
today. 

On top of that, you can use the Discount code 'Mellor' to get $200 off of 
whatever ticket you order. 

I'm speaking in "Apps for Profit" and "App Discovery Optimization". But 
many smarter people than me are also speaking. You know some of them from 
these groups. 

Let me know in this thread if you plan on attending. I will see you there.

I haven't seen that in the TOS 
(http://play.google.com/intl/en_us/about/play-terms.html)...what part 
exactly do you mean?   I searched for "compet" and "replace".

It'd just be an alternative.  People have written back ends in other 
languages before.  Google's value add is their GAE infrastructure for 
scaling.

I doubt such a thing exists, because I doubt Google would be very happy
with you using their protocol for an app.

There are specific clauses in the TOS for Play (at least) that stipulate
you can't write apps that could compete with Google apps, under which I
presume this use would fall.
