[android-developers] Games and their data

[Pranav]

Hi,

I am starting on my first game on Android and would like to know about 
where do games like Angry Birds, Temple Run, etc... store their data. For 
high scores and similar data I guess SQLite is OK  but what if I want to 
store and fetch data constantly during game-play? SQLite and File IO are 
out of picture because of their overhead. So where and how do games on 
Android store their data, and yet make sure that the game-play is smooth.

[android-developers] Check the Status of VPN

[Priyanka]

Hello All,

Is there a  system wide capability to check the status of VPN on Android 
device ?

Currently in my app the status of VPN connectivity is checked by hitting 
the url & getting response from the server if the site is available. 
However,
it could be the case that the site is temporarily down but there is 
availability of VPN. So how do I get this status in application.

Regards,
Priyanka

[android-developers] Android memory usage API (USS/PSS) Vs smem report

[Anthony Prieur]

Reading how to mesure accurately a process memory usage 
(http://elinux.org/Android_Memory_Usage), I've been using USS provided 
by PrivateDirty: 
http://developer.android.com/reference/android/os/Debug.MemoryInfo.html

Per D. Hackborn comment 
(http://stackoverflow.com/questions/2298208/how-to-discover-memory-usage-of-my-application-in-android/2299813#2299813),
 
USS reported by the Android API is PrivateDirty.

However when using smem (http://www.selenic.com/smem/), I noticed that USS 
reported by smem is actually PrivateDirty + PrivateClean, so I was 
wondering why this difference and what's more accurate ?

So basically, your goal is to royally piss off your incredibly short-term
users?  What *SANE* reason do you think you have for doing this?  Please
let us know what the name of the app will be so we can all avoid it like
the plague (even if you can't get this to work, it's likely the rest
of the app will suck, anyways.  The second I saw something like that, I'd
uninstall it

Later,

[android-developers] Re: How to start again if some third party task killer has killed my app ?

[Indicator Veritatis]

The link you give is all very good background on tasks and the activity 
stack (a.k.a. 'back stack), but how does that help the OP understand what 
is different in third-party task killers and why it has such a different 
effect on his program? If the third party task killer does it by killing 
the hosting Linux process (as it is rumored they do), then he cannot even 
count on onStop() or onDestroy() being called. Unless he can count on the 
user running Honeycomb or later, in which case he can count on onStop().

Or are you guessing that the "force close" is due to a null pointer? That 
is a very common cause, but not the only one. But in any case, the OP 
should look in the logs to see what exception immediately preceded the 
force close. Perhaps after reading the link you gave;)

Only if you make your own version of Android that makes that possible.
Please visit http://source.android.com to learn more about how to
customize your own version of Android for deployment to your own
devices.

Adobe Flash is no longer available for Android.

This is off-topic for this list, which is for developing apps with the
Android SDK. Please visit http://source.android.com for driver-level
questions.

This is off-topic for this list, which is for developing apps with the
Android SDK. Please visit http://source.android.com for hardware-level
questions.

> Is there any way to plug a AV output to a android device?

Some devices have HDMI out. Some do not. What HDMI-out gets you will
vary by device, especially before Android 3.0. Android 4.2 seems to be
standardizing this behavior some, but I have not yet had a chance play
around with that particular portion of the SDK.

[android-developers] TV broadcast signal on android app

[Paulo Coutinho]

Hello, I'm new on android and I'm checking if I can do what I want on 
android. I'm looking for any way to get the TV broadcast signal into my 
app. I saw that android has a Camera api to access device cams and I'd like 
to know if it's possible to "open" a external USB TV Tuner or Video Capture 
Device by using the Camera API. I'm asking that because I'm also evaluating 
the Adobe Flash as another option to do what I want and in Flash you can 
access video capturing devices with its Camera API (of course you have to 
install its drivers on windows).

Are there "drivers" of such devices for android?
Is there any way to show video from any capturing device?
Is there any way to plug a AV output to a android device?
Is there any other way to do what I want?

Thanks a lot

[android-developers] New OpenGL ES 2.0 Game Engine Option

[Robert Green]

Hi All,

I'm a long time contributor of this group (over 400 posts I think), 
developer of Deadly Chambers, Antigen and several other Android games and 
just wanted to, in good will, let you know about the game engine that we've 
been developing for the past 2 years.  It's called BatteryTech Engine and 
is available at http://www.batterytechsdk.com .  It's full OpenGL ES 2.0 
and was designed around Android so that it would work really well across 
over 1000 devices, maybe more.  It's free to develop but does require a 
license to deploy.  The license gets you full engine source code which is 
something you don't see often from comparable engines.  We completely 
integrated Box2D and everything is bound to Lua to make it really easy to 
script out game logic.  You can also deploy on other platforms, but it 
works great specifically for Android too.

Please let me know what you think, either here, privately or otherwise. 
 Would love feedback and am always happy to support.

Thanks everyone!!

Where did you find the license you were reading?

What do projects that use that license do?

Ah. So those of us lacking host GPU capability
(http://code.google.com/p/android/issues/detail?id=34233) are out of
luck for the time being, I guess. Needing host GPU support for
high-resolution emulator images makes sense, though.

Thanks for the update!

The last time I tried, I ran into much the same trouble. I just tried

I've tried to create an emulator device definition for the Nexus 10 which 
double 1280x800 or 2560x1600.  It won't run and logcat seems to show it in

just 1280x800 as maximum screen size?

What I wrote was:

"The only reason a service would be destroyed within that short a
period of time is if somebody stops it. For example, an IntentService

queued up)."

I am uncertain how much more plain I can make what I wrote above. I am
up for suggestions.

So long as that service shuts itself down once it has the location
data, that's perfectly reasonable, and that's what LocationPoller
does.

I presume that you mean via a PendingIntent. I have not experimented
with that portion of the location API. I would presume that it is
designed for this sort of scenario, but I do not know all of the
relevant characteristics (e.g., do we need a WakeLock?). This is on my
short list to work on in early 2013.

Well, as with your existing listener-based logic, you could remove
updates once you got your desired fix.

Part of what I need to figure out is how well stuff like minTime work
with the PendingIntent stuff, to see how much power is consumed while
our location request is registered. For example, it is possible that,
in your scenario, you could specify a minTime of 1 hour, and Android
would be smart enough to let the device (and GPS, if applicable) fall
asleep between checks. Since minTime used to be a hint, and not a hard
requirement, I never trusted it, but the docs suggest that minTime is
more "real" now... :-)

Sorry, I misunderstood.  Initially you said that the service should not
be destroyed so quickly. I didn't realize that you were distinguishing
between an Intent Service and a regular service.

Is it acceptable practice to have my AppWidgetProvider start a regular
service to handle this kind of work?  If that's the case there's not
much that would likely need to change in my overall code.

What about leaving everything as is but track location updates via an
Intent instead of a listener?  I imagine that would be abusive since an
AppWidgetProvider shouldn't be handling a potentially continuous stream
of intents such as could be fired from the location updates.

Which means your service will be destroyed a handful of microseconds
after that final else. Using an IntentService for location tracking is
a no-no.

Stop using an IntentService. Use a regular Service, one for which you
control the lifecycle.

H.  The service's onHandleIntent is basically a set of 'if/else'
clauses for the intents I am looking for with a final 'else' for any
unrecognized intent.  After that final 'else' there is no other code.

In my logcat I see that the code for determining the location has been
triggered (I have debug statements showing me the available and best
providers) but then I immediately see the service's onDestroy method
logging that it was called.  My test phone is a vanilla HTC EVO 4G
running CM7 with nothing extra installed on it.

Is there anything else that can cause the service to be destroyed?  In
case it matters, the service is being started from the onReceive method
of an AppWidgetProvider.  Is it possible that the service's life cycle
is shortened in that instance?  Either way, how do I make sure I stay
alive long enough for my Listener to get an update?

The only reason a service would be destroyed within that short a
period of time is if somebody stops it. For example, an IntentService
calls stopSelf() when onHandleIntent() ends (if there is no more work
queued up).

Handling periodic locations, triggered by alarms, is tricky, not only
in the location handling but in making sure the WakeLock and
everything is behaving as expected. I tossed together a simple
LocationPoller to demonstrate the sort of stuff that's required:

[android-developers] Location Listener Question

[Jake Colman]

Yes, I know that there are a million resources out there that deal with
the best way to obtain a location and I did google quite a bit before
making this post.  If someone can point me to something I missed, I'd
appreciate it.

Having said this my needs (for the purpose of this question) are quite
simple: Once an hour I want to obtain my location from the Network.

Here is what I did:

1) Created an alarm to trigger once an hour.
2) Invoke LocationManager.removeUpdates().
3) Request location updates, specifying a listener.  I am specifying
   minTime and minDistance values of 0.
4) As soon as the listener is fired, save the location and invoke
   LocationManager.removeUpdates().

I see a few issues with this:

1) I am shutting down the listener as soon as I get an update.  But I
   should probably wait for a few updates in order to allow it to zero
   in on the location (I already have code that figures out best
   location from those available).

2) The listener does not seem to fire consistently.  My location is not
   always getting updated and it looks like the listener is simply not
   getting called.

I ran some tests where I never remove updates.  With the above settings
my listener is being called appx every 45 seconds.  So I know that my
overall code is written correctly.

What is the canonical "best" way to do what I want?  Should I collect
updates in my Listener for, say, 2 minutes and use an alarm (set to
trigger two minutes after my hourly alarm is triggered) to remove
updates?  Is there a better way to solve this problem?

As far as it bombing, the application comes up on android then gives

comes up but is not operable. 

I have this warning in eclipse problems window, everything else it lists is

[android-developers] getting exception while connecting to server via bluetooth

[Ananda Krishna]

Hi,
I am trying to connect to a server in order to receive a file from the 
server.. with the help of bluetooth..
*The code is as shown below:*

private void connectServer() {
if(mBluetoothAdapter.isEnabled()){
  try{
  boolean startDiscovery = mBluetoothAdapter.startDiscovery();
  if(true == startDiscovery ){
device = 
BluetoothAdapter.getDefaultAdapter().getRemoteDevice(SERVER_MAC_ID);
Method m = device.getClass().getMethod("createRfcommSocket", new Class[] { 
int.class });
btSocket = (BluetoothSocket) m.invoke(device,Integer.valueOf(1));
mBluetoothAdapter.cancelDiscovery();
 btSocket.connect();
Toast.makeText(this,"Connected,Waiting to Receive 
Files...",Toast.LENGTH_LONG).show();
  } 
  }catch(Exception ex){
  Toast.makeText(this,"Connection 
Error:"+ex.getLocalizedMessage(),Toast.LENGTH_LONG).show();
  }finally{
try {
btSocket.close();
}catch (IOException e) {
Toast.makeText(this,"Connection Error:" + 
e.getLocalizedMessage(),Toast.LENGTH_LONG).show();
}
  }
}
}

I am getting the following exception at the highlighted line..
*java.io.IOException: [JSR82] connect: Connection is not created (failed or 
aborted).*
*
*
What is the mistake that i am doing...Any help in this regard will be 
appreciated.

The link contains code where a separate thread is started for each request.
Can I use it?

Can you please explain your comment?

Thanks!

you had a working single threaded serverthat started like this:

while(true){
socket =
serverSocket.accept();

why don't you change it to the multi threaded one?

Re: [android-developers] Re: Identifying HTTP Get requests in Android

[Archana]

Hi, 

Does the server in the 
hc.apache.org/httpcomponents-core-ga/httpcore/examples/org/apache/http/examples/ElementalHttpServer.java
 work 
in Android? 

When I try to use the constructor,

HttpService(HttpProcessor processor, ConnectionReuseStrategy connStrategy, 
HttpResponseFactory responseFactory, HttpRequestHandlerResolver 
handlerResolver, HttpParams params)


Eclipse says constructor is not defined. Eclipse gives a quick fix to 
change the constructor as:

HttpService(HttpProcessor proc, ConnectionReuseStrategy connStrategy, 
HttpResponseFactory responseFactory) 

How will I register the handler for my requests in this case? 

Thanks in advance!

[android-developers] Re: Can two applications that run in the same process have different STATIC object values?

[Massycat]

>From the second app, you can create a Context that is the same as that of 
the first app using createPackageContext(), 
http://developer.android.com/reference/android/content/Context.html#createPackageContext(java.lang.String,
 
int)
This Context will give access to the ClassLoader used by the first app 
(call getClassLoader() on the Context) if you include 
the CONTEXT_INCLUDE_CODE flag in the createPackageContext() call. Since 
both the apps are running in the same process the createPackageContext() 
call will not throw a SecurityException.
Within the second app, loading the common class through the acquired 
ClassLoader will give both apps access to the same static fields.

if the data in both tables is the same but differs only in column
names (for example you have a column fname in the first table and
first_name in the second) you could try set the column name in the
select statement:

select something as newColumnName...

if the data is totally different you have to override getView in your
adapter
