[android-developers] Lazy loading in HorizontalScrollView to prevent Out of Memory issue
I want to add lazy loading feature to HorizontalScrollView, It has linearlayout as a child and i am addding to linearlayout, I am interested in listening to the event when the child view is out of the visibility area, I see in linearlayout implementation it does not call either dispatchViewVisibility or onDraw on child view , why i want that because bitmap attached to the child view can be recycled and create bitmap again when child view is visible (well that is a separate part ,How can i create that bitmap very fast, I am planning to use opengl for that) but the question is how can make such custom view. I can not use gallery view because it does not solve my purpose I saw that viewgroup has feature of dispatchingViewVisibility and dispatchOnDraw but not sure how to use that with HorizontalScrollView.? All i am doing to prevent Out of Memory issue Any suggestion and help would be appreciated thanks -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Lazy loading in HorizontalScrollView to prevent Out of Memory issue
@Drezden Your correct i am using larger number of images added as child view of LinearLayout which is a child view of HorizontalScrollView, Like OOM issue is happening at different number of images decoded from BitmapFactory on different devices like Google Nexus it is after 160 images , Xoom 253 images and so on. For decoding i am already using options and calculating inSampleSize only not inTempStorage(will it add any improvement if i use it?). Also i have cache that has soft reference to improve efficiency in terms of number of images decoded because i am recycling bitmap, but eventually it will crash due to OOM. thanks On Aug 26, 8:42 am, Drezden mmjohns...@gmail.com wrote: Are you loading a large number of images into your HorizontalScrollView? If so, then you are probably running out of memory from the Bitmap creation process. You need to subsample them so you aren't loading billboard sized images into your app, like this. BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 2; options.inTempStorage = new byte[16*1024]; Bitmap img = BitmapFactory.decodeStream(getContentResolver().openInputStream(imagePath), null,options); On Aug 26, 1:00 am, himanshu jain himanshu@gmail.com wrote: I want to add lazy loading feature to HorizontalScrollView, It has linearlayout as a child and i am addding to linearlayout, I am interested in listening to the event when the child view is out of the visibility area, I see in linearlayout implementation it does not call either dispatchViewVisibility or onDraw on child view , why i want that because bitmap attached to the child view can be recycled and create bitmap again when child view is visible (well that is a separate part ,How can i create that bitmap very fast, I am planning to use opengl for that) but the question is how can make such custom view.

[android-developers] Android bug/issue on IPv6
Hi all, I am not sure as Google mentioned IPv6 support is available on Android 1.6 or up , but i checked with 2.2 it even does not have link local IPv6 address whereas 3.0 has that. I tried to set up an environment to generate gloabal IPv6 but DHCP can assign IPv6 to other client except 3.0 HoneyComb which may have bug in native code ?. When i got gloabal IPv6 address from server i still not able to connect it says network unreachable ?.

Enable more logging and see if you can glean anything from it:
adb shell setprop log.tag.SyncManager VERBOSE
Plan B: I would put aside the sync adapter that you wrote, take
SampleSyncAdapter, make sure it works on the device, and then start morphing
it into what you need, making small incremental changes and retesting until
it stops working. Then you know where you made a mistake.

[android-developers] Re: Grab phonebook-contacts via ContactsContract-API
Hi Dmitri ,@LordAli3n I have couple of questions please spare some time or guide me direction 1) Can we use syncAdapter to get data of a row of raw_contact table if that row has been affected (i.e added/deleted/edited). I know ContentObserver notify whenever raw_content table changes in onChange() method but we dont know which row has been changed ( to put this in another way if we add how would we know and if deleted we still get it through deleted flag in raw_contact table but how about edited one??). 2) when we get notification in ContentObserver can we fire requestSync (Account account, String authority, Bundle extras) to start Sync ?? how we can get data of raw_contact affected by contact application using these to parameters . 3) Is sync started by ContentProvider API ?? whenever change to it happens ??. How?? does it pass any useful uri or data that has been changed in raw_contacts??. 4) How do we come to know if in the process of syncing something went wrong?? does it started again automatically??. thanks any help appreciated !!

I guess I just don't understand the requirements. I thought you were writing a sync adapter. Sync adapters all deal with their own accounts. Google sync adapter deals with google accounts, exchange adapter with exchange accounts and so on. If you are thinking of writing a sync adapter that would handle data already handled by some other sync adapter, it is probably a bad idea. The framework is not designed to have multiple sync adapters handling the same data: only one syncadapter can take advantage of data versioning. This why I suggested that if you are writing a sync adapter, you should introduce a new account type. This is how they are supposed to work by design.

[android-developers] How Sync Adapter works
Can Anyone gives a little bit more explanation like who initiate the the sync adapter if it is sync manager how it does that and what make it to do that.

If you have any idea please shed light on those question. I am trying to listen to raw_contacts database table through ContentObserver but i can only get the notification when database changes , what i really want which particular row of the table has changed , i know on change we can query about add ( i.e to query highest contact id entered into the database) and for delete check the delete flag set in the raw_contacts but how to know about which id had been updated ?.

Also my question is , can we really implement a service that runs in background indefinitely and give us update if it is available .If yes, then what parameters we should be aware of in sense of phone network ??. please advice. thank you On Feb 6, 10:59 am, Bob Kerns r...@acm.org wrote: This error indicates that some router along the path (possibly your local machine) has no route to the network you're trying to reach. If you're running on a rooted phone, you can run traceroute host to see the route to the host, if you have it; the busybox version works well. This will show where the problem lies. If the routing failure is on the local phone, 'route' will tell you about the local routing tables, if you're using the BusyBox version of 'route'. You can also get it via 'cat /proc/net/route', but in a much harder-to-understand format. Don't bother trying to figure out how to use the built-in version; it's incomplete. If it's not on the phone, it's not a phone problem. In any event, it's definitely not an application problem, but a network failure (assuming you're not trying to connect to some crazy address). It's something you need to handle gracefully. If the problem is not on the phone, and you're using wifi, you should be able to observe the problem from any host on that network (at least if it's getting the same default gateway, which would normally be the case). So I'd try that first, rather than dealing with the limited environment on the phone.

I tried to search about this behaviour online and found that too many

Is the above code right? Should make wl as a final variable? Does the

I am using a broadcastreceiver to start my service at boot up as well.
Any help would be appreciated.

have to kill the service to stop it from rebooting again and again...
I have no clue why that happens..

Can someone test this out please? If you have a service which
implements a wakelock (partial for my case), try enabling the call
forward option in the settings when the service is running in the
background...
and please let me know here if the phone keeps restarting..
Please help people...

Has anyone experienced this?

Hello Friends,
I have a service which holds on to a wakelock and the code is
similar
to this,
public class WakeLockService extends Service {
PowerManager.WakeLock wl;
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
public void onCreate() {
PowerManager pm = (PowerManager) getSystemService
(Context.POWER_SERVICE);
wl = pm.newWakeLock (PowerManager.PARTIAL_WAKE_LOCK,
My Tag);
wl.acquire();
}
public void onDestroy() {
wl.release();
}
For past two days, myphonehas been restarting randomly...Today it
was worse, it kept restarting untill I uninstalled the app.
I tried to search about this behaviour online and found that too
many
wakelocks may coz thephonetorestart. Can there be any other reason?
Is the above code right? Should make wl as a final variable? Does
the
service call onDestroy method whenphoneshuts down?
I am using a broadcastreceiver to start my service at boot up as
well.
Any help would be appreciated.
Thank You So Much

[android-developers] Re: RssFeed Update
@Raghavendra
Here is my code i used wake_lock and release it but it seems not to be
working :-
abstract public class WakefulIntentService extends IntentService {
abstract void doWakefulWork(Intent intent);
public static final String LOCK_NAME_STATIC =
MyCompany.DdayService.Static;
private static PowerManager.WakeLock lockStatic = null;
public static void acquireStaticLock(Context context) {
getLock(context).acquire();
}
synchronized private static PowerManager.WakeLock getLock(Context
context) {
if (lockStatic == null) {
PowerManager mgr = (PowerManager) context
.getSystemService(Context.POWER_SERVICE);
lockStatic =
mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
LOCK_NAME_STATIC);
lockStatic.setReferenceCounted(true);
}
return (lockStatic);
}
public WakefulIntentService(String name) {
super(name);
}
@Override
final protected void onHandleIntent(Intent intent) {
doWakefulWork(intent);
getLock(this).release();
}
}
I used alram manger for repeating the process that manager call
onAlarmReceiver which calls my service which had dowakfulwork
function
but after sometimes it throws network unreachable may be due to wifi
network not available, I have a question can we really implement
background service that updates indefinitely even if phone is in sleep
mode .?
thanks

Hi,
Have you used partial wake lock? I got the similar problem in my
app. I fixed it by using wake lock. Following is my code snippet. May
be this will help you.
PowerManager.WakeLock wl;
try {
PowerManager pm = (PowerManager) context
.getSystemService(Context.POWER_SERVICE);
wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
Nyros);
if (wl != null)
wl.acquire();
//do your stuff here
} catch (Exception ex) {
} finally {
if (wl != null)
wl.release();
}
Thanks Regards,
Raghavendra K.

[android-developers] RssFeed Update
HI Folks I am currently developing RssFeed app , i have one issue .I want to implement background service ,but what happen after some times it throughs Scoket.net exception,this was due to fact wifi goes in sleep mode and my app can not connect to server,In order to rid of this i thought of using wake_lock but this may not work because wifi can go to sleep mode before i get wake_lock. Is there way to keep wifi awake or this is the only solution for my issue. I want to implement service indefinitely not when my app is active. any help appreciated -- You received this message because you are subscribed to the Google Groups Android Developers group.
