Re: [android-developers] Re: GPS Background Service Stops Receiving Updates
Hi, For - 1. Check if GPS is supported & if LocationManger is disabled, if so prompt the user to re-enable it, be kind & take them directly to the applicable Android->Setting screen to do this. (See 4 also). 2. Where possible I ignore LocationManager & use the raw GPS NMEA data, http://developer.android.com/reference/android/location/LocationManager.html#addNmeaListener(android.location.GpsStatus.NmeaListener) but be aware some older devices don't support this such as Motorola Defy+ 3. Date & Time from GPS is UTC unless you localise it, (but see 2.) 4. I guess this may happen, perhaps that is related to 1, or the device does not have onboard GPS receiver (eg HP Slate 7 tablet) - then offer to connect to an external Bluetooth GPS receiver & use that instead. 5. That is never an issue if you 'key' the lat lon data with GPS date/time stamps, if duplicate lat lon is an issue in some upload then your server app logic is probably incorrect.

Re: [android-developers] Simple PagerAdapter does not display views
Yes, and that's what's so frustrating, Kastya. The breakpoints appear to indicate that everything is working, as does the fact that it responds to a swipe. For example, if I start it off by calling ViewPager with setCurrentItem(3), my instantiateItem is called with position=3, followed by position==2 and 4 (the views to either side). When swiping to go to the right, destroyItem is called with position=2 and instantiateItem position=5 as expected. isViewFromObject is called numerous times and I correctly return true or false. Since the data in the adapter never changes, getItemPosition always returns POSITION_UNCHANGED per the specs. I feel like there is something I'm missing that is failing to make my views "visible", or else there is some undocumented "feature" since they do not provide much info for using the base PagerAdapter (all the samples are using FragmentPagerAdapter or FragmentStatePagerAdapter. I am now considering changing over to use fragments instead of simple views since I know that works even though to me it seems less efficient in this case. Thanks for your response in any case! -- Doug On Monday, November 24, 2014 5:09:31 PM UTC-5, Kostya Vasilyev wrote: > > Did you properly implement the adapter's isViewFromObject? > > How about getItemPosition? > > -- K > > > -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Is it possible, that Android kills a service inside an app?
Hey guys, let's imagine we have an app with a service and an activity inside. Both components live in a same process, our service is started (in terms of Android) and a user does some interaction with an activity. Eventually our app goes to background. My question is, whether is it possible, under certain conditions (low memory, timeout, etc), that Android "kills" our started service separately, without killing entire process?

Re: [android-developers] Re: GPS Background Service Stops Receiving Updates
Party is not over you might find the issue like 1. Though the GPS and Network is disable, The Location manger returns Network provider and returns the invalid/long distance lat and long data. 2.Sometimes, though you put your tablet/application in one place, the Network/GPS Provider will return the lat longs of the different location. 3.Though you mention the distance and time, the Network provider return the data of Asia pacific. 4.At a times, you might also get the locationmanager object as null, though it work the full day but it fails at one point. 5.and also, what is the logic you have put to avoid the duplicate lat and long to be uploaded. I had the situation earlier and i have shared you my experience.

[android-developers] Same database cursor in ListFragment and ViewPager
Hi guys, I have a ListFragment where I load a Cursor through a Loader in onCreateLoader(int i, Bundle bundle). If I click on a ListItem then I replace the Fragment to another Fragment "DetailsPageSlider" and set as argument position and count. In my FragmentStateAdapter in getItem(int position) I create my Details Fragment which needs the database _id as argument. So now I have to match the "position" in getItem with the database _id! How I could solve that problem? 1) Should I load exactly the same cursor for my FragmentStatePagerAdapter to get the database _id through the position. 2) Or Is it possible to use the same Cursor in my ListFragment and also in my FragmentStatePagerAdapter? 3) Or any other ideas? greets Markus -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Re: [android-developers] Re: GPS Background Service Stops Receiving Updates
Hi, re - I am holding the home button and the list of apps comes up and I swipe away my app to kill it. This is what others have mentioned above. I don't know if this is samsung only or not. Maybe this method is supposed to kill all running services and processes of the app and is not a good way to test. Ok I think you are referring to the rectangular 'Recent Apps' button, not the Home button, but I get what you mean about swiping to close a recent Activity from that list. And yes, what Treking said about StartForeground. Regards On Tuesday, November 25, 2014 7:29:07 AM UTC+11, Tony Pitman wrote: > > It looks like calling startForeground was the key.
