[android-developers] Re: how to achieve the accuracy of google navigation
I can see how extrapolating would yield good results if you have a small delay between reported position real position, e.g. the 1s update rate of most GPS receivers. What I can't see however, is how you could make that work with larger delays, especially for large accelerations. Say for example you drive on a straight road at 3m/s, accelerate with 2m/s2, and we exampime multiple delays. We can extrapolate from the last known location at constant speed over that delay and compare position to where we really are. 1s delay: const speed: 3m reality: 4m error: 33% 2s delay const speed: 6m reality: 10m error: 66% 4s delay: const speed: 12m reality: 28m error: 133% I've measured delays varying from 1 to 4 seconds several times, and yet Google Nav manages to position the car at the exact location. It can't use map data to correct its position, since we're on a straight road. So that must mean that it uses sensor data, right? Or am I missing something? On 08/03/2012 08:47 PM, Nadeem Hasan wrote: That would be extrapolation. And that is actually the exact reason why the GPS lags on exits if they are off-route because it has extrapolated your position based on your route till the next actual GPS location update arrives. I have seen this behaviour with my Garmin device too when I decide not to follow the route.

That of course only works when you have something like a graph / vector representation of the streets and know how they are connected and what orientation they have. It is also pretty common that even Google Navigation is off, especially on highways with exits. Sometimes the navigation draws the car following the highway even though you are already leaving on an exit.

My test application subscribes to location updates and draws a car symbol in a map, the map is centered to the location of the car rotates according to the bearing of the location (exactly like google maps on android does). I noticed that when up to speed, the positions don't match with reality, they lag behind considerably. When I cross a street at 90km/h for example, it will take a few seconds before the car on the map is also crossing that street. It isn't an error in the map data, because when I'm standing still, the car gets drawn on the correct location. Google maps for android shows exactly the same behavior. The position of the car in Google Navigate on the other hand matches reality rather closely. I've noticed that the position updates are a lot smoother as well. (10Hz rather than the 1Hz updates which you get from GPS) My question is: how do they do it? What I can think of is: - using the phone's sensors (gyro accelero) together with a kalman filter or similar. But I can't see how you could make that work for every phone, since not all phones have these sensors. - interpolating, but in that case I would expect overshooting when there is a sudden stop or a sharp corner Thanks in advance.

[android-developers] Contact API problem with save datas Options
I'm facing a basic problem but i didn't find any tutorial in order to

So i write a two implementation of ContactApi, one for 1.5, 1.6 and an
other for new api version.
Here is the list of problem I'm facing with.
With new api, nothing. All works fine, backing up contacts works well.
But with older api I'm not able to backing up some datas :
Email Datas (able to read, but not able to save)
IM datas (able to read, but not able to save)
Notes (able to read the first note, if many notes, I lost datas, same
things for backup)

[android-developers] Re: Some confusion on resource IDs
You can declare IDs in your res/values/resources.xml file, like this: resources item type=id name=common_control_01/ item type=id name=common_control_02/ /resources Then, refer to the id in your layout simply with @id/common_control_01 If you have a bunch of common IDs, this might be a good approach.

What I'm just seeing is that if I assign the IDs using @+id/name, I'll have to have a unique name for every widget on every screen since all the symbols get defined in one big R.java file. Or can I just generate the definitions once in one of the XML files and then reference them in the other layout files? For example, if I have a TextView that I'd like to call surname in multiple layout files, can I declare it one of the files using @+id/surname and then simply use @id/surname in the other files? I assume that as long as all the IDs are unique within a layout file, all is OK. No, you can't declare it that way. However, if you use @+id/surname multiple times, only one R.id.surname entry goes in R.java. -- Mark Murphy (a Commons Guy)http://commonsware.com|http://github.com/commonsguyhttp://commonsware.com/blog|http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 3.1 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Displaying parameterized text in AlertDialog
WIth managed dialogs, onCreateDialog is called only the first time the dialog is shown. If you want to show the dialog again and display a message that's different from when the dialog was created, override onPrepareDialog and call setMessage from there (based on the dialog's id if necessary).

I'd like to show the user an AlertDialog with varying messages (for example, Number of files: some number). I tried different approaches, but none worked for me. When using managed dialogs, I can only pass a dialog id to onCreateDialog (I know this was fixed in API level 8, but I need compatibility with API level 3). I cannot pass text parameters such as some number. So this approach seems to work for static messages only. When creating and showing the AlertDialog on my own, I have to explicitly dismiss the dialog in the Activity method onDestroy (otherwise I'd get a window leaked error). With this approach I would have to store references to all open dialogs in an activity, which seems too tedious for such a simple task. Another problem is that I would have to implement dialog persistence at configuration changes on my own. Did I miss something?

[android-developers] Re: Question about contact management (register and lookUpKey)
I Finally found a solution for the second problem :
I was creating the contact in severals times (create RawContact and
add all data of contact after)
So yet I'm using this code :
ArrayListContentProviderOperation ops = new
ArrayListContentProviderOperation();
ops.add(ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI)
// /
.withValue(ContactsContract.RawContacts.ACCOUNT_TYPE,
contact.getAccounts().get(0)[0]) //
.withValue(ContactsContract.RawContacts.ACCOUNT_NAME,
contact.getAccounts().get(0)[1]) //
.build());
ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI) //
.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID,
0) //
.withValue(ContactsContract.Data.MIMETYPE,
ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE) //
.withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME,
contact.getDisplayName()) //
.build());
if (contact.getPhone() != null contact.getPhone().size()
0) {
for (Phone phone : contact.getPhone()) {
ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI) //
.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID,
0) //
.withValue(ContactsContract.Data.MIMETYPE,
ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE) //
.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER,
phone.getNumber()) //
.withValue(ContactsContract.CommonDataKinds.Phone.TYPE,
phone.getType()) //
.withValue(ContactsContract.CommonDataKinds.Phone.LABEL,
phone.getLabel()) //
.build());
}
}
And now I have a lookupKey valuated :) !

You are setting the padding to be 36 pixels, which is going to be too

scales assets/dimensions/etc. up by 1.5, meaning a 20x20 image becomes

reason. The easiest solution for you is to define your generic view
inside an XML layout file and inflate it at runtime. And make sure to
use the dip unit when specifying the padding or the height of the
generic view (your height of 64 will also be an issue on a high

I also try to copy the inner class available in ExpandableList1 for
adapter and I launch it into my activity and I also have the problem
see on photo
What I am doing wrong... ? I am forced to manage density into my
adapters in order to adjust the padding ?

I have a G1 and mLocationManager01.removeUpdates
(mLocationListener01); work well but in emulator in version 1.6 and
2.0 the gps doesn't stop... And someone report me the same issue
concerning my application with droid phone
What I am doing wrong ?

hi all,
it' so strange about close gps location manager,
the gps signal dosen't stop.
my code is:
==code===
public class g extends MapActivity{
private LocationManager mLocationManager01;
�...@override
protected void onCreate(Bundle savedInstanceState)
{
mLocationManager01 = (LocationManager)getSystemService
(Context.LOCATION_SERVICE);
.
}}
and my stop code is:
mLocationManager01.removeUpdates(mLocationListener01);//stop gps
service
however,
this stop code I write into the onDetroy(),onPause(),onStop(),finish
(),
but sometimes the gps signal will not stop expectly.
something wrong??
thanks!
