In one application, when an activity start I use the getLastKnownLocation to get the last know position, using something like: Location position=mlocManager.getLastKnownLocation(mlocManager.getBestProvider(new Criteria(), true)); (in the onCreate)
After this, my application register a listener in the onResume() (and removes it in the onPause()), something like:........................

I have read all the posts about this topic and I understand the arguments being made. However, I would like to know how Google Maps can return my *current* location yet while driving the same stretch of road, the Android API often (not always) gives me a last known location that was miles back. I need to be able to rely on the API to provide me with a *current location* and I have tried all the tricks being proposed here and elsewhere. Is there lower level code someplace that could ping the phone's radio for a "fresh fix?"
View 13 Replies View RelatedI am facing with problem related to the Location API.
I tried the following code:
CODE:...................
I'm having no luck getting getLastKnownLocation to return a non-null value in the Android emulator running in Eclipse. The following call always returns null:
locationManager.getLastKnownLocation(bestProvider);
(bestprovider is "gps")
In the intent's onCreate method I spawn a thread that calls requestFirstUpdate(). The onLocationChanged method fires so I presume the location was updated (I use the location section of the DDMS to push out a location first)..................
I can't display my map on android emulator. i have, locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); location = locationManager.getLastKnownLocation("gps"); After those lines,the Log shows null for location instead of the object location
View 4 Replies View RelatedSo I'm trying to sample the gps coordinates just once in an application. I don't want to create a LocationListener object to constantly get gps updates. I want to wait until receiving the coordinates, and then proceed on to another task.
Here is a code snippet
CODE:.................
The loc variable is always null in the emulator. I tried using the command "geo fix latitude longitude" to set it, and also I tried using the DDMS way of setting it. Neither method had any effect on the code. Also the snippet isn't causing any exceptions.
On my htc i was looking through display, i see g sensor calibration and i perform this calibration and after i do so the screen seems to have a delay when switch from the horizontal position to the vertical position. its weird because when i switch to the phone horizontally it switch normally and responds fast. but when i switch back to vertically it takes almost 7 seconds to actually switch back, sometimes it switch within 2 or 3 secs but never as quick as switching horizontally.

If you're already updated, shut down and repower (soft reboot) should do the trick. I actually updated my phone and after it started to do this. I restarted the phone plenty of times i even took the battery out for 30 seconds. It only does it when im texting on the browser, basically everything but the camera. He camera screen rotation is perfect. I even rooted the phone but i havent figured out how to use the root to fix the problem. Should i do a firmware update? Because i just did the htc software update.
I'm using
CODE:......
To retrieve the current location at the start-up of my application.
As the Android documentation states, this location can be "out-of-date", since the method returns the location when the GPS was used the last time.
How can I actively request the current location from the GPS? I thought about using LocationListener, however that might be a bit of an overkill, since I only need the location once (at the start of my app).
Do the Android users have the chance to reset the NetworkProvider, so that the location will be null?
I came up with the idea, that its only possible to have that location null, after starting the device the very first time. But also than google will check the location right away for my opinion.
Sure, I'm implementing a default location for this rare case. I just want to know how seldom this case is.
I tried using both getLastKnownLocation and requestLocationUpdates to get GPS coordinates from emulator.

After that, i tried:

View 4 Replies View RelatedI have a listview displaying my data.Ok. I want to set the scroll position in a position of my choice, but I just cant do it. I used :
myListView.setSelection( anyPosition ); myListView.setSelected(true); and has not worked. I also tried : myListView.scrollTo(0, PositionY); and myListView.scroolBy(0, PositionY);
and there's a strange behavior, this two methods doesn't put the scrool in the "PositionY", it made the "PositionY" be the first position in the list, cutting everything that exist before.
I have a long listView that the user scrolls around and then returns to the previous menu. What I want is that when the user opens this list View again the list to be scrolled to where the it was previously left. Any ideas on how this can be achieved ?

The structure is the following:

My customRelativeLayout at the bottom of the XML has a XML layout too:

My CustomRelativeLayout:
CODE:.....................
What I want to do: I want to be able to change the position of my CustomRelativeLayout. It should be follow my touch. Its smaller than the SurfaceView and should "slide" above following my touch...
There are two problems:
The onTouchListener bind to mLinearLayout (in CustomRelativeLayout) is only triggered once and only for ACTION_DOWN. I see the log output only once The note never changes the position, it is never redrawn with the changed matrix... I see the output stated in onDraw never after the touch happened.
First might be because the SurfaceView also handles touch events. But I thought if the CustomRelativeLayout handles it first, it should work.

CODE:..................
I also found a bug/feature/issue, which is absolutely new for me: When I remove the background in my note root element (which is currently transparent) the note is only visible within the 200dp width/height I have set in the inner LinearLayout. So its not fill_parent, its wrap_content even as I set it to fill_parent. So layout_width and layout_height only use the given fill_parent when a background is set...
I'm trying to do something which seems simple. I want to have a map view, with a menu that slides up from the bottom of the screen where settings (for overlay) can be adjusted. However when I use a TranslateAnimation to affect the y position of the LinearLayout (which holds the menu), the buttons in the LinearLayout move, but there "hit area" stays in the same position as they were before the animation.
CODE:.........
I've also looked into tweening the view's marginTop value, but haven't even been able to determine how that would be done.
