Android :: GetLastKnownLocation() Always Returns Null
May 21, 2009I'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)..................
Android :: Location.getLastKnownLocation Returns Null
Oct 17, 2009I 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

Oct 22, 2009So 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.
Android :: How Often Does GetLastKnownLocation(LocationManager.NETWORK_PROVIDER) Return Null
Sep 10, 2010Do 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.

Dec 2, 2009I 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?"

Nov 12, 2010In 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)

Android :: GetLastKnownLocation Out-of-date - How To Force Location Refresh
Jan 13, 2010I'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).

Android :: Why Does LocationListener Become Null?
Jan 28, 2010I am having issues regarding a LocationListener in my Service called myService.
Here is my code:

provider = locationManager.getBestProvider(criteria, true);
locationListener = (LocationListener) new MyLocationListener();

Android :: Use Null Layout ?
Mar 8, 2010Is there an equivalent to Java's null layout in Android? Basically I want to specify the x and y coordinates of each component and not have the layout manager choose where they go. They will be within a scroll pane so it doesn't matter whether they fit on the screen.
I know null layouts are generally not a good idea but I have a special case where I need it. I'm porting a Java TV guide app and the program grid is made up of JLabels. The program dynamically generates them all, setting the x and y coords based on start/end time and channel. Each program could start and end at any time so as far as I know a table layout won't work.

Android :: Geocoder API - Returns A Null Value
Aug 26, 2009I am having a real hard time with the geocoder API of android sdk 1.5rc2. In my app I am trying to get the addresses corresponding to a location name by using the getFromLocationName method of the Geocoder class. But the problem is whenever I call this method it returns a null value. I have also pushed a geodb file containing some fake addresses at 'data/misc/location' directory in the phone.
The format of the data in the geodb file is as follows :
address 1 latitude "38.898763" longitude "-77.036655" line 0 "1600 Pennsylvania Ave NW" line 1 "Washington, DC 20006" locality "Washington" region "DC" postalCode "20006" countryCode "US" countryName "United States"
and following is the code snippet : Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses=geocoder.getFromLocationName("1600 Pennsylvania", 10);

Android :: GetRingtone Returns Null
Feb 1, 2009why RingtoneManager.getRingtone(this, Settings.System.DEFAULT_RINGTONE_URI); always returns null when launching from my activity? Shouldn't it return some object which is System.DEFAULT_RINGTONE_URI, which I can then play()? Is there any small example of code which shows how to play Ringtone from Activity? MediaPlayer way also not works. MediaPlayer.create(this, Settings.System.DEFAULT_RINGTONE_URI)
simply crashes with:

First Android App And Null Bundle Object
Oct 29, 2012I've gone through the Notepad Tutorials and they are all working on my virtual device. I am now stuck in the midst of trying to write my own Android app.
My setup:
Windows 7 SP 1 64-bit
Eclipse Indigo Service Release 2
Android Development Tools 16.0.1.v201112150204-238534
Android Virtual Device Platform 2.3.3, API Level 10, CPU/ABI ARM (armeabi)
The app is about as simple as they come - you enter a number, it divides it by another number and displays the result.Here is the code involved:
AndroidManifest.xml:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.driving"
android:versionCode="1"
android:versionName="1.0" >
[code]...
By the time DrivingTimeEstimator's onCreate() method gets executed, the Bundle object (savedInstanceState) is null (which I'm guessing is what leads to mMiles being null, which throws a NullPointerException and kills everything).
