[android-developers] Re: LocationManager - getLastKnownLocation() - NullPointer Exception

2008-08-22 Thread code_android_festival_way 

So I got it working now. I'm using the service thread to get the
location.

And that's the way I did it:

http://paste.pocoo.org/show/b67L69qf5QDNtq1pTzZz/

It works pretty fine. But you should add some timeout to the
condition.await() of the background thread.

 The LocationManager.request*Updates methods must be called from a
 Looper thread, such as the main thread of an Activity. Additional
 method variants have been added that take an explicit Looper argument
 to allow for use outside of a main thread.

 This could be the solution for my problem. Now I have to understand
 what that means for me. If someone knows the solution I'm looking
 forward reading it. :-)

In M5 I only called getCurrentLocation() and everything was fine.
Now as the methode is gone I need to set this update request to the
LocationManager in order to get a not outdatet position. To achieve
that I have to loop inside my geo location class and wait for the
Listener to be invoked in order to be able to return some location
from the geo location class.

   Off the cuff, I suspect you will need to have whatever code uses
   GeoProvider switch to supporting asynchronous delivery of location data.
   It may no longer be possible to synchronously get your current position.

   But, I won't be diving into the new mapping code until this weekend at
   the earliest, so I can't comment on how better to handle your situation
   until then.

   If you're still struggling come Monday, send me an email to remind me to
   post something.

Thank you for your reponse. I'm trying to implement the

problem. I've implemented the LocationListener but always get the
following LogCat error.

Getting the status bar icon is a good sign -- that means the
GPS_PROVIDER is receiving the updates.

I've got one more cheap/easy idea for you. I'm not sure if 0 is a
valid limit to set for the refresh time / distance. Try setting it to
1000 (milliseconds) and 1 (meter) to see if that helps.

Sorry, I haven't looked at your code. But you may be right on this.

Android applications have the main event thread, plus any secondary 
threads you create on your own. Listener callbacks, AFAIK, happen on the 
main event thread, which is why you can update UI elements without muss 
or fuss. If your while loop is also on the main event thread, you never 
release that thread, and hence your listeners may never be called.

 Well I'm calling my geo class in a thread that was started by a

 order to get the listener working?

  You can disable the updates after the first return if you want to, in

   Firstly I got the question why I can't get the currentlocationany
   more. I don't need repeating updates of my position I just need the
   currentlocation. At the moment I'm using getLastKnownLocation() but I
   would assume that this position could be very outdated.
 
   Furthermore the method getLastKnownLocation() returns me aLocation
   object that is null. Here is the code that I'm using at the moment:
 
   LocationManager lM =
   (LocationManager)context.getSystemService(context.LOCATION_SERVICE);
   LocationProvider lP = lM.getProvider(gps);
  Locationloc = lM.getLastKnownLocation(lP.getName());
   String[]location=
   {String.valueOf(loc.getLongitude()),String.valueOf(loc.getLatitude())};
 
   I've added the following permission to my manifest file:
 
   uses-permission
   android:name=android.permission.ACCESS_LOCATION /
   uses-permission
   android:name=android.permission.ACCESS_FINE_LOCATION /
   uses-permission  android:name=android.permission.ACCESS_GPS /
   uses-permission
   android:name=android.permission.ACCESS_MOCK_LOCATION /
 
   But I'm always getting a Nullpointer Exception using theLocation. (so
   theLocationreturned is null)
 
   Could you give me a hint how I could achieve to get my current/
   lastKnownlocationin 0.9? (in M5 everything was fine)
 
   Looking forward getting your answers.
 
   Regards and happy coding!

2008-08-21 Thread Reto 

I agree. There's definitely a very good chance that the while loop is
blocking the listener callback.

Note: I believe he's running the whole lot in a new thread (and
forcing the update requests to fire on that same thread) rather than
the main event thread, but it still turns in to the same problem in
the end.

[android-developers] Re: LocationManager - getLastKnownLocation() - NullPointer Exception

2008-08-21 Thread code_android_festival_way 

Well I'm starting a service from my main thread. (some activity) In
the service I'm starting a new thread and do some work. (communication
with external APIs (flickr)) While that work I need the position of
the device. To get the position I had written this class:

http://paste.pocoo.org/show/80ypWR00yHnHRz9pN7mc/

In M5 I only called getCurrentLocation() and everything was fine.
Now as the methode is gone I need to set this update request to the
LocationManager in order to get a not outdatet position. To achieve
that I have to loop inside my geo location class and wait for the
Listener to be invoked in order to be able to return some location
from the geo location class.

Now I don't really know how to do that the right way. (not blocking
the thread) I would appreciate every hint that you could give me. I
dont really know how to handle that situation.

Best Regards!

Off the cuff, I suspect you will need to have whatever code uses 
GeoProvider switch to supporting asynchronous delivery of location data. 
It may no longer be possible to synchronously get your current position.

But, I won't be diving into the new mapping code until this weekend at 
the earliest, so I can't comment on how better to handle your situation 
until then.

If you're still struggling come Monday, send me an email to remind me to 
post something.

Thank you for your response. I will try handling this in a different

[android-developers] Re: LocationManager - getLastKnownLocation() - NullPointer Exception

2008-08-21 Thread code_android_festival_way 

The LocationManager.request*Updates methods must be called from a
Looper thread, such as the main thread of an Activity. Additional
method variants have been added that take an explicit Looper argument
to allow for use outside of a main thread.

This could be the solution for my problem. Now I have to understand
what that means for me. If someone knows the solution I'm looking
forward reading it. :-)

Regards!
