Question

I had this simple doubt.
I have to display a progress dialog when the phone is getting location update.


Do I need to do this in a separate thread or does getLastKnownLocation already run in a separate thread.
If it doesnt can anyone please post a small sample code, the most effective way to do this?
I went through the android api source and did not succeed in finding out the working.

getLastKnownLocation runs synchronously and it doesn’t actually get the current location (which is what you probably want). Here is the documentation: http://developer.android.com/reference/android/location/LocationManager.html#getLastKnownLocation%28java.lang.String%29

The highlights:

Returns a Location indicating the data from the last known location
fix obtained from the given provider. This can be done without
starting the provider. Note that this location could be out-of-date,
for example if the device was turned off and moved to another
location.

If the provider is currently disabled, null is returned.

What you probably want is something more along the lines of this question: displaying progress dialog at the start of a gps application
