[android-developers] Access Point Change detection (WiFi)

[android-developers] GPS information with logcat
Hello, I’m trying to see if the assistance data is injected into the GPS by examining the logcat but I’m not able to know where the problem is. As I can see in logcat messages, Android fist tries to connect with the SUPL server but it fails, whereas the NTP time injection is well done. Finally, a xtra data download request is done (my devices has a Qualcomm chip) but there is no message to see whether it is well done or not. Logcat messages: // SUPL A-GPS D/GpsLocationProvider( 96): set_capabilities_callback: 7 D/ lib_locapi( 96): loc_eng_init called, client id = 0 D/ lib_locapi( 96): loc_eng_set_default_agps_server, type = 1, hostname = supl.google.com, port = 7276 D/lib_locapi( 96): loc_eng_process_deferred_action started D/lib_locapi( 96): Setting GPS privacy lock to RPC_LOC_LOCK_NONE D/lib_locapi( 96): loc_eng_set_gps_lock mode, client = 0, lock_type = 1 D/lib_locapi( 96): loc_eng_set_gps_lock mode failed // NTP D/GpsLocationProvider( 96): NTP server returned: 1306739478749 (Mon May 30 09:11:18 GMT+02:00 2011) reference: 38652 certainty: 73 system time offset: 12419 D/lib_locapi( 96): loc_eng_inject_time, uncertainty = 73 // XTRA DATA Qualcomm D/lib_locapi( 96): loc_event_cb: xtra download requst Is there any way to get more information related with the GPS behavior?

[android-developers] Binding a remote service through the application class
Hello, I am developing an application compose by: 4 activities, one application class (Global) and a remote service with provides the data shown in the active activity (the same data is needed for all activities). The application class (Global) is where I define and interact with objects that are used by all the activities. Moreover, as it is only instantiated ones at the beginning of the application, I also do things that must be done only once: opening a database at the beginning (the same database is used by both, the remote process and the activities). As the data returned by the remote service must be redirected to the current activity, I bindService() and receive the data from the service in the Global class. I start the service in the onCreate of Global class in order to get the data as soon as possible. I thought that this Global class was only instantiated once during the whole application (at the beginning) but when I bindService(), this class is instantiated again. Therefore, the onCreate is again executed and another process is started. Can someone tell me the correct way no do this? Is It possible to define a common class (with common objects) that is only instantiated once and valid for both, activities and the remote service. Another thing that I would like to know is if is better to use Singleton classes or application classes.

[android-developers] Re: Binding a remote service through the application class
Thank you so much, Mark. I am using a bound service in a remote process and I have already solve the comunication between 2 processes (the application shown and the service). I think that my service must be implemented in a separate process because it implements a CPU intensive work and it used to block the GUI when I used AsyncTask to refresh the GUI, maybe there is other alternatives. Any sugerences? The good point of the Application class is that it is instanciated and onCreated before any other component of the application. thank you very much again.

[android-developers] Re: BroadcastReceivers and orientation changes
Thanks Mark, I no sure about the difference between registering the
event on the activity or registering it on the application context, can
´t I pass the broadcastReceiver object thought
onRetainNonConfigurationInstance() if I made it on the activity?
Another problem would be what happends if I have another listener
(i.e. GPS location update listenes) in the same activity, with this
solution is not posible to pass 2 different objects(listeners) to the
onRetainNonConfigurationInstance, any solution?
Thank you so much.

Rather than calling registerReceiver() on the Activity, call it on the
Application context via getApplicationContext().registerReceiver().
Then, pass the receiver object via onRetainNonConfigurationInstance(),
so you unregister the same receiver when you are done.
