I am presently working on services.I have read many articles related to services.But one thing I don't understand is if we want our application to run in background how can we implement services without using Activities.

I am working on a small android project where it is necessary to share some data amongst several activities and a service that runs in a separate process. I would just like to know what are my options in terms of sharing data? Application class? IPC? File-based? Broadcasts?

I have been trying to find a discussion on the best way to handle a common sqlite database which is shared by multiple Activities (or multiple Activities and Services). This is all in the same application.
It seems that if each Activity has:

I have some shared preferences (user_id, email) that I want to access from services and classes that are not subclassed from Activity. I have been trying to implement this today and keep hitting roadblocks. In particular, when I try to access getSharedPreferences, I get a null pointer exception. My code is posted below. My goal here is to allow read access the shared preferences to objects and (potentially) services that aren't going to be directly exposed to the user.
<snip> public class MyPrefs extends Service {
public static final String PREFS_NAME = "MyPrefs";
private int user_id;
private String user_email;
private String user_password;
private Editor editor = null;
private SharedPreferences settings = null;
public MyPrefs () {
settings = this.getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
}
</snip>
this.getSharedPreferences line causes a null pointer exception.

Is it possible to stop all started services when the user hits the Home Button? I use:
startService(new Intent(ClassName.this, ClassName2.class));
stopService(new Intent(ClassName.this, ClassName2.class));
This means I will have to somehow add the 'stopService()' for 7+ of my app classes
I've researched this topic and I think there's 'onTerminate' but still not sure how this should be implemented.

Can someone tell me how to close all activities running under a tab?My initial activity does not need a tabbed view. Therefore, to initiate a tab for the next (remaining) activities, I call a class that extends TabActivity, from the first tab.All this class does is to assign and call activities based on the tab click.Currently, to close all activities i am using StartActivityforResult.But in this case, while calling activites from the TabHost, setContent does not accept a result code as a parameter.Help me to solve this one. My application is stranded in a blank screen before closing. i.e. in the TabActivity class.

I'm trying to understand the idea behind the Services. If it runs in the program's thread, why not create just a separate thread (or AsyncTask) to do the job? Can a service keep running in the background? For example, i want to create a task that will continuously be polling data from a server, even if the main application is not running. Can this be achieved with a Service?

In my ideal little dream world, I'd like to have a custom service running that handles network comms. Activities (e.g. UIs) then add listeners to it and it provides callbacks when anything interesting happens.
As it stands, I can't see how to do this in an appropriate way. OK, you can call bindService() and have a ServiceConnection implementation that monitors the service state. From there you can easily talk *to* the service whenever you desire, using serialisation over transactions, but I don't think that helps with communication initiated by the service.
The only way I know of doing what I want is by maintaining static collections of listeners on the service class, which doesn't strike me as good engineering.

When an app gets permission to access your Google account's Android services exactly what does it have access to? Is it authenticated to access all your google stuff including gmail?
For example, I installed Changelog Droid from the play store and it wants to access my Android services. I understand it probably only needs the permission to access my play store account to analyze my installed apps, but what else is open to it if I give it the permission?

I have a couple of services in my application which need to be marked as foreground to prevent them from being killed unnecessarily. Currently I am building my application with the 2.0 SDK but I have android:minSdkVersion="3" android:targetSdkVersion="5" in my manifest file so that I can support 1.5, 1.6 or 2.0 devices. I am currently using only the 1.5 APIs so that my application will run correctly on the 1.5 devices.
2.0 introduced a nicer startForground method that combines setting the foreground flag and starting a notification which can be used to control the service. The 2.0 documentation says that startForground replaces setForeground, and that due to the fact that many applications were mistakenly using setForeground without a notification that could be used to control and close down the service, that the older setForeground method had been changed so it no longer does anything on 2.0. I tried using the newer 2.0 interface but it caused an exception for phones running 1.5 or 1.6. So I am still using the older setForeground interface and calling notify separately. But it appears that since I am building with the 2.0 SDK the older interface isn't really preventing my services from being killed.

I know of the wonderful change from 2.1 to 2.2 that ActivityManager.restartPackage now doesn't do the dirty stuff anymore since it now calls killBackgroundProcesses. Nice on one side, but bad on the other side. Because of that Services are not killed anymore.See as well: http://groups.google.com/group/android-developers/browse_thread/threa.I am the developer of SleepTimer in the Android market and used restartPackage to stop Music Players to play music. I therefore killed the services. That worked well. But now with killBackgroundProcesses it doesn't work anymore. I added the new Permission to my manifest, but still the music remains running. Yes i know that google kind of wants that. But it breaks the possibility to stop the different music players from my app. Now my question: Is there another way to kill/stop other services (music player services) in API 8?

I am new to Android development and have trouble enabling / disabling the wifi & audio services. I get the appropriate manager instance using the getSystemService method. But I don't get any error when enabling wifi using:
wifiMgr.setWifiEnabled(true);
But the wifi is simply not turned on! Similarly I use
mAudio.setRingerMode(AudioManager.RINGER_MODE_SILENT);
or
mAudio.setRingerMode(AudioManager.RINGER_MODE_NORMAL);.....................

I wrote some reverse geocoding, geolocation and proximity alert routines for my little Android app. I took my Android out with me when running errands to test my routines; they're kinda hard to test from my couch. Half of them didn't work. What's the best way to debug something like this? Sprinkle a bunch of printf statements (or whatever you call them in Java) throughout the app? Log everything to the sdcard? Write a toggleable view (is that even possible?) that acts as a console? Faber Fedor Cloud Computing New Jersey http://cloudcomputingnj.com

I went through the Android introduction videos and in them an engineer from Google spoke of an open XMPP/gtalk service provided by Android, that developers could use to push messages out from a server to Android devices. I googled the forums and dug through the SDK samples, but could not find any code for these XMPP services. Also my search results only returned entries logged in the Jan 2008 time frame an earlier (I found this to be somewhat odd). Anyway, there was mention of a SMACK API that handles xmpp messaging, but I'm assuming that android has their own libraries for this.

I'm a little confused on how binding to services works. I understand using Context.startService() starts the service and that bindService doesn't call onStartCommand. But my understanding is that if I use startService, I have to explicitly stop the service. But I want the service to die if there are no more activities bound to it.My problem is that calling bindService never calls onServiceConnected(), so my Service binder object is null. Does the service have to be explicitly started in order to bind to it? If so, how does it know to terminate when nothing is binding to it anymore, and how do I know if it's started so I can know to use the bound object?
