I am trying to reduce the battery consumption on my Note. I have several apps which use the GPS but the gpsd process is being called quite a lot, even when I am not using any GPS app.
Simple question - now that I have established which service is being called (using better battery stats) is there a way to determine which app(s) are using it? GT-N7000

I'm getting beat down with GTALK_ASYNC_CONN wakelocks while on my work's AP.... the specific WL is :gtalk_async_conn com.google.android.gsf.gtalkservice.androidendpoint.... something everyone has been complaining about recently, and I never saw it until recently (now that I got up to 4.1.2 a short time ago.
Is there a way to determine exactly who is generating that WL? It's not related to GTALK, as the WL name incorrectly leads us to believe, but it must be google, and I only see it fire when the Wi-Fi is connected and in use. It's non-existent when I'm on Mobile. It comes and goes, sometimes chugging wake time like its cheap beer, othertimes it's dormant, and I haven't been able to figure out who is using it based on the context of when it occurs.
There HAS to be a log or something somewhere that says process X is responsible.
At a certain point in my program, when I'm completely done with my service, my activity executes unbindService() and stopService() -- yet the process persists. I can tell that it persists because I run "ps" in "adb -e shell":
CODE:.............
"adb logcat", I can show you the sequence of events:
ACTIVITY: context.unbindService(serviceConnection);
SERVICE: onUnbind();
ACTIVITY: stopService(serviceIntent); & returns true!
SERVICE: onDestroy();
First, my activity calls unbindService(serviceConnection). According to the documentation, unbindService() will "Disconnect from an application service. You will no longer receive calls as the service is restarted, and the service is now allowed to stop at any time." So that is fine, and it is happening.
Appropriately, we see the onUnbind() call happen on the service side. According to the documentation, onUnbind() is called when "all clients have disconnected from a particular interface published by the service." So this confirms the correct service connection is being passed, and that the service is responding accordingly.
Next, my activity calls stopService(serviceIntent), and returns true. According to the documentation, stopService() does the following: "If there is a service matching the given Intent that is already running, then it is stopped and true is returned; else false is returned." Again, this is happening and returning true.
In response, the service's onDestroy() method is called. According to the documentation, onDestroy() is "Called by the system to notify a Service that it is no longer used and is being removed. The service should clean up any resources it holds (threads, registered receivers, etc) at this point. Upon return, there will be no more calls in to this Service object and it is effectively dead."
At this point I expect the process to disappear from the process table. Yet it remains indefinitely. But why?
Also, the process is so persistent that I can bind to it again, and I see that it is the same exact process responding because the PID (process ID) is the same!

I'd like this to just sit and do nothing until any application wants to give it data to send. That's all well and good.I have register an intent filter and the usual stuff and can process the data. But I want to process the data coming from different activities in different threads (subsequent calls from the same application will be computed on the same thread).Is there a way to get the calling package or app or whatever? I'd prefer not to require passing in an identifier as an extra to prevent spoofing. (It's not a serious security concern, it's just each application needs its data processed in the order that it's received.)

I'm pretty sure that android services are going to be the end of me.I have almost no hair left after the last few days.At first I was having a heck of a time getting the service to bind on an onclick of a button, got that straightened out from help here yesterday. Now I actually want the service to bind in the onCreate() method of the activity. That part is no problem, works as intended.My service is actually a socket service to connect TCP sockets to a socket server that I wrote.If I put the call to the method from the bound service mBoundService.StartSocketServer() inside a button click, bingo, works great. But I need this to fire up immediately when the activity loads, so directly under my bindService() call within my onCreate() method of the activity.When I place the call to start the socket inside my onCreate() I get a force-close.
This method (StartSocketServer()) spawns a new thread then opens the socket on that thread to my remote machine.I'm guessing that the problem lies with the new thread generation before the activity fully loads not sure.LogCat is fairly cryptic here. It does say something about thread attach failed, then shows an uncaught handler exception that has "Caused by: java.lang.NullPointerException" within it.Again, if I put this call to the method inside a button click, I"m in business, if it's in the onCreate() it fails. Is there some way inside an activity (presuming that my assumption is correct that it needs to fully load before spawning a new thread) to call the StartSocketServer() after it's loaded: ala body.onLoad() in html?
I have a .Net Web Service which returns a single integer value. When i call upon it from my application, no value is returned. Nothing at all really happens. I set up breakpoints and watched it's progress and it seems the problem is coming from when i get to this line:androidHttpTransport.call(SOAP_ACTION, envelope);
I have a hunch that my URL string is the problem. I've tried replacing the "localhost" in my URL string with my local and network ip with no luck. Whenever i replace the localhost with the ip in my browser i get Server Cannot Access or Unable to Connect pages. Does anyone know a solution to this problem?
A service is setup by an activity with startService(service_intent). This service is meant to run 24 hours a day. After some amount of time, 5 or 6 hours sometimes but its not predictable, the service is killed.In the database log, the destroyed message does not show up and the notification #1 is not cancelled. Android makes no attempt to restart the service. The database log will show the startup of the replacement service if I trigger it by visiting the activity. What can I do to keep this service running or at least get it restarted by android automatically?

View 2 Replies View RelatedIf an application begins a Service via bindService or startService, will this Service object ever run from a process different from that of the application? I ask because many Android example projects begin a service and communicate to them using IPC which seems wholly unnecessary considering that, according to the Android Service documentation, "... services, like other application objects, run in the main thread of their hosting process." IPC, AIDL, and the IBinder interface only seem useful if connecting to a Service started by an application other than your own. Is this a correct or fair understanding?

Is there a way that a Service can report back to the calling activity when the Service has reached a particular stage of processing? Consider a music player activity that initiates the actual music playing in the background as an Android Service. I want to detect and inform the Activity when the Service has reached the Mediaplayer's onPrepared. Is there a way that the Service can tell the calling Activity when the MediaPlayer's onPrepared is called, to let the Activity know that the audio is prepared and ready to play?I am basically looking to see if there is work around, rather than having a thread in the activity, pinging constantly to check if the Service has reached onPrepared.
View 2 Replies View RelatedI'm designing an android app which will need to do the following steps:
1. User pushes a button or otherwise indicates to "sync data".
2. Sync process will use rest web services to move data to and from the server.
3. The data will be stored locally in a sqlite database.
4. The sync process should provide status updates/messages to the UI
5. The user should not be allowed to wander off to other parts of the application and do more work during the sync process.
The first time the sync process runs, it may take 10-20 minutes. After the initial sync, less data will be transferred and stored and I expect the process to take 1-2 minutes or less. I've been doing a lot of reading about android's AsychTask and various examples of using a Service. But I don't fully understand the design considerations and trade-offs of choosing one design over the other. I currently have my demo project stubbed out using an AsychTask. After watching (most of) Developing Android REST client applications:
http://code.google.com/events/io/2010/sessions/developing-RESTful-and...
I'm left confused the design patterns described here feel overly complex, perhaps because I just "don't get it" yet.
I am attempting to signal my widget such that it receives my new Intent from my service
The code I am using to send from the service is as follows:
CODE:...........................
I have a Service/AlarmManager set to go off ever hour; as seen at: http://github.com/commonsguy/cw-advandroid/tree/master/SystemServices...
The Alarm triggers a Socket connection to communicate with a Web Server. I'm logging the interaction to a file so I can see it later. When I leave the phone on my desk for a day, it seems that more often than not I get a "Network unreachable" error when trying to do any networking.
I believe it is related to how deeply the phone goes into sleep. Is there a special kind of lock I have to hold, or some command required to prep the wireless radio so that it can be ready to access the Internet?
I'm having an issue with inter-process communication with a Service and Notifications
The structure of my application is as follow: - ListActivity (TunnelDroid), once the user presses a listitem it will start a Service. The ListActivity is binded to the service for intra-process communication
- Service (TunnelManagerService): running in the background. This service will add a (permanent) Notification in the statusbar. Using a Handler I sometimes need to communicate with the ListActivity (to show GUI Dialogs)
- Notification: Once this notification is clicked it should open the ListActivity.
To add the action when the user touches the notification I use the following code: notificationIntent.setClassName("net.sourceforge.tunneldroid","net.sourceforge.tunneldroid.TunnelDroid"); Then I use the intent to create the notification.
Unfortunately a new Intent is opened. When I press the back button the original ListActivity is shown. So I have two instances of my same class/list.
How could I make sure the original ListActivity is opened when the user touches the Notification?
It's OK for me if the original ListActivity was previously destroyed, but I cannot have two instances. The problem is that the Handler in the Service has a reference to the ListActivity (PARENT_ACTIVITY), so if another instance is created I have invalid references. I could overwrite the PARENT_ACTIVITY, but then when the user presses the back button I have an instance with no correct link to my Service resulting in a crash/nullpointer.
The complete source can be found here: http://tunneldroid.svn.sourceforge.net/viewvc/tunneldroid/tunneldroid. Attached you can find a drawing of (most of the) inter-process communication. Could someone point me in the right direction?
