Android :: Bind To System Service
Mar 11, 2010
is it possible somehow to bind to private system services? What I want to do is listen to the activitymanagerservice and be notified when other activites are started. I tried implementing the IActivityController.aidl from the Sourcecode. It has methods like activityStarting and activityResuming but this didn't really work. (I used the idea from here: http://blog.codetastrophe.com/2008/12/accessing-hidden-system-service... , problem is there is no proper private field one could use at least c.getDeclaredFields() doesn't return anything useful from the activity manager)
Any ideas how I can get notified of things going on in the Activity Manager without having to do a getRunningTasks all the time? Because this is the only workaround I came up with but it slows down the phone.

i get an error message like 09-30 20:08:24.733: ERROR/AndroidRuntime(949): Caused by: android.content.ReceiverCallNotAllowedException: IntentReceiver components are not allowed to bind to services 09-30 20:08:24.733: ERROR/AndroidRuntime(949): at android.app.ReceiverRestrictedContext.bindService (ApplicationContext.java:136) so i guess you can't bind to a service in an AppWidgetProvider - although you can start the service just fine?

I'm new to Android development and am working on a small test project. I have a service, which communicates with an SQLite3 database, and two activities. A main activity which fetches database information via the service and displays it and a second activity which allows me to add data to the database via the service.
Currently, I have a singleton class which implements the ServiceConnection interface and I'm binding this to the service in the the main activity using the bindService function. Because it's a singleton, I can then use this service connection in both the main activity and second activity to work with the database and it all seems to work quite well.
However, I'm all the time aware that the service connection is bound to the main activity and I'm wondering if this is the wrong/bad way to do it? Would I be best off having two service connections, one in each activity, and binding each to the service?

I have coded this service, that computes stuff and i want other applications to be able to bind this service, i.e. i want to enable other programmers to communicate with this service. problem is, this has to work without these other programmers to get access to the source code. just the (installed) apk with the remote service is given (and of course a detailed description of the service' interface)...problem is, eclipse keeps braggin' about that the packages of the service are not available in source code...

I'm developing an automatic vulnerability scanner/exploiter for android. I'm adding the cool feature of using the metasploit framework from our android phones.
I can start the MsfRpcd ( the metasploit daemon ) from a su shell an make it bind to the 127.0.0.1 address.
I can connect to the server using busybox netcat ( no Java though here ).
I can't connect to 127.0.0.1 from the android app! i got ECONNREFUSED.
After a bit of google i understood that JavaVM have a separate network and it filter out my connection to localhost/127.0.0.1.
how can i connect to a service bind to 127.0.0.1 on my phone from an android app?
I gave a quick look at iptables -L output, maybe i can make some hack there, but probably i will break the JavaVM network.
Binding on wifi ip is not an answer.

A new question about android and services. Currently I'm developing a App that should send images to a server. It should also be possible to send more images parallel. I made a service that creates for every image a new image. The activity can bind to that service and gather information about the progress. I want to show the current status for every image in a notification (and when the user clicks a notification, an activity with the progress for that image should be shown). But I get several problems with that approach. There are errors with binding, the notification pending event starts the activity completely new, so I lose information about currently sending images and so on. How I could design in a appropriate way.

From what I can tell -- if you return START_NOT_STICKY from Service.onStartCommand(...), the system should not restart a service if it crashes. However, I'm not seeing that behavior -- any ideas on what could be restarting the service?

I have issue with displaying AlertDialog from Service. I am able to display custom layout window using Toast or using WindowManager(TYPE_SYSTEM_ALERT or TYPE_SYSTEM_OVERLAY). But, I do not want to use custom layout, I prefer to use nice AlertDialog GUI directly.
Scenario:
Running Service. No active Activity present. On some external event, Service sends Notification
When user press Notification, Service is informed via PendingIntent and AlertDialog should be displayed (created with AlertDialog.Builder(this))
Error: ERROR/AndroidRuntime(1063): Caused by: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application. Searching for the answer lead me to impression that I am trying something that is currently not possible (Android 2.2). Or maybe it is.

I just would like to ask if anyone have encountered this strange behavior with other phone models or specifically HTC Tattoo wherein I have this service running for almost 5 hrs then after sometime the system kills the service. The phone does not restart actually nor any other 3rd party applicaton running in the background. Its only the service I have is running. I was wondering what were the causes that would force to close my service. Another strange thing is that before the service was closed I still can see all the logs in the logcat but after I saw that the service was closed I don't see any log information already seems like the phone was totally disconnected from my eclipse.

I have noticed that if my background service crashes the system will automatically restart the service after 5 seconds. This is great, but I have noticed that only the onCreate method gets called and not the onStart method. Does this mean the service is properly restarted or do I need to do something special in the onCreate method to make sure it is? I did have my initialisation logic in the onCreate method and my starting service logic in the onStart method but it looks like it will all have to be in the onCreate method.

If so How to do I go about it?

For G1, binding account is easy, an app-wizard will helped to do this matter when you first turns it on. But how to make this on non-G1? It seems that the related api is NOT exposed.

Two activities here, A and B. A is main, B is PreferenceActivity with two EditTextPreference.
I want to be able to access the preferences generated by B from activity A, and for that I need of course (I guess) getSharedPreferences on A. But in order to do that I need to supply the preference file for the activity that generated it. This is tedious (long names), erratic at best (depends on the activity that generated it), and finally it's a mess, because it's much better to keep everything under one xml file, with a name that is well known to all my activities. And besides, if I have 100 activities, how would I keep track of preference files anyway...
So the point is: how do I "bind" an EditTextPreference in a way that the changes are made to a given preference file, not the one automatically generated by Android?

What I need is to perform some network operations in background inside a service. I want them to run in a service because, as pointed out in the "developing rest client application" talk from google io, I don't want to loose the result if the activity is brought in background. What sounds quite obvious is to use an Intent Service, and get the result as a broadcast. In this way I am sure the service will die and no consume any other resources when its done, but I need to convert the actions I want to perform to intents and back. Well, I was now wondering if it makes sense to bind to the service instead, at least for getting the result. And a more general question: is the bind mechanism suitable for one shot services, or it just make sense for persistent services? What happens if I call the startService method but the service is already active? Will it start another service, or will it call the onStartCommand of the same service? I am asking this because if I use "regular" non sticky service, it could happen that I need it to perform some action and I don't know if it is already active (and I don't want to have a queue of action waiting for onServiceConnected to be called.

I get my Models in a nice object-oriented form. In order to bind them to my List, I have to use the listAdapter. Can I only fill this listAdapter with stupid ArrayLists? Because that means, I have to iterate over my ModelCollection and pull all the data out of my Models again. So, I detach my data from the models and I cant easily refresh the data in my listView, if something chances in the modelCollection (like becoming bigger through new Items / pagination). Does a more intelligent way exist, than I use right now? Can I bind my ModelCollection more driectly to the listView?
ModelCollection modelCollection = ModelCategory.findAll();
/*
* Prepare Data for Adapter
*/
ArrayList<String> itemTitles = new ArrayList<String>();
// Iterate over my ModelCollection and pull all the Data from each Model
for (int i = 0; i < modelCollection.items.size(); i++) {....................
