Android :: Bind Remote Service - That Installed On Device
Sep 5, 2010
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...

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'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.

I'm confused about whether I need to run my service in a separate process. What are the advantages / disadvantages of each?For reference I'm trying to create an App that uses a service to play [streaming] audio in the background. So which one is better for my use case?

I'm developing a GPS tracking software on android. I need IPC to control the service from different activities. So I decide to develop a remote service with AIDL.This wasn't a big problem but now it's always running into the methods of the interface and not into those of my service class. Maybe someone could help me?If i now try to call a method from an activity for example start(trackId) nothing happens. The binding is OK. When debugging it always runs into the startTracking() in the generated ITrackingServiceRemote.java file and not into my TrackingService class. Where is the problem? I can't find anything wrong.

I am studying RemoteService example in Android's APISample. In the manifest file, it declares the service like this: My question is how can I specify the service to be 'auto-start', i.e. it gets start whenever the phone start?
<service android:name=".app.RemoteService" android:process=":remote" >
<intent-filter>
<!-- These are the interfaces supported by the service, which
you can bind to. -->
<action
android:name="com.example.android.apis.app.IRemoteService" />

I have implemented a RemoteService which will increment a countere ( just for testing purposes ). Therefore I have a Task class which implements Runnable and the method run() where a infinite while loop increments the variable.
From the client side, I start the RemoteService with startService and then i bind to the service. When I close the activity, the service is still running. Now i want to rebind to the service.
How do I know if the service has already been started (therefore i would only need to bind to the service again) or not (then I would need to call startService() first and then bind to the service)?
What would happen, if I call startService() if the service is already running? Does the OS start a second service, or will it affect the service which is already running?

My initial activity is basically a splash screen while preforming initialization and login in to network server. To save memory I want to finish() the splash activity once it starts the main menu activity. I still want the remote service to operate. Testing shows it does. But am I going to get into trouble doing this? I know I can restart the remote from the main menu activity but I am trying to save overhead by not starting it twice. The remote service is required by the splash activity.

I defined a remote service over a AIDL file. Now i want to access this service in a different application. But how can I do that? The AIDL file is not accessible in my second application, and if i just copy the AIDL file, then the service can't be found.

I'm hoping to do some audio processing in a remote service (service I've spawned onto its own thread); this will basically occur in a while (1) loop so constant processing. Occasionally I want to provide some information back to the activity that is bound to the service; I'm doing this by sending a broadcast from the service, that is received by a broadcast receiver on the activity, which then uses the activity's service connection to call into the service and get the information needed; at this point the broadcast receiver makes an alert dialog presenting the information to the user.If I stay in my while(1) loop after raising the broadcast, the action in the broadcast receiver never seems to occur.This is confusing to me since the activity and service are in separate threads.If I end the loop after raising the broadcast, the desired behavior on the activity side occurs, but of course this isn't acceptable since I need to be doing constant processing.

Since yesterday I got an idea running around my mind but I donīt know first if it would work, and then how "hack" it would be.
People who develop audio processing/recording/playback apps for Android know how hard it is to maintain GC away from our critical paths: playing and recording audio. Processing must be as optimized as possible not only to save battery and use less CPU, but also not to create new objects/allocate new memory spaces ... this all to avoid GC at all cost. Well, we have knowledge and this we can handle (mostly). But what about all the other processing that happens from and for user interaction? Media players display images, some apps display ads, ... and sometimes we have to avoid releasing features to the users just to maintain our critical paths free from GC.
Yesterday I stumbled upon an article about remote services and this led me to a doubt: if they can run as a different process, would a GC call from my activity impact the performance of my remote service? I really donīt know how GC works on the Dalvik so this may be a dumb question. If so, I apologize.

Is there a way to step through code in a remote service? What I do now is install the service, then run the app that starts it and use trace output. Is there a way to perhaps automatically start the service upon installation, and have it stop at break points? Or is there another method?

I like to do some long running initializing work in a remote service, and during that, a progress dialog shall be shown. So basicly, I invoke ProgressDialog.show, run a oneway method of the service with a callback to be invoked when it's finished, and in the callback dismiss the dialog. I expected the service method to work in it's own process while the activity shows the progress dialog. But what happens instead (according to debugger and logs) is: ProgressDialog.show and service method invocation return immediately, then the service method is processed, and finally the progress dialog is shown for a few milliseconds right before it's dismissed. Even a "not responding" error might occur during that. If I invoke the service method in an own thread, which (as it's to be expected) is finished long before the service method is done, everything works fine. But I don't get why this is necessary. Why does a remote service method block the Activity thread? This even happens if the service method only does a Handler.post and returns immediately.
Simplyfied code overview: Activity: public void onStart() { startService(...); bindService(...);}

I didn't find a sufficient answer to my problem in any posts, if there already is one, please excuse and point me to it, thanks. I made 2 projects. project 1 hast an activity that binds to a service from project 2 on a button click (all just for testing).
How can I make project 1 know (import) my TestInterface (from TestInterface.aidl out of project 2) for usage in: "TestInterface mService = (TestInterface) TestInterface.Stub.asInterface(service);"
without adding project 2 to the build path, because if I'd have an installed service without the project code, I couldn't do it this way, too...?? I read in one thread that TestInterface.aidl should just be added to project 1, too, but if I do this, in DDMS enforceInterface() complains and seems to just see/use the interface from project 1 and it doesn't work.

I've been researching how to best implement a service which performs a network transaction and returns data to the caller.
Clearly, this needs to happen on its own thread which means some form of async response. I can see at least three ways of doing this--some more complex than others. In the descriptions below, C is the caller, S is the service.
1) C wraps a Handler in a Messenger object, adds this to an Intent. C then calls startService with this intent. S extends IntentService which runs the Intents received in a worker thread. S then sends a message to C via the Messenger. This has the benefit of not requiring any of the async binding process or making an IDL interface that needs to be compiled into C. This seems to be the closes to a Handler-based response mechanism of Local Services.
2) C binds to S and then uses AsyncTask<> to make a blocking call to S. S performs the network transaction and returns the data in the return value or an out parameter. This requires the async binding process, but does not require a callback function since the inter- thread communications is handled by AsyncTask<> and the worker thread is in C's context.
3) Make the function called in S be completely asynchronous. S defines two interfaces: IMyService and IMyServiceCallback. S implements IMyService.Stub. C implements IMyServiceCallback.Stub. C binds to S then calls S via IMyService, passing its IMyServiceCallback binder. S spins up a worker thread and returns immediately. S then calls the callback when it has completed the network transaction.
I am asking for advice on which methods are most appropriate. I do not need the the service running constantly, only when the web transaction is required. C does not use S all the time--definitely don't want to bind during C's onCreate. However, I would like the time from when C determines it needs to use S to getting the results back to be as quick as possible (i.e. adding minimal latency to the already latent network access).
Is there any preference to having the worker thread in C or in S? Are there any significant problems with option 1?
