Android :: How To Start A Remote Service In Android That Is Implemented In Another App - Different Package
Jun 19, 2010
i'm a bit stuck with remote services in android. thing is i implemented a remote service in package "a.b.c" and i want other applications to be able to access this service. i got rid of the whole crappy aidl-stuff and designed the "interface" of the service to work via broadcasted intents. works fine so far...
problem is: how do i get a different application (different package, different project, maybe even a different developer, ...) to start/stop the service?
CODE:..........
This will crash my app immediately on startup. what did i do wrong? how will i get this to work?
once it's running, commands and data will be passed via broadcasts. so that should be no real problem...

I have two apps, one runs in namespace com.gtosoft.voyager and the other is com.gtosoft.dash. From com.gtosoft.dash I would like to start up the service which is defined in com.gtosoft.voyager...
I think I need an intent, but what arg(s) would I pass to the intent before kicking it off with startService()?
If they were in the same package I could just use

I have a service class my.app.MyService that I'm attempting to launch from my.app.MyActivity as follows:
Intent svc = new Intent( this, MyService.class );
The manifest contains the entries:
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_SERVICE" />
<service android:name =".MyService" />
LogCat gives the message:
"Unable to start service Intent { comp={"my.app/ my.app.MyService" } } : not found"
Could someone kindly let me know what I am missing?

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?

My application has 2 packages because one is shared with my other applications. I want to start an activity of the shared package.
I tried the following: Intent intent = new Intent(); intent.setClassName(shardedPackageName,sharedActivityName); startActivity(intent);
It throws an ActivityNotFoundException and suggests that the activity might not be in the manifest. But how do I list an acitivity from another package in the manifest?

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 know how to update my own programs, and I know how to open programs using the a predefined Uri (for sms or email for example)
I need to know how I can create an Intent to open MyTracks or any other application that I don't know what intents they listen to.
I got this info from DDMS, but I havn't been succesful in turning this to an Intent I can use. This is taken from when opening MyTracks manually.

I am trying to access a service in other package, but not able to get the binder.code...
In the ExampleActivity i am accessing the service by doing
but onServiceConnected( ) is not getting called, so i am not able to get the binder. But process everything is going fine , in the Eclipse console i am able
I tried with serComponent( ) & serClassName( ) as well, but for both the cases onServiceConnected( ) is not getting called. I googled and used the hint for listening boot completed and user present intents and starting the service in the broadcast receiver.
how can i access the service of other package (process).

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 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 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.
2. issue:...............
