Android :: Service Call Backs To Activity?
Jan 8, 2010
I have a back ground service running.I have a client which interacts with service.
When the client requests for some operation, the service performs it and it should send the result back to the activity(client).
I know how to invoke the service methods in activity and using call backs we can achive wat I wan to do. But I am not able to understa the call back mechanism and code example provided in Api demos(remoteservice).

I have an Activity (A) and a Service (S) which gets started by A like this:
Intent i = new Intent();
i.putExtra("updateInterval", 10);
i.setClassName("com.blah", "com.blah.S");
startService(i);
A have a function like this one in A: public void someInfoArrived(Info i) Now I want to call A.someInfoArrived(i) from within S. Intent.putExtra has no version where I could pass an Object reference etc.

Whenever the memory needs to be reclaimed, the process is being killed by Activity Manager Service in killPidsForProcess. I have a back button in my activity window on right corner of the title bar.
I want to kill the activity completely on clicking the close button. Can I reuse the same function and will it have any major effect? Please help me out in this.

Has anyone found a Android backup program that backs up the applications and everything on your phone to your PC? So that you can restore it back from your PC without involving a 3rd party website ?

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.

Just read this from another thread thought root users would like to know you can save your screen setups now. I figured this will save me about 30 minutes each time I change a rom. I tried it out and it worked great. With all the ROM's I like to try this will make me change from L.P.

I am requesting information from a web service in my android app. The web service returns a list of items, each item having a base64 image and some info
First method: simply access the web service and get the result. This means freeze of UI until data is downloaded. Not a good solution
Second method: put the data download in a thread, and display a progress bar with a message.
private void StartGettingData()
{
viewInfo = new Runnable(){
public void run() {
getData(); //from the web service.......................

I have a Service which is typically bound to, but sometimes needs to go into a mode where it should be active even if nobody is bound to it. Therefore, startService() must be called so it can be explicitly started & stopped. In my case, when exactly this should happen is best determined by the service itself, depending on its state (after being bound to). Can the Service (at the appropriate time) just call startService() from it's own Context?

(I'm new to OOP)

In Virgil Dobjanschi's talk, "Developing Android REST client applications" (link here), he said a few things that took me by surprise. Including:
Don't run http queries in threads spawned by your activities. Instead, communicate with a service to do them, and store the information in a ContentProvider.
Use a ContentObserver to be notified of changes.
Always perform long running tasks in a Service, never in your Activity.
Stop your Service when you're done with it.
I understand that he was talking about a REST API, but I'm trying to make it fit with some other ideas I've had for apps. One of APIs I've been using uses long-polling for their chat interface. There is a loop http queries, most of which will time out. This means that, as long as the app hasn't been killed by the OS, or the user hasn't specifically turned off the chat feature, I'll never be done with the Service, and it will stay open forever. This seems less than optimal.
Long question short:
For a chat application that uses long polling to simulate push and immediate response, is it still best practice to use a Service to perform the HTTP queries, and store the information in a ContentProvider?

Our application will expose a Service that can be called by Activities in other people's applications.In many cases, the parent applications calling Activity may be paused before our Service completes. I am looking for the best way for a Service to communicate back to the calling Activity that may have been paused.These are the known options:
(1) Require calling Activities to have a registerReceiver() with a custom action and broadcast to that from our Service. The only way to secure this registerReceiver() is with a signature-based permission.As our Service communicates with any number of unknown 3rd party apps,we can't sign our Service's parent app with all these unknown certificates. These apps would therefore be exposing an unsecured registerReceiver() on their Activity. Would ideally like to avoid requiring this.
(2) Create a PendingIntent to send results back to the activity and give it to our Service. Our Service would send data to calling Activity's onActivityResult(). Each time the result is delivered, the calling Activity will go through onPause() and onResume() but this should be OK.
(3) The calling Activities could create a Handler. The Activity would then create a Messenger pointing to that Handler and send it to our service. Our Service can then use the Messenger to deliver our message back to the calling Activity.

My application has a background process which continuously waits on a socket for receiving messages and it should be started only once and at the time of application starting.Thus i want to do that background job in a service.
The service should not be started from the activity ,it should be started at the application starting.
How can i define the service,which will be started at the time of application starting?
If at all the service is started from activity.The activity can be destroyed and restarted.when this happens the service also be restarted .
