Android : How Can I Call Service Methods From BroadcastReceiver?
Dec 7, 2009
I made two applications. One for an activity receiving user input, the other for a background service. In the service package, I create two files (startSensorBroadReceiver.java, remoteService.java). StartSensorBroadReceiver will receiver an intent from activity application and call method inside of the service. There is no erron in the codes but I can not excute what is want. I meet a message like this "The application ServiceExample has stopped unexpectedly. Please try again." could you let me know. what is wrong? and how I can call service methods from broadcastReceiver?

Hi, custom classes which are part of a framework, so nothing graphical. One of those (singleton) classes is a Logging class which send logs to my server. I noticed that even though I can call the classes methods in my service it actually won't be logging anything... In my specific example it's osmething like : Logger.getInstance().log("Whatever I want to Log"); Obviously the getInstance is a static method so it can be accessed from anywhere within my project right away.. I was wondering though why this method for example isn't getting called ? Also how do I debug a Service ? Btw I am using of IPC from one of my Activities which gets bound to the service and can start/stop the music for example...

I was wondering if it's possible to call specific methods defined within the AsynTask class from another class and/or service ?
In my specific case I have a Service playing some sounds, but the sound is selected from a List with available sounds...
When a sounds is selected it is downloaded from my home server, this takes some time (not much, let's say around the 3-4 seconds, the sounds/effects aren't big in size)...
So my problem at the moment is that I have a service to play those sounds, and when I select one I wanted to show a progressdialog... The way (if I understood correctly) is to use an AsyncTask, but the only thing the AsyncTask will do is telling my Service to play a specific sound from my server... So there is no "callback" from the service to the Asynctask...
How can I call a running AsyncTask, which sits in another class, and tell him all work is done and thus he can stop showing the ProgressDialog ? Or am I over-engineering it and there are other ways ?

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.

Can I Receive a Broadcast from a Service? It seem I have to extend BroadcastReceiver to receive broadcasts but I'm already extending Service and I can't extend 2 classes. Do I set up an additional Activity to receive broadcasts and then just pass stuff to the already running Service. And if so, how to I pass additional info to an existing Service? Is there a better way?

I have seen several examples on how to implement a BroadCastReceiver, but how should I implement a Service who has to react on some pending Intent (for example incoming phone call)...Actually I was wondering about the same "prbolem" but in an Activity..You obviously have a class which extends a Service 9or an Activity) so it cannot also extend BroadCastReceiver...It looks like we cannot make "platform-awar" services and/or Activties ?

My application has the following components: 2 Activities A Service and a BroadcastReceiver
Whenever the user updates the system time, my broadcast receiver receives the Intent.ACTION_TIME_CHANGED. Now when this happens I want to reschedule a Handler in my Service. How do I bind to a Service within my BroadcastReceiver?

While developing an alarm based application, i have stuck in a scenario.
When my alarm is fired, i can receive the event in BroadCastReceiver::onReceive().
Within this function, i want to notify/call a function, which is located on MainActivity.
How to achieve the same?

So I'm writing an Android app which uses a large c++ library. I have everything working so that the java app can call the c++ delegation methods, but I'm finding myself wishing I could log messages from c++ to the Android log. This is easy from java, but I'm at a loss as to how to call a java method from c++. My searches found methods for opening a jvm from c++, which is not at all what I want to do. Ideally, I'd like to pass a log method pointer to c++, which could then be used whenever I wanted. Of course, java doesn't support method pointers.

I am curious whether the AIDL only serves for inter-process communication between several Android apps on the same device, or AIDL provides much wider functionality. Let's say I have a Java application running on some server, is it possible to remotely call methods on that server through AIDL from an Android phone?If yes, do I need some extra libraries on the server-side Java application?

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 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.

I'm getting a Java Socket Exception "Operation timed out" when trying to call a .NET web service method. I've followed the many examples out there on the web to get my android to call a .net web service.
I'm running the web service using VS2010 in debug mode. The web method I'm calling is very simple -> "string GetVersion()"
I've read some posts that eclipse needs to be configured to access the internet by modifying the Proxy preferences "Preferences -> General -> Network Connections" from the Window menu item. I haven't been able to figure out exactly what I need to configure in the Proxy to get things to work if that is the problem.
I've also tried to access the .net web service root page (service.asmx) from my android with no success. I can access the asmx page with no problems using IE on the local machine. I've turned off the firewall and that didn't solve anything either. This is the first time I've tried to access a web service from a remote computer when it was running using VS2010 in debug mode.
I don't know if I have a configuration issue on the eclipse side or on the VS2010 side.
I'm also running Windows 7 Home Premium.
Below is a code snippet...

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'm rather new to Android, so please bear with me. I'm developing an application running a service in the background. The service is ONLY supposed to run when requested somewhere in the UI. The service must be able to be stopped through the UI as well. At the same time, while running, the service must be able to pick up intents such as "intent.action.DATA_SMS_RECEIVED" and "intent.action.NEW_OUTGOING_CALL".
