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.

Android :: Service Unable To Call Java Class Methods / Way To Fix?

Jun 22, 2010

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...

Android :: Call AsyncTask Methods From Another Class - Service - Callbacks?

Jun 1, 2010

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 ?

Android :: Android Remote Service Doesn't Call Service Methods

May 28, 2010

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.

Android :: How To Call Java Methods From C++ In JNI?

Oct 10, 2010

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.

Android :: Remotely Call Methods Through AIDL

Jul 21, 2010

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?

Android :: Using Activity Lifecycle Methods / What's Best Strategy For Binding?

Sep 15, 2010

I'm binding to a local Service (that is, not using IPC and AIDL) from several activities. I want to ensure that I'm not holding references to this service from activities that the user isn't using. My options are: 1.) to bind to the service in onCreate() and unbind in onDestroy(). 2.) bind in onStart() and unbind in onStop(). 3.) bind in onResume() and unbind in `onPause(). Or some combination of these. Which is the best-practice way of binding and unbinding to a local service? Do I not need to be concerned with holding local connections from stopped activities? Additionally, once bound to this particular service I am retrieving a Cursor which is attached to my ListActivity via a CursorAdapter. The data retrieved by the Cursor may have changed while the Activity was out of view so I want to requery it when the Activity is shown again. If I bind in onCreate() I can requery in onRestart(). If I bind in onResume() each time the data will be fresh because I'll query it in the Service's connected callback.

Android :: Accessing Activity Methods Inside Click Listener

Aug 25, 2009

I have a click listener:
private OnClickListener onMyListener = new OnClickListener() {
public void onClick(View v) {
myMethod();
} };

And my Method:
private String myMethod() {
TextView tv = (TextView) findViewById(R.id.TextView1);
return (String) tv.getText();
}

When it calls this method, at tv.getText() it breaks in the debugger.
With this in the stack --
ViewRoot.handleMessage(Message) line: 1571
ViewRoot(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 123
ActivityThread.main(String[]) line: 3948

Android :: How To Have Shared Menu In Each (List) Activity Without Re-writing The Overridden Methods

Jan 5, 2010

I know that Android provides some useful methods to be overridden in order to define a menu:

CODE:..............................

I would like to have this menu shared by each Activity and ListActivity of my Android application. This is for having a standard menu in each (List) Activity that lets the user jump to every part of the application within a click.

Right now, the easiest way to achieve this is to copy-and-paste both methods in every (List) Activity of the application. I don't like this redundancy of code written.

Is sub-classing a reasonable choice? I've already seen that sub-classing one of my ListActivity does not work very well (threads that retrieve objects from a database are giving problems). Are there other ways to share a menu though Activities?

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.

Android : How Can A Service Call StartService On Itself?

Jul 19, 2010

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?
