I have a service, that requests another class, which launches an AsyncTask
Service->Weather Class->Execute Method->Asynctask->Execute
this is launched in the service by
new Weather(this).execute(); // the execute is a method of the class, not of the AsyncTask
how do I detect in Service that the AsyncTask finished so I can call stopSelf?

I have an activity which starts a service. In the service there is a network lookup in an AsyncTask. Results from the lookup are saved to a database.
The activity queries to database and shows the newest entries. But at the very first run the database is empty, so there is nothing to show. In this case I would like to show a progress dialog to the user while the network lookup is taking place. I would like to dismiss the progress dialog when the first lookup is finished.
Is there a way to access the progress dialog created in the activity from the service? Or how to do it?
I am programming a game. I have a service for the background-music. When I press the home-button and leave my activities, the service still runs in background. How can I stop the service, when there is no more visible activity in my program and restart it, when the user goes back to my game (some activity of it)?

Once it has finished doing it's work I would like the service to stopSelf(), how can I get the service to determine when it is no longer needed (ie, there are no more Threads executing) so that it can shut itself down automatically?
I am stage managing a show and have all of the sound cues on my Droid 4
The only problem is that I am using 'My Music' and when cue finishes (say a gunshot) the next begins (say a fog horn). This is very problematic

I keep my phone near my head on my bed, since I use it as an alarm clock. Unfortunately the Vibrant is vibrating at the end of the charge cycle, which is distracting when I'm trying to fall asleep!
I can't find a setting to turn this off. I have haptic feedback turned off. I keep the phone in vibrate mode (ringer volume = vibrate).
I have an AsyncTask object which starts executing when the activity is created and does stuff in the background (downloads upto 100 images). Everything works fine but there is this peculiar behavior which i'm not able to understand.For eg: when the android screen's orientation changes then the activity is destroyed and created again. So I override the onRetainNonConfigurationInstance() method and save all the downloaded data executed in the AsyncTask. My purpose of doing this is to not have AsyncTask run each time activity is destroyed-created during orientation changes, but as i can see in my logs the previous AsynTask is still executing. (The data is saved correctly though)I even tried to cancel the AsynTask in the onDestroy() method of the activity but the logs still show AsynTask as running.This is really strange behavior and would really be thankful if someone can tell me the correct procedure to stop/cancel the AsynTask.

On the official documentations it is stated that Note that services, like other application objects, run in the main thread of their hosting process and AsyncTask only works if it is executed in the UIThread.
So is it possible to use AsyncTask in a Service class? code...
I have a Service that creates AsyncTasks for downloading files. In activities, we create Runnables or Threads that we pass to Activity.runOnUiThread(). I can't access that method from a service, so how do I use AsyncTask correctly, (do heavy work without blocking the UI Thread)?

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 trying to figure out the correct way to create an AsyncTask to retrieve some data from the internet and then to take that data and bundle it up in an Intent and pass it to a new activity(A list display). So in the first activity I just have an EditText and Button. In the event of an OnClick the task should be called and when it is finished the data should be bundled inside an Intent and passed to the next Activity. The problem is when I take the results from onPostExecute and set them to an instance variable of the main activity, that instance variable is still null when the task is complete. Here is the barebones version of the code:
CODE:...........
When I debug the application I see onPostExecute does contain a valid PlacesList full of results, so why is the instance variable places set to null after the task is executed? I am going about "returning data" from an AsyncTask incorrectly?
Okay when user presses log out button what's supposed to happen is:
Code:
stopService(myIntent);
unbindService(mConnection);
mIsBound = false;
I need to shut down the service on background.Except the service restarts itself over and over again! Even if I kill the program from task manager the service restarts itself. Other programs aren't using the service. when I uninstalled the program the foreground program information popped up indicating it was STILL there(albeit this I solved by rebooting phone).
When user says he's finished with the program 'least he can expect is for the program to stay down rather than keep eating battery by acquiring GPS signal and sending them to server. The program is not intended to be "once you log in you need to Uninstall me and reboot phone to get rid of me!" type of program!
I start a service in an activity then I want the service to stop itself after awhile.
I called stopSelf() in the service but it doesn't work.

I have a service receiving and sending data to a server in separate threads each. The service lifecycle methods look like this:..................

View 2 Replies View RelatedIs there a way I can test if there are any other activities in my app still alive? I am looking to stop a service in an onDestroy method, but only want to do this if there are no other activities from my app still alive on the stack.
I have the call stop the service in the main activity's onDestroy() method. This works perfect EXCEPT that if a user launches my app, then launches a few activities in my app, then hits the home screen and RELAUNCHES my app, they will subvert my order and the main activity will now be above other activities of my app. From this state, if they hit the back button and 'back out' of my home screen they will trigger the onDestroy() method and kill the service even though there are other activities open on the stack. I want to avoid this by stopping the service ONLY if I am sure there are no other activities of mine open on the stack.

View 1 Replies View RelatedI have a service which runs in the background when the user starts using my app. I am using it to do some posts to our server. I always close my service by calling stopSelf as soon as the posts have been made or failed.
But I recently observed two times that my service did not stop. I saw that in the running services in settings on my device that it has been sitting there for over a few hours.
So I was trying to see if I can alternatively set a timer using which I can force the service to stop after a few minutes no matter what.
I am trying to call my service class's stopService() method from my activity. But I don't know how to access stopservice method from my activity class. I have the below code but its not working. This is HomeScreen class:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
enablecheck = (CheckBox)findViewById(R.id.enablecheck);
enablecheck.setOnCheckedChangeListener(new OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(enablecheck.isChecked()){
startService(new Intent(HomeScreen.this, AutoService.class));
} else {
stopService(new Intent(HomeScreen.this, AutoService.class));
} } });
}
This is Service Class:
public class AutoService extends Service {
private static final String TAG = "AutoService";
private Timer timer;
private TimerTask task;
@Override
public IBinder onBind(Intent intent) {
return null;
} @Override
public void onCreate() {
Toast.makeText(this, "Auto Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
int delay = 5000; // delay for 5 sec.
int period = 5000; // repeat every sec.
timer = new Timer();
timer.scheduleAtFixedRate(task = new TimerTask(){
public void run() {
System.out.println("done");
} }, delay, period);
}
@Override
public boolean stopService(Intent name) {
// TODO Auto-generated method stub
timer.cancel();
task.cancel();
return super.stopService(name);
} }
I had the program I wrote a service, and in service has written a timer, change the timer for one minute cycle time, but why the program in the phone standby (screen lock) were time, I have the timer will be stop running, when I click the menu, get back to normal mode when the timer will automatically have to run? What is the reason, how to solve?
View 2 Replies View RelatedI have created a threaded service the following way. code...
After I close the application the phone works really slow and I guess it is due to thread termination failure.
Does anyone know what is the best way to terminate all threads before terminating the application?
I start service by using:
private ServiceConnection _serviceConnection = new ServiceConnection() {...}
bindService(new Intent(this, MainService.class), _serviceConnection, Context.BIND_AUTO_CREATE);
I want to 'restart' the service. (Let's not argue why I want to do that)
I do that by:
unbindService(_serviceConnection);
// Do some initialization on service
bindService(new Intent(this, MainService.class), _serviceConnection, Context.BIND_AUTO_CREATE);
I noticed service doesn't die(onDestroy doesn't run) until I call next bindService();
So some static initialization I did on service got cleared by onDestroy() implementation.
Question: How do you make sure unbindService() will stop service (run onDestory()),
so that I could do initialization after and re-run bindService()?
I saw this in the "running services".. and i stopped it, what the hell is it and should i not have stopped it?

I can only assume that its eating away battery trying to see how is online and not. I certainly don't need this info unless I wish to go online myself... in which case I would actually go into the gtalk app.
ANyways, obviously i've been killing it in the running services, but it just comes back all on its own. ANy idea why or how to stop it?
