Android :: Stopping Widget's Service When Not In Use
Jun 3, 2010
I'm having trouble getting my widget to stop hogging so many resources.I setRepeating on the AlarmManager to update. When the widget is deleted (onDisabled()), I call .cancel() on the service, but the service still shows up in the android "running processes" making me believe I'm doing something wrong.Also, should I be scheduling my updates in the onEnabled() or the onUpdate()? onUpdate doesn't seem to work on anything other than the first widget.

I have an Android Service that is started by my application and does some things in a threadPool using Executors.newCachedThreadPool()
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?

How can I identify and stop single running services? More specifically, once I got the running services on a List as in a chunk of code like:
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE); List<RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE);
Is there any method to stop a single service, i.e to identify one and then stop it?

I have a Service which tracks the location of the user. Currently, the Service boots when the application starts and stops when the application terminates. Unfortunately, if users keep the application in the background, the Service never stops and drains battery.
I would like the Service to stop when my application is not in the foreground. I was hoping the Application class would let me Override onPause and onResume handlers, but it does not have them.

OS: Ice Cream Sandwich
Device: Motorola Xoom
I am having issues with a simple service not running correctly. The logcat shows some force stopping on the installed apk. Also the broadcast receiver should listen to android.intent.action.ACTION_POWER_CONNECTED but it is not.
This all worked on froyo 2.2 on a samsung galaxy tab.
Here is the snippet from logcat when I do an 'adb install testService.apk:
Code:
D/AndroidRuntime(15251):
D/AndroidRuntime(15251): >>>>>> AndroidRuntime START com.android.internal.os.RuntimeInit <<<<<<
D/AndroidRuntime(15251): CheckJNI is OFF
D/AndroidRuntime(15251): Calling main entry com.android.commands.pm.Pm
I/ActivityManager( 153): Start proc com.android.defcontainer for service
[code]....

I am writing application that has service that provides real time data to subscribers via remote callback mechanism. Now I wanted to add a widget that visualizes essential part of this data but got error: "IntentReceiver components are not allowed to bind to services". So what's the right way to get data from that service?

I have made a Android Widget which displays two articles (title + image). In addition to this, I have buttons for flipping backward and forward through the articles. What I don't understand is how I can change the Widgets RemoteViews when the buttons are pressed. Which should be one of the most basic operations in a widget, however, I can't seem to figure it out.
So... Can I do this with just a OnClickListener in the AppWidgetProvider? Or do I have to create an Activity without a window (visibility = false)?

I was interested in developing a clock widget for the homescreen and upon reading Home Screen Widgets tutorial, I wondered if there is a pre-existing Service I could reference for updating the current time rather than re-inventing the wheel?I download the Retro Clock application on my android phone and noticed that when I click it, it pops up the Alarm Clock settings, but with the default Google Analog Clock widget, upon click does nothing.Is that because the Retro Clock widget implements the Alarm Clock service? If so, how can I go about referencing that service? Or do I have this all wrong and misunderstood?

I am writing a widget on Android 1.6 that shows the minutes that a person has used on the current month.
The way I have it setup is by having a service that listens to the state of the phone and when the phone is picked up, it starts the timer and when the person hangs up, ends a timer. I would like to send this variable(long duration) over to my appWidgetProvider so I could update the edit text on it.

I'm having trouble starting a Service to update an AppWidget that I'm creating as an exercise. I'm trying to get the latitude and longitude of spoofed location data from DDMS to display in the widget. The widget uses a service to update the TextView, which may be slightly overkill, but I wanted to follow the template that seems to be common in AppWidgets that do more work (like the Forecast widget or the Wiktionary widget).
Right now, I'm not getting any error messages or strange behavior; nothing at all happens when the button is pressed. I'm a bit mystified as to what might be wrong. Could anyone out there point me in the right direction?
Additionally, if my logic for location is faulty, I'd love recommendations on that too. I've looked at several blogs, the Google examples, and the documentation, but I feel a little fuzzy on how it works.
Here is the current state of the widget:

I have an app widget that uses a Service to handle updates (as per the SDK sample). If a task killer kills the service, the widget obviously stops updating. Is there any way I can notify the widget that the service has been killed so it can attempt to restart it?

I have a widget that is supposed to start and stop a service (start it when it's not running, stop it when it is). This is working fine, however, each time the service is started, my app's main activity is also launched, which I don't want from the app's manifest, it works as I want it to (without launching the main-activity, just the service), but then I obviously don't have a main activity anymore.This is how I start the service (I would assume this is the normal way, and I can't see any reference to what might cause the MAIN intent to fire).

This tutorial uses service to avoid any ANR timeouts. I just wonder, can I use Thread instead of service to do the work of getting data and updating RemoteViews? I don't want to create a service, because Thread is easier to handle and pass data into Thread.

I have a AppWidget, after I delete it from HomeScreen it seems not stopping the AlarmManager attached with it. I have supported it with the AlarmManger, that call the ProviderImplementation class every 1 minute and in onReceive I put the code to call onUpdate. and in onDelete I explicitly stop the alarm, but it seems it is running continously and not stopping. any cure of it ?
I have stopped it with cancel(pendingintent) function.

My appWidget is working well. When it's installed and used by user, a Thread is launched to refresh view (like a flipper). Even if the screen is off, the thread is continuing...perfect for me... But after 3 minutes, it's stopped.
Does it a VM restriction avoiding some bad development usage?
How can I use this type of service? Develop a service in place of my thread?

I have both ADW and LP on my Droid. If I go into Settings/applications/ manage applications and select a launcher (that has widgets) and use the force stop option on the launcher, will the widgets set up with that launcher continue to run? Or would they be stopped as well? Would it matter if bother the running and stopped launcher had some of the same widgets?

Is it possible to stop an Android app from the console? Something like: adb stop com.my.app.package
It would speed up our testing process so much. Right now we uninstall/install the app each time to make sure the manual test cases start with a clean state.

My service spawns a new thread, and stops it according to the typically recommended java method of interrupt()'ing. When I stop the service, I stop the thread in onDestroy(). The service is stopped, and the interrupt code is reached. However, soon enough the thread restarts from the beginning of the Runnable.code...

I've installed Last.fm onto my desire for streamed music but I've noticed that it only plays 3-4 songs on average before stopping. the screen goes black which I guess means that it's going into sleep mode.

The Content Provider starts when the first applicable URI is resolved. This will make the ContentProvider run forever and there doesn't seem to be a way to stop it (such as due to inactivity etc).It would be nice if Content Provider would stop after some time so that the memory usage is reduced (An enclosing process, doesn't need to be alive if the Content Provider is not needed anymore).

I am rotating a view using rotateAnimation with this code new RotateAnimation(0, 360, w / 2, h / 2); I want to rotate this view infinitely, so i put setRepeatCount(RotateAnimation.INFINITE);
But the problem is after every one complete rotation, its stopping and starting again, means by default rotateAnimation have AccelerateDecelerateInterpolator(). I feel because of this. So if i put setInterpolator(null), its throwing null pointer exception. How to solve this.
I want to rotate my view without any lag.

And I have two buttons for it, 'Play' and 'Stop'.Problem is, after I press the stop button, and then press the Play button, nothing happens. -The stop button stops the song, but I want the Play button to play the song again (from the start) Here is my code:final MediaPlayer mp = MediaPlayer.create(this, R.raw.megadeth);And then the two public onclicks: For playing)
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
button.setText("Playing!");
try {
mp.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
And for stopping the track
final Button button2 = (Button) findViewById(R.id.cancel);
button2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
mp.stop();
mp.reset();
Can anyone see the problem with this? If so could you please fix it. (For suggest)

I'm trying to prevent my application to call the same method twice in the event of a double-click, or if the user presses different buttons quickly, almost at the same time.I have clickable Views, acting as buttons, that call the same method but passing different parameters.Inside this method I'm creating a new Thread, because it queries a web server for the result.The problem is that upon two quick clicks, the method is fired twice, two threads are created, and consequently two new activities are created. That makes my app crash.But this only seems to work on slower phones like the G1, I tried on Nexus and before it set blocked = true, the second request has was granted. So is there any way I can block the method being called if it's already running, or if the thread has started so it wont create a new one.

Is there any way to stop the Weather Chanel from broadcasting alerts. In San Francisco, wind and rain, constitute alerts. So this week there's a new alert every hour or two. I know it's raining and I know it's windy. It seems to be draining the battery.I've looked in the menu but I can't figure out how to stop the alerts from waking up my phone all the time. Any suggestions other than uninstalling?

In my game, I've got one activity starting another activity via an intent. When the user is finished with the second activity, they quit it using the back button. However, I have a problem: when this happens, the second activity is still running, even if it's quit with the back button.
My second activity will eventually give a "game over" message using a pop up window if there is no user input for a period of time. Problem is, when I back out of the second activity (where the game is happening) the "game over" message still appears eventually. This is how I know the second activity is still running. It even displays a "game over" message if my entire app is quit (on the Android OS).
How do I stop an activity completely when the user presses the back button?
