Android :: Scheduling Repeat Task And Being Notified
Mar 15, 2009
I'm trying to find the "correct" way to do the following:
I have an activity with a button that starts a repeating task in the background. That is, if the user goes away from my activity, I want my task to still be scheduled and executed every x minutes. I want a status TextView to be displayed on the activity, and if the task happens to start executing while my activity is showing, the TextView should be updated so the user can be aware of what's going on. So basically, is there a way to start a scheduled background repeating task and be notified when it is executed? From what I saw in the sample applications, I understand I'm supposed to use AlarmManager and a Service but I'm not sure about the notification part.

I would like to know whenever the top task is changing. i.e. when a new task is starting or a task is finishing or when the current active task changes. Is there an intent that is sent that I can listen to?

My blackberry allowed me to program when my phone would shut off in the evening and turn on in the morning. Is there anything similar?
My wife has a habit of forgetting to lower the volume on her phone at night so we hear her reminders and such all night long (or at least until I get up and silence her phone)

I updated my app to use the "new" startForeground() method of Service. Now beta testers are complaining about the foreground app going slow. Is that a coincidence or does startForeground() mess with the thread's prio or does anything else but what is written below? Just as an additional information the background activity does some syncing, reports the progress to the notification using remote views and as it is not latency dependent I use (and did that before already) this: Process.setThreadPriority(Process.THREAD_PRIORITY_LOWEST);
Should I use another Priority? And if it makes any difference, how does that play with Android 1.5 devices?

I am writing a demo app that allows the user to set a number of times they want my app to run. The app has no interface and just puts shows some notifications. Running this as a service seems the most obvious.

I have a class that extends Application. In the class I make a call to AlarmManager and pass in an intent. As scheduled my EventReceiver class, that extends BroadcastReceiver, processes the call in the onReceive method. How would I call the intent again from the onReceive method to schedule another event?

In the 1.6 API, is there a way to ensure that the onStart() method of a Service is called after the service is killed due to memory pressure?

In the 1.6 API, is there a way to ensure that the onStart() method of a Service is called after the service is killed due to memory pressure? From the logs, it seems that the "process" that the service belongs to is restarted, but the service itself is not. I have placed a Log.d() call in the onStart() method, and this is not reached.

My internet package is capped but has unlimited usage between 2am to 8am. I have an internet stick (MK808B) running rooted jelly bean connected to my TV that I want to use as an overnight torrent client, but am having no luck finding a solution to the scheduling problem.
I've looked for an android torrent client with a scheduler or a firewall application that can block an app during specific times of day, but have found neither.

I'm writing an android program for adding task and deleting task in listview. I've add an onClickListener to the delete button so it can delete the task. However I was told I should not have the listener in the adapter violating mvc. how I can remove a task in my TaskListItem class. I got the method removeTask() in the adapter, but don't how I can use it in the TaskListItem class.
Code:
public TaskListItem(Context context, AttributeSet attrs) {
super(context, attrs);
mContext = context;

This is quick and easy. Can I get a sampling of what people are using for podcasting apps and likes/dislikes? Here is what I want to be able to do:
1. ESPN-"type" podcasts (scheduled, generally weekly, etc.)
2. Semi-"custom" podcasts (hometown newspaper podcasts, generally not scheduled)
Would preferably like something I can schedule to download at night.

Is there an app for having a text to be sent at a certain time or a certain place (using GPS)? I was curious because I need to send a text to someone at 5 AM to remind them of something. I'll be asleep, of course.
I thought I remembered reading about something at the Google Apps Innovation conference from last November or so, or an app like this.

I have connections in all different time zones, and I used to schedule my texts to go out during their daytime hours. Now with 4.3, I do not seem to have that option.

Finally bought my Droid last week, and am very glad to have done so. My first smart phone, and I'm having a blast. One question about FB notifications. Is there any way to change what you get notified for? Right now i only get notified for pokes. It'd be nice to hear "Droid" when someone posts on my wall or something. Any ideas?

I'm wondering if there is any way to get notified when applications are installed. I'd like to install my app as a service which just waits to be notified on app installation.

Can I be notified of the following events for an Activity: I realize that I can probably override the main View's onSizeChanged() and be notified when the View has changed, but how can I be notified when it's about to change?

Is there an app for choosing which apps you want to use that are already open or whatever. Or is there a button you can press to bring up a task list like you do with you blackberry when u hold the blackberry key and the list of open apps comes out.

I am listening events from accelerometer sensor and everything is going right. The problem occurs when phone gets in standby mode and I am not being notified by sensors anymore. Does Anyone know if it's possible to get sensor notifications, by implementing a listener, even if phone is in standby?

I have a list view with array adapter to show user some information that retrieved from Internet, As we all know reading data from Internet requires some time to finish, but if I try to read data on getView(), it means user must wait and he/she cannot see anything at that time, the screen is black for long a time because it will cost too much time to finish. This is unacceptable.
So I think maybe I can show user a empty list view first and then display a progress dialog to let user know I'm now just reading data. The background task will read data and send message to UI thread when job is done. But there's one problem: I don't know how to get notified when list view is displayed. I mean, I want to know when & where to show that progress dialog when I first show user an empty list?

Is it possible to be notified in Android when the Audio system starts playing audio? it looks like i should wire up a BroadcastReceiver, but it's not clear what i would listen for. I could listen for the MediaPlayer intent, but that would only capture when that particular application was playing audio, not when a third party application played audio, etc.

I've been using Task Panel X and Advanced Task manager to kill unneeded tasks and keep memory at a maximum.
Recently, every time I open Task Panel X and then revert back to Home screen I get the HTC logo and then a loading screen while the device sets itself. This happens even if I kill NO tasks.
So my solution was to uninstall Task Panel X and then use just Advanced Task Manager. All the sudden, same result.
Everytime I open either of these apps and then go back to home screen I get a BLACK SCREEN WITH HTC LOGO, THEN A BRIEF (10 SECONDS) LOADING SCREEN. THEN ALL IS NORMAL.

I was wondering is it possible to get a notification of when a new configured network is added to the Wifi Manager in Android? I know you can get the current list of configured networks.
http://developer.android.com/intl/de/reference/android/net/wifi/WifiM...
But is it possible to get notification of when a new one is added? I don't see anything in the Wifi Manager that would be helpful. How this could be achieved?

Does Android provide a notification of being in vicinity of a new Wifi Network? Whether the device is configured to connect to that wifi network depends on whether the device has the wifi configuration set for that particular wifi network, but is it possible to get notification whenever entering any new wifi network?
I saw the WifiManager class but the states inside the class do not seem to achieve what I am trying to do. Any ideas?
