[android-beginners] Checking for App before Launching
When my user clicks on my AppWidget, I want to launch either my own provided activity or an activity from a different app if that app is installed. My own activity is a stripped down version of the information that can be displayed by that other application. If that other application is available, I'd prefer to launch it in instead of my own. I may include this as a preference option and allow the user to decide which activity to launch. How can I check whether a specific app is installed before attempting to launch it (or before including it in my preferences) and only launch my own activity if that app is not available?

[android-beginners] Canceling an Alarm in an AppWidget
My AppWidget's onEnabled method creates two PendingIntents. The first
is to get location updates and the second is for an ELAPSED_REALTIME
alarm. The two PendingIntents are declared as private class-level
variables so that I can access them later from different methods
(obviously). I'm having trouble canceling these PendingIntents and it
looks like its because the variable has become null. In the case of
location updates, I crash when I execute LocationManager.removeUpdates.
In the case of the alarm, I do not crash but the alarm is not canceled.
I tried putting my cancel code in onDisabled and onDeleted (not at the
same time) but it didn't work. Any suggestions?
My code looks as follows:
public void onDeleted(Context context, int[] AppWidgetIds) {
Log.d(ZMAppWidget, onDeleted);
// cancel location updates
LocationManager lm = (LocationManager) context
.getSystemService(Context.LOCATION_SERVICE);
lm.removeUpdates(piLocation);
// cancel the alarm used to update the time
AlarmManager alarms = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
alarms.cancel(piAlarm);
}

Justin,
What you saying is certainly true generically. But I am specifically
talking about a class as follows:
public class JakeService extends Service {
}
In example code I don't think I usually see calls up to the super
implementations. That seems wrong. So when extending the Service class
do you call super before or after you do your own work? Wouldn't the
answer to this question be the same regardless of what my Service
implementation does?

[android-beginners] Flurry and AppWidgets
I am familiar with using Flurry with Activities and calling FlurryAgent.onStartSession() in the activity's onStart() method and calling FlurryAgent.onEndSession in the activity's onStop() method. What would be the best way to do the same thing if I want to use Flurry with my appwidget? Should I use the onEnabled()/onDisabled() methods or should I use onUpdate() since the user may never delete my appwidget and I won't know he's still using it? Or maybe onUpdate() and onDisabled() but then I won't be matching my start/end sessions. If my appwidget has a configuration activity or some other displayed activity I can obviously use flurry there.

I don't want the user to think that a GPS is required in order for the application to work. But I do need to get lat/long one way or the other. 2) Is best practice still to do a backwards search through the list of available providers and to use the best one I find? 3) When setting up the location listener or intent to track location changes you have to specify the provider to use. But what if want to simply use the cheapest provider available?

[android-beginners] Triggering an AppWidget Update
I have some questions about the correct approach for updating an AppWidget's display. Since this is a beginners forum, please let me state what I already do know: 1) I can use android::updatePeriodMillis to specify the update interval. When this interval has elapsed the phone is woken up. Intervals of less than one hour are not a good idea. 2) Updates can be triggered by an alarm that will not actually wake up the phone. What I'm confused about is how/why/when to trigger an update. Let's say I am creating an AppWidget that will display the time of my next appointment. The widget needs to know the current time and the time of my next appointment. When the current time is after the current appointment the widget has to display the time of the next appointment. For this widget to work it must be regularly checking the time and the calendar since at any minute it might be time to display the next appointment. Does this mean I have to update the widget's display every minute? Clearly not, but how else? In actuality, I only really need to update the display if the user is looking at the screen. But do we only update if the screen is active? If so, what about if that update is a time-consuming process? The UI would then appear non-responsive. So what the is correct approach for this kind of problem?

Kostya, This is actually a theoretical discussion since I'm trying to understand how this type of problem, as opposed to this actual problem, can be solved. If the data to be updated is fixed, then it sounds like you would want an intent to be fired when the data changes. So in my first example, the problem can be solved by firing an intent when the appointment time has passed so that you get the time of the next appointment or forcing an update when the a new appointment is added. But in the second example, would it be appropriate to update every minute? But Android 2.2 only allows an update every 30 minutes. Do you set an alarm to trigger even minute or would that also drain the battery? Do you trigger an update only when the screen is turned on? Can that even be detected? -- Jake Colman -- Android Tinkerer -- You received this message because you are subscribed to the Google Groups Android Beginners group. NEW!

[android-beginners] Problem with AppWidget Using a Service
I am trying to create a simple AppWidget using a service to initialize
the content in the onUpdate() method. The data is not being refreshed
and logcat shows me the following warning:
AppWidgetService W updateAppWidgetProvider: provider doesn't exist:
ComponentInfo{com.jnc.zmanminder/com.jnc.zmanminder.ZMUpdateService}
I must be missing something obvious but I cannot figure it out.
My AppWidget class (edited for brevity) looks as follows:
public class ZmanMinderAppWidget extends AppWidgetProvider {
public void onUpdate(Context context,
AppWidgetManager appWidgetManager, int[] appWidgetIds) {
context.startService(new Intent(context, ZMUpdateService.class));
}
}
My Service class (edited for brevity) looks as follows:
public class ZMUpdateService extends Service {
public void onStart(Intent intent, int startId) {
RemoteViews updateViews = buildUpdate(this);
ComponentName thisWidget = new ComponentName(this, ZMUpdateService.class);
AppWidgetManager manager = AppWidgetManager.getInstance(this);
manager.updateAppWidget(thisWidget, updateViews);
}
public IBinder onBind(Intent arg0) {
return null;
}
public RemoteViews buildUpdate(Context context) {
Time time = new Time();
time.setToNow();
RemoteViews views = new
RemoteViews(context.getPackageName(),R.layout.widget);
views.setTextViewText(R.id.time, time.format(%I:%M%p));
return views;
}
}
The ZMUpdateService service is defined in my manifest file.
Thanks for any help.

[android-beginners] Re: Problem with AppWidget Using a Service
Kostya,
Thanks. That worked like a charm.
I noticed in sample AppWidget code that does not use a service, that it
iterates the appWidgetIds array so that it updates all instances of the
widget. However, in sample code that uses a Service, that iteration is
not done. Is that because it is not needed for some reason? How would
one update multiple instances using a service-based solution?
Thanks.

[android-beginners] Re: Problem with AppWidget Using a Service
Kostya,
That makes perfect sense. It seems like a service-based update is
really the right way to go. It avoids any potential timeout issue and
is allows updating of all widgets at once.
Thanks for your help.

KV == Kostya Vasilyev kmans...@gmail.com writes:
KV Jake,
KV onUpdate is passed an explicit list of just the widget ids that
KV need to be updated. Supposedly, there could be widgets that
KV belong to this provider but don't need updating (e.g. on a
KV scrolled-off home screen portion).
KV Pushing a RemoveViews object to a paricular widget is done by
KV calling:
KV manager.updateAppWidget(int widgetId, updateViews);
KV It's also possible to update all widgets that belong to a
KV particular widget provider, and this is the approach
KV service-based widgets take, supposedly to avoid paying service
KV start-up costs for each widget id.
KV In this case, a single RemoteViews is pushed to all widgets with
KV a single call to:
KV manager.updateAppWidget(ComponentName thisWidget, updateViews);
