[android-beginners] Problem with AppWidget Using a Service

2010-06-23 Thread Jake Colman 

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.

...Jake

Jake,

The error is in the way your code instantiates ComponentName.

Instead of:

ComponentName thisWidget = new ComponentName(this, ZMUpdateService.class);


Do this:

ComponentName thisWidget = new ComponentName(this,*ZmanMinderAppWidget*.class);


The error message was trying to convey same thing...

This means you are trying to state that ZMUpdateService is an
AppWidgetProvider, in one or more places in your code.

 public class ZMUpdateService extends Service {
  public void onStart(Intent intent, int startId) {
    RemoteViews updateViews = buildUpdate(this);
    ComponentName thisWidget = new ComponentName(this, ZMUpdateService.class);

Note: you are claiming your AppWidgetProvider is ZMUpdateService, when
it is really ZmanMinderAppWidget.

If it helps, here is a complete app widget example:

It assumes you have an identi.ca account you can use.
