[android-developers] Re: Screen rotation with App Widgets loses onClick connection

2012-05-11 Thread Opack 
Hi !

I seem to have the same problem but the solution I've found everywhere on 
the web and in this thread does not work for me :(

I posted my onUpdate method below, in which I perform a full initialisation 
of a new RemoteViews object. Then I pass it to the AppWidgetManager. This 
kind of operation (init + call to updateAppWidget) is done only in one 
place in whole my application : in this onUpdate method. Thus, I never send 
an incomplete RemoteViews object. This is why I don't understand why I 
suffer from the same screen orientation change problem :'(

I tried to call the onUpdate method from the onReceive method, and it works 
fine, but I think this solution is dirty, especially because I make this 
additional call to onUpdate on every call to onReceive (I cannot filter on 
some kind of on screen orientation changed message).

Here is the onUpdate method :
@Override
public void onUpdate(Context context, AppWidgetManager 
appWidgetManager, int[] appWidgetIds) {
final RemoteViews remoteViews = new 
RemoteViews(context.getPackageName(), R.layout.widget);

// Mise à jour de l'image dans les widgets
updateClockinImage(context,appWidgetIds, getCheckingCount(context));

// Build the intent to call the service
final Intent intent = new Intent(context.getApplicationContext(), 
AddCheckingService.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);

// Pour réagir à un clic il faut utiliser une pending intent car le 
onClickListener
// est exécuté par l'application Home
final PendingIntent pendingIntent = 
PendingIntent.getService(context.getApplicationContext(), 0, intent, 
PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.btn_checkin, pendingIntent);

// Mise à jour des widgets avec le nouvel intent
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
super.onUpdate(context, appWidgetManager, appWidgetIds);
}

Thanks in advance !!!

 I have an App Widget on the Home screen which works fine until the 
 screen is auto-rotated.  At that point, the onClick connection (set up 
 via a call to setOnClickPendingIntent) is lost.  The only way I seem 
 to be able to get it back is to delete the Widget from the Home screen 
 and then add it back.  Is there some kind of message that tells me 
 that the screen has rotated that I need to respond to (and reestablish 
 the connection)?

Each and every update you push to the wigdget with RemoteViews has to have
complete widget state, including all images, text, and pending intents.

There is no onUpdate on configuration changes. The home screen recreates
your widget, then takes the most recent RemoteViews and applies it to the
widget.

If your codes tries to update the widget incrementally, piece-by-piece, with
one RemoteViews specifying the intent, and another, repeated, update setting
some changing information, then you end up with the most recent RemoteViews
only having your changing text, but no PendingIntent.

This is very much unlike how Activities work, where the entire view
hierarchy is kept in memory for as long as the activity is on the screen
(and maybe longer).

 It is because, the widget becomes unresponsive when the display mode
 is changed from portrait to landscape. I had the same issue and I what
 I had done is for every RemoteView update I had send all the
 pendingintent to make it work

I figured that it was recreating the Widget on rotation.  The problem
is, I don't seem to be getting any messages to that effect, and have
no way (that I can see) of re-establishing the connection.  How can I
determine that a rotate has happened and set up a new onClick
connection?

Thanks

Like I said, you don't (determine or respond to an orientation change).

What you do, is make sure that every time your code pushes a RemoteViews
object into the home application for your widget, it's complete in all
respects:

- Has image resource ids;
- Has text stings;
- Has pending intents.

Don't do incremental widget updates, like you would do with a regular
activity - don't set the intents first, then the images, then the text
reflecting current information.

The home app runs as a separate process, and its state can get out-of-step
with your widget receiver. When it does, the only thing it has for
re-creating your widget is your most recent RemoteViews object. If it's
complete, and has all the parts, everything will work just fine. If it only
has the most recent text or image change, the earlier updates which had the
intents will be lost.
