Jerome,
Right, you can't tell which widget is which by using just AppWidgetManager.
If you need to do this, and by "the current widget that the user
interacts with" you mean the widget the user clicks on.... I suggest you
use PendingIntent's that you can differentiate in the receiver. Using
different "request id" with PendingIntent.getBroadcast is one way to do it.
As for getAppWidgetIds problem: if you're stil not getting any values at
all (array.length == 0), please post your code. The manifest declaration
of your widget provider, the code that calls getAppWidgetIds, and any
relevant code around it.

Hi Kostva,
Long time no access.
The widgetprovider name is right.
Refer to "which widget coming", I meant that if the same widget
provider has different widget instances on Home Screen, then we can
not know what is the ID of the current widget that the user interacts
with.
Through getAppWidgetIds() method, I wanted to get how many instances
of widget that the same widget provider owns. But it failed.
I still have no idea of this.
Thanks

Make sure that ComponentName you use to get AppWidgetManager matches the
widget provider in the manifest. If it doesn't, you'll get an empty list
(ids.length = 0, the loop won't execute).
Not sure what you mean by "which widget coming".

Hi guys,
I have searched many topics about AppWidgetManager.getAppWidgetIds().
But I don't get any compellent answers. In my code, I first get all
widget ids by
AppWidgetManager.getAppWidgetIds(provider), and then do a for loop as
below:
for (int id : ids) {...}
However, I see the for loop never executed. And if I call ids.length,
the sentence never executed yet.
Some people said getAppWidgetIds() can not return the right id set,
that is because the some widgets were deleted but their ids are still
there.
My target is to know how many widgets are created by the specified
widget provider, so I think getAppWidgetIds() can meet this. But it
fails now.
I think getAppWidgetIds() has something wrong, and the widget
framework should fix this. Also, in widget provider, if it can
distinguish which widget instance is coming, that means the current
widget id can be passed in, then all things will be better. Why not do
this in widget framework?
