 Hi All,

How android system try to establish a data connection at the time of
power up or when we set up an apn.

 As I checked the framework code, DataConnection.java is a state
machine which interacts with RIL in order to activate/deactivate a
data connection. But when I put up any debug log in the
DataConnection.java ,it never gets hit either in success or failure
case.

When this file is used ?

Thanks,
Amit

1. Question about Preference Screen

Hi All:
    When I see the doc of Preference Screen, there is one paragraph
about the sub-preference screen related to dialog, the doc is as
follow:
    ---> When it appears inside another preference hierarchy, it is
shown and serves as the gateway to another          screen of
preferences (either by showing another screen of preferences as a
Dialog or via a Context.startActivity(android.content.Intent) from the
Preference.getIntent()). The children of this PreferenceScreen  are
NOT shown in the screen that this PreferenceScreen is shown in.
Instead, a separate screen will be shown when this preference is
clicked.
     But in Android Api Demo, the Preference from code, I find nothing
related to Dialog when using PreferenceScreen as the base element of
preference, and I have no idea about 'showing another screen of
preferences as a Dialog', what does it mean? Is there a pop-dialog
when we click anywhere in Preference Screen? But the Preference Screen
is invisible. So I wanna know if there is any suggestion about my
question, and thanks in advance!

2. Spreadsheet-like Grid?

Hi,
Is it possible to build a spreadsheet-like grid? I would like to
select single cells, or one row at a time,like a database viewer.

Or would it need to be implemented at the framework level?

I'm thinking of a UI equivalent of something like this AJAX control,
which may be opened in the WebView:

Thanks.
