 Hi everyone,

there is no ldd for android available in the ndk. is it available
somewhere else ?
It is useful when troubleshooting libraries.

i know it has already been been posted in a different list (http://
groups.google.com/group/android-platform/browse_thread/thread/
3e4a52d24373611c/e9503ff6bebb83b1?#e9503ff6bebb83b1) but no reply.

Cheers.

1. Accessing APNs on the phone

Hello,

How can I get the information on this phone regarding its number, carrier,
etc?

I have tried this:

String names = "";

Uri contentUri = Uri.parse("content://telephony/carriers/");

Cursor cursor = null;
try
{
cursor = getContentResolver().query(contentUri, new String[]{"name"}, null,
null, null);
if (cursor != null)
{
while (cursor.moveToNext())
{
String name = cursor.getString(0);
names+= name + "\n";
}
}
}
catch (Exception ex)
{
//Handle exceptions here
}
finally
{
if (cursor != null) cursor.close();
}


tv.setText("TestActivity:\n"+names);

But no success.

I get on the emulator screen:

2. Why does TextView.setText cause the enclosing ScrollView to scroll?

Hello!

I'm new to this group and (full disclosure) cross posting this
question here from StackOverflow, just because I'm not 100% sure how
my question will be found by other SO users (I made sure to read the
suggested "How To Ask Questions The Smart Way", and made sure to
search SO for a clear explanation, but I must have missed it).  Here,
I'm clear that it'll be sent out to everyone, so here goes (my
apologies in advance if I shouldn't be cross-posting like this!)




I've got this odd problem which is happening on 1.6, 2.2, and a
MyTouch 3G Slide (which is API #7, and listed as "2.1-Update1" in the
Android Device Chooser).

The basic idea for my app is to make a stopwatch-sort of thing, in
that the user can tap a button to start a timer, then tap it again to
stop (pause) the timer; further taps alternate between resuming the
timer and pausing the timer.

I've got a top-level ScrollView which contains a RelativelLayout,
which contains a bunch of widgets.  The first widget is a HUGE button
(so that it's easy to press), which pushes all my other widgets below
the bottom of the screen.  This is intentional, as I want to rely on
the ScrollView (and an on-screen reminder to the user) to make the
rest of the input options available.

I've got a simple state-machine type setup, where mState is the
current mode (STATE_TIMER_NOT_STARTED before the user presses any
buttons, ...RUNNING after the first press, and then ...PAUSED after
the second, back to ...RUNNING after the third, etc, etc).

All this works great EXCEPT that when the timer is running, and the
user presses the start/stop/resume button again, the ScrollView will
scroll down a ways.  I am NOT issuing this command (I don't even have
a reference to ScrollView object), and I'm not sure why it's doing
this.

REPRO:
Compile + run the below samples.  When the app starts, press the
'Start Timing' button.  Use your thumb (or the mouse) to touch-drag
the screen upwards (so you can see the RatingBar), then drag it back
downwards (so the button is again completely on-screen).  Tap the
button (which now reads 'PauseTiming') again, and it'll jump down a
bit.  It should NOT be jumping/scrolling down, since there's no
statement (that I can see) that tells it to scroll down.  As near as I
can tell, it's the setText that causes the scrolling ( when I comment
those lines out, no scrolling occurs).

WHAT I'M ASKING FOR:
If I'm doing something dumb & you could point out what it is, I'd
really appreciate it! :)
***    I wonder if 'touch mode' might have something to do with this,
since it does NOT appear to happen (in the emulator) when I use the
mouse's scroll wheel to move the panel upwards (i.e.,instead of the
simulated finger-dragging).  I can't find a whole lot on touch-mode,
and nothing specific on focus/selection in touch mode within a
ScrollView

If you can confirm that this error occurs for you too, that would be
ok, too (since misery loves company.*AHEM* I mean, since it might help
confirm that it's not just me :)   ).
