 I'm trying to launch a request to reflect changes in MapActivity. On a
simple Activity it works but not in MapActivity

Thanks in advance

1. Another AbsoluteLayout deprecation question

I have seen a number of threads discussing the deprecation of
AbsoluteLayout.  I'm a little fearful of reading third-party blogs
that suggest solutions to the deprecation because in some discussion
threads the Google employees have explicitly said the blogs contain
misunderstandings or inaccuracies.

So, I need to know how to implement my app's behavior without
AbsoluteLayout.  I would greatly appreciate any input people might
have, especially the real pros, the Android dev team who, by
deprecating AbsoluteLayout, must have a clear picture in their heads
of how to reorganize code to be up-to-date to achieve the same
functionality.  Romain Guy, Diane Hackborn, I'm looking your
direction.  :-)

The relevant part of my app is a single large View covering the
majority of the screen, a subclass of my own creation, whose onDraw
basically paints a complicated bitmapped canvas.  Subsequently, I
repeatedly add and remove (or set visibility to VISIBLE and GONE,
that's actually the approach I've taken) an EditText (also subclasses
with unique behavior) which I must frequently reposition to pixel
precision over the background canvas.  I currently do this by setting
up a new LayoutParams with the EditText's new location and then
calling AbsoluteLayout.updateViewLayout on the EditText.  Works like a

So, a single screen-spanning View drawn with a bitmap, overlaid with a
single EditText which must be positioned to pixel precision, and set
VISIBLE and GONE periodically, and be moved from location to location
from time to time.

Million dollar question: Without using AbsoluteLayout, what is the
official Android/Google endorsed method for implementing this
behavior?  FrameLayout and RelativeLayout seem -- at the least --
rather indirect in this situation where AbsoluteLayout provides a
literal interpretation of my app's behavior: one view positioned
arbitrarily over another view.  Am I incorrect?  Can one or both of
them achieve this behavior as painlessly as AbsoluteLayout?

Thank you.

2. Options for synchroinizing data between Android and backend database

Hi all,

Wanted to develop a mobile application for Android devices that stores
data locally and synchonizes (bidirectionally) local data with a
database server every 'N' minutes. That is, instead of building a web
application accesible from Android's browser that forces me to be
"always connected", I wanted to try the approach of "sometimes
connected" scenario.

I was thinking in using MySQL as server backend, but new to Android
and don't know which are the options to communicate and synchronize
data between mobile devices and servers. Is there any Android library
that makes this always hellish synchronization work easier?

What about Google Gears?

Thanks very much in advance.
