Framework for backup/restore application's private data?

 A search framework is built in Android SDK1.6, where each application
can provide search suggestions for Quick Search Box.

I think we can build a similar framework to backup/restore app's
private data.

See following cases:
1) You already setup favorite channel names in FM radio. When you
change your phone, of course you want restore them from somewhere.
2) You have got a high mark in some game. After you change your phone,
you want the mark back.

Most backup/restore applications only focus on contacts, calendar,
Memos, tasks, emails, bookmarks, SMS, and some can handle more
(photos, videos, music) contents, but few care about application's
private data. I think Android should add this feature.

A public framework for such work is needed. Each app defines a public
method, say onAppSync(), which is called by a system-level backup/
restore manager (we can call it SyncManager) when it is needed (e.g.
when user requests or long time passed). The app defines what to
backup and even what format to use (referring to SyncML).

Once such a framework is available, old applications can also be
modified by defining a onAppSync() for it.

More technical details is left open. Are developers of the old
applications glad to see this?

1. ADC2 - Market Conflicting Names. GOOGLE, READ IT

It might be a good idea to rename the package name of your application
(it's a 2-click operation in Eclipse) rather than waiting for Google
people to remove your app from ADC2 version of Market as I think it is
probably the reason why you can't submit your app to the normal
Android Market.

Hope this helps.



2. in search for hardware/driver support infos

Hi Folkz!

me and a couple of friends are porting android to the Meizu M8.
We already have it up an running and stuff, but without the support
for the built in hardware.
So at this time, no GSM Wifi bluetooth etc is working, and i searched
the net a thousand times for informations regearding linux and the
hardware components.
So i decieded to write to this list in hope of finding someone who can
give a clue of where to find infos on these components.

First: The phone uses a samsung s3c6410 processor, and is roughly
based on the samsung smdk6410 bsd board.
We have android running, eg touchscreen/usb/sound works and now we are
trying to get some comunications to work,

1) Wlan: Its a SPI Samsung swl-2480 card, which is powerd by a marvell
8686 wlan chip. Driver for this module can be found in the kernel
wireless parts. The problem here is the spi interface.
Im trying to get a generic s3c_spi driver to compile and load. My
question is: would this be eneugh for android? can i assume that the
wlancard works with a spi master driver, or are such devices
controlled directyl trhough the interface without the need of a

2) GSM baseband.
There is a infineon s-gold 2 (pmb 8876) edge baseband processor used
in the device. Problem with this: i dont know nothing about it and
there are not much informations about this on the internet.
i already tried to send some AT to every UART but didnt got an answer.
I think the chip must be connected through an uart with the main cpu
and should roughly behave like a hayes compatible modem. But because
there no answers on the uart the chips is
a) not powerd on. Is there a need for such chips to get powerd on?
b) the device just dont answers to AT command like i expect.
c) the device is not connected through uart
Its the same baseband chip like in iphone, so i hop  anyone  has some
informations about this device and is willing to share his knowldge
with us.

Any help and any bit of informations are really appriciated
