 Hi All,
I have a stupid question need you guys' help
Is it possible to simulate the touch screen event on android emulator?
Since I do not have real device to do this, I want to simulate the
event on emulator first.

If yes, how do I get started?
I tried to hook kernel image when runnig emulator. But log seems not
correct.(see following portion of logcat)

I/EventHub(   59): New keyboard: device->id=0x10000 devname='qwerty2'
propName='hw.keyboards.65536.devname' keylayout='/system/usr/keylayout/
qwerty.kl'
I/EventHub(   59): New device: path=/dev/input/event0 name=qwerty2
id=0x10000 (of 0x1) index=1 fd=52 classes=0x2f
E/EventHub(   59): could not get driver version for /dev/input/mouse0,
Not a typewriter
E/EventHub(   59): could not get driver version for /dev/input/mice,
Not a typewriter
I/KeyInputQueue(   59): Device added: id=0x0, name=qwerty2, classes=2f
I/KeyInputQueue(   59):   X: unknown values
I/KeyInputQueue(   59):   Y: unknown values
I/KeyInputQueue(   59):   Pressure: unknown values
I/KeyInputQueue(   59):   Size: unknown values
I/KeyInputQueue(   59): No virtual keys found

evne the keylayout nor the keychar are not what I expect to see
(I have register my keylayout and keychar in system.prop)

The final result I want to see is when I tap the mouse left key on
emulator software keyboard,
the logcat can display the X-Y coordinate and mapping keychar

The kernel version I use is android-goldfish-2.6.29, config is
goldfish_defconfig
Can anybody give me some clue? Any information will be helpful for me.

Thank you so much

2. Custom Account / Sync adapter: inability to edit contacts?

Hi!

When creating a custom account and/or sync adapter, raw_contacts that
belong to your custom account can be created.

But it looks like that they then cannot be edited with the Contact
app!

Is this a known limitation, or a problem in my code?

Thanks a lot for your help.
