Hi I am trying to actually simulate a vibrator device inside the
emulator .A timed_output driver for the vibrator was created and i am
able to access the node at /sys/class/timed_output/vibrator/enable
that is specified as THE_DEVICE in the vibrator.c file at hardware/
libhardware/vibrator/.The driver is tested to work from the kernel
below
I ran into some issue while trying to invoke the driver from a user
level app.I just added these two lines and created an app.
vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(10000);
when i created an .apk and ran it i could see the following messages
in Logcat
I/ActivityManager( 589): Starting activity: Intent
{ action=android.intent.action.MAIN categories=
{android.intent.category.LAUNCHER} flags=0x10200000
comp={com.uiactivity.ui/com.uiactivity.ui.uiSimpleWidet} }
I/ActivityManager( 589): Start proc com.uiactivity.ui for activity
com.uiactivity.ui/.uiSimpleWidet: pid=791 uid=10023 gids={}

com.uiactivity.ui.uiSimpleWidet}} with isForward=true
I/ActivityManager( 589): Displayed activity
com.uiactivity.ui/.uiSimpleWidet: 1203 ms
Do i have to do something specific to make sure that the Harware
service kicks in after this.?
After this nothing happens ,
is it guaranteed that VIBRATOR_SERVICE will automatically be binded
when i do this
vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
because i dont really see a error there.
could some one throw some light on it
Is there a way i can verify VIBRATOR_SERVICE is actually running in
the emulator .( i made sure the libhardware.so and
libhardware_legacy.so are present )I could see from ddms service
hardware is running .
