vibration is not working 
int error, num;
error = device_haptic_get_count(&num);
haptic_device_h handle;
haptic_effect_h effect_handle;
error = device_haptic_open(0, &handle);
error = device_haptic_vibrate(handle, 1000, 1000, &effect_handle);

hello,

This is my code I learned this from haptic(not vibration) guide at the below link:

https://developer.tizen.org/documentation/guides/native-application/system/device

 

But my Z1 device is not vibrating at all,

Is there anyone who succesfully vibrate Z1 device in native app?

Hello,

First of all, have you added the http://tizen.org/privilege/haptic privelege to your tizen-manifest.xml file?

Xaemin Cho

Yes, I already added this

<privileges>
    <privilege>http://tizen.org/privilege/systemsettings</privilege>
    <privilege>http://tizen.org/privilege/haptic</privilege>
</privileges>

I got answer by myself

 

The 3rd parameter means level of vibration.

It should be ranged from 0 to 100.

My Z1 is vibrating now when I set this value under 100.

Hi,

Strange!!!

My Z1 no working. What's wrong in my code, or am I mis-understand?

Sample code:

haptic_device_h handle;
haptic_effect_h effect_handle;
int error, num;
error = device_haptic_get_count(&num);
dlog_print(DLOG_INFO, LOG_TAG, "[device_haptic_get_count] num:%d, error:%d",num,error);

error = device_haptic_open(0, &handle);
dlog_print(DLOG_INFO, LOG_TAG, "[device_haptic_open] error:%d",error);
error = device_haptic_vibrate(handle, 5000, 99, &effect_handle);
dlog_print(DLOG_INFO, LOG_TAG, "[device_haptic_vibrate] error:%d",error);
error = device_haptic_stop(handle, effect_handle);
dlog_print(DLOG_INFO, LOG_TAG, "[device_haptic_stop] error:%d",error);
error = device_haptic_close(handle);
dlog_print(DLOG_INFO, LOG_TAG, "[device_haptic_close] error:%d",error);

Dlog:

Hi, you can check 2 things,

 

1. Did you add proper privilege into Manifest like this?

    <privileges>
     <privilege>http://tizen.org/privilege/haptic</privilege> 
    </privileges>

 

2. Do not call stop API right after vibrate API.

   In my case, I didn't call device_haptic_stop and device_haptic_close for testing.

Hi,

thanks a lot, it's works fine! :)

haptic_device_h handle;
haptic_effect_h effect_handle;
int error;

error = device_haptic_open(0, &handle);
dlog_print(DLOG_INFO, LOG_TAG, "[device_haptic_open] error:%d",error);
error = device_haptic_vibrate(handle, 5000, 99, &effect_handle);
dlog_print(DLOG_INFO, LOG_TAG, "[device_haptic_vibrate] error:%d",error);

What are you guys doing in this thread?

Anyway, 

Did you check the main loop?

device_haptic_vibrate is not blocking function, maybe It use mainloop internally.

So If your application doesn't have mainloop, this function doesn't work.

And if you call not it in main thread, (if you call it in another thread) I think it should be not working.

I don't have real Z1 device, and emulator don't have vibrator. so I can't test it. but I think it's almost be right.
