SystemInfo API

This specification defines interfaces and methods that provide web applications with access to various properties of a system.

This API also provides interfaces and methods that can retrieve statuses of hardware devices, get the value of selected properties, and subscribe to asynchronous notifications of changes for selected values.

Web applications can use this API to access the following system properties:

  • ADS (Since: 3.0)
  • BATTERY
  • BUILD
  • CAMERA_FLASH (Since: 2.4)
  • CELLULAR_NETWORK
  • CPU
  • DEVICE_ORIENTATION
  • DISPLAY
  • ETHERNET_NETWORK (Since: 2.4)
  • LOCALE (Since: 2.1)
  • MEMORY (Since: 2.3)
  • NET_PROXY_NETWORK (Since: 3.0)
  • NETWORK
  • PERIPHERAL (Since: 2.1)
  • SIM
  • STORAGE
  • WIFI_NETWORK

Not all above properties may be available on every Tizen device. For instance, a device may not support the telephony feature. In that case, CELLULAR_NETWORK and SIM are not available.

To check the available SystemInfoPropertyId, getCapability() method can be used.

  • BATTERY - tizen.systeminfo.getCapability("http://tizen.org/feature/battery")
  • CAMERA_FLASH - tizen.systeminfo.getCapability("http://tizen.org/feature/camera.back.flash")
  • CELLULAR_NETWORK - tizen.systeminfo.getCapability("http://tizen.org/feature/network.telephony")
  • DISPLAY - tizen.systeminfo.getCapability("http://tizen.org/feature/screen")
  • ETHERNET_NETWORK - tizen.systeminfo.getCapability("http://tizen.org/feature/network.ethernet")
  • NET_PROXY_NETWORK - tizen.systeminfo.getCapability("http://tizen.org/feature/network.net_proxy")
  • SIM - tizen.systeminfo.getCapability("http://tizen.org/feature/network.telephony")
  • WIFI_NETWORK - tizen.systeminfo.getCapability("http://tizen.org/feature/network.wifi")

Since: 1.0

The function must asynchronously acquire the current value of the requested property. If it is successful, the successCallback must be invoked with an object containing the information provided by the property.

The ErrorCallback function can be launched with these error types:

  • NotSupportedError - If the given property is not supported (since Tizen 2.3).

Remark: If the given property is not supported, NotSupportedError would be passed through a ErrorCallback() since Tizen 2.3.

Remark: If system provides more than one value for the system property, the primary (first) system property is returned through SystemInfoSuccessCallback.

Parameters:

  • property: The name of the property to retrieve.
    • Conditional privilege: For using CELLULAR_NETWORK value, privilege http://tizen.org/privilege/telephony (public level) is needed since Tizen 2.4.
  • successCallback: Callback function called when the properties are successfully retrieved.
  • errorCallback [optional] [nullable]: Callback function called when an error occurs while retrieving the properties.

Exceptions:

}

function onErrorCallback(error)
{
  console.log("An error occurred " + error.message);
}

tizen.systeminfo.getPropertyValue("CPU", onSuccessCallback, onErrorCallback);

Code example:

function onSuccessCallback(cellular)
{
  console.log("The status of the cellular network is " + cellular.status);
}

function onErrorCallback(error)
{
  console.log("An error occurred " + error.message);
  /* If telephony_capability is false but getPropertyValue("CELLULAR_NETWORK, ...) is called, */
  /* NotSupportedError is passed. */
}

var telephony_capability =
    tizen.systeminfo.getCapability("http://tizen.org/feature/network.telephony");

if (telephony_capability === true)
{
  /* onSuccessCallback will be invoked. */
  tizen.systeminfo.getPropertyValue("CELLULAR_NETWORK", onSuccessCallback, onErrorCallback);
}
else
{
  console.log(
      "Telephony feature is not supported. Cellular network related information cannot be retrieved.");
}
getPropertyValueArray
Gets the current values of a specified system property. 
void getPropertyValueArray(SystemInfoPropertyId property, SystemInfoPropertyArraySuccessCallback successCallback,
                           optional ErrorCallback? errorCallback);

Since: 2.3

It is recommended that you check if a device provides one or more than one value for a particular system property via getCount().

If one particular system property is provided on a device, it returns an array containing one SystemInfoProperty object through SystemInfoPropertyArraySuccessCallback method.
If more than one particular system property is provided, multiple SystemInfoProperty objects are returned.

The ErrorCallback function can be launched with these error types:

  • NotSupportedError - If the given property is not supported.

Remark: See getCount().

Parameters:

  • property: The name of the property to retrieve.
    • Conditional privilege: For using CELLULAR_NETWORK value, privilege http://tizen.org/privilege/telephony (public level) is needed since Tizen 2.4.
  • successCallback: Callback function called when the properties are successfully retrieved.
  • errorCallback [optional] [nullable]: Callback function called when an error occurs while retrieving the properties.

Exceptions:

  • WebAPIException

    • with error type SecurityError, this error is only thrown for CELLULAR_NETWORK property when an application does not declare http://tizen.org/privilege/telephony privilege in config.xml.

    • with error type TypeMismatchError, if the input parameter is not compatible with the expected type.

Code example:

function successCB(property)
{
  console.log("The SIM's current state is " + property.state);
}

function successArrayCB(properties)
{
  console.log("The number of the returned system properties is " + properties.length);
  for (var i = 0; i < properties.length; i++)
  {
    console.log("[" + i + "] SIM's state is " + properties[i].state);
  }
}

var count = tizen.systeminfo.getCount("SIM");
if (count === 0)
{
  console.log("This device does not provide SIM card.");
}
else if (count > 1)
{
  tizen.systeminfo.getPropertyValueArray("SIM", successArrayCB);
}
else
{
  tizen.systeminfo.getPropertyValue("SIM", successCB);
}
addPropertyValueChangeListener
Adds a listener to allow tracking changes in one or more system properties. 
unsigned long addPropertyValueChangeListener(SystemInfoPropertyId property, SystemInfoPropertySuccessCallback successCallback,
                                             optional SystemInfoOptions? options, optional ErrorCallback? errorCallback);

Since: 1.0

When called, it immediately returns and then asynchronously starts a watch process defined by the following steps:

1. Register the successCallback to receive system events that the status of the requested properties may have changed.

2. When a system event is successfully received, invoke the associated successCallback with an object containing the property values.

3. Repeat step 2 until removePropertyValueChangeListener function is called.

There are device properties which are never changed (e.g. "BUILD") and properties which are not changed on some devices (e.g. "DEVICE_ORIENTATION" in Tizen TV device). The addPropertyValueChangeListener() method accepts any identifier of these properties, but the listener added for them will not be invoked.

The errorCallback can be launched with any of these error types:

  • NotSupportedError - If the given property is not supported (since Tizen 2.3).
    For example, monitoring CELLULAR_NETWORK changes is not supported on a device which does not support the telephony feature.

Remark: The errorCallback() is newly added as an optional parameter since Tizen 2.3.

Parameters:

  • property: The name of the property to retrieve.
    • Conditional privilege: For using CELLULAR_NETWORK value, privilege http://tizen.org/privilege/telephony (public level) is needed since Tizen 2.4.
  • successCallback: Callback function called when the properties are successfully retrieved.
  • options [optional] [nullable]: An object containing the various options for fetching the properties requested. See details.
  • errorCallback [optional] [nullable]: Callback function called when an error occurs.

Return value:

    unsigned long: An identifier used to clear the watch subscription.

Exceptions:

  • WebAPIException

    • with error type InvalidValuesError, if any of the input parameters contains an invalid value (e.g. the invalid value for options).

    • with error type SecurityError, this error is only thrown for CELLULAR_NETWORK property when an application does not declare http://tizen.org/privilege/telephony privilege in config.xml.

    • with error type TypeMismatchError, if the input parameter is not compatible with the expected type.

    • with error type UnknownError in any other error case.

Code example:

function onSuccessCallback(cpu)
{
  console.log("The cpu load: " + cpu.load);
}

tizen.systeminfo.addPropertyValueChangeListener("CPU", onSuccessCallback, {lowThreshold: 0.2});
addPropertyValueArrayChangeListener
Adds a listener to allow tracking of changes in one or more values of a system property. 
unsigned long addPropertyValueArrayChangeListener(SystemInfoPropertyId property,
                                                  SystemInfoPropertyArraySuccessCallback successCallback,
                                                  optional SystemInfoOptions? options, optional ErrorCallback? errorCallback);

Since: 2.3

The ErrorCallback function can be launched with these error types:

  • NotSupportedError - If the given property is not supported (since Tizen 2.3).
    For example, monitoring CELLULAR_NETWORK changes is not supported on a device which does not support the telephony feature.

There are device properties which never change (for example "BUILD") and properties which do not change on the current platform (for example "DEVICE_ORIENTATION" for some platforms). The addPropertyValueChangeListener() method accepts any identifier of these properties, but the listener added for them will not be invoked.

Parameters:

  • property: The name of the property to retrieve.
    • Conditional privilege: For using CELLULAR_NETWORK value, privilege http://tizen.org/privilege/telephony (public level) is needed since Tizen 2.4.
  • successCallback: Callback function called when the properties are successfully retrieved.
  • options [optional] [nullable]: An object containing the various options for fetching the properties requested.
  • errorCallback [optional] [nullable]: Callback function called when an error occurs.

Return value:

    unsigned long: An identifier used to clear the watch subscription.

Exceptions:

  • WebAPIException

    • with error type InvalidValuesError, if any of the input parameters contains an invalid value (e.g. the invalid value for options).

    • with error type SecurityError, this error is only thrown for CELLULAR_NETWORK property when an application does not declare http://tizen.org/privilege/telephony privilege in config.xml.

    • with error type TypeMismatchError, if the input parameter is not compatible with the expected type.

    • with error type UnknownError in any other error case.

removePropertyValueChangeListener
Unsubscribes notifications for property changes. 
void removePropertyValueChangeListener(unsigned long listenerId);

Since: 1.0

If a valid listenerId argument is passed that corresponds to an existing subscription, then the watch process must immediately terminate and no further callback is invoked.

Parameters:

Exceptions:

  • WebAPIException

    • with error type InvalidValuesError, if any of the input parameters contains an invalid value.

    • with error type TypeMismatchError, if the input parameter is not compatible with the expected type.

    • with error type UnknownError in any other error case.

Code example:

var id = null;
function onSuccessCallback(cpu)
{
  console.log("New value for CPU load is " + cpu.load);
  if (id != null)
  {
    /* After receiving the first notification, clear it. */
    tizen.systeminfo.removePropertyValueChangeListener(id);
  }
}

id = tizen.systeminfo.addPropertyValueChangeListener("CPU", onSuccessCallback);
