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:

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)
NETWORK
NET_PROXY_NETWORK (Since: 3.0)
PERIPHERAL (Since: 2.1)
SIM
STORAGE
VIDEOSOURCE (Since: 2.3)
WIFI_NETWORK
ADS (Since: 3.0)

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, tizen.systeminfo.getCapability() 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")

This API offers methods for retrieving system information and for subscribing notifications of system information changes.

Methods

getTotalMemory

Gets the total amount of system memory (in bytes).

long long getTotalMemory();

Since: 2.3

Exceptions:

WebAPIException

Code example:

 // To get total amount of system memory
 console.log("The total memory size is " + tizen.systeminfo.getTotalMemory() + " bytes.");

getAvailableMemory

Gets the amount of memory that is not in use (in bytes).

long long getAvailableMemory();

Since: 2.3

Exceptions:

WebAPIException

Code example:

 // To get total amount of system memory
 console.log("The available memory size is " + tizen.systeminfo.getAvailableMemory() + " bytes.");

getCapabilities

Gets the capabilities of the device.

Deprecated. Deprecated since 2.3. Instead, use getCapability().

SystemInfoDeviceCapability getCapabilities();

Since: 2.0

The function must synchronously acquire the capabilities of the device.

Exceptions:

WebAPIException
- with error type UnknownError in any error case.

Code example:

 var deviceCapabilities;
 deviceCapabilities = tizen.systeminfo.getCapabilities();
 if (deviceCapabilities.bluetooth) {
     console.log("Bluetooth is supported");
 }

getCapability

Gets a device capability related to a given key.

any getCapability(DOMString key);

Since: 2.3

See the available device capability keys. The additional keys for the custom device capability are specified by OEM's and vendors.

Parameters:

key: The device capability key for the device or additional custom device capability key specifies by OEM's

Return value:

any The value of the specified device capability

Exceptions:

WebAPIException
- with error type UnknownError in any other error case.

Code example:

 try {
     // Checks if a device supports bluetooth API or not
     var bluetooth = tizen.systeminfo.getCapability("http://tizen.org/feature/network.bluetooth");
     console.log(" Bluetooth = " + bluetooth);
 } catch (error) {
     console.log("Error name: " + error.name + ", message: " + error.message);
 }

getCount

Gets the number of system property information provided for a particular system property.

long getCount(SystemInfoPropertyId property);

Since: 2.3

That is the length of array retrieved by the getPropertyValueArray() method for the given property.

Parameters:

property: The name of the system property

Return value:

long The number of property values for the given property. If the property is not supported, 0 is returned.

Exceptions:

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

Code example:

 var count = tizen.systeminfo.getCount("SIM");
 if (count === 0) {
     console.log("There is no available SIM card.");
 } else {
     console.log("There is(are) " + count + " SIM card(s) available.");
 }

getPropertyValue

Gets the current value of a specified system property.

void getPropertyValue(SystemInfoPropertyId property, SystemInfoPropertySuccessCallback successCallback, optional ErrorCallback? errorCallback);

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 method 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.
successCallback: Function called when the properties have been successfully retrieved.
errorCallback [optional] [nullable]: Function called when an error occurred while retrieving the properties.

Exceptions:

WebAPIException
- with error type TypeMismatchError, if the input parameter is not compatible with the expected type.
- with error type UnknownError in any other error case.
- 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.

Code example:

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

 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 would be 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 method 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.
successCallback: Callback method that is invoked when the properties have been successfully retrieved.
errorCallback [optional] [nullable]: Callback method that is invoked when an error occurs while retrieving the properties.

Exceptions:

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

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 of 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.
successCallback: Function called when the properties have been successfully retrieved.
options [optional] [nullable]: An object containing the various options for fetching the properties requested. See details.
errorCallback [optional] [nullable]: Function called when an error occurred.

Return value:

unsigned long An identifier used to clear the watch subscription.

Exceptions:

WebAPIException
- with error type TypeMismatchError, if the input parameter is not compatible with the expected type.
- with error type InvalidValuesError, if any of the input parameters contain an invalid value (e.g. the invalid value for options).
- with error type UnknownError in any other error case.
- 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.

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 method 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.
successCallback: Function called when the properties have been successfully retrieved.
options [optional] [nullable]: An object containing the various options for fetching the properties requested.
errorCallback [optional] [nullable]: Function called when an error occurred.

Return value:

unsigned long An identifier used to clear the watch subscription.

Exceptions:

WebAPIException
- with error type TypeMismatchError, if the input parameter is not compatible with the expected type.
- with error type InvalidValuesError, if any of the input parameters contain an invalid value (e.g. the invalid value for options).
- with error type UnknownError in any other error case.
- 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.

removePropertyValueChangeListener

Unsubscribes notifications for property changes.

void removePropertyValueChangeListener(unsigned long listenerId);

Since: 1.0

If a valid listenerId argument is passed that corresponds to a subscription already place, then the watch process MUST immediately terminate and no further callback is invoked. If the listenerId argument does not correspond to a valid subscription, the method should return without any further action.

Parameters:

listenerId: An identifier of the subscription returned by the addPropertyValueChangeListener()/addPropertyValueArrayChangeListener() method.

Exceptions:

WebAPIException
- with error type TypeMismatchError, if the input parameter is not compatible with the expected type.
- with error type InvalidValuesError, if any of the input parameters contain an invalid value.
- 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, we clear it
        tizen.systeminfo.removePropertyValueChangeListener(id);
    }
 }

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

Privilege: http://tizen.org/privilege/led

Parameters:

brightness: The brightness value of LED (0~1)

Exceptions:

WebAPIException
- with error type InvalidValuesError, if any of the input parameters contain an invalid value.
- with error type SecurityError, if the application does not have the privilege to call this method or if the author signature does not match that of the designated application.
- with error type UnknownError, if the method cannot be completed because of an unknown error.

Code example:

 tizen.systeminfo.getPropertyValue("CAMERA_FLASH",
    function (flash) {
        try {
            flash.setBrightness(1);
        } catch (error) {
            console.log("Setting flash brightness failed: " + error.message);
        }
    },
    function (error) {
        console.log("Error, name: " + error.name + ", message: " + error.message);
    }
 );
