These can be set by means of the attr command, displayed with the displayattr command, and deleted by the deleteattr command. There are global attributes that are used by all devices and local attributes that apply to individual device classes only. See the documentation of the attr command for examples. Be careful not to overwrite additional global attributes previously defined by yourself or a device.
The getCurrentPosition method takes one, two or three arguments. When called, it must immediately return and then asynchronously attempt to obtain the current location of the device. If the attempt is successful, the successCallback must be invoked i.
If the attempt fails, the errorCallback must be invoked with a new PositionError object, reflecting the reason for the failure. The implementation of the getCurrentPosition method must execute the following set of steps: If a cached Position object, whose age is no greater than the value of the maximumAge variable, is available, invoke the successCallback with the cached Position object as a parameter and exit this set of steps.
Start a location acquisition operation e. Start a timer that will fire after the number of milliseconds denoted by the value of the timeout variable. When the timer fires, cancel any ongoing location acquisition operations associated with this instance of the steps, invoke the errorCallback if present with a new PositionError object whose code attribute is set to TIMEOUT, and exit this set of steps.
If the operation completes successfully before the timeout expires, cancel the pending timer, invoke the successCallback with a new Position object that reflects the result of the acquisition operation and exit this set of steps. The watchPosition method takes one, two or three arguments.
When called, it must immediately return a long value that uniquely identifies a watch operation and then asynchronously start the watch operation. This operation must first attempt to obtain the current location of the device.
The watch operation then must continue to monitor the position of the device and invoke the appropriate callback every time this position changes. The watch operation must continue until the clearWatch method is called with the corresponding identifier.
The implementation of the watch process must execute the following set of steps: If a cached Position object, whose age is no greater than the value of the maximumAge variable, is available, invoke the successCallback with the cached Position object as a parameter.
Register to receive system events that indicate that the position of the device may have changed e.
Run the following acquisition steps: If the timer is not already running, start a timer that will fire after the number of milliseconds denoted by the value of the timeout variable. If the location acquisition operation successfully yields a new position before the timeout expires, perform the following two steps: Cancel the pending timer.
Note that the timer must be restarted once this algorithm jumps back to the beginning of the acquisition steps. If the new position differs significantly from the previous position, invoke the successCallback with a new Position object that reflects the result of the acquisition operation.
This step may be subject to callback rate limitation see below. Wait for a system event to be received. When such an event is received jump to the acquisition steps above. The definition of what constitutes a significant difference is left to the implementation.
Furthermore, in steps 5. For both getCurrentPosition and watchPosition, the implementation must never invoke the successCallback without having first obtained permission from the user to share location.
Furthermore, the implementation should always obtain the user's permission to share location before executing any of the getCurrentPosition or watchPosition steps described above. If the user grants permission, the appropriate callback must be invoked as described above. The time that is spent obtaining the user permission must not be included in the period covered by the timeout attribute of the PositionOptions parameter.
The timeout attribute must only apply to the location acquisition operation. The method takes one argument. When called, it must first check the value of the given watchId argument.
If this value does not correspond to any previously started watch process, then the method must return immediately without taking any further action.When trying to insert content values via ContentProvider on LG G2 in timberdesignmag.comme() the application crashes after rotation change.
