Use Cases

To record the history of user activity with the device, particularly with communication services (Phone Calls, Messages, Social Networks, etc.)

Consumers

  • Comms Log Application (Global for the user and per-contact)

Producers

  • Dialer, SMS, e-mail, Facebook, Twitter, ...

WebIDL

interface LogManager : EventTarget  {
    DOMRequest put(LogEntry entry);
    DOMRequest delete(DOMString entryId);
    DOMRequest clear(LogClearOptions coptions);
    // Entries are always returned ordered by timestamp
    DOMRequest find(LogFindOptions options);
        
   attribute Function onentryadded;
 };

interface LogIterator {
  DOMRequest next(optional unsigned short n);
  attribute boolean hasMore;
  attribute unsigned long position;
};

dictionary LogFindOptions {
   attribute unsigned long maxRecords;
   attribute DOMString contactId;
   attribute Date from;
   attribute Date to;
   attribute DOMString service;
};

interface LogEntryProperties {
   attribute DOMString type;           // possible values: ['incoming', 'outgoing'']
   attribute DOMString status;        // [missed, new]
   attribute DOMString[] contactId; // ContactId
   attribute DOMString[] tel;           // Tel number if not in contacts
   attribute DOMString objectId;    // Object id (for example SMS message on the SMS database)
   attribute DOMString service;      // oneOf ['SMS', 'Telephony', 'Facebook', 'Twitter'] 
   attribute DOMString title;             
   attribute DOMString description;
   attribute any extra;                                // Any extra data to be used by applications
};

[Constructor(LogEntryProperties properties)]
interface LogEntry : LogEntryProperties {
   readonly attribute DOMString id;
   readonly attribute DOMTimestamp timestamp;                  // When happened
};

Examples

Get latest global 20 log entries (ordered by timestamp, newest to oldest)

var filter = {maxNumber: 20};
var req = navigator.mozLog.find(filter);
req.onsuccess = function(e) {
  var iterator = e.target.result;
  
  var req2 = iterator.next(10);
    req2.onsuccess = function(e) {
      var entries = e.target.result;
      if(iterator.hasMore) {
        iterator.next(10);
      }
  }
}
