Please note that as of October 24, 2014, the Nokia Developer Wiki will no longer be accepting user contributions, including new entries, edits and comments, as we begin transitioning to our new home, in the Windows Phone Development Wiki. We plan to move over the majority of the existing entries. Thanks for all your past and future contributions.
PIM API on Java ME
Many devices, especially phones, have the ability to maintain lists of phone numbers and names. Some devices also store addresses, e-mails, events, to-do lists, and other personal information. This PIM data is stored in PIM databases. Most devices will have built-in applications that manage the PIM data. Until recently, there was no direct way of accessing this information from your MIDP application. A device vendor may now expose access to its PIM databases through the PIM Optional Package, specified in JSR 75.
Determining If PIM Optional Package Is Available
It is needed to check weathere this package is available or not. We can do it with following code.
String currentVersion = System.getProperty("microedition.pim.version " )
You should also use the returned version to make sure your code is version compatible. At this time, however, only version “1.0” is available. The call will return null if the optional package is not available.
Obtaining the Singleton PIM Instance
There is PIM class which we need to use. It is a abstract class so we cannot create object of it so we need to use following static method to get the instant of PIM.
public static PIM getInstance()
Procedure for Opening the PIM Lists
We can access the PIM lists once we have the singleton instance. A PIM list can be obtained using one of these methods.
public PIMList openPIMList(char pimListType, int mode) throws PIMException
public PIMList openPIMList(int pimListType, int mode, String name) throws PIMException
possible value for pimListType : PIM.CONTACT_LIST, PIM.EVENT_LIST, or PIM.TODO_LIST.
possible value for mode :PIM.READ_ONLY, PIM.READ_WRITE, or PIM.WRITE_ONLY
Functions Used Reading Field Value
The following functions are used to read filed values.
