Interface DeviceManager

public interface DeviceManager

Interface that defines access to device-specific functionality, such as camera and GPS. Java code should make use of this interface via DeviceManagerFactory.getInstance(). Internally, the DeviceDataControl also makes use of this interface to fulfill requests for device side functionality.

Parameters:

aContact - - a previously-constructed Contact object

Returns:

a Contact object. Note that you should always use the returned Contact object in subsequent operations, because this object will have the requisite primary key

removeContact

void removeContact(Contact aContact)

Parameters:

aContact - - the modified Contact object to persist in the device's address book.

Returns:

- the modified Contact object

findContacts

Contact[] findContacts(java.lang.String contactFields,
                       java.lang.String filter,
                       boolean multiple)

Enables retrieval of one or more Contact objects matching the specified criteria. See PhoneGap documentation for more details: http://docs.phonegap.com/en/1.0.0/phonegap_contacts_contacts.md.html#contacts.find

Parameters:

contactFields - - comma-delimited list of field names to match on, e.g. "id,displayName,name,nickname,phoneNumbers,emails,addresses,ims,organizations birthday,note,photos,categories,urls". Note that categories is always null in the return value on iOS and Android devices.

filter - - search criteria. Note that the search criteria is matched against all fields specified in contactFields, so if you specify "John", a Contact object will be matched if any of the fields specified in contactFields (e.g. name OR address OR phoneNumber) contains the filter

Returns:

an array of Contact objects. Note that each Contact object will ONLY contain the fields you specified in the contactFields parameter; all others will be empty/null. See PhoneGap documentation for more details.

sendEmail

void sendEmail(java.lang.String to,
               java.lang.String cc,
               java.lang.String subject,

mimeTypes - - list of MIME types, specified in the same order as the list of attachments. Specify null to let the system automatically determine MIME types for all attachments, or leave blanks in the comma-separated list to indicate the system should determine the MIME type only for those selected attachments. Example: attachments = "www/foo.txt,www/bar.png", mimetypes = "text/plain," means the first attachment is of type text/plain, but the system should automatically determine the MIME type for the second one.
