Actually I have found the solution to the above problem, well kind of, it
turns out the problem is elsewhere,
I am trying to find the Id of a contact via the phone number and try as
follows but I get an ID of 2324 when it should be 404, anyone any ideas why?
static {
int sdk=new Integer(Build.VERSION.SDK).intValue();
if (sdk>=5) {
try {
Class
clazz=Class.forName("android.provider.ContactsContract$CommonDataKinds$Phone");
CONTENT_URI=(Uri)clazz.getField("CONTENT_URI").get(clazz);
NAME_URI=(String) clazz.getField("DISPLAY_NAME").get(clazz);
ID_URI=(String) clazz.getField("_ID").get(clazz);
NUMBER_URI=(String)clazz.getField("NUMBER").get(clazz);
}
catch (Throwable t) {
Log.e("reflection", "Exception when determining CONTENT_URI", t);
}
}
else {
CONTENT_URI=Contacts.People.CONTENT_URI;
NAME_URI=People.NAME;
ID_URI=People._ID;
NUMBER_URI=People.NUMBER;
}
}
----
public int getContactId(String phoneNumber){
String [] requestedColumns = {
NAME_URI,
ID_URI
};
Cursor contacts = context.getContentResolver().query(
CONTENT_URI,
requestedColumns,
NUMBER_URI + "='" + phoneNumber + "'",
null, null);
Log.d("GETDETAILS", "Count = " + contacts.getCount());
if(contacts.getCount() > 0){
int nameIdx = contacts.getColumnIndex(NAME_URI);
int idIdx = contacts.getColumnIndex(ID_URI);
contacts.moveToFirst();
Log.d("DETAILS", "Name : " + contacts.getString(nameIdx));
Log.d("DETAILS", "Type : " + contacts.getString(idIdx));
return contacts.getInt(idIdx);
}
else
return 0;
}
