问题
I am working on a project in which I want to detect the changes in the Contacts. So I have created Account with Account manager and trying to find the changes in the contact list using DIRTY flag. But the DIRTY flag not getting set for my app account_type when contact updated. however DIRTY flag of another account_type(com.google) is getting set. Help me
This is how I am inserting contacts with my account and account_type.
public static void addContact(Context context,MyContact contact){
ContentResolver resolver = context.getContentResolver();
boolean mHasAccount = isAlreadyRegistered(resolver, contact.Id);
if(mHasAccount){
Log.d("Contact already","there");
} else {
Log.d("new Contact","Adding");
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
// insert account name and account type
ops.add(ContentProviderOperation
.newInsert(addCallerIsSyncAdapterParameter(ContactsContract.RawContacts.CONTENT_URI, true))
.withValue(ContactsContract.RawContacts.ACCOUNT_NAME, constants.ACCOUNT_NAME)
.withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, constants.ACCOUNT_TYPE)
.withValue(ContactsContract.RawContacts.AGGREGATION_MODE,
ContactsContract.RawContacts.AGGREGATION_MODE_DEFAULT)
.build());
// insert contact number
ops.add(ContentProviderOperation
.newInsert(addCallerIsSyncAdapterParameter(ContactsContract.Data.CONTENT_URI, true))
.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
.withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE)
.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, contact.number)
.build());
// insert contact name
ops.add(ContentProviderOperation
.newInsert(addCallerIsSyncAdapterParameter(ContactsContract.Data.CONTENT_URI, true))
.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
.withValue(ContactsContract.Data.MIMETYPE,
ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE)
.withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME, contact.name)
.build());
// insert mime-type data
ops.add(ContentProviderOperation
.newInsert(addCallerIsSyncAdapterParameter(ContactsContract.Data.CONTENT_URI, true))
.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
.withValue(ContactsContract.Data.MIMETYPE, MIMETYPE)
.withValue(ContactsContract.Data.DATA1, 12345)
.withValue(ContactsContract.Data.DATA2, "user")
.withValue(ContactsContract.Data.DATA3, "MyData")
.build());
try {
resolver.applyBatch(ContactsContract.AUTHORITY, ops);
} catch (Exception e) {
e.printStackTrace();
}
}
}
Code to check the changes in contact list
private void updateServer(){
Log.d("Server", "updating");
Cursor cursor = mContentResolver.query(ContactsContract.RawContacts.CONTENT_URI,
new String[]{ContactsContract.RawContacts.DIRTY, ContactsContract.RawContacts.CONTACT_ID,ContactsContract.RawContacts.ACCOUNT_TYPE},
ContactsContract.RawContacts.DIRTY+"=? ",
new String[]{String.valueOf(1)},
null);
if (cursor != null && cursor.getCount() >0)
{
cursor.moveToFirst();
while(!cursor.isAfterLast()){
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.CONTACT_ID));
String dirty = cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.DIRTY));
String type = cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.ACCOUNT_TYPE));
if(id!=null && dirty!=null&& type!=null){
Log.d("Upadte Dirty",dirty);
Log.d("Update ACCountid",id);
Log.d("Update type", type);
Cursor cur = mContentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME},
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?",
new String[]{String.valueOf(id)},
null);
if(cur!=null && cur.getCount()>0) {
cur.moveToFirst();
while(!cur.isAfterLast()){
String name = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String number = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.d("Update Name", name);
Log.d("Update Number", number);
/* ContactsManager.updateContact(getContext(), id, name, number);
CV.clear();
CV.put(DBconstants.TableConstants.PHONE_NUMBER, number);
CV.put(DBconstants.TableConstants.C_CONTACT_NAME, name);
DB.updateInformation(DB, DBconstants.TableConstants.TABLE_CONTACTS, CV, DBconstants.TableConstants.C_ID, id);
CV.clear();
*/ cur.moveToNext();
}
cur.close();
}else{
Log.d("Serverupdate", "nullinvalues");
}
}else{
Log.d("Serverupdate", "nullvalues");
}
cursor.moveToNext();
}
cursor.close();
}else {
Log.d("Serverupdate", "nullcursor");
}
