Performance of update existing contact in Android so slow

Performance of update existing contact in Android so slow - android

i have a problem in update existing contact in Android. My code execute about 400 contact but it take me about 20s to update it. Here is my code.
public class Contact {
private long contactId;
private String phoneNumber;
private int phoneType;
}
Then i try to update each contact filter by ID and Type:
ArrayList list = arrayLists[0];
for (int i = 0; i < list.size(); i++) {
Contact contact = list.get(i);
long contactID = contact.getContactId();
String newPhoneNumber = contact.getPhoneNumber();
int phoneType = contact.getPhoneType();
updateContact(contactID, newPhoneNumber, phoneType);
}
Here is my updateContact funtion:
private void updateContact(long contactID, String newPhoneNumber, int phoneType) {
ContentResolver cr = getContentResolver();
String where = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND " + ContactsContract.CommonDataKinds.Phone.TYPE + " = ?";
String[] whereParams = new String[]{contactID + "", phoneType + ""};
ContentValues contentValues = new ContentValues();
contentValues.put(ContactsContract.CommonDataKinds.Phone.NUMBER, newPhoneNumber);
Uri dataUri = ContactsContract.Data.CONTENT_URI;
cr.update(dataUri, contentValues, where, whereParams);
}
I tried other method to update contact but it also take same time ( about 20s for 400 contact)
private void updateContact(long contactID, String newPhoneNumber, int phoneType) {
ContentResolver cr = getContentResolver();
String where = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND " +
ContactsContract.CommonDataKinds.Phone.TYPE + " = ?";
String[] params = new String[]{contactID + "", phoneType + ""};
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
.withSelection(where, params)
.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, newPhoneNumber)
.build());
try {
cr.applyBatch(ContactsContract.AUTHORITY, ops);
} catch (RemoteException e) {
e.printStackTrace();
} catch (OperationApplicationException e) {
e.printStackTrace();
}
}
What should i do, how can i improve the performance of update job. I expert it can update 400 contact in 3-5s

Contact Ids are missing when querying to raw contacts table according to account name

I am unable to get all contact ids from the RawContacts table

//I am facing problem in this method only below code is just for understanding.
}
}
Contact ids are passed to the below method with account name to get the contact details from respective id but contact ids are less compare to the log //Utils.Log("Raw Size", " " + rawCursorCount).

please help me to solve this case or suggest any other ways to get the contact_ids . Thanks in Advance.

The problem is that you are loosing the first contact you fetch from the db.
The statement rawCursor.moveToFirst(); positions the cursor on the first available result record. The, when you want to iterate over the results, you call rawCursor.moveToNext() inside your loop. The loop condition is executed before it's body, so, you end up moving the cursor to the second row, loosing the first record.
You can fix this by getting rid of rawCursor.moveToFirst().

Android fetch all contact list (name, email, phone) takes more then a minute for about 700 contacts

Is there any way to shorten this time?
I'm running with the cursor and takes the name, phone numbers and emails
if I remove the phone numbers query from the query loop it ends in 3 seconds
any idea how can I improve that query?
Maybe I'm doing something wrong in my query?
(Obviously I'm doing it async but still... it's a very long time that a user can't wait)
Hope someone can share his thoughts about this
this is my code
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
AddressBookEntity adr = new AddressBookEntity();
String id = cur.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
adr.fullName = name;
Cursor emailCur = cr
.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = ?", new String[] { id },
null);
while (emailCur.moveToNext()) {
// This would allow you get several email addresses
// if the email addresses were stored in an array
String email = emailCur
.getString(emailCur
.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
if (!Utils.IsNullOrEmptyString(email)) {
adr.email = email;
}
}
emailCur.close();
if (Integer
.parseInt(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?",
new String[] { id }, null);
int phoneIndex = 0;
while (pCur.moveToNext()) {
String number = pCur.getString(pCur
.getColumnIndex(Phone.NUMBER));
String country = Utils.GetCountryFromNumber(
number, app);
number = Utils.GetFullPhoneNumber(number, app);
if (phoneIndex == 0) {
if (!Utils.IsNullOrEmptyString(number)) {
adr.contactAdressBookId = id;
adr.phoneNumber = number;
adr.userInsertedId = app.userCred.userId;
adr.country = country;
myContacts.add(adr);
}
} else {
if (!Utils.IsNullOrEmptyString(number)) {
AddressBookEntity adrMore = new AddressBookEntity();
adrMore.fullName = adrMore.fullName;
adrMore.country = adrMore.country;
adrMore.email = adrMore.email;
adrMore.phoneNumber = number;
adrMore.contactAdressBookId = id;
adrMore.country = country;
myContacts.add(adrMore);
}
}
}
pCur.close();
}
}
cur.close();

with the following code for 59 contacts i got the following results on the emulator:
D ╔══════ query execution stats ═══════
D ║ got 59 contacts
D ║ query took 0.012 s (12 ms)
D ╚════════════════════════════════════
ok, that was the best time, but the average is 25-35 ms (for 59 contacts), add the following code in some onClick callback and run in several times in order to get the average time, in your case you should get 30 * 700 / 59 = ~300-400 ms, not 3 seconds, let alone one minute ;)

You retrieve all columns in your query:
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
This makes the data processing much slower. If you define an array of columns which you really need to retrieve, it will be much faster.

ohk u can take contactID from this cursor or your code now this is my method which will give u contact photo just pass contact ID in it
public InputStream openPhoto(long contactId) {
Uri contactUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId);
Uri photoUri = Uri.withAppendedPath(contactUri, Contacts.Photo.CONTENT_DIRECTORY);
Cursor cursor = getContentResolver().query(photoUri,
new String[] {Contacts.Photo.PHOTO}, null, null, null);
if (cursor == null) {
return null;
}
try {
if (cursor.moveToFirst()) {
byte[] data = cursor.getBlob(0);
if (data != null) {
return new ByteArrayInputStream(data);
}
}
} finally {
cursor.close();
}
return null;
}
Hope this will help u Best of luck dude

you should use content provider of contact

How to get all contacts first name, last name, email, phone number, etc without duplicates

I am trying to get details of all the contacts available in phone contacts using below code. But facing small issue of duplicate values.
EDITED
ACTUAL CODE STARTS :-
private String refreshData() {
String emaildata = "";
try {
ContentResolver cr = getBaseContext().getContentResolver();
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP
+ " = '" + ("1") + "'";
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
Cursor cur = cr
.query(ContactsContract.Contacts.CONTENT_URI,
null,
selection
+ " AND "
+ ContactsContract.Contacts.HAS_PHONE_NUMBER
+ "=1", null, sortOrder);
if (cur.getCount() > 0) {
Log.i("Content provider", "Reading contact emails");
while (cur.moveToNext()) {
mContactSet.add(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID)));
}
} else {
emaildata += "Data not found.";
}
cur.close();
Log.i(TAG, "Total contacts = " + mContactSet.size());
Iterator<String> iterator = mContactSet.iterator();
while (iterator.hasNext()) {
String contactId = iterator.next();
Log.i(TAG, "ID ==> " + contactId);
// Create query to use CommonDataKinds classes to fetch
// emails
Cursor emails = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null, ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = " + contactId, null, null);
// Name
String whereName = ContactsContract.Data.MIMETYPE
+ " = ? AND "
+ ContactsContract.CommonDataKinds.StructuredName.CONTACT_ID
+ " = ?";
String[] whereNameParams = new String[] {
ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE,
contactId };
Cursor nameCur = cr
.query(ContactsContract.Data.CONTENT_URI,
null,
whereName,
whereNameParams,
ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME);
while (nameCur.moveToNext()) {
String given = nameCur
.getString(nameCur
.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME));
String family = nameCur
.getString(nameCur
.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME));
String display = nameCur
.getString(nameCur
.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME));
Log.i(TAG, "First Name ==> " + given);
Log.i(TAG, "Last Name ==> " + family);
Log.i(TAG, "Display ==> " + display);
}
nameCur.close();
}
} catch (Exception e) {
emaildata += "Exception : " + e + "";
}
return emaildata;
}
Modified the query and get some better results but still the issue is same for some of the contacts and getting repeat values.
UPDATE :- I have used HashSet to get unique contact id and which I successfully get as well, but when I am getting the names from contact id I am getting the same value for 2-3 times for some of the contacts. I am very much confused that how this is possible that same contact is stored 2-3 times with same id?
DO I NEED TO USE HASHSET FOR FIRST NAME, LAST NAME, PHONE NUMBER, EMAIL, ETC? IS THERE ANY OTHER WAY?

This is the complete solution

How to use?
ArrayList<HashMap<String, Object>> contactList = getContacts();
System.out.println("Contact List : " +contactList);
Output:
[
{
phone=992-561-1618;848-807-4440;,
contactId=1,
photo=android.graphics.Bitmap#44f40aa0,
address=Zalavadia Strret
Manavadar, Gujarat 362630
India,
email=birajzalavadia#gmail.com;biraj#tasolglobal.com;,
name=Biraj Zalavadia
},
{
phone=992-511-1418;842-827-4450;,
contactId=2,
photo=android.graphics.Bitmap#44f40aa0,
address=Makadiya Strret
Junagadh, Gujarat 364890
India,
email=niles#gmail.com;niles#tasolglobal.com;,

NOTE:
You will get phone and email semicolon(;) separated if its more than one.

Delete a single phone type number from a contact

When a one of the contact have multiple numbers, for example:
Display name: GuessWho TYPE = home Number = homeNumber
TYPE = mobile Number = mobileNumber TYPE = other
Number = otherNumber ...
in conclusion ... one from those.
How I can remove a TYPE with number from this contact ( let's say "mobile" )? I have to update it using the userID acquired from the previous query, or how?
I just need to delete a single TYPE with number, other field of the contact must remain intact.
I am using this piece of code for obtaining contact :
int indexName = c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
int indexNumber = c
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
int indexType = c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE);
int indexID = c.getColumnIndex(ContactsContract.CommonDataKinds.Phone._ID);
String name = c.getString(indexName);
String number = c.getString(indexNumber);
String type = c.getString(indexType);
String typeStored = (String) Phone.getTypeLabel(mContext.getResources(), Integer.parseInt(type), "");
Log.i("TYPE READED : ", typeStored);
String id = c.getString(indexID);
where c is the cursor of the query.

Each number from same contact has it's own ID. You should use it for deleting. But you also need contact ID. You can get it using this line of code:
contactID = cursor.getInt(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
Then you delete the number using following code:
Cursor cur = contentResolver.query(RawContacts.CONTENT_URI,
new String[]{RawContacts._ID},
RawContacts.CONTACT_ID + "=?",
new String[] {contactID.toString()}, null);
int rowId=0;;
if(cur.moveToFirst()){
rowId = cur.getInt(cur.getColumnIndex(RawContacts._ID));
}
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
String selectPhone = Data.RAW_CONTACT_ID + " = ? AND " +
Data.MIMETYPE + " = ? AND " +
Phone._ID + " = ?";
String[] phoneArgs = new String[] { Integer.toString(rowId),
Phone.CONTENT_ITEM_TYPE,
ID.toString()};
ops.add(ContentProviderOperation.newDelete(Data.CONTENT_URI)
.withSelection(selectPhone, phoneArgs).build());
try {
contentResolver.applyBatch(ContactsContract.AUTHORITY, ops);
} catch (RemoteException e) {
e.printStackTrace();
} catch (OperationApplicationException e) {
e.printStackTrace();
}

The code to delete is a little long, the below does what it should with less lines of code
public static void deleteContact(ContentResolver contactHelper, String number) {
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
String[] args = new String[] { String.valueOf(getContactID(contactHelper, number)) };
ops.add(ContentProviderOperation.newDelete(RawContacts.CONTENT_URI).withSelection(RawContacts.CONTACT_ID + "=?", args).build());
try {
contactHelper.applyBatch(ContactsContract.AUTHORITY, ops);
} catch (RemoteException e) {
e.printStackTrace();
} catch (OperationApplicationException e) {
e.printStackTrace();
}
}
