I want to delete all contacts from my android phone that starts with a "AAA" or that contains "AAA" . Here's what I tried:
private void deleteContact(String name) {
ContentResolver cr = getContentResolver();
String where = ContactsContract.Data.DISPLAY_NAME + " = ? ";
String[] params = new String[] {"AAAA"};
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
ops.add(ContentProviderOperation.newDelete(ContactsContract.RawContacts.CONTENT_URI)
.withSelection(where, params)
.build());
Log.e(",,,,",String.valueOf(ops.get(0)));
try {
cr.applyBatch(ContactsContract.AUTHORITY, ops);
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OperationApplicationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Toast.makeText(NativeContentProvider.this, "Deleted the contact with name '" + name +"'", Toast.LENGTH_SHORT).show();
}
but failed. Please give me some idea so I can proceed further in my project.
Maybe this will get you on the right track:
ContentResolver mContentResolver = getContentResolver();
private int deleteContactsLike(String name) {
return mContentResolver.delete(
ContactsContract.RawContacts.CONTENT_URI,
ContactsContract.Contacts.DISPLAY_NAME
+ " like ?",
new String[] { name + '%'});

I'm trying to use this code to allow a user edit a contact's name and number. I get no errors and when I print nameofcontact and numberofcontact in my log it shows me the latest changes I've made to the name and number of the contact.
But it's not saving to my contacts database. Any ideas what's wrong?
public void editButton(View view) {
// the text in the 'nameofcontact' edittext box, can be modified by the user
contactname = nameofcontact.getText().toString();
// the text in the 'numberofcontact' edittext box, can be modified by the user
contactnumber = numberofcontact.getText().toString();
ContentResolver cr = getContentResolver();
String where = ContactsContract.Data.DISPLAY_NAME + " = ? AND " +
ContactsContract.Data.MIMETYPE + " = ? AND " +
String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE) + " = ? ";
String[] params = new String[] {contactname,
ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,
String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_HOME)};
Cursor phoneCur = getContentResolver().query(ContactsContract.Data.CONTENT_URI, null, where, params, null);
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
// if ( (null == phoneCur) ) {
// createContact(name, phone);
// } else
{
ops.add(ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI)
.withSelection(where, params)
.withValue(ContactsContract.CommonDataKinds.Phone.DATA, contactnumber)
.build());
}
phoneCur.close();
try {
cr.applyBatch(ContactsContract.AUTHORITY, ops);
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OperationApplicationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println (contactname);
System.out.println (contactnumber);
Toast.makeText(this, "Updated", Toast.LENGTH_SHORT).show();

Please check you add below permission in your manifeast or not
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
and you can use this method it works for me.
public boolean updateContact(String name, String number, String ContactId) {
boolean success = true;
String phnumexp = "^[0-9]*$";
try {
name = name.trim();
number = number.trim();
if (name.equals("") && number.equals("")) {
success = false;
} else if ((!number.equals("")) && (!match(number, phnumexp))) {
success = false;
} else {
ContentResolver contentResolver = SwipableHomeActivity.this
.getContentResolver();
String where = Data.CONTACT_ID + " = ? AND "
+ Data.MIMETYPE + " = ?";
String[] nameParams = new String[]{
ContactId,
StructuredName.CONTENT_ITEM_TYPE};
String[] numberParams = new String[]{
ContactId,
Phone.CONTENT_ITEM_TYPE};
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
if (!name.equals("")) {
ops.add(ContentProviderOperation
.newUpdate(
Data.CONTENT_URI)
.withSelection(where, nameParams)
.withValue(StructuredName.DISPLAY_NAME, name)
.build());
}
if (!number.equals("")) {
ops.add(ContentProviderOperation
.newUpdate(
Data.CONTENT_URI)
.withSelection(where, numberParams)
.withValue(Phone.NUMBER, number).build());
}
contentResolver.applyBatch(ContactsContract.AUTHORITY, ops);
}
} catch (Exception e) {
e.printStackTrace();
success = false;
}
return success;
}
I write an Update method to update contacts but after i run this on my phone nothing happen
and no contact get update why?
this is my method :
public Boolean UpdateContacts(ArrayList<ContactInfo> encryptedContactsInfoList) {
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
ContentResolver cr = null;
for (ContactInfo contactInfo : encryptedContactsInfoList) {
try {
String contactId = contactInfo.getContactID();
String contactName = contactInfo.getContactName();
String contactNumber = contactInfo.getContactNumber();
ops.add(ContentProviderOperation
.newUpdate(Data.CONTENT_URI)
.withSelection(
ContactsContract.CommonDataKinds.Phone._ID
+ " = ?", new String[] { contactId })
.withValue(ContactsContract.Data.DISPLAY_NAME,
"asdffgh").build());
cr.applyBatch(ContactsContract.AUTHORITY, ops);
} catch (Exception e) {
Log.d("exception", e.getMessage());
}
}
return true;
}
this is ops after executing the code:
[{"mSelection":"_id \u003d ?","mSelectionArgs":["2302"],"mUri":{"authority":
{"decoded":"com.android.contacts","encoded":"com.android.contacts"},"fragment":{},"path":
{"decoded":"NOT CACHED","encoded":"/data"},"query":{},"scheme":"content","uriString":"NOT
CACHED","host":"NOT CACHED","port":-2},"mValues":{"mValues":
{"display_name":"asdffgh"}},"mType":2,"mYieldAllowed":false}]
any help really appreciate,
best regards.
You get nothing because your ContentResolver is null, so you get an exception in every iteration.
Your app does not crash because you have catch (Exception e) that catches every exception.
try with:
ContentResolver cr = getContentResolver();
also, the applyBatch call should be after the for loop, otherwise you are procesing many times every item, and change ContactsContract.CommonDataKinds.Phone._ID to ContactsContract.Data._ID
try {
for (ContactInfo contactInfo : encryptedContactsInfoList) {
String contactId = contactInfo.getContactID();
String contactName = contactInfo.getContactName();
String contactNumber = contactInfo.getContactNumber();
ops.add(ContentProviderOperation
.newUpdate(Data.CONTENT_URI)
.withSelection(
ContactsContract.Data._ID
+ " = ?", new String[] { contactId })
.withValue(ContactsContract.Data.DISPLAY_NAME,
"asdffgh").build());
}
cr.applyBatch(ContactsContract.AUTHORITY, ops);
} catch (Exception e) {
Log.d("exception", e.getMessage());

I have some issues when updating phone number for contacts of different phone type. I need to add prefix xxx with all the numbers. For example: "Paul" have Mobile: 42342397908, Home: 3453459534, Work: 4345436533, Other: 3253454354, Other: 3465465464, Mobile: 34564654654. The update is working but when it saves it is like this. Mobile: xxx42342397908, Home: xxx3453459534, Work: xxx4345436533, Other: xx3253454354, Other: xx3253454354, Mobile: xxx42342397908. It overrides the one which have same phone type with the same phone number. please see below my update function and help me.
private void updateContact(String name, String phone,String id, String type) {
ContentResolver cr = getContentResolver();

I have this code
public void updateContact (String contactId, String newNumber) {ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
String selectPhone = Data.CONTACT_ID + "=? AND " + Data.MIMETYPE + "='" +
Phone.CONTENT_ITEM_TYPE + "'";
String[] phoneArgs = new String[]{contactId};
ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI)
.withSelection(selectPhone, phoneArgs)
.withValue(Phone.NUMBER, newNumber)
.build());
try { getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OperationApplicationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
which i took from here How to update contact number using Android and changed it in order to pass through all my contacts and add to each one of them a prefix of my own.
I run through all contacts and i provide with this
String id = phones.getString(phones.getColumnIndex(ContactsContract.Contacts._ID));
the Contact's id to the function above. But some contacts Especially the ones that have multiple numbers and some that have only one number, do not change to get the new prefix even though the given id is correct?! .
Do i miss something here i don't know what to change. I think it may be the mime type but i can imagine that someone may not used the Android preinstalled types for phones and used a custom type.
I do not get any errors. Thanks everyone for your time!!!
I finally changed my code to work properly, i was passing the contact ID but i needed the phone id ...here is the correct code.
public void updateContact (String contactId, String newNumber) {
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
String selectPhone = Data._ID + "=? AND " + Data.MIMETYPE + "='" +
Phone.CONTENT_ITEM_TYPE + "'";
String[] phoneArgs = new String[]{contactId};
ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI)
.withSelection(selectPhone, phoneArgs)
.withValue(Phone.NUMBER, newNumber)
.build());
try {
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OperationApplicationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Do not forget to set the appropriate permissions on android manifest (write contacts)
i am working on the application which retrieve all the android contacts and also can delete and update contacts.everything working fine problem is when contact does not have email address then i can not update it using my application (can not add email address from my update contact page). i have written used code below. thanks in advance.
private void updateEmaill(String id, String email) {
ContentResolver cr = getContentResolver();
String where = ContactsContract.Data.RAW_CONTACT_ID + " = ? AND "
+ ContactsContract.Data.MIMETYPE + " = ?";
String[] params = new String[] { id,
ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE };
Cursor phoneCur = managedQuery(ContactsContract.Data.CONTENT_URI, null,
where, params, null);
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
if ((null == phoneCur)) {
System.out.println("we have got null value from the cursor");
} else {
System.out.println("phone cursor count" + phoneCur.getCount());
ops.add(ContentProviderOperation
.newUpdate(ContactsContract.Data.CONTENT_URI)
.withSelection(where, params)
.withValue(ContactsContract.CommonDataKinds.Email.ADDRESS,
email).build());
}
phoneCur.close();
try {
cr.applyBatch(ContactsContract.AUTHORITY, ops);
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (OperationApplicationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
newUpdate() has been known to work only if a given field exists already.
As a workaround, here's one simple logic you can use:
-check if email exists for contacts
-if it does call update
-if it doesn't save all the fields of this contact in some variables and delete the contact
-use newInsert() to create a new contact with the saved fields from old contact and also the email that you need to add.
