Android native contact modification

I'm new to android and i'm working with native contact.
So my app is let user put contact display name and their number for edit/delete.
In case the contact have more that one number.
I tried a lot but still have no luck, the app still doesn't update the number or it crashes.
What I'm going to do as my understanding is:
Find name in contact that matched name user inserted and use that to get contact_id that represent this contact datagroup.
Use contact_id in 1. and the number user input to find ._ID that represent the specific row id.
Do task with ._ID we get from 2.
This is 1. code to get contact_id:
public String getPeopleUniqueID(String name, Context context) {
String s = null;
String selection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" like'%" + name +"%'";
String[] projection = new String[] {ContactsContract.Data.CONTACT_ID};
Cursor c = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection, selection, null, null);
if(c.moveToFirst()) {
s = c.getString(c.getColumnIndex(ContactsContract.Data.CONTACT_ID));
}
c.close();
return s;
}
This is 2. code to get ._ID (num is number user inserted and name is from 1. > the contact_id)
public String checkPhoneNumber(String num, String name, Context context) {
String s = null;
String selection = ContactsContract.CommonDataKinds.Phone.NUMBER + "=?" + " AND "+ContactsContract.Data.CONTACT_ID+ "=?";
String[] projection = new String[] {ContactsContract.Data._ID};
Cursor c = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection, selection, new String[]{u,name}, null);
if(c.moveToFirst()) {
s=c.getString(c.getColumnIndex(ContactsContract.Data._ID));
}
c.close();
if (s==null){
s = "null";
}
return s;
}
To do something like editing (num is _.ID we get from 2. and newnum is new number user want to change into).
public void editNumber(String num , String newnum) {
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI)
.withSelection(Data._ID + "=? AND " +
Data.MIMETYPE + "='" +
CommonDataKinds.Phone.CONTENT_ITEM_TYPE + "'",
new String[]{num})
.withValue(Data.DATA1, newnum)
.build());
try{
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);}
catch (RemoteException e){e.printStackTrace();}catch (OperationApplicationException e) {e.printStackTrace();}
}
And well it crashes when I call editNumber().
Can you help me fix my code and my understanding?
And another question, can I edit/insert group for the contact programatically, like I want to add this contact to family friend or co-worker group (the default group that we can set at contact edit page)?

Use ContactsContract.Contacts.CONTENT_FILTER_URI for searching a contact based on name - to get Id or anything else. The like operator cannot handle all cases which the CONTENT_FILTER_URI does handle - For various languages, special characters etc.
http://developer.android.com/reference/android/provider/ContactsContract.Contacts.html#CONTENT_FILTER_URI
Use following uri to lookup a contact from phone number - you can get person id or anything else :
Uri lookupUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,
Uri.encode(phoneNumber));
In the set query you can also use contactId in the condition
For groups you can use custom mimetypes if the default one does not suit you (which is still very primitive for groups across different account types)

Android SMS show contact name by recipient_ids

The code snippet below returns basic SMS conversation data:
Cursor cursor = activity.getContentResolver().query(Uri.parse( "content://mms-sms/conversations?simple=true"), null, null, null, "normalized_date desc" );
if(cursor.moveToFirst())
String recipient_ids = cursor.getString(3);
My question is that how can I get a phone's contact data given that recipient_ids? In this case I need to retrieve the contact number and contact display_name.
Your help is greatly appreciated. Thanks in advance!

Try this:
public String getContactData(String id){
String number;
Cursor phones = fa.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id, null, null);
if(phones.moveToFirst()) {
number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
return number;
}
Hope it helps!

This is, what's working in my app:
private String getContactNumber(final long recipientId) {
String number = null;
Cursor c = getContentResolver().query(ContentUris
.withAppendedId(Uri.parse("content://mms-sms/canonical-address"), recipientId),
null, null, null, null);
if (c.moveToFirst()) {
number = c.getString(0);
}
c.close();
return number;
}
The contact numbers are saved in some table called canonical-address.
It was kind of buggy a few years ago. Updates on the contact did not propagate through this table properly. But I think that's fine now.
You basically need to parse the (list of) ids into single ids. Then query the database for each of them.
You could use one single query for all ids together, though.

Update display_name of contact Android

This method always return false. I would like update display name of contact...
public int updateDisplayName(long id, String newname) {
Uri contact = ContentUris.withAppendedId(Contacts.CONTENT_URI, id);
ContentValues values = new ContentValues();
values.put(Contacts.DISPLAY_NAME, newname);
return context.getContentResolver().update(contact, values, null, null);
}
Can you help me?
Thanks,
Mateus

That's not surprising, this table is for aggregating information of multiple accounts and most of its data is only manipulated by the Contacts content provider itself.
See the documentation: http://developer.android.com/reference/android/provider/ContactsContract.Contacts.html
You would have to change the raw contact.

LOOKUP_KEY and CONTENT_LOOKUP_URI

I have the following code to get details of a contact.
"data": is the Uri I get back after selecting the contact.
I need to be sure that I will get to the right contact in the future so what should I be saving for future use? Is it "lookupUri" or "lookupKey"?
Cursor c = activity.managedQuery(data, null, null, null, null);
c.moveToFirst();
String lookupKey = c.getString(c.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY ));
c.close();
// Next use that key to access the details of the contact in order to get the name and the photo
// Also, save it for future use.
// It will be used when we fetch the details from the database since the photo itself is not saved.
Uri lookupUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI,lookupKey);
Uri uri = ContactsContract.Contacts.lookupContact(activity.getContentResolver(), deviceDetails.lookupUri);

LookupKey is the unique identifier that you want to store.
FYI; There is a bug in 2.1 where un-synced contacts LookupKey changes when the name is changed.

This works. My example looks up the name; add or remove the fields you want in the projection.
private String getContactNameFromAndroidKey (String key)
{
// Run query
Uri uri = Uri.parse (ContactsContract.Contacts.CONTENT_LOOKUP_URI + "/" + key);
String[] projection = new String[] {
Contacts._ID,
Contacts.DISPLAY_NAME,
};
Cursor cursor = context.getContentResolver().query (
uri,
projection,
null,
null,
null);
if (!cursor.moveToNext()) // move to first (and only) row.
throw new IllegalStateException ("contact no longer exists for key");
String name = cursor.getString(1);
cursor.close();
return name;
}

writing exception to parcel exception while updating contact name in android?

I need to update a column (cached_name) of table callog.calls in sql lite database in android.what I can't figure out is how to use update statement.I am unable to find anything regarding update command using cursor.kindly help.thanks in advance.
//number1 is the phone number against which I need to run update query in db.
//name is the string which I used to insert against number1..
String name=edittext.gettext().tostring();
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(CallLog.Calls.CONTENT_URI,
null, null, null, null);
ContentValues value=new ContentValues();
value.put("CallLog.Calls.CACHED_NAME",name);
cur.moveToFirst();
while(!cur.isLast())
{
String number=cur.getString(cur.getColumnIndex(CallLog.Calls.NUMBER));
if((number.equals(number1)==true)
{
try{
cr.update(CallLog.Calls.CONTENT_URI,value,CallLog.Calls.CACHED_NAME+"=?",null);
}
catch(Exception e)
{
e.printStackTrace();
System.out.println(e.getStackTrace());
}
}//if
cur.moveToNext();
}//while

Basically, the only line you actually need is the update :
String name = edittext.getText().toString();
ContentResolver cr = getContentResolver();
ContentValues value = new ContentValues();
// Note that there is no "" here. The value is a constant
value.put(CallLog.Calls.CACHED_NAME, name);
cr.update(CallLog.Calls.CONTENT_URI, values, CallLog.Calls.NUMBER+"=?",
new String[] { number1 });
This is equivalent to this raw SQL query:
UPDATE call_log SET cached_name = name WHERE number = number1;
There is no need for iterating over all the calls, that's what the where clause is for.
Also,
while(!cur.isLast())
prevents you from actually reading the last matching value. Don't do that. Use
while (cur.moveToNext())
when you need to iterate over a cursor (which you don't, here)
I strongly suggest you take a look at how cursors work, as well as how sql works.
(Also, out of curiosity, why do you need to modify the callLog table?)
