How to retrieve a single contact

how can I retrieve a single contact and some associated data (e.g. emails, phonenumbers, addresses...) by its id/lookupkey?
This is the code I use to add contacts (actually its from the internet and is working for me).
// Asking the Contact provider to create a new contact
try {
result = this.context.getContentResolver().applyBatch(
ContactsContract.AUTHORITY, ops);
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(this.context, "Exception: " + e.getMessage(),
Toast.LENGTH_SHORT).show();
}
Uri myContactUri = result[0].uri;
int lastSlash = myContactUri.toString().lastIndexOf("/");
int length = myContactUri.toString().length();
int contactID = Integer.parseInt((String) myContactUri.toString()
.subSequence(lastSlash + 1, length));
return contactID;
Now I want to fetch this new contact. How do I do it? All I came up with is this:
ContentResolver content = context.getContentResolver();
String[] projection = { Data.LOOKUP_KEY, Data.MIMETYPE,
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Email.ADDRESS };
// Defines the selection clause
String selection = Data.LOOKUP_KEY + " = ?";
// Defines the sort order
String sortOrder = Data.LOOKUP_KEY;
String[] args = {"2400"};
Cursor cursor = content.query(Data.CONTENT_URI, projection, selection,
args, sortOrder);
When I remove the selection I get all contacts+all their data. So I looked up the key 2400 in my case and wanted to fetch this contact by its lookupkey. Well, does not work. cursor.getCount() return 0.
Any ideas?

My solution now is to use to following:
String[] projection = { Data.MIMETYPE,
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Email.ADDRESS };
// Defines the selection clause
String selection = ContactsContract.Data.RAW_CONTACT_ID + "=?";
// Defines the sort order
String sortOrder = Data.LOOKUP_KEY;
String[] args = { id+"" };
Cursor cursor = content.query(Data.CONTENT_URI, projection, selection,
args, sortOrder);
Sort order doesnt matter, but I use the RAW_CONTACT_ID, which works well!

Get the company name of contact in android?

Hi i am doing a app on contact app i got the contact id and the Display name using the below code now what i want is the company name alone with the contact id and the display name.how can i get the Company name?
private void populateContactList() {
// Build adapter with contact entries
Cursor cursor = getContacts();
fields = new String[] { ContactsContract.Data.DISPLAY_NAME,
ContactsContract.Contacts._ID};
contactqueryAdaptor = new Contactquery_adaptor(this, R.layout.row,
cursor, fields, new int[] { R.id.applese });
}
//getContacts()
private Cursor getContacts() {
// Run query
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME};
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '"
+ (mShowInvisible ? "0" : "1") + "'";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
return managedQuery(uri, projection, selection, selectionArgs,
sortOrder);
}

According to this: Get company name form Content Provider in android using new API's, you'll need to query the ContactsContract.Data and use these aliases http://developer.android.com/reference/android/provider/ContactsContract.CommonDataKinds.Organization.html

Query Contact members from a specified group?

I need to fetch the members for a specific group in android contacts.
I have the contact group names and their ID's
Can anyone provide me how to query the contacts provider for members in a particular group ?

Try this method:
private Cursor getContacts(String groupID) {
Uri uri = ContactsContract.Data.CONTENT_URI;
String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Data.CONTACT_ID,
ContactsContract.Data.DISPLAY_NAME
};
String selection = null;
String[] selectionArgs = null;
if(groupID != null && !"".equals(groupID)) {
selection = ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID
+ " = ?";
selectionArgs = new String[] { groupID };
}
else
selection = "1) GROUP BY (" + ContactsContract.Data.CONTACT_ID;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC ";
return getContentResolver().query(uri, projection,
selection, selectionArgs, sortOrder);
}
This works on Android 2.3.3 and lower, but doesn't work on Android 4+ and I don't currently know why.
UPD.
Adding custom string parameter "GROUP BY" to SQL query is denied in Android 4+, so I've founded this workaround:
private Cursor getContacts(String groupID) {
Uri uri = ContactsContract.Data.CONTENT_URI;
String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Data.CONTACT_ID,
ContactsContract.Data.DISPLAY_NAME
};
String selection = null;
String[] selectionArgs = null;
if(groupID != null && !"".equals(groupID)) {
selection = ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID
+ " = ?";
selectionArgs = new String[] { groupID };
}
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC ";
Cursor cursor = getContentResolver().query(uri, projection,
selection, selectionArgs, sortOrder);
MatrixCursor result = new MatrixCursor(projection);
Set<Long> seen = new HashSet<Long>();
while (cursor.moveToNext()) {
long raw = cursor.getLong(1);
if (!seen.contains(raw)) {
seen.add(raw);
result.addRow(new Object[] { cursor.getLong(0),
cursor.getLong(1), cursor.getString(2) });
}
}
return result;

Retrieving phone number from contact id : android

I'm trying to get contact data once a contact name has been clicked from my list view. As per the code below, I can log successfully the ID of my contact, but haven't managed to use the ContactsContract to retrieve the data. What's the best way to do this? (have tried Retrieve Contact Phone Number From URI in Android to not much avail)
EDIT 2 : Fixed code, now works
public void onCreate(Bundle savedInstanceState)
{
Log.v(TAG, "Activity State: onCreate()");
super.onCreate(savedInstanceState);
setContentView(R.layout.contact_manager);
mContactList = (ListView) findViewById(R.id.contactList);
populateContactList();
mContactList.setOnItemClickListener(new OnItemClickListener() {
String strid = Long.toString(id);
Cursor result = managedQuery(ContactsContract.Contacts.CONTENT_URI, null, ContactsContract.Contacts._ID +" = ?", new String[]{strid}, null);
if (result.moveToFirst()) {
Cursor c = getContentResolver().query(Data.CONTENT_URI,
new String[] {Data._ID, Phone.NUMBER, Phone.TYPE, Phone.LABEL},
Data.RAW_CONTACT_ID + "=?" + " AND "
+ Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE + "'",
new String[] {String.valueOf(strid)}, null);
if(c.moveToFirst()){
int phoneColumn = c.getColumnIndex("data1");
String phoneNumber = c.getString(phoneColumn);
Log.d("DATA",phoneNumber);
}
}
});
}
EDIT 1 : forgot some important stuff. The code is adapted from the ContactManager example from the Android dev site.
/**
* Populate the contact list based on account currently selected in the account spinner.
*/
private void populateContactList() {
// Build adapter with contact entries
Cursor cursor = getContacts();
String[] fields = new String[] {
ContactsContract.Data.DISPLAY_NAME
};
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.contact_entry, cursor,
fields, new int[] {R.id.contactEntryText});
mContactList.setAdapter(adapter);
}
/**
* Obtains the contact list for the currently selected account.
*
* #return A cursor for for accessing the contact list.
*/
private Cursor getContacts()
{
// Run query
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME
};
String selection = null;
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
return managedQuery(uri, projection, selection, selectionArgs, sortOrder);
}

Assuming you have a valid contactID, you can do this:
Cursor result = managedQuery(ContactsContract.Contacts.CONTENT_URI, null,
ContactsContract.Contacts._ID +" = ?",
new String[]{contactID}, null);
if (result.moveToFirst()) {
for(int i=0; i< result.getColumnCount(); i++){
Log.i("CONTACTSTAG", result.getColumnName(i) + ": "
+ result.getString(i));
}
}
You will have to change the ContactsContract.Contacts.CONTENT_URI and the where clause to the table that you are querying. The above code will print out a bunch of general info about a contact.

Android get a cursor only with contacts that have an email listed

Friends I want Contacts which have email and also sort in ascending order..
any one know how to get this list and sort..
Please help me and thanks in advance.
I am using this code.
MatrixCursor matCur = new MatrixCursor(new String[] { Contacts._ID,
Contacts.DISPLAY_NAME, "photo_id", "starred" });
Cursor cEmail = WP7Main.this.managedQuery(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
cEmail.moveToFirst();
if (cEmail.moveToFirst())
{
// String name =
// cursor.getString(cursor.getColumnIndexOrThrow(People.NAME));
String contactId = cEmail.getString(cEmail.getColumnIndex(ContactsContract.Contacts._ID));
Cursor emails = WP7Main.this.getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,ContactsContract.CommonDataKinds.Email.CONTACT_ID+ " = " + contactId, null, null);
String emailAddress = "";
while (emails.moveToNext())
{
// This would allow you get several email addresses
if (emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)) != null)
{
String[] columnValues = {
cEmail.getString(cEmail
.getColumnIndex("_id")),
cEmail.getString(cEmail
.getColumnIndex("display_name")),
cEmail.getString(cEmail
.getColumnIndex("photo_id")),
cEmail.getString(cEmail
.getColumnIndex("starred")) };
matCur.addRow(columnValues);
}
}
emails.close();
}

Try this:
/**
* #return A managed cursor of email contacts for the given activity.
*/
public static Cursor buildFilteredEmailCursor(Activity activity) {
final String my_sort_order = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
String my_selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '1'";
String[] eproj = new String[]{
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Email.DATA};
Uri uri = android.provider.ContactsContract.CommonDataKinds.Email.CONTENT_URI;
return activity.managedQuery(uri, eproj, my_selection, null, my_sort_order);
}

Use this query :
Cursor c = getContentResolver().query(Data.CONTENT_URI,
new String[]{Data.CONTACT_ID, Data.DISPLAY_NAME, Email.ADDRESS},
Data.MIMETYPE + "=?", new String[] {Email.CONTENT_TYPE}, Data.DISPLAY_NAME /* use Email.ADDRESS if you want to sort it using that*/);
