Search contact by phone number

Question

In my app, user writes a phone number, and I want to find the contact name with that phone number?

I usually search the contacts like this:

Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,             null, null, null, null); 

But I do this to access all contacts... In this app I only want to get the contact name of the given phone number... How can I restrict the query?

Or do I have to go trough all contacts and see if any has the given phone number? But I believe that this can be very slow this way...

If you want the complete code:

public String getContactDisplayNameByNumber(String number) {     Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));     String name = "?";      ContentResolver contentResolver = getContentResolver();     Cursor contactLookup = contentResolver.query(uri, new String[] {BaseColumns._ID,             ContactsContract.PhoneLookup.DISPLAY_NAME }, null, null, null);      try {         if (contactLookup != null && contactLookup.getCount() > 0) {             contactLookup.moveToNext();             name = contactLookup.getString(contactLookup.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));             //String contactId = contactLookup.getString(contactLookup.getColumnIndex(BaseColumns._ID));         }     } finally {         if (contactLookup != null) {             contactLookup.close();         }     }      return name; }
