Android: Retrieve contact name from phone number

Question

I would like to retrieve the name of a contact associated with an incoming telephone number. As I process the incoming number in the broascastreceiver having a String with the name of the incoming caller would help my project greatly.

I would think this involves a query using the sql WHERE clause as a filter, but do I need to sort the contacts? An example or hint would be of great assistance.

Although this has already been answered, but here is the complete function to get the contact name from number. Hope it will help others:

public static String getContactName(Context context, String phoneNumber) {     ContentResolver cr = context.getContentResolver();     Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));     Cursor cursor = cr.query(uri, new String[]{PhoneLookup.DISPLAY_NAME}, null, null, null);     if (cursor == null) {         return null;     }     String contactName = null;     if(cursor.moveToFirst()) {         contactName = cursor.getString(cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME));     }      if(cursor != null && !cursor.isClosed()) {         cursor.close();     }      return contactName; }

You will have to ask for this permission:

<uses-permission android:name="android.permission.READ_CONTACTS"/>
