Android: Retrieve contact name from phone number

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.

Solution

For that you need to use the optimized PhoneLookup provider as described.

Add the permission to AndroidManifest.xml:

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

Then:

public String getContactName(final String phoneNumber, Context context)
{
    Uri uri=Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI,Uri.encode(phoneNumber));

    String[] projection = new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME};

    String contactName="";
    Cursor cursor=context.getContentResolver().query(uri,projection,null,null,null);

    if (cursor != null) {
        if(cursor.moveToFirst()) {
            contactName=cursor.getString(0);
        }
        cursor.close();
    }

    return contactName;
}
