public static String getContactName(final String phoneNumber,Context context) {
        Uri uri;
        String[] projection;
        Uri mBaseUri = Contacts.Phones.CONTENT_FILTER_URL;
        projection = new String[] { android.provider.Contacts.People.NAME };
        try {
            Class<?> c = Class
                    .forName("android.provider.ContactsContract$PhoneLookup");
            mBaseUri = (Uri) c.getField("CONTENT_FILTER_URI").get(mBaseUri);
            projection = new String[] { "display_name" };
        } catch (Exception e) {
        }
        uri = Uri.withAppendedPath(mBaseUri, Uri.encode(phoneNumber));
        Cursor cursor = context.getContentResolver().query(uri, projection, null,
                null, null);

        String contactName = "";

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