title: How can I query contact information based on a phone number
body: <p>I am trying to query contact information based on a phone number on android 1.6. This is the code I tried. But I get count equals to 0 in my cursor.</p>
  
  <pre><code>    String selection = "PHONE_NUMBERS_EQUAL(" + People.Phones.NUMBER + " , "   + phoneNumber + ")";
      Cursor cursor = mContext.getContentResolver().query(People.CONTENT_URI,
              new String[] {People._ID, People.NAME, People.Phones.NUMBER},
              selection, null, null);
  </code></pre>
  
  <p>Do you have any idea why it is not working?</p>
  
  <p>Thank you.</p>
