  1. POQuery contacts Thumbnail from contact number
    text
    copied!<p>i am trying to retreive the contacts thumbnail from phonebook given a phone number or email ID. Th code that i wrote works but takes a very long time because it is querying the whole contacts(not efficient at all).</p> <p>Below is the code</p> <pre><code>Cursor cursor; String[] queryColumns = { ContactsContract.Contacts.PHOTO_THUMBNAIL_URI,ContactsContract.Contacts._ID }; ContentResolver cr = getContentResolver(); cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, queryColumns, null, null, null); cursor.moveToFirst(); while (cursor.moveToNext() &amp;&amp; continueSearch) { String[] phonesAndEmails = extractPhonesAndEmails(Integer.parseInt(cursor.getString(1))); for(int g=0;g&lt;phonesAndEmails.length;g++){ if(phonesAndEmails[g].equals(searchFor)){ contactThumbUri = cursor.getString(0); MyUtils.addLog("Found Match **************" + contactThumbUri); continueSearch=false; } } } cursor.close(); </code></pre> <p>extractPhonesAndEmails gets a String[] of all the numbers and emails for the contactID passed to it.</p> <p>I got another approach from SO that uses PhoneLookup but that giver=s me an error. I checke to see what columns is this cursor returning. i got only two columns one of which as contact name and the other was an integer probably the ID. Here is the second code;</p> <pre><code>if(!MyUtils.checkIfEmailID(searchFor)){ Cursor mCursor; Uri qUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(searchFor)); String[] mqueryColumns = {PhoneLookup.PHOTO_URI}; mCursor = getContentResolver().query(qUri, mqueryColumns,null, null, null); MyUtils.addLog(mCursor.getCount() + " count"); MyUtils.addLog(mCursor.getString(0)); mCursor.moveToFirst(); while (mCursor.moveToNext() &amp;&amp; continueSearch) { contactThumbUri=mCursor.getString(0); MyUtils.addLog(contactThumbUri); continueSearch=false; } mCursor.close(); } </code></pre> <p>please help to either optimize my first code or sort out the error in the second code.Thanks a lot.</p>
