Solution: If you are using Java on Google app engine, please add a file datastore-indexes.xml in WEB-INF folder with following content...


<?xml version="1.0" encoding="UTF-8"?>
<datastore-indexes autoGenerate="true">
   <datastore-index kind="TrackUserDetails" ancestor="false" source="manual">
        <property name="userId" direction="asc"/>
        <property name="inTime" direction="desc"/>
   </datastore-index>
</datastore-indexes>


You can define index here for datastore.
