Parse Query not working outside Main Activity (Parse.com Android) -

i have class in parse.com. class name classa. class contains 1 column named owner. multiple observations within classa can have same owner. trying formulate query based on owner. query syntax this..

    parsequery<parseobject> itemsall = new parsequery<parseobject>("classa");     itemsall.whereequalto("owner", "ownername");     list<parseobject> allitems = new arraylist<>();     try {         allitems = itemsall.find();     } catch (parseexception e) {         log.e("error", e.getmessage());         e.printstacktrace();         toast.maketext(getapplicationcontext(),"error syncing",toast.length_long).show();     }     log.d("size", string.valueof(allitems.size())); 

i have added parse authentication code in separate starterapplication.java file. syntax is..

public class starterapplication extends application {  @override public void oncreate() { super.oncreate();  // enable local datastore. parse.enablelocaldatastore(this);  // add initialization code here parse.initialize(this, "app_key", "app_token");  parseuser.enableautomaticuser(); parseacl defaultacl = new parseacl(); // optionally enable public read access. // defaultacl.setpublicreadaccess(true); parseacl.setdefaultacl(defaultacl, true); } } 

my android manifest file looks this...

<application     android:name=".starterapplication"     android:allowbackup="true"     android:icon="@drawable/app_icon"     android:label="@string/app_name"     android:theme="@style/customactionbartheme" >     <activity         android:name=".mainactivity"         android:label="@string/app_name"         android:screenorientation="portrait" >         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>     <activity         android:name=".activityone"         android:label="@string/app_name"         android:screenorientation="portrait" >     </activity> </application> 

i using above written query in both mainactivity , activityone. query produces correct result when called mainactivity returns empty list (size 0) inside activityone. can please wrong. can't quite figure out. in advance.
