android initialize two times in two different activities -
not able initialize parse 2 times in 2 activity call data 2 classes of parse , put them in different list views. @ second time when opening contact activity action item app stops
main activity.java
public class mainactivity extends actionbaractivity { private countryadapter madapter; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); parse.initialize(this, "0fgkgokshcbpqspy**********", "f1hz9w4c***********"); parseobject.registersubclass(country.class); madapter = new countryadapter(this, new arraylist<country>()); listview mlistview = (listview) findviewbyid(r.id.country_list); mlistview.setadapter(madapter); updatedata(); } @override public boolean oncreateoptionsmenu(menu menu) { getmenuinflater().inflate(r.menu.menu_main, menu); return true; } @override public boolean onoptionsitemselected(menuitem item) { int id = item.getitemid(); if (id == r.id.action_contact) { intent = new intent(this, contactactivity.class); startactivity(i); return true; } return super.onoptionsitemselected(item); } public void updatedata() { parsequery<country> query = parsequery.getquery(country.class); query.setcachepolicy(parsequery.cachepolicy.cache_then_network); query.findinbackground(new findcallback<country>() { @override public void done(list<country> countrys, com.parse.parseexception e) { if (countrys != null) { madapter.clear(); (int = 0; < countrys.size(); i++) { madapter.add(countrys.get(i)); } } } }); } } contactactivity.java
public class contactactivity extends actionbaractivity { private contactadapter madapter; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_contact); parse.initialize(this, "0fgkgoksh********************", "f1hz9w4cko2ag*******************"); parseobject.registersubclass(contact.class); madapter = new contactadapter(this, new arraylist<contact>()); listview mlistview = (listview) findviewbyid(r.id.contact_list); mlistview.setadapter(madapter); updatedata(); } @override public boolean oncreateoptionsmenu(menu menu) { getmenuinflater().inflate(r.menu.menu_contact, menu); return true; } @override public boolean onoptionsitemselected(menuitem item) { return super.onoptionsitemselected(item); } public void updatedata() { parsequery<contact> query = parsequery.getquery(contact.class); query.setcachepolicy(parsequery.cachepolicy.cache_then_network); query.findinbackground(new findcallback<contact>() { @override public void done(list<contact> contact, com.parse.parseexception e) { if (contact != null) { madapter.clear(); (int = 0; < contact.size(); i++) { madapter.add(contact.get(i)); } } } }); } }
you should initialize parse in class extends application class this
public class myapplication extends application { @override public void oncreate() { super.oncreate(); parse.initialize(this, "xxxxxxxxxxxx", "xxxxxxxxx"); } } and put application class name in manifest file like
<application android:name=".myapplication" />
