i'm working custom adapter:

oncreate of mainactivity:

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_my);     getwindow().addflags(windowmanager.layoutparams.flag_keep_screen_on);      gridview = (gridview) findviewbyid(r.id.gridview);      db = new databasehelper(this);     db.open();     mcursor = db.getallrecords();      mycursoradapter madapter = new mycursoradapter(myactivity.this, mcursor, false);     madapter.notifydatasetchanged();      gridview.setadapter(madapter);     mcursor.close();     db.close(); } 

mycursoradapter.java

to sure, added closestatements in onpause , ondestroy of mainactivity, this:

@override protected void ondestroy() {     if (mcursor != null) {         mcursor.close();     }     if (db != null) {         db.close();     } }  @override protected void onpause() {     if (mcursor != null) {         mcursor.close();     }     if (db != null) {         db.close();     } } 

the whole error:
