Android Count records in SQL database -
on start of app im trying toast number of records in database
in main activity tried
final dbadapter db = new dbadapter(this); db.open(); cursor c = db.getasset3(null); int counter=c.getcount(); toast.maketext(getbasecontext(), counter, toast.length_long).show();
and in dbhelper have next method
public cursor getasset3(editable strname) throws sqlexception { cursor mcursor = db.rawquery("select * database_table",null); homecoming mcursor; }
the app keeps crashes on start
any ideas im going wrong
any help appreciated
mark
change
toast.maketext(getbasecontext(), counter, toast.length_long).show();
to
toast.maketext(getbasecontext(), string.valueof(counter), toast.length_long).show();
because want display int
in maketext
,caste string
.for more info see android toast maketext
edit
and alter query like
cursor mcursor = db.rawquery("select * " + database_table,null);
where database_table
name of table.
android sql count
