java - cursor wont return a row no matter what -


i'm trying latest row have inserted db, cursor. have tried many types of query, , nothing seem work.

, here code: 

public expense createexpense(expense expense) {     contentvalues values = new contentvalues();     values.put(expdatabase.column_description, expense.getdesc());     values.put(expdatabase.column_amount, expense.getamount());     values.put(expdatabase.column_date, expense.getdate().tostring());     values.put(expdatabase.column_category, expense.getcategory());      integer insertid =(int) database.insert(expdatabase.table_name, null,             values);          string id="'"+insertid.tostring()+"'";      cursor c = database.query(expdatabase.table_name, null,             null, null, null, null, null); int i=  c.getcount();       cursor cursor= database.query(expdatabase.table_name, null,expdatabase.column_id+"="+id, null, null, null, null);

*the insert method works, have seen row in db table. *the getcount returns same number insertid

but when try last row cursor, nothing, see in cursor returned -1 in number of rows.

im lost. please me :(

if i'm not mistaken have problem on query

string[] fields = new string[]{expdatabase.column_id}; cursor cursor= database.query(expdatabase.table_name, fields,expdatabase.column_id+"="+id, null, null, null, null);
