Android App Crashing On Calling Sqlitehelper

I have been using this tutorial for some part, but I had to make some little changes and my app crashes on mobile phone. There are no errors in code, though! http://www.vogella.com

Solution 1:

you forget to place comma(,) after every column name in create table query change it as:

private static final String DATABASE_CREATE =
        "CREATE TABLE " + TABLE_NAME + 
         " (" +
        COLUMN_NAME_SP + " text not null, " +
        COLUMN_NAME_ST + " text not null " +
        ");";
