Answer 1

Replace

Key_Home + " TEXT,");

with

Key_Home + " TEXT)");

There's a , so that further column specifications are expected but there's nothing followin so you need to terminate the table specification with ).

Also, you should not be catching SQLiteException in database helper onCreate(). When onCreate() returns normally, the database creation is assumed to be succesful.

After fixing the problems, uninstall your app so the old, incorrect database file is removed and onCreate() is run again.

Also in your open() you seem to call onCreate() yourself. Don't do that. get{Read,Writ}ableDatabase() will do it for you when needed.

Answer 2

You're not closing off your SQL statement. For example:

this:

db.execSQL("CREATE TABLE  " + Places_Table + "(" +
                    Key_ID + " INT PRIMARY KEY NOT NULL," +
                    Key_Name + " TEXT NOT NULL," +
                    Key_Phone + " TEXT NOT NULL," +
                    Key_Address + " TEXT NOT NULL," +
                    Key_Website + " TEXT," +
                    Key_Home + " TEXT,");

Should be:

db.execSQL("CREATE TABLE  " + Places_Table + "(" +
                    Key_ID + " INT PRIMARY KEY NOT NULL," +
                    Key_Name + " TEXT NOT NULL," +
                    Key_Phone + " TEXT NOT NULL," +
                    Key_Address + " TEXT NOT NULL," +
                    Key_Website + " TEXT," +
                    Key_Home + " TEXT)");

Which will then close off the create table statement. It was expecting another parameter, due to the comma.
