Be sure you are inserting a row with a valid primary key, i.e., make it unique in the table (I think you are having this exeception just because you're trying to insert a row which primary key is already defined in the same database table).

correct the definition of your database ..because on declaring fields as not null ..you must send some data to every field.. so remove not nul1 from data fields where it is not required

Make sure that you are not trying to insert some value in there that is not unique. Make sure that you are not trying to skip any "not null" values in your insert. Either provide a value of not null columns or define a default value.

On a different note you are defining KEY_CONTENT1 and so on in 2 different classes with same values. Don't repeat. You are using a static context for them so define them in one class and use the static context to retrieve them else where.

In your database schema you declared everything as NOT NULL, but in your insert your don't have a value for every field. SQLite throws an exception because it doesn't know what to insert into the fields. Remove the NOT NULL constraints so that SQlite can insert a null value as default or add a value for every field.
