Android : Android SQLite CREATE TABLE Syntax Error

I'm getting the following error when I execute SQL in my app:

android.database.sqlite.SQLiteException: near "(": syntax error (code 1): , while compiling: CREATE TABLE IF NOT EXISTS data (id int auto_increment primary key, data_type int default 0, data float not null, time timestamp default now());

Code causing error:

@Override
public void onCreate(SQLiteDatabase db){
    db.execSQL("CREATE TABLE IF NOT EXISTS " + DATA_TABLE + " (id int auto_increment primary key, data_type int default 0, data float not null, time timestamp default now());");
}

And LogCat when error occurs:

I've run the line itself through a syntax error checker and it seems to be fine.
