Answer 1

The error is clear:

...
.sqlite.SQLiteException: table userInfo has no column named userInfo (code 1):
, while compiling: INSERT INTO userInfo(password,userInfo) VALUES (?,?) at
...

When you are invoking the method

public boolean addInfo( ContentValues values )

You are passing as a content value, a value named with the same name as the table. You have to check two things:

1. Where you are using UserProfile.Users.TABLE_NAME (that I suppose it has the value userInfo
2. Check what you are passing to content values used by addInfo method.

Hope it helps.

Answer 2

If you are trying to add new row to the table after it has been created, try to remove the table and create it again.

to remove

 sqLiteDatabase.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);

after this, you can recreate the table again

Answer 3

You have to increase your version of database after then do changes in On-upgrade method of sqlite.

   @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

        if(newVersion > oldVersion){
            db.execSQL("DROP TABLE IF EXISTS " +......);
            db.execSQL("CREATE TABLE IF NOT EXISTS " +......);

            insertColumnIfNotAvailableinTable(SQLiteDatabase db, String tableName, String columnName, String columnType);



        }
    }
