Hi,

I'm trying to access to access a database from a class...

This is the code i use..

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

DATABASE_mob mDbHelper = new DATABASE_mob(this);
 
              mDbHelper.open();
 
Parsed in 0.031 seconds,  using GeSHi 1.0.8.4

I get an error while compiling which says,
The constructor DATABASE_mob(*CLASSNAME*) is undefined

Hope to find a solution to this.

Thanks,
Immanuel

Pretty simple, you didn't implement your DATABASE_mob constructor correctly, so it doesn't support have a Context as argument... Post your code and we will help.

Sorry i dint update this thread..

I found a solution to this problem.. I was accepting a context as a parameter into the constructor of the class that managed the database.

I could not obtain a context of the class which gave the error.. So i got it from the calling activity and passed it to the constructor of the class that managed the database..

Hope i'm clear...
Thanks for the reply..

Yup it's clear and passing the Activity to it's children is almost always the way to do stuff like this.
