Android: Signed APK issue - no default constructor when there is one

I'm getting the 

'This class should provide a default constructor'

error when i'm trying to build the APK

this is my DBHelper class:

public class DBHelper extends SQLiteOpenHelper {

// create variables
public DBHelper(Context context)
{
    super(context, DATABASE_NAME , null, 1);
}
// onCreate

I was under the impression that

public DBHelper(Context context)

was the default constructor? And have checked other answers with this and can't find anything to help...

Thanks in advance

As the error suggest

Error: This class should provide a default constructor (a public constructor with no arguments)

try this way:

public class DBHelper extends SQLiteOpenHelper {

// create variables

public DBHelper(){
    super();
}

public DBHelper(Context context)
{
    super(context, DATABASE_NAME , null, 1);
}



// onCreate

A default constructor is a constructor without any arguments.

SQLiteOpenHelper needs at least a context so you won't be able to create a default constructor for your DBHelper. Are you sure this is the class causing this error ?
