Marmalade SDK Exception cannot open file iwui style style group bin for serialising

I made a simple IW2D app with Marmalade SDK, it worked fine in the Windows emulator but when I deployed to Android I received this exception:

cannot open file iwui_style/style.group.bin for serialising (read), Did you include this file in your mkb assets block

The solution was  to add this block to my MKB file

assets
{
 (data-ram/data-gles1)
 ui.group.bin
 (data-ram/data-gles1)
 iwui_style/style.group.bin
}

Marmalade SDK Exception Multiply Overflow

I was performing some transformations (scaling) on 2D sprites like this:

CIwMat2D matrix;
rot.Scale(IW_FIXED(2));

When I ran the app I received the following exception:

IwAssert failure (GEOM, 350). Message: Multiply overflow

The avoid this exception, you must set your matrix to the Identity matrix before applying transformations on it like this:

CIwMat2D matrix;
matrix.SetIdentity();
rot.Scale(IW_FIXED(2));

Marmalade SDK Output Debug messages

If you want to output debug messages in your output console in Visual studio, you can do it in two ways:

1. Use standard C++ output stream cout

   cout<<"Your Message"<<endl;

2. use the Marmalade  s3eDebug module: first include the header:

   #include "s3eDebug.h"

   then

   s3eDebugOutputString("Your Message");
   

   to display integers you have to convert them to C style strings first:

   int x=10;
   char buffer[10];
   //convert the int to a char array
   sprintf(buffer,"%d",x);
   s3eDebugOutputString(buffer);
