Build system doesn’t play
well with JDK 7 (Android SDK issue)

Build system doesn’t play
well with JDK 7 (Android SDK issue)
Can be sort of fixed though
decompiling build system and
manual patching
Bitter
Bundles OLD stlport
No Visual Studio debug visualizers
support
Bitter
Multithreading problems:
Memory can be freed only from thread it was allocated
in.
Enjoy!
Bitter
Network problems:
One failed request can hang your
application

Network problems:
One failed request can hang your
application
Workaround:
Have no more then one request at a
time
Bitter
Network problems:
One failed request can hang your
application
Workaround:
Turn off some optimisations for
Marmalade internal multitasking features
Bitter
Extensions problems:
(missing features, bugs)
Bitter
Dependencies:
You need IwUtil for tracing and it depends on a whole lot of stuff
(libjpg, libpng, zlib, etc.)
Bitter
Sometimes updates randomly break stuff:
• Problems with ATI cards on Simulator • Appending ‘\n’ to HTTP request body • Regressions • etc.
Bitter
Virtually no support
Bugs can be ignored for months
Bitter
• Video playback problems • Native UI and Input problems • Things I don’t remember
Sour
Memory management:
Marmalade allocates one continuous chunk of memory from system.
Replaces malloc/new.
Have to write your own memory allocator on top of one provided by marmalade.
Sour
No debugging on device
Logging is your friend
Conclusion
Was it worth it?
Conclusion
Be ready to reimplement stuff
(we reimplemented facebook, music, sound and filesystem
extensions, heavily modified others)
