Repurposing Android Requires Tools that
can Debug the Full Stack
MIPS’ licensees, partners, and the community will
contribute much of the longer-term effort

Android versus Traditional Linux Systems
Traditional Linux Platforms Android
Single language (some assembly,
mostly C)
Multiple languages (assembly, C/C++,
Java, JavaScript, ActionScript)
Single/few processes Multiple processes, with program logic
straddling process barriers
Applications mostly execute in User
Space
Applications partitioned between User
and Kernel Space
One process per application Multiple processes per application
Android Software Development
Android is a Juggling Act!

Why is Android Development so Difficult?
(1) Android applications
cross language barrier Java
C/C++
Javascript & Actionscript
(2) Android applications
cross process barrier Client/Server
JNI
CORBA/IDL
(3) Android applications
cross protection barrier To and From User / Kernel Space
