This paper introduces detailed methods for developing and porting an Android application on the Intel Atom platform, and discusses the best known methods for developing applications using the Android Native Development Kit (NDK) and optimizing performance. Android developers can use this document as a reference to build high quality applications for the Intel Architecture.
1. Android Application Classification
Android applications can be classified into two types as shown in Figure 1.
People say that GCC (GNU Compiler Collection) cannot generate effective code compared to other proprietary compilers. Is it a myth or reality? We will try to figure out how things really are with GCC. So, how can GCC compiler produce more effective code? We will describe some optional hints for x86 Linux platform "C", "C++" and "Fortran" compilation that help you get more performance from GCC. It should be useful for those customers and developers who need higher performance, but do not use proprietary compilers for various reasons.
