Android APIs are Java. Since 2010, Google provides the NDK (a SDK) for C/C++ developers.
The NDK offers two ways:
- for android 1.5 devices, you can load an elf library and uses it from the java application via a JNI bridge
- for android 2.3 devices, you can use a NativeActivity to bypass the Java Activity code for Fullscreen Application.
The NDK offers few C/C++ API:
- a pseudo libc called bionics: many functions aren't availabled
- a pthread library
- OpenGL ES 1.x (>Android 1.5) and OpenGL ES 2.x (Android 2.0)
- OpenSL (limited support on Android 2.3)
But many API are Java only (also available via JNI).
NDK 5 version is the first usable for C++ developers because it offers:
- RTTI
- Exceptions supports
- STLport
- gdb support for multi-threaded programs
The most painful operation is debugging on android devices. So i develop my own multi-platform framework (OS X, Windows, Linux, iOS and Android) to debug first on desktop platform, next iOS platform (on Simulator) and Last (Android).
The android Emulator (not a simulator) have a poor performance and can't emulate OpenGL ES 2.x. I recommend real devices to develop.
