Weeks ago, Google announced the first public release of Android NDK.
I was so excited because the IMS Client I'm developing is written in pure C/C++ (Only Java was supported).
Before Android NDK, I have looked at Google's Android SDK and I found that they are using non-standard JVM. This mean that applications developed using J2ME can't run on Android devices. Thanks to Dalvik virtual machine.
It was clear that I won't rewrite xxx thousand lines of code for Android mobile devices which represent less than 1 percent of all mobile devices.
It's amazing to think that Android OS will gain momentum without compliant embedded JVM. First deception.
Because performance is critical for us and we don't have time and money to rewrite an application which will only run on Android devices, we decided to wait for the Android NDK.
The first release of Android NDK only comes with these native libraries:
# libc (C library)
# libm (math library)
# libz (Zlib compression)
# liblog (Android logging)
This mean that you don't have:
# STL support (string, list, map, queue, ....)
# C++ exceptions handling
# Threading support
# Cryptography support
# Secure sockets/transport (SSL, TLS, S/MIME, ...)
# Classes to access the system resources (webcam, soundcard, drivers, ...)
# .... to be continued
Of course, you must use JNI if you want to have access to the native libraries. I let you imagine about performance ...
Second deception.
