add android make files to Wrapper folder and its sub folders about openni2

Actually, there is a reason for that.
Current OpenNI solution for Android is only for native usage (i.e. when running as part of the system). In this configuration, the java API is meaningless.
Having OpenNI exposed to applications is a bit more complicated then having java APIs. Some problems that need to be addressed are:

• USB device permissions - the application needs to get specific permissions to the USB device
• Access to files. OpenNI (and NiTE) assume some files are installed as part of the installation process, which is a bit different when using APKs.

In any case, we're currently working on a complete Android solution.

is there any time schedule for the android solution?

[eddiecohen]

I should have a first unstable version in the coming days.

thanks for the info, because I'm currently hacking my own version

[eddiecohen]

Everything is committed to 'develop'. Enjoy!

[christiankerl]

ok, I will give it a try. on which device/android version did you test the code?

[eddiecohen]

I tested it on an Asus Transformer with Android 4.2.

ok, works for me on Nexus 7 (2013) and Android 4.3, thanks a lot

just in case someone reads this: because of a bug in the Nexus 7 Android version the language has to be set to English (US) otherwise the PS1080 is not recognized by the Android USB API and the OpenNI2 Android SDK won't work
