Thanks to Bernard Parisse for write and share Giac library

• Firs of All download and setup Android Studio to build the Apk.
• Download and setup Android NDK Revision 10e (only this ndk revision are supported to build it)

foo@bar:~$ wget https://dl.google.com/android/repository/android-ndk-r10e-linux-x86_64.zip
foo@bar:~$ unzip android-ndk-r10e-linux-x86_64.zip -d android-ndk-r10

• Download giac sorce code and compile JNI libs

foo@bar:~$ mkdir build_xcas_pad && cd build_xcas_pad
foo@bar:~$ wget https://www-fourier.ujf-grenoble.fr/~parisse/debian/dists/stable/main/source/giac_1.4.9-1.tar.gz
foo@bar:~$ tar -xvf giac_1.4.9-1.tar.gz
foo@bar:~$ cd giac-1.4.9
foo@bar:~$ cp src/config.h.android src/config.h
foo@bar:~$ git clone https://github.com/xcaspad/android_xcaspad.git
foo@bar:~$ cd android_xcaspad/jni/
foo@bar:~$ ~/android-ndk-r10/android-ndk-r10e/ndk-build

• Once again JNI libs(armeabi-v7a, x86) are compiled we can procced to open the Android Studio project and build the Apk.
