If we install our support libraries into the NDK we later run into include path order issues that result in strange errors around the inclusion of math.h (because we find the C version of that include file that ships with the NDK before we find the libstdc++ version of math.h (because the include path for our support libraries is listed before the libstdc++ include search path). By having a distinct install-root for our libraries we can avoid this problem. Remove the previous hack that tried to work around the symptoms of this issue.

Tool repo to crosscompile subsurface to android-arm
---------------------------------------------------
Dependencies:
1. android_sdk, android_ndk and Qt for android. See step 0.
2. cmake
3. ant
4. Java JDK
5. working adb is recommended
6. dependencies of libdivecomputer and subsurface -
visit http://subsurface.hohndel.org/documentation/building/
By far the easiest way to do this is using the Android build container which is
used to create the official builds. That has all the dependencies ready and
makes things a lot easier.
Run the docker image: docker://subsurface/android-builder:5.13.10
Check out the sources inside the container, make sure the following links
are available in parallel to the source directory
ln -s /android/Qt .
ln -s /android/android-ndk-r18b .
ln -s /android/android-sdk-linux .
and run the build wrapper from the directory above the source directory
bash -x subsurface/packaging/android/android-build-wrapper.sh
This should create a pair of unsigned but otherwise working APKs (for 32 and 64
bit ARM).
Alternatively, steps to install using your own Linux machine:
Step 0.
Grab..
Android ndk from: http://developer.android.com/tools/sdk/ndk/index.html
Android sdk from: http://developer.android.com/sdk/index.html#download
And QT for android from: http://qt-project.org/downloads
Step 1.
Extract and install these into known directories.
Have a look in the top of build.sh for where the cross build tool expects
them. By default thats is: ../../../android-ndk-r9d ../../../android-sdk-linux
and ../../../Qt/5.5 (or Qt/5.6)
Step 2.
Run bash build.sh in the terminal. By default it builds for arm but you
can pass x86 as first arg to build.sh to have it build for x86. Nice when
debugging in a fast emulator.
The script will download and build the whole dependency chain.
After this, subsurface will be built for android.
The output folder is subsurface-build-arm/android_build and your newly
created apk shows up as:
subsurface-build-arm/android_build/bin/QtApp-debug.apk
Where the x86 apk shows up when built for x86 is left as a exercise for the
reader.
