Android
=======
Android is quite different from a traditional Linux distribution
and comes with its own set of libraries.
This guide targets libcamera developers who want to build-test the Android support.
Cross-compilation
-----------------
.. code-block:: ini
[constants]
# TODO: edit these paths for your own locations
ndk = '/mnt/work/aosp/android-ndk-r26b'
# see: https://android.googlesource.com/platform/ndk/+/master/docs/BuildSystemMaintainers.md#target-selection
triple = 'x86_64-linux-android'
android_api_level = '33'
target = triple + android_api_level
toolchain = ndk / 'toolchains/llvm/prebuilt/linux-x86_64/bin'
[properties]
cpp_stdlib = 'vndk'
[built-in options]
cpp_args = ['-target', target]
[binaries]
c = toolchain / target + '-clang'
cpp = toolchain / target + '-clang++'
ar = toolchain / 'llvm-ar'
strip = toolchain / 'llvm-strip'
config = toolchain / 'llvm-config'
[host_machine]
system = 'linux'
cpu_family ='x86_64'
cpu = 'amd64'
endian = 'little'
1. Edit the ``ndk`` constant to point to your system's NDK location
2. Save the above cross file in ``~/.local/share/meson/cross/x86_64-linux-android.txt``.
.. code::
meson setup --cross-file=x86_64-linux-android.txt --prefix=/ -Dandroid=enabled -Dandroid_platform=generic -Dpipelines=simple build; meson compile -C build
