# Create an AAR with libsodium in all combinations of static | shared | minimal | full.
#
# The x86 static library will not work due to text relocation rules, so static x86 versions are limited to shared libraries.
# To simplify linking, library variants have distinct names: sodium, sodium-static, sodium-minimal and sodium-minimal-static.

echo "Congrats you have built an AAR containing libsodium! To use it with
gradle or cmake (as set by default for Android Studio projects):
- Edit the app/build.gradle file to add:
android {
buildFeatures {
prefab true
}
}
and
dependencies {
implementation fileTree(dir:'path/to/aar/',include:['libsodium-$SODIUM_VERSION.aar'])
}
Optionally, store multiple AAR files in the same folder and include '*.aar'
- Edit your module's CMakeLists.txt file to add:
find_package(sodium REQUIRED CONFIG)
- Then, specify 'sodium::x' as an item in the relevant 'target_link_libraries' statement.
The first part is the AAR name and should be 'sodium'.
The second part ('x', to be replaced) should be set to:
- 'sodium' for the full shared library,
- 'sodium-static' for the full static library
- 'sodium-minimal' for the minimal shared library, or
- 'sodium-minimal-static' for the minimal static library."
