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."
