This pull request implements the following:

Created a new example called rust_android_logging based on the current example app
Initialized a new Rust library project with logging dependencies
Implemented logging functions in src/lib.rs and exported them with #[no_mangle]
Used cargo-ndk to cross-compile the Rust code for Android architectures
Added the compiled Rust library to the Android project's jniLibs
Created a JNI wrapper in Java/Kotlin to call the Rust logging functions
Compiled and tested the Android project with the new logging functionality
