Logging

You should use the log crate to automatically log to logcat (on-device) or stdout (on-host):

hello_rust_logs/Android.bp:

{{#include logging/Android.bp}}

hello_rust_logs/src/main.rs:

{{#include logging/src/main.rs:main}}

Build, push, and run the binary on your device:

{{#include build_all.sh:hello_rust_logs}}

The logs show up in adb logcat:

adb logcat -s rust
