Snap for 9719949 from 5ecce4149b8f2aaf730c22e753a9a4a2e4415c97 to udc-release Change-Id: I6f8abf162bcafe1cc00d0ac088fc8b5d6649ffb4
This library is a drop-in replacement for env_logger. Instead, it outputs messages to android's logcat.
This only works on Android and requires linking to log which is only available under android. With Cargo, it is possible to conditionally require this library:
[target.'cfg(target_os = "android")'.dependencies] android_logger = "0.11"
Example of initialization on activity creation, with log configuration:
#[macro_use] extern crate log; extern crate android_logger; use log::LevelFilter; use android_logger::{Config,FilterBuilder}; fn native_activity_create() { android_logger::init_once( Config::default() .with_max_level(LevelFilter::Trace) // limit log level .with_tag("mytag") // logs will show under mytag tag .with_filter( // configure messages for specific crate FilterBuilder::new() .parse("debug,hello::crate=error") .build()) ); trace!("this is a verbose {}", "message"); error!("this is printed by default"); }
To allow all logs, use the default configuration with min level Trace:
#[macro_use] extern crate log; extern crate android_logger; use log::LevelFilter; use android_logger::Config; fn native_activity_create() { android_logger::init_once( Config::default().with_max_level(LevelFilter::Trace), ); }
There is a caveat that this library can only be initialized once (hence the init_once function name). However, Android native activity can be re-created every time the screen is rotated, resulting in multiple initialization calls. Therefore this library will only log a warning for subsequent init_once calls.
This library ensures that logged messages do not overflow Android log message limits by efficiently splitting messages into chunks.
