Snap for 8191477 from 5d7545beb733ff003c0eed9693bf3e1e6eb92e3b to tm-frc-ipsec-release Change-Id: If249d33072f9c15bbaf9c7190b599210882399d8
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 = "0.10"
Example of initialization on activity creation, with log configuration:
#[macro_use] extern crate log; extern crate android_logger; use log::Level; use android_logger::{Config,FilterBuilder}; fn native_activity_create() { android_logger::init_once( Config::default() .with_min_level(Level::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::Level; use android_logger::Config; fn native_activity_create() { android_logger::init_once( Config::default().with_min_level(Level::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.
